Automatic Emergency Braking problems of the 2021 Chevrolet Silverado 1500

The brake stopped working. I just bought the car two months ago.

While driving, the emergency brake engages and locks the car up coming to a complete stop mid driving (on highway!). This has happened 3 times now, took it into dealer, they did a computer update and released. It has since happened again, with my child in the car!.

I was driving 60mph and went to accelerate a little bit more and my lifters went out and stated clicking.

While driving down a major, extremely dangerous highway [xxx] in pasco county, FL) my truck randomly shut off (with zero warning, no check engine lights, nothing) thankfully, I was already in the right hand lane and managed to coast into a gas station. At 60, 375 miles on my 2021 truck I was 352 miles outside of the powertrain warranty, so I had my truck towed to the closest chevy dealership to see if they would good-will the warranty. They (chevy) reported to me that there was a rod-knock with an estimate of $17,203. 52 to rebuild the motor. I would also have to pay approximately $2000 (10 hrs of labor) for tear down of motor to even see if gm would possibly pay out anything on warranty. I am the only owner of this truck since day 1. I have every oil change record that was done as specified by the manufacturer. I have no means of transportation at this time. My truck is available for inspection. I am also unable to take out any other vehicle loans while I am forced to pay for a truck that now, has no motor. Also, I went in for a recall of a software update for the forward collision system. Previous to the dealerships update, the system was working fine. After the update, the collision system no longer works. This is greatly affecting my ability to work, and function as a member of society. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When I am driving over 40mph and accelerate my breaks lock up. It's almost like I hit something really hard. It has done this at 70 mph and almost cause an accident behind me. My truck doesn't have automatic emergency braking on it. I have read a form a lot of people are having this same issue with this year and make.
