2008 CORVETTE C6 Z06. CONSUMER WRITES IN REGARDS TO VALVE GUIDE MACHINING ISSUES. *LD *JS

FILLED GAS TANK TO FULL & HAD STRONG GAS ODORS INSIDE & OUTSIDE VEHICLE. GAS & GAS SMELL COMING FROM EXHAUST WHEN CAR IS STARTED & RUNNING. DEALER IDENTIFIED LEFT SIDE FUEL PUMP MODULE NEEDS TO BE REPLACED.

LOUD TICKING COMING FROM VALVES, WORRIED TO DROP A VALVE WHEN DRIVING

DEFECTIVE VALVE GUIDES. THIS FIRST HAPPENED AT 13,500 MILES, AND CHEVROLET DID REPLACE THE HEADS UNDER WARRANTY. NOW IT HAS HAPPENED AGAIN AT 28500 MILES AND I HAVE SPENT OVER $3100 IN PARTS ALONE TO FIX THE PROBLEM, WHICH HAS BEEN VERIFIED BY THE COMPANY WHO SOLD ME THE REPLACEMENT HEADS. I PROVIDED THE LABOR OR THE COST WOULD HAVE BEEN $1700 HIGHER. FOUR INTAKE VALVE GUIDES WERE BEYOND THE CHEVROLET REPLACEMENT SPEC AND ANOTHER FOUR WERE ALREADY AT THE CHEVROLET SERVICE LIMIT WITH ONLY 15000 MILES ON THE REPLACEMENT HEADS. OBVIOUSLY THE PROBLEM OCCURRED DURING CITY AND HIGHWAY DRIVING.

TL* THE CONTACT OWNED A 2008 CHEVROLET CORVETTE Z06. WHILE DRIVING 45 MPH WITH THE CRUISE CONTROL ACTIVATED, THE INSTRUMENT PANEL INDICATED THAT THE FRONT DRIVER SIDE TIRE PRESSURE WAS HIGH AND THEN LOW. THE MESSAGE "SERVICE ACTIVE HANDLING" FLASHED ACROSS THE INSTRUMENT PANEL. THE VEHICLE THEN SLID TO THE LEFT, SPUN 360 DEGREES, AND CRASHED INTO THE MEDIAN AND SEVERAL TREES. THE CONTACT WAS KNOCKED UNCONSCIOUSNESS AND THE PASSENGER WAS FATALLY INJURED. THE CONTACT WAS INJURED AND TRANSPORTED TO A HOSPITAL VIA AMBULANCE. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOTALED AND TOWED. THE CONTACT WAS ADVISED BY HIS ATTORNEY NOT TO SPEAK TO ANYONE; THEREFORE, THE DEALER AND MANUFACTURER WERE NOT CONTACTED. THE FAILURE MILEAGE WAS 60,000.

PRIMARY TANK MODULE FLANGE FUEL AND VAPOR LEAK ON TOP OF PRIMARY FUEL PUMP CAUSING HAZARDOUS FUMES IN GARAGE AND CAR.

SEVERE GAS SMELL LEFT IN A CLOSED AREA AFTER CORVETTE USE. WHEN THE CAR IS DRIVEN AND THEN PARKED IN A GARAGE, THE GARAGE SMELLS SEVERELY OF FUEL. IF AIRED OUT, THE SMELL DISSIPATES. IF NOT, THE ODOR IS OVERWHELMING. UPON REVIEW, IT APPEARS THE SMELL IS COMING FRONT THE DRIVERS SIDE LEFT-HAND FUEL TANK. THE LEAK AFFECTS THE SAFETY OF THE CAR PASSENGERS AS THE GASOLINE LEAK FROM THE TANK DRIPS ONTO THE EXHAUST. MY MOTHER IS 94 YEARS OLD AND HAS RIDDEN WITH ME WHILE THIS ISSUE WAS OCCURRING. LITTLE DID I UNDERSTAND THE POTENTIAL IMPACTS ON MY FAMILIES WELL-BEING. I BELIEVE THIS IS A MAJOR SAFETY HAZARD WITH THIS CAR. UPON CURSORY REVIEW OF ONLINE CORVETTE CHAT GROUPS, THIS SEEMS TO SPECIFICALLY AFFECT THIS MODEL CORVETTE. AFTER FURTHER RESEARCH, THIS PROBLEM SEEMS TO BE PREVALENT IN PAST CORVETTE MODELS EXTENDING BACK TO 1997. UPON CONTACTING GM/CHEVROLET SERVICE DEPARTMENT WE WERE TOLD THAT OUR SPECIFIC VIN NUMBER DOES NOT QUALIFY FOR A RECALL. IT'S MY UNDERSTANDING THERE IS AN EXTENSION OF THE WARRANTY ON THIS SPECIFIC ISSUE DUE TO ITS PREVALENCE. I ALSO UNDERSTAND THAT THE EXTENSION INCLUDED MILEAGE TO 80,000 MILES AND THROUGH AUGUST 17, 2017. MY MILEAGE CURRENTLY SITS AT 49,000 MILES AND WE SUPPOSEDLY MISSED THE DEADLINE BY 11 DAYS AS WE REPORTED THIS ISSUE TO THE DEALERSHIP ON AUGUST 28, 2017. WHILE WE DID PURCHASE THE CAR USED, WE NEVER WERE TOLD OF THE ISSUE NOR RECEIVED PAPERWORK TO THAT AFFECT SO WE WERE COMPLETELY UNAWARE OF SUCH A HAZARD. I STRICTLY USE DEALERSHIPS F

