A group of Corvette Z06 owners banded together to launch a class-action lawsuit June 13 alleging the Chevrolet is both unsafe and financially damaging to its owners due to its thermal management issues, reports Automotive News.
GM’s heat-soaking issues with its Z06 Corvette are well-documented, with a Z06 even dropping out of Motor Trend’s 2015 Best Driver’s Car comparison test, defaulting into limp-home mode after a brief time on track.
The 650-horsepower supercharged sports car’s thermal management issues are said to be secondary to an inadequate engine cooling system, which allows the car to build-up excessive temperature before falling into its protective limp-home mode.
Despite the protective decreased-performance limp mode GM built in, heat-soak episodes are said to be responsible for warped vital engine components, leading to expensive repairs.
The 2017 Z06 received an upgraded cooling system, but this year’s model is still listed as an affected car on the class-action lawsuit.
“We believe we’ve found GM to be guilty of a classic bait-and-switch—one that cost thousands of consumers dearly, up to $120,000, and broke state consumer protection laws,” said Steve Berman, managing partner of Hagens-Berman, which filed the suit in the U.S. District Court for the Southern District of Florida.
“GM enticed race enthusiasts with bells and whistles, promising a car that could maintain safe speeds and power when tracked, but we believe what it sold them was far from what it promised. This defect not only damages the Z06 engine, but endangers drivers.”
Attorneys Hagens-Berman estimate more than 30,000 examples of 2015 through 2017 model year Corvette Z06s are affected by this defect, including many sold in Canada, and encourage owners to reach out to the law firm if they own a problematic Z06 of the affected model years.
