2005 Buick Terraza Owner Comments

problem #2

  • Automatic transmission
  • miles


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.

Terraza 6-cyl

  • Automatic transmission

The contact stated had a technician from GM look at his car because he was having many problems with his horn. E noticed problems with the horn on or around 5-20-05. It was very hard to push. The horn. You almost have to take a hammer to get it to blow. The dash lights are also very dim. He has found several complaints on the NHTSA website about the horn not blowing. Transmission kicks into passing gear too much going up slight grades on the interstate at 65-70 mph. The contact has driven other cars on the same interstas with the same average loads and with less horsepower and they didn't kick into the passing gear as much. The tech that GM sent out, said everything was normal.
