THOR MOTOR COACH Complaints

The contact owns a 2025 Thor Motor Coach Vegas RV built on a 2025 Ford E-450 chassis. The contact stated that while placing tire covers on the front tires during a trip across the country, the contact noticed that the steel belt around the interior of one of the front tires was visible, and the steel belt was perfectly smooth in the interior of the other front tire. The contact stated that the front tires were worn to the core after driving 600 miles. The RV was taken to Napa Auto Care, where the front tires were replaced. Additionally, the mechanic informed the contact that the tires failure was due to the clamps and tie rod end on the right side of the steering wheel being loosened, causing damages to the front alignment. The mechanic tightened the clamps, and the RV was repaired. The Ford manufacturer was notified of the failure and referred the contact to a Ford dealer to fill out a form for reimbursement. The dealer later informed the contact that the manufacturer had denied reimbursement because the chassis was sold to the Thor Motor Coach manufacturer. The Thor Motor Coach manufacturer was contacted and informed the contact that the Ford manufacturer was responsible of the Chassis warranty coverage. No further assistance was provided. The failure mileage was approximately 4,837.

We purchased this brand new Thor, Axis from Lazydays, Tampa in January of 2022. We have only used it once since taking delivery (the slide was broken at that time). It has been in and out of the shop for months at a time for over 3 years, for various items, including the "brain" (3 times), the outside jacks, the slider, cracked windshield (while in service), severe water intrusion etc. The fact that this has been going on for so long and the response from Thor has been, "our only responsibility is to insure that you get service". No one wants this much service, expecially on something brand new. My husband is a Retired, 100% Disabled, Army Veteran and I can't tell you how this has stressed him. This is our 6th Camper and we have never had such a nightmare. Can you assist. We got it out of the shop yesterday....

The vehicle I rented — a Thor RV based on a Ford E350 — was handed over with a missing lug nut on one wheel and a dangerously loose lug nut on the opposite rear wheel. The component that failed is part of the wheel fastener system (lugs/nuts/bolts). It is not available for inspection now, as the vehicle has since been returned to the rental company. This situation posed a serious safety risk — had the remaining nuts failed while driving, the wheel could have detached entirely, potentially leading to a crash or injury. I noticed the issue during a basic inspection many miles after the pickup. I was forced to buy and install a replacement lug nut myself to make the vehicle roadworthy and safe to drive. I have the propf that the vehicule was handed over to me with a missing lug nut as the video I took during tje check in shows the missing lug nut. The issue was confirmed independently by me, and I informed the rental company immediately. They acknowledged the problem and promised to refund the cost of the part. However, it has now been over two months, and they have neither issued the refund nor provided any follow-up. The vehicle was not inspected by police, manufacturer, or insurance, as I managed to resolve the issue myself to avoid driving in unsafe conditions. There were no warning lights or messages — only a physical inspection revealed the problem. I am filing this report because I believe the company rented out a mechanically unsafe vehicle, and others could be at risk if this is not addressed.

The contact owns a 2024 Thor Freedom Traveler Motorhome built on a 2022 Ford Motorhome Chassis. The contact stated that the propane tank was overheating. There were no warning lights illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 24V426000 (Equipment). The RV was taken to the local dealer but was not diagnosed or repaired. The manufacturer was contacted and confirmed that the RV was not under recall. The failure mileage was approximately 920.

The drivers seat is 3-6 inches to the right of the steering wheel causing hard steering/handling at times (curves). No accidents involved. Our first long drive with this vehicle. The issue does not sound like a big deal but the drivability is definitely a problem. In my opinion.

The Thor motorhome has several windows. The windows they installed are laminated windows, with two panes of glass and a seal or glue which connects the outer glass to the inner glass. The attachment method for the outer glass is ineffective. As a result, the outer glass pane comes loose from the inner and is prone to fall off or fly off at highway speeds. The risk is that the pane could strike another vehicle and possibly cause an accident. Already Thor has replaced two of the window units on this unit around 2021, not under warranty but as a customer courtesy. I now have a third window unit that is experiencing the same problem. It is apparent to me Thor has acknowledged there is a risk present when they replaced the other units. In addition, Thor has issued a recall for several year models after my year model. It seems clear they are aware there is a risk of window failure in model years outside of the recall. Unfortunately, they are unwilling to address the risk and hazard.

The contact owns a 2023 Thor Motor Coach Miramar. The contact stated that while the vehicle was parked, the entry door latch failed to unlatch. The contact was stuck inside the RV and could not unlatch the door. In addition, the contact made several attempts to unlatch the entry door and the entry door handle fractured and detached. The contact stated that a good Samaritan arrived and assisted the contact with exiting the RV. The RV was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 8,176. The VIN was not available.

The 8000 lb hitch failed disconnecting towed car. It happened when entering the highway. If this happened at speed it could have been catastrophic. There have been numerous failures of this hitch.

Drove from Gibson Louisiana to Abita Springs Ocean Canyon RV park. Upon arrival we had a buzzer alert going off under dash, we then parked to RV. Tried to put jacks down, did not respond, tried 12v lights did not work, tried slides, again no response. We then plugged in and were able to get jacks and slides out, some lights worked. Still alarm under dash, checked 12 coach battery, almost dead. Called a mobile RV tech, 2 1/2 hours later, he found a ground bolt had come off with 3 grounding wires on it. Tech advised that bolt was only tacked on one side, my Warranty company said a original technician fault and not covered. Talked to Thor later, they advised that is how it is attached, advised warranty company and they still denied. Told Thor that was very poor workmanship for a company trying to improve their standing. This cost me $358.05 out of pocket and time from Rving.
