What is wrong

Tiffin Motorhomes, Inc. (Tiffin) is recalling certain 2025-2026 GT1, 2026 GH2, and GH1 motorhomes. A screw may have punctured the fuel tank during manufacturing, causing a fuel leak.

The risk

A fuel leak in the presence of an ignition source, increases the risk of a fire.

Why fuel system defects matter: A fuel leak near an ignition source increases the risk of fire, and a failing fuel pump can stall the engine while driving.

The remedy

Owners are advised to park outside and away from structures until the remedy is completed. Dealers will inspect and replace the fuel tank as necessary, free of charge. Owner notification letters were mailed June 23, 2026. Owners may contact Tiffin customer service at 1-256-356-8661. Tiffin's number for this recall is TIF-148.

What to do

  1. The manufacturer has advised parking these vehicles outside and away from buildings until the remedy is done, because of the fire risk.
  2. Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
  3. Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-338 and the manufacturer’s number TIF-148.
  4. If you smell fuel or see a leak, do not drive the vehicle — park it outside, away from buildings, and call the dealer.
  5. 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.
