ENGINE
MY CYLINDER HEAD INTAKE AND EXHAUST VALVES WERE SEVERELY OUT OF GM'S .0037" MAXIMUM WIGGLE TOLERANCE. THE VALVES WERE TESTED BY YUMA AUTO AND TRANS AS WELL AS AMERICAN HERITAGE PERFORMANCE (HARBOR CITY, CA). NOT ADDRESSING THE ISSUE MAY HAVE CAUSED A DROPPED CYLINDER VALVE AND BLOWN ENGINE.

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. 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 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.

MY SON'S CAR BLEW UP WHILE TRAVELING ON THE FREEWAY ALMOST CAUSING AN ACCIDENT. HE WILL FILE A SEPARATE COMPLAINT. THERE IS A SYSTEMIC PROBLEM WITH THE Z06 AND THE 427 ENGINE SO I HAD MY HEADS CHECKED AS A PREVENTATIVE MEASURE AND THEY WERE FAR ENOUGH OUT OF SPEC THAT SELF DESTRUCTION WAS IMMINENT. THE HEADS WERE CHECKED AND REPLACED BY A CHEVROLET DEALER. THERE ARE HUNDREDS OF EXAMPLES OF THIS PROBLEM ON THE CORVETTE FORUM AND IT'S ONLY A MATTER OF TIME BEFORE SOMEONE GETS SERIOUSLY INJURED. I SINCERELY HOPE YOU WILL LOOK INTO THIS PROBLEM IN TIME TO PERHAPS SAVE SOMEONE'S LIFE. *TR

ENGINE
I WOULD LIKE TO FILE A COMPLAINT DUE TO SAFETY CONCERNS OVER BAD HEADS AND VALVES PUT INTO A PERCENTAGE OF THESE CORVETTE Z06 CARS. GM HAS ADMITTED THERE IS AN ISSUE AND YET REFUSES TO DO ANYTHING ABOUT IT. THERE WAS A MACHINING ERROR WITH THESE HEADS AND THE ENGINES CAN DROP A VALVE WITHOUT WARNING OR SYMPTOMS AND WITHOUT PULLING YOUR MOTOR APART THERE IS NO WAY TO DETERMINE IF YOUR CAR IS AFFECTED OR NOT. THE FACT IS NOW THAT AN INCREASING PERCENTAGE OF THESE CARS ARE LOSING THEIR ENGINES AND REPLACEMENT COST IS OVER 17000.00. SHOULD THE ENGINE GO IT COULD LEAD TO A SERIOUS CRASH FROM THE ROD PUNCTURING THE BLOCK AND SPREADING OIL UNDER AND AROUND THE CAR WHICH NOT ONLY AFFECTS THE CAR IN QUESTION BUT ANY OTHERS FOLLOWING IT AT HIGHWAY SPEED. THERE HAVE BEEN SOME THAT HAVE GONE OFF THE ROAD BECAUSE OF THIS ISSUE AND IT IS TAKING ANY OF THE JOY OF OWNING OR DRIVING THIS CAR AT ALL. GM WILL NOT EVEN TELL ANYONE OUT OF WARRANTY WHAT TO DO TO ADDRESS THE PROBLEM AND WHEN SOME HEADS WERE REPLACED BY GM FOR CARS UNDER WARRANTY, SOME WERE FOUND TO HAVE BAD TOLERANCES BEFORE EVEN BEING INSTALLED. GM HAS NOW GONE ON TO THEIR NEW MODEL Z06 AND IS SIMPLY HOPING THIS ISSUE GOES AWAY WHILE THROWING ALL THEIR LOYAL CUSTOMERS UNDER THE BUS SO TO SPEAK. SOMETHING SHOULD BE DONE BEFORE THERE IS A DEATH CAUSE FROM THIS ISSUE, NOT TO MENTION A LOYAL CUSTOMER LOSING A 17000. ENGINE THROUGH NO FAULT OF THEIR OWN. I HAVE CONTACT CHEVROLET SEVERAL TIMES AND WAS MET WITH LITTLE RESPONSE OR ENTHUSIASM TO DO ANYTHING ABOUT THE PROBLEM AT ALL.

