GM Recall 2025: Chevy Silverado HD Fire Risk — What Every Owner Needs to Know
62 K+ Silverado 4500/5500/6500HD trucks from model years 2019–2024 may catch fire due to a leaking brake‑pressure sensor. Here’s the full story and how to stay safe.
Why Were These Trucks Recalled?
A rubber diaphragm inside the brake‑pressure sensor can break down, allowing brake fluid to travel along the wiring harness and short‑circuit the fused circuit. The result: overheating components and a potential engine‑compartment fire — even while the truck is parked and switched off.
Which Vehicles Are Affected?
- 2019–2024 Chevrolet Silverado 4500HD
- 2019–2024 Chevrolet Silverado 5500HD
- 2019–2024 Chevrolet Silverado 6500HD
GM reference: N242482680 · NHTSA Campaign: 25V‑390
How a Brake‑Fluid Leak Can Start a Fire
- Fluid enters the brake‑pressure sensor cavity.
- It migrates through the wiring harness to a fused circuit.
- A short circuit generates enough heat to ignite nearby materials.
Watch for warning signs: “Service Brake System” dash message, burning odor under the hood, or unusual brake‑assist pump sounds.
What Should Owners Do Right Now?
- Park outside and away from buildings until repairs are complete.
- Run your VIN through the NHTSA Lookup Tool or the GM Recall Center.
- Book service with any Chevrolet Commercial Truck dealer. Free towing is available if the truck isn’t safe to drive.
What Will the Dealership Replace?
Dealers will install a newly sealed brake‑pressure switch harness that blocks fluid migration. The fix is 100 % free and usually takes under two hours. Owner letters begin mailing July 28 2025.
