2010 4dr Wagon turbocharged 211hp 2.0L I4
6-speed shiftable automatic AWD
65,000 miles and not a single problem other than routine oil changes and tires. My BMW 335i is always in the shop and is a maintenance nightmare.
2006 4dr Sedan turbocharged 200hp 2.0L I4
6-speed manual AWD
This car is bullet-proof. End of story. The B7 A4 is the evolution of B6/B7 platform and most of the kinks are ironed out in the final years. No worries here.
2006 4dr Sedan 255-horsepower 3.1L V6

So far, perfect
2006 4dr Sedan turbocharged 200hp 2.0L I4

so far so good, but I have only had the car less than a month, too soon to tell

2010 4dr Sedan turbocharged 211hp 2.0L I4

Very expensive to fix and not with the same history of reliability as Benz.
2007 4dr Sedan turbocharged 200hp 2.0L I4
6-speed shiftable automatic AWD
My second A4 is better than the last, but I am glad I leased instead of buying. Reliability is just not world class.
2006 4dr Sedan turbocharged 200hp 2.0L I4
6-speed shiftable automatic AWD
Not reliable, lots of dealer visits,
2006 4dr Sedan 340-horsepower 4.2L V8
6-speed manual AWD
Do not buy one of these used unless the timing chain pre-tensioners have been replaced. There are a lot of complaints of these breaking at 100,000 miles. Mine went at 99,100 miles and the dealer quoted me $10,000 to fix. I had to sell this car at a loss. What a waste!
2005 4dr Sedan turbocharged 170hp 1.8L I4
5-speed shiftable automatic AWD
In the shop 10 times during last seven months. Towed 4 times because not drivable
2005 4dr Sedan 340-horsepower 4.2L V8
6-speed manual AWD
The two cars I looked at were low mileage 2005s, CPO, and both had full service history, of which there was a lot. Both cars noted cooling issues and problems with the steering system repaired under warranty. Also numerous electrical problems.
2004 4dr Sedan turbocharged 170hp 1.8L I4
5-speed shiftable automatic AWD
Reputation for mechanical problems and expensive repairs
2003 4dr Wagon turbocharged 170hp 1.8L I4
5-speed manual AWD
The car is not reliable - sensors, electrics, etc.
2002 4dr Sedan 220-horsepower 3.0L V6
6-speed manual AWD
Had to have many repairs before all the bugs worked out - now seems reliable (knock on wood)
2002 4dr Sedan turbocharged 250hp 2.7L V6
6-speed manual AWD
The high tech nature of these cars requires somewhat more attention to maintenance.

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 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.

Glovebox won't open.
2010 4dr Sedan 230-horsepower 3.0L I6

Small things keep breaking or failing. The engine and drivetrain are solid though.
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 4dr Sedan 414-horsepower 4.0L V8
6-speed manual RWD
More prone to breakdowns than the Japanese competition.
2009 4dr Sedan turbocharged 265hp 3.0L I6 Diesel
6-speed shiftable automatic RWD
Always a glitch or two.
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.
2008 4dr Sedan turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD
Does not require explanation.
2008 4dr Wagon 230-horsepower 3.0L I6
6-speed shiftable automatic AWD
Average is not good enough for a $40K+ car.
2008 2dr Coupe 230-horsepower 3.0L I6

Historically, these cars have had their share of electronic gremlins.
2008 2dr Coupe turbocharged 300hp 3.0L I6
