ENGINE LIGHT GOES ON AND GOES INTO DEFERRED ENGINE POWER. HAVE REPLACED THROTTLE BODY TWICE. CAR RUN GREAT AND THEN THE ENGINE LIGHT WILL GO ON AND WHEN I START THE CAR IT STARTS TO VIOLENTLY VIBRATE. I TURN OFF. SIT FOR ABOUT 10 MINUTES AND THEN TRY TO START AGAIN. SOMETIMES IT WORKS AND SOMETIMES NOT. DEFERRED ENGINE POWER IS DANGEROUS. SENSORS HAVE BEEN RESET. THIS IS AN ONGOING PROBLEM BEEN TO THE DEALER AND THEY ARE PRICE GOUGING. PROBLEM HAS BEEN GOING ON FOR SEVERAL MONTHS.

TL* THE CONTACT OWNS A 2007 CHEVROLET CORVETTE. WHILE DRIVING VARIOUS SPEEDS, THE TRACTION CONTROL SYSTEM WARNING INDICATOR AND OTHER WARNING INDICATORS ON THE INSTRUMENT PANEL FLASHED. THE VEHICLE LOST POWER AND DECELERATED. THE FAILURE WOULD CORRECT ITSELF AFTER SEVERAL MINUTES AND THE VEHICLE WOULD OPERATE NORMALLY. THE VEHICLE WAS TAKEN TO ROYAL CHEVROLET (4502 W BROAD ST, RICHMOND, VA 23230 (804) 441-9393) WHERE IT WAS DIAGNOSED WITH A FAULTY WHEEL SPEED TRACTION DETECTOR THAT NEEDED REPLACEMENT. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND REFERRED THE CONTACT TO NHTSA. THE FAILURE MILEAGE WAS APPROXIMATELY 68,100.

STATIONARY VEHICLE GETS STUCK IN PARK. NEVER CERTAIN THAT THE VEHICLE CAN BE PUT INTO DRIVE OR REVERSE. BEHAVIOR IS RANDOM-IT CAN TAKE SEVERAL TRIES OVER MINUTES TO SHIFT OUT OF PARK. DEALER REPLACED BRAKE SWITCH-DIDN'T IMPROVE BEHAVIOR. SOMETIMES I USE THE RECOMMENDED "ACCESSORY MODE" TO SHIFT-THIS TAKES SEVERAL TRIES AS WELL & HAS FAILED AT TIMES TO GET VEHICLE INTO GEAR. BEHAVIOR STARTED IN 2016.

DEPENDING ON THE POSITION OF THE DRIVERS SEAT THE AIRBAG INDICATOR ON THE DASH WILL INDICATE THAT THE AIRBAGS ARE DISABLED. IN THE EVENT OF AN ACCIDENT IF THE AIRBAGS DID NOT DEPLOY IT COULD RESULT IN SERIOUS INJURY OR DEATH. NO EVENT HAS YET TO HAPPEN FOR MY VEHICLE, BUT I FEEL UNSAFE KNOWING THAT THE AIRBAGS HAVE A DEFECT THAT MAY RESULT IN THEM NOT BEING DEPLOYED.

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.

#1 AZDANZ06'S AVATARAZDANZ06 , 01-06-2015 11:27 AM LINK TO FILE COMPLAINT: HTTPS://WWW-ODI.NHTSA.DOT.GOV/VEHICL...NT/INDEX.XHTML I JUST FILED A COMPLAINT WITH THE NHTSA ABOUT THE OUT OF SPEC VALVE GUIDE ISSUE, I WOULD ENCOURAGE EVERYONE ELSE TO DO SO AS WELL, MAYBE JUST MAYBE IT WILL FORCE GM TO FINALLY DO A RECALL AND QC ON PARTS. HERE IS MY COMPLAINT: 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, 88% OF THE CORVETTE FORUM MEMBERS WHO HAVE HAD THEIR CYLINDER HEADS TESTED FOR EXCESSIVE VALVE GUIDE WEAR, WERE OUT OF SERVICE SPECIFICATIONS. SOURCE: HTTPS://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. #2 WHIS9'S AVATARWHIS9 , 01-06-2015 11:39 AM

TL* THE CONTACT OWNS A 2007 CHEVROLET CORVETTE. THE CONTACT STATED THAT FUEL LEAKED FROM THE FUEL TANK WHILE THE VEHICLE WAS BEING REFUELED. WHILE DRIVING VARIOUS SPEEDS, THE ODOR OF FUMES EMITTED INTO THE VEHICLE. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER STATED THAT THE EXTENDED WARRANTY HAD EXPIRED. THE APPROXIMATE FAILURE MILEAGE WAS 98,000.

TRACTION CONTROL/ACTIVE HANDLING MALFUNCTION. "SERVICE TRACTION CONTROL" & "SERVICE ACTIVE HANDLING" MESSAGES STARTED SHOWN IN DIC. FROM NUMEROUS WEB FORUMS, IT'S COMMON PROBLEM IN 2005-2008 CORVETTE. MANY DRIVERS EXPERIENCED THEIR BRAKE LOCKED UP AT HIGH SPEED. IT DIDN'T OCCUR TO MY CAR (JUST MESSAGES), BUT IT COULD POTENTIALLY FATAL ISSUE. YET, GM HASN'T ISSUES RECALL TO FIX THIS PROBLEM.

NEEDLE BEARINGS WERE FOUND IN OIL PAN. THIS IS VERY COMMON PROBLEMS IN GM VEHICLES AS DEFECTIVE UNCAGED ROCKER ARM DESIGN WHICH CAUSES ROCKER ARMS TO EASILY BREAK OFF BEARINGS. GM EVEN ISSUES A BULLETIN, BUT OWNERS HAVE TO BEAR THE COST OF DEFECTIVE FACTORY-PARTS. BROKEN NEEDLE BEARINGS COULD END UP IN ENGINE AND DESTROY ENGINE. EVEN OWNERS REPLACE BROKEN ROCKER ARMS, THEY WILL FAIL BECAUSE THEY'RE UNCAGED. TO REPAIR PERMANENTLY, OWNERS HAVE TO INSTALL CAGED ROCKER ARMS FROM NON-FACTORY PART, WHICH WILL NULLIFY WARRANTY. OWNERS ARE TRAPPED IN KEEP REPLACING ROCKER ARMS, OR INSTALL NON-DEFECTIVE NON-FACTORY CAGED ROCKER ARMS AND LOSE WARRANTY. GM SHOULD RECALL THIS PROBLEM.
