My car is trying to kill me. At a complete stop when I hit the gas the traction control comes on. My dash says service stabilitrak, traction control and ABS. I must turn off the traction control to drive my vehicle. With all that, if I drive up hill it turns the traction control on, the ABS and traction control light up and the lights stay on. When the car is restarted all the lights go away. Twice I was pulling onto the highway from a stop. That situation happened and my car didnt move. Luckily the car was able to move or else I would have severly injured. This happens with my vehicle daily. I took my car in because my alternator failed. I told the dealership about a tsb for the issue and they did nothing. It also happens a lot if im accelerating while turning a corner. The dash lights up like christmas lights.

Driving 55 mph on the interstate noticed that I hadn't filled up in a while yet the fuel gauge still read "completely full". filled up at gas station took 3/4 of a tank. Gauge has been alternating between full and completely empty for a month. Could have run out of gas at speed on interstate causing accident internet research has uncovered a few incidents like that. Chevy support is willing to waive the 50 dollar diagnostic fee but will not cover repairs. Local garage quoted 250 labor 160 part to replace fuel gauge sensor in the tank, but from online research past years have seen instrument cluster failures in fuel gauge, speedometer and engine temp. Car has 50800 miles on it is four years old and may require repairs 400-2K depending on which part is failure. Previous GM products have had class action lawsuits for similar issues. This is a safety issue as the gauge fails and the check engine light took 25 days to come on with the error code in the 460's that the sensor was bad. Currently driving vehicle with broken fuel gauge and submitting complaints talking with support to try to get them to cover repairs.

When I start driving on local street each morning, I make a left turn, the car makes a loud grinding noise and my service traction control, service brake assist, & ABS light all come on. They also go on & off when I go over speed bumps make a loud grinding noise. The traction control symbol will come on and I will be stuck trying to accelerate. This is very dangerous as I have almost been hit from behind a few times due to not being able to accelerate in a timely fashion. I have gone on Chevy Impala forums looking for other drivers who may have experienced this are there are a good number of them. It seems to be an electrical problem. I finally took it to a mechanic and they could not reproduce the problem. It still happens.
