IT STARTED RUNNING ON ITS OWN AND THE RPM'S WENT UP TO 3000 IN PARK GEAR. I TOOK IT BACK TO COLONIAL SERVICE DEPARTMENT. THEY LOOKED AT IT AND DECIDED THAT I NEEDED TO HAVE MY IAC - IDLE AIR CONTROL MOTOR REPLACED. THE NEXT DAY 4/28/11, I PICKED UP MY CAR AND DROVE IT HOME. IT SEEMED AS THOUGH EVERYTHING WAS FIXED AND WORKING FINE. UNTIL, I DROVE MY CAR ON 4/30/11. THAT IS WHEN MY CAR'S RPM WENT UP TO 3500 IN PARK GEAR. I WAS ABLE TO DRIVE MY CAR FROM SOUTH BOSTON, MA ALL THE WAY TO THE CAR DEALERSHIP IN WATERTOWN, MA WITHOUT STEPPING ON THE GAS PEDAL AT A SPEED OF 40 MPH. NOW THE DEALERSHIP IS SAYING I NEED TO REPLACE THE TPS - THROTTLE POSITION SENSOR. I AM NOT SURE THIS IS GOING TO FIX MY PROBLEM BUT I KNOW THAT I NEEDED TO REPORT THIS TO NHTSA. MOST LIKELY YOU WILL BE RECEIVED ANOTHER EMAIL FROM ME SHORTLY. THIS IS SOMETHING THAT NEEDS TO BE ADDRESS AND RESOLVED. I DO NOT WANT TO BE IN MY CAR AND HAVE AN ACCIDENT BECAUSE OF THIS PROBLEM. I DON'T WANT IT TO SEEM LIKE THIS PROBLEM WAS NEVER REPORTED TO PONTIAC OR NHTSA. THIS CAN SAVE A LOT OF PEOPLES LIVES. PLEASE HAVE SOMEONE RESEARCH THIS PROBLEM AND GET BACK TO ME. PREVIOUS EMAIL SENT TO CAC@PONTIAC.COM ON 4/24/11- DEAR SIR OR MADAM, I AM PRESENTLY HAVING A PROBLEM WITH MY 2003 PONTIAC AZTEK. WITHIN THE LAST FOUR DAYS, WHILE DRIVING MY CAR IT STARTED COASTING/DRIVING ON ITS OWN WITH ME NOT HAVING TO PRESS THE GAS PEDAL. LIKE ON 4/24/11, I WAS DRIVING AT A SPEED OF 40 MPH ON THE ROAD. I TOOK MY FOOT OFF THE GAS PEDAL AND THE CAR CONTINUED TO DRIVE BY ITS SELF AT THAT SPEED AND I WAS NOT USING THE CRUISE CONTROL. MATTER OF FACT I NEVER USE THE CRUISE CONTROL. WHEN I STOPPED THE CAR AND IT IN PARK THE RPM NEEDLE WENT BETWEEN 2000 -3000 RPMS. SURGE OR REVING MY ENGINE VERY LOUD. I BELIEVE THIS IS VERY DANGERS AND WOULD LIKE FOR YOU TO TELL ME WHAT NEEDS TO BE DONE TO FIX THIS PROBLEM. I TOOK IT TO THE COLONIAL GMC CAR DEALERSHIP IN WATERTOWN, MA ON 4/18/11 AND 4/23/11 BECAUSE THIS PROBLEM IS NOT SHOWING UP.

2003 PONTIAC AZTEK. TOOK IN DUE TO FLUID LEAKING INTO OIL AND CAUSING IT TO LOOK LIKE A "MILKY" SUBSTANCE.

2003 PONTIAC AZTEK. TOOK IN DUE TO FLUID LEAKING INTO OIL AND CAUSING IT TO LOOK LIKE A "MILKY" SUBSTANCE. TOLD THAT THESE VEHICLES ARE KNOWN FOR THIS ISSUE AND THAT THE PROBLEM WAS WITH THE INTAKE MANIFOLD GASKET. HAD THAT REPLACED (OVER $1,000) - THEN DISCOVERED STILL A LEAK - NOW THEY ARE SAYING IT PROBABLY NEEDS AN ENGINE. THE VEHICLE IS NOT EVEN 10YRS OLD. I READ ANOTHER DESCRIPTION SIMILAR TO THIS. HOW MANY INDIVIDUALS HAVE TO BE GOUGED BEFORE SOMETHING CAN BE DONE ABOUT THIS. IF THIS IS A KNOWN PROBLEM WITH THESE VEHICLES, SEEMS LIKE SOMETHING NEEDS TO BE DONE TO STOP THE MANUFACTURER FROM PREYING ON THEIR CUSTOMERS. *TR

