NHTSA Complaint #10955020 — 2009 CHEVROLET CORVETTE

I WAS CONCERNED ABOUT EXCESSIVE VALVE TRAIN NOISE AND AFTER READING SEVERAL CORVETTE FORUM THREADS AND SPEAKING TO NUMEROUS CHEVROLET MECHANICS ABOUT IMPROPERLY MACHINED HEADS BY GM'S SUPPLIER LINAMAR, AND THAT NUMEROUS VEHICLES HAVE HAD VALVES DROP AND RUIN THE ENGINES. THIS HAS HAPPENED ON COMPLETELY STOCK VEHICLES. PEOPLE WITH LESS THAN 20000 MILES HAVE LOST MOTORS. 88% OF THE CORVETTE FORUM MEMBERS WHO HAVE HAD THEIR CYLINDER HEADS TESTED FOR EXCESSIVE VALVE GUIDE WEAR, WERE OUT OF SERVICE SPECIFICATIONS. SOURCE: HTTP://WWW.CORVETTEFORUM.COM/FORUMS/...-REGISTRY.HTML GM NEEDS TO ISSUE A RECALL ON THIS ISSUE, THERE HAVE BEEN NUMEROUS ENGINE FAILURES AS A RESULT OF A DROPPED VALVE INTO A CYLINDER WHICH CAN CAUSE ACCIDENTS AND FIRES. GM IS VERY AWARE OF THIS ISSUE, BUT REFUSES TO DO ANYTHING ABOUT THIS HUGE SAFETY RISK TO DRIVERS, PASSENGERS, AND NEARBY VEHICLES IF THE ENGINE FAILS GOING DOWN THE ROAD. IF THE ENGINE FAILS DUE TO DROPPING A VALVE, THE ENGINE WILL IMMEDIATELY SHUT OFF, WHICH CUTS OFF POWER STEERING AND POWER BRAKING. THIS IS A VERY HUGE SAFETY CONCERN.
