THE LAST 2 DAYS WHEN I DRIVE AT NIGHT THE HEADLIGHTS (LOW BEAMS) SHUT OFF. I SWITCH TO THE HIGH BEAMS AND THEY WORK. THIS HAS HAPPENED IN THE DARK AND IS DANGEROUS BECAUSE IT HAPPENS ABOUT 30 OR 40 MINUTES AFTER DRIVING THE CAR. I LET THE CAR SIT FOR 4 OR 5 HOURS AND THEN COME BACK AND THEY START WORKING. IT IS THE UNDERHOOD BUSSED ELECTRICAL CENTER (UBEC) HOUSING I SUSPECT.

VEHICLE IS ALWAYS STATIONARY WHEN IT GETS STUCK IN PARK, AND UNABLE TO SHIFT INTO GEAR. I LET IT SET FOR A FEW MINUTES THEN PUSH START AGAIN. SOMETIMES IT WILL SHIFT INTO GEAR AND OTHER TIMES IT WILL NOT. 50/50 CHANCE ONE WAY OR THE OTHER. THIS HAS HAPPENED SEVERAL TIMES SINCE I INHERITED THIS VEHICLE FROM MY FATHER IN EARLY 2017 WITH 48,000 MILES ON IT. FAST FORWARD TO TODAY 03/09/2018 VEHICLE DOES NOT GO INTO PARK BUT IS "STUCK" IN NEUTRAL, DOES NOT GO INTO PARK OR ANY OTHER GEAR.

MY 2007 CHEVROLET CORVETTE Z06 DROPED A VALVE WHILE I WAS DRIVING HOME. I WAS ON A REGULAR 45MPH SPEED LIMIT ROAD IN TRAFFIC WHEN I REALIZED THE CAR WAS LOSING POWER AND QUICKLY PULLED ON THE SIDE OF THE ROAD BECAUSE THERE WERE CARS IN FRONT AND BEHIND ME. LUCKILY NOBODY WAS HURT BUT IF I HAD BEEN ON A HIGHWAY IN THE MIDDLE LANE SOMEONE COULD HAVE LOST THEIR LIFE INCLUDING ME. FROM THE SECOND I REALIZED THE CAR WAS LOSING POWER TO THE POINT THE ENGINE SHUT OFF WAS A MATTER OF 5 SECONDS MAYBE. AFTER DOING MUCH RESEARCH ONLINE I FOUND OUT THERE IS A VERY COMMON PROBLEM WITH VALVE GUIDES BEING OUT OF SPEC IN THIS MODEL CORVETTE.

THERE IS A LEAK AT THE TOP OF MY FUEL TANK. WHENEVER THE TANK IS 3/4 FILL OR GREATER, FUEL SLOSHES OUT OF THE TOP OF THE TANK AND POOLS ON TOP OF THE TANK AND SOMETIMES DRIPS DOWN ONTO THE EXHAUST.. PARKING THE CAR OVERNIGHT IN THE GARAGE IS FILLING MY GARAGE WITH FUEL VAPORS AND I AM CONCERNED THE DRIPPING FUEL MAY BE A FIRE RISK.

I WAS 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, I TOOK MY CAR WITH 27000 MILES ON IT TO A CORVETTE SPECIALTY SHOP TO HAVE MY VALVE GUIDE CLEARANCE TESTED. I HAD (2) INTAKE VALVE GUIDES OUTSIDE OF SERVICE SPECIFICATIONS, (4) EXHAUST VALVE GUIDES OUTSIDE OF SERVICE SPECIFICATIONS, AND A COMBINATION OF (10) OTHER INTAKE AND EXHAUST VALVE GUIDES AT OR NEAR THE MAXIMUM OUTSIDE OF SERVICE SPECIFICATIONS. THE CAR IS BEING REPAIRED WITH PROPER RE-MACHINING OF THE HEADS TO MAKE THE VALVE GUIDES CONCENTRIC, NEW INTAKE AND EXHAUST VALVE GUIDES INSTALLED, AS WELL AS NEW SEALS, VALVES, SPRINGS, ETC. 88% OF THE CORVETTE FORUM MEMBERS WHO HAVE HAD THEIR CYLINDER HEADS TESTED FOR EXCESSIVE VALVE GUIDE WEAR, WERE OUT OF SERVICE SPECIFICATIONS.

