NHTSA Complaint #10762738 — 2007 CHEVROLET CORVETTE Z06

I AM EXTREMELY CONCERNED ABOUT EXCESSIVE VALVE TRAIN NOISE AND AFTER READING SEVERAL CORVETTE FORUM THREADS ABOUT IMPROPERLY MACHINED HEADS BY GM'S SUPPLIER LINAMAR, AND THAT NUMEROUS VEHICLES HAVE HAD VALVES DROP AND RUIN THE ENGINES CAUSING A LOSS OF CONTROL OF THE VEHICLE DUE TO THE ENGINE STOPPING ABRUPTLY. 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/C6-Z06-DISCUSSION/3386141-THE-OUT-OF-SPEC-GUIDE-WEAR-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 SEVERE 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. IT HAS BEEN NOTED ON THE FORUM THAT GM IS VERY AWARE OF THE ISSUES AND I ASSUME THEY THINK NO ONE WILL REPORT THEM FOR NOT HANDLING IT CORRECTLY. THE ISSUE IS THIS IS A CRITICAL SAFETY ISSUE FOR ANYONE DRIVING A 06-13 Z06 MODEL ON THE ROAD. I AM TO THE POINT I DON'T FEEL SAFE TO DRIVE MY VEHICLE ANYMORE DUE TO THE LOUD 'TICKING' VALVE-TRAIN AS IT IS (SYMPTOM) MEANING IT IS LIKELY TO FAIL AT ANY MOMENT SEIZING THE ENGINE WHILE ON THE ROAD. I HAVE WAITED ON GM FOR 6 YEARS TO DO THE CORRECT THING ON THEIR OWN BUT I AM NOW REPORTING IT DUE TO THEIR GROSS NEGLIGENCE AND DISREGARD OF THEIR CUSTOMERS SAFETY.
