Consumer Description

#5 CYLINDER ROCKER ARM BROKE TOOK TO A DEALERSHIP IN MICHIGAN TO GET REPAIRED. PROBLEMS WITH ENGINE RUNNING, BEFORE ALL THIS HAPPENED I WAS GETTING 20/22 MPG ON THE HIGHWAY WHICH IS WHAT I TRAVEL MOSTLY, NOW SINCE THIS HAPPEN I ONLY GETTING 16/18 MPG ON THE HIGHWAY. MY DEALERSHIP IN MILWAUKEE WORKED WITH AN ENGINEER FROM GM AND THEY CLAIM EVERYTHING UP TO SPEC AND WON'T DO ANYMORE ON THE VEHICLE BUT YET SOMETHING HAS HAPPENED THAT I HAVE LOST ABOUT 4/6 MPG HIGHWAY OR $20 PER TANK WHICH WITH MY TRAVELING IS A LOT OF MONEY $400 MONTH. I AM VERY DISSATISFIED WITH GM AND THIS VEHICLE RIGHT NOW WHEN YOU PAY $50,000 + FOR A VEHICLE YOU DON'T EXPECT TO HAVE PROBLEMS WITHIN THE FIRST MONTH OF PURCHASE (BRAND NEW) AND THEN FOR GM NOT TO FIND OUT WHY THE DROP IN MILEAGE IS UNACCEPTABLE. *TR
