I had problems, after the first year, all the time and it was always in the shop. Thank goodness for everything free. At different dealerships, couldnt keep it running. it was a lemon, and no one would do anything about it! I got so mad on way to yet another appt,(over an hour, because of traffic, one way) I sold it (had bought it and not leased, didn't want to be stuck with it after expiring warrenty soon) and got a Z4, which I love and seems more reliable.
Redesign the trunk latches, which they did, windows had issues, drain on system (something electrical), extend the warrenty
