PACCAR issued a recall on the T600T800, and W900 models

On certain vehicles, the optional battery-mounted 50 amp and/or 60 amp circuit breaker had been wired incorrectly. If enough accessories are being used simultaneously during operation of these vehicles, this error in wiring can cause the cab power and engine to shut down prematurely without warning and could result in loss of vehicle control. Correction: Dealer will correct the electrical wiring if defect is found.
