Recall number 26V675000 · Recall details

What is wrong

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. 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.

Recall number 23V126000 · Recall details

the federal safety agency's Office of Defects Investigation (ODI) opened a Preliminary Evaluation after reviewing field reports concerning alternator front bearing failures that cause elevated temperatures within the engine compartment, resulting in the fire suppression system (FSS) activating, immediately shutting the engine down, and rendering the bus inoperable.Analysis of the data provided by Prevost Car (US) Inc. showed high failure frequency and thermal events. An immediate shutdown of the bus can increase the risk of a crash or injury of bus occupants. In response to this investigation, Prevost Car (US) Inc. and Volvo Bus Corporation decided to conduct recalls 22V‑221 and 22V‑222. By submitting Part 573 Defect Information Reports on April 6, 2022, Prevost Car (US) Inc. and Volvo Bus Corporation notified ODI of a safety defect in certain model year (MY) 2010-2023 Prevost H3-45; X3-45; X3-45 Com; H3-45 VIP: X3-45 VIP and 2020 Volvo 9700 vehicles; some of these buses may have experienced thermal events after failure of the alternator front bearing, because the alternator belt continues to turn the alternator after the bearing failure.These recall actions address the safety concern that led to the opening of this investigation.Therefore, with these recall actions, this investigation is closed. The recalls encompass all model and MY vehicles addressed by the investigation. However, the closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist in other model or MY vehicles outside of the recall scope. The agency reserves the right to take further action if warranted by the circumstances.
