TL* THE CONTACT OWNS A 2006 CHEVROLET CORVETTE. WHILE DRIVING AT APPROXIMATELY 60 MPH, THE PASSENGER SIDE BRAKE CALIPER ENGAGED AND THE CONTACT LOST CONTROL OF THE VEHICLE.

THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 60,000.

VEHICLE WILL NOT SHIFT TO PARK AFTER STARTING ENGINE AND ENGAGING THE BRAKE. TRIED RESTARTING AND SHIFTING THE CAR INTO REVERSE SEVERAL TIMES AND IT FINALLY WENT INTO REVERSE AFTER APPROXIMATELY 10 MINUTES OF TRYING. THE VEHICLE WAS ON A FLAT SURFACE. AFTER READING NEWS AND FORUM ARTICLES, THIS SEEMS TO BE A COMMONLY KNOWN PROBLEM, WITH THE ONLY FIX BEING TO REPLACE THE SHIFTER ASSEMBLY. GM DOES NOT HOWEVER WANT TO ADDRESS THIS. THIS SHOULD BE A RECALL ITEM.

TL* THE CONTACT OWNS A 2006 CHEVROLET CORVETTE. WHILE DRIVING AT 25 MPH, THE SERVICE ACTIVE HANDLING SYSTEM WARNING LIGHT ILLUMINATED. THE FAILURE OCCURRED ON SEVERAL OCCASIONS.

ANY QUICK SEARCH OF THE WEB WILL SHOW THAT THIS CAR ENGINE, THE LS2 OR 6.2 L ENGINE HAS HAD A DEFECT THAT GM HAS DENIED OVER THE YEARS AND FAILS TO STAND BEHIND AFTER WARRANTY; CRANK SHAFT PULLEY WOBBLE AND WORN RUBBER GASKETS ON THE HARMONIC BALANCER OF THE 2006 MODEL YEAR. TECH BULLETINS HAVE BEEN ISSUED AND THIS TOPIC OF PULLEY WOBBLE AND RUBBER GASKET FAILURE AND IS QUITE THE TALK ON VARIOUS CORVETTE FORUMS. SINCE I AM WELL BEHIND WARRANTY, I HAD TO HAVE THIS DIAGNOSED THROUGH MY LICENSED CERTIFIED AUTO MECHANIC. THIS REPAIR REQUIRES EXTENSIVE LABOR TIME TO REPAIR. SCARED TO SEE THE BILL TOMORROW. GM'S RESPONSE IS I SHOULD OF TAKEN IT TO AN AUTHORIZED CHEVY DEALER. THAT IS HOG WASH BECAUSE SHOULD I HAD DONE THAT, I WOULD PROBABLY STILL HAD TO PAY THEIR EXORBITANT LABOR COSTS AND STILL NOT BE COVERED ON THIS SERIOUS ENGINE DEFECT. IN FACT, I BELIEVE GM HAS RE-DESIGNED THE PART SO WHAT DOES THAT TELL YOU. FAILURE TO FIX WILL JUST HARM THE ENGINE FOR THE FUTURE AND REPLACE BELT AFTER BELT WHEN THE TRUE PROBLEM IS IGNORED BY GM

CRUISING AT 50 MPH ON FEEDER RAMP AND DIC SHOWED ENGINE POWER REDUCED FOR 2 SECONDS THEN BOOM! *TR

I BOUGHT THIS CORVETTE Z06 USED FROM A PRIVATE PARTY. THE ENGINE HAD A CATASTROPHIC FAILURE DUE TO A KNOWN ISSUE WITH THE VALVE GUIDES AND VALVES IN THE LS7 MOTOR FROM THE FACTORY. I WAS DRIVING HOME FROM WORK WHEN THE MOTOR FAILED. I WAS LUCKY TO BE ONLY A MILE FROM HOME WHEN IT FAILED AND I WAS ABLE TO COAST INTO MY GARAGE. THE EXHAUST VALVE DROPPED AND DESTROYED THE #1 PISTON ALONG WITH THAT CYLINDER, AND THE ENGINE BLOCK. NOTHING IN THE MOTOR IS SALVAGEABLE AS IT BENT OR SENT METAL SHARDS INTO EVERY PART OF THE MOTOR. I HAVE TRIED SEVERAL TIMES TO GET CHEVY TO HELP ME WITH THIS MOTOR, BUT THEY WILL NOT HELP AT ALL. THEY KNOW ABOUT THE PROBLEM, BUT WILL NOT LIFT A FINGER TO HELP ANYONE. *TR

