Recall 12V033 affects 2 2011 Hme 1871 fire trucks for DOC/DPF clamp T-bolt failure. Repair will be free at any franchised Hme dealer once available.
Hme is recalling 2 2011 1871 fire trucks under recall 12V033 because a T-bolt in the diesel aftertreatment V-band clamp can fracture and let exhaust components separate. If the inlet or outlet section disconnects, hot exhaust gases can escape before the tailpipe and raise fire risk; the dealer repair will be free once available.

What's wrong?
The diesel oxidation catalyst and diesel particulate filter sit in the exhaust system on the 2011 Hme 1871 fire truck. They help process diesel exhaust before it leaves the vehicle. A V-band clamp assembly is the metal clamp that holds the inlet and outlet cone sections tight to that aftertreatment housing.
On the fire trucks in this recall, the clamp includes a T-bolt that can fracture when it is under stress or load. Once that bolt breaks, the clamp loses the tension that keeps the exhaust sections secured. The inlet or outlet section attached to the DOC and DPF housing can then disconnect.
There is no warning sign before failure. The first clear sign is the clamp or exhaust section coming loose, so the truck needs dealer inspection and repair if crews see a separated section or hear an exhaust leak near the aftertreatment housing.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Disconnected inlet or outlet sections let hot exhaust gases vent before the tailpipe, creating fire risk. If both clamps fail, the DOC/DPF housing can detach and become a road hazard. Schedule service promptly when the remedy is available, and stop using the vehicle if exhaust parts loosen or look damaged. Repair will be free at any franchised Hme dealer once available.
What should I do?
- Check your VIN to confirm your 2011 Hme 1871 is included in this recall.
- Review any Cummins or Hme owner notice for instructions before scheduling service.
- Contact a franchised Hme dealer and ask about the free Cummins DOC/DPF V-band clamp repair that secures the exhaust aftertreatment housing.
- Reference recall number 12V033 when you call, and ask whether Cummins is handling the appointment or parts for your truck.
- Drive only as needed until the truck is inspected. Stop in a safe place if you smell hot exhaust, see smoke, or hear exhaust parts loosen.
What happens at the repair
Hme and Cummins are coordinating owner notification and repair details for the Cummins engine equipment on the 2011 1871 fire trucks. The repair is expected to address the V-band clamp assembly and T-bolt that secure the inlet and outlet cone sections to the DOC/DPF housing. Once the final dealer repair is available, parts and labor will be free under the recall. For repair coordination, contact Cummins at 1-812-377-5000 and have the VIN ready.
