(stationary) i had problems recently with the stabilititrak, i stopped at the red light and the car started to shake too much and it went out, the light of stabiliti trak warning went on !! it has happened 3 times. (in motion) the other problem i had was the power steering, every time i turned the wheel of the car, it sounded like opening an old door. i had to go to the dealer and have it repaired. (in motion) another problem that i have is in the wheels, they have a sound like they have a pink can. but it is only heard sometimes not always. i went to the dealer to solve that problem but the sound left.
Engine power reduced, service stabilitrak light while getting off highway, car slowed down significantly. i cant imagine what may have happened had i still been on the highway. this is extremely concerning. apparently this is a know issue with chevy & gm cars. i have seen many forums and it seems nothing resolves this issue. there should be a recall on all chevrolet & gm cars.
