While traveling down the road at approximatly 35-40 mph with my two minor children, the steering was not responding properly and the car kept attempting to veer to the right. I let off the gas to slow down since the brakes were also not seeming to respond well. Upon attempting to brake and execute a left hand turn, the car would not turn at all despite the steering wheel being as turned as far to the left as possible, the lights began flashing on the dashboard for "PowerSteering" ESC warning. We ended up going through the intersection without stopping and narrowly missed another car in intersection and went completely off the road into a snowbank. Fortunately we were not injured. We drove the vehicle back home (approximately one mile) by overpowering the steering and manually forcing the car to stay on the road. Throughout the lane assist kept attempting to autocorrect and drive us off the road. The car was damaged by the impact and the mechanic said that the tie rod is bent and has no idea what could have caused this to happen. I am somehow now responsible for the situation. I have asked what caused the power steering to fail, and Chevy claims that they have no record of any power steering issues (which research has shown to be untrue) and in order to determine IF it failed and/or why, they need to make the repair and then run additional tests to re-create the issue. This car only has 21,000 miles on it, and has never been in an accident before this.

Purchased my 2021 Chevy Trailblazer in August 2021 with less than 100 miles. After about 500 miles the Lane assist, forward collision assistant and the automatic breaking features all stopped working. Factory reset has been set several times with no fix. The buttons on the steering wheel do not do anything when pressed. I have been told by the dealership they will need to keep my car for at least 3 days to disassemble and trouble shoot the issue, however they do not have a rental to provide me in the mean time. I am now at around 10K miles because this is my daily driving and only vehicle. I am not comfortable that some of the safety features have stopped working and fear that any day something else could stop working that is more important to the functioning of the car.
