Consumer Description

WE PURCHASED A NEW GMC ACADIA ON 6/16/08. SINCE OUR PURCHASE, WE HAVE EXPERIENCED A DANGEROUS TRANSMISSION ISSUE. AFTER COASTING DOWNHILL, THE VEHICLE FAILS TO DOWNSHIFT WHICH CAUSES A RAPID DECELERATION WHEN TRAVELING UPHILL. THIS RAPID LOSS OF SPEED PUTS THE DRIVER IN THE HAZARDOUS SITUATION OF A REAR END/CHAIN REACTION COLLISION ON THE ROAD GMC CLAIMS TO HAVE A FIX, BUT THIS FIX CAUSES THE DOCUMENTED GAS MILEAGE TO BE REDUCED BY AT LEAST 2-3 MILES PER GALLON. THEY HAVE ATTEMPTED TO FIX THIS ISSUE TWICE IN THE LAST 4 WEEKS TO NO AVAIL. *TR
