The battery has been drained on three separate occasions this year (2021). I replaced the battery after the first occurrence. Each time I have had to use a battery jump to restart the vehicle which sufficed to get it operating and return home. On the last occasion, the car started to display dash board warning messages before arriving at home after driving only 15 miles. This came with a fully charged battery installed to get the car restarted. Previously I could see no error codes, but following this latest incident the AWD error code 77-01 is displayed by an OBD reader. The vehicle began to run roughly and flashed many dashboard warnings as the battery began to draw down to zero power. Latest incident required a battery replacement instead of just a jump to restart.

HFL MODULE # 39770-STX-A011-M1 STOPPED WORKING PREVENTING CONNECTION TO MY CELL PHONE. 2009 MDX WITH 92,004 MILES. CALLED ALL THE DEALERSHIPS IN MY AREA AND OTHERS ON THE INTERNET AND NO ONE HAS THE MODULE. I WAS TOLD BY THEM IT'S ON NATIONAL BACK ORDER FOR SONE TIME NOW ( 2/5/2020 ) . DOING FURTHER RESEARCH BROUGHT TO LIGHT THERE IS A 2016 OR 2017 CLASS ACTION SUIT ON THIS HFL MODULE/SYSTEM FAILING AND DRAINING POWER FROM THE BATTERY, CAUSING PREMATURE FAILURE OF SAID BATTERY, WHICH ALSO HAPPENED TO ME AS WELL AS NO START CONDITIONS WHICH ALSO HAS HAPPENED TO ME. SO FAR NO STALL OUTS WITH THE VEHICLE MOVING. I CURRENTLY HAVE A HFL MODULE ON ORDER FROM ACURA AND WAS TOLD BECAUSE THEIR ON BACK ORDER IT COULD BE SEVERAL MONTHS BEFORE THEY GET THEIR ORDER. ALSO THEY WANT MY OLD MODULE WHICH THEY ADDED A $50.00 CORE CHARGE TO THE PRICE. THOUGH THERE MAYBE JUST A FEW OFFICIAL COMPLAINTS LISTED HERE JUST CHECK THE WEB. THERE IS OBVIOUSLY A FAULT IN THESE MODULES AND THE MANUFACTURE IS EITHER DOING REVERSE FAILURE ANALYSIS ON THE RETURNED MODULES OR WIRSE YET FIXING THE BROKEN ONES AND SENDING THEM OUT AS THE REPLACEMENTS. EITHER WAY THEY OBVIOUSLY KNOW IS WRONG WITH THESE MODULES. THIS MODULE IS NOT WHAT IS CONSIDERED A NORMAL ATTRITION PIECE LIKE TIRES, BRAKES, LIGHT BULBS , BELTS , HOSES. WHEN WAS THE LAST TIME YOU PLANNED ON REPLACING A BROKEN RADIO IN YOUR VEHICLE, YOU DON'T. I SHOULDN'T HAVE TO PLAN OR PAY TO REPLACE MY HFL MODULE, QUALITY CONTROL AND MANUFACTURE LOYALTY TO THEIR CUSTOMERS IS ABISMAL.

THE BLUETOOTH MODULE DRAINS THE BATTERY WHEN THE VEHICLE IS TURNED OFF AND I AM AFRAID THAT MY VEHICLE COULD BE TURNED OFF BY DRAINING THE BATTERY WHEN RUNNING CAUSING A SAFETY ISSUE. I HAVE REGISTERED THE CASE WITH ACURA CUSTOMER SERVER AND HAVE NOT HELPED ME WITH THE FREE REPLACEMENT. THE ACURA CASE NUMBER IS [XXX] 2009 ACURA MDX AWD VIN: 2HNYD28679H[XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TT

