Paccar Inc. on April 6 issued a recall notice covering hundreds of thousands of trucks over concerns a blown fuse could prevent dashboard illumination.

The National Highway Traffic Safety Administration posted the recall notice after it was submitted by the Bellevue, Wash.-based truck maker. It covers 455,458 trucks that were manufactured between Jan. 10, 2007, and March 1, 2018.



Paccar said in the notice that a blown fuse could prevent dashboard illumination for anti-lock brakes or electronic stability control. The faulty fuse could increase the possibility of an accident if a driver is unaware of the issue, though the notice did not include reports of any such incidents.

“This recall is an outgrowth of an investigation performed in connection with 18V-368,” Paccar stated in the notice. “Further testing showed a larger population of vehicles was affected, and proposed remedies were not effective. A new testing matrix and a bench test were developed in September 2018.”

The industry is struggling to attract a new generation of technicians to maintain and repair increasingly high-tech trucks.

The tractor anti-lock brake system and electronic stability control lights might not illuminate without battery or ignition power to the ABS controller. Those warning lights therefore do not comply with rules covered by the Federal Motor Vehicle Safety Standards.

Paccar added that efforts to identify the affected chassis and develop a remedy started in late 2018. The recall covers trucks equipped with NAMUX software that included the 25% voltage threshold setting for the ABS/ESC malfunction in the indicator lamp.

The company in August 2018 had already recalled 85,626 trucks from the 2015-18 model years for a similar issue. Those trucks will have to have their software updated as the new recall notice citied issues with them as well.

Paccar stated the remedy consists of updating the NAMUX software within the cab control module, which the company will do for free. Dealers will be notified of the recall June 4, and customers on June 5.
