Prevost Car (US) Inc. reported this defect to federal regulators on Feb 24, 2023 and put the number of vehicles at risk at 555. The repair is free for as long as the recall stands.
The 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.
The 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.
The 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.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 23V126000.
