The Defect Behind the Brake Pressure Switch Recall
The core issue involves the brake pressure sensor assembly, which may leak brake fluid into the brake pressure switch.
When this happens, it can cause an electrical short circuit, increasing the risk of a fire whether the vehicle is in motion or parked.
The defect may be linked to residual brake fluid trapped in the wiring harness, possibly due to improper service procedures tied to a prior recall (23V282).
In certain situations, the fluid can wick through the harness, leading to overheating and creating a fire hazard.
Until repairs are completed, owners are advised to park their vehicles outdoors as a precaution against potential fire risks.
Which Silverado Models Are Affected?
The brake pressure switch recall affects Chevrolet Silverado Medium Duty trucks, including:
- 4500 HD (2019–2024)
- 5500 HD (2019–2024)
- 6500 HD (2019–2024)
Models built before 2019 are not affected. Certain 2024 models with a silicone-sealed brake switch wire harness are also excluded from the recall.
Previous Silverado Brake Pressure Switch Recalls
A previous recall released in April 2023 (Recall N222375270) involves the brake pressure switch on Chevrolet Silverado Medium Duty (MD) trucks.
GM identified that the brake pressure sensor assembly could leak brake fluid into the brake pressure switch.
This leakage risked causing an electrical short, which significantly increased the chance of fire. This recall covered 2019–2023 Silverado 4500 HD, 5500 HD, and 6500 HD models.
The root cause was traced to a faulty rubber diaphragm seal in the pressure sensor, possibly linked to the use of an unauthorized chemical during manufacturing.
The remedy involved inspecting and replacing the brake pressure switch and wiring harness as needed.
GM’s Official Remedy and Repair Plan
The official plan involves replacing the brake pressure switch and the entire wiring harness with a new version that features a silicone sealant to prevent brake fluid from wicking into electrical components.
In some cases, the master cylinder pressure sensor will also be inspected and replaced if needed. Because of the fire risk posed by this defect, GM advises owners to park their vehicles outdoors and away from structures until repairs are completed. All repairs will be provided free of charge.
GM will begin sending interim notification letters to owners by July 28, 2025, informing them of the safety risk.
Final letters with instructions to schedule repairs will be mailed once parts become available. Additionally, a stop-sale order is currently in effect for unsold vehicles covered by this recall.
Until your vehicle is repaired, take immediate safety precautions by parking it outdoors away from buildings or flammable materials and avoid leaving it idling unattended, especially in enclosed spaces like garages.
