Fire risk prompts recall of Corvette Z06 and ZR1 models

Corvette Z06 and ZR1 recalled

On August 22, 2025, Chevrolet recalled 2023–2025 Corvette Z06 and 2025–2026 ZR1 models. During refueling, spilled fuel near the filler can be drawn by the left-side radiator/fan toward hot components, increasing fire risk.

GM confirmed the issue and said it was rare. A stop-sale was applied to all Z06 and ZR1 dealer inventory. GM planned to fix the problem by adding a shield to keep fuel from heat sources. NHTSA has posted the filings and will track repair completion.

Number of Corvettes affected by recall

The recall covered about 25,500 Corvettes. GM produced 16,052 Z06 cars in 2023–2024 and around 9,234 Z06 and ZR1 units in 2025–2026. Only a few hundred ZR1 cars were made by mid-2025.

Other Corvette models were omitted. The left-side radiator assembly was specific to Z06 and ZR1. The ZR1X was excluded because it had not yet been produced. GM focused the recall on vehicles with the exact fuel-spill risk described in the documents.

NHTSA role in Corvette safety recalls

The National Highway Traffic Safety Administration reviewed all Corvette Z06 and ZR1 recall documents in 2025. They confirmed the fuel-spillage risk and ensured GM’s recall procedures followed federal safety rules.

NHTSA also published official notices online for owners and dealers. The agency tracked completion of repairs and verified that shields were installed correctly. Their oversight helped prevent accidents, ensured compliance with safety regulations, and provided public records for each affected vehicle.

ZR1 debuted in Miami in July 2024

The 2025 Corvette ZR1 made its debut in Miami in July 2025. It had a twin-turbo 5.5L V8 LT7 engine with 1,064 horsepower and 828 pound-feet of torque. This was the most powerful V8 ever made by an American auto company.

ZR1 production was limited by parts and supply, not by design. GM said component availability would define production numbers. Buyers expecting a ZR1 needed patience because supply could affect delivery. Exact production figures were not announced.

Price expectations for 2025 ZR1

Chevy had not shared official pricing by July 2025. Readers guessed the starting price would be $175,000 to $200,000. The 2024 Z06 started at $111,000 for base trim and $125,000 for top trim.

The ZR1 offered more power than the Z06. Its 5.5L LT7 engine outperformed the Z06’s 5.5L LT6, which produced 670 horsepower. The ZR1 could reach 215 mph and cover a quarter mile in about 10 seconds. Buyers expected high performance at a higher price.

ZR1 exhaust adds thrust to car

Former engineer Tadge Juechter said in July 2025 that the ZR1’s exhaust air moved close to the speed of sound. The exhaust even added some thrust to the car, helping performance.

The LT7 twin-turbo V8 had four central exhaust tips. Quarter-mile times were under 10 seconds, and top speed was around 215 mph. Juechter retired after the ZR1’s debut, ending nearly 50 years of work on American sports cars.

C8 Corvette uses GM Y2 platform

All 2023–2025 Corvette C8 models, including Z06 and ZR1, rode on the GM Y2 platform. Production happened at the Bowling Green, Kentucky, plant. The platform supported speed, handling, and performance safety requirements.

The LT7 engine was a flat-plane crank DOHC design, based on the Z06’s LT6. GM designed the car for high-speed performance while meeting road safety rules. Bowling Green handled assembly, quality checks, and final inspections.

Theories about parked ZR1

People guessed the C6 ZR1 owner might be overseas, in jail, or deceased. The garage was attached to an office building, suggesting the owner worked there. No official reason was shared for the car being parked.

The Corvette still looked intact. Owners or heirs were expected to retrieve it. Reddit users discussed the theories while noting the rarity and value of the ZR1, showing why people cared about its storage and condition.

2020 stop-sale for brake issue

In September 2020, GM stopped selling 2020 Corvette C8 cars due to a brake-by-wire sensor problem. The issue affected other models, including the 2020–2021 Buick GX, 2020 Cadillac CT4, CT5, XT4, and 2021 Trailblazer.

Contaminated materials during production could break communication between the sensor and the brake boost system. Warning lights appeared on instrument panels. Owners were advised to wait for replacement parts and take vehicles to dealers once fixes were available.

Brake problem could affect stopping

The brake issue required extra pedal force, increasing the chance of accidents. GM reported the problem to NHTSA under recall code A202307260.

Dealers would replace the electronic brake boost module when parts arrived. Stop-sale applied to new and used vehicles. This action ensured safety while GM prepared the permanent repair.

2014 SUV fire risk recall

In August 2014, NHTSA updated a recall for five GM SUVs, including Chevrolet Trailblazer, Buick Rainier, GMC Envoy, and Isuzu Ascender. The driver’s door window control module could short-circuit and cause a fire, even when the car was off.

Owners were told to park outside until repairs are made. Earlier fixes in 2012 and later modifications did not fully solve the problem. Dealerships would inspect circuit boards and replace modules to prevent fire risk.

Affected SUV models and years

The 2014 recall included 2005–2007 Saab 9-7X, 2006–2007 Trailblazer, Envoy, Rainier, and 2006 Trailblazer EXT and Envoy XL. The master power switch could corrode from fluid entry, creating a fire risk.

GM notified owners and provided customer service numbers. Replacement parts were not immediately available, but letters informed owners of updates. Dealerships ensured that older modifications were replaced with fully functional parts.

GM repair plans for recalled SUVs

Dealerships inspected the master power switch module in each SUV. Vehicles with earlier modifications got full replacements. GM focused on safety while parts were being produced.

Owners could call brand-specific customer service for guidance. The recall reduced short-circuit and fire risks. GM ensured that power window systems worked properly and that owners received timely fixes.

ZR1 and Z06 production challenges

During 2023–2025, Corvette Z06 and ZR1 production faced delays due to limited parts and supply chain issues. GM had to adjust schedules at the Bowling Green plant to meet demand.

Special components like aero packs and carbon fiber parts caused bottlenecks. GM brought in additional suppliers to maintain production. These adjustments ensured the vehicles met performance standards while addressing safety and quality requirements for each model.

The new ZR1X set a record with a standout performance at the Nürburgring. See details in Chevrolet ZR1X celebrates new Nürburgring achievement.
