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

EQUIPMENT:EMERGENCY:FIRE SUPRESSION:SENSORS
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.
