A manufacturing defect in thousands of portable generators sold exclusively at Costco could turn the moment you first pour fuel into a deadly inferno—and tens of thousands of Americans might own one right now without knowing it.
Story Snapshot
- Generac recalled approximately 51,500 GP9200E portable generators sold at Costco between May 2025 and February 2026 due to a carburetor defect causing fuel leaks
- The defect poses serious fire, burn, and explosion risks when gasoline is first added, with 114 fuel leak reports but no injuries reported
- Only generators with serial numbers 3016786070 through 3016788388 are affected; units already safely fueled past the “E” mark can continue use
- Consumers can receive free repairs through Generac dealers or full refunds from Costco
- This recall targets a specific serial range sold at Costco, separate from a broader Generac recall covering ten other models sold at Home Depot, Lowe’s, and other retailers
The Hidden Danger in Your Garage
Generac Power Systems issued a voluntary recall in coordination with the U.S. Consumer Product Safety Commission on April 16, 2026, after discovering a carburetor defect that triggers fuel leakage the moment gasoline is first poured into certain GP9200E portable generators.
These orange-and-black steel-framed units, retailing between $600 and $1,300, were purchased by Costco members seeking backup power amid increasingly frequent weather-related outages.
The defect creates an immediate fire hazard during initial fueling, transforming what should be a simple preparation step into a potentially catastrophic event involving flames, burns, or explosions.

Understanding the Scope and Scale
The recall encompasses roughly 51,500 units distributed to consumers through Costco locations across the United States, part of a larger manufacturing run totaling approximately 149,400 generators, including models sold through other retail channels and 260 units in Canada.
Affected generators bear serial numbers ranging from 3016786070 to 3016788388, manufactured and shipped between May 2025 and late February 2026.
Generac received 114 reports of fuel leaks from these units before initiating the recall, yet remarkably, no injuries have been documented.
This stands in contrast to previous generator-related recalls involving carbon monoxide poisoning or fire hazards, underscoring how proactive identification prevented potential tragedy this time.
What Costco Members Must Do Immediately
Generac issued clear directives separating at-risk units from safe ones. Any GP9200E generator within the affected serial range that remains unused or has exhibited fuel leakage must be shut down immediately and not operated under any circumstances.
However, generators already filled beyond the “E” fuel level mark without experiencing leaks can continue operation safely.
This nuanced guidance prevents unnecessary waste while protecting consumers from real danger. Owners should verify their unit’s model number on the side panel and check the serial number against the recall range through Generac’s dedicated recall website or by calling 800-396-9951.
Repair Options and Consumer Rights
Generac established two remedy pathways for affected consumers. First, owners can arrange free carburetor repairs through authorized Generac dealers by contacting the company directly or visiting generac.com/about/recalls/GP-Carburetor.
Second, Costco members retain the right to return affected generators to any Costco location for a full refund, leveraging the retailer’s customer-focused return policies.
This dual-option approach respects consumer preference while ensuring dangerous units exit circulation. The financial exposure for Generac and Costco could reach $30 to $65 million based on the 51,500 affected units at their retail price points, underscoring significant corporate accountability for manufacturing quality-control failures.
Why This Recall Matters Beyond the Numbers
This incident highlights the tension between surging consumer demand for backup power and the manufacturing pressures that can compromise safety.
As severe weather drives up portable generator sales, production volumes increase and quality assurance becomes more challenging.
The carburetor defect slipped through Generac’s manufacturing process, affecting nearly 150,000 units, before consumer reports triggered the investigation.
The CPSC’s involvement underscores federal regulatory oversight functioning as intended, catching hazards before they claim lives. Yet it also raises questions about pre-market testing protocols and whether manufacturers adequately stress-test components under real-world first-use conditions rather than laboratory settings.

The recall reinforces a fundamental principle: convenience cannot supersede safety, and corporate responsibility demands swift action when defects surface.
Generac’s public statements emphasize safety as their top priority, a claim validated by their voluntary coordination with the CPSC rather than waiting for regulatory mandates.
For Costco members, the lesson is simple—verify your equipment immediately, act on recall notices without delay, and recognize that even trusted brands selling through reputable retailers can harbor hidden dangers.
The absence of injuries in this case reflects good fortune and rapid response, not the benign nature of the defect. Fire hazards demand zero tolerance, and consumers holding affected units should treat this recall with the urgency it deserves.
