FUEL SYSTEM, GASOLINE
2008 CORVETTE HAS A FUEL LEAK WHEN THE TANK IS 3/4 TO FULL. THE GAS VAPORS PERMEATE THE GARAGE AND THE COCKPIT. THIS IS A SAFETY CONCERN AS IT CAN CAUSE FIRE/EXPLOSIONS. *TR

ENGINE
I WAS CONCERNED ABOUT EXCESSIVE VALVE TRAIN NOISE AND AFTER READING SEVERAL ACCOUNTS OF IMPROPERLY MACHINED HEADS BY GM'S SUPPLIER LINAMAR, AND THAT NUMEROUS VEHICLES HAVE HAD VALVES DROP, RESULTING IN ENGINE FAILURE. AS A RESULT, AFTER HAVING BEEN REBUFFED BY CHEVROLET, I TOOK MY CAR WITH 36,000 MILES ON IT TO A CORVETTE SPECIALTY SHOP TO HAVE MY VALVE GUIDE CLEARANCE TESTED. I HAD SEVERAL EXHAUST VALVE GUIDES OUTSIDE THE MAXIMUM SERVICE SPECIFICATIONS, INDICATING THAT A CATASTROPHIC ENGINE FAILURE WAS IMMINENT. THE CAR WAS 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 LOSS OF STEERING, BRAKING CAPABILITY, AND WHICH CAN RESULT 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 WHILE THE VEHICLE IS UNDERWAY ON PUBLIC ROADWAYS. *TR

FUEL/PROPULSION SYSTEM
THERE IS A VERY STRONG FUEL SMELL IN MY CORVETTE AFTER FUELING UP. THE CABIN SMELLS LIKE RAW FUEL, AND IT PERMEATES THE GARAGE FOR A FEW DAYS. THE ISSUE SEEMS TO SUBSIDE AFTER THERE IS LESS FUEL IN THE CAR. *TR

ELECTRICAL SYSTEM, VISIBILITY/WIPER
MADE ONLINE CONCERN AND ISSUE WITH LOW BEAM LIGHTS GOING OFF IN 2011. RECALL NOTICE FROM GM; JANUARY 2015, STATES IT WILL INSTALL "JUMPER" WIRE. I ALREADY HAD THIS COMPLETED ON 10/13/2011 WHICH RESULTED AS A SHORT TERM FIX. STILL ENDED UP HAVING PROBLEMS AND EVENTUALLY (HOPING FOR THE RECALL TO TRANSPIRE SOONER) HAVE IT SET UP NOW WHERE I NEED TO POP THE HOOD AND INSTALL A 20 AMP FUSE IN ORDER FOR LIGHTS TO GO ON. "JUMPER" FORMAT IS NOT ADEQUATE JUST BE AWARE. THE DESIGN OF THE UBEC UNIT SHOULD BE OVERHAULED TO ACCOMPLISH TWO KEY ISSUES; HEAT AND LESS SHARP BENDS OF THE INTERNAL COPPER WIRING TO PREVENT STRESS AND BREAKING. CURRENTLY ONLY FOG LIGHTS FUNCTION WITHOUT HAVING TO PLUG IN THE 20 AMP FUSE. EVEN MY BRIGHT LIGHTS NEED THE FUSED PLUG IN UNDER THE HOOD. *TR

