2002 PONTIAC FIREBIRD Engine And Engine Coolingengine Problems

I PURCHASED THE 2002 PONTIAC COLLECTORS EDITION FIREBIRD AS MY FIRST NEW CAR. I REGRET TO SAY THAT I AM VERY DISAPPOINTED IN THE PERFORMANCE AND CONSTRUCTION OF THIS VEHICLE. MY FIRST COMPLAINT IS A SEVERE VIBRATION THROUGHOUT THE VEHICLE WHEN DRIVING OVER 55 MPH OR AFTER IT WARMS UP. THIS VIBRATION IS FELT THROUGH THE SHIFTER AS WELL AS BEING APPARENT WHEN YOU STAND BEHIND THE VEHICLE NEAR THE EXHAUST WHILE IT IS RUNNING. I HAVE BEEN INFORMED FROM TWO SEPERATE DEALERSHIPS THAT THEY ACKNOWLEDGE THE PROBLEM BUT GM WILL NOT APPROVE THE REPAIR DUE TO THE MILEAGE AND THE LACK OF A COMPUTER CODE, EVEN THOUGH THE GM MECHANICS HAVE AGREED THERE IS A PROBLEM. THE CAR HAS NOW GONE OVER THE MILEAGE REQUIRMENT AND IT IS WORSE. I ALSO WAS INVOLVED IN AN ACCIDENT WITH THIS CAR DUE TO A DRUNK DRIVER DAMAGING THE DRIVER'S DOOR. WHEN...

WHILE OPERATING THE VEHICLE AT APPROXIMATELY 65 MPH THE VEHICLE EXPERIENCES A TOTAL LOSS OF POWER. WHEN THE ACCELERATOR IS PRESSED THE RPM'S ON THE VEHICLE HIT THE ROOF BUT THE ENGINE OR TRANSMISSION DO NOT RESPOND LEAVING THE VEHICLE CRUISING AT ABOUT 15 MPH ON A VERY BUSY INTERSTATE HIGHWAY I-95. THE VEHICLE HAS BEEN BROUGHT IN TO THE DEALERSHIP ON TWO SEPERATE OCASIONS FOR THE SAME PROBLEM. THE SERVICE TEAM SAYS THEY CAN NOT OR ARE NOT ABLE TO RECREATE THE LOSS OF POWER IN THE VEHICLE THEREFORE ARE NOT ABLE TO FIX IT. THIS INCIDENT HAS OCCURED THREE TIMES IN ABOUT A SIX MONTH PERIOD. THE VEHICLE IS NEW AND NO INDICATOR LIGHTS ARE ACTIVATED WHEN THIS HAPPENS.*JB
