NHTSA Complaint #11634550 — 2021 CHEVROLET SUBURBAN

brake master cylinder failure, took car to chevy after brakes got super hard to push , luckily no accident , felt like no brakes, at the point of failure, brake light, abs light, check engine light all went on ,at some point abs and brake light went off but check engine light stayed on and screen on Dash indicated max speed 62 then in a couple of minute screen showed max speed 42 mph , then lights go off except check engine and vehicle works as it should it randomly does this in one day so vehicle was taken in to dealership where they had a hard time figuring out if thats the problem and contacted gm tech support gm and they said with these codes it should be the brake master cylinder, and it would cost me 3000.00 to fix. on an 80 000.00 car that's a 2021 with 82,000 miles and they are pretty certain that will fix the problem, I'm pretty sure I don't want to get in an accident at 65 to 70 mph and die I feel this is a huge safety issue and thank god wife and kids weren't in the car considering this is my wife's car to drive the kids around in
