THOR MOTOR COACH Complaints

The contact owns a 2004 Thor Hurricane built on a 2003 Ford F-550 chassis. The contact stated that while driving 45 MPH, the vehicle stalled with the check engine warning light illuminated. The brake pedal was applied but failed to respond and the steering wheel seized. The contact stated that several unknown warning lights flickered and lost power. The vehicle was able to restart and drive to the residence. The vehicle was not diagnosed or repaired. The VIN was not included in NHTSA Campaign Number: 13V265000 (Electrical System). The manufacturer was notified of the failure. The failure mileage was 39,000.

On several occasions, I have received a "High Tire Pressure" warning indicating that one of my tires is either too hot or the pressure is excessive. On other occasions, I have gotten a High Tire Temperature Warning. Daimler Truck North America issued a campaign on this (number SF644A-C) and I took my motorhome in to get repaired. They reprogramed the TPMS computer. However, I am still having problems. I have contacted the dealer, they tell me they do not know of any other repairs or campaigns for this issue and there is nothing that can be done at the moment. This issue is extremely nerve-racking when the alert comes up on my dash while I am on the highway. I am in constant fear that one of time tires will blow out if i ignore the warning, but again there is nothing I can do. I would like them to examine this issue and replace all the sensors/computers if needed. Thank you. 22V-379 JPH 6.7.22

floor of storage area is failing this could cause items in storage to fall out while driving. the items that fall out could be hit by the tires of the motorhome or hit another vehicle causing a serious accident.

The emergency brake system is connected to the leveling stabilizers and the slide out system with this coach. The brake must be manually engaged for those systems to be used. To deploy the levelers and slides and to retract both . The brake handle will not function sometimes . It will not be recognized by those systems . The brake will also not clear itself from those systems and will stay on when not needed. The same issue was brought to the attention of a repair facility of a General RV dealership in Ashland Virginia. It was from another owner of a 2022 Thor unit similar to my vehicle. The problem could not be duplicated by the service team and the owner did not receive a repair to my knowledge. I am concerned that this is a issue that should be addressed. I also have several sections of wiring inside the coach and under the coach that are not protected in looms that is standard in vehicle assembly. I also have found nuts and bolts that are not tight at all. Those are connected to a metal bar under two coach seats that have safety belts to use while the coach is moving. The safety belt system is connected to that steel bar. What guidelines are in place that protects the owners from poor assembly practices of Recreational Vehicles ? And how do I report those violations to the agency that enforces those safety codes ? There are several areas if concern with the assembly with this coach. Where does the responsibility lay ? When two manufacturers are involved. Mercedes Benz and Thor Motors . I do have pictures and a repair invoice to substantiate my claim. And will be glad to send those to you by email. Thank you , hope to hear from you very soon.

FRONT PASSENGER SIDE AIRBAG, CHRONIC WARNING LIGHTS, MULTIPLE REPAIR ATTEMPTS BY 1st and 2nd OWNER

THE FRESH WATER TANK, WHICH WAS ONLY HALF FULL OF WATER, BROKE THROUGH THE FLOOR ALLOWING THE TANK TO DROP DOWN TO THE ROAD. I WAS PULLING INTO A GAS STATION TO FILL UP WITH FUEL. LUCKILY IT HAPPENED BEFORE I GOT ON THE INTERSTATE AND WOULD HAVE BEEN TRAVELING AT A HIGHER RATE OF SPEED. THE TANK IS LOCATED IN FRONT OF THE REAR DUAL TIRES ON THE PASENGER SIDE OF THE MOTORHOME. AT A HIGHER SPEED, IF THE TANK DRAGGING ON THE GROUND WOULD HAVE COME LOOSE I WOULD HAVE RUN OVER THE TANK WHICH PROBABLY WOULD HAVE CAUSED LOOSING CONTROL OR EVEN FLIPPING THE MOTORHOME OVER ON ITS SIDE. THE FLOOR APPEARS TO BE A 1/8” MASONITE PANEL HELD UP BY SCREWS THAT IS USED TO SUPPORT 100 GALLONS OF WATER when full. That is 830 lbs. of water plus the tank weight. THERE IS NO METAL SUPPORT GOING ACROSS THE CENTER OF THE TANK underneath so the entire tank is held by the Masonite and screws. THOR CUSTOMER SERVICE TOLD US IT IS OUT OF WARRANTY AND NOT THEIR PROBLEM. EXTENDED WARRANTY SAID IT IS A FACTORY DEFECT AND NOT THEIR PROBLEM. THE CUSTOMER SERVICE AT THOR WOULD NOT LET US TALK TO A SUPERVISOR . I HAD ALREADY NEGOTIATED A DEAL ON A NEW ONE BUT HAD NOT SIGNED PAPERS YET. THE DEALER ESTIMATE WAS $10,000 DOLLARS of which I HAD TO PAY $5,000 TO KEEP THE DEAL. DEALER INDICATED TO ME THAT EIGHT OTHER UNITS OF THIS MODEL HAS HAD THE SAME THING HAPPEN. THE FLOOR IS DROPPING DOWN AT SEVERAL OTHER PARTS OF THE BASEMENT FLOOR. THIS APPEARED WITHIN SIX MONTHS AFTER PURCHASING THE ARIA. THE THOR MOTORHOME SHOULD BE AVAILABLE AT THE DEALER WHERE IT WAS TRADED. I HAD TO USE A BINDING RATCHET strap TO HOLD THE FLOOR AND THE TANK UP OFF THE GROUND WITH THE TANK EMPTY.

