GM recalls 7,800 Cadillacs, Acadias, Blazers and Traverses

The transmission may have been built with an incorrect sun gear, which can result in the driver-side half-shaft disengaging from the transmission.

Disengagement of the half-shaft 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.

Dealers will replace the sun gears free of charge.

Owner notification letters are expected to be mailed May 1, 2023.

Owners may contact Cadillac customer service at (800) 458-8006, Chevrolet customer service at (800) 222-1020, or GMC customer service at (800) 462-8782. GM's number for this recall is N222389310.
