2009 BMW 5 Series 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
The car was awesome at first but then came the problems the fuel system replaced 3 times. The car continues to have fuel delivery problems. BMW told me we have extended the warranty to 10 years on the fuel system but that doesn't help when you're stranded on the road. Avoid the 135/335/535 models they are garbage. I have started the lemon law process.
I had the same problem and gave similar ratings.
I just noticed that Edmunds averages all the rating categories, so your lemon shows up as a 4.5 star car!
Guess I need to change some of the categories to make an impact :-)
