BMW N54 Problems to Expect – Reliability Report

So, you’re looking at a BMW with the N54 engine but you’ve heard that this may not be the most reliable engine in the BMW line up. Hi guys and welcome back to the SimpleCarGuy channel. Today, we will talk about the history, common problems, issues solved over time, how reliable the engine is 15 years later as well as my personal experience.

The reason I’m making this video is because I owned a BMW 335i e92 with the N54 engine for about 4 years from 2013 to 2017 and I wanted to catch myself up and see how the reliability has been since I sold my car! This is also part of a small series where I’m looking into engines I own or have owned and creating reliability reports like this video. BMW N55 video is coming up soon, so subscribe to see it and hit that like button to support the channel!

History/Background:

BMW N54 is one of the best straight six engines every made by BMW for a few very good reasons. Not only was it the first mass produced BMW turbocharged engine, but it also came with a forged crankshaft and connecting rods leaving HUGE tuning potential. Even though the stock engine made 302 HP, it’s not very difficult to get it up to 500hp or even much, much more. So, how can this reward winning engine [show which awards] have issues? Well, while the actual engine has had some amazing innovations and engineering, a lot of the accessories and  auxiliary components are not as well designed. Of course, when looking at a used BMW with the N54 engine, it doesn’t help that a lot of them have been tuned and driven hard! [HUGE tuning potential and people love it, but also abuse it] So, let’s take a look at some common problems you can expect on a BMW N54 engine

Common Issues:

Even though there were 3 different power figures for this engine, mechanically its basically the same engine. I’ll go over the difference between the standard N54B30 and the N54B30TO that was used in the 1 Series M Coupe and Z4 sDrive35is.

N54B30

  1. HPFP

Let’s start with the stand N54B30 engine. The biggest and most common issue that has haunted the BMW N54 engine since the start is the HPFP going bad and preventing the engine from starting, sometimes stuttering, misfiring or running well in general. It was such a big issue that BMW has extended the warranty on these to 10 years and 120,000 miles in the United States. The good part here is that most of the cars have already had the pump replaced with a revised version while under warranty.

  • Water Pump

Another big common problem on the N54 engine is the electric water pump that uses some plastic parts. These fail unexpectedly and usually at the worst time! I’ve had 2 OEM water pumps fail on me when I had the car. I got the yellow triangle saying that the engine is running hot and within 2 minutes a red triangle with a message saying to drive moderately and to shut off the engine as it has overheating. Unlike the HPFP, there is no extended warranty or anything like that and unfortunately, the pump is very difficult to get to. I paid around a $1000 each time it failed in Chicago. The pump is about $400 and labor is at least that much again.

  • Fuel Injectors leaking, Ignition Coils

These engines also suffer from leaky injectors. BMW N54 uses direct injection and these must be very precise for the engine to run correctly. Unfortunately, when they start leaking which  can cause many different problems including hard to start engine once warmed up, rough idle and misfires as well as terrible fuel economy among other issues. Of course, some of these symptoms can be caused by a bad spark plug or coil and I would definitely recommend replacing those before touching the injectors as each injector is about $250.

  • Turbochargers/wastegate rattle – people upgrade them for more power

Next issue that’s common on many BMW engines including the N54 is the wastegate rattle. Early on, this isn’t a huge issue as it mostly just makes a rattling noise on start up, it gets worse and worse over time. Eventually, the wastegate flapper starts leaking boost and causing performance issues. If not taken care of at this stage, the ECU will try to compensate for the lack of boost potentially overheating and destroying the turbocharger and maybe even the engine if metal gets into the intake. In addition to the wastegate rattle issue, turbo seals can fail and cause smoke out of the exhaust. These issues are more common on tuned or hard driven cars. Small piece of advice here is to not punch it hard until the engine is fully warmed up and to let the engine idle for a little while after driving hard before shutting off the car. [explain why let it idle][Aftermarket upgrades are very popular.]

