The defect
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.
The risk
If the driver is not warned of a serious engine problem, the engine may unexpectedly fail, increasing the risk of a crash.
