Paccar is recalling 1,222 heavy-duty diesel trucks because of a software defect that allows the engines to start when the transmission is in gear, causing unexpected movement that could increase the risk of a crash.
The recall includes 2018 Kenworth T680 and T880 trucks, built between June 19 and Dec. 19, 2017. Peterbilt 567 and 579 vehicles built between May 1 and Dec. 22, 2017 also are included.
The affected vehicles are equipped with Eaton Endurant and Paccar AMT transmissions with faulty transmission control module software. The vehicles can start even if the shifter is not in the neutral position.
“The vehicle may move without warning if the engine starts or attempts to start without the parking brake or service brake applied,” the National Highway Traffic Safety Administration said.
Dealers will reprogram the transmission control modules with the corrective updated software in the affected Kenworth and Peterbilt trucks that “prevents the engine starter from engaging until the shift stalk reports that it is in neutral,” NHTSA said.
Owners will be notified on Feb. 16.
