I bought my BMW X5 3.0 brand new. I've had nothing but problems.
The most recent issue happened without any warning. The drivetrain and both front and rear transfer cases gave out. The cost to repair is $5200 USD.
I called BMW, and they admit they designed the drivetrain too short, which will cause unnecessary wear on the transfer case(s), which in turn was the cause of the transfer cases giving out too. The replacement drivetrain is a "modified" drivetrain that is longer. In my opinion, this constitutes a defective or faulty drivetrain! This means the drivetrain and/or transfer cases will give out, it's just a matter of time. BMW will not own up to the fact and stand behind their product.
I understand that I have 137k miles on my BMW, but I'm appalled that BMW knows about this and doesn't issue a recall, or at least notify its customers.
I will NEVER own another BMW!
Would you buy another car from this manufacturer? No
