Peterbilt and Kenworth Trucks Recalled for Defective Cummins Engines

The National Highway Traffic Safety Administration provided more information about a recall concerning Cummins diesel engines used in heavy duty trucks.

The agency said the engines were fitted in trucks from Peterbilt and Kenworth, all manufactured by Paccar, and several other vehicles.

The engines are equipped with a defective electronic system that could short circuit and blow a fuse. If this happens, not only could the engine stall but the driver would not be able to restart the truck. This could increase the risk of a crash, according to traffic safety regulators.

“The Engine Control Module (ECM) may develop an internal electrical short circuit that could possibly blow a fuse in the ECM’s electrical supply circuit, resulting in an engine stall without warning,” the NHTSA said.

The driver can only restart the engine once the ECM and fuse are replaced.

No injuries or crashes associated with this defect have been reported.

Paccar is recalling 3,227 vehicles equipped with Cummins ISX12 or ISX15 engines.

The affected trucks include 2017 Kenworth C500, T660, T680, T800, T880, and W900 vehicles produced between March 9 and April 26, and 2017 Peterbilt 320, 365, 367, 389, 567, 579, and 587 vehicles manufactured from March 10 to May 6.

The recall is expected to begin in August.

Spartan Motors USA is also recalling vehicles with defective Cummins ISX15 engines. These vehicles include 2017 Gladiator and K3 motorhome chassis produced between April 18 and June 7.

Dealers and owners have already been notified of the issue.
