General Motors has issued a large recall for unintended braking happening to 638,000 U.S. market SUVs and trucks. This recall is due to a wheel-speed sensor which could fail.
The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive.
The concern is over the sensor failing leading to an unintended activation of the driveline protection system, and could cause unintended braking of the wheel on the opposite side of the failed sensor. This could lead to the vehicle pulling to one side unexpectedly, increasing the risk of a crash, GM said.
While there have been on accidents according to GM, there have been 150 field claims from customers about the issue.
According to Reuters.com, a GM dealer in May submitted a warranty report on the issue for a 2018 GMC Yukon. Two days later, a GM brand quality manager took that report and put it into GM’s Speak Up For Safety program to track potential safety issues. This prompted GM to investigate the problem further leading to this recall.