STEERING, SUSPENSION
THERE ARE ALREADY A FEW REPORTS ON THE SKIPPING AND HOPPING AT LOW SPEEDS WHEN THE WHEELS ARE LOCKED ALL THE WAY LEFT OR RIGHT WHILE TURNING. I EXPERIENCED THIS ON DELIVERY AND HAVE OWNED THE CAR FOR 9 MONTHS. SINCE THE COLD WEATHER HAS ARRIVED THE ISSUE HAS GOTTEN EVEN MORE SEVERE, LIKE THE FRONT END IS GOING TO FALL OFF. CHEVROLET WILL NOT ADMIT TO THIS PROBLEM/ISSUE BUT IT IS A GENERALLY KNOW ISSUE RELATED TO THE "ACKERMAN" EFFECT. MOTORTREND IDENTIFIED IT AND RESORTED TO SAYING THE 2014 CORVETTE IS NO PARKING LOT CAR. CHEVROLET STILL HAS NO COMMENT. HAD I KNOWN ABOUT THIS I PERSONALLY WOULD NOT HAVE BOUGHT THE VEHICLE. IN MY OPINION CHEVROLET HAS A FIDUCIARY RESPONSIBILITY TO MAKE THE BUYER AWARE. ALSO, IF YOU SEE SOME OF THE BLOGS ON CORVETTES IT IS ALSO ACKNOWLEDGED THERE. I HAVE BEEN TO THE DEALER ABOUT IT AND THEY ARE CLUELESS. THEY GAVE ME AN EXPLANATION THAT DIDN'T HOLD WATER TO ME AND THEY EVEN DROVE THE CAR AND DUPLICATED THE MOVEMENT. I HAVE NOW ASKED FOR A FACE TO FACE WITH THE FACTORY REP. *TR

I AM SMELLING GAS FUMES COMING FROM THE DRIVER SIDE AFTER DRIVING. I CAN HEAR FUEL DRIPPING ON THE EXHAUST WHEN I PARK THE CAR IN MY DRIVEWAY WHICH IS ON AN SLIGHT INCLINE. IF IT IS NOT DRIPPING ON THE EXHAUST IT'S DRIPPING ON SOMETHING HOT BECAUSE IT MAKES A SIZZLING SOUND. PLEASE HELP! SHOULD HAVE A RECALL ABOUT THIS PROBLEM IN MY OPINION. LOTS OF CORVETTE OWNERS ARE DEALING WITH THIS SAME ISSUE. *TR

EQUIPMENT ADAPTIVE/MOBILITY, POWER TRAIN
MY GM SERVICE REQUEST NUMBERB IS:[XXX].THE AUTOMATIC GEAR SELECTOR LEVER OCCASIONALLY GOT STUCK IN PARK (P) AND TOOK A LONG DANGEROUS TIME TO GET IT WORKED LOOSE AND FUNCTIONING PROPERLY. I LIVED WITH IT FOR SEVERAL MONTHS, BUT IT GOT PROGRESSIVELY MUCH WORSE AND MORE DANGEROUS. I SPOKE TO OTHER CORVETTE OWNERS AND FOUND OUT THAT I HAD A COMMON SAFETY PROBLEM FOR MY MODEL. I FINALLY TOOK THE CAR TO THE DEALER THAT SOLD IT TO ME (MOUNTAIN VIEW CHEVROLET) WHO SAID THEY HAD SEEN A LOT OF THIS DEFECT AND THEY THEN CHARGED ME NEARLY $600 TO CORRECT THIS DANGEROUS DEFECT. NOT RIGHT!!!! IT SHOULD HAVE BEEN RECALLED FROM THE GET-GO AND FIXED PROMPTLY WITHOUT CHARGE. UNABLE TO MOVE IN TRAFFIC, GET OUT OF THE WAY OF DANGER, OR OFF OF RAILWAY TRACKS IS A POTENTIAL KILLER. THERE SHOULD BE A SAFETY RECALL. *TR

