What's wrong?
The driver and passenger seat bases on 2025-2026 Grand Design Lineage recreational vehicles are the metal mounting structures that fasten each front seat to the floor pan. They keep the seat fixed in position so the seat, seat belt geometry, and occupant position stay controlled during normal driving and a crash. The critical fasteners at the base need to be tightened to the vehicle manufacturer's specified torque, which means a measured amount of clamping force.
On affected Lineage RVs, the seat bases were not properly torqued during assembly because production did not follow the vehicle manufacturer's specification. A loose or under-tightened base can shift against the floor pan instead of staying locked down. That is why the recalled RVs do not meet the federal seating-system requirement.
The warning sign is movement at the seat base where it connects to the floor pan. If the driver or passenger seat rocks, shifts, or feels loose at the base, treat that as the warning sign.

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 seat base can let the seat shift during a crash, increasing the risk of injury. If the seat moves at the base where it connects to the floor pan, have it inspected and tightened. 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 seat-base inspection and tightening that secures the driver and passenger seats.
- Bring the recall notice if Grand Design has mailed one. If not, reference recall number 26V277 when you call.
- Avoid using any seat that shifts or feels loose until the dealer confirms the seat base is properly tightened.
What happens at the repair
At the dealer, a Grand Design technician inspects the driver and passenger seat bases and tightens any seat base fasteners that were not secured correctly. The inspection, tightening, and labor are free under the recall. Grand Design used its general reimbursement plan on file for this campaign, so owners who already paid for seat base repair work should bring repair paperwork and payment documentation to the service desk or contact Grand Design customer service to start a claim.
