What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There are several things starting off with frame flexing issue causing numerous of parts to fail and move out of place. The manufacturer did a repair of this and my confidence in it being repaired correctly is very low. I do not feel safe towing this RV anywhere. Second, the broken leaf spring on the front axle.
There were no warning lights illuminated. The local dealer was not contacted. The RV was not diagnosed or repaired. The manufacturer was contacted. The failure mileage was unknown.
Trailer Brake failureâThe rear trailer brake wires were discovered to be severed inside the wheel drum from the factory. For the first year of use they were inoperable. This was suspected and confirmed with a thermal camera. The tow vehicle also alarmed âCheck trailer brakesâ while driving.
A spring snapped in two near the mounting point to the frame. Rv was not overloaded. Grand design authorized replacement of all springs which is now complete. Others have had similar failures. Im guessing the metal used was too brittle.
The plastic screen door cover was missing and was unable to be found. A few miles later I noticed the front underbelly storage area on the passenger side was swinging open. Some power tools fell out and were unable to be found. A few hundred miles later the propane door unlatched and was swinging open.
Frame flex issue outside spec dealer said they fixed it but it comes back.
