What's wrong?
The LP gas line on the 2018-2019 Grand Design Solitude is the hose that carries liquid propane to the grill in the optional pull-out outside kitchen. It is supposed to route cleanly as the kitchen moves in and out, then stay secured away from hot surfaces while the grill is operating.
On affected trailers, the line does not have enough attachment points to hold its path. As the outside kitchen is pulled out and retracted, slack in the line can coil under the grill. When that happens, the propane line can touch the underside of the hot grill and sustain heat damage. Grand Design's remedy keeps the existing parts but reroutes the line and adds clamps so the hose stays secured.
Owners can look for visible damage on the outside of the LP gas supply hose. That visible hose damage is the warning sign before the line fails.
Who's affected?
Spans the 2018 and 2019 model years for the Solitude, with the same LPG lines and fittings component listed for each year.

What's the safety risk?
If the LP gas supply hose touches the hot grill, the hose can leak propane and increase the risk of a fire. Check for visible exterior hose damage and avoid using the grill or LP system until a dealer inspects the routing. Repair is free at any franchised Grand Design dealer.
What should I do?
- Check your VIN to confirm your 2018-2019 Grand Design Solitude is included in this recall.
- Contact a franchised Grand Design dealer to schedule the free LP gas-line re-route that keeps the line away from the hot grill.
- Bring the recall notice if Grand Design mailed one. If not, reference recall number 18V399 when you call.
- Avoid using the pull-out outside kitchen or grill until the LP gas line has been re-routed.
What happens at the repair
At the dealer, a Grand Design technician re-routes the LP gas line for the optional pull-out outside kitchen so it no longer contacts the bottom of the grill. The recall repair is free, including parts and labor. If you already paid to have this repair procedure performed, Grand Design RV reimburses all related expenses. Bring receipts or repair paperwork to the service desk, or contact Grand Design RV customer service so they can tell you how to submit the claim.
