 I bought this car new and since the day I drove it off the lot it's knocked in the front left suspension and no one will attempt to repair it.  They tell me they "can't just throw parts in the car" without replicating the sound.  Well a technician heard the noises and said it's not the tires.  Two dealerships recommended I change the tires to All-Season tires which I do not want on my high performance car.  So they think I should be the one to "just throw parts on the car" to see if it fixed the problem?  Are you kidding me?!  Look, if they just made a reasonable attempt to resolve it, I'd be OK.  But it's sad that I spent $170,000 on this thing with prepaid service and taxes, and they won't even attempt to solve it by changing out a shock absorber, bushing, or strut; even when the tech heard the noise and said "yep, it's not the tires".  HATE IT!  Probably going back to BMW.  I have to be honest, if I wasn't having this issue for over a year now, the rating may be a 4 or maybe even a 5.
