What's wrong?
In recall 21V740, the oxygen network and roof harness sit above the patient compartment headliner on 2020-2021 Demers Ambulances MXP153 Dodge Ram and MXP153 Ford F-Series ambulances. The oxygen tubing carries medical oxygen to outlets in the patient area, while the roof harness carries electrical power and signals for equipment mounted in or near the ceiling. Both need open clearance so the tube and wires are not squeezed by the ceiling structure.
On the affected ambulances, the hose and wiring were routed too close to ceiling spacers and reinforcements. That tight clearance pinches the medical oxygen tube and electrical wires above the headliner. The defect is in the routing space, not in how the ambulance is driven or used.
There is no warning sign before failure. Because the parts are hidden above the headliner, an owner or crew member is not expected to see the damage before inspection or repair.

What happens at the repair
At the dealer, a Demers Ambulances technician removes the ceiling panels and spacers, replaces the affected wires and oxygen network tubing, and creates a routing channel inside the insulation board so the wires have proper clearance. Parts and labor are free under the recall. If this defect was fixed before the recall was released, Demers Ambulances reimburses the customer or dealer for material and labor. Ask the service desk or Demers Ambulances customer service how to document the earlier repair costs.
