Consumer Description

WHEN I AM COMING FROM A STOP AND BEGINNING TO ACCELERATE AT MODERATE RATE BETWEEN 5-25 MILES MY CAR JERKS VERY HARD. THE FEELING IS SOMETIMES TO THE POINT IT FEELS AS IF I HAVE BEEN HIT FROM BEHIND BY ANOTHER CAR. THE FEELING IS VERY FORCEFUL AND IT FEELS AS IF IT BEGINS IN UNDER THE REAR SEATS AND THE REAR TIRES. IT HAPPENS SOMETIMES MAYBE ONCE OR TWICE A DAY AND OTHER TIMES EVERYTIME I PRESS THE GAS UPON COMING OUT OF A COMPLETE STOP AND SOMETIMES IT DOES THIS FORCEFUL JERK/THUMP/SHRUG CONSECUTIVELY AS I COME OUT OF THE COMPLETE STOP AND THEN AS I ACCELERATE A LITTLE MORE. HAVE TAKEN IT TO TWO CERTIFIED GM SERVICE CENTERS ON 3 OCCASIONS AND TOLD THEM THE PROBLEM. AND AFTER THE LAST VISIT THE PROBLEM HAS GOTTEN WORSE. I AM CONCERNED AS WHAT TO DO. AND THE PROBLEM IS PROGRESSIVELY GETTING WORSE. IT HAPPENS DAILY AND ON MOST OCCASIONS EVERYTIME I STOP. *TR