BLUETOOTH HANDFREE LINK (HFL) IN MY 2009 ACURA MDX WAS DRAINING MY BATTERY. I HAD TO CALL TOWING SERVICE A FEW TIMES TO START THE VEHICLE. WHEN I OPENED THE COMPARTMENT WHERE HANDS FREE LINK DEVICE IS LOCATED, I NOTICED THAT THE DEVICE WAS EXTREMELY HOT (FIRE HAZARD). FINALLY, IT GAVE UP AFTER A WHILE. THIS HAPPENED AFTER MY EXTENDED WARRANTY EXPIRED AT 100K MILES. MY STATE (STATE OF ILLINOIS) REQUIRES USING A HANDS FREE LINK WHILE DRIVING, SO, I FEEL ACURA SHOULD RECALL THE HFL UNIT AND REPLACE THIS FREE OF CHARGE TO COMPLY WITH THE STATE LAW. WILL APPRECIATE IF NHTSA LOOKS INTO THIS CASE AND REQUIRES ACURA/HONDA TO ISSUE AN IMMEDIATE RECALL. THIS IS A VERY COMMON ISSUE IN MANY ACURAS BASED ON MY GOOGLE SEARCH.

MY MDX HAS ONLY 62,400 MILES AND TODAY I GOT A MESSAGE "CHECK STARTER SYSTEM" DUE TO THE HFL MODULE IS DRAINING THE BATTERY. LUCKILY THE CAR WAS IN MY GARAGE AT THE TIME. I HAD TO CHARGE THE BATTERY SO I COULD START THE CAR. ALL THE INFO I HAVE READ ONLINE STATES THE THE HFL MODULE GETS REAL HOT AND CAN CAUSE FIRE. MY GARAGE IS UNDER MY BEDROOM. THIS IS A PART MADE BY JOHNSON CONTROLS, ACURA NEEDS TO RECALL THIS ITEM.

AIR BAGS

On Jan 21, 2025 the drivers side air bag deployed as I was driving. I did not hit or get hit by anyone or anything, I did not run over anything either the airbag deployed on drivers side from the front to the back of my Acura MDX it was sudden it was random Nd damn scary. I was injured from the impact of the air bag ... I have had my car approximately 6 months I am purchasing from Drive now in Wichita, KS and am still making payments on this vehicle..
Jan 30, 2025
Vehicle produced a dash warning light for airbag/supplemental restraint system on January 29th or 30th, 2022. Went away and back on again 3 times in the following week. No prior issues related to this. Vehicle has never been in an accident. Acura dealer scanned vehicle 2/5/2022 to find vehicle code 11-11, meaning bad airbag and possibly bad cable reel. No recalls or effort by Acura (contacted by me) to assist with fix. Replacement isn't readily available, nor is a dealer loaner. Part is $1202.75. Vehicle is 2009 with only 89,7XX miles.
Feb 09, 2022
WAS TOLD ON TODAY SHOW (NBC) THAT COULD CHECK TO SEE IF ACURA AIR BAGS NEED TO NE REPLACED EVEN THOUGH NOT AN OFFICIAL RECALL. PLEASE LET ME KNOW IF THESE AIRBAGS ARE THE ONES THAT ARE TO BE REPLACED AND IF SO, WHEN. MANY THANKS.