FUEL SYSTEM, GASOLINE
I PURCHASED THIS VEHICLE THIS FALL WITH ABOUT 12500 MILES ON THE ODOMETER. STARTING SHORTLY AFTER PURCHASE I WOULD OFTEN NOTICE THE SMELL OF GASOLINE IN MY GARAGE. AFTER INSPECTION, NONE OF MY OTHER VEHICLES ARE LEAKING FUEL. AFTER SEARCHING FOR A LEAK, I TURNED TO CORVETTE FORUM, WHICH HAS A DISCUSSION ON FUEL LEAKS IN THE 2008 MODEL YEAR CORVETTE. EVIDENTLY WHEN THE GAS TANK IS 3/4 OR MORE FILLED WITH FUEL, THERE IS A LEAK WHICH DEPOSITS RAW GAS ON THE TOP OF THE GAS TANK, FROM WHICH IT DRIPS OR EVAPORATES. I CONSIDER THIS LEAK A FIRE HAZARD, AND URGE NHTSA TO REQUIRE A RECALL TO FIX THE PROBLEM. THANK YOU FOR YOUR PROMPT ATTENTION TO MY REQUEST. *TR

FUEL SYSTEM, GASOLINE
IT IS A VERY WELL DOCUMENTED OCCURRENCE ON C6 CORVETTES THAT ON MANY CARS, WHEN THE TANK IS FULL, FUEL LEAKS OUT ON TOP OF THE FUEL TANK. THIS HAPPENS WHEN THE CROSSOVER PIPE BETWEEN THE TWO TANKS BEGINS TO LEAK. YOU WILL NOT FIND ANY FUEL ON THE GROUND, BECAUSE IT SITS ON TOP OF THE TANK. WHEN YOU BEGIN DRIVING IT WILL FALL OFF ONTO THE EXHAUST PIPE AND BURN OFF. THIS IS A HUGE SAFETY HAZARD, AT ANY TIME IT COULD CATCH FIRE AND LEAD TO INJURY AND/OR DEATH. THERE HAVE BEEN NUMEROUS THREADS ON CORVETTEFORUM.COM REGARDING THE ISSUE AND NOTHING HAS BEEN DONE. THIS AFFECTS MANY CORVETTE OWNERS, MYSELF INCLUDED. THE FUEL SMELL WHEN I WALK INTO THE GARAGE IS EXTREMELY POTENT, IT EVEN BEGINS ENTERING MY HOME! THE VAPOR CAN CAUSE A FIRE IN THE GARAGE, BEING A WATER HEATER IS PRESENT, AND CAUSE SEVERE PROPERTY DAMAGE. THIS IS A HUGE ETHICAL CASE FOR CHEVROLET; WELL DOCUMENTED SAFETY DEFECT, AND NOTHING HAS BEEN DONE ABOUT THIS! NOTHING THE OWNERS HAVE DONE TO CAUSE THE ISSUE, A DEFECT IN THE DESIGN AND/OR MANUFACTURING IS TO BLAME. SOMEONE COULD DIE FROM THIS SAFETY ISSUE, SOMETHING MUST BE DONE! *TR

I SMELLED GASOLINE IN THE CABIN OF MY 2008 CHEVROLET CORVETTE COUPE BASE MODEL. I TOOK IT TO LONESTAR CHEVROLET TO CHECK OUT THE PROBLEM. THEY KEPT IT OVERNIGHT AND REPORTED NOT TO BE ABLE TO SMELL WHAT I SMELLED. THEY REPORTED TO HAVE DONE A "SMOKE TEST" AND CHECK ALL CONNECTIONS BUT WAS UNABLE TO FIND ANY PROBLEM. I HAVE NOT SMELLED IT AS MUCH SINCE BUT VERY FAINTLY A COUPLE OF TIMES. *TR
