Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Jun 25, 2010
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

I HAVE A 2008 MONACO DIPLOMAT MOTORHOME WHICH HAS A ITS-50R TRANSFER SWITCH MANUFACTURED BY IOTA ENGINEERING, TUCSON, AZ. TWO RV MANUFACTURES, NAVISTAR AND KEYSTONE, HAVE DONE VOLUNTARY RECALLS UNDER CAMPAIGN NUMBERS 12V060000 AND 11V577000. MY UNIT IS NOT ON THE RECALL BECAUSE NAVISTAR PURCHASED MONACO CORPORATION UNDER CHAPTER 7 AND ASSUMED NO LIABILITY FOR MOTORHOMES BUILD UNDER THE MONACO CORPORATION NAME. THE NHTSA NEEDS TO START AN INVESTIGATION ON THIS TRANSFER SWITCH. IT HAS BEEN REPORTED BY NUMEROUS TRAILER TRAILER, FIFTH WHEEL, AND MOTORHOMES OWNERS THAT THESE UNITS HAVE GOTTEN HOT TO THE POINT OF BURNING WIRES AND CAUSING FIRES. ACCORDING TO SOURCES SOME OF THE INTERNAL PARTS OF SOME UNITS MAY HAVE BEEN MADE FROM INFERIOR MATERIALS WHICH OVER TIME DEGRADE AND INCREASE RISK OF OVER HEAT. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
