I am submitting this complaint regarding recurring safety-related defects involving a 2022 Grand Design Solitude 3950BH. According to the owners, numerous defects began shortly after delivery in 2023 and have continued despite repeated repair attempts. The most significant safety concerns involve: Multiple slide-outs reportedly opening during transport. Persistent "Excess Twist Detected" warnings from the leveling system. Structural alignment issues, including cabinet, trim, shelving, and interior component separation. Repeated slide-out malfunctions, including crooked operation, binding, and floor damage. Cargo-door and latch-related concerns requiring multiple repairs. Water intrusion,…

The center hanger was bent inwards along with the lower plate of the frame being tilted inward. This bowed out the vertical frame web and left the shackle tilted at an angle. The RV was taken to a dealer and they sent info to Grand Design for warranty approval. 53 days after the dealer inspected our rig, Grand Design finally told us they were denying warranty coverage due to this same dealer repairing the frame at the front nose (but not doing anything around the suspension area). I was told by Grand Design and the RV dealer (after I had moved the rig about 125 miles) that I shouldn't move the rig without it being repaired. I did have my insurance inspect it, but they wouldn't cover it as…

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…

Documented Symptoms consistent with the conditions described in Grand Design TSB 24-001 1. Dynamic Sidewall Separation â Driver and Passenger Sides The upper-deck sidewall area displays visible movement under load. When the trailer is connected to the truck via the pin box, the exterior trim and sidewall gap noticeably widens. When the trailer is leveled on its landing gear, the separation compresses and partially closes. Additional observations include: â¢Separation of exterior trim components â¢Cracked and widening caulk joints â¢Visible movement beneath both upper-deck slide-out openings These conditions were first observed following an approximately 300-mile round trip completed on…

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…

While performing a factory recall on the RV, the mobile RV tech discovered underlying issues. He suggested that we get an in-depth evaluation. I contacted and dropped the RV at the shop for diagnosis. The shop discovered extensive frame damage (weld break) at the main beam connecting the pin box and also total frame break and separation on the upper deck floor support. There is substantial floor sagging above the outriggers extending from the living area through the back of the RV. The whole rear of the RV is sagging, causing wall cracking and slideout damage. The shop also measured a considerable deflection (pin box to front bottom frame) while performing the manufacturer's instructions…
