Corvette Z06 Owners Sue GM For Allegedly Selling Defective Cars

Chevrolet recently implemented a host of cooling improvements on the 2017 Corvette Z06 but that isn’t sitting well with lawyers who are accusing the company of selling customers “unreliable cars with a performance-limiting defect.”

According to a class action lawsuit by Hagens Berman Sobol Shapiro LLP, the Corvette Z06 cannot be operated safely on a racetrack as the vehicles are prone to overheating and entering into limp mode. When this occurs, the Corvette’s power is “drastically reduced” and the lawsuit claims this creates a dangerous situation when the car is surrounded by other speeding vehicles.

The lawsuit says GM deceived customers and violated state and federal laws by failing to ensure the Z06 functions safely. It also alleges the company committed fraudulent concealment, breach of warranty, and unjust enrichment.

In a statement, managing partner Steve Berman 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.” Berman added “The defect in question markedly limits the car’s performance – the sole reason these hotrod 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.”

The law firm estimates there could be more than 30,000 affected models from the 2015-2017 model years.

GM hasn’t commented on the lawsuit but when the cooling improvements were announced, Corvette executive chief engineer Tadge Juechter told Motor1 only a small number of customers reported overheating issues and the exact number might have been less than five percent.

      Could be worse. Remember when the GT3 and M5 came out? My friend got his M5 new and couldn’t drive it for almost 2 months.

      American AUTO engineering along with German AUTO engineering seems to still lag behind the Japanese in reliability/quality.

    Good for the owners. Now go get 911 GT3’s and stop fooling around.

    I don’t think they can really make the safety claim, as the cars easily surpass all road standards and laws. However, you can claim false advertising and substandard performance for track use. If GM already implemented cooling improvements on the 2017 model car, they should simply offer these upgrades free of charge to any existing C7 Z06 owners. Many won’t even request it. And since they already fit the car, this would likely be one of the cheapest “recalls” ever on record. It has to be cheaper than the cost of lawyers combined with the bad press. Aside from this blemish, the Corvette has easily been the world’s most reliable sports car since the ’90s. It would be a shame to ruin that reputation over a few thousand cooling upgrades.

    Hmm, so is this true? Does the Z06 have governors on its engine? Can someone with knowledge of this issue chime in please?

  • Puddingpopper

    I can haz race car?

    they only have a major lawsuit if, the percentages of the so called overheating does indeed occur, are much higher in number than a particular average in comparison to other current model high performance “good for track day” cars, which could be of another brand from what I understand, not just Z06’s by GM.

    good luck suing you leaches.

    I love Corvettes but obviously GM skimped a little too much with the cooling system. That’s why they have the improvements available now. My friend and I drove one at exotics racing in Vegas. Awesome car! But after each 5 lap run, the engine compartment was opened up and the engine compartment was cooled off with a hose. After my friend drove it he got an extra lap out of it because they had to do a cool down lap. It didn’t go into limp mode but the instructor said it was mighty close to it and that it had in the past. The supercharger is too small for the engine too. The larger blowers have larger capacity liquid/air intercoolers which help. In addition to a larger radiator and more airflow, it should keep things quite a bit cooler for longer. I think the problem is room under the hood. There just isn’t enough of it. I thought it would be a better idea to just get a Grand Sport and install a procharger i1 supercharger. That blower is separate from the engine block and has an air/air intercooler so it’s using (and heating up) the engine coolant. You might only get 600hp/600tq with no other modifications but it would be more reliable power and you wouldn’t have all the heat issues.

    A pity. The car is gorgeous.

    I’m not a Vette fan but I do like the C7 Stingrays, such a gorgeous car and it’s a shame that this is happening. Could be leaches trying to get money or it may very well be legitimate, I can’t make any statements other than guestimates but time will tell and I’m pretty sure that GM will make things right since this is their flag ship performance car that is the center of attention. All automakers go through some rough patches where there are lemons built or reliability is a factor within the drive train.
