2022 Grand Design Solitude

On January 18, 2026, while towing my 2022 Grand Design Solitude 310GK near Bouse, Arizona, I discovered a serious problem and pulled off the road. The rear axle had become detached/displaced. At the time, I did not know exactly what had occurred or what caused the axle event. The RV was subsequently delivered to a repair facility on March 27, 2026. During the repair process, significant structural/frame damage was progressively discovered, including cracking in the spring-hanger/frame area. The repair facility documented that the damage was more extensive than initially believed and performed structural repairs that included additional steel and plating. My insurance company approved $23,615.83 in total repair costs, with a net repair cost of $23,365.83 after the $250 deductible; not all of that amount was frame-related. During this process, Grand Design referred me to Lippert regarding frame repair information. I subsequently received a Lippert frame repair procedure addressing inspection and repair of frame cracking. Grand Design has advised that my RV is not within the date range of the related program. I have asked Grand Design and Lippert to review the documented structural repairs and determine whether they are consistent with Lippert's frame repair procedure and whether the RV is structurally safe for highway use. I have specifically stated that I am not asking them to determine the cause of the January incident or certify the repair facility's workmanship. I am seeking a competent engineering determination concerning the structural/frame condition and repairs. I am reporting this to NHTSA because failure or cracking of the frame/suspension attachment structure on a large towable RV could create a serious highway safety risk. The cause of the January axle event and when the frame cracking developed are UNKNOWN. The cracking was discovered progressively during subsequent repairs.

I own a 2022 Grand Design Solitude 346FLS fifth wheel trailer. The trailer has been at the dealership for over nine months after structural frame cracks and weld separations were discovered during inspection. The cracks appear in structural frame components and welded areas supporting the chassis. This raises concerns about the integrity of the trailer frame during towing and braking. In addition to the frame defects, all four leaf springs in the suspension system have failed or lost structural integrity. This suspension failure presents a safety risk because it affects axle alignment, load support, and trailer stability while towing. The trailer manufacturer (Grand Design) and dealer have been notified, but the unit has remained out of service for an extended period while the manufacturer decides how to address the problem. Structural frame cracking combined with suspension failure represents a serious safety concern for a towable RV traveling at highway speeds. I am submitting this complaint so the issue can be investigated for potential defects affecting other trailers of this model or similar models.

The contact owns a 2022 Grand Design Solitude RV. The contact stated that while driving 65 MPH and hauling the RV, the rear passenger's side tire of the RV experienced a blowout. The contact was able to pull over to the side of the road. The contact replaced the tire with a regular-size spare tire; however, the rear passenger's side tire experienced a second blowout while driving on the same day. The contact stated that the tire failures caused damage to the RV. The vehicle was taken to the dealer, where it was diagnosed with frame flex, frame steel fracture, and missing screws around the hitch, and unparalleled axles. The RV was not repaired. The manufacturer was notified of the failure, and a Grand Design technician confirmed that the RV was experiencing excessive frame flex, which the contact related to the tire failure. The manufacturer recommended towing the RV to one of their locations for frame repairs, but the contact was advised that the repair of the axle damage caused by the tire failures, prior to towing the vehicle, would be paid for out-of-pocket. The RV was not repaired. The failure mileage was approximately 20,000.

The contact owns a 2022 Grand Design Solitude. The contact stated while driving at an undisclosed speed, the doors unlatched and opened. The contact stated that the bolts were missing, the furniture moved, and the walls shifted. While driving at an undisclosed speed, the RV failed to drive in a straight line. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed with fractured slides and failure to the frame. There was an unknown diagnosis related to the suspension. The vehicle was repaired to the original specifications, but the failure recurred. The manufacturer was not contacted. The failure mileage was unknown.

The contact owns a 2022 Grand Design Solitude. The contact stated that while pulling into a campground she was informed to check the tires. The RV was taken to a tire center where it was discovered that the brakes had crumbled and there was a spring inside. Additionally, the equalizer was cracked. The contact stated that while driving 75 MPH on the highway, a wheel on the RV detached. The RV was taken to an independent mechanic who determined that the axle was cracked. The local dealer was contacted several times. The RV was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 10,080.

My unit has had multiple frame failures. this is where the frame is literally breaking due to being under engineered by the manufacturer. There are many things that happen due to this. walls don't line up floors squeak, doors wont close. But the worst problem of all is the danger of towing. With a broken frame many things can happen including loss of life. This is what I fear the most. I have had this repaired once already by the factory and it is doing the same things again. I feel unsafe in and towing my unit.

We have had multiple failures of the slides, the tsb that was supposed to fix the sagging problem in the kitchen has now also failed. Presently one of kitchen slides won’t extend. We have excessive frame flex. Recently Grand Design inspected the hitch area and re-welded 3 areas that had cracked and broken welds. Added the larger lag bolts per their service bulletin. They were unable to check the upper deck at the time due to not have the necessary tools to do that. The front cap has separated from the roof slightly. The rear wall has now started to separate from the side walls. We also have a broken part in the suspension. The interior walls have cracked by the kitchen slides. Grand Design has been notified complete with photos. I am awaiting their response. These issues began very early after purchase and have only gotten worse with time.

Frame failure at the pin box, 2 cracked welds, missing lag screws on upper decking rails and wrong size, had dealer inspect and make repairs per Grand Design, these defects are putting me and my family, and other people on our highways at risk due to possibility of complete king pin failure and rv coming detached from tow vehicle, I personally feel that Grand Design and Lippert are covering up a severe defect on these frames and poor construction quality at the expense of the consumer, which has drastically decreased the value of my rv which I now feel is defective and just waiting for a serious accident every time I hitch it up to my vehicle. The way I was aware of issue was from other Solitude owners who were having same issues. I feel there should be a recall or buy back of these defective rv's to remove them from our highways before a fatality occurs.

We are experiencing signs of excessive frame flex like many others with similar Lippert frames. We have a squeaky floor in the front and rear. We have furniture rubbing in the front and pulling away from the wall. The stairs inside the door are rubbing as well. The rig makes excessive creaking noises while being towed. We have an appointment to take it to the Grand Design service center in June. Until that time, we will not be towing anywhere. We are frankly a little concerned about the 600 mile trip.
