General Motors is recalling 638,068 model year 2015-2020 Chevrolet Suburbans, Tahoes, & Yukons, and model year 2014-2018 Chevrolet Silverado 1500s and GMC Sierra 1500s vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive.
If a wheel-speed sensor fails, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
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.
What to do
GM will notify owners, and dealers will reprogram the EBCM free of charge.
The manufacturer has not yet provided a notification schedule.
Owners may contact Chevrolet customer service at (800) 630-2438 or GMC customer service at (800) 462-8782. GM's number for this recall is N192261050.
