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.

Owner report 11472757 · 2022-07-07 (July 7, 2022)
A recall had been done and thought to be corrected earlier this year, but we just heard a pop as we were pulling into our driveway and I immediately lost power steering and brakes stopped working seconds later. The connection to the Dot 4 tank came undone and all the fluid leaked out. If this had happened while we were driving down the highway I hate to think what could have happened. I am fearful to drive this RV in the future if the recall was fixed and it failed anyway. AAA will be towing the RV to the closest Ford Dealership today for repai…
