What the defect is
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 could happen
Damaged brake jumper wires can result in power brake assist failure, increasing the risk of a crash.
What gets fixed
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.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 6 November 2025.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
