What's wrong?
The vehicle software on 2017-2018 Prevost X3-45 motorcoaches controls commands between the coach systems and the engine. One of those commands is the engine stop button in the engine compartment. That rear button is meant to let service personnel shut the engine off from the engine bay, without returning to the driver area.
On affected motorcoaches, a Prevost software development error left out the stop function while the engine is running. The button is still there, but the defective software versions do not send the command needed to stop the engine. The updated software adds that rear engine stop button function back into the coach.
There is no warning sign before failure. The issue shows up only when someone presses the engine stop button in the engine compartment and the engine keeps running.
