A budget supercar should not mean budget engineering.
GM can’t go more than a few months without being in the spotlight for its engineering mishaps. This time 19 owners of C6 Corvettes have filed 20 claims against GM for fraud, negligence, and unjust enrichment because of excessive valve guide wear that causes their engines to fail. The cars affected include the 427 and Z06 models of the C6 Corvette. The suit doesn’t even include the current generation Corvette Z06, which has seen exceedingly high amounts of engine failures with some engines failing with only six miles on the clock.
The lawsuit claims that GM was aware of the issue but did not lift a finger to fix it because it would have cost them too much. This is not the first time GM has followed the same cut-corner philosophy to save some cash. GM has delivered a low-blow response to its customers by claiming that they were using bad gas and not following proper break-in procedures. But with both generations of Corvette facing similar issues, it can't just be a coincidence that all Corvette owners are terrible at maintaining their cars and filling them with the proper fuel. Hopefully this lawsuit will inspire owners of the current Corvette Z06 to go after GM for their self-sabotaging engines.
