NHTSA Complaint #10664868 — 2008 BUICK ENCLAVE

CHECK ENGINE/EMISSIONS CONTROL LIGHT CAME ON AS WE WERE DRIVING. STOPPED ABOUT A HALF HOUR LATER TO PUT GAS IN, AS WE WERE STOPPED AT A STOP LIGHT THE CAR DIDN'T WANT TO GO (NO POWER, NO SHIFT). AS WE WERE LEAVING THE STATION, THE CAR WOULD NOT GO. IT WOULD NOT SHIFT INTO 3RD YEAR, RPMS WERE AT 4000 AT ONLY 40MPH. DROVE HOME AND LATER DROVE IT TO THE MECHANIC. DROVE FINE THEN, BUT THE RPM GAUGE WAS FLUCTUATING. MECHANIC READ THE CODES AS 716 AND 717. TOOK IT TO A TRANSMISSION SPECIALIST AND IT DID THE SAME THING, WOULDN'T SHIFT. TRANS MECHANIC STATES ITS THE CLUTCH WAVE PLATE THAT PROBABLY BROKE AND MAGNETIC PIECES ATTACHED TO THE SENSOR CAUSING IT TO GO INTO A LIMP MODE. APPROXIMATE COST TO REPLACE THE $20 PART (WAVE PLATE) WILL BE IN THE UPPER $2000! RIDICULOUS. I'M LOSING MY FAITH IN GM VEHICLES. PER A WEB SEARCH, THIS IS A COMMON PROBLEM WITH ENCLAVE, ACADIA, OUTLOOK AND TRAVERSE. SOMETHING NEEDS TO BE DONE ABOUT THIS! *TR
