A routine stop at a gas station turned into a fireball for one Corvette owner, and the story didn’t end there. Since this summer, General Motors has launched a recall affecting more than 23,000 ultra-high-performance Chevrolets priced north of $100,000, citing a design flaw that can trigger fires during refueling. The models in question are the Z06 and the forthcoming ZR1, the sharpest blades in the Corvette lineup.
“It happened so fast,” said an owner who watched his 2024 Corvette ignite near the pump. “The car exploded while I was refueling,” he recalled, asking whether anyone else had seen something similar.
A pattern that was hard to ignore
Within about a month, three separate Z06 vehicles reportedly caught fire while owners were adding fuel. On June 10, 2025, an internal GM employee flagged multiple alarming posts, noting uncanny similarities in timing and circumstances. Two days later, a fourth incident hit even closer to home: a development vehicle inside GM’s own fleet.
For a six-figure supercar, this was not an acceptable risk. GM escalated quickly, opening a formal inquiry that would lead to a sweeping recall and a fast-tracked engineering fix.
What the engineers discovered
The culprit wasn’t an exotic engine part but a chain reaction triggered by the cooling hardware on the car’s left side. The fuel filler neck and its pocket sit just above the radiator and its electric fan, a configuration unique to Z06 and ZR1. If gasoline spills into that pocket while the fan is spinning, droplets can be sucked across the radiator, atomized in the engine bay, and exposed to hot surfaces or sparks.
GM’s teams ran targeted tests in late July and mid-August 2025 to replicate the scenario. With the engine off but the fan running, they introduced a small amount of fuel near the filler pocket and observed a rapid ignition sequence matching real-world damage patterns. The conclusion was stark: even a modest spill could escalate into a dangerous flare-up.
Which vehicles are affected
GM’s recall covers 23,656 cars across four model years. Only vehicles with the left-side radiator and fan layout—namely Z06 and ZR1—are included. Stingray and E-Ray models, which use a different cooling architecture, are not affected.
- 5,973 Corvette 2023 Z06 and ZR1 models: early production with the risky layout
- 9,218 Corvette 2024 Z06 and ZR1 models: the most heavily impacted
- 8,160 Corvette 2025 Z06 and ZR1 models: includes pre-sale and press units
- 305 Corvette 2026 Z06 and ZR1 models: very recent builds
For buyers spending well over $100,000, the scope underscores how a narrow design choice can have outsized consequences. While the Z06 and ZR1 pursue track-level cooling, their packaging placed the filler-pocket, radiator, and fan in precarious proximity.
The fix, the timeline, and what owners should do now
GM’s remedy is straightforward yet critical: install a shaped metal shield that diverts any fuel drips away from the radiator and fan area behind the body panel. The repair is free at authorized dealers, with parts and labor covered under the official campaign. Since the recall’s initiation this summer, notifications have been rolling out to owners.
Until the fix is complete, customers are advised not to drive the vehicle and to park it outdoors, away from structures and other cars. Gasoline vapor is unforgiving, and a single spark can escalate into catastrophic damage.
Here are prudent steps while you wait for your appointment:
- Park outside, on a non-flammable surface
- Do not refuel the vehicle under any circumstance
- Contact your dealer to confirm parts availability
- Verify your VIN in the recall database for exact eligibility and next steps
Why this recall matters beyond performance fans
The Z06 and ZR1 are halo products that shape Chevrolet’s reputation far beyond raw speed. Owners expect bulletproof engineering, especially in areas as fundamental as refueling safety. Incidents at the pump carry outsized visibility, potentially affecting resale values, insurance premiums, and brand trust.
The good news is that the defect is specific, reproducible, and addressable with a physical barrier. No engine control magic or software patch needed—just a sturdier boundary between fuel and potential ignition sources. When installed, the shield should neutralize the risk introduced by the left-side cooling layout.
The road ahead for GM and its customers
GM moved quickly once a pattern emerged, condensing investigation, testing, and countermeasures into weeks rather than long months. That urgency reflects the gravity of a fueling fire and the stakes for a flagship nameplate. As the retrofit campaign proceeds, owners should keep meticulous records of all communications and service visits.
“It’ll still be my dream car after the fix,” another owner said, “but I want to know it’s unquestionably safe.” In the end, that is the bar every six-figure supercar must clear—thrilling on the track, uneventful at the pump.
