Recalls (4)
Power Train
criticalProblem: 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.

Electronic Stability Control (Esc)
highProblem: 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
highProblem: 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.
Seat Belts
highProblem: General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Risk: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
Fix: GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 18315.

Sources & method
Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). Floor 35. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Complaint counts and NHTSA crash ratings are shown separately and are not blended into the grade.
EPA figures come from fueleconomy.gov vehicle records (ids 39005, 39007, 39018, 39020). Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed weekly.
