  • 2015 - 2017 Chevy Corvette Z06

According to Hagens Berman's investigation into consumers' reports, Chevrolet has sold its model year 2015-2017 Corvette Z06 cars as track cars built to sustain high speeds, but Chevy failed to tell purchasers about the vehicle's lack of transmission and differential coolers, which can greatly diminish the track capabilities that consumers seek when they purchase the Z06. Corvette Z06 owners have reported this causes the car & to overheat and enter limp mode, while in use, even when the car is not being tracked. If you own an affected Chevy Corvette Z06 and have experienced overheating and limp mode, fill out the form to find out your consumer rights to compensation.


The Corvette Z06 reportedly enters limp mode, causing the car to fail to maintain desired speeds. Limp mode is a safety system designed to protect the engine from being damaged during extremely hot temperatures. Once limp mode engages, the engine will only run at very low RPMs and will be barely able to move.

Corvette owners report affected cars entering limp mode when in regular use. Owners have also reported that despite Chevy's promise to consumers that the Z06 was "conceived on the track and engineered alongside the C7.R race car," the vehicle is reportedly prone to overheating when driven at high speeds. Owners have cited Chevy's ads and promotion of the Corvette Z06 as a track car, but consumers were never warned that their vehicles would quickly overheat when tracked or driven at sustained high speeds.


Hagens Berman believes that consumers have the right to reimbursement for the premium price they paid for what they thought was a car capable of reaching and sustaining high speeds without failure. Nowhere does Chevy divulge these vehicles' failure to maintain high speeds to consumers. According to the firm's investigation, Chevy knew about the limp mode defect present in Corvette Z06 models and continued to market these vehicles extensively as fully functional, charging consumers high prices for vehicles that in no way uphold its promises.
