Defect and consequence

Defect: Prevost Car (US) Inc. (Prevost) is recalling certain 2014 and 2018 H3-41, 2013-2024 H3-45, 2012-2024 X3-45, and 2017-2023 X3-45 Commuter vehicles.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 403, "Platform Lift Systems.".

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

Remedy

Prevost will replace the red beacons, free of charge. Owner letters were mailed September 16, 2024. Owners may contact Prevost customer service at 1-866-870-2046. Prevost's number for this recall is SR24-03.

Defect and consequence

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.

Why it matters: 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.
