I would like to file a complaint due to safety concerns over bad heads and valves put into a percentage of these Corvette z06 cars. Gm has admitted there is an issue and yet refuses to do anything about it. There was a machining error with these heads and the engines can drop a valve without warning or symptoms and without pulling your motor apart there is no way to determine if your car is affected or not. The fact is now that an increasing percentage of these cars are losing their engines and replacement cost is over 17000. 00. Should the engine go it could lead to a serious crash from the rod puncturing the block and spreading oil under and around the car which not only affects the car in question but any others following it at highway speed. There have been some that have gone off the road because of this issue and it is taking any of the joy of owning or driving this car at all. Gm will not even tell anyone out of warranty what to do to address the problem and when some heads were replaced by gm for cars under warranty, some were found to have bad tolerances before even being installed. Gm has now gone on to their new model z06 and is simply hoping this issue goes away while throwing all their loyal customers under the bus so to speak. Something should be done before there is a death cause from this issue, not to mention a loyal customer losing a 17000. Engine through no fault of their own. I have contact Chevrolet several times and was met with little response or enthusiasm to do anything about the problem at all.