  • Leaks become more common once getting closer to 100k

If you have watched my BMW N20 engine video [link it], this will sound very familiar. There are a few oil leaks to watch out for and the most common one is the valve cover oil leak. Usually, the plastic valve cover will crack and start leaking. Sometimes the gasket goes bad as well and the entire cover should be replaced. It’s important to get this done quickly as it would be leaking on the exhaust manifold, turbos and the O2 sensors. The oil filter housing gasket is also prone to leaking and should be replaced ASAP as it will leak oil onto the serpentine belt and can cause all kinds of problems. Oil pan leaks are less common, but possible.

  • Chargepipe

The next common issue on these engines is the chargepipe that cracks over time. BMW used a plastic pipe between the intercooler and the intake manifold which runs under boost a lot of times and of course becomes brittle and eventually fails. I’ve had this fail on my N55 [n55] engine as it uses the same design and replaced it with an aftermarket one that works much better. This is an easy and inexpensive fix to a common problem.

  • Minor items:

There are of course many other little issues with these engines that you may need to take care of over time, such as the starters going bad out of no where [link N20 video] or VANOS solenoids causing loss of power, engine hesitation, rough idle and decreased fuel economy. I have actually made a video on how to test and clean these if you’re interested and they are a decently simple DIY. Carbon build up is another issue that shows up on many lists, but that’s common on most direct injected engine and not BMW or this engine specific.

N54B30TO

As I mentioned earlier, N54B30TO was the more powerful version of the N54 engine making 335HP, but this was achieved mostly by adding a performance power kit tune and some supporting cooling hardware. [list: upgraded fan, radiator hoses, secondary radiator, oil cooler]. So, the engine itself was the same but with just a little more boost. This also means that all problems we have discussed so far are also present on this version of the engine as well.

Best and Worst Years:

Now 15 years after it has been released and after so many problems, should you even be looking at buying one? Luckily, this engine has had somewhat of a cult following lately and is becoming sought after in the tuner’s world. This also means that most people are trying to preserve it and maintain it properly. Additionally, issues like the HPFP and injectors have been resolved from the dealer and mostly done under warranty. Most other issues have been figured out in the aftermarket world with the upgraded turbochargers to get rid of the wastergate rattle and metal chargepipes to prevent boost leaks. One word of advice, avoid getting an already tuned engine if you plan on dailying your ride. [notes on why not]

Personal Experience:

A quick note on my personal experience with the engine. Over the period of 4 years and about 55,000 miles, I had to replace the spark plugs, ignition coils and 2 water pumps and nothing else. In every video I’ve made about the BMW engines I’ve owned, people tell me I just got lucky and that may be true, but it doesn’t hurt to properly take care of these engines as well.

Conclusion:

In conclusion, remember that this is an aging BMW motor that was packed with top-of-the-line technology and most likely driven hard by the last owners, so be ready to spend a little bit of money on maintaining it properly. It’s a wonderful, powerful and still one of the more reliable engines made by BMW with lots of aftermarket support and capability to produce tremendous power!

BMW N63 Problems to Expect – Reliability Report

Hey guys and welcome back to the SimpleCarGuy channel. BMW N63 is a twin turbo V8 engine that has been powering fast BMWs for over a decade and today we will talk about the common issues, technical updates, best and worst years to buy and my 4-year experience with the engine.

History

The BMW N63 replaced the naturally aspirated N62 V8 engine and had many improvements over the years. It was also the first hot-V layout, first direct injected and first turbocharged V8 engine from BMW.

This engine begun production in 2008 and is still being used in many BMW vehicles. Of course, over the years there were 3 technical updates creating 4 different versions of the engine, adding more horsepower and torque, improving reliability and making a better engine overall. There are lots of forum posts and groups discussing different issues on different version of the engine and it can be a little difficult to keep up. I have sorted through most of this information over the 4 years I had this engine in my BMW 550i and organized it in this video. I will explain the difference between each version and what was updated as well as what BMW models the specific version of the engine was used in. Let’s get to it!

