2016 Acura MDX Complaint Log

I RECENTLY BOUGH THE CAR AND I AM NOW REGRETTING IT BECAUSE THE 9 SPEED TRANSMISSION IS VERY SLUGGISH AND DOESN'T PROVIDE POWER WHEN NEEDED. IN THE MORNING WHEN I START THE CAR THE CAR JUST LAGS THE POWER UNTIL I PRESS HARD ON THE GAS PEDAL. WE TOOK THIS ON A ROAD TRIP TO CALIFORNIA FROM UTAH AND AT TIMES I FEEL LIKE I DON'T HAVE AMPLE POWER TO PASS OTHER DRIVERS AND IT TAKES A FEW SECONDS TO THINK BEFORE IT DOES ANYTHING. I HAVE AN APPT SCHEDULED WITH ACURA TOMORROW TO SEE WHAT CAN BE DONE TO FIX THIS OTHERWISE I AM TAKING THIS SUV BACK TO THE DEALER FOR ANOTHER CAR. I AM VERY DISAPPOINTED WITH ACURA FOR MAKING THIS KIND OF A TRANSMISSION AND I WISH I HAVE KEPT MY BMW.

TL* THE CONTACT OWNS A 2016 ACURA MDX. THE CONTACT STATED THAT WHILE DRIVING AT 75 MPH, THE VEHICLE INDEPENDENTLY SHIFTED INTO NEUTRAL. THE FAILURE RECURRED SEVERAL TIMES AND THE CONTACT WAS UNABLE TO SHIFT THE VEHICLE BACK INTO DRIVE. THE CONTACT PULLED OVER AND RESTARTED THE VEHICLE AND THE VEHICLE OPERATED AS INTENDED. THE CONTACT STATED THAT THE POWER TRAIN CONTROL MODULE SOFTWARE WAS PREVIOUSLY UPDATED AT ROSENTHAL ACURA (623 FREDERICK AVENUE, GAITHERSBURG, MD 20879, (877)300-4226) HOWEVER, FAILED TO PREVENT THE FAILURE. THE VEHICLE WAS TAKEN BACK TO THE SAME DEALER TO BE INSPECTED. THE CONTACT REFERENCED MANUFACTURER COMMUNICATION NUMBERS: 15-034 NAD 19-003 AS POSSIBLE FIXES FOR THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 39,000. *LN *TR

WHILE BACKING OUT OF A RESTAURANT LOT PARKING SPACE ON A WET RAINY NIGHT, APPLIED BRAKES REPEATEDLY AND CAR WOULD NOT STOP RESULTING IN HITTING A PARKED CAR IN THE LOT. IMMEDIATELY NOTIFIED MY INSURANCE CO. SAME TYPE OF PROBLEM HAPPENED A YEAR AND HALF AGO. HAVE NOTIFIED ACURA TO CORRECT PROBLEM. INTEND TO TRADE CAR BECAUSE OF CONCERN..

TL* THE CONTACT OWNS A 2016 ACURA MDX. THE CONTACT STATED WHILE DRIVING 20 MPH, WHEN DRIVING OVER A SPEED BUMP THE VEHICLE ACCELERATED INDEPENDENTLY AND IMPACTED THE VEHICLE IN FRONT. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. AIR BAGS DID NOT DEPLOY. THE CONTACT STATED SHE WAS NOT INJURED. THE CONTACT STATED THE DRIVER OF THE OTHER VEHICLE SUSTAINED UNKNOWN INJURIES BUT WAS NOT AWARE IF MEDICAL ATTENTION WAS REQUIRED. A POLICE REPORT WAS FILED. THE VEHICLE WAS NOT DRIVABLE AND WAS TOWED TO AN INDEPENDENT COLLISION CENTER. THE VEHICLE FAILURE WAS NOT DIAGNOSED BY AN INDEPENDENT MECHANIC OR DEALER. THE CONTACT ALSO MENTIONED AFTER THE ACCIDENT THE VEHICLE WAS SERVICED UNDER NHTSA CAMPAIGN NUMBER: 19V060000 (FUEL SYSTEM, OTHER) AT NORRIS ACURA (8559 BALTIMORE NATIONAL PIKE, ELLICOTT CITY, MD 21043) ON 10/11/2019. THE CONTACT STATED AFTER THE RECALL REMEDY THE VEHICLE HAD A FUEL LEAK. THE DEALER WAS CONTACTED, HOWEVER STATED SHE WOULD BE REASONABLE FOR DIAGNOSES AND REPAIRS FEES. THE MANUFACTURER HAD NOT BEEN INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 64,053.

TL* THE CONTACT OWNS A 2016 ACURA MDX. THE CONTACT STATED THAT SIDEWALLS OF THE SPARE TIRE, WHICH WAS STORED UNDERNEATH THE VEHICLE, WAS WEARING THROUGH AT THREE DIFFERENT LOCATIONS. THE TIRE WAS TAKEN TO MCDANIELS ACURA OF CHARLESTON (2283 SAVANNAH HWY, CHARLESTON, SC 29414, (843) 766-1299) AND THE CONTACT WAS INFORMED NOT TO WORRY. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 20,000.

