General Motors is pulling out 638,000 sport utility vehicles off the market in the United States due to faulty wheel-speed sensor.
According to the automaker, the sensor failure could activate the driveline protection system, potentially causing unintended braking of the wheel on the opposite side of the defective sensor. This could cause the vehicle to unexpectedly pull to one side, increasing the risk of a crash.
GM, however, clarified that it is not aware of any crashes or injuries relating to the issue, but shared that it found 150 claims from owners saying the problem caused unintended braking or lateral-vehicle motion.
One GM dealer also submitted a warranty report in May, where a 2018 GMC Yukon showed similar claims on the speed sensor. Two days later, a brand quality manager for GM submitted the report to the company’s Speak Up Safety program, which tracks potential safety issues, eventually prompting an internal investigation and testing.
The massive recall covers 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, as well as 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500, all equipped with a 5.3-liter engine, a 3.08-ratio rear axle, and a four-wheel drive setup.
Owners of the affected models are advised to expect recall notifications soon.
Chevrolet and GMC dealers will work on reprogramming the brake system software at no cost to consumers.
