What is wrong

Grand Design RV, LLC (Grand Design) is recalling certain 2026-2027 Lineage recreational vehicles equipped with certain MaxxAir N-Series Maxxfan rooftop ventilation fans. The printed circuit board may fail during certain operations and overheat.

The risk

An overheated printed circuit board increases the risk of a fire.

Why electrical defects matter: Electrical faults can cause a loss of power, disable safety features or, where wiring overheats, start a fire.

The remedy

Dealers will inspect and replace the printed circuit board as necessary, free of charge. Owner notification letters were mailed July 21, 2026. Owners may contact Grand Design customer service at 1-574-825-9679. Grand Design's number for this recall is M910063.

About the electrical system

Modern vehicles run on dozens of control modules and miles of wiring; an electrical fault can affect lighting, displays, power or safety systems.

What to do

  1. Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
  2. Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-446 and the manufacturer’s number M910063.
  3. If you notice burning smells, flickering power or warning lamps, have the vehicle checked before continuing to use it.
  4. Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.

Check by VIN

A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.

Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.

Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
