THE FRONT BRAKE LINES FAILED UPON FRONTAL IMPACT. I AM A POLICE OFFICER/ACCIDENT INVESTIGATOR AND I INVESTIGATED AN ACCIDENT INVOLVING A 2002 MITSUBISHI MONTERO SPORT. THE DRIVER OF THE MONTERO IMPACTED THE REAR OF A VEHICLE AHEAD OF HER. THE IMPACT DAMAGED THE LEFT FRONT OF THE MONTERO ENOUGH TO DEPLOY THE AIR BAGS, BUT NOT ENOUGH TO PREVENT THE WHEEL FROM ROLLING. THE IMPACT ALSO CAUSED THE LEFT FRONT BRAKE LINE TO BREAK. THE LINE BROKE AT THE POINT WHERE THE FLEXIBLE RUBBER PART OF THE LINE CONNECTS TO THE METAL FITTING THAT IS ATTACHED TO THE INNER FENDER WELL. AFTER THE IMPACT, THE BRAKES WOULD NOT ALLOW THE DRIVER TO BRING THE VEHICLE TO A STOP AND THE VEHICLE THEN WENT OUT OF CONTROL AND IMPACTED A UTILITY POLE. THE SECOND IMPACT WAS ON THE RIGHT FRONT OF THE MONTERO AND IN A SIMILAR MANNER THE RIGHT FRONT BRAKE LINE BROKE. I AM STILL INVESTIGATING, BUT IT APPEARS THE BRAKE LINES WOULD NOT HAVE BEEN DAMAGED IF THE ATTACHMENT POINT OF THE BRAKE LINE WAS ON THE VEHICLE FRAME AND NOT ON THE INNER FENDER WELL. IT SEEMS WHEN THE FENDER WELL WAS BENT IN THE COLLISION THAT IS WHAT PUT STRESS ON THE RUBBER LINE AND CAUSED IT TO TEAR AWAY LEAVING THE VEHICLE WITHOUT BRAKING AND PREVENTING THE DRIVER FROM BRINGING IT SAFELY TO REST.*JB
I OWN A 2002 MITSUBISHI MONTERO, IT HAS BEEN IN 2 SEVERE HEAD ON IMPACTS, ONE AT OVER 35MPH.....NEITHER TIME HAS THE AIRBAGS DEPLOYED ON THIS VEHICLE. I HAVE CONTACTED MITSUBISHI, THEY MAINTAIN THE AIRBAGS HAVE WORKED PROPERLY, HOW THEY DETERMINE THIS, I DO NOT KNOW. THIS IS A MANUFACTURER DEFECT.
A MONTH AFTER MY VEHICLE WAS PURCHASED WE HAD A NUMBER OF PROBLEMS, THE REAR DIFFERENTIAL WAS CRACKED, LEAKING WINDSHIELD WASHER FLUID AND NOW THE STEERING ISN'T WORKING IN THE MANNER IT SHOULD. THE CAR IS ALL OVER THE ROAD AND WHILE STOPPING YESTERDAY THE STEERING WHEEL COMPLETELY ROLLED TO THE LEFT. THEN WHILE ON A GRAVEL ROAD…

A MONTH AFTER MY VEHICLE WAS PURCHASED WE HAD A NUMBER OF PROBLEMS, THE REAR DIFFERENTIAL WAS CRACKED, LEAKING WINDSHIELD WASHER FLUID AND NOW THE STEERING ISN'T WORKING IN THE MANNER IT SHOULD. THE CAR IS ALL OVER THE ROAD AND WHILE STOPPING YESTERDAY THE STEERING WHEEL COMPLETELY ROLLED TO THE LEFT. THEN WHILE ON A GRAVEL ROAD THE WHEEL COMPLETELY SPUN AROUND. I CALLED ANOTHER DEALERSHIP TODAY AND THEY SAID THERE WAS A RECALL ON THE STEERING, BUT THE MITSUBISHI HEADQUARTERS SAID THERE AREN'T ANY RECALLS.
