What's wrong?
The hazard warning lights on 2022-2023 Prevost H3-45 Vip and H3-45 buses are controlled by vehicle software. That software tells the turn signal lamps to flash together when the hazard switch is turned on, including when the ignition is off. FMVSS 108 requires that behavior so the bus stays visible as a stopped or disabled vehicle.
On affected buses, a Prevost software development error interrupts that command when the ignition is off. The hazard switch still activates the system, but the turn signal lamps do not flash simultaneously. The updated software corrects the command so the lamps flash together with the ignition set to off.
There is no warning sign before failure. An owner or driver would notice the issue only by activating the hazard warning lights with the ignition off and seeing that the turn signal lamps are not flashing together.
Who's affected?
Covers both H3-45 Vip and H3-45 buses across the 2022 and 2023 model years, all tied to the same hazard-light software component.
