A recall announced recently by Paccar affects more than 11,000 Kenworth tractors, while other recalls were also announced recently by Volvo, Mack and Mac Trailer, according to documents from the National Highway Traffic Safety Administration.

Paccar’s recall, affecting approximately 11,429 vehicles, stems from engine harnesses for trucks equipped with ISX15 engines that may have been manufactured without check engine light and stop engine light circuits, which could prevent the driver from being warned of a serious engine problem. Affected trucks, manufactured between July 23, 2015, and Aug. 17, 2018, include:

  • 2016-2019 Kenworth C500
  • 2016-2019 Kenworth T660
  • 2016-2019 Kenworth T800
  • 2016-2019 Kenworth W900

Paccar will begin notifying owners on Oct. 19, and dealers will inspect or test the ISX15 engine harness and install an overlay jumper harness to supply the missing circuits. Owners can contact Paccar customer service at 1-918-259-3258 with recall number 18KWE. NHTSA’s recall number is 18V-555.

Volvo Trucks and Mack Trucks each issued a recall for a problem with the fifth wheel on certain tractors. The recalls affect 69 model year 2019 Volvo VNL and VNR and nine 2019 Mack Anthem trucks equipped with Jost fifth wheel couplings. These fifth wheels may have a slider bracket that is too narrow, possibly allowing a trailer to separate from the tractor.

Volvo and Mack began notifying owners on Sept. 14. Dealers will inspect the fifth wheel slider bracket and replace it if necessary. Owners of affected trucks can contact Volvo customer service at 1-800-528-6586 with recall number RVXX1801, and Mack owners can contact customer service at 1-888-866-1177 with recall number SC0411. NHTSA’s recall numbers are 18V-542 for Volvo, and 18V-543 for Mack.

The recall from Mac Trailer affects approximately 429 model year 2019 dump and waste trailers. The wheel end nut locking device on these trailers may not be properly installed, allowing the wheel end to separate from the axle.

Mac Trailer will begin notifying affected trailer owners this month, and dealers will inspect the locking nut to ensure it is properly installed. Owners can contact Mac Trailer customer service at 1-888-327-4236 with recall number 10-70-001 2018. NHTSA’s recall number is 18V-567.
