While driving at night from a field trip with my daughter and her girl scout brownie troop, the stability track system went on in error and I lost control of the car. It went from 40 mph to 5 mph within a second. The steering would not work, either. Very, very scary! I contacted onstar in the car and they could not see a problem, but sent a tow truck. The dealership replaced a short-wire and said it was fixed. But could it happen again? also, my automatic doors never work properly. We bought this car for family trips and field trips, but now I'm too scared to take it on trips or field trips thinking that it will happen again on the express way like it did to other terazza owners. We leased it so I can't get rid of it. Instead I make a huge payment every month on a lemon.