BMW N63

The original N63 engine was first used in the E71 X6 and produced 402 HP and 443lb ft of torque and later used in the 550i, 750i, X5 and X6 between 2008 and 2013 with the exception of the 650i where it was used from 2012 to 2017.

Common Issues:

If you have heard horror stories about the N63 engine, it was probably about this version of the engine, but there are a few common issues across the entire run. To start with, most of these engines will burn some oil. This original version will do so excessively and it’s important to make sure you never run low. In addition to burning oil, the timing chain is a weak point on these and becomes an issue at higher mileage. As soon as you can hear any chain rattle, it should be replaced as soon as possible. Another common failure on this engine was the HPFP and injectors which caused the engine to stutter, lose power and run very rough in most cases. On top of these, there were also issues with mass air flow sensors, vacuum pump, low pressure fuel sensor, turbo seals and crankcase ventilation lines.

Obviously, that is a huge list of common problems on these original BMW N63 engines, but luckily BMW took ownership of the problem and issued a voluntary recall called the Customer Care Package where they revised the service internal from 15,000 to 10,000 miles and fixed or replaced any issues related to the timing chain, fuel system, battery, vacuum pump, crankcase vent lines and more! This helped many owners at the time and prevented many unhappy owners in the future. If you are looking at a BMW with this engine [show cars again], check that this service has been performed or the items have been serviced individually. This is a must.

BMW N63TU

Clearly that was a lot and BMW realized that they had some major issues they needed to fix here and that’s what they did. In 2012, they have redesigned most of the engine in the Technical Update 1. The new engine was now known as the N63TU and it got an updated timing chain, forged rods and crank, new pistons, turbos, injectors and HPFP. On top of that, they changed the VANOS system to the one used on the N55 engine and updated the crankcase ventilation on a new valve cover among many other things. Not only did all of these changes make a huge difference in reliability, it also added 42 more HP and 37 lb ft of torque. This engine was used in the same range of cars as the previous version. [list on the screen]

Common Issues:

That’s a lot of changes, but did any of this help? Actually, YES! The BMW N63tu is a much more reliable engine, but being a typical BMW, it still has its common issues. Oil consumption is typical if thinner oils are used or not changed as often and it can burn a quart of oil between changes, but if you see some smoke out of the tail pipes, it could be much worse as it could be an indicator that the valve seals need to be replaced. My friend had this happen at 35k miles, but the dealer covered it completely. As per BMW, the engine has to be pulled out of the car to do this job and it can get very, very expensive if out of warranty. Of course, there are other minor issues that can creep up on this engine, but nothing too excessive. I’ve seen reports of leaking   here and there but nothing engine destructive. A much better and more reliable engine.

BMW N63TU2

Next update came in 2016 and the biggest change this time was switching to twin-scroll turbochargers giving the engine a wider powerband. Other changes were mostly there to support the turbo upgrade and to optimize the engine. The stock power levels remained the same and so did the reliability. This engine was used in the 750i as well as the M550i between 2016 and 2020. [list on the screen]

Common Issues:

Luckily these changes have made the N63TU2 engine even more reliable with not many common problems. The oil consumption has been reduced and if you change your oil every 7000 miles, you shouldn’t have these issues. A couple problems I’ve seen come up from time to time were leaky coolant lines as well as issues with intercoolers which were covered by a service bulletin from BMW. Overall, a very solid engine.

BMW N63TU3

The last version of the BMW n63 engine is the N63TU3 which is once again used in the top-of-the-line versions of each series. There is a lower powered version making 456hp and 479lb ft that’s used in the regular X5 and X7. This engine received a new ignition system and improved thermal shielding for the crankcase and cylinder head and even forged rods from the S63 engine. The valve stems have been updated as well. The more powerful version of the N63TU3 is used in the M versions of the 5, 7 and 8 series as well as X5, X6 and X7 SUVs. [but not actual M5, M7, M8 etc] It includes all of the updates already mentioned as well as larger turbochargers, different ignition system, rebalanced crankshaft with new main bearing shells, piston skirt coating and electric arc wire sprayed cylinder walls. All of these upgrades result in massive power gains making 523 HP and 553lb ft of torque and it’s not even an S63 motor.

