6-speed shiftable automatic AWD
Full service for first 4 years.

Tried and true inline 6 cylinder engine.
2002 4dr Sedan 184-horsepower 2.5L I6
5-speed shiftable automatic RWD
Very little rust after 8+ years coupled with top notch materials lasting quite a long time. Replacement parts were very costly but performed for long periods. Current owners offer great advice on what and when to perform preventative maintenance.
BMW 5-Series Reliability and Durability: Cons
YearBody/PowertrainComment
2011 4dr Sedan turbocharged 300hp 3.0L I6
8-speed shiftable automatic RWD
- accelerator response (hesitation) - engine issues (check engine light requiring three service visits in two months) - engine malfunction light (part of turbo came disconnected) - faulty fuel sensor (recall first three months of new model year)
2010 4dr Sedan turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD
Unbelievable maintenance after 50K miles, cost and effort.
2010 4dr Sedan turbocharged 300hp 3.0L I6
6-speed shiftable automatic RWD
Terrible reputation for poor reliability and absurdly high repair costs as early as 50,000 miles.
2005 4dr Sedan 325-horsepower 4.4L V8
6-speed shiftable automatic RWD
Over 80K many systems were beginning to break down
2004 4dr Sedan 225-horsepower 3.0L I6
6-speed manual RWD
Had several repairs the first month of ownership that were covered by CPO warranty...love that BMW CPO
2002 4dr Sedan 290-horsepower 4.4L V8
5-speed shiftable automatic RWD
I picked the above "reason" because it's the worst feature of an otherwise perfect vehicle. The durability of the interior is quite frankly an embarassment. I've lost the buttons for max for the heater, up for the driver side temerature, and the top button for the airflow direction .... don't ask me where they went, they just disappeared! I've broken the drivers side cup holder (and come on ... how pathetic are those cup holders!), and once it breaks, it no longer clicks back into the closed position so now I have a half a cup holder sticking out. One other grievance relating to interior durability ... the plastic footrest (left foot) down below the hood lever also fell apart. The plastic just broke away in
2002 4dr Sedan 225-horsepower 3.0L I6
5-speed shiftable automatic RWD
This car is known to have a plethora of problems. I have yet to see if it will hold up well for me.
2001 4dr Sedan 225-horsepower 3.0L I6
5-speed shiftable automatic RWD
dealer ship as a mess

My third Lexus- all impressive products requiring little or no dealer visits or upkeep
2008 4dr Sedan 292-horsepower 3.5L V6 Hybrid
6-speed shiftable CVT RWD
I have had absolutely no problems with this car. Just take it in for oil every 5000 miles and all is well!
2008 4dr Sedan 303-horsepower 3.5L V6
6-speed shiftable automatic AWD
Think it continues to have the best record for reliability and durability for any brand at the same price point
2007 4dr Sedan 292-horsepower 3.5L V6 Hybrid
6-speed shiftable CVT RWD
No faults so far Good word of mouth on reliability Above average warranty offering, which allays fears of reliability problems

6-speed shiftable automatic RWD
never fails to run superbly
2002 4dr Sedan 220-horsepower 3.0L I6

Lexus GS Reliability and Durability: Cons

2006 4dr Sedan 245-horsepower 3.0L V6
6-speed shiftable automatic AWD
I am very disappointed inte reliability of this Lexus. I've always believed the hype about the excellent reliabiity of the Lexus brand. I have not had any major problems, but it seems there is always something coming up. It is the only car that has stranded me or my wife in the pst 10 years, and that wtih a pinhole in the radiator. The radiator is very cheaply made, easily damaged by road debris. This car has been to the shop more than any car I've owned in the last 10 years other than my 1980 Porsche 911 and it sate 10 years before I bought it. The list of issues includes no catastrophic problems but I am more than likly to get rid 0f it before something major does happen. Not sure if i bought a lemon of if the 2006, being a major upgrade year model is experiencing the pain of new model syndrome.
