What's wrong?
The entry door position switch on 2025-2026 Grand Design Lineage motorhomes tells the step system whether the entry door is open or closed. When the switch reads the door as closed, that signal helps keep the powered entry steps stowed for travel. The system depends on steady contact inside the switch.
On affected motorhomes, the switch was installed in a way that leaves the contact intermittent or unreliable. As the vehicle moves, the switch can lose contact and send the wrong door signal. The step controller can misread the door as open, which allows the entry steps to deploy while the motorhome is in motion.
Grand Design says there is little to no warning sign before this happens. The driver does not get a dependable cue that the switch has lost contact, so the steps can move without advance notice.
Who's affected?
The same door-entry assembly is involved for the electrical system and body structure on the 2025 and 2026 Lineage.

What's the safety risk?
The entry steps can extend while the vehicle is moving, which increases the risk of a crash.

Repair will be free at any franchised Grand Design dealer once available.

What happens at the repair
Once Grand Design opens the dealer repair, a Grand Design technician will replace the door position switch so the entry door can be read as closed and the steps do not deploy unexpectedly. The dealer repair will be free once available, with parts and labor covered under the recall. Grand Design uses its standard reimbursement plan for this recall. If you already paid for a related door switch or step deployment repair, keep your repair invoice and payment records so the service desk or Grand Design customer service can review documented expenses.
