BMW 3-Series vs. BMW Z3 Reliability Comparisons

You won't find BMW 3-Series or BMW Z3 reliability information like this anywhere else. Actual repair frequencies, not just vague dots, to make it clear how much the BMW 3-Series and the BMW Z3 truly differ in reliability.

These stats are promptly updated four times a year, to much more closely track BMW 3-Series and BMW Z3 reliability as the cars age. Others tell you how reliable the BMW 3-Series and the BMW Z3 were a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the BMW 3-Series and the BMW Z3 have been recently.

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.
2009 0 My car has been very reliable. I got a cerfited pre owned so all things a free at dealer. If you are buying one, then get a cpo one. well worth it.

2008 4dr Sedan turbocharged 240hp 2.0L I4
6-speed manual RWD
The car has a BETTER THAN AVERAGE frequency of repair record with Consumer Reports.
2008 2dr Coupe turbocharged 425hp 3.0L I6
7-speed automated manual RWD
Not yet tested to a full extent on my M3 under review, bust as previous BMW owner I enjoyed minimal component failures after many years of ownership.
2008 2dr Coupe turbocharged 300hp 3.0L I6
6-speed manual RWD
History is promising.
2008 2dr Coupe turbocharged 300hp 3.0L I6
8-speed shiftable automatic RWD
Historically, reliable
2008 2dr Hardtop conv. turbocharged 240hp 2.0L I4
8-speed shiftable automatic AWD
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.

Glovebox won't open.
2010 4dr Sedan turbocharged 300hp 3.0L I6
6-speed manual RWD
Small things keep breaking or failing. The engine and drivetrain are solid though.
2010 4dr Sedan turbocharged 300hp 3.0L I6
6-speed manual RWD
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 4dr Sedan turbocharged 425hp 3.0L I6
6-speed manual RWD
More prone to breakdowns than the Japanese competition.
2009 4dr Sedan turbocharged 255hp 3.0L I6 Diesel
8-speed shiftable automatic RWD
Always a glitch or two.
2009 2dr Coupe turbocharged 240hp 2.0L I4
8-speed shiftable automatic AWD
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.
2008 4dr Wagon turbocharged 300hp 3.0L I6
6-speed manual RWD
Average is not good enough for a $40K+ car.
2008 2dr Coupe turbocharged 300hp 3.0L I6
6-speed manual RWD
Historically, these cars have had their share of electronic gremlins.
2008 2dr Coupe turbocharged 300hp 3.0L I6
6-speed manual RWD
not as reliable
2008 4dr Wagon turbocharged 240hp 2.0L I4
8-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

I experienced continued problems with the A/C system and the engine cooling system. Also, the rag top did not hold up well and developed a leak.
