HEADLAMPS - THE HEADLAMPS HAD TO BE REPLACED DUE TO LIGHT BEAMS NOT COMING THROUGH THE CLEAR PLASTIC COVER. THE COVER BECAME CLOUDY AND VISIBILITY WAS LIMITED WHICH CAUSED SAFETY CONCERNS. THE CHRYSLER DEALERSHIP TRIED TO CLEAN BUT WAS NOT SUCCESSFUL. TIRE SENSORS - A YEAR AGO, WE HAD AN ISSUE WITH THE MESSAGE CENTER NOT RESPONDING TO THE TIRES. THE CHRYSLER DEALERSHIP INSTALLED 1 TIRE SENSOR AND SEVERAL MONTHS LATER A NEW MESSAGE CENTER PANEL HAD TO BE REPLACED. A YEAR LATER, WE ARE REPLACING THE OTHER THREE SENSORS. WE ARE TOLD BY THE CHRYSLER DEALERSHIP THAT THE BATTERIES ONLY LAST SEVERAL YEARS. THEY CLAIM THAT THESE SENSORS ARE GOVERMENT REGULATED. WHY ARE WE PUTTING PARTS INTO AMERICAN MADE CARS THAT HAVE TO BE REPLACED EVERY SEVERAL YEARS THAT COST $100 FOR EACH SENSOR PLUS LABOR. EITHER CHRYSLER NEEDS TO PRODUCE A BETTER SENSOR THAT LASTS LONGER OR THE GOVERNMENT SHOULD PROVIDE REBATES SINCE THIS IS REGULATORY. THESE CAR ISSUES SHOULD BE CONSIDERED A SAFETY ISSUE AND REVIEWED FOR POTENTIAL LIABILITIES THAT CAN CAUSE HARM TO THE DRIVER. *TR

TL* THE CONTACT OWNS A 2004 CHRYLSER PACIFICA. THE CONTACT STATED THAT THE FRONT ENGINE MOUNT CRADLE, WHICH HELD THE ENGINE IN PLACE, WAS FRACTURED.

AFTER OWNING MY 2004 CHRYSLER PACIFIA FOR 7 YEARS, I WAS TOLD BY THE DEALER, DURING A ROUTINE OILCHANGE, THAT THE SUBFRAME IS RUSTED OUT AND WOULDNT LAST MUCH LONGER. THERE ARE TWO RUST HOLES IN THE FRAME STRUCTURE ON THE LEFT SIDE AND MORE FORMING ON THE RIGHT SIDE ON THE HEIGHT OF THE WHEELS. REPLACING THE SUBFRAME (WHICH HOLDS THE MOTOR IN PLACE) WOULD COST ABOUT +$4000!! I HAVE ALWAYS TAKING EXCELLENT CARE OF THIS CAR. IT IS IN GREAT SHAPE INSIDE AND OUT - EXCEPT THE FRAME. AFTER DOING SOME RESEARCH ONLINE I HAVE FOUND THAT I AM NOT ALONE. THERE IS A MULITUDE OF 2004 CHRYSLER OWNERS HAVING THE EXACT SAME PROBLEM AS I DO. THIS ISSUE NEEDS TO BE RESOLVED BY CHRYSLER.

2004 CHRYSLER PACIFICA TAKEN TO MECHANIC AFTER PURCHASING USED WITH 69,500 MILES FOR "CLUNKING" NOISE IN FRONT-END. REPLACED PARTS INCLUDED: SWAY BAR LINKAGES, TIE ROD ENDS, AND STRUTS AND MOUNTS ALL OF WHICH NEEDED REPLACING. BUT THE NOISE WAS STILL THERE. THE MECHANIC THEN USED A TOOL HE CALLED "CHASSIS EARS" TO PINPOINT THE SOURCE OF THE NOISE. HE FOUND THAT THE SUBFRAME (ENGINE CRADLE) WAS RUSTED AT THE POINT THAT IT MOUNTS TO THE BODY, JUST UNDER THE FRONT PASSENGER-SIDE FLOORBOARD. UPON FURTHER INSPECTION RUST WAS APPARENT ON THE DRIVERS-SIDE ALSO. THIS IS A MAJOR SAFETY ISSUE!!! THE ENTIRE FRONT-END OF THE VEHICLE INCLUDING: ENGINE, TRANSMISSION, AND ALL FRONT-END SUSPENSION AND STEERING IS HELD IN PLACE BY THIS SUBFRAME (ENGINE CRADLE). WHAT HAPPENS WHEN THIS TOTALLY FAILS WHILE DRIVING WITH SIX PEOPLE IN THE VEHICLE? WHY HAS THIS NOT BECOME A MANDATORY SAFETY RECALL? DOES SOMEONE HAVE TO GET KILLED BEFORE THIS GETS SOMEONES ATTENTION? THIS IS NOT AN ISOLATED INCIDENT AS CAN BE SEEN BY THIS WEBSITE. NHTSA PLEASE HELP!!! *TR

85,000 MILES ON A WELL MAINTAINED VEHICLE. NOTICED NOISE IN CHASSIS ESPECIALLY TURNING AND OVER BUMPS.

