What's wrong?
The solar panel on a 2025-2026 Grand Design Lineage is mounted on the roof and helps feed electrical power into the RV's solar charging system. It is supposed to stay bonded to the roof while the vehicle moves, flexes, and sees wind load on the road. The adhesive backing is the part doing that holding work.
On affected Lineage RVs, the adhesive bond securing the panel to the roof was not strong enough. Grand Design traced the problem to inadequate adhesion or inadequate pressure during bonding, which lets the panel loosen from the roof surface. Once that bond starts to release, normal travel can finish separating the panel until it detaches.
Owners can look and listen for the warning sign before failure. A solar panel that is lifting, loose, rattling, or visibly separated from the roof needs dealer attention before more travel.
Who's affected?
Both model years list the same solar-panel adhesive part and the same electric propulsion system fastener component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
A loose or detached solar panel can fall from the RV and become a road hazard for other vehicles, increasing the risk of a crash. If you see the panel lifting or hear it moving, schedule the repair soon and drive cautiously until it is secured. Repair is free at any franchised Grand Design dealer.
What should I do?
- Check your VIN to confirm your 2025-2026 Grand Design Lineage is included in this recall.
- Contact a franchised Grand Design dealer to schedule the free solar-panel securing repair, which fixes the adhesive problem that lets a roof panel detach.
- Bring the owner letter if you have it, and reference recall number 26V042 and Grand Design recall M910053 when you call.
- Inspect the roof solar panels before travel and stop using the RV on public roads if any panel looks loose, lifted, or damaged.
- Call Grand Design customer service at 1-574-825-9679 with questions about scheduling or dealer handling.
What happens at the repair
At the dealer, a Grand Design dealer technician checks the roof mounted solar panels and properly secures them so the adhesive failure does not let a panel detach. The recall repair is free, and parts and labor are covered. Grand Design used its general reimbursement plan on file for this campaign. If you've paid out of pocket for this solar panel repair before the recall notice, ask Grand Design customer service or the dealer service desk how to submit documented expenses.

What should I do if my 2025-2026 Grand Design Lineage is on this recall?
