NHTSA Complaint #11532559 — 2022 GRAND DESIGN SOLITUDE

I just had my rv at the dealership in December of 2022 for repairs and maintenance on the rv including the suspension system. Within 300 miles the shackle bolt broke twisting the spring and then shearing off the wheel/rim/tire sending it flying down the highway. The rotor dragged on the roadway until I could stop resulting in damage to the rotor and brake line. I have a five year warranty on the suspension, however Grand design and Dexter axle refused the warranty blaming me for non maintenance and or overtorquing the shackle bolts. With a Facebook page dedicated to grand design solitudes like mine I have heard of numerous situations like mine with suspension issues. I believe there are issues with this rv bring over weight for the axle systems/suspensions being used. This heavy of an rv should be a tri axle at the least. Grand design picks and chooses who they assist and who they don’t. I think even offering a 7k dual axle system is way underrated. Please help fix this unsafe situation.
