Eldorado is recalling 22 commercial buses from the 2004, 2011 model years, including Ez Rider Ii Max, Transmark, Xhf, and Axess models, because a V-band clamp T-bolt on the diesel oxidation catalyst or diesel particulate filter can fracture.

What's wrong?
On the 2004, 2011 Eldorado Ez Rider Ii Max, Transmark, Xhf, and Axess buses in this recall, the V-band clamp assembly holds exhaust aftertreatment sections together. It connects the inlet and outlet cone sections to the diesel oxidation catalyst and diesel particulate filter housing. Those parts clean diesel exhaust before it leaves the bus.
The weak point is the T-bolt inside the clamp assembly. Under stress or load, that bolt can fracture and fail. Once the bolt breaks, the clamp loses its grip. The inlet or outlet cone section attached to the DOC/DPF housing can then loosen and disconnect.
There is no warning sign before failure. After the clamp loosens, a driver or technician can notice an exhaust leak, unusual exhaust noise, or visible separation around the DOC/DPF housing.
Who's affected?
Covers Ez Rider Ii Max, Transmark, Xhf, and Axess buses across the 2004 and 2011 model years, all involving the engine and cooling system.

What's the safety risk?
NHTSA campaign 11V432 says disconnected exhaust sections let hot exhaust gases vent before the tailpipe, creating a fire risk. If both clamps fail, the DOC/DPF housing can detach and become a road hazard. Schedule the recall repair soon. Repair will be free at any franchised Eldorado dealer once available.
What should I do?
- Check your VIN to confirm your 2004 or 2011 Eldorado Axess, Ez Rider Ii Max, Transmark, or Xhf is included in this recall.
- Contact Eldorado or an authorized Cummins dealer for the free V-band clamp repair that keeps hot exhaust gases inside the DOC and DPF housing.
- Bring the recall notice if you have it. If not, reference recall number 11V432 when you call.
- Avoid operating the bus if you smell exhaust heat, see loose exhaust hardware, or notice the DOC or DPF housing moving out of place.
- Call Cummins at 1-812-377-5000 with repair questions before arranging service.
