10V563000 · Equipment:Recreational Vehicle/Trailer
Reported: 2010-11-16 (November 16, 2010)
TMC IS RECALLING CERTAIN MODEL YEAR 2004-2011 DAMON AND FOUR WINDS RECREATIONAL VEHICLES EQUIPPED WITH 1200-SERIES NORCOLD REFRIGERATORS. THE POPULATION OF REFRIGERATORS BEING ADDRESSED CONTAINS EITHER A SENSING ALGORITHM OR THERMAL SWITCH TO SHUT OFF POWER TO THE REFRIGERATOR WHEN HIGH TEMPERATURES ARE DETECTED IN ORDER TO PREVENT A POTENTIAL FIRE. THE RESPONSE TIMES OF THE SENSOR ALGORITHM AND THERMAL SWITCH DEVICES TO STOP POWER ARE NOT SUFFICIENT.
Consequence: 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: TMC 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 NFORMATION. THE RECALL BEGAN ON JANUARY 12, 2011. OWNERS MAY CONTACT NORCOLD AT 1-800-767-9101 OR THOR MOTOR COACH AT 1-877-855-2867.
NHTSA campaign record ↗15V698000 · Electrical System
Reported: 2015-10-23 (October 23, 2015)
Thor Motor Coach (TMC) is recalling certain model year 2009-2011 Four Winds Hurricane and Windsport, 2009-2010 Four Winds Mandalay, 2010 Four Winds Magellan, and 2010-2011 Four Winds Serrano motorhomes manufactured May 2, 2009, to September 1, 2010. The affected vehicles are wired to be powered by a generator and are equipped with an Iota ITS-50R transfer switch that may fail when exposed to elevated electrical loads and used in higher ambient temperatures.
Consequence: As the transfer switch fails, it may overheat, increasing the risk of a fire.
Remedy: TMC will notify owners, and dealers will replace the Iota ITS-50R transfer switch with a transfer switch from another manufacturer, free of charge. The recall began on November 23, 2015. Owners may contact Thor customer service at 1-877-855-2867. Thor's number for this recall is RC000106.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2010: 1 complaints · 2011: 2 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
|---|---|---|---|
| 2010 | 0 | 1 | 1 |

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
