2010-2012 Spartan RVs Recall 11V425: Exhaust Clamp

RN
Reviewed by the RecallNotify editorial team
Published June 2, 2026

Recall 11V425 covers 212 2010-2012 Spartan chassis vehicles with V-band clamp T-bolts that can fail. Free repair at authorized Cummins dealers.

Spartan is recalling 212 2010-2012 recreational vehicles, including Gladiator, K2, K3, Bus, Furion, Metro Star, and Mm models, because a V-band clamp T-bolt on the DOC/DPF exhaust assembly can fracture. If the clamp loosens, hot exhaust gases can escape before the tailpipe and create a fire risk; Spartan dealers will complete the repair free of charge once available.

What's wrong?

The V-band clamp assembly on affected 2010-2012 Spartan Gladiator, Mm, K2, K3, Bus, Furion, and Metro Star recreational vehicles holds parts of the diesel exhaust aftertreatment system together. It connects the inlet and outlet cone sections to the diesel oxidation catalyst and diesel particulate filter housing, the parts that help treat diesel exhaust before it leaves the vehicle.

The problem is the T-bolt inside that clamp. When the clamp is under stress or load, the T-bolt can fracture. Once that bolt breaks, the clamp loses holding force and the inlet or outlet section attached to the catalyst and filter housing can loosen or disconnect.

There is no warning sign before failure. An owner is unlikely to get a specific light, sound, or dashboard message that points to this clamp before the bolt breaks, so the VIN and dealer inspection matter.

Who's affected?

Spans 7 Spartan model lines from 2010-2012, all tied to engine and engine cooling.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.

What's the safety risk?

Disconnected inlet or outlet sections can vent hot exhaust before it exits the tailpipe, creating a risk of combustion and fire. If both clamps fail, the DOC and DPF housing can detach and become a road hazard. Schedule the repair soon. Repair will be free at any franchised Spartan dealer once available.

What should I do?

  1. Check your VIN to confirm your 2010-2012 Spartan Gladiator, Mm, K2, K3, Bus, Furion, or Metro Star is included in this recall.
  2. Contact Spartan customer service or Cummins to confirm the current repair path before scheduling service.
  3. Ask where an authorized Cummins dealer can perform the free V-band clamp repair that keeps the DOC/DPF exhaust sections secured.
  4. Bring the recall notice if you have it. If not, reference recall number 11V425 when you call.
  5. Avoid operating the vehicle if you smell hot exhaust, see loose exhaust parts, or suspect the DOC/DPF housing is not secure.

What happens at the repair

The source repair path says authorized Cummins dealers perform the recall work free of charge. At the dealer, the technician addresses the V-band clamp assembly that connects the inlet and outlet cone sections to the DOC and DPF housing. The work focuses on preventing a fractured T-bolt from loosening the clamp and allowing those sections to disconnect. The dealer repair will be free once available. The reimbursement plan is not stated in the recall record, so ask the service desk whether any prior related repair paperwork changes how your case is handled.
