What's wrong?
The ThermaHeat tank pad on the 2026 Grand Design Lineage is an electric heating pad mounted at the water tank. Its job is to warm the tank area during cold weather so plumbing contents do not freeze. It works by sending electrical current through the pad, which creates controlled heat at the tank surface.
On affected recreational vehicles, electrical terminals inside the pad were not attached correctly. That poor connection creates high electrical resistance, so current does not move through the pad as designed and the pad can fail. Grand Design identified the issue on units built with the substituted ThermaHeat part, rather than the other brand pad used outside this recall.
There is no warning sign before failure. The owner is not expected to hear, smell, or feel a change before the tank pad stops working. If the pad fails, the first sign can be that the tank heater no longer performs as expected in freezing conditions.

What should I do?

- Do not drive the recreational vehicle until Grand Design gives repair or movement instructions.
- Arrange a tow if the recreational vehicle has to be moved to a dealer; do not drive it there yourself.
- Contact Grand Design customer service at 1-574-825-9679 with questions and reference recall number 26V057 when you call.
- Ask a franchised Grand Design dealer about the free heating-pad inspection and replacement that addresses the fire risk from a failed water tank heating pad.
What happens at the repair
Grand Design's final dealer repair is still under development, so do not treat this as ready for a service appointment until Grand Design opens the repair. Once available, a Grand Design technician will inspect the ThermaHeat tank heating pads and replace any heating pad that fails inspection. The dealer repair will be free, with parts and labor covered under the recall. Grand Design used its general reimbursement plan for this campaign, so documented out-of-pocket repairs tied to this defect are handled through that plan. Bring prior repair paperwork to the service desk and ask how to submit it.
