Chevrolet Corvette Z06 owners have filed a fourth class action against General Motors relating to a cooling defect with the high-performance supercar.

The class action, filed by law firms Hagens Berman, Grossman Roth Yaffa Cohen, the Miller Law Firm, and Schuler Halvorsen Weisser Zoller Overbeck, claims that Chevrolet knowingly sold Z06 models with a cooling system defect that renders them stuck at low, unsafe speeds after about 15 minutes of track driving.

The lawsuit asserts that there are up to 30,000 Corvette Z06 models from the 2015, 2016, and 2017 model years which could be affected. This latest suit includes new cases from owners in Colorado, Connecticut, Georgia, Kansas, Michigan, Missouri, Nevada, Ohio, Pennsylvania, South Carolina, and Texas. It also adds implied warranty claims to the list of complaints against GM.

“Instead of building a car that could live up to the hype it created, GM chose to pour its resources into an onslaught of deceptive marketing, touting to would-be buyers that the Corvette Z06 had ‘track-proven structure and technologies,” managing partner of Hagens Berman, Steve Berman, said.

“What Z06 owners received from GM – a car that peters out after 15 minutes of track driving – is anything but ready for the track.”

The first class action suit was filed against GM in July 2017.

It is asserted in the lawsuit that GM breached its warranty in failing to repair defective Z06 vehicles.

“When Plaintiff and the other Class members purchased or leased their Z06s, GM expressly warranted in writing that the Z06s were covered by a Limited Warranty and that the Limited Warranty formed the basis of the bargain. GM expressly warranted that at ‘no charge’ it will repair ‘any vehicle defect.’ GM breached its warranty obligations by selling inherently defective Z06s.”
