If heat damages that wiring, the system can activate and shut down the engine, increasing crash risk; Prevost dealers will complete the recall repair free of charge.

What's wrong?
The Automatic Fire Suppression System on 2010-2014 Prevost X3-45, H3-41, H3-45, and XLII-45 coaches is built to detect dangerous heat in the engine compartment. Its Linear Thermal Detector uses wiring routed through that area to sense heat and send the signal the system needs before it responds.
On affected coaches, the LTD wires sit where engine compartment temperatures can damage them. Heat can degrade the wiring, which interferes with the detector's ability to carry the signal correctly. Prevost's repair relocates those wires so the detector wiring is kept away from the damaging heat path.
The driver will receive an alert before engine shutdown. That alert is the warning sign available to the driver, and it should be treated as a sign that the fire suppression system needs service attention.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Damaged AFSS LTD wiring can activate the AFSS and shut down the engine, increasing crash risk. The driver receives an alert before engine shutdown, so treat that alert as a reason to pull over safely and contact a Prevost dealer. Repair is free at any franchised Prevost dealer.
What should I do?
- Check your VIN to confirm your 2010-2014 Prevost X3-45, H3-41, H3-45, or XLII-45 coach is included in this recall.
- Contact a franchised Prevost dealer to schedule the free AFSS LTD wiring relocation that moves the fire-suppression detector wiring away from engine-compartment heat.
- Ask the dealer how to handle the coach if the AFSS activates or the engine shuts down before the repair.
- Bring the recall notice if Prevost mailed one. If not, reference recall number 15V348 when you call.
- Call Prevost customer service at 1-800-463-7738 with recall questions.
What happens at the repair
At the dealer, a Prevost technician relocates the AFSS LTD wiring so engine compartment heat is no longer positioned to damage the linear thermal detector wiring. Parts and labor are free under the recall. If you already paid for an AFSS LTD wiring repair before the recall notice, Prevost handles reimbursement case by case under Volvo Trucks' general reimbursement plan. Bring repair invoices and payment records to the service desk or ask Prevost customer service to review the claim.
