Lisle, IL – May 13, 2023 – Navistar is recalling 9,170 2017 – 2023 International CV heavy-duty pickup trucks because the electric components in their brake systems may short-circuit and catch fire. This increases the risk of a crash and injury. In addition, the vehicle may burst into flames even when parked, causing property damage.
When the driver presses the brake pedal, the movement is transferred to a brake booster, which multiplies braking force, as reported. Listed trucks are also equipped with a brake pressure switch, which detects when the brake is applied. This is necessary for brake light activation and the operation of various driver assistance systems.
The brake switch in the affected vehicles has a design flaw that could cause the seal between the brake booster and pressure switch to deteriorate. If this happens, the brake fluid could leak into the switch, which might short-circuit and overheat.
All fire-related risks are described in this recent GM recall, which affected heavy-duty trucks that have the same brake pressure switch, as reported. The GM vehicles in question were made by Navistar.
A short-circuited brake pressure switch could trigger a “Service Brake System” warning on the vehicle’s display.
As described in the said recent Chevy recall, you and all the passengers should quickly yet safely leave the vehicle if it catches fire while driving. This includes pulling over at a first safe spot and getting away from the vehicle while also being careful not to get hit by other cars.
In addition, due to the nature of the defect, the truck may burst into flames even when it is parked with the engine off. Because of this, it’s strongly recommended to park it in the open and away from other cars and structures until the repair is done.
Other Navistar recalls
In December 2022, Navistar recalled some of its trucks and buses, including International CVs, over a risk of steering loss and vehicle instability.
This was not the only problem with stability this manufacturer had recently, as some of its school buses were recalled in January 2023 over potential loss of control.
Dealers will replace the leaking brake pressure switch with an upgraded variant. In addition, the connecting wiring harness will also be replaced if the brake fluid is found in its connector. The repairs are free of charge.
Owners should receive letters with more information starting on June 19, 2023.