Common Issues:

There isn’t too much information on these engines as far as reliability just yet as they are still fairly new, but since the valve stems have been upgraded among many other things, the engines seem to no longer burn oil even with hard driving. Overall, the N63TU3 is the most reliable and most powerful N63 engine with a decade of improvements and upgrades.

Best and Worst Years:

So, what are the best and worst years to buy a BMW with the N63 engine? In my opinion, unless you are willing to deal with the issues or they have already been completely taken care of, I would skip the original N63 engine cars and go for 2014 or newer models to be safe. [put list of years when switched]. Of course, if you got the cash, the latest N63TU3 is a beast and makes for a very fun driving car with no reliability issues but will cost a pretty penny. [Driving X6M] I think that N63TU and N63TU2 are a bargain at the moment with decent reliability and power figures and that’s the ones I would go for.

Personal Experience:

As I mentioned earlier, I owned a 2014 BMW 550i for over 4 years, so I had the N63TU engine and I have to say, it was VERY reliable for ME. In all of that time, all I have had to do was change the ignition coils and spark plugs around 60k miles and of course changed the oil every 5k miles! This is very important to keep these running smoothly.

Conclusion:

In conclusion, this engine gets a bad rap based on the early years, but many issues have been fixed on the second iteration of the engine and further perfected over the years. I wouldn’t hesitate to own another N63 powered BMW as long as it’s 2014 or newer and has been taken care of properly over the years. A healthy BMW N63 provides a very powerful, fun, sporty and torque-y driving experience that’s hard to get anywhere else.

BMW R NineT Problems to Expect

Hey guys and welcome back to the SimpleCarGuy channel. As with all of my vehicles, I like to nerd out and do as much research as possible, so in this video we will talk about common issues on the BMW R Nine T.  Specifically, we will dive into the engine reliability, bike electronics, sensors and other components. I will also discuss preventative maintenance, what to pay attention to and my bike’s repair history as well.  

If you have this bike, check out another video I have made on this bike where I talk about its hidden features and thing you might not know!

Engine:

Let’s start with the air and oil cooled engine. Is it reliable, do they overheat and have other major issues? Well, since this retro bike uses almost a retro engine so most of the issues have been ironed out by now. The R NineT runs the BMW R1200 camhead engine which is the same engine that’s used in the R1200RT and R1200GS from around 2010 to 2015. Based on owner reports, a typical lifespan of this engine is at least 100k miles and many examples have reached over 200k miles without major engine work. Although not the same engine, BMW Boxer design has been evolving and being modernized for decades before it ever was put into the R NineT. From what I have read, they are low stressed, overengineered and extremely reliable.. if you take care of them.

Now, what is there to take care of on this engine? The main and most important thing to remember with this and many other BMW engines is the oil. You have to check the oil often and make sure it stays around 75% in the little window on the side of the bike. These bikes tend to burn oil for the first 10k miles so it’s recommended to check your oil every 500 miles or so. Some swear that it stops burning oil around 10,000 miles and some say it still burns, just much less oil. You can think of it as a break in period so I guess I have another 8000 miles to go! Since service is expensive on these just like any other BMW and you will have to top up oil at some point, make sure you DO NOT overfill it. Apparently, it’s very easy to overfill and when you do, you will blow your rear main seal in no time.