The contact owns a 2019 Thor Windsport Motorhome built on a 2018 Ford F53 Chassis. The contact received notification of NHTSA Campaign Number: 20V804000 (Equipment). The contact took the vehicle to a dealer where the vehicle was serviced under recall. The contact stated that a year later, the contact stated while driving 30 MPH, the cabinet that was repaired under the recall fell down onto the dashboard while driving. The contact's wife had to manually lift part of the cabinet in order for the contact to resume normal driving. Once the contact reached his destination, he inspected the RV and saw that the cabinet was secured by self-tapping screws which was an inadequate repair for the cabinet. The contact purchased his own materials and was able to make minor repairs in order to safely drive home. The dealer was notified of the failure and informed him that the recall was already satisfied and that no other assistance could be offered. The contact also spoke with the manufacturer and filed a complaint. The RV was not repaired. The failure mileage was unknown. Consumer had their Motorhome since serviced and found a new problem , that resulted during that same time as the cabinet failure as consumer was driving. On that same trip consumer had a fire happen in the battery compartment of the motorhome. The shop that repaired the cabinet said the fire was a result of a battery cable coming from the engine battery to the motorhome battery compartment had fallen onto the drive shaft of the motorhome resulting in complete wear to the wiring and causing the wiring to short out causing tremendous heat to the wiring causing the fire.

Hello We took the RV on our trip in Nov 2021 and noticed cold air entering the cabin near the driver and passenger feet. After pulling the 45degress trim that covers sits between the floor and wall I noticed that is a gap and I could see the road. Upon further investigation it looks like the side wall has separated from the floor of RV. Upon further research, it appears the entire length of the sidewalls of the RV is attached to the floor using 3&1/2 inch machine screws. In my case those screws had sheared off. That essentially means the side walls on both sides are coming off loose from the bottom. I am shocked that THOR would make such a shoddy design. The gaps between the floor and side wall exposes the entire coach to outside air and makes passengers venerable to exhaust fumes from the generator, especially when travelling at highway speeds as there is considerable low pressure in side the cabin. I am afraid the whole structure of the RV above the floor is at risk of a catastrophic failure. This is a 26000 LB Class RV and the way side walls are attached to the floor and to the chassis with these flimsy screws that are simply drilled into the L-bracket of the floor does not seem like a design that can withstand the stresses put on it. Thor has refused to fix this issue. I urge you to kindly investigate this issue as it probably affects all there Class A RVs. Please reach out to me at [XXX] or [XXX]. I have pictures and videos of the issue but not right now. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Rear Sway Bar Bracket manufactured from weak cast iron. Known problem and FORD will do nothing to fix it except to replace with same faulty part.

Screws that hold the rv body together at the corners are breaking off and /or backing out. If all these screws come out which they are known to the body could fall apart going down the highway. I’ve read forums where everyone that has submitted complaints are experiencing this problem on all Thor Motorcoach models, Omni and Magnitude. Thor is totally aware of this problem. The only way to tell this problem exists is to visually inspect the moldings that cover these screws and the molding will bulge out. bolt JPH
