SOON AFTER BUYING MY 2011 GMC TERRAIN, 4 CYL, A RATTLE DEVELOPED IN ENGINE ON START UP. AFTER MONTHS OF RETURNING TO DEALER, THEY SAID A TECH BULLETIN NOW EXISTED AND FIXED PROBLEM. PROBLEM WAS SOLVED, A MONTH OR SO LATER, PROBLEM RETURNED. I RETURNED TO DEALER AND THEY SAID NOTHING THEY COULD DO. AT THE SAME TIME I WAS COMPLAINING ABOUT GAS MILEAGE, 20 MPG ON HIGHWAY, 17 CITY. I CALLED GM CUSTOMER SATISFACTION DETROIT, AND HAD MANY DISCUSSIONS WITH THEM. FINALLY TOLD ME DON'T BOTHER US ANY MORE ABOUT TWO PROBLEMS, AND TO THIS POINT NO RESOLUTION TO EITHER PROBLEM. *JS

VEHICLE SPEED CONTROL
WAS DRIVING DOWN THE ROAD DOING SPEED LIMIT OF 40 MPH. ALL OF A SUDDEN THE CAR STARTED SHAKING AND BY IT SELF DROPPED TO 20 MPH. DROVE TO APT AND SHUT CAR OFF. WHEN STARTED BACK UP IT SEEMED OK. TOOK TO THE DEALER, THEY SAID IT WAS THE THROTTLE BODY AND STABILIZERS. WHICH THOSE LIGHTS CAME ON AS IT HAPPENED. ENGINE POWER CONTROL LIGHT ALSO CAME ON. DEALER SAID THEY HAD TO ORDER PARTS AND WOULD COST AROUND $600. WOW. SEEMS LIKE A LOT OF THE SAME ISSUES ON HERE. I BELIEVE THEY SHOULD PUT A RECALL ON THIS ISSUE. *TR
