I AM ALMOST VERBATIM SUBMITTING AN IDENTICAL COMPLAINT THAT YOU RECEIVED A DAY AFTER I WAS SHOWN THE EXACT SAME PROBLEM, AFTER TAKING MY CHRYSLER PACIFICA IN FOR A ROUTINE OIL CHANGE. THIS IS EXACTLY WHAT I WAS TOLD TOO ON MARCH 28, 2014. I WAS TOLD I HAVE A SUBFRAME/ENGINE CRADLE THAT IS SEVERELY CRACKED AND CORRODED ON THE PASSENGER SIDE OF THE VEHICLE AND SHOWING WEAR ON THE DRIVER SIDE. I WAS NOT INFORMED OF THIS SERIOUS SAFETY ISSUE WITH MY VEHICLE. I HAVE SUBMITTED AN EMAIL TO CHRYSLER AND AM WAITING THEIR RESPONSE BUT UNDERSTAND THAT CUSTOMERS ARE MOST OFTEN TOLD THERE IS NOTHING THEY CAN DO TO ASSIST WITH THE NEARLY $3000 COST OF REPLACEMENT, BECAUSE THE VEHICLE WAS NOT MADE IN THE NARROW WINDOW OF PRODUCTION THAT THEY CLAIM WAS AFFECTED AND SUBJECT TO RECALL. AND MAY I ECHO THE ENTIRE LAST COMPLAINT THAT WAS SUBMITTED THAT I JUST READ BECAUSE IT'S EXACTLY HOW I FEEL TOO. I HAVE READ THAT CHRYSLER ALSO SELECTIVELY DECIDES WHO TO HELP WITH THE COST OF REPAIRS, REGARDLESS OF THEIR RECALL WINDOW AND WARRANTY, AFTER THE CUSTOMER MAKES ENOUGH NOISE. IF IT IS NOT THEIR FAULT, WHY ARE THEY DOING THAT? THE NBC REPORT ALSO INDICATES THAT NHTSA SEES NO PATTERN WITH THE NUMEROUS CLAIMS YOU HAVE RECEIVED OUTSIDE OF THE SUPPOSED RECALL WINDOW, LIKE THIS ONE, HOW MANY PEOPLE HAVE TO BE PUT AT GRAVE RISK BEFORE YOU SEE A PATTERN? YOU MIGHT SEE A PATTERN IF MORE PEOPLE KNEW THEY ARE DRIVING UNSAFE PACIFICAS, SO THAT THEY COULD REPORT IT. PLEASE RECONSIDER YOUR RECALL DECISION, AS CHRYSLER'S LIABILITY IS CERTAINLY MORE THAN A COUPLE MONTHS OF PRODUCTION. " *TR

HAVE A 2004 CHRYSLER PACIFICA I'VE HAD THIS TRUCK FOR TWO YEARS, I'VE ALWAYS HAD A PROBLEM WITH THE GAS RUNNING OUT LIKE WATER. I TOOK MY TRUCK TO CHRYSLER FOR THEM TO DO A TUNE UP, WHILE THERE I TOLD THEM ABOUT THE PROBLEM. WHEN I GOT BACK TO PICK UPMY TRUCK THEY TOLD ME THAT BOTH OF MY FUEL PUMPS WERE BAD. IT SEEMS LIKE THEY KNOW WHAT'S WRONG WITH THESE TRUCKS AND THEY JUST DECIDED TO TELL EVERYONE THEIR FUEL PUMPS ARE BAD. ANYWAY, I HAD THE FUEL PUMPS CHANGED AND THE PROBLEM GOT WORSE. NOW IF I PUT $10 IN IT THE GAUGE WILL READ 1/2 TANK. IF I FILL IT UP ONCE IT GETS TO 1/2 TANK IT'LL JUST DROP TO THE E. ONCE IT READS E IT CUTS OFF. THERE COULD BE A FULL TANK OF GAS BUT IT WILL STILL READ E. I TOOK IT BACK TO CHRYSLER SO MANY TIMES THEY COULDN'T FIND ANYTHING WRONG. THE LAST TIME I WENT BACK UP THERE, THEY SAID I NEED TO REPLACETHE WHOLE TANK. I KNOW FOR A FACT THAT REPLACING THE TANK WON'T FIX IT. TO ADD TO THAT, WHILE I'M PUMPING GAS THE GAS FOAMS OR IT KICKS BACK. I REFUSE TO KEEP PAYING MY MONEY FOR THEM TO KEEP PLAYING THE GUESSING GAME. IF MY TRUCK SHUTS DOWN COMPLETELY OR CAUSE AN ACCIDENT I'M SUING CHRYSLER AND EVERYONE ELSE!!! CHRYSLER NEEDS TO FIX THE ISSUE, THERE IS A DEFECT. I EVEN CALLED HEADQUARTERS AND THEY'RE SAYING THEY CAN'T HELP BECAUSE THE TRUCK IS SO MANY YEARS OLD, AND BECAUSE OF THE MILEAGE. THING IS THEY KNEW WHAT WAS WRONG WITH THESE TRUCKS. CHRYSLER NEEDS TO FIX THIS ISSUE! !!!!! *TR