TL* THE CONTACT OWNS A 2007 CHEVROLET CORVETTE EQUIPPED WITH FOUR AFTERMARKET MHT F350 NITROUS SEC WHEELS. THE CONTACT STATED THAT THE INNER WHEEL FAILED, WHICH CAUSED THE TIRES TO PUNCTURE AND BENT THE RIMS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO REPLACED THE DRIVER SIDE TIRE AND WHEEL. THE CONTACT STATED THAT FOUR TIRES FLATTENED DUE TO THE FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 58,000. THE VIN, SERIAL NUMBER, AND PART NUMBER WERE NOT AVAILABLE. UPDATED 5/28/15 *TA UPDATED 11/23/2015*JS

MANUFACTURING DEFECTED IN THE LS7 MOTOR. UPON FURTHER INVESTIGATION I HAD MY 2006 CORVETTE Z06 INSPECTED FOR A LOUD AUDIBLE TICK IN THE MOTOR. THE SOURCE OF THIS NOISE WAS FROM THE IN-BALANCE FROM THE #3 AND #4 INTAKE VALVES ON THE ENGINES HEADS. THERE IS PREMATURE WEAR ON BOTH VALVE GUIDES CAUSING INTERNAL FAILURE TO THE MOTOR. UNDER POWER DEMAND THE IN-BALANCE WILL CAUSE THE TITANIUM ROD TO STRIKE THE SIDES OF THE VALVE SEAT CAUSING THE HEAD OF THE VALVE TO CRACK AND FALL INTO THE CYLINDER. ONCE THIS OCCURS INSTANT CATASTROPHIC FAILURE OF THE MOTOR HAPPENS RESULTING IN WHITE BELLOWING SMOKE FROM THE EXHAUST, OIL SPILLAGE, AND ENGINE LOCK RESULTING IN THE VEHICLE SKIDDING OFF THE ROAD OR LOOSING CONTROL. FORTUNATELY FOR ME I CAUGHT THIS IN TIME BEFORE HAVING A CATASTROPHIC FAILURE. BOTH LS7 HEADS ARE BEING REPAIRED AND MACHINED TO MEET INDUSTRY STANDARDS. THIS PROBLEM MUST BE ADDRESSED TO ALL LS7 Z06 OWNERS AS IT COULD AND HAS CAUSED SEVERAL CRASHES AND POSSIBLE DEATHS. ONCE REPAIRS TO THE LS7 HEADS ARE MADE THE VEHICLE CAN BE RETURNED TO SERVICE. *TR

2006 Z06 CORVETTE ENGINE WAS MAKING AN UNUSUAL NOISE. AFTER DOING SOME RESEARCH AND THE FINDING, IT WAS DETERMINED THAT THE VALVETRAIN ON THE ENGINE MAY BE PENDING FAILURE. THE HEADS WERE REMOVED AND VALVE TRAIN TOLERANCE CHECKED TO BE FOUND WAY OUT OF SERVICEABLE LIMITS. THUS REQUIRING REPAIR. THIS WAS CONSIDERED EXCESSIVE WEAR FOR SUCH A LOW MILEAGE VEHICLE THAT WAS PENDING CATASTROPHIC ENGINE FAILURE IF THE REPAIRS TO THE HEADS WAS NOT PERFORMED. IN DOING ADDITIONAL RESEARCH, THIS APPEARS TO BE QUITE COMMON FOR THE Z06'S 7.0L LS7 ENGINE. LUCKILY MY ENGINE DID NOT HAVE A CATASTROPHIC FAILURE BECAUSE I TOOK PREVENTATIVE MEASURES AT MY OWN COST, BUT THIS DESIGN SHOULD BE CONSIDERED A FAILURE AND RECALLED. I WAS NOT GOING TO RISK A CATASTROPHIC ENGINE FAILURE POSSIBLY ON THE HIGHWAY AND PUT MYSELF AND OTHERS AT RISK. PLEASE INVESTIGATE.
