What's wrong?

The exhaust system on 2011-2016 Glaval Bus Titan Ii buses carries hot engine gases from the diesel engine to the tailpipe. It also handles the extra heat produced during diesel filter regeneration, when the system burns soot out of the filter. That heat has to stay inside the exhaust tubing and away from the floor structure.

On affected buses, a floor-decking screw used during assembly pierced the exhaust tube. When the screw was removed, it left a hole in the exhaust path. Hot exhaust gases then escaped upward through that opening and into the floor area, where they burned through the floor decking. The recall repair checks the exhaust system and flooring for any hole, then replaces the exhaust system or seals it with an approved repair kit.

The warning sign is smoke entering the occupant area from the exhaust tube under the vehicle. Treat that as a sign that hot exhaust is reaching the floor area and the bus needs inspection.

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?

If the exhaust tube is pierced and the screw is removed, exhaust fumes can enter the passenger area, and fire risk increases. Smoke inside the bus is the warning sign. Stop using the bus and call the dealer if smoke appears. Repair is free at any franchised Glaval Bus dealer.

What should I do?

  1. Check your VIN to confirm your 2011-2016 Glaval Bus Titan Ii is included in this recall.

  3. Bring the recall notice if Glaval Bus has mailed one. If not, reference recall number 15V596 when you call.
  4. Stop using the bus if exhaust fumes enter the passenger area, and ask the dealer about towing before moving it.

What happens at the repair

At the dealer, a Glaval Bus technician removes and inspects the exhaust system, then seals the exhaust tube or replaces the affected exhaust parts if inspection shows damage. The recall repair is free, with parts and labor covered. Glaval Bus has a general reimbursement plan on file for this campaign. If you've already paid out of pocket for this exhaust-system repair, bring your repair paperwork and receipts to the service desk so the dealer can explain the reimbursement claim process.
