2025 CHEVROLET CORVETTE

FUEL SYSTEM, GASOLINE

General Motors, LLC (GM) is recalling certain 2023–2026 Chevrolet Corvette vehicles equipped with a left-side radiator/fan combination. Excess fuel may spill into the vehicle fuel-filler pocket during refueling and leak onto an ignition source.

Risk: A fuel leak in the presence of an ignition source, such as hot engine or exhaust components, can increase the risk of a fire.

FORWARD COLLISION AVOIDANCE

The contact owns a 2025 Chevrolet Corvette. The contact stated that while operating the vehicle, the Forward Collision Avoidance alert button was pressed but the Forward Collision Avoidance system failed to activate. The cause of the failure was not yet determined, and the vehicle was not repaired. The local dealer was made aware of the failure. The manufacturer was not yet contacted. The failure mileage was 10.

FUEL/PROPULSION SYSTEM

Please refer to Part 573 Safety Recall Report 25V536. This report seeks to bring to the attention of the NHTSA that additional General Motors, LLC Chevrolet Corvette Models NOT INCLUDED in the Recall Report are virtually identical in design and having the identical safety issue. THE ISSUE: Excess fuel spilled into the fuel filler pocket drains directly into the left-side fan equipped air intake. The air intake is equipped with a thermostatically controlled fan that remains running after engine shutdown if the engine temperature trigger threshold is met. While Safety Recall 25V536 limits the issue to those models equipped with a "radiator/fan combination", to exclude the "fan only" models (Stingray Z51 Equipped in particular) from the recall due to not containing an "ignition source" is short-sighted to state the least in my opinion. Any electric motor is an ignition source as power (typically 12VDC in an automobile) is delivered through "brushes" to an armature that excites the magnetic fields between opposing magnets. The assumption that the addition of a radiator (essentially a sealed cavity have no spark potential) creates an ignition source combination is short-sighted at the least and criminally negligent at best. I am the owner of a 2025 Stingray with a Z51 package. After reviewing 25V536, I conducted a test on my vehicle by pouring water into the fuel filler pocket and monitored where that water went. The test results made it clear to me that to exclude the Stingray is a mistake. Video test results are attached.

STRUCTURE

The contact owns a 2025 Chevrolet Corvette. The contact stated that the rear glass had a one-inch gap, allowing heat to escape the vehicle, and allowing water to enter the engine compartment and inside the vehicle. While the contact was driving at undisclosed speeds in the rain, there was water entering the vehicle. There were no warning lights illuminated. The local dealer was contacted and determined that the issue was not a service issue. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 700.
