After two hub failures, stabilizer link failures, ignition coil failure, rear defroster failure, power locks failure, and now the steering rack is making a grinding noise and causing premature wear to the front right tire. I believe there is a TSB on the steering rack. This should be a recall I won't ever by a gm again.
