On certain motorhomes, the liquid propane (LP) hose could rub on the bottom metal plate of the Norcold refrigerator, and may develop a leak. Leaking propane in the presence of an ignition source could result in an explosion or fire causing injury and/or damage to property.

Also, the nozzle may detach from the valve assembly with enough force that it could cause injury, and fail to discharge. In case of fire, failure of the extinguisher to function could result in injury and/or property damage. Correction: Owners will be provided with instructions on how to inspect the fire extinguisher to see if it is recalled. Replacement fire extinguishers will be supplied by Kidde directly.

On certain motorhomes equipped with Lippert Components Inc. electric entry steps, an internal bolt on the steps that attaches the fan gear assembly to the steps could fracture. This results in the fan gear disengaging from the steps, which could cause the steps to stop in an unexpected position and appear to be loose or unstable. If the steps become unstable, it could cause a person to fall, resulting in injury. Correction: Dealers will install a step retainer bracket to reinforce the operating mechanism, and all bolts of the mechanism will also be replaced.
- Label#2015159

Correction: Updated labels will be mailed to owners of affected vehicles along with instructions for proper installation.

- Engine#2011117
66 units affected
On certain motorhomes, wiring for the catalytic converter's oxygen sensor may not be properly secured. As such, the wiring may contact the exhaust and melt/short, which could result in Check Engine Light illumination and, in some instances, the engine to shut down while driving. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will secure the oxygen sensor wiring by installing an additional fastener to the existing clamp.