AIR BAGS
THE AIRBAG READINESS LIGHT REMAINED ILLUMINATED INTERMITTENTLY AFTER COMPLETING SELF CHECK DIAGNOSTICS THAT ARE INITIATED WHEN THE VEHICLE IS STARTED. THIS INDICATES THE SYSTEM MAY NOT BE WORKING PROPERLY AND MAY NOT INFLATE IN THE EVENT OF A CRASH OR COULD DEPLOY WITHOUT A CRASH. ALSO, THE SEAT BELT PRETENSIONER MAY NOT WORK PROPERLY. CHEVROLET DIAGNOSED THE PROBLEM IN DECEMBER, 2014. A CONNECTOR FROM THE SEAT BELT AND SIDE IMPACT AIR BAG SENSORS HAD DISLODGED FROM A RETAINED POSITION (CLIP ATTACHED TO A BAR) UNDERNEATH THE DRIVER'S SEAT. THE TECHNICIAN REATTACHED THE CONNECTOR USING THE CLIP TO THE FASTEN IT TO THE BAR UNDER THE SEAT AND CLEARED ERROR MESSAGES FROM THE COMPUTER. THIS ELIMINATED THE AIRBAG READINESS LIGHT. THE TECHNICIAN BELIEVED THAT THE MOVEMENT OF THE SEAT WITH THE CONNECTOR IMPROPERLY SECURED CAUSED THE PROBLEM. THE PROBLEM RECURRED ON JANUARY 2, 2015, ONCE UPON START UP, CLEARED, AND THEN AGAIN WHILE DRIVING. I CHECKED THE CONNECTOR AND IT AGAIN HAD DISLODGED. WHEN THE CONNECTOR IS ATTACHED TO THE BAR UNDER THE SEAT, THE CONNECTOR IT IS SO CLOSE TO THE FLOOR THAT WHEN THE SEAT IS MOVED, THE CONNECTOR DRAGS ON THE FLOOR, DISLODGING IT. THE SEAT MOVEMENT APPARENTLY RESULTS IN A LOSS OF CONTINUITY IN THE SYSTEM ILLUMINATING THE AIRBAG READINESS LIGHT. THE VEHICLE HAS A MEMORY SEAT AND HENCE, IT MOVES ITS FULL TRAVEL DISTANCE BACK UPON EXITING THE VEHICLE AND THEN RETURNS TO A PRESET POSITION UPON STARTING THE CAR. MY CONCERN IS THAT, ACCORDING TO THE OWNER'S MANUAL, THIS MAY DISABLE THE SIDE IMPACT AIR BAG, CAUSE IT TO DEPLOY WITHOUT A CRASH AND CAUSE THE SHOULDER BELT PRETENSIONER TO FAIL IN AN ACCIDENT. SINCE THE PROBLEM IS INTERMITTENT, THE PROBLEM COULD OCCUR AT ANY TIME. *TR

FUEL/PROPULSION SYSTEM
AFTER FILLING THE CAR WITH FUEL, I COULD SMELL GAS INSTANTLY AND I THOUGHT THERE WAS A LEAK. UPON PARKING MY CAR IN THE GARAGE THE WHOLE GARAGE SMELLED OF FUEL. AFTER TWO DAYS THE SMELL WAS GONE BUT IT DOES APPEAR EVERY TIME I FILL THE CAR TO SOME DEGREE. IT COMES AND GOES NOW SO YOU NEVER KNOW WHEN IT WILL HAPPEN. *TR

ENGINE
THE ENGINE EXHAUST VALVE GUIDES WERE OUTSIDE OF GM SPECIFICATIONS AND BOTH CYLINDER HEADS WERE REPLACED UNDER WARRANTY BECAUSE OF THIS. 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 A OIL SPILL ONTO THE ROAD IF THE ENGINE IS DESTROYED. 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. *TR

I TOOK MY CAR TO AMERICAN HERITAGE PERFORMANCE IN CALIFORNIA AND HAD THE HEADS CHECKED AND THEY WERE ALL OUT OF SPECK, AT 16000 MILES, AND THIS CAR WAS ONLY STREET DRIVEN, AND HAD TO HAVE ALL THIS WORK DONE ON A LOW MILEAGE CAR WAS VERY UPSETTING, AND IN THE END FINDING OUT THAT MANY CARS HAVE THIS PROBLEM. HAVING TO GET ALL THIS WORK DONE ON A VIRTUALLY NEW CAR IS RIDICULOUS.. *TR

CONCERNED ABOUT THE NUMBER OF DROPPED VALVES IN THE LS7 ENGINE USED IN THE CORVETTE Z06 THAT MAY RESULT IN A BLOWN ENGINE CAUSING A CRASH OR FIRE. I HAVE PRETTY MUCH PARKED MY 2008 Z06 DUE TO THIS CONCERN AS GM REFUSES TO ACKNOWLEDGE THAT THERE IS A PROBLEM BUT EMPIRICAL EVIDENCE ON PUBLIC USER FORUMS SHOWS THAT THERE IS A PROBLEM AND GM SHOULD ADDRESS AND FIX. I URGE THE NHTSA TO LOOK INTO THIS MATTER AS A MAJOR SAFETY CONCERN! *TR