THE ENGINE STARTED TO RUN HOT AND AFTER INVESTIGATING THE PROBLEM AT HOME WE DISCOVERED THAT THE ENGINE COOLING FANS WERE NOT WORKING. WE DID NOT FIND ANY LEAKS OR DISCONNECTED BELTS OR HOSES. WE HAVE NOT HAD A PROFESSIONAL LOOK AT IT YET BUT WE ARE VERY CERTAIN THAT THE FANS ARE NOT COMING ON. *TR

THEN WHEN IT WOULDN'T START AT ALL, HAD IT TOWED. THE GARAGE I HAD IT TOWED TO HAD BEEN THE ONE TO CHECK THE HEATER A COUPLE OF WEEKS PRIOR TO IT BREAKING DOWN, THEY HAD GIVEN IT AN OIL CHANGE ALSO. AFTER THE TOW, THEY INFORMED ME THAT ANTI-FREEZE HAD BEEN GETTING INTO THE INTAKE OIL(HEAD GASKETS),AND THEY WOULD HAVE TO TAKE IT ALL APART(LABOR!!!)---AND THAT THE FUEL PUMP WAS BAD. I'VE ONLY HAD THE VEHICLE FOR A LITTLE OVER A YEAR!!!THANK GOD I HAD A WARRANTY EXTENDED,(EVEN THOUGH I AM PAYING A LOT FOR THAT ALSO!!)THAT I ONLY(!) HAD TO PAY THE 100.00 DEDUCTIBLE, BUT THEN HAD TO PAY FOR FILTERS,OIL(AGAIN!!) AND MISCELLANEOUS OTHER EXPENSES THE WARRANTY DIDN'T PAY!!ALTOGETHER, WITH WHAT THE WARRANTY PAID, AND WHAT I PAID (341.00)---IT CAME TO 2,200.00!!!---NOW THIS CAR IS ONLY 4 YEARS OLD,BARELY!!!

SES LIGHT AND ALL DASH LIGHTS CAME ON, TOOK TO SALERNO DUANE IN NEWTON NJ WHEW I PURCHASED MY 2003 PONTIAC AZTEK NEW. WAS TOLD INTAKE MANIFOLD LEAKING AND THE CAUSE OF LIGHTS, SES AND DASH LIGHTS. $1100 LATER, LIGHTS STILL GOING OFF AND ON. NOW TOLD INSTRUMENT CLUSTER PROBLEM. $250. FOR PARTS PLUS LABOR. I AM VERY ANGRY THAT I WAS TOLD THAT IT WAS THE INTAKE MANIFOLD GASKET, THAT I PAID ALL THAT MONEY AND NOW THEY SAY IT IS SOMETHING ELSE. I ARGUED WITH THE DEALER THAT I WILL NOT PAY FOR INSTRUMENT CLUSTER OR LABOR AND THEY AGREED. I ALSO FEEL THAT I SHOULD BE REIMBURSED FOR THE INTAKE MANIFOLD GASKET AND LABOR SINCE THIS WAS OBVIOUSLY NOT THE PROBLEM IN THE FIRST PLACE AND THEY TOOK ADVANTAGE OF ME. THERE IS NO PROOF THAT THE INTAKE MANIFOLD GASKET WAS LEAKING, AND EVEN IF IT WAS, IT SHOULD BE ON A RECALL FROM GM BECAUSE IT IS A COMMON PROBLEM FOR GM MOTORS. WHEN IS ANYBODY GOING TO TAKE RESPONSIBILITY FOR THIS. *NM
