NHTSA Complaint #10554880 — 2009 GMC ACADIA

INITIALLY NOTICED WHEN SHIFTING FROM PARK TO ANOTHER GEAR SHIFTING WAS HARD. ABOUT A WEEK LATER NOTICED HESITATION IN SHIFTING GEARS WHILE DRIVING AT VARIOUS RATES OF SPEED THEN THE ENGINE WOULD REV ONCE IT SHIFTED INTO GEAR. EVENTUALLY PARKED THE CAR IN DRIVE THEN WENT TO BACK OUT TO TAKE TO DEALERSHIP AND IT WOULD NOT GO INTO REVERSE. VEHICLE TOWED TO DEALERSHIP WHERE THEY REPLACED THE WAVE PLATE AND OTHER PARTS THAT WERE CONTAMINATED. SINCE THIS INCIDENT THE VEHICLE HAS NOT DROVE SMOOTHLY OR SHIFTED GEARS SMOOTHLY. IT ALSO GETS LESS THAN 15 MILES TO THE GALLON DURING MY DAILY COMMUTE NOW WHERE PRIOR TO THE TRANSMISSION FIX I WOULD GET 19-20. VEHICLE HESITATES AND REVS CONTINUALLY WHILE DRIVING AND ACCELERATING. WHEN I RETURNED THE VEHICLE TO THE DEALERSHIP STATING THERE WAS STILL AN ISSUE I RECEIVED "WE COULD NOT REPLICATE THE ISSUE" AND SENT ON MY WAY. AFTER RESEARCH ON THIS SITE AND OTHER AND READING THE SYSTEMIC ISSUES OTHERS HAVE HAD JUST LIKE IT I AM CONCERNED FOR MY FAMILY AND THOSE AROUND ME SAFETY IF THE TRANSMISSION DECIDES TO STOP WHILE TRAVELING HIGH SPEED IN TRAFFIC OR WHEN CROSSING TRAFFIC. *TR
