Chevrolet Recalls Heavy-Duty Trucks Due to Fire Hazard Reason
🎉 Scoop on the Chevy Pickup Recall! 🎉
Gear up for the latest automotive scoop! We're talking about a major recall involving Chevrolet's Silverado Medium Duty trucks, and it's quite a serious one.
General Motors (GM) recently announced a recall for approximately 62,500 Silverado 4500HD, 5500HD, and 6500HD models produced between 2019 to 2024. This recall, issued in June 2025, is a re-recall, stemming from an earlier campaign initiated in April 2023, addressing the same issue with brake pressure switches [1][2][4][5].
Here's what's happening: there's a potential leak in the brake pressure sensor assemblies, causing brake fluid to seep into the brake pressure switches. This brake fluid leak can lead to electrical short circuits, which in turn may activate the brake assist pump even when the brake isn't applied. The excess heat generated by this inadvertent activation could ignite an underhood fire [1].
As a precaution, GM advises owners to park their trucks outside and away from anything flammable until the issue is resolved. If your truck displays the "service brake system" warning light, it might indicate that brake fluid has already tainted the wiring harness, making the issue more pressing [1].
The issue appears to be rooted in a zinc-based sealing material used during assembly, which can deteriorate over time and obstruct the diaphragm separating the switch from its electronic components. While the seals themselves are not faulty, this debris interferes with the switch's components, causing the problem [1].
It's anticipated that this issue will affect less than 1% of the Silverado models assembled during certain production windows. Dealers will replace the brake pressure switch wire harness with a new design featuring a silicone sealant to prevent brake fluid leakage once they have the required replacement parts [1][2].