I'VE READ SEVERAL DIFFERENT POSTS ABOUT PEOPLE WITH 2007 CORVETTES HAVING PROBLEMS WITH VALVES AND DROPPING VALVES AND LOSING CONTROL WHEN THIS BECAUSE OF THE POWER STEERING AND BRAKES NOT WORKING WHEN THIS HAPPENS. I BOUGHT MY 2007 CORVETTE Z06 NEW BACK IN 2007 AND I'VE ALWAYS NOTICED VALVE NOISE AND LATELY IT SEEMS A LITTLE LOUDER. I HEAR THE VALVE NOISE MOSTLY DRIVING IT IN TOWN. I'M NOT SURE IF I SHOULD JUST WAIT FOR THE VALVES TO FAIL AND TAKE MY CHANCES OR PAY TO HAVE SOMEONE TO PULL THE HEADS AND CHECK ALL THE VALVES AND REPAIR ANY ONES THAT ARE OUT OF SPECIFICATION. SO I THINK IT'S GM'S RESPONSIBILITY TO DO A RECALL FOR THIS BECAUSE IN MY OPINION THIS IS A DEFECT AND IT WOULD BE VERY DANGEROUS TO DROP A VALVE AND LOSE CONTROL OF MY CAR. I SPENT A LOT OF MONEY ON THIS CAR AND I JUST DON'T FEEL I SHOULD NEED TO PAY ANYMORE MONEY TO DIAGNOSE AND FIX THIS PROBLEM. MY HEADLIGHTS STOPPED WORKING TONIGHT AND LUCKILY THERE IS A RECALL FOR THAT PROBLEM.

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.

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.

WHEN I HAD THE MOTOR CHECKED PROACTIVELY THE EXHAUST VALVE GUIDES WERE OUTSIDE OF GM SPECIFICATIONS. THIS DEFECT CAN CAUSE THE HEAD OF A VALVE TO SNAP OFF AND DESTROY THE ENGINE. THE ENGINE WILL STOP WORKING IMMEDIATELY, CAUSING THE POWER STEERING AND POWER BRAKES SYSTEMS TO FAIL. THE VALVE FAILURE CAN CAUSE AN OIL SPILL ONTO THE ROAD IF THE ENGINE IS COMPROMISED. THERE HAVE BEEN NUMEROUS DOCUMENTED CASES OF ENGINE FAILURE AS A RESULT OF A DROPPED VALVE INTO A CYLINDER. THIS CAN CAUSE A CATASTROPHIC ACCIDENT OR FIRE. 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. I WAS FORCED TO SPEND IN EXCESS OF $3K TO INSURE I DID NOT HARM ANYONE OR MYSELF. BEST REGARDS *TR

AFTER MONTHS OF READING ABOUT THE EXHAUST VALVE ISSUE WITH CORVETTE Z06S I TOOK MY CAR AND HAD THE HEADS CHECKED. THE SHOP FOUND THE VALVE GUIDE CLEARANCE TO BE OUTSIDE THE SPECIFIED ACCEPTABLE RANGE. THE DEFECT PUTS UNDUE STRESS ON THE SODIUM FILLED VALVES AND IF THE VALVE FAILS IT CAN CAUSE CATASTROPHIC ENGINE DAMAGE AND POTENTIALLY DEADLY SITUATION IF THIS OCCURS AT SPEED ON THE ROADWAY AS THE DRIVER WILL LOSE ABILITY TO CONTROL THE VEHICLE POTENTIALLY CAUSING A DEADLY ACCIDENT. I PAID SEVERAL THOUSAND DOLLARS OUT OF POCKET TO FIX THIS ISSUE DESPITE GM ACKNOWLEDGING THERE IS AN ISSUE WITH THESE VEHICLES.

THIS MODEL CORVETTE CAN SUDDENLY DROP AN ENGINE VALVE (EXHAUST OR INTAKE) AND UNEXPECTEDLY DEVELOP A HOLE IN THE BLOCK ACCOMPANIED WITH OIL SPILLED ON THE ROADWAY, SMOKE BILLOWING WITH RISK FOR VEHICLES BEHIND AND IN FRONT, AND THE RISK FOR TOTAL LOSS OF POWER STEERING, BRAKING AND CONTROL OF THE VEHICLE. THE OUTCOME IF THIS HAPPENED ON A FREEWAY WITH CARS TRAVELING AT A HIGH RATE OF SPEED IS POTENTIALLY FATAL. ALL OF THIS IS DUE TO MACHINING ERRORS AND SUPPLIER DEFECTS FOR THE ASSOCIATED PARTS (VALVES, GUIDES, ETC.) ON ALL 2006-2013 CORVETTE C6 Z06'S MADE BY GM. *TR
