THE POWER BRAKE MASTER CYLINDER POWER BOOSTER ACCUMULATOR IS DEFECTIVE AS OUTLINED ION YOUR RECALL 01-V254-001. I MADE AN APPOINTMENT AT BERGSTROM AUTOMOTIVE APPLETON WI TO REPAIR THE PROBLEM.

PLEASE BE KNOWN THAT MY VEHICLE HAS THE RECALL PROBLEM AS STATED IN THE NHTSA NOTIFICATION. THEY CLAIMED MY VEHICLE DOES NOT QUALIFY FOR THE RECALL DUE TO THE PRODUCTION DATE OF MY VEHICLE BUT I DID NOT CARE WE JUST NEEDED TO GET THE CAR FIXED. AN APPOINTMENT WAS MADE ON 7/20/15 TO HAVE THE REPAIR MADE. BERGSTROM CONFIRMED ON 7/14/15 THAT THE PARTS ARRIVED. AN APPOINTMENT WAS MADE FOR 7/24/15 TO FIX THE ACCUMULATOR. WE DROVE 2 HOURS TO THE BERGSTROM'S FOR THIS APPOINTMENT, WAITED 2 1/2 HOURS IN THEIR SHOW ROOM FOR THEM TO MAKE THE REPAIR, AND DROVE 2 HOURS HOME. WHEN STACY THE SERVICE CONSULTANT SPOKE WITH US SHE PROCEEDED TO GLAZE OVER THE ACCUMULATOR AND PROCEEDED TO DISCUS THE HEADLIGHT REPAIR WHICH I NEVER REQUESTED.

TO SUM IT UP: REPAIR NOT MADE, SAID IT WAS COVERED THEN NOT COVERED UNDER THE RECALL. WAS TOLD THAT IT WAS. 6 1/2 HOURS WASTED.

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.
