THOR MOTOR COACH Complaints

Since purchase in April 2022, driver seat has side to side and up/down movement which is not part of the design, and appears to be unstable and potential safety hazard for driving. This movement does not occur in the similar swivel style passenger seat. Dealership stated seat issues would be repaired under warranty from Thor. Multiple repair attempts were made by authorized service provider (dealership) addressing other seat issues (not adjusting or rotating properly as designed), but excessive play in the seat still exists. Continued requests have been made to have this addressed in a timely fashion. Dealership and manufacturer have been questioned on whether there is potential safety risk for seat to come loose or dislodged during a collision due to this unstable movement, with no answers. Have seen multiple posts online that other Thor Class B owners are experiencing similar issue. LCI/Lippert (the original seat manufacturer) has been contacted and deferred us back to Thor, as they have agreement with Thor for ongoing service of these parts.

This is a Class A Motorhome. It has one door for entering and exiting the camper. The door handle to get in and out is a horrible design. As a firefighter it scares me and I plan to change it as soon as I find a perfect match. If you are outside trying to get in you can not open the door easily. You have to pull it with 2 hands and violently force, yank, pull the door open. This is definitely a safety concern. This specific type of door handle is a well known issue with Thor motor homes. There has been so many complaints and concerns about it but currently there is no perfect match to replace it. How can Thor be aware of this and still continue to make this handle.

A wiring harness was found pinched, pins bent and broken, apparently in the process of mating the motorhome body to the cassis cab. This cable has power in it and could result in a vehicle fire. Thor has been completely unresponsive in assisting me, despite acknowledging it’s out of warranty, and I simply needed verification of their integration to the chassis, to reassure the after market warranty that this wasn’t something “tampered with”. As a retired fire fighter, I have seen the result of RV fires. They burn fast, and people die. I felt I had no option but to refer this after their intransigent and dismissive attitude. I can supply additional documentation when I retrieve the vehicle from the shop.

The contact owns a 2021 Thor Motor Coach Freedom Traveler built on a 2020 Ford F-59 chassis. The contact stated while driving 60-65 MPH, the leveling system warning light illuminated. Smoke then filled the cabin of the RV due to the hydraulic line rubbing against the exhaust system. Additionally, hydraulic fluid was leaking from the RV. The contact pulled over and exited the RV. The contact waited until the smoke had cleared and the hydraulic fluid had drained, then drove to the residence. The RV was then towed to the dealer, where it was determined that the hydraulic line needed to be replaced and rerouted. The RV was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 12,000.

The contact owns a 2015 Thor Challenger RV built on a 2014 Ford F-53 chassis. The contact stated while driving approximately 60 MPH, he observed from the passenger side rear view mirror that the door skin had begun to peel away from the door. The contact pulled off the roadway and observed that the skin had delaminated from the door and had only been held in place by the lock and door handle. The contact took the door handle and lock mechanism off and removed the laminate and stored it in the RV. The contact had not taken the vehicle to a local dealer. The RV was not diagnosed or repaired. The contact had attempted to contact the manufacturer and left a voice message requesting a call back. The contact researched online and related the failure to NHTSA Campaign Number: 21V845000 (Structure) however, the RV’s VIN was not included. The failure mileage was approximately 53,000.

After the gas powered fridge was turned on. Approximately an hour later the back side of the unit was in flames causing extensive damage and totaling the RV. The failure of the equipment caused the fire. This problem has been ongoing with similar models and is well documented. Has been investigated by a Fire Inspector.

The contact owns a 2023 Thor Motor Coach Vegas. The contact stated that while driving at 60 MPH, the awning unintentionally deployed. Additionally, an unknown part from the awning had detached. The RV was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 3,000. The VIN was not available.

The solar panel mounted by Thor on top of the van detached and flew off while I was driving on the highway and encountered cross wind. From what was left on the solar panel bracket, it looks like there were cracks in the metal around where the bolts were attached for a long time. The solar panel brackets were very loose and floppy allowing the panel to move while the vehicle was in motion or under high wind.

Fuel line to generator is long rubber hose rubbing on screws. Same with electrical wires. Exhaust from generator and vehicle coming back in from exposed holes in floor under cabinetry. I have informed THOR motor coach. This vehicle is unsafe and could catch fire due to rubber fuel line leaking onto exposed electrical connections or exhaust. Holes in floor for tubes and electrical are not sealed allowing fumes to come in. Couch that has seatbelts attached, metal is cut into two parts allowing seat belts to pull on separate metal bars that would break loose. Metal bar should be solid across, cut out is hidden by couch. Wires behind cabinetry floats around, nothing to hold them from flopping around eventually causing shorts. With as many unsafe issues, it would appear no one has inspected these changes THOR has made to the Dodge Promaster.

The roof/ window leaks creating rot in floor and wall operation. Has been to manufacture as well as dealer to many times. 10 plus times.
