Recalls
Prevost Car (US) Inc. (Prevost) is recalling certain Prevost buses. Please see the above list of models. The entrance door is missing the emergency exit operating instruction label. As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) number 217, "Bus Emergency Exits and Window Retention and Release."
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.
