What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2023 Thor Motor Coach Rize, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
NHTSA has previously issued a recall on the failed LP hose on Rise/Scope vehicles 21V-755. For some reason, my vehicle/VIN was not included in the recall. Nevertheless, I experienced the identical failure described in the recall, but I take exception to the recall pointing to the tight bend in the hose being the issue. My hose is literally disintegrating for the full length of the hose. It appears that the rubber is defective. My vehicle had about 7500 miles on it and hadn't been driven in bad weather when I experienced the leak. Photos are attached. I think NHTSA should revisit this recall and ensure that it is expanded to include all vehicles that might have this part, plus not blame the issue on the hose bend. I kept the hose and can send it for evaluation if needed. For the record, my hose leaked catastrophically when I switched on the gas, and if an ignition source was nearby, a fire certainly could have resulted from this failure.
The generator sits 5 inches from the ground below the rear axle. It is not protected with any encasement, bump stops or axle shims. Please see Bulletin TSB-21-06 for using parts kit #0503506. I have contacted the dealer and manufacturer about this and the say that there was no recall on my vin# for this. They have not offered to do anything about my concerns. The dealer inspected before I purchased the vehicle on 10/21/2003. My concern is the generator will hit a bump and tear off and hit the driver behind me.

This unit is a 2024 Thor Rize class B RV on a 2023 Ram Promaster chassis. The FCW frequently and regularly turns off and will not reset. The FCW light illuminates and appears to affect other random electrical systems that also illuminate. I can manually reset it in the safety settings sometimes but regardless, it shuts off at will. This event is constant in all road, weather and driving conditions. This is a severe safety issue that appears to have been a Ram problem for years now. This is unacceptable and needs immediate and urgent intervention. In the event of an accident, whereas, this system is malfunctioning, I will immediately seek legal actions.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
