You’ve heard the rumour and it’s so strong that it’s caused you to think twice about investing in a BMW: BMW – in spite of their awesomeness – are unreliable.

BMW is one of the most sought-after premium brands in the world. Blending power and performance with sporty appeal, BMW are sophisticated, classy, and pretty much everything you would want in a car.

But, there is one mark against their reputation that they just can’t shake off; their reliability.

The question of reliability has haunted the prestigious brand – and German cars in general – for a while now, and one of the questions we get the most from customers when talking about BMW is ‘are they reliable?’

One of the biggest factors you should consider when getting a new car is whether it is reliable. If you can’t depend on your car, then it could cause you a major headache later on and end up costing you an eye-watering amount of money.

So is the “ultimate driving machine” a reliable car?

In this article, we’re going to look at whether BMW ‘s live up to their unreliable reputation and look at how they fare when compared to their competitors.

Is a BMW a Reliable Car?

Since 2007, BMW has not scored above average with Consumer Reports. In 2012, BMW 3 Series convertible topped a list of the five least reliable cars. The BMW 5 Series came third in that list. Not only that, but their research found that cars aged between four and eight years old are more likely than any other car to be off the road, with the 3 Series being the likeliest car to be so. Back in 2010, Consumer Reports Best Cars study placed BMW as one of the least reliable in most of the classes and categories.

So far, so unreliable.

But, that was a while ago, where does it rank now?

Well, according to J.D. Power, BMW is still…average. The only category it was classed as above average was Body and Interior Dependability. In J.D Power’s 2015 U.S Vehicle Dependability Study, BMW have 146 problems per 100 vehicles, putting them above average.

However, because J.D Power is based on consumer surveys, BMW have often been ranked lower for trivial reasons. For example, one of the points of dissatisfaction has been, in the past, down to BMW not having cup holders. So consumer surveys should be taken with a pinch of salt.

Why Are BMW’s Unreliable?

We’ve established that BMW’s are pretty unreliable but, why?

Consumer Reports have said that BMW, as well as their fellow German brands, put all their focus on performance. This can come at a cost to reliability.

Gabriel Shenhar, automotive engineer at Consumer Reports, said that “They are susceptible to cost-cutting anywhere they can in the hope that the customer won’t know, they use suppliers that will deliver and sometimes they won’t.”

Shenhar points out that a common gripe people have with BMW is that they are sometimes guilty of using plastics instead of more durable materials. Another common complaint is that the complex electronics BMW implement in their models are prone to breaking down.

These “complex electronics” are worth expanding on. While BMW engine’s are often fine and problem-free, the electronics – what we can call the little stuff – are full of gremlins.

Then there are common, niggling issues, such as a driver’s side door handle, door locks and window regulators. In the past, these have been cited by frustrated drivers as breaking down.

But Are BMW’s Actually unreliable … Or Do We Just Not Maintain Them Properly?

This is the key question for some, but it’s kinda misleading.

People will point out that a BMW is a premium car, and therefore it needs proper maintenance. This means that you need to take good care of it as though it was your baby.

You need to get the oil changes done at a certain time, and you have to use the right oil. If you don’t, things can go wrong. If you keep on top of its maintenance, a BMW can  theoretically last a long time – perhaps forever.

That’s true of its engine. But as we’ve pointed out, it’s the little stuff that can often bring a BMW down. And it’s this that frustrates buyers and which contributes to its reputation as an unreliable car maker.

The good news? If you maintain your BMW properly, any other unreliability issues won’t cost  you a fortune to fix.

How Did BMW Rank In Other Areas?

The J.D. Power Ratings put BMW at the top for Quality Overall and above average for Performance and Design.

So, while their dependability can let them down, people are pretty pleased with the car itself.

BMW Vs. Audi Vs. Mercedes-Benz: Which One Is More Reliable?

So, how does the beloved BMW fare against its German counterparts, Audi and Mercedes?

Not very well, actually. In terms of dependability, both Audi and Mercedes scored higher than BMW, achieving above average. Though they all ranked the same in terms of overall performance and design.

However, it was in overall quality that the BMW shone, overshadowing both Audi and Mercedes with the highest ranking.

Which BMW’s Are the Most Reliable?

While BMW’s are generally average in terms of reliability, there are some that score higher than the rest.

It should be noted that the following list is based on ‘predicted reliability’, and the BMW’s that are predicted to be the most reliable are;

  • 2016 BMW X3
  • 2016 BMW X1
  • 2011 BMW X3

The 2011 BMW X3 actually scored five out of five, with J.D. Power classing it as ‘Among the Best’.

Which BMW’s Are the Least Reliable?

