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.
- Engine#2022191
1,219 units affected
Issue: On certain vehicles, if the front bearing on the alternator fails, the alternator belts could continue to turn the alternator. This could cause the alternator bearing to overheat. Safety Risk: An overheated alternator bearing could create the risk of a fire. Corrective Actions: Prevost will notify owners by mail and instruct you to take your vehicle to a Prevost service center to replace the alternator belts. To reduce the safety risk, Prevost recommends that you should inspect the front bearing on the alternator regularly, and not operate the engine with a defective alternator.

U.S. NHTSA recalls
02- EQUIPMENT:EMERGENCY:FIRE SUPRESSION:SENSORS#23V126000
Prevost Car (US) Inc. (Prevost) is recalling certain 2018-2023 H3-45 motor coaches and H3-45 VIP motorhomes, and 2019 H3-41 motor coaches. The Automatic Fire Suppression System (AFSS) optical fire sensor positioned in the engine compartment's lower region may corrode and malfunction. In this event, the AFSS may give a false warning to the driver, command an unwarranted engine shutdown, and release a chemical fire extinguishing agent in the engine compartment.
Risk: The activation of the Automatic Fire Suppression System can cause a sudden loss of drive power, increasing the risk of a crash. Additionally, a disabled coach may require an evacuation procedure in an uncontrolled traffic situation, increasing the risk of injury to passengers.
Remedy: Prevost will inspect the vehicles, install spacers between the optical fire sensor and bracket, and replace the optical fire sensor, if necessary, free of charge.
