Navistar Inc. is recalling 1,191 heavy duty diesel trucks in the U.S. equipped with defective Cummins engines that could increase the risk of a crash.

The recall includes 2017 International ProStar, LoneStar, PayStar, HX and 9900 trucks produced between March and April.

These vehicles are fitted with Cummins ISX15L engines equipped with a defective electronic system that could short circuit and blow a fuse. The engine could then stall and the driver would not be able to restart the truck, thereby increasing the risk of a collision.

“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 National Highway Traffic Safety Administration said.

The engine can only be restarted once the ECM and fuse are replaced.

No injuries or crashes related to this issue have been reported.

The same defect has sparked several other recalls by truck manufacturers.

Paccar also recalled more than 3,000 Peterbilt and Kenworth trucks equipped with defective Cummins engines, and Spartan Motors USA recalled several vehicles as well.

Owners will be notified of the problem in August.

Navistar is also recalling several 2016 IC Bus RE school buses manufactured between Jan. 25 and March 31 due to a seating issue.

The buses are equipped with poorly attached seats that can separate from the base frame, which can increase the risk of passenger injury.

The manufacturer has already repaired the affected vehicles.
