The breaks make a squealing noise all the time which is concerning. I was told by Beaver Chevrolet that this is normal as the breaks were changed in newer car models. They have made a squealing noise ever since I bought the car brand new.

NHTSA ODI report, 2026-08-23
fuel pump control module failed at 26000. recall number N252516900. This is a recall that other 2021 blazers have ben part of. Over 300000 recalls so far. GM says my car isn't. Ridiculous. They dont want to acknowledge their fault.
NHTSA ODI report, 2026-07-09
XXX the car had gas, turned over, but would not start. I had it towed to a repair center who towed, did diagnostics and came up with the codes for a bad fuel pump control module. It was replaced and the car starts. There was no warning.
