More than 650,000 General Motors K2XX trucks and SUVs are subject to a safety recall as they may have a faulty wheel-speed sensor, in turn causing them to pull to one side when in four-wheel drive mode.
The defect: according to the official safety recall, a wheel-speed sensor on affected vehicles may fail, which can trigger the vehicle’s driveline protection system to activate when the vehicle is in 4WD mode. This can then provoke unintended braking on one side of the vehicle only, causing it to pull to one side when driving at speeds between 41 mph and 60 mph.
The hazards: unintended braking will happen on one side of the vehicle only, which will cause it to pull to one side, increasing the risk of a crash. Owners will know if a wheel-speed sensor has failed, as the vehicle’s electronic stability control (ESC) and anti-lock braking system (ABS) malfunction warning lamps will illuminate and the vehicle’s driver information center will display a “Service StabiliTrak” message.
Affected components: wheel-speed sensor, electronic transfer case, electronic brake control module.
Affected vehicles: the following models and model years are affected, but only when equipped with the 5.3-liter V8 engine, 3.08 axle ratio and 4WD. According to General Motors, 653,370 vehicles are affected by the recall worldwide, although no accidents or injuries have been reported so far.
- 2014-2018 Chevrolet Silverado
- 2014-2018 GMC Sierra
- 2015-2020 Chevrolet Suburban
- 2015-2020 Chevrolet Tahoe
- 2015-2020 GMC Yukon
The fix: dealers will reprogram the electronic brake control module (EBCM) in affected vehicles. GM says this is a “phased launch” as the revised software is already available for 2019-2020 Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon, but GM is still working on software for the 2014-2018 model-year Chevrolet Silverado and GMC Sierra 1500, and 2015-2018 model-year Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon. This repair will be made at no cost to the customer.
Owners should: customers who own an affected vehicle will be notified by mail by General Motors and instructed to make an appointment with their dealer. If owners are unsure whether or not their vehicle is affected, they can visit my.gm.com/
