NHTSA Complaint #11113946 — 2015 CHEVROLET CORVETTE

2015 CORVETTE STINGRAY Z51 - 8 SPEED AUTOMATIC TRANSMISSION TORQUE CONVERTER. WITH ONLY 7,500 MILES ON THE CAR IT STARTED TO RUN JERKY AND RPMS WOULD FLUCTUATE FOR NO REASON (ESPECIALLY AT HIGHWAY SPEEDS WHEN FULLY WARMED UP). OFTEN FELT LIKE DRIVING ON A WASHBOARD DIRT ROAD. AFTER A COLD START, THERE WAS A DELAY AFTER SHIFTING INTO DRIVE. WHEN IT ENGAGED AFTER SEVERAL SECONDS IT WOULD DO SO VIOLENTLY, LURCHING THE CAR FORWARD SUDDENLY. DEALER DIAGNOSED FAULTY TORQUE CONVERTER AS DEFECTIVE AND A KNOWN PROBLEM WITH THESE TRANSMISSIONS. AFTER LESS THAN 2,000 MILES THE SYMPTOMS RETURNED AND THE DEALER AGAIN REPLACED THE TORQUE CONVERTER. SO NOW I'M ON MY 3RD DEFECTIVE TC. AFTER 1,700 MILES, SYMPTOMS RETURNED AGAIN! DEALER SAID THAT CHEVROLET AND GM HAVE ORDERED A STOP ON REPLACING THE TC'S SINCE NO FIX WAS AVAILABLE. GM ADVISED TO DRAIN AND FLUSH TRANNY, REFILLING WITH MOBIL1 TRANSMISSION FLUID. THIS SEEMED TO WORK (ONLY FOR A LITTLE LONGER) BUT IS WORRISOME BECAUSE IN THE FUTURE SERVICE, A TECHNICIAN WILL LIKELY REFILL WITH GM FLUID, NOT MOBIL1. ESPECIALLY IF A SECOND OWNER. NOW AT 16,100 MILES THE SYMPTOMS ARE RETURNING! JERKINESS, SLAMMING INTO GEAR AFTER A DELAY ON COLD STARTS. GM SEEMS TO HAVE TURNED THEIR BACK ON STINGRAY OWNERS BY KICKING THE CAN DOWN THE ROAD BEYOND WARRANTEE (WITH THE MOBIL1 "BAND-AID FIX"). ON THE FORUMS THERE ARE SO MANY OWNER COMPLAINING ABOUT THIS SAME ISSUE. I AM AMAZED THAT THERE IS NO OFFICIAL INVESTIGATION RESULTING IN A RECALL. THIS Z51 LT3 STINGRAY WAS $75,000 OTD! FOR THIS COST WE SHOULD BE ABLE TO EXPECT A QUALITY VEHICLE AND A MOTOR COMPANY THAT STANDS BEHIND IT! CAN SOMEBODY PLEASE HELP US WITH THIS SERIOUS AND POTENTIALLY DANGERIOUS PROBLEM?