Some people think that since there is no coolant, the engine won’t be as reliable and will overheat. Generally, it would be fairly difficult to get one of these to overheat but if you live in the desert, it is possible. So, you have to treat them as air and oil cooled bikes; especially since there is no temperature gauge on the early models. Luckily, they are equipped with a thermal shut off so at least the bike will not burn itself down. Starting 2017, they do have a temp gauge and a temp warning idiot light, but it’s not always accurate and can be deceiving. Why is it deceiving? Well, the temperature is read at the cylinder so it’s much higher than anything you’d ever see on a temp gauge on a car. On top of that, the max on the gauge is 143C/289F which isn’t actually the temp where it will overheat. It can go even higher before the warning light and the automatic shut off after that. Anyway, as you can see, it’s a bit confusing, but luckily not something one has to generally worry about. Just keep the bike moving and don’t get stuck in a traffic jam where you sit for 30+ minutes idling in 100 degree heat!

To summarize, this air-cooled boxer motor is a thoroughly tried and tested unit and has been powering boxer range BMW for years, so engine reliability is not really a concern on the R NineT, but do service it regularly like any other BMW. We will talk about some preventative items we can do, later in the video.

Electronics:

Next, let’s talk about electronics. As this is a retro styled bike, the R NineT isn’t on the very leading edge of technology like many other BMW bikes. It has a basic suspension, ABS and traction control as an option and not a lot of gadgets in general. That’s a good thing in m y opinion as there are way less things to go wrong with and it also means this bike can be a keeper for years to come. However, there is one issue that I have seen come up on multiple forums and group. The ABS Sensor. It seems that a lot of people have experienced issues with the ABS sensor going bad which of course disables your ABS and traction control, but also causes the speedometer and odometer to stop working. This is an issue that has been carried over from the GS crowed as it uses the same design. Some of the older models have also had a problem with the wiring loom to the headlights where the wires would run when while moving and eventually fail. BMW has fixed this issue on the 2017+ models with a plastic sheath, so it might be a good item to look into if you have an older bike like I do.

Those with closer to 100k miles should watch out for fuel pump issues and the mail seal failure, but these are not very common.

Other Issues:

Speaking of not very common, let’s talk about other issues or concerns that people have with the bikes that may not necessarily have to do with the engine or the electronics system. One of the biggest complaints on this motorcycle has to be the quality of the seat and suspension. Some say that it’s basically unusable in the stock form for long distances and I have to agree to a certain extent. I’m not a long-distance rider, the most I’ve done at the same time was about 3 hours and I did have to stretch a couple of times to prevent being sore in the back. From what I’ve read, it’s more pronounced with bigger riders and some choose to upgrade. A very good quality, thicker seat can be had for around $500 and the same for a good rear shock as well. Most likely a worthy upgrade if you want to do long distance on the bike.

I also wanted to mentioned the transmission on this bike. Luckily it doesn’t nee it’s own section. Even though it’s a little agricultural in its feel, the transmission is solid and there should be no issues with it for the life of the bike. The only major worry would if the clutch starts slipping, it becomes a major job as the engine has to be split in half. Luckily, the only reports on this are well over 100k miles.

The R NineT also has spoked wheels on some models and that means it has tubes in its tires, this isn’t necessarily an issue, but you can’t fix a flat with a kit or anything like that. I’m not sure I would be comfortable riding on a kit fixed tire, but people have complained about it. This also means that you have to be really on top of checking air in your tires and making sure it’s correct as you can cause problems with the valve stem on hard acceleration with low air pressure. The bikes also handles horrible with about 25 psi in the tires.. just from my personal experience.

This bike can also go through rear brake pads pretty quick if you tend to use the rear brake more than the superior front brakes, but that’s more of a preventative maintenance item.

Preventative Maintenance (and what to pay attention to):

Other than regular oil changes, what else should we look out for on these bikes? Well, of course you should be keeping up with the scheduled items in your manual like the transmission oil, final drive oil, brake fluid flushes **ADD ITEMS FROM MANUAL HERE**. Some people go by the book and some choose to change the fluids every time they put on a new tire. Some also recommend lubricating the transmission shaft splines very 40k or so and getting the valve clearance checked at 12k miles.