I HAVE A RECURRING PROBLEM WITH MY AIR BAG SYSTEM ON MY 2009 ACURA MDX (VEHICLE NO [XXX]) WHICH MY LOCAL DEALER HAS BEEN UNABLE TO RESOLVE. I FIRST NOTICED THE PROBLEM WHEN THE VEHICLE HAD APPROXIMATELY 21,000 MILES. I CONTACTED THE SERVICE DEPARTMENT AT KEARNY MESA ACURA AND INFORMED THEM THE CHECK AIR BAG LIGHT WAS COMING ON. KEARNY MESA ACURA ASKED IF IT WAS ON ALL OF THE TIME. I EXPLAINED THAT THE WARNING LIGHT WAS ON INTERMITTENTLY (SOME DAYS IT WAS ON AND SOME DAYS IT WAS OFF). THEY SAID NOT TO BRING THE CAR IN UNTIL IT IS JUST ON ALL OF THE TIME (EVERYDAY). SEVERAL MONTHS LATER IT HAD DEGRADED TO THE POINT WHERE THE LIGHT WAS ON EVERY DAY, SO I BROUGHT THE VEHICLE IN FOR SERVICE. THEY TESTED THE VEHICLE AND REPLACED APART ON THE DRIVER??S SIDE AIRBAG (PART NO 78055-STX-A10). THIS WAS AT 23,978 MILES (ON 11/9/2010). WITHIN 6 MONTHS TO A YEAR, THE LIGHT CAME ON AGAIN. AGAIN, I WAS INFORMED TO WAIT UNTIL THE LIGHT STAYED ON CONSISTENTLY (EVERYDAY). ONCE THAT OCCURRED, I BROUGHT THE CAR IN AGAIN. KEARNY MESA AGAIN TESTED THE VEHICLE AND REPLACED THE SAME PART (PART NO 78055-STX-A10). THIS WAS AT 46,511 MILES (ON 8/2/2012). ONCE AGAIN, WITHIN ABOUT 6 MONTHS TO A YEAR, THE LIGHT CAME ON. TO THIS DAY, THE PROBLEM HAS NOT BEEN RESOLVED AND ACURA WANTS TO CHARGE ME $130 DIAGNOSIS PLUS REPAIRS. I FEEL THIS IS NOT ACCEPTABLE ON SEVERAL LEVELS. FIRST OF ALL, THIS IS A RECURRING PROBLEM WHICH BEGAN WHILE THE CAR WAS UNDER WARRANTY (AND VERY EARLY IN THE LIFE OF THE VEHICLE). SECONDLY, IT APPEARS KEARNY MESA ACURA IS NOT PROPERLY DIAGNOSING/REPAIRING THE PROBLEM. IT IS POSSIBLE THAT ANOTHER COMPONENT IS CAUSING THE FAILURE OF THE PART WHICH IS BEING REPEATEDLY REPLACED (POSSIBLY WIRING ETC). I'VE ALSO TRIED WRITING TO ACURA DIRECTLY - PRESIDENT OF HONDA NORTH AMERICA. THEY SAID I WOULD JUST HAVE TO PAY FOR ANY DIAGNOSIS OR REPAIRS MYSELF.

ENGINE OIL PUMP (PREMATURE FAILURE) - I OWN A 2001 TL AND 2009MDX. ON THE MDX, I HAVE FOUND PREMATURE FAILURE OF OIL PUMP. THE VEHICLE HAS BEEN DRIVEN LESS THAN 8000 MILES PER YEAR AND FAILED AT 85000 MILES. A LEAK OVER TIME COULD RESULT IN ENGINE CEASING. ON THE TL, IT TOOK 225000 MILES TO REPLACE THE OIL PUMP.

I TOOK MY 2009 MDX INTO ACURA DEALER FOR SHUDDER AT 35-45 MPH AT 68K. SERVICE TECH WROTE UP REPAIR ORDER AS PCM UPDATE. THEY DID NOT DOCUMENT THE SHUDDER COMPLAINT. EVEN THO I DROVE WITH SERVICE TECH AND THEN HE DROVE ALSO, VERIFYING SHUDDER. I HAD TO GO BACK 2ND TIME AS PCM DIDN'T TAKE ACCORDING TO DEALER AND THAT'S WHY SHUDDERING CONTINUED AFTER 1ST PCM UPDATE. NOW AT 107K, SHUDDER IS BACK. MDX OUT OF EXTENDED WARRANTY BY 2000 MILES AND ACURA/HONDA REFUSES GOODWILL REPAIR. THIS IS MY SECOND MDX. THE TORQUE CONVERTER NEEDED REPLACED IN MY 2003 MDX. ACURA ASSURED ME WHEN I PURCHASED THE 2009 THAT THIS KNOWN PROBLEM WAS RESOLVED. OBVIOUSLY THE TORQUE CONVERTER/TRANSMISSION CONTINUES TO BE FAULTY. I'M WONDERING IF THE PCM UPDATE IS DISGUISING THE PROBLEM PUSHING THE MDX PAST THE MILEAGE WARRANTY. *TR

