NHTSA Complaint #11419770 — 2021 GRAND DESIGN REFLECTION

The electric brakes on our brand new 2021 Grand Design Reflection 303RLS periodically go out. We get a warning through the brake controller that the trailer is disconnected or to "check trailer brake wiring." The warning will go away and the electric brakes will work again, only to have the problem return with the complete loss of trailer brakes. This problem occurred on our very first outing with the new 5th wheel trailer. We have contacted Grand Design customer service through telephone and email, but have received no response. We have scheduled a service appointment to have this issue investigated, but the service department at General RV in Huntley, IL has pushed out our appointment several weeks as they are quite busy. Having no brakes on a 5th wheel trailer that weighs close to 12,000 lbs. loaded is obviously quite concerning to us.