If you store your bike over winter, there are a few things to do as well. First of all, get yourself a battery tender, it’s much cheaper than buying and replacing a new battery in the spring. To keep the tires from squaring off, some people overinflate them slightly or ideally you can get a motorcycle stand and lift the wheels of the ground. It’s also a good idea to fill the tank and add a fuel stabilizer on the last ride of the season. This way no condensation builds up and she will fire up like nothing happened in the spring.

Personal Experience:

So, what has my experience been like with the bike. I’ve owned my bike for one full summer at this point and put on half of its 2000 miles. I had to do absolutely nothing but fill it up with premium gas, ride it and smile every time I open the garage door. However, I did receive a small packet of papers with the bike. Let’s take a look at those now. *Show pictures of maintenance done on the bike before I got it.*

I have realized a couple of items for myself since buying the bike. What you see on forums and groups can be slightly misleading as this is a premium brand and product and people have really high expectations. You have to enjoy this bike for what it is, an awesome retro styled roadster. Of course, I’m not afraid to work on my own vehicles anyway so that doesn’t scare me at all.

In general, there really shouldn’t be any issues with the BMW R NineT as it’s mostly gadget free with a drivetrain and engine that have been in the lineup for over a decade in some form or another. Most people, just like myself have had a wonderful experience with the bike, but I think it’s good to look at the bad sometimes and be prepared and on top of things. I’m generally very happy to have experienced the freedom of the open road, the exhilaration of riding on twisties and just cruising behind the bard on this gorgeous bike. Every time I pull up to another motorcycle, I get the same feeling, I’m riding a beautiful machine, a rolling piece of art that meant to be ridden hard! I’m willing to put up with any issues it presents for this experience and I hope you feel the same about yours. If you are looking to buy one, don’t hesitate, go for it and worst comes to worst, you’ll have to get your hands dirty wrenching on a cool bike.  On that note, thank you guys so much for watching, leave your comments and thought below, like the video if you like it and I’ll see you in the next one.

BMW X5 Problems to Expect – BMW F15

BMW X5 Problems to Expect

Hey guys and welcome back to another video on the SimpleCarGuy channel. Today, we will look into some common problems you can expect on the 3rd generation BMW X5 which is also known as the F15. We’ll discuss the best year AND model to buy if your main concern is reliability and which version to avoid, if any.

In this generation there were a few different versions of the car. There was the BMW 35i that came in RWD as well as AWD configuration and had the same N55 engine. The more powerful version of the X5 was the xDrive50i powered by the N63 engine which is what this car has as well as my BMW 550i, so I’m pretty familiar with this one. The last version was the xDrive 40e with the N20 engine combined with a hybrid system. I don’t know much about the diesels or the X5M, so I will not be talking about those versions here.

Before we continue, don’t forget to hit that like button for YouTube Algorithm and leave a comment letting me know which version you’d want to own.

Now let’s talk about some common issues across the range that are not dependent on the engine. We will get into the engines shortly. Of course, each car is different and even though some of these are common issues, they may never happen to your car, but then again you can easily have multiple issues I talk about here as well, even if you take good care of your car.

The most common issue people have reported is leather cracking on the side of the seat. Just something to look out for as it can cost a decent amount to repair if you’re out of warranty.

Another commonly reported issue is squeaks coming out of the steering column as well as the rattles from the tailgate when driving on rougher terrain and wind blowing through the driver’s door seals at high speeds. The latter one can be fixed with a simple door adjustment, but still something to be aware of.

A little less common, but some X5 cars will have water leaking from the drain tubes in the sunroof after a heavy rain or car wash. If you are looking to buy a BMW X5, check the roof liner and the rest of the interior to make sure there is no water damage.

If car has rear air suspension, the bags can develop little pin holes or leak air in other ways as well. Not only will the car sag after sitting for some time, but that also means the compressor will have to work overtime and can fail prematurely. A lot of them come with springs, but if you have the 3rd row seats, there is a chance you have air suspension.

