Chevrolet Corvette Z06 Owners File Another Lawsuit Against GM


That overheating while on track issue is still affecting some owners.

Last summer we learned about a class action lawsuit filed against General Motors by certain C7 Corvette Z06 owners claiming the vehicle cannot be operated safely on the racetrack despite being advertised with "track-proven structure and technologies." GM was accused of being aware of a defect where the engine overheats and enters limp mode after only 15 minutes of on-track driving. Limp mode means speed and power are "drastically reduced" and that poses a clear safety risk at high speed with other cars on the track.

At the time, an estimated 30,000 Z06s built from 2015 to 2017 were suspected of being defective. The same law firm, Hagens Berman, has filed another class action suit against GM on behalf of more affected C7 Z06 owners hailing from 11 US states. This time it also adds "implied warranty claims to the list of complaints against GM." If there is a fix to this supposed issue, then GM has yet to come up with it. "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,'" said Steve Berman, managing partner of Hagens Berman.

"What Z06 owners received from GM – a car that peters out after 15 minutes of track driving – is anything but ready for the track." One owner named in the suit reportedly has had only three track days, and the car overheated every time. Interestingly, another owner forked over $2,000 for dealership-installed upgrades for this overheating defect. Unfortunately they didn't work, and now his Z06 only runs on high-octane gasoline, which costs $100 for a fill up. He also completed only two laps before it overheated the last time he tracked it. "To add insult to injury, when notified about the Z06 cooling system defect, GM chose to ignore the issue altogether," Berman added.
