On April 14, 2026, a GM engineer submitted a report to GM’s Speak Up For Safety (SUFS) program following review of teardown results on a transfer case from a 2026 Chevrolet Silverado 1500 that experienced wheel lock-up in a parking lot. The transfer case was missing the oil pick-up tube. Without this tube, transfer case bearings will not be properly lubricated. The transfer case is a component of four-wheel-drive and all-wheel-drive powertrains and is not present on rear-wheel-drive only vehicles. GM opened a product investigation on April 17, 2026.

GM’s supplier used their end-of-line test torque data to identify suspect transfer case assemblies. This process identified 68 suspect assemblies, of which: (a) 46 were assembled into 2026 model year US production vehicles and (b) one was shipped as a service replacement transfer case assembly for use in certain 2015 – 2020 model year trucks and SUVs. GM’s investigation identified 54 dealers that may have received the suspect service part, and 21 potentially impacted vehicles that received a transfer case replacement at these dealerships during the suspect window.

GM’s investigation identified four field complaints potentially related to this condition. GM is not aware of any crashes or injuries associated with this condition. GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall on April 30, 2026.

More details of the recall are available on the NHTSA website.
