General Motors (GM) has announced a major recall affecting nearly 62,000 vehicles due to the GM Vehicle Recall Fire Risk linked to a critical brake defect. This recall targets specific 2019–2024 Chevrolet Silverado Medium Duty models, including the 4500HD, 5500HD, and 6500HD variants.
According to the National Highway Traffic Safety Administration (NHTSA), a fault in the brake pressure sensor may cause fluid leakage, which can result in electrical shorts and potential underhood fires—even when the truck is turned off. Due to the rising concerns around the GM Vehicle Recall Fire Risk, Silverado owners are being urged to park their trucks outdoors and away from buildings until free repairs are completed.
GM Vehicle Recall 2025: What’s Happening and Why It Matters
In 2025, General Motors announced a major safety recall affecting over 62,000 Chevrolet Silverado Medium Duty trucks manufactured between 2019 and 2024. The issue centers around a brake pressure sensor assembly that can leak fluid, increasing the risk of an electrical short circuit. This short can overheat, potentially causing a fire—even when the vehicle is parked and turned off.
According to the National Highway Traffic Safety Administration (NHTSA), the faulty component was linked to the use of an unauthorized chemical during production, which caused internal degradation over time. While GM believes only around 1% of the recalled vehicles may actually have the defect, the fire hazard is serious enough that owners are strongly advised to park outdoors and away from buildings until the repair is completed.
Dealers will replace the affected brake switch wiring harness at no cost to customers. Notification letters will begin going out by July 28, 2025, and appointments can be scheduled through authorized Chevrolet service centers.
This recall underscores the importance of strict quality control in vehicle manufacturing—especially when it comes to safety-critical components like braking systems. For Silverado owners, it’s a reminder to stay informed and act quickly when official recall notices are issued.
What Is the Brake Fire Risk in GM Vehicles?
The recent GM vehicle recall fire risk is linked to a faulty brake pressure switch issue in certain 2019–2024 Silverado Medium Duty trucks. Brake fluid may leak into the switch, causing an electrical short that could trigger a fire—even when the engine is off. This defect affects a small percentage of vehicles but poses a serious safety risk, prompting GM to advise owners to park their trucks outdoors until repairs are completed.
Which Chevrolet Silverado Models Are Affected in the Recall?
The ongoing GM vehicle recall fire risk affects specific Chevrolet Silverado 4500HD, 5500HD, and 6500HD models manufactured between 2019 and 2024. These Medium Duty trucks may have a defective brake pressure switch that allows fluid to leak into the electrical system, increasing the chances of an under-hood fire—even when the truck is parked. Although GM reports that only about 1% of the 62,000 recalled vehicles are likely to be affected, the safety risk is significant enough to urge owners to park their trucks outside until the repair is complete.
Why Did the Brake Assembly Fail?
The recent GM vehicle recall fire risk has been traced back to a specific failure in the brake pressure switch assembly. This component, which plays a critical role in regulating braking systems, began to degrade due to the use of a non-approved chemical in the sealing material supplied by a third-party vendor. Over time, this chemical caused the rubber diaphragm inside the switch to weaken, leading to small leaks of brake fluid. Once the fluid made contact with the electrical terminals inside the switch, it created the potential for short circuits, which could generate excessive heat and, in rare cases, result in an engine compartment fire—even when the vehicle was not running. This failure wasn’t immediately detectable during normal maintenance, making it even more dangerous for unsuspecting Silverado owners. Though only about 1% of the affected Chevrolet Silverado 4500HD, 5500HD, and 6500HD models are expected to have the defect, the fire risk is severe enough for GM and safety authorities to act swiftly. As a result, the company is offering a no-cost replacement of the faulty wiring harness to eliminate the hazard.
