Summary
Winnebago is recalling certain model year 2011 journey, meridian, tour, ellipse motor homes and winnebago commercial vehicles built on mc, xcl, and xcs chassis from September 1, 2010, through December 31, 2010, and equipped with a cummins isx or isl diesel engine. The v-band clamp assembly, part numbers Q187684, Q187685, and Q187686, used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (doc)/diesel particulate filter (DPF) include a t-bolt which can fracture and fail when subjected to stress or load. A fracture or failure of the t-bolt may cause the clamp to loosen and the inlet or outlet sections attached to the doc/DPF housing to disconnect.
Consequence
If the inlet or outlet sections disconnect, hot exhaust gases can vent prior to exiting the tailpipe, creating the risk of combustion and a fire. If both clamps fail, there is a risk in some applications that the doc/DPF housing may detach completely, creating a road hazard.
Remedy
Winnebago is working with daimler trucks north america (the supplier of the chassis) and cummins to identify and notify owners of the recall campaign. The manufacturer has not yet provided the agency with a remedy plan for this campaign. The safety recall began October 10, 2011. Owners may contact cummins at 1-812-377-5000.
Notes
Cummins' recall campaign number is C1154.OWNERS may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Winnebago been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Winnebago dealer can also check your VIN. Recall repairs are free.
