Tiffin Recalls 392 Motorhomes After Manufacturing Screw May Have Punctured Fuel Tank

Tiffin Motorhomes has recalled approximately 392 motorhomes — certain 2025-2026 GT1, 2026 GH2, and 2026 GH1 units — after determining a screw used during manufacturing may have punctured the fuel tank, creating a fuel leak and fire risk, according to the NHTSA recall summary posted the week of June 1, 2026. The recall is filed under NHTSA campaign number 26V338; Tiffin's internal number is TIF-148.

The defect

A puncture in a fuel tank from a manufacturing-stage screw is a classic "right part, wrong place" assembly defect: the fastener belongs in the vehicle, but its installation path intersected the tank. Once a fuel tank is breached, even a slow leak can pool fuel in spaces where ignition sources are present — exhaust components, electrical connections, brake hardware — turning a contained defect into a fire condition.

NHTSA's fuel-system rules treat any unintended fuel leak from the tank as a safety defect because of the ignition risk.

What owners should do

Owners should:

• Check their VIN at nhtsa.gov/recalls under campaign number 26V338 to confirm whether their unit is included
• Park the motorhome outside and away from structures until the remedy is completed, per NHTSA's guidance for this recall
• Look and listen for evidence of fuel leakage — fuel odor, wet spots under the chassis, drop in tank level when parked
• Contact Tiffin or an authorized dealer to schedule the remedy

The remedy is free of charge: dealers will inspect and replace the fuel tank as necessary at no cost. Owner notification letters are expected to be mailed July 24, 2026. Owners can reach Tiffin customer service at 1-256-356-8661 and reference recall TIF-148.

Why this matters for the RV class

Motorhomes — particularly Class A units like Tiffin's GT and GH lines — carry large fuel volumes (often 80-150 gallons of diesel) and are typically operated with families and possessions onboard. A fuel-fire event in a motorhome is consequential in a way it isn't in a passenger sedan; the cabin, the passengers, and the contents are all in the same envelope as the tank.

That is why fuel-tank-puncture recalls in this class draw NHTSA attention even at relatively small unit counts.