I BOUGHT MY 2008 Z06 BACK IN DECEMBER 2016 WITH 27000 MILES ON IT. LOVE THE CAR BUT FROM I UNDERSTAND READING ABOUT THE COMPLAINS FROM OTHER OWNERS IT HAS VALVE PROBLEMS AND THE CAN GIVE AWAY AT ANY TIME. DEAR GM I DON'T CARE HOW YOU TAKE THIS, BUT SHOULD MY 2008 LS7 MOTOR BREAK DOWN DUE TO THIS SPECIFIC SITUATION YOU WILL FIX IT AT YOUR OWN COST, I AM PRINTING THE COMPLAINS FROM THE FORUM ABOUT THE LS7 MOTOR ISSUES, AND IF THAT EVER HAPPENS TO MY CAR AND YOU REFUSE TO FIX IT, TV STATIONS, RADIO STATIONS, AND NEWS PAPERS WILL KNOW ABOUT THIS. LET ME CLEAR THIS IS A STATEMENT I AM MAKING THANK YOU

ENGINE IS MAKING A LOUD TICKING NOISE. SHOP RECOMMENDED TO REPLACE VALVE GUIDES AND REMACHINE CYLINDER HEADS. THIS IS TO PREVENT A VALVE DROPPING INTO THE ENGINE DUE TO OUT OF SPEC CYLINDER HEADS FROM THE OEM SUPPLIER. THIS IS A HIGH OCCURRENCE PROBLEM THAT HAS LOW OR REMOTE DETECTION METHODS. THE SEVERITY PRESENTS A POTENTIAL SAFETY/FIRE HAZARD.

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 9500 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. 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.

STRONG GASOLINE SMELL COMING FROM VEHICLE AFTER DRIVING WHEN PARKED IN GARAGE. *TR

THE 7L 427 ENGINE HAS A VALVE FAILURE PROBLEM. THE VALVE HEADS BREAK OFF INSIDE THE ENGINE WHILE RUNNING. THIS HAPPENED TO ME AS I WAS DRIVING ALONG A HIGHWAY AT 60 MILES PER HOUR NOT ACCELERATING BRAKING OR TURNING, IN A VERY REMOTE PART OF TEXAS. THE ENGINE SEIZED UP. THIS IS A KNOWN ISSUE BY GM WITH A MUCH HIGHER THAN EXPECTED FAILURE RATE YET HAS NEVER HAD A SERVICE BULLETIN NOR RECALL. THE CAR HAD 18,000 MILES ON IT AT THE TIME AND HAD NEVER BEEN TO THE TRACK OR ABUSED IN ANY WAY. OIL WAS CHANGED AT 3,000 MILE INTERVALS BY A CERTIFIED SHOP. BETWEEN TOWING AND REPAIR THE TOTAL BILL WAS OVER $ 16,000. BECAUSE THE CAR HAD BEEN IN SERVICE OVER 5 YEARS DESPITE THE LOW MILEAGE, GM PICKED UP ONLY 45% OF THE COSTS LEAVING ME WITH OVER A $ 10,000 BILL. THIS IS A HIGH PERFORMANCE VERY EXPENSIVE SPORTS CAR THAT HAD A COMPLETE ENGINE FAILURE AT 18,000 MILES. *TR

