SERVICE BRAKES, HYDRAULIC:POWER ASSIST
- 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.
- What it can cause
- Damaged brake jumper wires can result in power brake assist failure, increasing the risk of a crash.
- What the dealer does
- 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.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

How this campaign compares
At 891 vehicles this is a bigger campaign than 57% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2019 to 2020, so the oldest vehicles on it were 6 model years old when the defect was reported to NHTSA.
Chevrolet vehicles have been recalled over the service brakes, hydraulic 52 times before this, most recently in June 2025 as 25V390000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry one other recall published here: 25V390000 (service brakes, hydraulic).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by General Motors, LLC with NHTSA on November 6, 2025 as campaign 25V768000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