LOW BEAM HEADLIGHT IS EXTREMELY DIM, CAN BARELY SEE AT NIGHT. CHANGING THE LIGHT BULB DOES NOT SOLVE. HEADLIGHT COVER IS NOT FOGGY OR CLOUDY, IT IS CLEAR. SUSPECTING INTERNAL REFLECTOR ISSUE AS ACURA HAS DONE RECALLS ON OTHER MODELS FOR THE SAME ISSUE BUT NOT ON RDX.
Feb 09, 2021
MY HEADLIGHTS IN MY 2009 MDX ARE GETTING VERY FOGGY LIKE THEY TURNNIG WHITE IN OUTSIDE SURFACE IS HARD TO SEE AT NIGHT TIME WHIT THE LOW BEANS I USE THE HIGH BEANS TO BE ABLE TO SEE I TAKE IT TO A REPAIR SHOP AND THEY CANNOT DO NOTHING I THINK THIS IS A SAFETY HAZARD I SEE OTHERS ACURA WHIT THE SAME PROBLEM THEY SURE PUT THIS PROBLEM IN RECALL...THANKS

NEW CARS ARE BEING MADE WITH HEADLIGHTS WAY TOO BRIGHT, EVEN ON THE DIM SETTINGS. WHEN THE ONCOMING CAR IS ON THE SAME LEVEL AND ORIENTATION (I.E., FLAT ROAD), THE BRIGHTNESS IS NOT TOO BAD, BUT ROADS ARE NOT FLAT. THERE IS NO QUESTION ABOUT INCREASE IN BRIGHTNESS IN RECENT YEARS. IN CONNECTICUT (WHERE I LIVE), IT IS A COMMON SCENARIO TO BE ON A CORNER COMBINED WITH A SMALL ELEVATION PEAK RESULTING IN ONCOMING HEADLIGHTS POINTING DIRECTLY AT YOU. WITH NEWER CARS, THE RESULT IS MOMENTARY TOTAL BLINDNESS (LOOKING LOW AND TO THE RIGHT DOES NOT HELP). *TR

VEHICLE WAS RUNNING NORMAL. AFTER SITTING OUTSIDE ON A VERY COLD DAY IN WISCONSIN, THE CAR WOULD NOT START. IT WAS TOWED TO BERGSTROM ACURA IN APPLETON, WI WHERE A NEW STARTER WAS INSTALLED AND IT STARTED. THERE WAS AN IMMEDIATE LOUD KNOCKING NOISE. INSPECTION INDICATED A LARGE PIECE OF THE #5 PISTON BROKE OFF DUE TO A LATENT MANUFACTURING DEFECT AND DESTROYED THE ENGINE. ALTHOUGH THIS FAILURE OCCURRED IN THE SHOP, THE PISTON COULD HAVE FAILED ON THE ROAD WHICH COULD HAVE SEIZED THE ENGINE AND CAUSED AN ACCIDENT. AN IDENTICAL FAILURE WAS ALSO FOUND IN CANADA ON VIN [XXX] THAT OCCURRED JAN 12, 2015. ACURA HAS BEEN CONTACTED AND REFUSED TO CONSIDER THEM RELATED AND HAS NOT LOGGED THEM AS POTENTIAL SAFETY DEFECTS. PHOTOS OF THE FAILED PARTS ARE AVAILABLE UPON REQUEST.

