The defect is triggered by cold temperatures and there’s currently no solution for the problem.

Paccar has issued a recall for certain Kenworth trucks due to a defect that could cause the parking brake to fail, resulting in a crash or injuries.

The recall affects 1837 Kenworth T680 and T880 trucks model year 2018 – 2020 that are “equipped with a parking brake on a single axle and certain models of automated manual transmissions.”

According to recall documents, these trucks have a defect that could cause the parking brake to fail when the temperature drops: “During cold temperatures, the signal from the park brake pressure switch to the transmission controller may be delayed possibly resulting in the vehicle moving unexpectedly.”

Paccar has not yet developed a solution for the defect.

The recall is expected to start on June 3, 2019.

Truck owners can call PACCAR customer service at 1-918-259-3258 and reference recall number 19KWB.
