2010 Buick Enclave Vehicle speed control Problems

“Twice within the past month when driving on the interstate while using cruise control my vehicle automatically started accelerating uncontrollably. Depressing the brake pedal did not disengage the cruise control or stop the car from trying to accelerate. In both cases I had the wherewithal not to panic, control the vehicle to the shoulder, put the car in neutral and turn the engine off. After restarting the car the engine immediately continued to accelerate and throttle up to 4000 rpms while still in park. …”

“When driving the traction control light comes on then I get a signal that my engine power is reduced. The speed drops drastically on the highway. Indicators say system stabilization.”

“I was driving on the interstate going about 70mph. All of a sudden the light on my console said traction control off, service stabilitrack. My gas would not work, the power steering off and all the power was going. I barely made it to the shoulder. It was very scary also have my two children in the car. I looked up the problem in my book and it said to turn off and wait 15 seconds then turn on. That did not work. I sat there for about 30 minutes. I looked under the hood, underneath the car to see if anything was leaking. Nothing. Finally it would turn over and start. …”
