On March 13, 2026, just 8 days after purchasing a new 2026 Thor Rize motor coach built on a RAM ProMaster 1500 chassis, the driver-side rear wheel completely detached from the vehicle while traveling approximately 60 mph on Interstate 15 in California. I observed sparks in my rearview mirror and immediately pulled over due to fear of fire, especially given the presence of a propane system. This was a sudden and dangerous failure with no warning. The vehicle was towed and I was later informed that a critical component in the wheel/rotor assembly had failed. The vehicle was undrivable and required transfer to a RAM dealership with no clear repair timeline. Due to the severity of the safety issue and inability to safely continue travel, I was forced to trade in the vehicle at a significant financial loss and purchase a replacement vehicle. A complete wheel separation on a new vehicle at highway speed presents a serious safety hazard and could have resulted in severe injury or death.

Reading this record
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
