From owner reports, verbatim
IOTA ITS 50R TRANSFER SWITCH OVERHEATED AND BURNED SOME ELECTRICAL WIRING. HAS NOT BEEN REPAIRED, SO EXTENT OF DAMAGE IS UNDETERMINED. I CONTACTED IOTA AND THEY SAID IT WAS AN INSTALLATION PROBLEM AND REFERRED ME TO MONACO; MONACO SAID THE COACH WAS BUILT IN A TIME-FRAME THAT WAS NOT PART OF THE RECALL ALTHOUGH THE PROBLEM WITH THE SWITCH WAS IDENTICAL TO THOSE WHICH WERE RECALLED AND REPAIRED, AND THE SAFETY CONCERN THE SAME.
Too few reports in this category for a page of its own — they appear in the full complaint list.
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.
