Traction control and abs. Acceleration jerking

- Knoxville, TN, USA

TL-the contact owns a 2008 Buick Enclave. The contact state that the vehicle experienced several failures the transmission gear could not be shifted out of first gear, the engine compression failed, the suspension sway bar failed, the traction control failed, and the rear lift gate opened on its own. The dealer replaced the transmission and all other parts that failed however the failures were not corrected. The manufacturer was not made aware of the failure. The failure mileage was 5,000 and the current mileage was 117,000.

I was driving and upon trying to press the brake the car jolted almost causing me to hit another car. The car said traction control off. I cautiously drove home with the same issue occurring but realize that the traction control kept going on and off constantly. When I read online about this issue I realized a lot of people with the same model and year are dealing with this issue no matter the mileage.

Twice within a month, while traveling at 70mph, my vehicle suddenly and quickly slowed to approx 20mph all on its own, with traction control and engine warning lights turning on. Vehicle would not accelerate and stayed at 20 mph. Ability to steer and brake was hampered, but on both occasions I was lucky enough to be able to ease over to the shoulder without being hit or hitting anyone else. Both times the car was taken to the dealer for repair, but because the dealer could not recreate the problem, the only remedy done was to clean the connections to the traction control module. It is sheer luck that no one was hit or injured.

Snowy conditions - about 2 inches on the ground; as I began to descend the hill near my home I tried to apply the brakes to keep a slow pace down the hill. Brakes failed and I began to slide down the hill. Steering was unresponsive; messages interchangeably flashed on the dashboard - 'service stabilitrak' and 'service traction control'. I had no control over the vehicle, and halfway down the hill jumped an 8" curb. Fortunate that the vehicle swerved to the right because there were parked cars to the left. Also, fortunate there were no people/children around, who could have been hit. $3000 damage to the underside of the vehicle. Very frightening to lose complete control of the car - I thought AWD, ABS, traction control and stabilitrak are supposed to help the driver maintain control of the vehicle in adverse conditions. Everything failed at once. Got the vehicle to the closest GM dealership; they ran diagnostics and surprise, everything checks out. They have no indication anything failed, so nothing further they can do except repair the physical damage. I experienced a complete failure of brakes, steering, traction, and electronic stability control and the dealership is telling me I did not - that the conditions were slick and that's what caused the accident. Isn't that when all of those safety features are supposed to engage? this is the first time I experienced a malfunction like this in this vehicle. Now I'm afraid to drive the vehicle, once it's fixed, esp. With other passengers. I may not even keep it.
