2006 CHEVROLET CORVETTE Z06 Complaints

THE FRONT LIGHTS OF THE CAR ONE OF THEM ISN'T WORKING. I BELIEVE THIS ISN'T THE FIRST COMPLAIN ABOUT THIS KIND OF CAR. IT IS DANGEROUS TO BE DRIVING ON THE ROAD. I HAVE TO CONTINUE TO PUT MY HIGH BEAMS ON FOR THEM TO WORK. AT TIMES BOTH THE LIGHTS ARE ON AND WITH TIME DRIVING IT WILL TURN ONE OF THEM OFF. IT'S DANGEROUS BECAUSE THE VISIBILITY ON THE ROAD FOR ME AND OTHER DRIVERS.

VALVE RATTLE, NOT DRIVING VEHICLE TO KEEP FROM DROPPING VALVE......COSTS $4K FOR REPAIR TO HEADS....31000 MILES... IF I DRIVE IT AND DROP VALVE, WILL COST $18K TO REPLACE ENGINE ASSEMBLY.....LONG TERM VALUE OF VEHICLE DECREASES WITH NON-MATCHING NUMBERS VEHICLE. ONE HELLUVA WAY TO TREAT CUSTOMERS THAT SPEND $85K ON A VEHICLE.

I NEVER RECEIVED ANY NOTICE FROM GM, BUT I BROUGHT IT TO THE DEALER'S ATTENTION WHILE I WAS IN FOR A RECALL REPAIR IN 2008. I TOLD THE TECH THAT MY TRACTION CONTROL, ACTIVE STABILITY CONTROL, WASN'T WORKING PROPERLY. WHEN I RECEIVED THE CAR BACK THE TECH SAID THE TRACTION CONTROL IS FIXED AND WORKING FINE. I DIDN'T SEE HOW HE COULD HAVE SAID THAT WHEN THE CAR NEVER LEFT THE SHOP. I REALIZE NOW THAT HE WAS AWARE OF SOMETHING THAT I WASN'T. THE TRACTION WASN'T FIXED, BUT I FELT THAT I CAN'T BRING IT BACK DUE TO INCOMPETENCE. I WENT TO FORUMS AND FOUND PLENTY OF COMPLAINTS FROM OTHERS. THEN I NOTICED THAT 2005-2006 CORVETTES WITH THE RPON37 STEERING COLUMN BUILT IN 2005 WERE RECALLED FOR THIS. NHTSA CAMPAIGN NUMBER WAS 10V172000 AND GM'S CAMPAIGN # WAS N100118. I CALLED GM THEY SAID I AM MISTAKEN MY CAR IS NOT AFFECTED WHICH IS [XXX]. I THEN FOUND FROM THE INTERNET THAT PART #19179794, CLIP, WAS USED TO FIX THE ISSUE. I THEN ORDERED ONE OF THESE AND FOLLOWED THE INSTRUCTIONS TO REPAIR IT AND FOUND THIS CLIP WAS INSTALLED, BUT IMPROPERLY HENCE THE REASON IT WASN'T FIXED BY THE TECH, BUT HE WAS UNDER THE IMPRESSION IT WAS SOLVED. I THEN REPLACED THE CLIP PROPERLY AND NOW IT'S OK. GM WAS VERY DIFFICULT AND DISMISSIVE DURING THE ENTIRE ORDEAL. LOOKING ON YOUR WEB SITE IT SPECIFICALLY STATES THAT MY VIN # DOES IN FACT FALL INTO THE SPECS OF YOUR RECALL. I AM GOING TO ENCLOSE A PHOTO OF THE BENT, IMPROPERLY, INSTALLED CLIP AND A PROPER PICTURE OF THE CLIP. ALSO THE HARNESS THAT NEEDS THE CLIP TO SHOW THAT THE BENT PRONG IS NEEDED TO REPAIR THE HARNESS.

