- The problem
- On certain motor homes built with cummins isl cm850 diesel engines, the connecting rod contains a machining defect in the wrist pin bushing of the rod that could cause a seizure of the piston pin.
- The risk
- If allowed to progress, this can lead to engine failure with the possibility of the rod rupturing the lock cavity, spilling oil and debris onto the roadway increasing the risk of a crash.
- The fix
- Winnebago is working with cummins to recalibrate the engine control module and enhance the engine protection system enabling it to provide early detection of the failure mode and avoid more serious engine damage and resultant safety hazard. Cummins will also install a new valve cover with a crankcase pressure sensor free of charge (please see 07e033). Owners may contact cummins at 1-800-343-7357 or winnebago at 641-585-3535.

Engine recalls for the 2007 Itasca Horizon
Engine complaints
This complaint is about the cummins isl engine failures. A light on our dash pinged and flashed. I called freightliner and was told it was a stop engine light. I was told it was probably a "glitc" and it was okay to drive. However, we took it into a freightliner/cummins repair facility to just check it out. They found that the oil pressure was fine, no problem with the sending unit, or the dash instrument cluster, so they dropped the oil pan. They found that a thrust bushing had fallen off one of the crankshaft...

bearings and 2 of the main bearings had spun out. Had we not stopped and taken the coach in to be looked at, that engine would have blown apart on the highway and possibly killed someone and definitely would have caused major damage to the coach. These cummins engines have already been recalled once, but the engine serial numbers need to be extended. My engine falls just outside the recall numbers.
