General Motors (GM) has announced a serious safety defect that may affect certain 2023–2026 Chevrolet Corvette vehicles. The issue is linked to models equipped with a left-side radiator and fan combination, which are found in Corvette Z06 and ZR1 models.
According to GM, excess fuel spilled into the fuel-filler pocket during refueling could leak onto hot radiator surfaces and potentially ignite. This dangerous condition raises the risk of a vehicle fire, even while the car is turned off.
What Is the Chevrolet Corvette Fire Risk Defect?
In the affected vehicles, the fuel-filler pipe and recessed pocket sit directly above the left-side radiator and cooling fan. If a refueling spill occurs—especially if a gas pump fails to shut off properly—the spilled fuel may leak onto the radiator.
When the fan is running, it can draw spilled fuel through the radiator, vaporize it into the engine compartment, and expose it to ignition sources. If ignited, this can result in a sudden vehicle fire.
GM’s investigation confirmed that at least four Corvette fire incidents were connected to this defect, two of which involved malfunctioning gas station pumps that failed to shut off properly.
Timeline of GM’s Safety Investigation
- June 10, 2025 – GM received a report through its “Speak Up for Safety” system after a social media post claimed three Corvettes caught fire during fueling within 30 days.
- June 12, 2025 – A GM-owned Corvette test vehicle caught fire while refueling.
- June 17, 2025 – GM officially opened a product investigation.
- June 20, 2025 – Engineers identified distinct burn patterns on the left-side radiator of the test vehicle.
- July–August 2025 – Controlled fuel-spill simulations showed that fuel leaks in vehicles with a left-side radiator could ignite under specific conditions, replicating the burn damage seen in real-world fires. Vehicles without this radiator design did not ignite.
- August 14, 2025 – GM’s Safety Field Action Decision Authority (SFADA) decided to launch a safety recall.
Models Affected by the Safety Recall
While the issue involves Corvettes from model years 2023 through 2026, GM confirmed the left-side radiator/fan combination is only used in:
- Chevrolet Corvette Z06 (2023–2026)
- Chevrolet Corvette ZR1 (2023–2026)
All confirmed fire incidents involved Corvettes equipped with this radiator design.
Risks to Drivers and Passengers
If fuel leaks during refueling and reaches an ignition source, the risks include:
- Vehicle fire while stationary
- Potential injuries or fatalities (two incidents reported minor injuries)
- Damage to property and fueling stations
GM’s Recommended Precautions for Corvette Owners
Until repairs are completed, Corvette owners should take the following precautions:
- Always ensure the fuel nozzle is fully inserted into the filler pipe.
- Do not overfill the gas tank; stop after the pump clicks off once.
- Always turn off the engine before refueling.
- Be cautious at gas stations with malfunctioning or leaking pumps.
The Official Fix
GM has announced that dealers will:
- Install a protective shield to divert spilled fuel away from hot components.
- Begin mailing owner notification letters on October 6, 2025.
- Send a second letter once permanent parts and remedies are available.
The National Highway Traffic Safety Administration (NHTSA) has assigned this defect campaign number 25V-536.
Can Lemon Law Help Corvette Owners?
If your 2023–2026 Chevrolet Corvette has experienced repeated problems, you may have rights under the California Lemon Law and other state lemon laws.
The law may entitle you to:
- A repurchase (buyback) of your Corvette
- A replacement vehicle
- Or cash compensation if your car qualifies as a lemon
Since the defect involves a serious safety risk, owners should act quickly. Consulting with an experienced Lemon Law attorney can help determine if your Corvette qualifies for relief. If repeated safety issues, downtime, or repair delays affect your Corvette, you may qualify for protection under Lemon Law.
