The defect
General Motors, LLC (GM) is recalling certain 2019-2020 Chevrolet Silverado Medium Duty 4500HD, 5500HD, and 6500HD vehicles. These vehicles were remedied under NHTSA Recall 25V390 with a brake jumper wire harness that was assembled without protective tape. A wiring harness that is missing protective tape can allow the wires to become damaged.
The risk
Damaged brake jumper wires can result in power brake assist failure, increasing the risk of a crash.
The remedy
Dealers will remove the installed wire harness, apply protective tape, and reinstall the wire harness, free of charge. Owner notification letters are planned to be mailed December 22, 2025. Owners may contact GM customer assistance number at 1-866-467-9700. GM's number for this recall is N252531990. Vehicles in this recall were previously repaired under 25V390 and will need to have the new remedy completed. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov beginning November 6, 2025.
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
