Power train · transfer case (4-wheel drive)
Problem: General Motors, LLC (GM) is recalling certain 2026 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL vehicles with four-wheel (4WD) or all-wheel drive (AWD), and certain 2015-2020 Suburban, Escalade, Escalade ESV, Yukon, Yukon XL, and Tahoe vehicles. A component missing from the drivetrain transfer case may cause the front and/or rear wheels to lock up without warning to the driver.
Risk: Front or rear wheel lockup increases the risk of a crash.
Fix: Owners are advised not to drive their vehicle until the remedy is completed. Dealers will inspect and, if necessary, replace the transfer case assembly, free of charge.

The affected tires were cured for too long during production.
Risk: Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.

Problem: General Motors LLC (GM) is recalling certain 2020 Cadillac Escalade, Escalade ESV, Chevrolet Camaro, Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles. The fuel pump may be missing a pressure regulator, allowing for over-pressurization of the fuel system.
Risk: Over-pressurization can crack the fuel pump and cause leaks, increasing the risk of a fire in the presence of an ignition source.
Fix: GM will notify owners, and dealers will replace the fuel pump, free of charge. The recall began December 18, 2019.

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.
