Dealers will recalibrate transfer case control module software in 392,459 full-size pickup trucks and SUVs in the U.S. and 53,607 in Canada. An additional 20,874 were sold outside the U.S. and Canada. Affected are four-wheel-drive versions of the 2014-2015 Chevrolet Silverado and GMC Sierra; the 2015 Chevrolet Tahoe and Suburban; and the 2015 GMC Yukon and Yukon XL.
In these vehicles, the transfer case may electronically switch to neutral without input from the driver. If this occurs while a vehicle is in motion, no power will go to the wheels. If the vehicle is stopped or parked, it may roll away if the parking brake is not set. GM is not aware of any crashes or injuries related to this issue.
Dealers will inspect, and replace if necessary, the windshield wiper module assembly in 4,794 2013-2014 model year Chevrolet Caprice police cars and 2014 Chevrolet SS sport sedans in the U.S. If the motor gear teeth become stripped, the wipers may not operate. GM is not aware of any crashes or injuries related to this issue.
Dealers will replace the two rear shock absorbers in 1,939 2014 model year Chevrolet Corvettes in the U.S. with the FE1 or FE3 suspension to repair a possible insufficient weld in the rear shocks that could lead to a fracture and/or reduce the shocks' service life. Thirty-three additional vehicles were sold in Canada and another 82 were exported. GM is not aware of any crashes or injuries related to this issue.