ONGOING PROBLEM WITH 2009 ACURA MDX- THE CHECK ENGINE WARNING LIGHT SPORADICALLY ILLUMINATES WHILE DRIVING INDICATING THAT THE VEHICLE SHOULD BE BROUGHT TO AN ACURA REPAIR FACILITY. THE DEALERSHIP SERVICE DEPARTMENT STATED THAT IT IS A FAULTY SENSOR AND IT IS A COMMON PROBLEM WITH THE 2009 ACURA MDX. THE DEALERSHIP FURTHER STATED THAT IT WOULD BE APPROXIMATELY $700.00 FOR THEM TO MAKE THE REPAIR AS ACURA HAS NOT YET ISSUED A RECALL NOTICE FOR THE SENSOR.
May 21, 2015
THE MESSAGE CENTER CAME ON TELLING ME TO CHECK THE OIL LEVEL AND PRESSURE. PULL OVER ASAP AND HAVE IT TOWED TO NEAREST DEALER. THIS HAS HAPPENED SEVERAL TIMES NOW AND EACH TIME THEY SAY ITS A SENSOR BUT HOW MANY CAN THERE BE AND HOW CAN THEY KEEP GOING OUT. WHEN THIS IS HAPPENING THE WIPERS WILL SHORT OUT AS WELL AND RADIO WILL FADE IN AND OUT. THIS HAS TO BE A DEFECT WITHIN THE ELECTRICAL. *TR

APPROXIMATELY 3 MONTHS AGO I WENT TO START THE MEDIC AND IT WOULD NOT START. NO LIGHTS OR ANY OTHER ACCESSORIES WERE LEFT ON. THE CAR WAS JUMPED AND STARTED. BEING THE CAR WAS 4 YEARS OLD AND I HAD REVIEWS OF BATTERY PROBLEMS IN THE MEDIC, I HAD THE BATTERY REPLACED. ABOUT TWO WEEKS LATER IT WOULD NOT START AGAIN. IT WAS JUMPED AGAIN AND TAKEN TO AN AUTO REPAIR SHOP TO BE TESTED. THE REPAIR SHOP SAID THE BATTERY WAS WEAK, SO IT WAS REPLACED AGAIN. IT'S BEEN ABOUT 2 MONTHS NOW AND TODAY WHEN I WENT TO START IT, THE BATTERY WAS DEAD AGAIN. THREE BATTERIES DO NOT GO BAD THAT QUICKLY, THERE IS A PROBLEM WITH THE ELECTRICAL SYSTEM IN THIS VEHICLE. I HAVE NOTICED OTHER COMPLAINTS WITH THIS SAME ISSUE ON THIS WEB SITE. *TR

THIS VEHICLE IS ONLY 2 YEARS AND 2 MONTHS OLD (BOUGHT IN NOV. 2009), YET THE BATTERY KEEPS FAILING (AND THERE WERE NO LIGHTS LEFT ON AFTER THE ENGINE WAS SHUT OFF, AND NOTHING DONE OUT OF THE ORDINARY WITH THE CAR ON THE 3 OCCASIONS THIS WEEK THAT THE "SHUT OFF" OCCURRED). WE'VE HAD TO CALL ACURA ROADSIDE ASSISTANCE 3 TIMES THIS WEEK (WEEK OF JAN. 9TH, 2012). TODAY IS JAN. 10, 2012 AND WE HAD TO BE BOOSTED THIS MORNING AGAIN. WE EVENTUALLY TOOK IT IN TO THE MANHATTAN ACURA DEALERSHIP TODAY (1/10/12) AND WAS TOLD THAT THE BATTERY WAS, INDEED, DEFECTIVE. WE WERE ALSO INFORMED THAT OTHERS HAVE COME IN TO THAT LOCATION WITH THE SAME ISSUE (ALL ACURA OWNERS). PERHAPS, THIS SHOULD BE OFFICIALLY NOTED JUST IN CASE THERE ARE PLENTY MORE WITH THIS EXPERIENCE. *TR

