Known issues on the 2022 Sierra 1500. Six recalls are on the federal record. A transmission control valve on diesel trucks can fail and lock the rear wheels, a mechanism that appears twice because a set of earlier repairs was carried out incorrectly. The 6.2L V8 has its own campaign covering connecting rod and crankshaft defects that lead to engine damage and failure. Chrome front grille deflectors could break their attachments and detach into traffic. Complaints total 571, with 165 on the engine, 99 on the power train and 90 on the structure.
