What's wrong?
The air conditioning unit in a 2017-2018 Grand Design Imagine trailer needs secure wiring connections to carry power without exposed or loose conductors. At the unit, bell cap wire connectors hold wire strands together so the circuit stays complete while the trailer moves and vibrates during travel.
On affected Imagine trailers, those bell cap connectors were installed improperly. A wire can detach from the connector, leaving loose wiring near the air conditioning unit. When loose wires touch the wrong contact or surface, they can create a direct short in the ceiling area. That short can overheat wiring and start a fire near the air conditioning unit.
The warning sign is that the air conditioning system stops operating. Treat that as a serious clue, because the failed connection is in the same wiring that feeds the unit.

What happens at the repair
At the dealer, a Grand Design technician replaces the existing air conditioning wire connectors with positive retention wire connectors so the AC wiring stays secured at the unit. The recall repair is free, with parts and labor covered. If you already paid out of pocket for AC wiring repairs tied to this defect, Grand Design says those expenses are reimbursable. Bring your repair invoice, payment record, and any related AC wiring paperwork to the service desk or contact Grand Design customer service to start the reimbursement claim.