MY 2009 MDX WITH 3500+ MILES HAS BEEN TAKEN TO DEALER 3 TIMES IN THE LAST MONTH. ONCE I HAD TO GET IT TOWED TO DEALERSHIP. FIRST TIME I WAS TOLD THAT THEY WAS ISSUE WITH POOR QUALITY TIMING BELT PULLEY. SO TIMING BELT GOT SHREDDED. THEY HAD TO REPLACE THE BOTH. THEY TOOK ALMOST WEEK TO REPLACE IT. WITH IN A DAY, 2009 MDX DEVELOPED ISSUE. THIS TIME THERE WAS AN ISSUE WITH CATALYTIC CONVERTER. THEY TOOK ANOTHER WEEK TO REPLACE. AGAIN WITH IN TWO DAYS, "CHECK EMISSION SYSTEM" CAME UP AGAIN. THIS TIME I WAS TOLD THEY WOULD HAVE TO REPLACE ANOTHER CATALYTIC CONVERTER AND ALSO SUB CONVERTERS. I AM REALLY CONCERNED ABOUT THE QUALITY THIS VEHICLE. *TR

AFTER 4-5 YEARS OF USAGE, THE BLUETOOTH DOESN'T WORK ANY MORE. THE ACURA DEALER SAID IT COSTS MORE THAN $600 TO BE REPLACED WITH NEW ONE. I CHECKED UP THE INTERNET, AND LOTS OF ACURA MDX OWNERS HAVE ALREADY ACKNOWLEDGED THIS PROBLEM AND LOOKING FOR A SOLUTION ON THE INTERNET. EVERYONE HAS EXACTLY SAME PROBLEM AND IT EXACTLY HAPPENED 4 -5 YEARS AFTER PURCHASE.

NOT SURE IF THIS RELATED TO TAKATA AIRBAGS. MY WIFE WAS IN BAD ROLLOVER ACCIDENT INVOLVING A 2009 ACURA MDX ON NOV 5, 2015. AT 5:15 PM ON 11/5, THURSDAY, IT WAS DARK AND RAINING AS SHE WAS HEADING EAST ON US ROUTE 12 CLOSE TO THE ARCELORMITTAL USA OFFICE AND SLIPPED, VEERED OFF THE ROAD AND SUV ROLLED OVER AND CART WHEELED AND FELL IN A DITCH. THE SUV WAS UPSIDE DOWN WHEN I ARRIVED AFTER A FIRST RESPONDER CALLED ME FROM THE SCENE. NOT SURE WHY SHE VEERED OFF WHEN SHE WAS ON THE LEFT MOST LANE. SHE SUDDENLY CROSSED 2 LANES AND SHOULDER AND ENDED UP IN A DITCH. SHE WAS NOT FATIGUED SINCE IT WAS LESS THAN 3 MIN SINCE SHE LEFT FROM THE OFFICE AND WE HAVE BLUE TOOTH HANDSFREE IN OUR 2009 ACURA MDX TECH. NOT SURE IF THE AIR BAG WENT OFF FALSELY OR IF SHE HAD A TIRE BURST. I KNOW BOTH FRONT TIRES WERE FLAT WHEN I SAW IT IN THE SALVAGE YARD. ALL SHE RECALLS IS AIR BAGS GOING OFF - NOT SURE IF THEY DEPLOYED BEFORE OR AFTER SHE HIT THE DITCH...

THERE MUST BE A DEFECT IN MY 2009 ACURA MDX HEAD RESTRAINT SYSTEM. I BELIEVE IT HAS RESULTED IN OR CONTRIBUTED TO A NECK INJURY . I HAVE HAD NECK PAIN BAD ENOUGH TO REQUIRE FOUR MONTHS OF PHYSICAL THERAPY AND FIVE SURGICAL PROCEDURES. THE HEAD REST FORCES MY NECK AND HEAD INTO AN UNNATURAL FORWARD POSITION. THE HEAD REST ONLY MOVES UP AND DOWN AND NOT FORWARD AND BACK. I AM UNABLE TO ADJUST THE SEAT AND STEERING WHEEL TO ACCOMMODATE FOR THE LACK OF ADJUSTABLE IN THE HEAD REST. *TR

