2003 Audi A4 3.0 quattro AWD 4dr Sedan (3.0L 6cyl 6M)
As I drove off the lot, the Xenon headlight leveling sensor warning light went on. I had to leave it overnight the first night I owned it! This was a problem that had to be fixed three times in the first year I owned it. My remote trunk release works only sporadically and I've had to fix it three times so far...this number would be higher if I hadn't given up on fixing this problem. I've had problems with the power window switches, power mirrors, and the memory power seats. At 3 years, the rubberized trim around the cabin began to flake off. Though no major engine disasters (so far), I've had many other problems requiring time in the shop!
Handles well and is relatively fun to drive when it isn't in the shop. But it is still no BMW.
Reliability!! All would be forgiven if I didn't have to drive a loaner/rental all the time.
