NHTSA Complaint #11329547 — 2009 CHEVROLET CORVETTE

THIS IS HAPPENING INTERMITTENTLY, BUT FREQUENTLY: AUTOMATIC TRANSMISSION SHIFTER STAYS LOCKED IN PARK, DESPITE ENGINE RUNNING AND FOOT FIRMLY ON THE BRAKE PEDAL. CAN'T SHIFT OUT OF PARK. THIS HAPPENS WHEN CAR IS PARKED, STARTING IT UP AND TRYING TO SHIFT INTO REVERSE OR DRIVE. THE PROBLEM HAS SOMETHING TO DO WITH THE ELECTRONIC/MECHANICAL INTERLOCK OF THE AUTOMATIC TRANSMISSION. THERE IS AN ELECTRONIC SWITCH OR SOLENOID THAT IS MALFUNCTIONING, THE PREVENTS THE MECHANICAL TRANSMISSION LOCK FROM DISENGAGING. TO WORKAROUND THE PROBLEM, YOU CAN TRY TO: - TURN THE CAR OFF, AND RESTART IT. AFTER MULTIPLE TRIES, IF YOU ARE LUCKY THE TRANSMISSION INTERLOCK MAY RELEASE SUCCESSFULLY. - THERE IS AN EMERGENCY WORKAROUND PROCEDURE WHERE BY PUTTING THE CAR IN ACCESSORY MODE BEFORE STARTING IT, YOU CAN BYPASS THE INTERLOCK SYSTEM. - THE CHEVROLET DEALERS I HAVE HEARD FROM RECOMMEND REPLACING THE ENTIRE SHIFTER SYSTEM FOR $700-$1000. BUT THE NEW SHIFTERS HAVE THE VERY SAME DESIGN PROBLEM! SO NEW SHIFTERS ARE SUSCEPTIBLE TO THE SAME FAILURES IN THE FUTURE! WHEN GOOGLING THIS ISSUE ON THE INTERNET FORUMS, IT APPEARS THIS IS A WELL-KNOWN PROBLEM AFFECTING "6TH-GENERATION" CORVETTES MANUFACTURED BETWEEN 2005 AND 2013. (I HAVE A 2009 MODEL.) APPARENTLY GM HAS KNOWN ABOUT THIS PROBLEM FOR YEARS, BUT HAS NOT INVESTED IN ANY RECALL. AS A RESULT, IT APPEARS MANY OWNERS ARE CHOOSING TO DISABLE THE TRANSMISSION INTERLOCK SINCE IT IS UNRELIABLE. I WOULD LIKE TO URGE GM TO ISSUE A RECALL TO FIX THIS PROBLEM. *TR
