In June 2014, General Motors recalled more than 400,000 pickup trucks and SUVs because of an issue that could electronically switch the transfer case to neutral without driver input. The vehicles affected included four-wheel drive models of the 2014-2015 Chevrolet Silverado, GMC Sierra models from the same year, and the 2015 models of the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon and Yukon XL.
General Motors, in what was a record-breaking year for recalls, announced a safety recall for over 400,000 pickup trucks and SUVs for transfer case problems in 2014. GM pointed out an issue with the transfer case control module software that could switch the transfer case to neutral by itself. If this happened when the car was in motion, it would lose power to the wheels. If it occurred when parked, the car could roll away, depending on whether the parking brake was set or not. The solution to the problem was to recalibrate the software, a process that dealers were tasked with. The issue affected vehicles sold mostly in the U.S. and Canada, and included the company's most popular model — the GMC Sierra pickup truck.
In 2014, GM made 48 recalls, totaling over 20 million cars, as stated by Tech Times. The previous record year for the company was 2004, with 10.74 million cars recalled.
