THOR MOTOR COACH Complaints

The contact owns a 2022 Ford E-450. The contact stated that while operating the vehicle, the parking brake light remained illuminated, causing the ABS to become inoperable. Also, the message "Service Advance Trak" was sometimes displayed disabling the ABS and the cruise control. The cause of the failure was not determined. The local dealer and manufacturer were notified of the failure. The failure mileage was 3,000.

My front cap has been leaking for about a year, and I have had it "repaired" three times already under warranty. It is still leaking, and, in fact, it may be getting worse. This cap contains, among other things, a nearly queen-sized bed for sleeping. I have read on Thor forums that countless other owners are having similar problems, which stems from the front cap not being secured/installed correctly. This includes missing seals and/or missing screws. My fear is that this cap will continue to sag/loosen and eventually fall/break off while I am driving, or while someone is sleeping in this area. This potentially could result in fatalities / loss of human life.

Windshield wipers get stuck in the up position. Going highway speed in heavy rain. Lost visibility. Spoke with Larry Long with NHTSA. He advised that I make this report and that there are active recalls for this problem.

There is a recall for my vehicle it is notice # 2021070007 despite your website stating there is none. My problem with your recall is that it only applies to the rear wheel sensors on the Mercedes sprinter chassis. I've had both front and rear wheel sensor failures on my sprinter both failures coming with less 5000 miles on my sprinter which the Mercedes dealership refused to repair. I don't why NHTSA would limit the recall to just the rear sensors when the front sensors are exactly the same as the rear sensors and are failing also. These are dangerous failures which disable the safety systems on the vehicles.

The contact owns a 2022 Thor Motor Coach Scope built on a 2021 Ram Promaster 1500 chassis. The contact stated that while driving at various speeds, an abnormal grinding noise would emit from the vehicle. The contact had taken the RV to several independent mechanics who informed her that the generator was improperly installed on the trailer. The generator had been installed below the axle and should have been installed above the axle. The contact was informed that the generator was a major safety hazard that could cause a potential failure. The manufacturer was notified of the failure and stated that she would receive a call back. The contact had not received a call back from the manufacturer. The vehicle was not repaired. The failure mileage was approximately 2,200.

The contact owns a Thor Motor Coach Challenger. The contact stated while the RV was parked and covered in the driveway, the contact entered the RV and became aware that the inside of the RV was severely burned. The contact stated that the fire was contained inside of the RV. There was no visible fire damage on the outside of the RV. The contact stated that the fuse panel was completely burned. The insurance company hired a forensic company to inspect the RV however, a thorough inspection was not yet completed. A police report was filed. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure and was awaiting a response. The failure mileage was approximately 6,000.

After driving from California to New York, I saw that screws holding the Front Cap (cab over bunk) had started to back out and delaminated the trim. If the screws continue to back out, it is possible that the entire front cap attached to the Ford Chassis could break apart from the RV and injure the passengers or people on the road. I have reported this issue to Thor and I am awaiting feedback if they are able to repair. There are also many other Thor Magnitude customers reporting this issue online.

2015 THOR, SK35 Super C Motorhome. Front cap over cab of chassis has defective hardware holding the front nose cap to the rear section of the main coach box. Screws are to small and break after just a few thousand miles. When the cap separates it causes vibrations and leaks to the Ford F 550 chassis.

The cabover cap that attaches to the main RV body is coming loose and appears to be separating from the body.

Whenever I drive the vehicle, I get a 'Service Advance Trac' error message and the cruise control / stability control system stops working, and the vehicle gets difficult to drive. This occurs in regulat conditions at highway speeds. It appears to be a very common problem that Ford has not addressed. I have not been to the dealer yet because the nearest Ford Truck center is over 100 miles away and appointments are 3 months out.
