19 owners of the 2006 - 2014 Chevrolet Corvette Z06 and 427 models have filed a class-action lawsuit against General Motors against an engine issue. The lawsuit says the 7.0L V8 fitted in these models have excessive valve guide wear that leads to engine failures. The suit goes on to say that GM is aware of this problem, but hasn't come up with a solution.
According to Law360, General Motors began testing vehicles equipped with the V8 and were able to replicate the problem. The issue is that GM didn't go any further with the tests as it “would lead to more repair and investigations than it wished to perform.”
If this suit goes forward, it might lead to lawsuits dealing with the new Corvette Z06 and its engine issues. As The Truth About Cars points out, a number of outlets have had issues with the Z06's engine.
- Towards the end of last year and early this year, a number of Z06 owners were having their engines fail with under 1,000 miles on the odometer.
- Gary Gastelu of Fox News in July had his Z06 tester experience engine failure
- In response, GM asked owners to follow the break-in procedure and change the oil when the vehicle hits 500 miles.
[*]Motor Trend in their 'Best Drivers Car' test had the Z06 in DNF due to engine issues.
- "It didn't work. The damn Z06 retarded spark by 8 degrees, and the 1.7-liter TVS supercharger refused to make boost. No one knows why," wrote Motor Trend’s Jonny Lieberman.
- General Motors said the problem was bad gas, but this seems somewhat dubious as all of the vehicles - including two other GM products (Cadillac ATS-V and CTS-V) got the same gas.
