Park itPower Train · 26V289000
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. Owner notification letters were mailed May 18, 2026. Owners may contact GMC customer service at 1-800-462-8782, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-333-4223. GM's number for this recall is N262557620.

Tires · 21V115000
General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT4, XT5, Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, Traverse, GMC Yukon, Yukon XL, 2018-2021 Chevrolet Express, GMC Savana, 2019-2020 Chevrolet Blazer, Silverado 1500, GMC Acadia, Sierra 1500, and certain Continental tires sold to the aftermarket for various model year 2018-2021 vehicles. 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.
Fix: GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.

Fuel System, Gasoline · 19V837000
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. Owners may contact Cadillac customer service at 1-800-333-4223, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-888-988-7267. GM's number for this recall is N192283991.
Service Brakes, Hydraulic · 19V761000
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.
Questions to ask the seller
Questions worth asking the seller of this GMC before you buy, drawn from its public record:
- NHTSA lists 4 recall campaigns for the 2020 GMC Yukon Denali. Can you run this car's VIN at nhtsa.gov/recalls and confirm each one shows "Remedy Completed"? One is a "park it" / "park outside" order, the most serious kind, so I'd want that repair documented before I drive it.
- Owners of this model report transmission & drivetrain problems more than anything else. Has this car shown any transmission & drivetrain symptoms, and are there repair records for it?
- Owners of this model report engine problems more than anything else (owners tend to report it near 67k miles). Has this car shown any engine symptoms, and are there repair records for it?
- Has this car been in any accident or had any structural, airbag, or flood-related repair? Do you have a clean title and a recent history report (Carfax / AutoCheck)?
- How many owners has it had, do you have the maintenance records, and why are you selling it?
- Are you open to me having an independent mechanic inspect it before we settle on a price?
