2008 Mitsubishi Lancer Evolution

ACD (ACTIVE CENTER DIFFERENTIAL) PUMP HAS FAILED AND WITHOUT THIS PUMP PROVIDING PRESSURE TO THE ALL WHEEL DRIVE SYSTEM, THE VEHICLE GETS STUCK ON DRIVEWAYS AT A STOP WHERE THE TIRE AND WHEEL PACKAGES ARE ON DIFFERENT ELEVATED SURFACES. THE REASON THE PUMP HAS FAILED IS DUE TO PLACEMENT OF THE PUMP ON THE VEHICLE. MITSUBISHI HAS DESIGNED THE VEHICLE TO HAVE THE PUMP TO BE LOCATED DIRECTLY BEHIND THE REAR PASSENGER WHEEL. DUE TO THIS, WHILE DRIVING ON SEVERE WEATHER ROADS (PARTICULARLY SNOW SALTED ROADS), THE DIRT, WATER AND SALT GETS KICKED UP TO THE POSITION OF THE PUMP WHICH CORRODES THE FITTINGS AND THE PUMP ITSELF. THIS THEN CAUSES THE PUMP TO FAIL OVER TIME. IT COULD HAVE BEEN EASILY REMEDIED BY RELOCATING THE PUMP OR ANTI-CORROSION PROTECTION AND BETTER SEALING. BEING LOCATED IN SOUTHERN CALIFORNIA, I WOULD HAVE THOUGHT THAT THIS WOULD HAVE NEVER HAPPENED TO ME, BUT EVEN DRIVING ONLY TWICE THROUGH SNOW ROADS IN THE PAST 3 YEARS HAS CORRODED THE PUMP TO FAILURE. MITSUBISHI HAS DENIED THAT THIS IS PART OF THE POWER TRAIN WARRANTY, WHICH MEANS IT WILL BE A $2000+ DOLLAR FIX. *TR

ACD (ACTIVE CENTER DIFFERENTIAL) PUMP FAILURE AT 43000 MILES. WAS REPAIRED UNDER WARRANTY BUT FAILED AGAIN 2 MONTHS AGO (LESS THAN 60000 MILES) JANUARY 2014. SO THE NEW PUMP INSTALLED DID NOT LAST FOR MORE THAN 15000 MILES. THIS IS A COMMON AND KNOWN ISSUE FOR ALL MITSUBISHI MODELS EQUIPPED WITH THAT ACD STABILITY CONTROL. *TR

AS MANY EVOLUTION OWNERS WHO LIVE IN THE MIDWEST CAN ALSO ATTEST, MY EXAMPLE NOW JOINS THE CLUB OF MODELS WITH DEFECTIVE ASC/AYC PUMP FAILURE. THE PUMP FAILS WHEN OUTSIDE TEMPERATURES RUN CLOSE TO FREEZING, ON TOP OF THE UNIT CORRODING, AND EVOLUTION OWNERS ARE BEING FORCED TO SHELL OUT $1800 MINIMUM TO MITSUBISHI FOR THE PUMP ALONE, NOT INCLUDING LABOR. I BELIEVE THIS HAS ONLY OCCURRED TO MY MITSUBISHI AFTER SIX YEARS BECAUSE I'VE BEEN VERY GOOD ABOUT KEEPING THE UNDERBODY CLEAN, AND IT'S NEARLY ALWAYS PARKED IN A HEATED GARAGE. WITHOUT THE PROPER FUNCTIONING OF THIS INTEGRAL DRIVETRAIN EQUIPMENT, WE AREN'T ABLE TO CONTROL POWER DELIVERY FRONT TO BACK AND THE VEHICLE COMPUTER GOES INTO A TYPE OF LIMP MODE WHERE NO CONTROL OF THE DELIVERY OF POWER TO THE WHEELS IS POSSIBLE. OF COURSE THE BRAKES WORK AND THE THROTTLE WORKS, BUT WHEREAS THE VEHICLE USED TO BE SELECTABLE FOR SNOW OR GRAVEL MODES, GREATLY IMPROVING TRACTION AND THE ABILITY TO LIMIT SLIPPAGE OF THE REAR WHEELS, WE INSTEAD STARE AT A DIGITAL READOUT INSTRUCTING US TO SERVICE THE UNIT THAT'S CORRODED AND THE PUMP HAS OVERHEATED AND ALSO FAILED AS A RESULT. WWW.EVOXFORUMS.COM AND WWW.EVOLUTIONM.NET HAS PLENTY OF OTHER CUSTOMERS WHO ARE BELONG FRUSTRATED WITH THIS ISSUE THAT MITSUBISHI DOESN'T WANT TO ADDRESS. NEARLY ALL OF US HAVE SPENT GOOD MONEY ON A VEHICLE WE THOUGHT WOULD BE A SOLID PERFORMER IN BOTH THE DRY, WET, AND SNOW AND INSTEAD, SOME OWNERS HAVE TO PAY NOT ONCE TO REMEDY THIS UNIT THAT'S FAILING ON ALL OUR CARS, BUT I'VE HEARD OF OWNERS HAVING TO DO IT TWO AND EVEN THREE TIMES. OWNERS ARE TRYING TO SAVE MONEY BY BREAKING DOWN THE UNIT AND REPAIRING THE INTERNAL MOTOR. PEOPLE ARE EXPERIMENTING WITH WAYS TO PREVENT THE UNITS THEY PURCHASE TO PREVENT THEM FROM RUSTING AND CORRODING. PLEASE PLEASE PLEASE CONTACT MITSUBISHI AND HELP US?? *TR

