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 Feb 16, 2012
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.

Filed Dec 5, 2015
Fire reported

MY MOTOR HOME CAME EQUIPPED WITH THE IOTA ITS-50R TRANSFER SWITCH. IN JULY 2010 IT CAUSED A FIRE IN THE COACH WHICH WAS EXTINGUISHED BY ME AND A NEW TRANSFER SWITCH OF THE SAME MANUFACTURER WAS INSTALLED ON 29 JULY 2010. ON 25 NOV 2015 THE REPLACEMENT TRANSFER SWITCH FAILED (NO FIRE THIS TIME) AND WILL RESULT IN MY HAVING TO REPLACE IT AGAIN, THIS TIME WITH ANOTHER BRAND OF TRANSFER SWITCH. I CALLED MONACO CUSTOMER SERVICE AND COMPLAINED THAT I HAD NOT BEEN NOTIFIED OF THE INITIAL RECALL OF 2012. THEY STATED THAT THEY WOULD ONLY HONOR THE RECALL OF IOTA TRANSFER SWITCHES INSTALLED BY MONACO WHILE THE COMPANY WAS OWNED BY NAVISTAR. MY COACH WAS BUILT BY MONACO COACH CORP. IN LATE 2008. THEY ALSO INDICATED TO ME THAT IOTA HAD DISAVOWED ANY RESPONSIBILITY FOR ANY DAMAGE INCURRED BY THE "DEFECTIVE" TRANSFER SWITCHES. I HAVE DISCONNECTED THE SHORE POWER FOR MY MOTOR HOME AS I DO NOT WANT TO RISK ANOTHER FIRE AND POSSIBLE TOTAL LOSS OF MY COACH AND ITS CONTENTS. THE ONLY WAS I CAN HAVE 110 AC POWER IS TO RUN THE ONBOARD GENERATOR AND I AM RELUCTANT TO DO THAT AS THE POWER STILL GOES THROUGH THE TRANSFER SWITCH. ANY ASSISTANCE THAT CAN BE RENDERED IN REPAIRING THIS DEFECTIVE PRODUCT WILL BE APPRECIATED.
