Odometer Fraud. The contact purchased a 2009 Acura MDX. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of the purchase, the mileage was 117,500. At the time of the vehicle registration, it was discovered that the mileage was 140,223.
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..
I just got this car in September and it is now throwing all kinds of different codes to the point where I can’t drive it sh-awd /check charging station / emission light etc
While driving vehicle, all power shut off after all lights(airbag, tire, engine, etc. came on the dashboard) not able to start vehicle now at all. Has power but will not run, turn over, stay running, etc. has brand new battery so that’s not the problem no problems until today.
I was driving onto an exit ramp around 50 to 60 mph on Rt 50 yo 495 south and VSA light appeared on dash. Also steering felt extremely loose. No control to steer and could not accelerate either.
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.
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.
The contact owns a 2009 Acura MDX. The contact stated while driving at an undisclosed speed and approaching a stop sign, the accelerator pedal was depressed however, the vehicle failed to respond. The contact shifted the vehicle to neutral and back to drive and the vehicle responded slowly. The failure recurred several times. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was 150,061.
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.

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
ON JUNE 30TH 2019 AFTER LEAVING FROM WORK I WAS ON MY WAY TO PIER 1 WHICH IS APPROXIMATELY 2 MILES AWAY. I TURNED INTO THE PARKING LOT PARKED IN FRONT OF PIER 1 AND ALL OF A SUDDEN MY CAR ACCELERATED OUT OF CONTROL. IT JUMPED THE CURB CRASHED THROUGH PIER 1 WINDOW INTO THE STORE AND DIDN'T STOP UNTIL IT HIT A WALL. AT THIS TIME I'M IN SHOCK GLASS IS EVERY WHERE AND I COULD MOVE I HEAR PEOPLE IN THE BACKGROUND TELLING ME TO GET OUT OF THE CAR BUT I WAS FROZEN FROM WHAT JUST HAPPENED. I JUST WANT TO HOLD ACURA ACCOUNTABLE BECAUSE I SEE THIS HAS HAPPENED TO SEVERAL PEOPLE
ALL DOOR LOCKS, WINDOWS, TRUNK, FUEL DOOR, AND SUNROOF DOES NOT WORK
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.
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.

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.
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.
BLUETOOTH STOPPED WORKING AND A FEW WEEKS LATER, MY CAR WOULDN'T START. I REPLACED THE BATTERY AND A FEW DAYS LATER THE CAR STALLED ON ME AS I WAS PULLING OUT OF MY SPOT!!!!! I WENT TO THE ACURA DEALER AND EXPLAINED TO THE GUY THAT MY BATTERY KEPT DRAINING. HE ASKED ME IF MY BLUETOOTH STOPPED WORKING, I WAS SHOCKED BECAUSE I HADN'T MENTIONED ANY ISSUES WITH MY BLUETOOTH BUT I LET HIM KNOW THAT IN FACT, THE BLUETOOTH HAD STOPPED. THE REP SAID IT'S A COMMON PROBLEM IN MY VEHICLE. HAD TO REPLACE THE BLUETOOTH AND PAID $600!!!! MY FRIENDS SISTER HAS THE SAME MAKE CAR AND HER BLUETOOTH STOPPED WORKING AND HER CAR BATTERY KEEPS GOING DEAD. IT'S VERY SCARY SINCE APPARENTLY I MUST HAVE STARTED THE CAR RIGHT BEFORE THE BATTERY DIED AGAIN. IMAGINE WHAT WOULD'VE HAPPENED IF IT HAD STALLED ON A HIGHWAY OR A BUSY STREET!

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
