NHTSA Complaint #11551208 — 2018 CHEVROLET MALIBU

My turbo failed while I was on a very busy highway, causing me from going 70mph to 35mph in a matter of seconds and almost being hit. This put my life and my friends life at risk since we were in the left lane. Now that I’ve been fighting with the dealership ti help make this right they found a GM warranty that fixed and updated electrical sensors. We fixed that first because at the time we thought that was what it was. My turbo gave out again up in the mountains almost killing me and my friend a second time on a busy road. We made it to a parking lot and called a tow truck. Now the stabiltrak is showing up and the car refuses to start, it makes a whooshing sound and doesn’t start completely. (There is fuel, oil, etc). I was sold an unsafe vehicle and now I’m stuck paying 500$ a month for a car that’s unsafe and refuses to work even when it’s been fixed. The dealership is refusing to help me, I’m at a loss. I still owe 18k and I can’t have an in working car sitting in my apartment complex, it will get towed and cost me more money.. I need help. I was sold a car that almost killed me twice and no one seems to care.
