The contact owns a 2018 Thor Motor Coach Four Winds Motorhome constructed on a 2017 Ford E-350 Chassis and hauling a 17-foot cargo trailer. The contact stated that while traveling to another state in the mountains, the RV suddenly began to buck and lost motive power and stalled on several occasions. The contact was able to pull over safely. There were no warning lights illuminated. The RV was taken to an independent mechanic who determined that the fuel module needed to be replaced. The RV was repaired, but the failure reoccurred. A mobile RV mechanic determined that the fuel module needed to be replaced. The RV was repaired, but the failure persisted. The RV stalled, leaving the occupants stranded for several hours, but eventually restarted. The RV was taken to the local dealer, where it was determined that the OEM fuel module needed to be replaced but eventually used an aftermarket fuel module. The RV was towed to another local dealer, Harry Robinson Sallisaw Ford (2300 S Kerr Blvd, Sallisaw, OK 74955) where it was determined that the fuel module, fuel pump, and PCM needed to be replaced. The vehicle was repaired, but the failure persisted, and the RV was towed back to the same local dealer. The manufacturer was contacted, who confirmed there was no warranty coverage on the RV for the failure. The failure mileage was approximately 70,000.
