The current Chevrolet Corvette Z06 is referred to as a 650-horsepower supercharged monster and was meant to be a nightmare for all including Hellcats and Porsches on the track. So far so good. But, and there is always that ‘but’ to spoil the things. It turned out that this ‘nightmare’ has a well-documented problem with overheating.

Now Z06 owners have filed a class-action lawsuit against GM, explaining that the top-tier track rat of GM doesn’t deliver the performance they were promised.

After only 15 minutes of track use, the lawsuit claims, the defect can put the Corvette Z06 into “limp mode”.

Fifteen minutes! A hell of a track day! A sudden loss of power can create a dangerous situation on track and “Limp mode” does precisely that – it reduces the car’s power and speed drastically. It’s dangerous because the speeding traffic around a limping car may not expect that car to slow down.

Almost always track day sessions take longer than 15 minutes, so you can’t get all of the track time you paid for. This is a problem indeed.
The suit, filed by Hagens Berman’s 76-attorney law firm based in Seattle, claims that besides going into a limp mode on track, the 2015-2017 Z06 can do that on public roads as well so it’s a problem for all Z06 owners, not only to those who use their Z06 on track. The defect in question warps important engine components because of the high temperatures, causing additional costly repairs.

As it is claimed in the lawsuit, which was filed in the U.S. District Court for the Southern District of Florida, GM knew of the problem but failed to disclose it no matter what.
The managing partner of the firm, Steve Berman, explained in a statement that owners are suing over GM’s “bait and switch” taken that the Z06 was marketed and sold as a car built for track use. Here’s what he said:
“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. 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.

The defect in question markedly limits the car’s performance – the sole reason these hot rod enthusiasts bought the Corvette Z06 in the first place. If they’d known of this defect at the time of purchase, they likely wouldn’t have spent six figures on the Z06. “
Attorneys estimate that over 30,000 2015-2017 model year Corvette Z06s are affected by this defect and the lawsuit claims that GM violated state and federal laws. It requests financial compensations for affected owners, included for the diminished value of the car now that many people associate the Z06 with overheating problems on the track.

The 2017 model had several upgrades to its cooling system because of the problems reported with the car, but, this year’s model can be also found on the list of affected cars in this lawsuit.
