GM does not care about their customers. I've seen several reduce engine speed ,even wrecks bc car just stops.

Impala LT V6

  • Automatic transmission
  • 91,000 miles

While coming from work driving on a busy road, the car lost power and all the lights cut off. I had to slowly pull the car over the steering wheel barely wanted to turn. I was very scared. After pulling the car over I tried to start it and it started right away. All these issues with this car have left me so confused. There's no check engine light on every time I take it to someone they charge me to diagnose it and have no answers.

Impala LT 3.5L

  • Automatic transmission
  • 35,000 miles

I had the same problems as everyone else, service Stabilitrack, engine power down which it died in the middle of the freeway on my wife and she almost got hit by a semi. Sputtering when going around corners and on take off. I had the torque converter and Tcc solenoid replaced, gas pedal and it still continued to sputter. So I took it to a independent shop and after testing they found a loose wire which they fixed and the car wouldn't start so they wiggled the harness and it did start which led them to believe the engine wiring harness is faulty which is a GM defective part. They said it makes sense for it to set off the Stabilitrack since the car is ran off that harness.
