“The transmission may have been built with an incorrect sun gear, which can result in the driver-side half-shaft disengaging from the transmission,” the report said. “This condition can cause the driver-side half-shaft to disengage from the transmission, causing a loss of propulsion and/or a loss of mechanical park.”

The recall affects different makes and models manufactured by GM.

According to the report, the loss of propulsion or mechanical park can increase the risk of a crash and a roll-away. If the vehicle has the problem, drivers might hear a clicking or grinding noise from the front of the vehicle.

Recalled vehicles:

· 2023 Cadillac XT6 (613 vehicles)

· 2023 GMC Acadia (1,059 vehicles)

· 2022-2023 Cadillac XT5 (783 vehicles)

· 2023 Chevrolet Blazer (444 vehicles)

· 2023 Chevrolet Traverse (4,941 vehicles)

GM said it had received 164 complaints potentially related to the issue, but none that resulted in crash or injury.

Owners will receive a letter about the fix by May 1. The repair is free.
