My headliner has fallen down 3 times Plastic rocker molding fell off Engine knocking, car blowing blue/gray smoke, only getting 15-17MPG with regular fuel The car has been in the shop now for 2 weeks, with no real answers to the issues of poor MPG and the engine knocking. I was told it is "normal" for a new car to have blue/gray smoke coming from it until it is broke in. I have a meeting with GM's regional manager next week. RUN FROM THIS CAR! GM has not changed for the car company of the 1980s, they are still making junk (I will give them it looks better, dives better, and may use better materials) but the reliability and quality is still the same.
