NHTSA Complaint #11203962 — 2016 CHEVROLET CORVETTE

WHILE ATTEMPTING TO ACCELERATE OR DECELERATE MY CAR I FEEL A HESITATION, FOLLOWED BY A SIGNIFICANT SHUDDER WHEN THE VEHICLE'S AUTOMATIC TRANSMISSION CHANGES GEARS. THE SHUDDER, SHAKE AND HESITATION ALSO OCCURS WHILE MY VEHICLE ACCELERATES IN A SINGLE GEAR, AND NOT ACTIVELY SHIFTING GEARS. THE PROBLEM DOES NOT MERELY RESULT IN AN UNCOMFORTABLE DRIVING CONDITION. THE SHUDDERING AND HESITATION SEEM TO BE RELATED TO INTERNAL ISSUES WITHIN THE TRANSMISSION AND/OR TORQUE CONVERTER CAUSING FRICTION SURFACES, HYDRAULIC SYSTEMS, AND GEARS TO NOT FUNCTION PROPERLY. THERE IS POSSIBLY PERMANENT DAMAGE THAT WILL OCCUR TO THE TRANSMISSION AND/OR TORQUE CONVERTER OVER TIME. I FACE ESCALATING REPAIRS THAT CAN INCLUDE FLUSHING THE TRANSMISSION OF METAL SHAVINGS CAUSED BY THE DEFECTIVE TRANSMISSION OPERATION, AND WHICH EVENTUALLY NECESSITATE THE REPLACEMENT OF COMPONENTS SUCH AS THE TORQUE CONVERTER, VALVE BODY, OR THE ENTIRE TRANSMISSION. AS SUCH, THE TRANSMISSION DEFECT ENDANGERS THE DRIVERS AND PASSENGERS OF THE VEHICLES, AND DIMINISHES THE VALUE OF THE VEHICLES. GM'S DELIBERATE NON-DISCLOSURE OF THESE DEFECTS ARTIFICIALLY INFLATED THE PURCHASE AND LEASE PRICE FOR THESE VEHICLES. GM HAS KNOWN ABOUT THE TRANSMISSION DEFECT FOR YEARS, SINCE RIGHT AFTER INTRODUCTION OF THE TRANSMISSION. SINCE 2015, GM HAS ISSUED THIRTEEN VERSIONS OF A 'TECHNICAL SERVICE BULLETIN,' OR 'TSB,' RELATED TO THIS SHIFTING ISSUE ALONE. THE TSBS RELATED TO THE TRANSMISSION ISSUE HAVE ADVISED DEALERSHIPS TO, AMONG OTHER THINGS: COMPLETE THE 'CLUTCH DRIVE LEARN PROCEDURE,' REPLACE THE VALVE BODY, REPLACE THE ENTIRE TRANSMISSION, FLUSH THE COOLER LINES AND COOLER, REMOVE DEBRIS FROM AND CLEAN THE TRANSMISSION PAN, REPLACE THE TRANSMISSION FILTER, REPLACE THE TRANSMISSION FLUID, AND FLUSH THE TRANSMISSION. TO DATE, NONE OF GM RECOMMENDED SOLUTIONS HAS RESOLVED THE PROBLEM.
