Service Brakes, Hydraulic:power Assist:vacuum 2020-10-01 · campaign 20V603000 · 14,620 vehicles
Defect: General Motors LLC (GM) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5.3L or 6.2L V8 engine. The output of the mechanical vacuum pump can decrease over time, decreasing the amount of vacuum/power brake assist.
Risk: A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.
Fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began November 11, 2020. Owners may contact GM customer service at 1-866-522-9559, Cadillac customer service at 1-800-458-8006 or Chevrolet customer service at 1-800-630-2438. GM's number for this recall is N202300860.
Service Brakes 2019-10-24 · campaign 19V761000 · 652,967 vehicles
Defect: General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC 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. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Risk: 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.
Fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.
Service Brakes, Hydraulic:power Assist:vacuum 2019-09-06 · campaign 19V645000 · 3,456,719 vehicles
Defect: General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.
Risk: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
Fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.
