My brakes went out at 4800 miles and it had no code but the dealership still fix it even though it didn't duplicate the problem it took a month to get it back and I am still terrified to drive it. I now have 5400 on my 2019 chevy high country which my family refuses to ride in.
My truck has been in the shop for about a month now and the part has come in says the dealer yesterday so I am waiting on them to put the master cylinder and brake booster on