VERY COLD DAY OUT, ABOUT -15 F, WARMED UP MY VEHICLE FOR ABOUT 5 MINUTES PLUS. ONCE I BEGAN DRIVING, ABOUT 10 MPH MY SERVICE REQUIRED LIGHT CAME ON FOR MY AYC PUMP. DEALER SAID THAT IS WAS NOT COVERED UNDER WARRANTY OF ANY KIND. MITSUBISHI HAS KNOWN THAT IS A COMMON ISSUE IN COLD CLIMATES THAT USE SALT ON THE ROADS. THE SALT CORRODES THE PUMP AND MAKES IT FAULTY/MALFUNCTION. THIS IS A SAFETY ITEM THAT NEEDS TO BE RECALLED DUE TO THE KNOWLEDGE THAT AN EVO DRIVER HANDLES THEIR CAR [THAT THEY PURCHASED AS SUCH] AND LOOSES THAT RIGHT WITH A FAULTY AYC PUMP. *TR

I STARTED MY CAR AND THE AWC SERVICE LIGHT CAME ON. IT WAS ABOUT 0 DEGREES OUT THAT DAY, WHICH IS A VERY UNUSUAL TEMPERATURE FOR S. INDIANA. WHEN I STARTED THE CAR IT SCREECHED FOR JUST A SECOND AND THEN POPPED UP THE CODE. I RESTARTED THE CAR, JUST AS THE MANUAL HAD SAID AND WHEN I RESTARTED IT THE LIGHT WAS STILL ON. I WAS ABLE TO GET THE CODE READ IT THREW A C161E CODE WHICH IS AN ACD/AYC PROBLEM. AFTER DOING A LOT OF RESEARCH I FOUND OUT ITS A COMMON PROBLEM AND ITS AN EXPENSIVE PROBLEM, ABOUT $2,000+. I CALLED THE DEALER AND WAS TOLD MY WARRANTY DOES NOT COVER THIS, IT IS NOT PART OF THE POWER TRAIN. *TR

I STARTED MY CAR AND THE AWC SERVICE LIGHT CAME ON. I CAME TO A CONTROLLED STOP, AND RESTARTED THE CAR PER THE INSTRUCTIONS IN THE VEHICLE MANUAL. UPON RESTART, THE SAME SERVICE LIGHT CAME ON. AFTER THE DEALER RAN A DIAGNOSTIC, IT WAS FOUND THAT THE HIGH PRESSURE PUMP FOR THE ACTIVE STABILITY CONTROL SYSTEM HAD FAILED. I WAS TOLD THAT THIS PART WAS NOT PART OF THE DRIVE TRAIN AND WOULD NOT BE COVERED UNDER WARRANTY. THE DAY THE PUMP FAILED IT WAS VERY COLD AND THERE WAS PACKED SNOW ON THE ROADWAYS. IF I WAS DRIVING AT HIGHER SPEEDS AND THIS PUMP HAD FAILED, I BELIEVE THE AUTOMOBILE WOULD NOT HAVE BEHAVED AS EXPECTED WITH THE AWC STABILITY ACTIVE. *TR

THIS IS REPORT OF A KNOWN FAILURE BY MITSUBISHI MOTOR CORP. AT 50,800 MILES ON 12/17/2013 MY CARS SUPER-ACTIVE CENTER DIFFERENTIAL (S-ACD) STARTED BLINKING AT ME. IT WOULD NOT ALLOW CHANGING OF THE SETTINGS ANYMORE FOR TARMAC/GRAVEL/SNOW. IMMEDIATELY THERE AFTER, THE DRIVER INFORMATION PANEL POPPED UP WITH A YELLOW "AWD SERVICE REQUIRED" INDICATOR. I BROUGHT MY CAR TO NASHUA, NH MITSUBISHI/HYUNDAI FOR DIAGNOSIS ON 12/19/2013. THERE THEY APPLIED TSB-SC11-002. THIS UNFORTUNATELY DID NOT RESOLVE THE ISSUE. I WAS THEN INFORMED THAT THE CAR REQUIRED A REPLACEMENT ACD PUMP AND WAS QUOTED $1,995 FOR THE REPAIR, WHICH CONFUSED ME DUE TO THE FACT THAT MY CAR WAS STILL UNDER MANUFACTURERS POWER TRAIN WARRANTY, AND A PUMP, THAT CONTROLS THE AWD SYSTEM OF A CAR, SEEMS TO BE POWER TRAIN RELATED, AT LEAST IN MY EYES. THE NORTH EAST REGIONAL REPRESENTATIVE WAS CONTACTED ON MY BEHALF BY THE DEALERSHIP TO REQUEST COVERAGE OF THIS ITEM, WHICH WAS ULTIMATELY DENIED. THIS IS A SEVERE SAFETY ISSUE, AS THE CAR NO LONG HANDLES PROPERLY IN CONDITIONS IT WAS DESIGNED FOR. I AM NO LONGER ABLE TO SELECT THE CAR FOR SNOW, LIVING IN THE NORTH EAST, DRIVING A CAR MARKETED IN THE NORTH EAST, THIS IS A HUGE PROBLEM. TO FURTHER THE ISSUE, THIS PROBLEM IS WELL KNOWN BY MITSUBISHI, IT HAS BEEN DOCUMENTED WELL, TRACING ALL THE WAY BACK TO CARS MANUFACTURED IN 2006. 90% OF ALL PUMP FAILURES COULD BE COMPLETELY ELIMINATED BY ADDING A SEAL TO STOP CORROSION INSIDE THE PUMP WHICH LEADS TO THE UNTIMELY FAILURES. IF NO RECALL IS ISSUED FOR THIS FAILURE, AT THE VERY LEAST, MITSUBISHI MOTORS SHOULD BE FORCED TO COVER THIS UNDER POWER TRAIN WARRANTY FOR 5YRS/60K MILES. INSTEAD OF LIMITING IT TO 3YRS/36K BUMPER TO BUMPER. LINK TO DOCUMENTED CASES - HTTP://FORUMS.EVOLUTIONM.NET/EVO-X-GENERAL/655162-THOSE-YOU-ACD-PUMP-FAILURES-MERGED.HTML. *TR

