On certain vehicles, the fire sensor located in the engine compartment could fail. If this happens, the automatic fire suppression system (AFSS) could activate and shut down the engine.
Safety Risk
A sudden loss of engine power could increase the risk of a crash.
Corrective Actions
Prevost will notify owners by mail and instruct you to take your vehicle to a Prevost service center to inspect, and if necessary replace the fire sensor. They will also install spacers between the sensor and mounting bracket.