ON MARCH 29, 2014, MY 2004 CHRYSLER PACIFICA, PURCHASED IN AUGUST 2003, WAS INSPECTED AND DIAGNOSED, BY THE DEALERSHIP WHERE IT WAS PURCHASED, TO HAVE A SUBFRAME/ENGINE CRADLE THAT IS "ROTTING" OR IN OTHER WORDS, SEVERELY CRACKED AND CORRODED. I WAS NOT INFORMED OF THIS SERIOUS SAFETY ISSUE WITH MY VEHICLE BY CHRYSLER. I WAS INFORMED BY A RECENT INVESTIGATIVE STORY ON THE LOCAL CHICAGO NBC STATION, FOLLOWED BY INTERNET RESEARCH OF THE ISSUE. I CALLED THE CUSTOMER SERVICE NUMBER GIVEN TO ME FOR CHRYSLER AND WAS TOLD THAT THERE IS NOTHING THEY CAN DO TO ASSIST WITH THE $2600 COST OF REPLACEMENT, BECAUSE THE VEHICLE WAS NOT MADE IN THE NARROW WINDOW OF PRODUCTION THAT THEY CLAIM WAS AFFECTED AND SUBJECT TO RECALL. CHRYSLER TOLD ME THE WARRANTY THEY OFFERED, RELATED TO THE RECALL, WAS EXPIRED FOR MY VEHICLE ANYWAY. I NEVER RECEIVED ANY NOTIFICATION OF THE PROBLEM OR THAT WARRANTY, BECAUSE THEY WERE KEEPING THIS PROBLEM A SECRET TO MOST OF THEIR AFFECTED CUSTOMERS. I HAVE READ THAT CHRYSLER ALSO APPARENTLY SELECTIVELY DECIDES WHO TO HELP WITH THE COST OF REPAIRS, REGARDLESS OF THEIR RECALL WINDOW AND WARRANTY, AFTER THE CUSTOMER MAKES ENOUGH NOISE. IF IT IS NOT THEIR FAULT, WHY ARE THEY DOING THAT? ISN'T THIS THE SAME TYPE OF BEHAVIOR THAT TOYOTA AND CHEVROLET HAVE EXHIBITED? THE NBC REPORT ALSO INDICATES THAT NHTSA SEES NO PATTERN WITH THE NUMEROUS CLAIMS YOU HAVE RECEIVED OUTSIDE OF THE SUPPOSED RECALL WINDOW, LIKE THIS ONE, HOW MANY PEOPLE HAVE TO BE PUT AT GRAVE RISK BEFORE YOU SEE A PATTERN? YOU MIGHT SEE A PATTERN IF MORE PEOPLE KNEW THEY ARE DRIVING UNSAFE PACIFICAS, SO THAT THEY COULD REPORT IT. SORRY IF I AM BEING A BIT POINTED HERE, BUT THE I DON'T UNDERSTAND HOW CHRYSLER AND NHTSA CAN IGNORE THIS ISSUE. PLEASE RECONSIDER YOUR RECALL DECISION, AS CHRYSLER'S LIABILITY IS CERTAINLY MORE THAN A COUPLE MONTHS OF PRODUCTION. *TR

I SLOWED THE VEHICLE DOWN TO UNDER 40 IT WAS STILL TRYING SWERVE AND PULL. SCARED ME AND MY NIECE. HAS BEEN CLUNKING SINCE ABOUT SIX MONTHS AFTER I BOUGHT THE VEHICLE IN 2008.. SPENT OVER A GRAND ON NEW TIE RODS, SUSPENSIONS, WHEN I TOOK IT TO DIFFERENT DEALER FOR CHRYSLER VEHICLES WHERE A TECHNICIAN TOLD ME TO STOP WASTING MY MONEY, THEY KNOW THERE IS CLUNK AND DONT KNOW HOW TO FIX IT. I EMAILED AND LEFT MESSAGE FOR CHRYSLER WITH NO RESPINSE. LOOKS LIKE THEY KNOW HOW TO FIX IT BUT CHRYSLER WONT STAND BEHIND THEIR PRODUCT AND FIX THE PROBLEM TILL SOMEONE DIES AND THE FAMILIES OF THE DECEASED HAVE TO SUE THE COMPANY, SERIOUSLY! STAND BEHIND YOUR PRODUCT, I DONT THINK I WILL EVER PURCHASE A CHRYSLER VEHICLE AGAIN AND WILL INFORM ALL FRIENDS AND FAMILY TODO THE SAME. *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.
