What's wrong?
The rear battery compartment in a 2022 Demers MXP153E ambulance is part of the rear patient module. It houses the battery and includes a ventilation hole so air can move through the compartment instead of being trapped around the battery. That opening is part of the body structure, not a wear item.
On the affected ambulances, that ventilation hole was left out after a production drawing revision for the rear module. Without the opening, the compartment is not built as designed. The problem is structural and visible during inspection: the compartment wall lacks the hole that should be present.
There is no warning sign before failure. An owner or service technician should not rely on a light, sound, smell, or driving change to find this defect. The check is a direct visual inspection of the rear battery compartment.
