The wheelchair platform bridging device may be too steep, which can cause the wheelchair to become unstable. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 403, "Platform Lift Devices" and 404, "Platform Lift Installations."

Consequence

An unstable wheelchair increases the risk of injury to lift occupants.

Prevost will replace the wheelchair lift bridging device, free of charge. Owner letters were mailed April 25, 2025. Owners may contact Prevost customer service at 1-866-870-2046. Prevost's number for this recall is SR24-26.

The red beacon lighting on the Threshold Warning System (TWS) may not be bright enough. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 403, "Platform Lift Systems."

Consequence

Beacons that do not provide proper illumination may be less visible to wheelchair lift users, increasing the risk of injury.

Remedy

Defect

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.

Consequence

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. Owner notification letters were mailed September 8, 2023. Owners may contact Prevost customer service at 1-866-870-2046. Prevost's number for this recall is SR23-05.

Defect

Prevost Car (US) Inc. (Prevost) is recalling certain 2010-2023 H3-45, H3-45 VIP, X3-45, X3-45 Com, and X3-45 VIP vehicles. In the event of the alternator front bearing seizing, the alternator belt may continue to operate, causing the bearing to overheat.

Consequence

An overheated alternator bearing can increase the risk of a fire.

Remedy

Consequence

The driveshaft connection may separate resulting in a loss of drive. Additionally, a section of the driveshaft may detach from the vehicle, becoming a road hazard. Either condition increases the risk of a crash.

Remedy

Prevost has notified owners, and will replace and properly tighten the driveshaft clamp bolts, free of charge. The recall began December 19, 2019. Owners may contact Prevost customer service at 1-866-870-2046. Prevost's number for this recall is SR19-43.

Defect

Prevost Cars, Inc. (Prevost) is recalling certain 2020 X3-45 VIP, X3-45 VIP Entertainer, X3-45 Passenger, H3-45 VIP, and H3-45 Passenger coaches. Due to a missing component, the driver may not be able to adjust the brightness of the dash illumination for the controls and indicators, allowing only the highest level of brightness. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 101, "Controls and Displays."

Consequence

During night time vehicle operation, highest level of dash brightness may reduce the driver's visibility, increasing the risk of a crash.

Remedy

Prevost will notify owners, and dealers will install the missing potentiometer component and required wiring to adjust the brightness of the dash's illumination, free of charge. The recall began November 28, 2019. Owners may contact Prevost customer service at 1-866-870-2046. Prevost's number for this recall is SR19-42.

Consequence

If the engine unexpectedly shuts down, passengers may have to be transferred to another vehicle on the side of the road, increasing the risk of an injury. If the engine unexpectedly shuts down while the vehicle is in motion, there is an increased risk of crash.

Remedy

Prevost will notify owners and will update the engine software, free of charge. The recall began December 19, 2019. Owners may contact Prevost customer service at 1-866-870-2046.
