What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2014 Thor Motor Coach Ace, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

BOUGHT RV FALL 2017. WHILE PARKED IN GARAGE, COULDNT GET IN BECAUSE DOOR LOCKED BY ITSELF. HAD TO BREAK INTO RV AND TAKE DOOR HANDLE OFF AS KEYS WOULD NOT OPEN IT OR MANUAL OPERATION WOULD NOT OPEN IT. REFUSED TO PURCHASE ANOTHER REPLACEMENT FOR FEAR OF THIS HAPPENING AGAIN.

TL* THE CONTACT OWNS A 2014 THOR ACE. WHILE DRIVING VARIOUS SPEEDS IN THE RAIN, THE WINDSHIELD WIPERS FAILED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE RELAY BOX FILLED UP WITH WATER. THE VEHICLE'S RELAYS WERE REPLACED AND THE POSITION OF THE BOX WAS MOVED TO PREVENT WATER INTRUSION. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 17,000.
