Recall 14V771 affects 80 2009-2011 Prevost X3 and XL2 coaches for a fire-suppression tank valve defect. Repair is free at any franchised Prevost dealer.
Prevost is recalling 80 2009-2011 X3 and XL2 coaches because the automatic fire suppression system pressure tank in the engine compartment has a pressure relief valve that can vent extinguishing agent after exposure to heat. If a fire occurs after the tank has vented, the system will not help extinguish it; Prevost dealers will complete the free repair.

What's wrong?
The automatic fire suppression system on 2009-2011 Prevost X3 and XL2 coaches uses a pressure tank mounted in the engine compartment. The tank stores extinguishing agent under pressure so the system can release it into the engine area if a fire starts. Its job is to keep that agent contained until the system needs it.
On affected coaches, the tank location exposes the pressure relief valve to engine-compartment heat. That valve is supposed to hold pressure under normal operating temperatures, but this placement can let the valve vent the extinguishing agent. Once the agent vents, the fire suppression system no longer has the same ability to control an engine-compartment fire. Prevost's repair relocates the tank.
There is no warning sign before failure. An owner or driver is not expected to see a light, hear a sound, or notice a change in drivability before the extinguishing agent vents.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
If the pressure tank has already vented before a fire, the fire suppression system is not functional to help extinguish that fire, increasing injury risk. There is no warning sign before this loss of function, so schedule the repair soon. Repair is free at any franchised Prevost dealer.
What should I do?
- Check your VIN to confirm your 2009-2011 Prevost X3 or XL2 is included in this recall.
- Contact a franchised Prevost dealer to schedule the free AFSS pressure-tank relocation that moves the tank away from engine-compartment heat.
- Bring the recall notice if you have it. If not, reference recall number 14V771 when you call.
- Call Prevost customer service at 1-877-773-8678 with questions about scheduling or the repair.
- Limit use until the repair is complete, since a vented AFSS tank will not help extinguish an engine-compartment fire.
What happens at the repair
At the dealer, a Prevost technician relocates the automatic fire suppression system pressure tank from the engine compartment area so the pressure relief valve is no longer exposed to that heat. The recall repair is free, and parts and labor are covered. Prevost has a general reimbursement plan on file for owners who already paid for this tank relocation or a related fire suppression tank repair. Bring repair orders, invoices, or payment records to the service desk, or contact Prevost customer service at 1-877-773-8678 to ask how to submit documentation.
