Are BMWs Reliable? Reasons for Their Reliability
Are BMWs reliable? It’s a question that is asked countless times. And the truth is there’s no easy answer. You’ll find examples of notoriously problematic BMWs that have a trouble-free background. At the same time, it’s not hard to come across supposedly reliable BMW models that are headache-inducing nightmares.
So, the easiest way to approach the “are BMWs reliable” question is to favor the odds, an essential strategy if you’re shopping for a used BMW. In other words, look for BMWs that are least likely to have problems. This involves a two-step process of checking an individual car’s history and looking at specific models with a generally good reputation for reliability. We’ll first review what’s involved with checking a car’s background and then dive into some suggestions for reliable BMW models.

Individual Car History: What To Look For
The first step in considering any used BMW is learning about its history. The good news is that services like CARFAX and AutoCheck can help you spot any red flags, such as accidents, a salvaged vehicle title, or a discrepancy with odometer information. This information isn’t perfect, but it goes a long way in helping you weed out potential problems at the beginning.
Next, look for ownership history. The idea here is that the fewer owners, the better, with the holy grail being a single-owner BMW. A one-owner car is more likely to have been well-maintained and pampered. On the contrary, a six-year-old BMW with three owners indicates something may be wrong with the vehicle. A vehicle history report usually will have ownership details.
Additionally, review the vehicle’s maintenance records whenever possible. The CARFAX or AutoCheck report may have these specifics, but it’s not unusual for a BMW owner to have this information trail. For more than 25 years, new BMWs have received up to four years of free factory maintenance, so the paperwork may begin here. Even subsequent owners may keep service records to confirm routine work and repairs. Any mechanic will tell you that regular maintenance and the evidence to prove it are preferred traits for a used car.
NOT JUST FOR CAR SHOPPING
The CoPilot app isn’t just for buying a car - our new CoPilot for Owning tool will help you keep track of recalls and gives you advice on which scheduled maintenance tasks are most important.
Notably, service records will help confirm if the BMW you’re considering (or any car) has been repaired under any manufacturer recall (which can also be reviewed in an NHTSA database). What government records won’t tell you, service reports will if the vehicle has ever been worked on under an automaker’s technical service bulletin (TSB). Often called a hidden or secret recall, a TSB is a manufacturer’s way of advising service shops that a car may have a specific problem. However, the problem isn’t sufficiently widespread to warrant a full recall. Further, an ignored TSB can lead to more mechanical troubles caused by an uncorrected system or failed component. It all goes back to proper maintenance.
Lastly, always have a prospective BMW inspected by a professional mechanic who can look beyond history reports and repair records. A mechanic can check for unreported damage, confirm if recalls and TSB repairs have been fixed, and look for potential problem areas. For $100-$200, a pre-purchase inspection is cheap peace of mind.
Most Reliable BMW Models
Here’s a brief overview of some BMW models that get good marks for reliability from enthusiasts, car reliability websites, and related resources. Remember that just because a particular BMW model is on this list, don’t assume that every one of these cars will be perfect and trouble-free. Be sure to follow the abovementioned steps as you ask, “are BMWs reliable?”
2002 to 2008 BMW 7 Series
While BMW’s largest sedan, the 7-Series, is often the first to receive the company’s latest technological advances and accompanying headaches, 2002-2008 get a reliability thumbs up. While the fourth generation can be found with a powerful 12-cylinder engine, skip the temptation and stick with still-decent 8-cylinder power. Not only will you save on gas, but repairs (if they happen) will be less wallet-draining. The most frequently reported problem for this car is coolant system issues, so check repair records to see if this has ever occurred.
THE BEST USED LUXURY CARS ON THE MARKET
Buying a used or CPO luxury car is one of the smartest buys you can make - you can get a lot of car for not much money. You can pick up a three-year-old luxury car for about half of what you’d pay new. Check out this list of the best used luxury cars on the market to find the best deals.
2008-2010 BMW X3
The first-generation BMW X3 may not be as sleek and stylish as current SUVs in the automaker’s lineup, but it gets good grades for staying out of the repair shop. We suggest bypassing the model’s first few years (2003-2005) to avoid “teething problems” that appeared in early X3s. The X3 received a new engine in 2006, so we recommend moving ahead to the 2008-2010 editions. These newer X3s avoid the engine time chain problem that occasionally pops up with ’07 models.
2006-2011 BMW 3 Series
Used BMW 3 Series enjoys an almost cult-like following among enthusiasts. High up on this list is the 2006-2011 models. Available in sedan, coupe, wagon, and convertible forms, these spirited compacts enjoy BMW’s legendary driving dynamics and a rock-solid reputation for reliability. Look for the 325i, 328i, or 330i models. These skip the turbocharger and avoid the engine problems that can plague the more powerful 335i (and its twin-turbo 3.0-liter six-cylinder engine). Remember a simple rule when buying a used BMW. When given a choice, always select the model with less complicated components. There’s less to go wrong.
2008-2011 BMW 1 Series
As we discussed, when it comes to BMWs, less is more. And the short-lived (in the U.S.) 1 Series is a perfect example. Available as either a 128i or 135i (in either coupe or convertible form), these smallest Bimmers were all about simplicity. Rear-wheel drive is the only configuration, and the rear seats are barely usable. The trade-off is reliability and an authentic BMW driving experience that will put a smile on your face. The 135i does have a twin-turbo six-cylinder, so consider the non-turbo six found in the 128i.
THE BEST USED SUVS UNDER $10,000
We looked into price, reliability, features, and more to create this list of the best used SUVs under $10k on the market today. Take a look - some of the best used SUVs have gone mostly overlooked or forgotten.
2004 to 2010 BMW 5-Series
The last example in our “Are BMWs Reliable” review is the 2004-2010 BMW 5 Series, the brand’s mid-tier sedan. The bulbous exterior may appear dated by today’s standards, but the advantage is a larger four-door without too much bad history. As tempting as it might be, skip the models with the eight-cylinder or twin-turbo six-cylinder engines. Focus on the 525i or 530i, which have the simpler inline six-cylinder engine.
Common BMW Problems
BMW vehicles are known for their style, elegance, performance, and comfort. However, they’re not without their fair share of issues. Below are some of the most common problems you’ll likely encounter as a BMW owner.
- Engine cooling system issues: Overheating is among the many common complaints BMW owners have for their vehicles. Several causes can contribute to overheating, such as coolant leaks or a faulty water pump.
- Discharging batteries: Most BMW batteries will last from 4 to 6 years. However, several reports claimed that their BMW battery drained instantly overnight. Like many issues, there are numerous potential causes. In this case, it’s likely issues with the electronics, like accidentally leaving the lights on.
- Steering wheel vibrations: While this issue was reported in many BMW models, this one seems to be more common with the 3 Series. Frustrated owners claimed to experience excessive steering wheel shaking or vibrations, especially while braking. The likely culprit may be one of the thrush arm bushings.
- Malfunctioning automatic headlights: Numerous reports stated that their BMW’s automatic headlights stay on even when not needed. This unnecessarily drains the battery and may lead to electronic issues. A good rule of thumb is to contact a licensed BMW mechanic to fix this problem.
Frequently Asked Questions: BMW’s Reliability
Q: How reliable are BMW vehicles compared to other luxury brands?
A: BMWs are known for their performance and luxury, but regarding reliability, they tend to rank average or above average compared to other luxury brands.

Q: What should I consider before buying a used BMW?
A: When buying a used BMW, consider the vehicle’s maintenance history, mileage, and any previous repairs or issues. A pre-purchase inspection by a qualified mechanic is also highly recommended.
