What owners report

  • Transmission valve body failures cause hard shifts, jerking, loss of motive power, and low-power mode, sometimes leaving the truck undrivable for weeks.
  • Some owners report the check engine light and an unfamiliar orange warning light illuminating alongside abnormal engine noise or odor before the vehicle loses power.
  • The trailer brake warning light stays on and cannot be resolved after multiple dealer visits, affecting trailer braking function.
  • The rearview camera's split-screen display intermittently distorts or goes blank while backing up.
  • A fractured rear sliding window track allowed water to leak into the rear seat area.
  • The parking brake shoe lining came unbonded from the shoe, discovered when the dealer inspected the rear brakes.

    Latches/locks/linkages:tailgate:latch

    General Motors, LLC (GM) is recalling certain 2020-2024 Chevrolet Silverado 2500, 3500, GMC Sierra 2500 and 3500 vehicles equipped with power-unlatching tailgates. The tailgate's electronic gate-release switch may short circuit due to water intrusion, which can result in the tailgate inadvertently unlatching while the vehicle is in park.

    Risk: An unlatched tailgate may open while driving and result in a loss of unsecured cargo, creating a road hazard and increasing the risk of a crash.

    Remedy: Owners are advised to check that the tailgate is closed and latched before driving. Dealers will replace the exterior touchpad switch assemblies, free of charge. Owner notification letters were mailed May 17, 2024. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232426400.
