I was sold a used car w/ undisclosed accidents. Had many issues within first few weeks. Had transmission cooler lines replaced after they burst. Radiator, compressor, condenser, and much more. Then the Airbag light came on. Dealership said connectors were bad. Fixed it. Light came on again.took it in to dealership. They had it for over two weeks. The GM for all the dealerships Told me the vehicle was not unsafe and told me lies. But the service girl confessed she no longer had access to my vehicle or my file and her boss and the Gm had taken over working on it. She then told me they pulled Ford model air bags from my Chevy Impala. Now the light has come on again. I do not feel safe or rust the dealership to fix it properly.

While driving from work the car did a quick jerk and the STABILITRAK, ABS AND CHECK ENGINE LIGHT ALL CAME ON ALL AT ONCE. As I pulled into my workplace the car lost power to the engine completely while displaying ACTION REQUIRED ON THE LCD SCREEN. The brake and steering wheel became stiff and it was hard to control the vehicle. It took 10 minutes for me to regain power and control over the vehicle that again after leaving work stopped on the highway.

THE AC COMPRESSOR WAS REPLACED IN 2019 AND HAD BEEN SERVICED TWICE BEFORE THAT HAPPENED BECAUSE IT BLOWS EXTREMELY LOW AND HAVE TO PUT IT ON HIGH JUST FOR THE AIR TO BLOW. AS OF TODAY THE AC HAS BEEN GOING IN AND OUT EVEN AFTER THE REPLACEMENT OF THE COMPRESSOR AND STILL NO ONE CAN TELL ME WHAT'S THE ISSUE! *TR
