NHTSA's recall notice
As NHTSA's recall record states it for campaign 18V555000.
Defect description
PACCAR Incorporated (PACCAR) is recalling certain 2016-2019 Kenworth C500, T660, T800, and W900 vehicles, equipped with 1.9M ISX15 engines. The engine harnesses may have been manufactured without check engine light (CEL) and stop engine light (SEL) circuits, preventing the driver from being warned of a serious engine problem.
Safety consequence
If the driver is not warned of a serious engine problem, the engine may unexpectedly fail, increasing the risk of a crash.
Manufacturer remedy
PACCAR will notify owners, and dealers will inspect or test the ISX15 engine harness, and install an overlay jumper harness to supply the missing CEL and SEL circuits, free of charge. The recall began November 30, 2018. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 18KWE.