AT 25 MPH SOMETHING BROKE AND THE VEHICLE MADE A SUDDEN LEFT TURN. *JB ***DIMSII IVOQ ENTRY POSTED AFTER 12/12/02 CUT-OVER TO ARTEMIS****770767

ON MAY 21, 2002 MY TWO RIGHT TIRES BLEW OUT WHILE I WAS GOING APPROXIMATELY 30 MPH. AS A RESULT OF THE BLOW OUT MY CAR COLLIDED WITH THE GROUND AND WENT OUT OF CONTROL. LUCKILY THERE WERE NO FATALITIES. ALSO IT WAS DETERMINED THAT A BRAND NEW FRAME WAS NEEDED BECAUSE THE COLLISION WAS SO BAD. POLICE DID REPORT TO THE SCENE AND COULD FIND NO DEBRIS IN THE ROAD TO CAUSE THE BLOW OUT. MY CAR IS STILL IN THE SHOP. IT HAS BEEN THERE SINCE MAY 21, 2002. THANK YOU DT

IN OCTOBER 2001, MITSUBISHI NOTIFIED THE AGENCY THAT IT WOULD CONDUCT A SAFETY RECALL (NHTSA RECALL NO. 01V-254) TO REMEDY A DEFECT CONDITION THAT COULD RESULT IN A LEAK OF PRESSURIZED NITROGEN GAS FROM THE HYDRAULIC BRAKE BOOSTER ACCUMULATOR IN APPROXIMATELY 39,000 MODEL YEARS (MY) 2001-2002 MITSUBISHI MONTERO VEHICLES PRODUCED FROM DECEMBER 12, 1999 THROUGH JUNE 20, 2001. ACCORDING TO MITSUBISHI, THE ACCUMULATOR THAT IS INSTALLED ON THE HYDRAULIC BRAKE BOOSTER MAY HAVE BEEN MANUFACTURED IMPROPERLY, WHICH OVER A PERIOD OF TIME MAY RESULT IN LEAKAGE OF THE PRESSURIZED NITROGEN GAS FROM INSIDE THE ACCUMULATOR. THE LOSS OF THIS GAS PRESSURE MAY RESULT IN AN ABNORMAL NOISE FROM THE LEFT SIDE OF THE DASH PANEL WHEN THE BRAKES ARE APPLIED, AND POSSIBLY A DELAYED FIRST TIME BRAKE BOOST ASSIST AFTER THE VEHICLE HAS BEEN PARKED FOR A PERIOD OF TIME.DURING RQ06-007, MITSUBISHI INDICATED THAT THE DECISION TO CONDUCT RECALL 01V-254 WAS BASED ON PROJECTED FAILURE RATES OF 36.5% WITHIN 2-YEARS OF SERVICE AND 100% IN THE FIRST 4-YEARS OF SERVICE. THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED RQ06-007 BASED ON SIX COMPLAINTS OF HYDRAULIC BRAKE BOOSTER ACCUMULATOR FAILURE IN THE APPROXIMATELY 23,335 MY 2002 MONTERO VEHICLES THAT WERE BUILT AFTER THE VEHICLES RECALLED IN 01V-254.ONE OF THE COMPLAINTS ALLEGED THAT THE FAILURE RESULTED IN A CRASH.DURING THE INVESTIGATION, ODI IDENTIFIED 20 CONSUMER COMPLAINTS AND 58 WARRANTY CLAIMS RELATED TO BRAKE BOOSTER ACCUMULATOR FAILURE IN THE SUBJECT VEHICLES, RESULTING IN A COMPLAINT RATE OF APPROXIMATELY 85 PER 100,000 VEHICLES AND A WARRANTY CLAIM RATE OF 0.25%.MITSUBISHI?S PROJECTED ACCUMULATOR FAILURE RATES AT 2- AND 4-YEARS IN SERVICE FOR THE SUBJECT VEHICLES WERE 0.5% AND 1.3% RESPECTIVELY AND ODI?S ANALYSES PRODUCED SIMILAR RESULTS.ODI?S INVESTIGATION FOUND THAT THE INCIDENTS OF INCREASED BRAKE PEDAL EFFORT TYPICALLY OCCURRED WITHIN THE FIRST FEW SECONDS AFTER THE ENGINE WAS STARTED AND WERE ACCOMPANIED BY NOISE ASSOCIATED WITH THE ACCUMULATOR CHARGING.ODI?S INVESTIGATION OF THE CRASH INCIDENT CONCLUDED THAT IT COULD NOT BE ATTRIBUTED TO THE ALLEGED DEFECT CONDITION.ODI ALSO COLLECTED AND ANALYZED DATA FOR POST-REMEDY ACCUMULATOR FAILURES IN VEHICLES THAT HAD THE 01V-254 REPAIRS COMPLETED.MITSUBISHI PROVIDED DATA DURING THE INVESTIGATION THAT INDICATED 95% OF THE RECALLED VEHICLES HAD RECEIVED THE RECALL REMEDY.FOR THESE VEHICLES, THERE WERE 14 COMPLAINTS AND 249 WARRANTY CLAIMS IDENTIFIED, RESULTING IN A COMPLAINT RATE OF 28 PER 100,000 VEHICLES AND A WARRANTY CLAIM RATE OF 0.64%.ANALYSIS OF THESE FAILURES SHOWED A DECLINING TREND WITH INCREASING VEHICLE AGE, WITH ALMOST HALF OF THE WARRANTY CLAIMS OCCURRING WITHIN THE FIRST 12-MONTHS AFTER RECEIVING THE RECALL REMEDY.

