General Motors is recalling certain trucks and SUVs over a very serious problem: possible unintended braking.

The issue is caused by a faulty wheel-speed sensor that could fail, leading to the braking of the wheel on the opposite side. Should this happen, the vehicle will pull to one side unexpectedly, increasing the risk of an accident. The automaker is, so far, unaware of any crashes and/or injuries related to this condition.

Included in this safety campaign are 638,068 units of the 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2015-2020 Chevrolet Suburban, Tahoe and Yukon. All of them feature the 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive, and GM estimates that only 1 percent has this defect.

An owner notification schedule has yet to be provided, but GM has started informing dealers about the recall since October 24. The fix will see technicians reprogram the Electronic-Brake Control Module (EBCM) software, and all work will be carried out free of charge. Those who have already repaired their trucks/SUVs will be reimbursed according to the plan submitted on May 17, 2019.

Owners who want to find out more about the safety campaign can get in touch with Chevy at 1-800-630-2438, GMC at 1-800-462-8782 or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236. In the meantime, GM recommends operating the vehicles in two-wheel drive to eliminate the risk of unintended braking.
