Silverado Engine Fire Recall: Everything Owners Need to Know

Urgent Alert: What You Need to Know About the Silverado Engine Fire Recall

As an automotive expert who has followed vehicle recalls for years, I can tell you that the latest Silverado engine fire recall is one you can’t afford to ignore. General Motors (GM) has issued this recall affecting roughly 62,468 2019-2024 Chevrolet Silverado Medium Duty trucks due to a serious fire risk under the hood.

This isn’t speculation — the Silverado engine fire recall was officially filed with the National Highway Traffic Safety Administration (NHTSA) under campaign number 25V390. If you own a 2019 to 2024 Silverado 4500HD, 5500HD, or 6500HD, you need to pay close attention.

Why the Silverado Engine Fire Recall Was Issued

Here’s what’s really going on. The root cause of the Silverado engine fire recall is a faulty brake pressure sensor assembly that can allow brake fluid to leak onto electrical components. That leakage can lead to a dangerous short circuit, overheating, and potentially a full-blown engine compartment fire — even if your truck is parked and turned off.

This defect affects some of the most popular medium-duty models:

2019-2024 Silverado 4500HD
2019-2024 Silverado 5500HD
2019-2024 Silverado 6500HD

If you see a “Service Brake System” warning light on your dashboard, that could be an early sign of this problem.

How the Silverado Engine Fire Recall Unfolded

I’ve reviewed the entire investigation process behind the Silverado engine fire recall, and here’s what happened:

1) November 24, 2024: GM launched a new product investigation after a 2023 Silverado experienced unintended brake pump activation — a vehicle not covered under the previous recall (23V-266).

2) December 2024: Another incident was reported with a 2021 Silverado that had already been repaired under the earlier recall, raising serious concerns.

3) Testing quickly confirmed that brake fluid was leaking into the wiring harness, causing electrical shorts.

4) By April 2025, lab analysis confirmed that the rubber diaphragm inside the brake pressure sensor was degrading. The culprit? An unauthorized chemical was used in the manufacturing process by supplier Kodiak Controls Inc. This chemical reacted with brake fluid, leading to internal leaks and posing a major fire risk.

5) GM ultimately uncovered 160 field reports potentially related to this issue, including one reported engine fire. Thankfully, there are no known injuries or accidents so far. Based on these findings, GM’s Safety Field Action Decision Authority approved the Silverado engine fire recall on June 5, 2025.

What GM Is Doing to Fix It

Here’s How the Silverado Engine Fire Recall Will Be Handled

GM dealers will:

• Replace the brake pressure switch wire harness with an upgraded part.

• The new harness features a silicone sealant that blocks brake fluid from seeping into electrical components.

• Even if your vehicle was repaired under the prior recall (23V-266), this new fix is still required — the previous remedy does not resolve this specific issue.

Important Safety Note

Until this repair is completed, GM urges owners to park their trucks outside and away from buildings or structures to prevent property damage in case of a fire.
