2007 DODGE DURANGO 4X4 Engine And Engine Cooling Problems

BROUGHT TRUCK IN FOR ENGINE LIGHT ON & NO POWER ON MARCH 9, 2013...CLAIMED SPARK PLUGS PUT IN BY MANUFACTURER WERE 30,000 MILES PLUGS....WHO DOES THAT ANYMORE. WHILE DOING THE TUNE UP, MECHANIC NOTICED FLUID DRIPPING. POWER STEERING PUMP WAS LEAKING. PUT NEW PUMP IN (MARCH 12, 2013) WHICH SEEMED TO BE BAD. ORDERED ANOTHER PUMP (ARRIVED MARCH 15, 2013) WHICH WORKED BUT THE RACK IN PINION STEERING BLEW SEALS ON BOTH ENDS. ORDERED PART WHICH TOOK SEVERAL DAYS TO COME IN (HOPEFULLY MARCH 20, 2013). THE MECHANIC BELIEVES THE RACK IN PINION WAS NOT RIGHT FROM THE BEGINNING. THIS WOULD ACCOUNT FOR THE FRONT TIRES WEARING QUICKLY & FUNNY. IT WOULD ALSO ACCOUNT FOR THE NOISE HEARD ON THE PASSENGER SIDE FRONT END WHEN HITTING BUMPS. BOTH THESE ISSUES WERE BROUGHT TO THE DEALERSHIPS ATTENTION PRIOR BUT NOTHING WAS DONE. CLAIMED THEY DIDN'T HEAR THE SOUND WHEN TEST DRIVING....

I HAVE A 2007 DODGE DURANGO LIMITED THAT I PURCHASED NEW 07/28/07FROM KARI DODGE CHRYSLER JEEP, 1177 US HWY 2 E, KALISPELL, MT 59901. IT IS STILL UNDER WARRANTY; THIS WILL EXPIRE 07/28/10. SINCE ABOUT MARCH 1ST, 2010 IT HAS BEEN STALLING AND LUNGING AT LOW SPEEDS; WHICH MY HUSBAND AND I THOUGHT WAS CONDENSATION IN THE GAS LINE, BUT IT FINALLY DIED ON THE ONCOMING LANE OF TRAFFIC 03/16/10. SO I CALL KARI DODGE 03/17/10 AND REPORTED THE PROBLEM. I BROUGHT IT INTO KARI DODGE 03/18/10 AND THEY CLAIM THE FIXED THE PROBLEM, SO I PICKED IT UP AND DROVE IT THROUGH THE WEEKEND. ON 03/22/10 I CALLED KARI AGAIN AND REPORTED TO THEM THE DURANGO IS STILL STALLING/HESITATING/LUNGING. I BROUGHT IT IN AGAIN 03/23/10 AND BY THE TIME I GOT TO WORK AND KARI 17 MILES LATER I WAS JUST SHAKING AND SICK TO MY STOMACH. SO FAR...