I PURCHASED AN ACURA CERTIFIED 2009 MDX BASE WITH BRIDGESTONE DUELER H/L 400 TIRES ON IT. THE QUALITY OF BRIDGESTONE TIRES WERE UNACCEPTABLE. THESE TIRES HAD NO GRIP ON WET ROAD AND ROAD COVERED WITH LIGHT SNOW. THERE WERE MULTIPLE CASES WHEN MY ALL WHEEL DRIVE SKIDDED ON THE HIGHWAY DURING LANE CHANGE. DUE TO SAFETY CONCERNS, I HAD TO REPLACE ALL FOUR TIRES WITHIN A FEW MONTHS OF PURCHASING THE VEHICLE. ACURA SHOULD NOT USE BRIDGESTONE TIRES IN ITS VEHICLES. ALSO, FIRESTONE/BRIDGESTONE SHOULD RECALL THESE TIRES AND REFUND MONEY FOR THE REPLACEMENT COST OF MY TIRES. WILL APPRECIATE IF YOU PLEASE LOOK INTO THIS ISSUE. *JS

I BROUGHT THE CAR INTO THE DEALER BECAUSE I WAS HAVING TRANSMISSION PROBLEMS OR POWER STEERING PROBLEMS. I INDICATED THAT THE CAR MAKES A WHINE AT ABOUT 1500 RPM. THE DEALER CHOSE TO TREAT IT AS A POWER STEERING PROBLEM. THE POWER STEERING PUMP WAS REPLACED. THERE WAS STILL A WHINE ALTHOUGH LESS. THE CAR RPM HANGS UP ON DECELERATION TO A STOP. SOME TIMES WHEN GOING DOWN HILL THE CAR DOES NOT UPSHIFT UNTIL THE CAR IS ACCELERATED EVEN THOUGH THE ROAD SLOPE IS ZERO. THE DEALER NEVER INFORMED ME WHEN I BROUGHT THE VEHICLE IN FOR THE ORIGINAL CONCERN THAT THERE WERE SOME PROBLEMS WITH THE TRANSMISSION OR TORQUE CONVERTER HANGING UP. *TR

ACURA MDX (2009) VIBRATION ISSUES: SINCE PURCHASING THE VEHICLE NEW, THERE IS A VIBRATION DRIVING AT SPEEDS EXCEEDING 70 MPH. THE VIBRATION CAN BE FELT THROUGH THE CHASIS AND STEERING WHEEL. THE DEALER HAS REPLACED THE TIRES, RIMS, DRIVE SHAFT AND PERFORMED MULTIPLE BALANCING AND ALIGNMENTS. THE MANUFACTURER REPRESENTATIVE COULD NOT RESOLVE THE ISSUE INITIALLY, BUT LATER SUGGESTED THE REPLACEMENT OF THE DRIVE SHAFT. THIS WORKED INITIALLY BUT THE PROBLEM HAS RESURFACED AGAIN. I FILED A LEMON LAW CLAIM THAT ACURA HAS NEGLECTED TO RESPOND TO FULLY. THEY TRIED TO FIX IT, BUT THE PROBLEM IS STILL PRESENT AND GETTING WORSE. WHEN DRIVING THE CAR, IT FEELS AT TIMES, AS IF THE WHEELS ARE GOING TO FALL OFF. IT IS OFTEN WORSE WHEN DRIVING UP HILL WHEN THE CAR IS COLD AND THE WEATHER COLD. IT APPEARS TO GET BETTER AS THE CAR WARMS UP, THOUGH. THIS ALSO APPEARS TO BE A WELL DOCUMENTED CONCERN THAT IS DOCUMENTED ON DISCUSSION BOARDS SUCH AS: EDMONDS- HTTP://TOWNHALL-TALK.EDMUNDS.COM/WEBX/.F13BAE6?DISPLAYRECENT WHERE THERE ARE CURRENTLY 59 POSTS ON THE TOPIC AND ALL SIMILAR TO MY EXPERIENCE. *TR
