Cummins Recalls 2,960 Onan Generators Over Fuel Discharge

Cummins is recalling about 2,960 portable generators because a venting defect can pressurize the gasoline tank until fuel discharges or the fuel cap ejects. The Consumer Product Safety Commission announced the recall on November 12, 2026. It covers the Cummins Onan P5000iDF EFI Dual Fuel Portable Generators, and the commission lists the risk as serious injury from fire and burn hazards.

The defect is mechanical and specific. The valves in the recalled generators were installed incorrectly, so fuel vapors can't vent properly from the gasoline tank. Pressure builds inside the tank instead. That pressure can force fuel out of the unit or pop the fuel cap off without warning, and loose gasoline beside a hot engine is the whole hazard in one sentence.

Cummins has received eleven reports of fuel discharging from the unit and the fuel cap ejecting unexpectedly. One consumer reported being splashed in the face with fuel. The commission says no medical attention was needed in that case, and it reports no other injuries. Eleven incidents across roughly 2,960 units is a high report rate for a product category where most owners run the machine only a few times a year.

The recalled generator is a dark gray dual fuel unit. It runs on gasoline or propane and produces between 4,500 and 5,000 watts depending on the fuel. Cummins is printed in white on the front of the unit, with a handle above the control panel. The Cummins C logo and Onan P5000iDF EFI are printed on the side, and the model and part number sit on a label attached to the side of the generator. Owners should check that label before they assume their unit is clear.

The remedy is a repair, not a refund. The commission tells consumers to stop using the recalled generators immediately and check the model and part number on Cummins' recall page. If the unit is affected, the owner contacts an authorized Cummins service location and arranges a free repair there. Cummins takes questions at 800-286-6467, and its service locator lists the shops that can do the work.

The generators sold from May 2025 through August 2026 for between $1,640 and $1,930. Camping World, Factory Pure, Northern Tool and AP Electric stores sold them, and Cummins sold them online through its own site. That's a recent, expensive fleet: the oldest recalled unit is about eighteen months old, and buyers paid work-generator money, not bargain money, for a machine built for outages, job sites and RV power.

Cummins Inc., of Columbus, Indiana, is the distributor of record. The generators were manufactured in Vietnam. The recall number is 27-087, and the commission classifies it as a Fast Track recall, the program that moves a corrective plan through the agency faster than a standard proceeding.

The timing matters for owners who rely on a generator as backup power. A unit that's recalled for a fuel discharge hazard shouldn't sit fueled in a garage waiting for the next outage. The commission's instruction is to stop using it now and get the repair scheduled, so the machine is fixed before an emergency makes the decision for the owner. A generator that can't run safely during a blackout isn't backup power. It's a liability with a pull cord.
