General Motors Friday announced three more safety recalls covering nearly 475,000 vehicles, the biggest of which involves a software problem in some leading sport utility vehicles and pickup models.
GM will recall more than 450,000 models of the 2014-2015 Chevrolet Silverado and GMC Sierra, among others, in which control module software in the four-wheel drive system could automatically switch to neutral without driver input.
As a result, a vehicle, while parked, could “roll away if the parking brake is not set,” GM said. If the vehicle is in motion, no power will go to the wheels, the automaker added.
GM said it knew of no crashes or injuries related to this problem, or to those that prompted the other two recalls it announced. The recall affects vehicles in the US and Canada.
GM said it was recalling about 4,800 2013-2014 Chevrolet Caprice police cars and 2014 Chevrolet SS sport sedans in the US to address a problem that can stop the windshield wipers from working.
The third recall involves about 2,050 2014 Chevrolet Corvettes, most in the US, to address a problem with the rear shock.
GM has already recalled more than 20 million vehicles in 2014.
The Detroit automaker is under investigations by Congress, the Justice Department and the Securities and Exchange Commission over its delayed recall of cars with ignition switch problems related to at least 13 deaths.
In February — 11 years after the ignition switch defect was detected — GM began recalling 2.6 million Chevrolet Cobalts, Saturn Ions and Skys, Pontiac 5s and Solstices made between 2003 and 2011.
