general problems of the 2009 Chevrolet Tahoe Hybrid

Gm has not been able to figure out my car. It has been in three times for an eltrical issue. The car revs up and speeds up to 55 miles per hour on its own. Has no power steering. Reduced engine power. Throwing 47 codes. No communication between transmission and computer. Stability track turns off. Doors and auto shut off turn off and on when this occurs.

When I press down on the gas, my vehicle stalls about five seconds before it actually takes off. When I try to stop, it does not stop right away as I press down on the break. I've almost rear another vehicle on several occasions while sitting at a red light. I have to stay at least 15 feet away from the vehicle in front of me. My vehicle has shut down while I was driving. My engine light comes on and goes off periodically. If I turn my wheel to sharply (reverse or forward), it jerks, makes a loud noise, and then it feels like its about to cut off. I feel really unsafe driving, however, I have no choice because I have to work.

The contact owns a 2009 Chevrolet Tahoe Hybrid. The contact stated that the service engine warning light and various warning indicators randomly flashed at a high rate of speed. The instrument cluster randomly shorted out while driving approximately 75 mph. Also, there was a drastic reduction in speed and the vehicle stalled. The contact had to apply extreme force to the steering wheel and the power steering assist failed. The contact was able to coast the vehicle over to the side of the road. The vehicle was towed to the contact's residence due to the sudden failure. An independent repair shop inspected the vehicle and was able to review the diagnostic trouble codes, but was unable to provide a diagnosis to repair the vehicle. The vehicle was to be inspected and diagnosed by a dealer to determine the failure. The manufacturer was notified of the failure. The approximate failure mileage was 110,000.

The contact owns a 2009 Chevrolet Tahoe Hybrid. After driving the vehicle and aproaching a stop, the vehicle was supposed to shift from gas to electric. However, it involuntarily accelerated even with the brake pedal depressed. In order to stop the vehicle, it had to be shifted to neutral. The contact drove the vehicle to the dealer, but they could not duplicate the failure. The failure occurred multiple times. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 135,000.

The electric door locks that engage when the vehicle is placed in gear have stopped working. If a parent relies on this system the doors may not lock resulting in a dangerous situation. This is a system failure. . .

I have never had any issues other than the recalls with my tahoe. I pulled into a parking space at my bank. As I got into the space. The brakes went to the floor and I put both feet on the brake pedal at this point. The rpms went up. It was like the engine came to life by itself. It self accelerated over the concrete spacer and sidwalk into the bank's brick wall. The airbag deployed upon impact. There was never a time it decelerated. There was no one in the car but me thankfully. There were no warning lights. There were no bells warning of the failure. I would estimate it took 2-3 seconds to go from almost stopped in a parking space to hitting the brick. I am so shaken by this incident and I have no idea what to do. GMC has been informed.
