General Motors (GM) issued a recall after discovering that brake fluid can leak into the brake pressure switch, potentially causing damage under the car hood even when the vehicle is off, according to a June 23 recall report from the National Highway Traffic Safety Administration (NHTSA).

The vehicles affected include certain 2019-2024 Chevrolet Silverado medium duty 4500HD, 5500HD, and 6500HD models. Vehicles from model years before 2019 have a different design and are not included in this recall.

The issue is that the brake pressure sensor assembly may allow brake fluid to leak past the diaphragm seal and into the brake pressure switch. This leakage can reach the sensor's electrical components, potentially causing a short circuit in the brake pressure switch and its corresponding fuse.

If brake fluid shorts the brake pressure switch and the associated fuse, the circuit can generate excessive heat that could result in a fire, increasing the risk of injury. An underhood fire could occur when the vehicle is turned off and unattended.

Owners are advised to park their trucks outdoors until the recall remedy is performed, the NHTSA said. This issue may also show a “service brake system” malfunction indicator lamp on the vehicle.

The cause of the issue is traced back to an unauthorized chemical that was used by the supplier in the manufacture of a rubber diaphragm in the brake pressure sensor assembly. The chemical used can cause the diaphragm to degrade over time. The supplier, Kodiak Controls Inc., is based in the United States.

This issue is separate from, but related to, a 2023 recall (23V-266) that addressed a problem with zinc sealant in brake pressure sensors, according to NHTSA. Despite improved sensor designs meant to resolve the earlier defect, field reports in late 2024 and early 2025 revealed fluid intrusion in newer and previously repaired vehicles.

Lab testing revealed that the root of the issue was the unauthorized chemical breaking down the diaphragm seal rubber. GM confirmed 160 related reports, and one fire has been reported. General Motors is not aware of any accidents or injuries related to this condition. On June 5, 2025, GM’s safety board approved a new recall to address the defect.

GM plans to send out interim notifications to owners starting July 28. GM will later let owners know once a repair becomes available.

The NHTSA recall number is 25V390. The manufacturer’s recall number is N242482680.

This is the latest recall from GM, which issued another recall in April for some Cadillac, Chevrolet, and GMC models due to potential defects that could affect the engine. A manufacturing defect in the connecting rod and crankshaft could lead to engine damage or failure. Nearly 600,000 SUVs and trucks were included in that recall, but only 3 percent had the malfunction, according to GM at the time.
