General Motors on June 27 announced four new recalls covering 428,211 vehicles in the U.S., the majority of which are full-size pickup trucks and SUVs that might inadvertently switch to neutral.

The truck and SUV recall includes 4-wheel-drive versions of the 2014-2015 model-year Chevrolet Silverado and GMC Sierra. Also included are the 2015-MY Chevrolet Tahoe and Suburban, along with the 2015-MY GMC Yukon and Yukon XL. In these vehicles, the transfer case may electronically switch to neutral without the driver’s input. If this occurs when the vehicle is in motion, no power will go to the wheels. If the vehicle is stopped or parked without the parking brake set, the vehicle might unexpectedly roll away.

Dealers will resolve the issue by recalibrating the transfer case control module software, GM said. This recall covers 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.

A second recall involves 4,794 2013-2014 model-year Chevrolet Caprice police cars and 2014-MY Chevrolet SS sport sedans in the U.S. These vehicles may have faulty windshield wiper modules. If the motor gear teeth become stripped, the wipers may not operate, GM said. Dealers will make an inspection and replace the windshield wiper module assembly if necessary.

A third recall involves 1,939 2014-MY Chevrolet Corvettes with FE1 or FE3 suspension in the U.S. Dealers will replace the two rear shock absorbers in these vehicles to repair a possible faulty weld. A weak weld could lead to a fracture or reduce the shocks’ service life.

Thirty-three additional vehicles were sold in Canada and another 82 were exported.

GM said it’s unaware of any crashes or injuries tied to any of the issues that prompted these three separate recalls.

A fourth recall -- one that the National Highway Traffic Safety Administration announced earlier in the day -- involves replacement of the driver-side air bag inflator in 29,019 2013-2014 model-year Chevrolet Cruze sedans in the U.S.

Additionally, GM is recalling 4,066 Cruze vehicles in Canada for the air bag inflator problem.

The inflators are at risk of rupturing and propelling metal fragments into the vehicle cabin. Such shrapnel-like debris could seriously injure the driver or passengers. Moreover, defective inflators would prevent the air bag from deploying properly in a crash.

GM said it is aware of one injury related to the issue.

Safety concerns over Takata-manufactured air bag inflators have led to new recalls by seven other automakers -- Mazda, Chrysler, Honda, Toyota, BMW, Ford and Nissan.
