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, roof failures, and structural deterioration concerns. These reported conditions appear similar to issues currently under investigation by NHTSA under PE24-029, which was opened after complaints alleging excessive frame flex in certain Grand Design fifth-wheel trailers. NHTSA's investigation summary references complaints involving cargo doors opening while traveling, entry doors opening while traveling, and slide-outs extending during transit. The owners report repeated service visits and ongoing failures, yet many of the original concerns allegedly remain unresolved. Of particular concern is the possibility that structural movement, frame flex, body distortion, or a chassis-related condition may be contributing to the recurring slide-out, door, alignment, and leveling-system issues.
