2007 CHEVROLET CORVETTE Complaints

NOTED A SPONTANEOUS FUEL SMELL IN CABIN BEHIND DRIVERS SEAT AFTER RETURNING TO PARKED VEHICLE. AT FIRST ASSUMED THAT THE TANK MAY HAVE BEEN OVERFILLED. THE STRONG FUMES PERSISTED IN THE CABIN AND ALSO WHEN APPROACHING THE VEHICLE UNTIL THE FUEL TANK EMPTIED BELOW THE 1/2 MARK. BROUGHT VEHICLE TO CHEVY DEALER JUST BEFORE WARRANTY EXPIRATION. I WAS TOLD IT WAS LEAK TESTED AND THEY COULD NOT FIND ANY LEAK. I HAVE SINCE TAKEN IT TO X3 INDEPENDENT MECHANICS SPENDING OVER 600.00 AND NONE HAVE BEEN ABLE TO CORRECTLY DIAGNOSE OR CORRECT THE PROBLEM. THE FUMES ONLY OCCUR WHEN THE TANK IS FILLED JUST PAST THE 1/2 FULL MARK. I HAVE BEEN TOLD BY THE MECHANICS THAT THE TANKS WOULD NEED TO BE DROPPED TO FIND THE PROBLEM THIS WOULD BE AT A MINIMUM COST OF 1600.00$. NEEDLESS TO SAY I HAVE BEEN DRIVING MY VEHICLE 1/2 FULL FOR OVER 2YEARS NOW. OF COURSE I FEEL MY VEHICLE MAY STILL BE POTENTIALLY DANGEROUS, NOT ONLY THE EXPOSURE TO THE FUMES BUT ALSO THE RISK OF A FIRE OR EXPLOSION AND I FEEL THAT THE MANUFACTURER IS BEING NEGLIGENT BY NOT ADMITTING THERE IS A PROBLEM WITH THEIR DESIGN FLAW. FROM WHAT I UNDERSTAND IN THE CORVETTE FORUM THE DESIGN HAS BEEN CHANGED IN NEWER MODELS.

I HAVE A 2007 CORVETTE Z06 WITH 43 K MILES ON IT. I DECIDED TO HAVE SOMEONE CHECK MY CAR BECAUSE OF THE ARTICLE I HAD READ ABOUT THE LS7 ENGINES HAVING VALVE GUIDE ISSUES. I WAS SURE THAT THEY WOULD BE OK BECAUSE THE CORVETTE SITES SAY IT IS ONLY A MINOR AMOUNT OF HEADS THAT WERE MACHINED IN CORRECTLY. I WAS HAVING OTHER WORK DONE TO MY CORVETTE SO LOOKED FOR A PLACE THAT DOES MOSTLY CORVETTE SERVICE, I TOLD THE MECHANIC TO CHECK MY VALVE GUIDES WHILE HE WAS DOING THE OTHER WORK I WAS SURE THEY WOULD OF BEEN OK. UPON MY SURPRISE HE SENT ME VIDEOS SHOWING ME THAT THEY WERE NOT OK AND NEEDED TO BE REPAIRED. IT COST ME $1,950.00 TO HAVE MY HEADS CNC AND NEW VALVE GUIDES AND SPRINGS INSTALLED THE OLD ONES WERE VERY BAD I HAVE VIDEOS SHOWING THIS, THE CAR WAS RUNNING WITH LITTLE VALVE NOISE AT THE TIME BUT WERE STILL BAD MECHANIC WOULD NOT EVEN DYNO THE CAR AFTER SEEING HOW BAD THEY WERE.

THE CAR SMELLS LIKE GASOLINE AFTER I FILL IT UP PAST 1/2 A TANK. ONCE IT GETS BELOW 1/2 WAY, IT NO LONGER SMELLS

MY 2007 CORVETTE 2D CONVERTIBLE LOCKS YOU IN THE CAR. YOU COULD GET STUCK IN THE CAR AND SUFFOCATE TO DEATH. THE WINDOWS AND DOORS WILL NOT OPEN, CAR IS NOT RECOGNIZING THE FOB, YOU ARE TOTALLY STUCK. RESORT TO EMERGENCY RELEASE ON FLOOR BESIDE THE SEAT. LOTS OF PEOPLE DON'T KNOW IT'S THERE! LIKE A PASSENGER SITTING IN THE CAR WHILE YOU GO TO DO AN ERRAND. THEY COULD "BURN UP" OVERHEATED AND STUCK! GM KNOWS THAT THEY HAVE A PROBLEM AS THEY SENT ME A LETTER ADVISING ME ABOUT THE EMERGENCY RELEASE! BUT THEY REFUSE TO FIX IT CLAIMING THEY DON'T HAVE A PROBLEM!. ...UPDATED 02/23/16 *BF

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/...-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.

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.

MY C6 2007 CHEVROLET CORVETTE HAS A VERY STRONG FUEL SMELL INDICATING IT HAS ONE OR MANY FUEL LEAKS WHICH IS A LARGE DANGER AND AN EMISSIONS VIOLATION. THIS IS A VERY WIDELY-KNOWN ISSUE WITH A LARGE NUMBER OF C6 OWNERS BUT GM WILL NOT INITIATE A RECALL ON THE FAULTY FUEL PUMP OR LEAKING SEALS ON THE GAS TANKS. THIS NEEDS TO BE ADDRESSED ASAP BEFORE SOMEONE GETS KILLED.

GAS GAGE STOPPED WORKING DUE TO FOULTY GAS TANK GAGE IN SECOND GAS TANK. THIS CAR HAS TWO GAS TANK WITH TWO GAS TANK GAGE WHICH NUMBER TWO GAS GAGE IT STOPS WORKING AND DOES NOT SHOW

STRONG FUEL SMELL BOTH INSIDE AND OUTSIDE THE CAR WHEN THE GAS TANK IS OVER HALF FULL. IT APPEARS TO COME FROM THE LEFT SIDE AT THE FUEL TANK AREA. THERE IS NO VISIBLE LEAK UNDER THE CAR. THE CAR HAS 17980 MILES PRESENTLY.
