24V-060 · LATCHES/LOCKS/LINKAGES:TAILGATE:LATCH
General Motors, LLC · Filed February 1, 2024
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.
What can happen. 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.
The repair. 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.

Sierra 2500 transmission valve body faults on 2023 and 2024 trucks
Years: 2023, 2024
NHTSA complaint ODI 11759764, on a 2024 GMC Sierra 2500, says the control valve body failed, the truck went into limp mode at 34,000 miles, and the shop had many of the same year waiting on the same repair. Complaint ODI 11711040 says the transmission made a loud noise and speed dropped in traffic, the truck had to be towed, and the initial diagnosis was the valve body. On a Duramax forum list of 10L1000 failures, a 2023 Sierra 2500HD owner writes that the truck gave what the post calls a shutter from 5th to 6th and from 6th to 7th, set codes P0700 and P0747, downshifted to 5th, and would not leave 5th. The owner describes pavement miles and very light towing, at 34,000 miles, with a build date of January 14, 2023. A later post says the valve body arrived and the truck was fixed on July 23, 2025. The same list includes 2024 Chevrolet Silverado 2500HD and 3500 reports of limp mode and valve-body replacement, including one 2024 3500 that banged while towing a 24,000-pound RV. NHTSA complaints on the 2024 Silverado 2500, including ODI 11673856, describe a valve-body diagnosis while towing, with codes P0747 and P0700.
