The sensing algorithm or thermal switch installed to shut off power to the refrigerator when high temperatures are detected due to a possible hydrogen gas leak may not shut off in sufficient time to prevent a fire.

Remedy

Winnebago is working with norcold to identify and notify any affected owners. Owners will be instructed to contact norcold dealers to receive the remedy free of charge. Please see norcold's defect report 10e-049 for additional information. The recall began during december 2010. Owners may contact norcold at 1‑800‑767‑9101 or winnebago at 1‑641‑585‑3535.

What is wrong

Certain motor home chassis equipped with zf model 8018 steering gears may have been assembled with the incorrect recirculating ball spacer. This could potentially allow the recirculation balls to escape from the recirculation ball circuit resulting in a loss of steering.

Risk

The operator may notice higher required steering wheel inputs,or the need for more steering wheel adjustments, while driving in a straight line in combination with metallic cracking noises prior to a loss of steering. Loss of steering could result in a vehicle crash.

Remedy

Winnebago is working with freightliner and zf to replace the steering gear free of charge. Owners may contact winnebago at 641‑585‑3535 or freightliner at 1‑800‑547‑0712.

What is wrong

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.

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.

Remedy

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.

Recall number 05V573000 · Recall details

During this investigation, ODI identified 29 reports of cracked and/or fractured hitch receiver assemblies installed on the subject vehicles.The majority (27 of 29) of the reported hitch incidents occurred prior to the initiation of PE10-048 in December, 2010.This investigation has been characterized by (1) Scant forensic samples available for inspection and review since most of the reported incidents occurred prior to ODI?s investigation and pertinent material has been scrapped; (2) Uncertainty regarding the contributory role of issues such as unintended hitch contact with road surfaces, use of hitches with offsets that exceed Winnebago recommendations; and (3) Other usage factors.Based on reported failures, the indicated failure rate for detected and reported cracking /fracture incidents associated with the estimated population of subject vehicles was found to be 0.10% after the vehicles had been in service for between 6 and 8 years.Reports were higher in calendar year 2007 (9 reports) than in succeeding years 2008-2010 (3-5 reports per year) and 2011 (2 reports) and appear likely to decline further due to diminished use associated with vehicle aging.ODI is aware of only one consumer complaint (ODI# 10368002) in its files describing a hitch receiver malfunction in Winnebago-Itasca vehicles.As of September 2013, Winnebago has reported that there have been no additional incidents of cracked or fractured hitch receivers reported since the most recent incident reported in May 2011.A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist.The agency will take further action if warranted by the circumstances.For more detailed information, see the attached closing report.
