General Motors has decided that a problem affecting vehicle steering exists in certain 2021 Cadillac, Chevrolet and GMC trucks. GM opened an investigation into the condition after receiving a field report of loss of power steering assist in a 2021 GMC Yukon.
According to the defect report, diagnostic trouble code (DTC) data obtained from the vehicle indicated that the power steering system may contain a software error that causes loss of power steering assist at startup or while driving. Vehicle testing demonstrated that manual steering remained available without power assist, but increased steering effort was required, particularly at lower speeds. In most cases, the malfunction indicator light will display on the instrument panel and a warning chime will sound. The condition is typically self-corrected at the next ignition cycle.
