While driving home, the vehicle started to smoke. The windows were rolled down, the air conditioner was off and it is about 86 degrees outside. This isn't the first quirky incident to happen in this vehicle. I just bought it about 7 months ago. All the standard maintenance has been done to this vehicle. Not sure why it is smoking. After it being in our care for 4 months, the check engine light will also not go off, and the remote start doesn't work anymore. The driver side door has become loose as well. No one has been hanging on it, just simply opening and closing the door. Also the plastic cap on the shift has popped off. I will be getting it checked tomorrow and possibly getting rid of it sooner than later. This is a very poor gm model car.