I RECENTLY HAD MY VALVES TESTED BY A LOCAL SHOP SINCE IVE HEARD FROM OTHER OWNERS THAT THE LS7 VALVES DROP AT ANY GIVEN TIME. I HAD TWO VALVES OUT OF SPECS AND HAVE TO GET IT FIXED IN ORDER TO SAVE ENGINE FROM FUTURE DAMAGE. MY CAR CURRENTLY HAS 52,241 MILES.

I HAD A FRIEND WHO HAD AN ENGINE FAILURE ON THIS SAME ENGINE DUE TO A FAILED EXHAUST VALVE. THE VALVE GUIDES WERE EXTREMELY WORN ON HIS CAR CAUSING THE VALVE FAILURE. DUE TO HIS FAILURE AND MANY OTHERS LIKE IT, I REMOVED MY HEADS AND INSPECTED. SURE ENOUGH, THEY WERE SIGNIFICANTLY BEYOND GENERAL MOTORS PUBLISHED TOLERANCES AND REQUIRED MACHINING TO REPAIR. THIS WAS AT SIGNIFICANT COST TO ME AND OUT OF POCKET. GM KNOWS OF THIS ISSUE AND REFUSES TO PARTICIPATE IN REPAIR COSTS FOR CARS OUT OF WARRANTY EVEN THOUGH IT'S A DESIGN FLAW AND SAFETY CONCERN. IF AND WHEN THE VALVE CATASTROPHICALLY FAILS, THE ENGINE WILL HAVE A COMPLETE SHUT DOWN, LARGE AMOUNTS OF SMOKE OUT THE EXHAUST CLOUDING THE OTHER DRIVERS VISION, AND HAS THE POSSIBILITY OF LEAVING OIL SLICKS ON THE ROAD SURFACE. *TR

I WAS INTERNING THE INTERSTATE 15 IN CALIFORNIA AND WAS PICKING UP SPEED TO INTER THE HWY AND MY CORVETTE Z06 STARTING MAKING A KNOCKING SOUND AND LOST POWER AND I TURNED IT OFF AND HAD IT LOOKED AT MY A VERY WELL KNOW AUTOMOTIVE SHOP WHO SPECIALIZES IN GM VEHICLES. THEY TOLD ME IT DROP AN EXHAUST VALVE.

I WAS CONCERNED ABOUT A NOISE THAT I WAS HEARING IN MY 2006 Z06 THAT IS UNLIKE ANY OTHER NOISE I HAVE HEARD WHILE CURRENTLY OWNING MY THREE OTHER GM VEHICLES. I DECIDED TO BRING IT TO A WELL KNOW CORVETTE SPECIALITY SHOP NEAR ME. THE TOLD ME ABOUT THE VALVE GUIDE ISSUE THAT HAS BEEN LINKED TO THE LS7 HEADS. I IMMEDIATELY TOLD HIM TO TAKE THE HEADS OFF THE CAR AND CHECK THEM. I HAD 4 EXHAUST VALVES THAT WERE WAY OUT OF GM SPECS. I HAD THE HEADS RE-MACHINED PROPERLY AND INSTALLED NEW INTAKE AND EXHAUST VALVE GUIDES, VALVE SPRINGS AND SEALS.

AIRBAG DISABLED LIGHT COMES ON UNDER NORMAL DRIVING CONDITIONS. SOMETIMES GOES OUT AFTER RESTART.

DRIVING ON THE FREEWAY AT APPROX. 65 MPH. , THE STEERING WHEEL ON MY CAR " TOOK CONTROL OF ITSELF AND JERKED TO THE LEFT: ON THE DASH POD IT STATED " SERVICE ACTIVE HANDLING SYSTEM" . I PULLED THE CAR OVER AS SOON AS I COULD DO SO SAFELY AND SHUT THE CAR OFF. AFTER RESTARTING IT THE WARNING WENT AWAY AND THE STEERING RETURNED TO NORMAL.