ENGINE
ENGINE STARTED MAKING NOISE, FEELING THERE COULD BE A FAILURE I DROVE TO MY SERVICING CHEVROLET DEALER. THEY LISTENED TO THE ENGINE AND SAID, THAT'S NORMAL. NOT TRUSTING THAT JUDGMENT, I HAD AN INDEPENDENT SHOP INSPECT THE ENGINE, AND HAD THE VALVE ISSUE RESOLVED AT MY EXPENSE. I WAS STILL UNDER EXTENDED WARRANTY, WHICH MADE ME ANGRY. BUT IF THE DEALER SAYS THERE IS NOTING WRONG, WHAT AM I SUPPOSED TO DO? AFTER THE REPAIR WAS PERFORMED AT MY EXPENSE, I TOOK THE FAILING PARTS BACK TO THE DEALER FOR THEM TO INSPECT. THEY ADMITTED THEY WERE WRONG, BUT WHAT GOOD DID THAT DO ME? KEEP IN MIND MY VEHICLE HAD LESS THAN 10K MILES ON IT. THIS IS WHERE I FEEL SAFETY COMES INTO PLAY; HAD MY ENGINE FAILED AND LOCKED UP ON TODAYS CROWED INTERSTATES, I COULD HAVE CAUSED A MAJOR ACCIDENT. THE FAILURES I HAVE READ ABOUT, GAVE NO WARNING, WHEN THE ENGINE LET-GO. *TR

ENGINE
WHEN I PURCHASED THE 2007 CORVETTE Z06, I WAS INSTRUCTED TO HAVE THE HEADS CHECKED FOR EXCESSIVE VALVE GUIDE WEAR. I HAD THE HEADS PULLED AND THE VALVES EXAMINED BY A LOCAL EXPERT. HE INDICATED THAT THE VALVE GUIDES WERE OUT OF SPECIFICATION AND NEEDED REPLACEMENT. I REPLACED THESE AT MY OWN EXPENSE OF OVER $2000.00. HAD THE ENGINE BLOWN UP AS A RESULT OF THIS DEFECTIVE CONDITION, THE BREAKS AND POWER STEERING WOULD FAIL CAUSING AN ACCIDENT. I WOULD LIKE GM TO ISSUE A RECALL ON THIS MODEL CORVETTE. *TR

ENGINE
AT ONLY 21,179 MILES, MY DEALER INSPECTED BOTH CYLINDER HEAD BANKS AND FOUND VALVE GUIDE CLEARANCE TO BE WELL OUT OF MAXIMUM ALLOWED SPECIFICATION. THIS DEFECT PUTS UNDUE STRESS ON THE HOLLOW, SODIUM-FILLED EXHAUST VALVES. IF AN EXHAUST VALVE BREAKS, THE EXHAUST VALVE WILL DROP INTO THE COMBUSTION CHAMBER, AND CAUSE A COMPLETE, CATASTROPHIC FAILURE OF THE ENGINE. THIS CAUSES HAZARDOUS CONDITIONS FOR THE DRIVER, PASSENGER, AND SURROUNDING TRAFFIC: THE DRIVE WHEELS MAY BECOME LOCKED AS THE ENGINE SEIZES AND THE ENGINE BLOCK MAY BECOME WINDOWED BY A ROD, CAUSING A LARGE SPILL OF OIL AND COOLANT IMMEDIATELY UNDER THE VEHICLE ON THE ROADWAY. THESE CONDITIONS COULD LEAD TO A SEVERE ACCIDENT FROM A SUDDEN SPIN AND/OR A FIRE. I HAVE LITTLE CONFIDENCE THAT THE CYLINDER HEADS REPLACED ON MY CAR ARE FREE FROM THE VALVE GUIDE CLEARANCE DEFECT. AS MORE OWNERS HAVE BECOME AWARE OF THE PROBLEM, REPLACEMENT CYLINDER HEADS HAVE BEEN MEASURED BEFORE INSTALLATION ON THE ENGINE AND HAVE BEEN FOUND TO HAVE DEFECTS IN VALVE GUIDE CLEARANCE AND VALVE GUIDE TO SEAT CONCENTRICITY, SUCH AS WHAT COULD LEAD TO A DROPPED EXHAUST VALVE AND AN ACCIDENT. THE VEHICLES SHOULD BE RECALLED AND FIXED BEFORE ANY MORE SERIOUS ACCIDENTS OCCUR. ALTHOUGH MY VEHICLE DID NOT FAIL DESPITE HAVING THE DEFECT, I HAVE SEEN A VIDEO OF A SPIN CAUSED BY THE FAILURE, I HAVE SEEN PICTURES OF A VEHICLE AFTER A FIRE CAUSED BY THE FAILURE, AND I HAVE SEEN REPORTS OF APPROXIMATELY 35 FAILURES; ALL FROM CORVETTEFORUM.COM. THEREFORE I AM CONCERNED ABOUT MY SAFETY WHEN DRIVING THE VEHICLE AND I BELIEVE THE NHTSA SHOULD INVESTIGATE THE MATTER. *TR
