NHTSA Complaint #11440011 — 2012 CHEVROLET TRAVERSE

UNKNOWN, I first bought my Chevy Traverse Ltz in April of 2020, and about 2 weeks of driving it, I noticed that all(4)of my wheels/brakes instantly locked up while driving in traffic, almost causing a pile-up collision. The rotors and brakes releases alot of smoke as the wheels scrub and the suv doesn't move forward nor backward. I reported it to the car lot/dealership where i purchased it from and was told to take it to a certain auto shop. I arrived there, just to be told that he doesn't fix those type of problems. The dealership where i bought it from didn't look at it either. So, from that time til now in 2021, I have been dealing with the same exact problems being terrified with my children in the car, not knowing if/when the next time the wheels lock up for no reason, if it will be fatal for me and my children or other drivers. I've contacted GM about it, taken it to Chevy dealership a few times, even a couple of auto shops, and no one seems to know what the problem is. I recently had the transmission serviced to see if that was the issue and turns out, it wasn't. I don't know what to do, I am still financing it and the warranty only covers the transmission and engine, half the cost of the repair and the other half is my responsibility it states. I've been trying to prevent any fatal accidents best I can, sometimes by not driving it at all and having to ride with family members and friends. I was recently told by my warranty company that there is pretty much nothing they can do about it.
