Recall 11V471 covers 5 2010-2011 Kme Predator and 5500 fire trucks for exhaust clamp failure. Repair is free through authorized Cummins dealers.
Kme is recalling 5 2010-2011 Predator and 5500 fire trucks because a V-band clamp T-bolt on the diesel oxidation catalyst and diesel particulate filter can fracture and loosen exhaust sections. Hot exhaust gases can vent before the tailpipe, raising fire risk, and the dealer repair will be free once available.

What's wrong?
The V-band clamp assembly on the 2010-2011 Kme Predator and 5500 fire trucks fastens exhaust sections to the diesel oxidation catalyst and diesel particulate filter housing. That housing is part of the diesel exhaust aftertreatment system, where exhaust passes through components that reduce emissions before it leaves the truck. The clamp uses a T-bolt to hold the inlet and outlet cone sections tight against the housing.
On affected trucks, the T-bolt in clamp assemblies Q187684, Q187685, and Q187686 can fracture when it is under stress or load. Once the bolt breaks, the clamp no longer holds the connection firmly. The inlet or outlet cone section attached to the DOC/DPF housing can loosen and disconnect from the housing.
There is no warning sign before failure. An owner or service department would not have a specific symptom to rely on before the clamp or exhaust section comes loose.
Who's affected?
Covers the Predator and 5500 across the 2010 and 2011 model years, tied to the same engine and cooling component.
| 2010 Kme Predator | Engine and engine cooling |
|---|---|
| 2011 Kme Predator | Engine and engine cooling |
| 2011 Dodge 5500 | Engine and engine cooling |
| Units affected | 5 |
A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
If the inlet or outlet exhaust sections disconnect, hot gases can vent before the tailpipe and raise the risk of combustion and fire. 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 Kme dealer once available.
What should I do?
- Check your VIN to confirm your 2010-2011 Kme Predator or 5500 is included in this recall.
- Contact Kme customer service or your Kme dealer to confirm current repair instructions for recall number 11V471.
- Ask whether an authorized Cummins dealer will perform the free V-band clamp repair that keeps the DOC/DPF exhaust sections secured.
- Bring the recall notice if Kme or Cummins mailed one, and give the dealer the campaign number when scheduling.
- Avoid operating the truck until the repair path is confirmed if you smell exhaust, see loose exhaust hardware, or suspect the DOC/DPF housing is not secure.
What happens at the repair
Kme worked with Cummins to notify owners of this campaign. Once the repair is available for a covered 2010-2011 Predator or 5500, an authorized Cummins dealer handles the recall work free of charge. The repair addresses the V-band clamp assembly on the Cummins ISX or ISL diesel engine exhaust aftertreatment system, where a fractured T-bolt can let the clamp loosen and allow DOC or DPF cone sections to disconnect. Parts and labor are covered under the recall.
