What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
First incident occurred when driving in a heavy rain storm, the passenger side wiper arm disappeared from the windshield and eventually became entagled with the drivers side rendering the wipers from working. Went to the dealer and was told they would be unable to look at it.
I have had several wiper failures on my motorhome that thor has not been able to correct. The first happened in january 2015 when driving down the road at 55mph during a normal rain, the drivers side wiper arm over extended causing the wipers to be out of alignment.
We had an issue with the outside kitchen on our 2015 mirimar. On our last outing, one of the struts that hold the door open broke off. Nobody was hurt, but it was scary. I took a look at the strut and it looked fine. However, the bracket on the door was badly bent.
Found rear sway bar bracket upper bolt missing, bracket loose and bushing out of place. No modifications have been made to sway bar, axle or chassis. This condition was found while preparing the vehicle for winter storage. It was not noticed during any inspection during the summer.