CONTACTED CHRYSLER ONLY TO LEARN THAT "SELECT 2002 AND 2003 PACIFICA MODELS IN HIGH CORROSION AREAS" HAVE EXTENDED WARRANTY (UP TO 150,000 MILES) FOR THIS EXACT ISSUE. UNFORTUNATELY CHRYSLER WILL NOT COVER 2004 MODELS!!! VERY EXPENSIVE TO REPAIR! SAD THAT CHRYSLER WILL NOT STAND BEHIND THEIR VEHICLES.... ESPECIALLY SINCE THEY OBVIOUSLY KNOW IT'S AN ISSUE! *TR

ON FEBRUARY 27, 2006 RQ06-002 WAS OPENED IN RESPONSE TO 60 COMPLAINTS OF ENGINE STALL, MOSTLY DURING LEFT-HAND TURNS, IN MODEL YEAR (MY) 2004 TO 2006 CHRYSLER PACIFICA VEHICLES THAT WERE OUTSIDE THE SCOPE OF RECALL 04V-113.IN MARCH 2004, DAIMLERCHRYSLER INITIATED RECALL 04V-113 ON 34,561 MY 2004 PACIFICA VEHICLES TO CORRECT A CONDITION THAT COULD RESULT IN ENGINE STALL WHILE MAKING A LEFT-HAND TURN AFTER A COLD-START.DURING RQ06-002 IT WAS DETERMINED THAT RECALL 04V-113 DID CORRECT THE SPECIFIC CAUSE OF THE ENGINE STALLING CONDITION FOR THAT SPECIFIC POPULATION.HOWEVER, TWO OTHER CONDITIONS WERE IDENTIFIED THAT COULD ALSO CAUSE ENGINE STALLING DURING TURNING MANEUVERS:(1) AN ISSUE WITH MISBUILT FUEL PUMPS THAT PRIMARILY AFFECTED ABOUT 17,000 MY 2005 PACIFICA VEHICLES BUILT DURING AUGUST AND SEPTEMBER 2004; AND (2) A SOFTWARE CONDITION AFFECTING VAPOR PURGE IN ABOUT 131,000 MY 2005-06 PACIFICA VEHICLES BUILT FROM JULY 2004 THROUGH NOVEMBER 2005.

ON FEBRUARY 22, 2006, ODI OPENED PE06-009 TO INVESTIGATE REPORTS THAT THE FUEL TANKS ON MODEL YEAR (MY) 2004 TO 2005 CHRYSLER PACIFICA VEHICLES MAY BE PUNCTURED BY CONTACT WITH ROAD DEBRIS.THE NUMBER OF REPORTS SUBMITTED BY CHRYSLER WAS SIGNIFICANTLY HIGHER THAN THOSE SUBMITTED BY OTHER MANUFACTURERS WHO WERE REQUESTED TO SUBMIT DATA AS PART OF INVESTIGATION PE05-050 INTO MY 2003 TO 2006 NISSAN MURANO VEHICLES THAT MAY HAVE HAD INSUFFICIENT SHIELDING OF THE FUEL TANK TO PREVENT PUNCTURES AFTER CONTACT WITH ROAD DEBRIS.NISSAN ISSUED RECALL 06V-003 INVOLVING INCREASING THE SHIELDING OF THE FUEL TANKS TO REDUCE THE LIKELIHOOD OF TANK PUNCTURES. CHRYSLER HAS NOTED THAT THEY HAD IN PLACE FROM JANUARY 2003 TO JUNE 2005 A PARTS RESTRICTION PROGRAM ON PACIFICA FUEL TANK REPLACEMENTS WHICH MAY HAVE MADE THE NUMBER OF REPORTS ARTIFICIALLY HIGH IN COMPARISON TO MANUFACTURERS WHICH DID NOT HAVE A SIMILAR PROGRAM IN EFFECT.CHRYSLER ALSO QUESTIONED WHETHER MANY OF THE FIELD REPORTS OF FUEL TANKS REPLACED DUE TO DAMAGE FROM UNKNOWN CAUSE WERE ACTUALLY PUNCTURED. THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA06-010) TO GATHER ADDITIONAL INFORMATION CONCERNING THE ALLEGED DEFECT IN THE SUBJECT VEHICLES.
