The aux alternator installed to charge the house battery is failing, making noise and almost starting the motorhome on fire. A quick search found EVERYONE with the Thor motorhomes with this alternator is having the same issues and Thor will do nothing about it. Many have installed multiple new alternators, and because the wiring gauge isn't big enough (also installed by Thor) the issues come up again, and again. Many people have been left stranded, many have had to put a fire out due to this defect. I contacted Thor and they are well aware of t…

The grey water tank empty valve hangs close to the road without support. Mine fell off somewhere while driving cross country. This has happened to many owners and I believe it poses a highway safety hazard.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
