Chevrolet Finally Fixes Corvette Z06 Overheating Issue

Sports Cars / Comments

And a handy warranty extension to go with it.

The C8 Corvette is now into its second year of production, but it hasn't been without its teething issues. Of course, this is all part and parcel of releasing a performance car to the market, and Chevrolet has had its fair share of issues with such cars in the past. But if there's one thing you don't want from a performance car, particularly if it's called the Corvette Z06, is for it to start overheating when you're thrashing around your local racetrack. Back in 2017, that's what happened for owners of the C7 Z06, the track-focused 650-horsepower sports car. Despite GM upgrading the cooling systems, the performance cars still overheated, prompting a class-action lawsuit. Now, a further three years later, General Motors is finally fixing the issue with some new components and an extended warranty.

This is according to GM Authority, which cites a document issued to its dealer network indicating that a warranty extension had been effected on 2015-2018 model year Z06s. The wording in the notice states that the cars "may have a condition where the vehicle may overheat and enter a reduced power mode when driven on a track at sustained high speeds in high ambient temperatures."

The extension of the warranty applies to issues arising from this specific circumstance and is applicable for 7 years/72,000 miles from "the date the vehicle was original placed in service, regardless of ownership."

But Chevy also wants to prevent the issue from causing further trouble, and dealers have been instructed to fit an updated radiator package and updated gearbox calibration for automatic-equipped derivatives. Naturally, these are no-cost repairs to the customer, but the repairs will only be made if a customer can provide proof of the issue by means of a diagnostic code, photos, or video. Hopefully, these upgrades will prove better than the previous GM-authorised improvements that included revised hood vents and a reworked cooling system, which still resulted in several reports of overheating.
