Tiffin Recalls Its Motorhome Lineup Over a Circuit Board Fire Risk

Tiffin Motorhomes is recalling 425 vehicles spanning nearly its entire 2026 and 2027 luxury and expedition lineup after finding that a rooftop ventilation fan’s circuit board can overheat badly enough to become a fire risk while parked or on the road.

The recall, filed with NHTSA under campaign number 26V412, covers the Allegro Bay, Allegro Breeze, Allegro Bus, Allegro Open Road, Allegro RED, Byway, Midas, Open Trail, Phaeton, Wayfarer, Zephyr and GT1 model lines, touching nearly every recreational vehicle Tiffin currently builds.

What Is Actually Failing

The defect sits inside certain MaxxAir N-Series Maxxfan rooftop ventilation fans installed across the affected coaches. NHTSA’s filing describes a printed circuit board that can fail in operation and overheat. The board carries live current even in a partial failure state, so an overheated board can act as an active ignition source, giving a minor electrical fault the potential to start a fire inside the coach’s roof structure.

Rooftop vent fans run almost continuously in many motorhomes, most of all on warm-weather travel days and while parked at a campground with the generator or shore power engaged to keep the interior cool. That near-constant duty cycle is part of what makes a circuit board defect in this specific component more concerning than a fault in a rarely used system. The fan simply spends more hours energized than most other onboard electronics.

The Free Repair

Tiffin dealers will replace the defective circuit board free of charge for every affected coach. Owner notification letters are scheduled to go out on August 28, 2026. Owners do not need to wait for the letter to arrive before scheduling service, and can contact Tiffin customer service directly at 1-256-356-8661 to confirm whether their coach is included and to book an appointment.

Owners can also confirm recall status independently by entering their coach’s 17-digit Vehicle Identification Number at NHTSA.gov/recalls. The VIN is typically printed on the vehicle’s registration paperwork and on a manufacturer’s plate near the driver’s door or dashboard.

Part of a Larger Wave of RV Recalls

Tiffin’s fan recall arrived alongside two other RV safety filings from Jayco covering separate defects. One covers 2024 Jayco Alante and Entegra Vision motorhomes over missing or incorrect cargo capacity labels, information drivers rely on to avoid overloading axles and tires. The other affects 2027 Entegra Accolade and Jayco Seneca models, where front dinette structural wall brackets were left out entirely on the factory assembly line, a defect that can weaken the coach’s interior structure in a crash.

Together, the three RV recalls filed in the same week reflect how much manufacturing complexity has grown inside modern motorhomes. A single coach now integrates household-grade electrical systems, climate control, structural cabinetry and a full chassis drivetrain, and a defect in any one of those systems can trigger a federal recall regardless of whether the vehicle’s engine or brakes are involved at all.

Why RV Recalls Are Different From Car Recalls

Motorhome recalls move through a smaller service network than mass-market car recalls. Tiffin sells and services its coaches through a limited number of authorized dealers concentrated in fewer states than a brand like Ford or Toyota, which can mean longer wait times for parts and scheduling once a recall notice goes out. That delay tends to be worst in the peak summer travel months, when RV service bays are already busy with routine maintenance.

Owners planning a summer trip in an affected coach should call ahead rather than waiting for a routine service visit to raise the recall. Some dealers can perform the fix on a same-day basis if the replacement board is in stock, while others will need to order the part first, information worth confirming before showing up unannounced.

Interim Safety Steps Before the Repair

Until the circuit board is replaced, Tiffin and fire safety experts recommend a few precautions consistent with general RV fire safety practice. Owners should avoid running the affected vent fan unattended for extended periods, keep a working smoke detector active near the roof vent location, and make sure a charged fire extinguisher remains accessible inside the coach at all times, a standard recommendation for any motorhome regardless of recall status.

Owners who notice unusual heat, an electrical smell, or discoloration around the vent fan housing should stop using the fan immediately and contact Tiffin or an authorized dealer rather than waiting for the scheduled repair window. These are the same warning signs fire investigators look for in any circuit-board-related ignition case, and catching them early is the most effective way to avoid an incident before the permanent fix is installed.

Insurance carriers that write RV policies generally treat an open, unrepaired safety recall the same way they treat any known defect: coverage for a fire loss tied directly to a manufacturer defect under an active recall can be complicated if the owner had reasonable opportunity to get the free repair completed and did not. Owners should keep a copy of the recall notice, the date service was scheduled, and any correspondence with Tiffin or the dealer. That paper trail can matter if a claim is ever filed before the repair is finished.

Why RV Fires Are Especially Dangerous

A fire that starts in a motorhome’s roof structure spreads differently than one in a house or a passenger car. The roof cavity of a coach like the ones covered under this recall typically contains foam insulation, wiring runs for multiple electrical circuits, and the ductwork for the air conditioning system, all packed into a confined space with limited airflow to slow combustion. Once a fire reaches that cavity, occupants often have far less warning time than they would in a home fire, and the coach’s living space sits directly below the ignition point.

The National Fire Protection Association has long flagged electrical failures as one of the leading causes of RV fires, alongside propane system leaks and engine compartment fires. A circuit board defect that can overheat while the vehicle is parked, rather than only while driving, adds a specific risk: occupants could be asleep or away from the coach entirely when the failure begins, reducing the window to notice smoke or unusual heat before the fire grows.

Checking a Coach Before You Buy

Buyers shopping the used RV market this year should build recall verification into the same inspection routine they already use for mileage, tire wear and water damage. Tiffin’s dealer network is smaller than a mainstream automaker’s, so recall repairs on used coaches can lag longer after a sale than they would on a used sedan. That gap makes it worth asking for a copy of the service record showing the circuit board replacement rather than taking a seller’s word that the work was done.

What Owners Should Do Now

Owners of a 2026 or 2027 Tiffin coach in one of the affected model lines should take three steps: confirm their VIN is included in campaign 26V412 at NHTSA.gov/recalls, call Tiffin customer service or an authorized dealer to schedule the free circuit board replacement, and monitor the vent fan for warning signs in the meantime. All repairs tied to the recall are free of charge under federal law regardless of the coach’s warranty status.

Anyone shopping for a used Tiffin motorhome built in the 2026 or 2027 model years should ask the seller directly whether the vent fan recall repair has already been completed. An open recall remains attached to the vehicle regardless of how many times it changes hands, and a buyer who skips that question could inherit a repair the previous owner never scheduled.