While there are above average BMW’s, there are also below average BMW’s. Again, this is based on predicted reliability, but the BMW’s that are predicted to be the least reliable are;

  • 2012 BMW 3 Series
  • 2016 BMW 3 Series
  • 2009 BMW 5 Series

Ultimately, BMW aren’t necessarily considered the most reliable car on the market. But they are still loved by many, and their overall score shows that the design, quality, and performance offsets the fact that they aren’t the most dependable car on the market.  You can check out our BMW page for the latest in depth reviews.

    I am retired and hoping to leave London and return to my roots in the north west next year. I’m not a millionaire but by trading down on my house I might have around £200,000 to spare. I set my heart on the BMW 840d. That would be around £85k with extras. At that price I expect whatever I buy to be utterly reliable, like those Mercs from the sixties you read about that are still running with half a million miles. OK, I won’t live long enough to see that but I do not want to end up taking out a mortgage to keep the car running. What I have read here has left me rather shaken. Perhaps a Lexus would be the better choice, in fact I know it would be, but I hate the front view of their cars. Do BMW sell extended warranties, way beyond the first three years? Otherwise it’s goodbye to my dream.

    I own a 2008 black on black 550 woth the m5 wheels. I love the looks of this car as wll as how it handles and performs. Even though i have babied this car it has been nothing but a money pit. From the engine beig on…to motor mounts busted…blue smoke coming out of the exhaust…several engine leaks…vacuum pump replacement etc etc…i do not recommend a bmw to anyone. The other day a saw a brand new bnw 750 …a $100,000 car with blue smoke coming out of the exhaust. Either German engineers dont know what they are doing or they purposley design the cars to fail so they can make millions on replacement parts and service.

    I have a 2002 330i, which admittedly is quite elderly. It’s true though; I have had literally a ton of problems with this car. The problems I’ve had primarily stem from the cooling system, which as mentioned, has a lot of parts made from plastic. The plastic gets brittle over time and cracks, meaning I’ve had numerous coolant leaks to deal with. Other than continuous cooling problems, they’ve all been electrical. My alternator cooked my battery which created a terrible smell, the outside temperature sensor use to short in the rain, resulting in the car thinking it was -40° outside and turning the A/C off when it was 90° outside (gotta love Florida). If I didn’t have the means or know-how to do all of this work myself, this car would have been long gone. I’m able to afford it because I can fix things, which is why I can confirm the accuracy of this article. The problems I’ve encountered are either electrical, or caused by plastic being used in place of where metal obviously should have been. The upside is that BMWs are truly the ultimate driving machines. I have zero regrets about spending money if it means I get to drive it again. Plus it’s true what the article says about the engine. At 162,000 miles, the engine has been flawless. I bought the car from the original owner, my aunt, at 125,000 miles. Since I therefore know it’s history, I can confirm that if you keep the oil changed the engine will last forever. But probably not much else.

      Hi Eamon,
      Thank you for your comment. Information like this is always really useful, especially for people who are looking at a specific model and want to find out more about it. I do not envy you the issues with the temperature sensor given your climate. I wish you continued luck with your car.

    I have a 2011 X5 35d. I want to call it the best SUV on the road. It’s beautiful, drives great, and helps get me and my toys to the mountains. However, at only 66,000 I have had the entire SCR tank replaced, a fuel injector replaced, 3 alternators, and now another undiagnosed issue. In addition, my rear cam malfunctions in hot conditions. I want to sell it but it won’t run long enough to sell it privately in good conscience. I keep up with all maintenance at the local BMW dealerships. What is most telling is that the head foreman at BMW dealerships as well as other BMW technicians refuse to stand behind the vehicle and suggest I sell it.

      Hi HB,
      Sorry to hear that you’ve had issues with a car that you enjoy the experience of driving. I hope that you are able to find a vehicle which has all the features that you clearly love about this one which doesn’t suffer the same glitches.

    Serial short-term BMW owner here. I’ve leased two (330ZHP, 330i) and financed two (335d which I sold at year 5) and current 435i which is over 4 yrs old.
    The E46 330ZHP was fun to drive but I had an oil sensor issue and the subsequent owner had to have the transmission mount replaced at 45k miles.
    The E90 330 had to have the cylinder head replaced because of the ridiculous valve tap. Thankfully that was under warranty.
    The E90 335d, I bought an extended warranty which came in useful. During year 4 the vehicle, on and off, was in the shop because the DEF system was not functioning correctly. Over the course of 10 months I had the entire SCR system replaced as well as all the sensors. It was a fantastic drive.

    The 435i. Well this one has been problem free. The N55 has been very reliable and BMW shortened the OCI to 10k miles starting around 2012 or so. I WANT to keep this car, I love the way it drives but I’m scared to death of owning it without a warranty so regrettably I have to sell it. For the past 6 months I’ve hardly driven it so I can keep the miles down and help with resale.

      Hi JC,
      It certainly sounds as though you are a very loyal BMW owner, with that many in your car history. I hope that you can find another one you enjoy as much as the 435i you are currently carefully driving.