(COMPLAINT IS APPLICABLE ONLY TO GSR TRIM EQUIPPED WITH A 5MT TRANSMISSION) - DIFFICULTY SHIFTING FIRST TO SECOND GEAR, AND SECOND TO THIRD. GEARSHIFT IS NOTCHY AND HARD TO ENGAGE. CAUSES LONGER THAN DESIRABLE TIME-GAP IN POWER TO THE WHEELS, RESULTING IN LOSS OF SPEED DURING ACCELERATION PHASE FROM A STOP. - GEARSHIFT IS NOT SMOOTH IN GENERAL. KEYWORDS : NOTCHY, GRINDING. - IT IS A WIDELY REPORTED PROBLEM IN THIS PARTICULAR MODEL AS EVIDENT FROM OWNER SURVEYS ON A PROMINENT INTERNET FORUM (SEE HTTP://FORUMS.EVOLUTIONM.NET/EVO-X-ENGINE-TURBO-DRIVETRAIN/333385-OFFICIAL-EVO-X-NOTCHY-GRINDING-TRANSMISSION-THREAD.HTML). *TR

THIS VEHICLE IS EQUIPPED WITH AN ACTIVE CONTROL DIFFERENTIAL (ACD) WHICH IS ACTUATED BY THE ACD HYDRAULIC PUMP. THE ACD IS A PART OF THE VEHICLE'S ALL WHEEL DRIVE SYSTEM. AFTER GIVING THE ENGINE AN 8 MINUTE WARM UP ON IDLE, THE VEHICLE WAS BEING DRIVEN ON A 20F OF AMBIENT TEMPERATURE. THE VEHICLE WAS ON A STOP LIGHT, AND UPON GENTLY ACCELERATING THE CAR ON GREEN LIGHT A WARNING LIGHT CAME UP ON THE VEHICLE'S DASH BOARD. THE VEHICLE WAS BROUGHT TO THE NEAREST MITSUBISHI SERVICE SHOP 4 DAYS AFTER THE INCIDENT WITH THE WARNING LIGHT STILL ON THE VEHICLE'S DASH BOARD. AFTER SERVICE TECHNICIAN WORKED ON THE VEHICLE, THE SERVICE MANAGER SAID THAT THE ACD PUMP IS THE PROBLEM WHICH NEEDS TO BE REPLACED AND WILL COST $2100 OF PARTS AND LABOR. 8 MONTHS PRIOR TO THE INCIDENT, THE MITSUBISHI SERVICE SHOP RE-FLASHED MY VEHICLE'S ALL WHEEL DRIVE ECU TO SPECIFICALLY PREVENT THE FAILURE OF THE PUMP ESPECIALLY IN COLD ENVIRONMENTS. MITSUBISHI REPLACED THE ACD PUMP AT MY EXPENSE, AND IT'S BEEN APPROXIMATELY 2 YEARS THAT MY VEHICLE IS ON THE REPLACEMENT PUMP. THE SERVICE MANAGER TOLD ME THAT THE COMBINATION OF THE HYDRAULIC FLUID BECOMING THICK ON COLD WEATHER AND THE CORROSION ON THE HYDRAULIC PUMP THAT THE SALTED WINTER ROADS BRING IS WHAT MAKES THE ACD PUMP FAIL. AFTER RESEARCHING ON THE INTERNET CAR FORUMS, THIS OCCURRENCE WHERE THE ACD PUMP FAILS ON COLDER REGIONS IS NOT UNCOMMON EVEN WITH THE PREVIOUS GENERATIONS OF THIS VEHICLE THAT ARE EQUIPPED WITH THIS ACD SYSTEM. *TR
