General Motors, LLC (GM) is recalling certain 2023 Cadillac XT6, GMC Acadia, Chevrolet Blazer, Traverse, and 2022-2023 Cadillac XT5 vehicles. The transmission may have been built with an incorrect sun gear, which can result in the driver-side half-shaft disengaging from the transmission.
Risk if Unfixed
A half-shaft disengaging from the transmission can result in a loss of drive power or vehicle rollaway when the vehicle is placed in park. Either of these scenarios can increase the risk of a crash.
Free Fix
Dealers will replace the sun gears, free of charge. Owner notification letters were mailed on July 27, 2023. The remedy is expected to become available August 31, 2023. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GMC's number for this recall is N222389310.
Your vehicle's left-side driveshaft assembly may be missing a critical retaining ring that keeps it securely in place.
Risk if Unfixed
If this ring is missing, the driveshaft could come apart, causing your vehicle to lose power or roll away when you put it in park, which could lead to a crash.
Free Fix
You should take your vehicle to a dealership, where they will replace the left-side half-shaft assembly for free. They've already sent you a letter about this, but you can also contact Chevrolet at 1-800-222-1020 for more information and to schedule an appointment.