I have also seen a lot of people reporting issues with the car not shutting down on the first press of the start/stop button, this isn’t something you can fix at home and a dealer visit is required.

BMW xDrive35i/sDrive35i (2013-2018) N55:

Now let’s break it down to specific models. We’ll start with the BMW sDrive35i and the xDrive35i that were available from 2013-2018. The difference between the two is that the xDrive version is of course all wheel drive. These cars come with the n55 engine and I’ll start by saying that this will be the most reliable engine you can get in this car. Does this mean you won’t have any issues? Of course not, but luckily BMW had pretty much figured out the N55 engine by 2013 and any issues they had in the early years were mostly solved. Most notably the rod bearing issues that the early n55 engines suffered from have been taken care of. If you’d like to see what kind of damage that can cause, check out my BMW N55 engine rebuild series!

Some issues you CAN expect to have on these N55 engines would be the oil filter housing gasket leak, which in itself isn’t that big of a deal, but if the oil goes onto your serpentine belt, it can cause all kinds of issues. It’s best to replace it as soon as there is any noticeable seepage.

Another issue that seems to be common and not fixed by BMW is the plastic charge pipe that can crack and cause boost issues. It’s a very popular upgrade for anyone with the N55 engine, even if they are not seeking more power or thinking of tuning.

BMW xDrive50i (2013-2018) N63TU:

Next let’s take a look at the xDrive50i with the n63tu engine produced between 2013 and 2018. This is the car we have here and of course the most fun out of the bunch with lots of power to play with. If you Google issues on the N63 engine, you will get a list long enough to make you cry, but luckily, most of those posts are about the original N63 engine which is not what this car has. The X5 has the updated version, the n63TU, which is a very important distinction. Not only does it have 40 more horse power, but it’s also much more reliable and does not suffer from the same issues.

I’ve done a lot of research on this engine as I have the exact same engine in my BMW 550i and all things considered, this is a pretty reliable twin turbo V8. Personally, I have not had any issues with the engine and I’ve only had to replace the ignition coils and spark plugs on mine. The owner of this X5 has also had to replace a couple ignition coils as the engine was misfiring.

Oil consumption is normal if thinner oils are used or not changed as often, but if you see some smoke out of the tail pipes, it could be much worse. This X5 has had its Valve seals replaced at just (See miles) miles. That’s a VERY expensive, over $10k, job from the dealer, that luckily for this owner was done under warranty. If you go with an indy shop, it can cost as much as $5000 to do.

Of course, there are other minor issues that can creep up on this engine, but nothing too excessive. I’ve seen reports of leaking oil pump gaskets, oil pan gaskets and maybe a head gasket leak here and there but nothing engine destructive. I recommend this engine if you like power and luxury all built into one car.

BMW xDrive40e (2015-2018) N20 Hybrid Combo:

The last model we will take a quick look at is the xDrive40e that was available from 2015 to 2018 and is using a hybrid combo system with the n20 engine. This is heaviest of the bunch and the most complex out of the X5s. While it’s using the updated n20 engine, these are known for timing chain and timing chain tensioner issues as well as rod bearing issues. I’m sure this engine is not very stressed with the help of the hybrid system, but it is a very complex vehicle. The only consistent issue I saw people complain about is the issue with charging at home where it fails to initiate randomly.

Conclusion:

While BMW’s X5 is a very fun SUV that provides luxury and sportiness and is overall a great package, just like any other BMW, there are some problems to expect and I hope this video has helped you make a better decision or prepared you for ownership. So, which model should you go with? As far as reliability, I would say the sDrive35i with the n55 engine will most likely give you the least amount of trouble, but the xDrive50i with the n63tu engine is not a bad buy either and a lot more fun to drive. I would avoid the xDrive40e due to complexity and the less reliable N20 engine. The production year difference is pretty much negligible as there were no updates through the production run.
