  SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM

  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.

  Remedy: 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.

  ELECTRONIC STABILITY CONTROL (ESC) · SERVICE BRAKES · SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:WHEEL SPEED SENSOR/TONE RING

  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.

  Remedy: 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.
