BMW 3-Series Reliability through December 31, 2012

An asterisk (*) marks results based on small sample sizes.

General NotesModels and statistics marked with an asterisk (*) have very low sample sizes. These results, visible only to logged-in members, provide only a rough estimate of car reliability.

Any result under 20 repair trips per 100 cars is likely a result of the small sample size, and should be expected to increase to 20 or so in future updates.

New models often start out with high repair rates, and then improve as the manufacturer identifies and addresses common problems. MethodologyOnly successfully completed repairs are currently included in the analysis. Routine maintenance, most wear items, recalls, and problems fixed with just a reflash or warning light reset are not included.

What Our Members Are Saying about BMW 3-Series Reliability and Durability

Reliability and Durability of the BMW 3-Series: Pros
YearBody/PowertrainComment
2012 4dr Sedan turbocharged 240hp 2.0L I4
8-speed shiftable automatic RWD		 I traded in a 2005 BMW with 92,000 miles on it, if the realiability of the old one is any indication to the experience I hope to have with the 2012, then I have little to nothing to worry about.
2008 2dr Hardtop conv. turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD		 Have owned this car for 5 years; have had two replacement high pressure fuel pumps; replaced steering rack; new turbo gaskets (both turbos); replaced articulating hard top cables - all in the first 3 years and all under warranty! Nothing has gone wrong in the past two years so perhaps this was relatively new model growing pains.

2008 2dr Coupe 414-horsepower 4.0L V8

2006 4dr Sedan 255-horsepower 3.0L I6
6-speed shiftable automatic RWD		 No issues except the battery, but in the extreme Arizona heat, it is to be expected.
2006 4dr Sedan 215-horsepower 3.0L I6
6-speed shiftable automatic AWD		 After the warranty is over, beware !!
2005 4dr Sedan 184-horsepower 2.5L I6

2005 4dr Sedan 184-horsepower 2.5L I6
5-speed shiftable automatic RWD		 The car has over 50K and drives as if it were still new. No major issues have been experienced with this vehicle. It feels just as solid the day it left the showroom. The engine and trans

2003 4dr Wagon 184-horsepower 2.5L I6
5-speed manual RWD		 Car has had outstanding realiability considering its use daily in a four season climate. Parts are easly to get and inexpensive if you shop wisely. Many DYI resources on the net for regular service needs, and thus far most projects have been straightforward and easy.

5-speed manual RWD		 Its been rock solid so far
2002 2dr Coupe 333-horsepower 3.2L I6

5-speed shiftable automatic RWD		 Oil change every 15,000 miles. Reliability is top notch.

YearBody/PowertrainComment
2010 4dr Sedan 230-horsepower 3.0L I6
6-speed shiftable automatic AWD		 I'm a little nervous about repair costs and frequency. I keep reading about 4-figure repair bills, but there are others who say they've done well with just normal maintenance. Consumer Reports gives the 2010 328i a lot of red dots which is a goo
2009 2dr Coupe turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD		 Fuel pump, oil cooler, and run flat tire issues on the 335i turned me off. Will likely be covered by warranty, but met multiple people who had week long+ repairs for these issues. After warranty, 1,200+ for each of these issues is apparently common.
2009 4dr Sedan turbocharged 265hp 3.0L I6 Diesel
6-speed shiftable automatic RWD		 Always a glitch or two.
2009 4dr Sedan 414-horsepower 4.0L V8
6-speed manual RWD		 More prone to breakdowns than the Japanese competition.
2008 4dr Sedan turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD		 Does not require explanation.
2008 2dr Hardtop conv. turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD		 Possibly expensive repair track record when 4-year warranty end
2008 4dr Wagon 230-horsepower 3.0L I6
6-speed shiftable automatic RWD		 Poorer reputation than Lexus based on internet research. Stock run flat tires have short life and rough ride. Lack of spare limits options
2008 2dr Coupe turbocharged 300hp 3.0L I6
6-speed manual RWD		 not as reliable
2008 2dr Coupe 230-horsepower 3.0L I6
6-speed shiftable automatic AWD		 Historically, these cars have had their share of electronic gremlins.
2008 2dr Coupe 414-horsepower 4.0L V8
6-speed manual RWD		 I have never had major problems with my BMW's, but I have never kept them out of warranty either. M cars are ridiculously expensive to repair. The only car company where the coolant is designed to outlast the radiator. When they break, they brea
2008 4dr Wagon 230-horsepower 3.0L I6
6-speed shiftable automatic AWD		 Average is not good enough for a $40K+ car.
2007 4dr Sedan turbocharged 300hp 3.0L I6
6-speed manual RWD		 Had to take it to the shop twice already after the engine went into "limp home mode" on long business trips. Diagnoses from my dealer have been vague at best.
2007 2dr Coupe 230-horsepower 3.0L I6
6-speed manual RWD		 Have heard that some owners have problems with degradation of interior surfaces (chipping etc). I had an engine heat sensor fail within weeks of getting the car. Fixed easily enough, and no sequelae so far.
2007 4dr Sedan turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD		 Horror stories abound, fine while in warranty. Out of warranty SOL.
2007 4dr Sedan turbocharged 300hp 3.0L I6
6-speed manual RWD		 mirror glass blew up on its own, accessory belt ripped due to bad tensioner or steering pump pulley
2007 4dr Sedan turbocharged 300hp 3.0L I6
6-speed manual RWD		 The N54 engine is notorious for bad High Pressure Fuel Pumps, and BMW is known for having lots of annoying electrical niggles.
2007 2dr Coupe turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD		 High pressure fuel pumps are known to fail on these cars. Injectors and wastegates are also known to have problems.
2006 4dr Sedan 255-horsepower 3.0L I6
6-speed shiftable automatic AWD		 BMW has a bad reputation has being unreliable post warranty period. For the price we pay, the engine and drivetrain should be bulletproof for at least 150k miles.
2006 4dr Sedan 215-horsepower 3.0L I6
6-speed manual RWD		 Some interior rattles. Software and differential faults. Expensive service.
2006 4dr Sedan 215-horsepower 3.0L I6
6-speed shiftable automatic RWD		 Little electronic things tend to go wrong. Nothing serious with transmissions or engines but just annoying little things.
2006 4dr Sedan 215-horsepower 3.0L I6
6-speed shiftable automatic AWD		 awd problems
2006 4dr Sedan 255-horsepower 3.0L I6
6-speed manual RWD		 I fear that it will leave me stranded even though I love driving it and have had no trouble except one day the battery was completely dead when I was ready to leave work for no known reason.
2005 4dr Sedan 235-horsepower 3.0L I6
6-speed manual RWD		 Mechanically reliable, but various trim pieces and accessories could use some work. Window regulators fail and sunroof shades jam with disconcerting regularity. 2005 has been much better in this regard than 2000.
2004 2dr Coupe 225-horsepower 3.0L I6
6-speed automated manual RWD		 Pay more to maintain than a Toyota/Honda.
2004 4dr Sedan 235-horsepower 3.0L I6
6-speed manual RWD		 During the four years of ownership, the window regulators broke multiple times, causing the windows to "come off their tracks" and on one occasion fall into the door. Additionally, ignition coil failures at 20,000 miles were very disturbing.
2004 4dr Sedan 184-horsepower 2.5L I6
5-speed manual AWD		 what BMW considers wear items, that is, bushings, cooling system parts, should have a much longer life than they do, I bought this car used @4 years old, replaced to date: entire cooling system, rear bushings, rear springs, alternator, sunroof tracks,
