Grand Design service campaign 26-008
Grand Design filed this with NHTSA as a service campaign dated Aug 11, 2026, received Jun 26, 2026, about the electrical system — 2 documents under this number. It names 1 model year (2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThis bulletin describes the procedure to install the Compressor Power Relay Upgrade on affected Lineage units. The upgrade routes the A/C compressor positive power feed through a dedicated 120-amp relay, removing the compressor load from the control board. The upgrade is supplied as SDG kit 5000041 (GDRV PN 710676). GDRV has updated the scope and instructions on this campaign.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.
Model years it names

None of these model years has a page on this site (it covers EPA-certified cars, trucks and SUVs from 2016), so the bulletin is listed here on its own.
Common questions
Source: NHTSA, 49 CFR 579.5Is Grand Design 26-008 a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls.
Is the 26-008 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 26-008 cover?
The manufacturer filed it against 1 model year: 2026 Grand Design Lineage. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