YES ,WHEN DRIVING THE CORVETTE ON THE HIGHWAY AND THE ENGINE BLEW UP AND QUIT WORKING EVERYTHING POTENTIALLY CAUSING AN ACCIDENT TO ME AT THAT TIME I WAS VERY SCARED.........THE VALVE DROPPED THROUGH THE 8TH CYLINDER,WHILE DRIVING ALMOST CAUSING DRIVERS TO CRASH. *TR

STRONG SMELL OF GASOLINE ON LEFT SIDE OF CAR. NO VISIBLE LEAK ON THE FLOOR

FUEL SMELL COMING FROM THE LEFT SIDE OF THE VEHICLE. ONLY HAPPENS WHEN FUELED ABOVE 3/4 OF A TANK. CHEVROLET DEALER WAS CONCERNED ABOUT THE PROBLEM DURING AN OIL CHANGE AND TRIED TO GET GM TO CORRECT THE ISSUE BUT THEY WOULD NOT CITING THAT THE VEHICLE PASSED ALL FUEL PRESSURE AN LEAK TESTS. THE VEHICLE IS DANGEROUS TO PARK IN A GARAGE OR CLOSED AREA DUE TO THE VERY GOOD CHANCE OF IGNITION FROM STRONG FUMES. JUST AS DISTURBING IS THE FACT THAT THE EXHAUST SYSTEM IS BY THE SOURCE OF THE LEAK AND COULD IGNITE AT ANY TIME WHILE DRIVING. MANY OTHER CUSTOMERS HAVE COMPLAINED OF THIS ISSUE WITHOUT A RESOLUTION FROM THE MANUFACTURER OR IF GM HAS AGREED TO REPLACE THE DEFECTIVE PART (FUEL PUMP) THEY DO SO WITH THE SAME TYPE THAT HAS ALREADY FAILED. EVENTUALLY ONE OF THESE CARS IS GOING TO EXPLODE OR CATCH FIRE AN I GUESS THAT ONLY THEN WILL THE MANUFACTURER AND THE GOVERNMENT DO SOMETHING ABOUT IT. I HAVE ATTACHED THE SERVICE REPORT WHERE THE DEALERSHIP ACKNOWLEDGED THE SMELL AND THE NOTICE FROM CHEVROLET. SOMETHING NEEDS TO BE DONE ABOUT THIS BEFORE THERE ARE INJURIES OR DEATHS BECAUSE OF THIS.

WHEN FUEL TANK IS FULL THERE ISAVERY STRONG SMELL OF FUEL. SO FAR NO LEAK ON GROUND. SMELL SO BAD CAN BE NOTIED FOUR CARS AWAY.

VEHICLE IS COMPLETELY STOCK WITH ONLY 18,000 MILES ON IT. IT HAS NEVER BEEN ON A TRACK OR USED FOR ANYTHING OTHER THAN A WEEKEND TOY. COMPLETE ENGINE FAILURE AS A RESULT OF A VALVE BREAKING OFF INSIDE THE ENGINE WHILE DRIVING CASUALLY AT 50 MPH. AS A RESULT THE ENGINE STOPPED RUNNING TAKING WITH IT THE POWER STEERING AND POWER ASSISTED BRAKES. I WAS ON A COUNTRY ROAD APPROXIMATELY 45 MILES FROM THE NEAREST GAS STATION OR SERVICE FACILITY OF ANY KIND. THERE WAS ALSO NO CELL PHONE SERVICE AND WAS LEFT STRANDED. I HAVE SINCE HAD A BRAND NEW ENGINE PUT IN AT A TOTAL COST OF OVER $ 16,000.

RECENTLY MY LOW BEAM HEADLIGHTS WOULD RANDOMLY STOP WORKING. AT FIRST THEY WOULD GO OFF AND COME BACK ON AFTER A COUPLE MINUTES BUT NOW I'L BE LUCKY IF THEY TURN ON AT ALL. THE PROBLEM COMES FROM THE FUSE BOX LOCATED UNDER THE HOOD. IN THE BEGINNING I WOULD GET OUT OF MY CAR AND PLAY AROUND WITH THE LOW BEAM RELAY UNTIL THE LIGHTS CAME ON AND STAYED ON BUT NOW THAT DOES NOT EVEN HELP. ITS OBVIOUSLY A PROBLEM DUE TO THE FUSE BOX. I KNOW THERE ARE MANY OTHER CORVETTE OWNERS WHO HAVE THE SAME ISSUE. I HOPE GM WILL FIX THIS PROBLEM.
