Example complaints
Brakes: “Mine is a 5th wheel trailer. It had 7k lb lippert axles from the factory. All four inside seals leaked and got grease on the brake drums and shoes. The trailer brakes didn't work from the first day I got the trailer. I ended up changing out the axles with dexter 8k lb axles with never lube bearings so I would never have this problem again. I found out lippert was reimbursing for this repair. What do I need to do to qualify?”
NHTSA complaint #11067135, filed 2018-02, 6,000 milesSuspension: “One of the passenger side leaf springs on our Dexter axle snapped near the shackle point. Since we have read that this is a common issue, we are reporting as this could have potentially resulted in a serious safety issue. When our leaf spring snapped, it severed the propane line that runs underneath our 5th wheel in two places. It also caused the two tires to rub together. …”
NHTSA complaint #11462558, filed 2022-04Equipment: “I am reporting a potential safety defect involving excessive frame flex and structural failure on a 2018 Grand Design Solitude 384GK fifth-wheel trailer. The RV experienced years of slide-out alignment and operational problems beginning shortly after purchase and Grand Design RV has known about this since then. In September 2023, the bedroom slide unexpectedly extended approximately halfway while the trailer was being towed, creating a significant highway safety hazard. …”
