TL* THE CONTACT OWNS A 2002 MITSUBISHI MONTERO SPORT. WHEN THE STEERING WHEEL WAS TURNED LEFT OR RIGHT AT A CERTAIN ANGLE, THE HORN OF THE VEHICLE ACTIVATED INDEPENDENTLY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT AN UNKNOWN MODULE RELATED TO THE AIR BAG AND A RELAY SWITCH NEEDED TO BE REPLACED. THE RELAY SWITCH WAS REPLACED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 155,000.

2002 MITSUBISHI MONTERO SPORT; THE CAR HORN/ALARM GOES OFF USUALLY WHEN A DROP OF TEMPERATURE OCCURS IN THE MIDDLE OF THE NIGHT. TO FIX ... HAS SOMETHING TO DO WITH A SHORT IN THE ELECTRICAL OF THE AIR BAG AND THE STEERING WHEEL COLUMN. VERY EXPENSIVE FOR A MECHANIC, OVER $1200. I HAVE TO UNHOOK MY BATTERY EVERY NIGHT AND ON COLDER DAYS. RESEARCHING ONLINE.....A LOT OF PEOPLE ARE DISABLING THE HORN/ALARM SYSTEM AND DRIVING WITHOUT HORNS. OR THEY ARE TAMPERING WITH THE AIR BAG TO TRY AND FIX. IT IS A VERY COMMON PROBLEM....... TODAY I COULD NOT DRIVE THE CAR BECAUSE EVERY TIME I HOOKED THE BATTERY CABLE BACK UP THE HORN STAYED ON. I AM CONSIDERING DISABLING THE HORN ALTOGETHER. *TR

2002 MITSUBISHI MONTERO SPORT. THE HORN SOUNDS FOR NO REASON, WHEN THE TEMPERATURE DROPS BELOW 55DEGREES. I MUST REMOVE THE FUSE TO SILENCE IT. IT IS STATE REQUIRED SAFETY EQUIPMENT.

HORN BUTTON WHEN THE ACCESSORY SOCKET IS IN USE OR NOT IN USE,THE HORN CONTINUES TO BLOW WHEN THE BUTTON IS RELEASED. THEREFORE THE FUSE TO THE HORN MUST BE DISCONNECTED AT ALL TIMES. I HAD IT PUT ON A DIAGNOSTIC MACHINE AND IN ORDER TO HAVE THIS FIXED IT WILL COST $1300 BECAUSE THE PROBLEM HAS TO DO WITH THE AIR BAG. IF IT WERE THE RELAY SWITCH IT WOULD HAVE BEEN $24. THIS IS NOT FROM WHAT I THINK IS SOMETHING THAT CONSUMERS MUST PAY FOR. I LIVE IN THE STATE OF VIRGINIA WHERE IT IS REQUIRED TO HAVE VEHICLE SAFETY INSPECTION DONE EVERY YEAR AND THE FIRST THING THAT'S CHECKED IS THE HORN. HOW CAN SOMETHING THAT NEEDS TO BE OPERABLE THAT'S OUT OF THE NORMAL WEAR AND TEAR NOT BE A RECALL? THIS HAS BEEN GOING ON SINCE 2007 AND I STILL HAVE NOT GOTTEN A RESPONSE FROM ANYONE ON THIS MATTER. EVERY YEAR I'VE BEEN SKATING BY CROSSING MY FINGERS AND HOPE THAT THE HORN WILL NOT SOUND OFF. HERE RECENTLY I CAN'T PUT THE FUSE IN AT ALL WITHOUT THE HORN CONTINUALLY SOUNDING OFF. IT SOUND LIKE SOMEONE IS JUST SITTING IN MY CAR HOLDING THEIR HAND DOWN ON THE HORN... THIS HAS BEEN GOING ON SINCE 2007 PRIMARILY WHEN IT'S COLD OUTSIDE TO NOW 2010. THERE HAS BEEN NUMEROUS TIMES IN THIS TIME FRAME WHERE I COULD HAVE USED THE HORN TO PREVENT SOMEONE FROM ALMOST HITTING ME. *TR
DURING COLD WEATHER (APPROXIMATELY 20 DEGREES C AND BELOW) THE HORN STARTS BLOWING AND WON'T TURN OFF UNLESS THE BATTERY IS DISCONNECTED OR THE CAR INTERIOR HAS WARMED UP. THE ONLY WAY I HAVE TO PREVENT THE HORN FROM COMING ON IS TO KEEP THE HORN/AIR/BAG ASSEMBLY WARM. I WRAP AN ELECTRIC BLANKET AROUND THE STEERING WHEEL. *JB

DEALERSHIP SAID THERE IS SLUDGE IN ENGINE DUE TO "LACK OF PROPER MAINTENANCE". WE'VE HAD THE OIL CHANGED ACCORDING TO THE MANUAL BUT BELIEVE THAT THE OIL PAN IS POSITIONED WRONG AS THE DEALERSHIPS TOLD US THAT ABOUT 1/4 INCH TO 1/2 INCH IS ALWAYS LEFT IN THE BOTTOM OF THE OIL PAN WHEN YOU CHANGE THE OIL, THEREFORE CREATING SLUDGE. THE OIL PUMP HAS ALSO GONE BAD ON THIS 2002 MITSUBISHI MONTERO SPORT, WITH 62,000 MILES. NO ONE WILL PICK UP THE BILL, EVEN THOUGH WE PAID FOR AN EXTENDED WARRANTY. WE'VE ALSO PUT THREE ALTERNATORS ON IT IN ONE MONTH AND HAD THE CAM SEALS REPLACED. CAM SEALS ALSO SEEM TO BE A COMMON PROBLEM WITH THOSE CARS, ACCORDING TO ONE TECHNICIAN. THESE PROBLEMS HAVE BEEN GOING ON SINCE NOVEMBER 2003. CB

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.

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.