ACCORDING TO MITSUBISHI, THE ACCUMULATOR THAT IS INSTALLED ON THE HYDRAULIC BRAKE BOOSTER MAY HAVE BEEN MANUFACTURED IMPROPERLY, WHICH OVER A PERIOD OF TIME MAY RESULT IN LEAKAGE OF THE PRESSURIZED NITROGEN GAS FROM INSIDE THE ACCUMULATOR. THE LOSS OF THIS GAS PRESSURE MAY RESULT IN AN ABNORMAL NOISE FROM THE LEFT SIDE OF THE DASH PANEL WHEN THE BRAKES ARE APPLIED, AND POSSIBLY A DELAYED FIRST TIME BRAKE BOOST ASSIST AFTER THE VEHICLE HAS BEEN PARKED FOR A PERIOD OF TIME.DURING RQ06-007, MITSUBISHI INDICATED THAT THE DECISION TO CONDUCT RECALL 01V-254 WAS BASED ON PROJECTED FAILURE RATES OF 36.5% WITHIN 2-YEARS OF SERVICE AND 100% IN THE FIRST 4-YEARS OF SERVICE. THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED RQ06-007 BASED ON SIX COMPLAINTS OF HYDRAULIC BRAKE BOOSTER ACCUMULATOR FAILURE IN THE APPROXIMATELY 23,335 MY 2002 MONTERO VEHICLES THAT WERE BUILT AFTER THE VEHICLES RECALLED IN 01V-254.ONE OF THE COMPLAINTS ALLEGED THAT THE FAILURE RESULTED IN A CRASH.DURING THE INVESTIGATION, ODI IDENTIFIED 20 CONSUMER COMPLAINTS AND 58 WARRANTY CLAIMS RELATED TO BRAKE BOOSTER ACCUMULATOR FAILURE IN THE SUBJECT VEHICLES, RESULTING IN A COMPLAINT RATE OF APPROXIMATELY 85 PER 100,000 VEHICLES AND A WARRANTY CLAIM RATE OF 0.25%.MITSUBISHI?S PROJECTED ACCUMULATOR FAILURE RATES AT 2- AND 4-YEARS IN SERVICE FOR THE SUBJECT VEHICLES WERE 0.5% AND 1.3% RESPECTIVELY AND ODI?S ANALYSES PRODUCED SIMILAR RESULTS.ODI?S INVESTIGATION FOUND THAT THE INCIDENTS OF INCREASED BRAKE PEDAL EFFORT TYPICALLY OCCURRED WITHIN THE FIRST FEW SECONDS AFTER THE ENGINE WAS STARTED AND WERE ACCOMPANIED BY NOISE ASSOCIATED WITH THE ACCUMULATOR CHARGING.ODI?S INVESTIGATION OF THE CRASH INCIDENT CONCLUDED THAT IT COULD NOT BE ATTRIBUTED TO THE ALLEGED DEFECT CONDITION.ODI ALSO COLLECTED AND ANALYZED DATA FOR POST-REMEDY ACCUMULATOR FAILURES IN VEHICLES THAT HAD THE 01V-254 REPAIRS COMPLETED.MITSUBISHI PROVIDED DATA DURING THE INVESTIGATION THAT INDICATED 95% OF THE RECALLED VEHICLES HAD RECEIVED THE RECALL REMEDY.FOR THESE VEHICLES, THERE WERE 14 COMPLAINTS AND 249 WARRANTY CLAIMS IDENTIFIED, RESULTING IN A COMPLAINT RATE OF 28 PER 100,000 VEHICLES AND A WARRANTY CLAIM RATE OF 0.64%.ANALYSIS OF THESE FAILURES SHOWED A DECLINING TREND WITH INCREASING VEHICLE AGE, WITH ALMOST HALF OF THE WARRANTY CLAIMS OCCURRING WITHIN THE FIRST 12-MONTHS AFTER RECEIVING THE RECALL REMEDY. DUE TO THE LOW FAILURE RATES, ABSENCE OF RELATED CRASHES, AND NO INDICATION OF INCREASING FAILURE TRENDS IN EITHER THE SUBJECT VEHICLES OR POST-REPAIR RECALL POPULATION THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.
