GM trucks and SUVs may suddenly pull to one side

NHTSA campaign 19V761000 · Reported 2019-10-24 · General Motors LLC

high How serious is it? About this label

Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash. The notice does not tell owners to stop driving.

What's wrong, in plain English

On these 5.3-liter four-wheel-drive trucks and SUVs, a failed wheel speed sensor can fool the brake computer into braking one wheel by itself. It happens between about 41 and 60 mph in four-wheel or automatic mode, and it makes the vehicle pull toward one side with no warning to the driver. The repair is a free software update to the brake control computer at the dealer. Owners were notified starting in December 2019.