CAR ELECTRICAL ACTIVATED WHEN START BUTTON WAS PUSHED BUT IT WASN'T CLEAR IF ENGINE WAS RUNNING. CAR WOULD NOT "TURN OFF" OR LOCK. MANY ERROR MESSAGES CAME ACROSS DASH AND CAR WAS NOT PROPERLY RECOGNIZING FOBS. AN ACURA SERVICE CENTER WAS CALLED AND WE WERE TOLD OUR ONLY OPTION WAS TO DISCONNECT BATTERY LEADS OR LET THE CAR RUN UNTIL THE BATTERY DIED. MANY HOURS LATER THE BATTERY DIED. WHEN THE ACURA SERVICE TRUCK CAME TO GET US THEY COULDN'T EVEN GET THE CAR INTO NEUTRAL AFTER CHARGING THE BATTERY AND WHEEL TRUCK HAD TO BE CALLED. THE DEALERSHIP HAD THE CAR FOR WEEKS AND WAS NOT ABLE TO DETERMINE THE PAUSE. WE HAVE MULTIPLE VIDEOS OF THE INCIDENT. NOTE THAT THE CAR WAS NOT IN ACCESSORY MODE AND THE BEHAVIOR IS INCONSISTENT WITH ACCESSORY MODE.

THE LETTERS ON THE SHIFTING CONTROLS ARE WEARING OFF WITH NORMAL USE CREATING AN UNSAFE CONDITION AS IT IS BECOMING UNCLEAR WHICH SHIFT BUTTONS PUT THE VEHICLE IN PARK. THIS HAS OCCURRED ON BOTH MY 2016 HONDA VEHICLES. HONDA HAS ACKNOWLEDGED THIS ISSUE BUT ONLY OFFERS TO PAY ONE HALF OF THE COST OF CORRECTING THIS DANGEROUS ISSUE.

WHILE IN MOTION, FIRST BRAKELIGHT HAD WARNING THEN WARNING ABOUT TRAILER STABILITY ASSIST. WHEN I WENT IN REVERSE, THE WHOLE DASHBOARD INCLUDING THE NAVIGATION SCREEN WENT BLACK AND THE CAR FELT LIKE THE ENGINE STOPPED. THIS HAPPENED A FEW TIMES. I DON'T THINK THE ENGINE ACTUALLY STOPPED THOUGH BECAUSE I DID NOT HAVE TO RESTART THE CAR. THE BRAKE LIGHT ERROR MESSAGE HAS OCCURRED DRIVING FORWARD AS WELL, BUT NOT ACCOMPANIED BY THE BLACKOUT OF THE DASH AND NAV PANEL. ALL OF THIS HAPPENED WHILE IN MOTION. THE WORST OF THIS HAPPENED ON 07/30/2018 BUT VARIATIONS OF THIS OCCURRED PRIOR TO THAT.

WHEN DRIVING AROUND 75 MPH ON THE INTERSTATE I WENT TO SWITCH LANES AND WHEN PRESSING THE ACCELERATOR NOTHING HAPPENED AND ACCELERATION WAS NOT POSSIBLE. ALL WARNING LIGHTS CAME ON, INCLUDING ALL WHEEL DRIVE SYSTEM PROBLEM, EMISSION SYSTEM PROBLEM, ALL WHEEL DRIVE SYSTEM PROBLEM, TRANSMISSION SYSTEM PROBLEM. CHECK ENGINE AND SH-AWD. THE POWER STEERING AND BRAKES STILL WORKED AND WAS EXTREMELY LUCKY TO GET THE CAR TO THE SHOULDER WITHOUT GETTING INJURED OR KILLED. HAD CAR TOWED TO CHATTANOOGA ACURA DEALER. CAR WAS OPERATING NORMALLY WHEN THEY RECEIVED IT. ACURA TECH SUPPORT ADVISED DEALER TO REPLACE TRANSMISSION AND TRANSMISSION CONTROL MODULE (TCM). ALSO WAS TOLD ACURA IS WORKING ON A SOFTWARE UPDATE FOR THE TCM BUT IT IS NOT AVAILABLE YET BUT I HAVE LITTLE CONFIDENCE IN THE FIX AND LITTLE CONFIDENCE THAT THIS WON'T REOCCUR. STRONGLY CONSIDERING REPLACING THE CAR

9 SPEED TRANSMISSION LURCHES FORWARD WHEN TRYING TO STOP - SENDING THE CAR FORWARD WHILE TRYING TO BRAKE. HAPPENS WHEN THE CAR SHOULD SHIFT BETWEEN GEARS 3-2 AND 1-2/2-1. ACURA DEALERSHIP SAID IT'S THE FUEL SAVER ONCE, NORMAL THE SECOND TIME, AND UPDATED THE TCM/PCM ANOTHER. THERE IS NO ONE ADDRESSING THIS WHEN IT COULD SEND MY CAR INTO ANOTHER CAR WHEN TRYING TO STOP. THE LAST TIME I DROVE IT ON SUNDAY 7/15 I WAS SLOWING DOWN TO TURN INTO A SHOPPING CENTER, GOING AROUND 20MPH WHEN THE CAR JERKED FORWARD, SNAPPING MY NECK FORWARD 12"-14" THEN BACK AGAIN. THE CAR IS AT THE DEALERSHIP NOW WITH THE SERVICE ADVISER SAYING THE LURCHING IS THE FUEL SAVER AND THAT ACURA WON'T PAY FOR A WARRANTIED ITEM UNLESS THE SERVICE LIGHT/CODES ARE THERE.

The contact owns a 2016 Acura MDX. The contact stated while driving at various speeds, the vehicle would stall. The contact also stated that the vehicle would jerk when the accelerator pedal was depressed. The contact stated the information and engine warning lights were illuminated on the control panel. The vehicle was taken to a local dealer where it was diagnosed with the transmission needing to be updated. The vehicle was repaired but the failure still occurred. The contact was relating the failure to NHTSA campaign number: 19V060000 (Fuel System, Other). The manufacturer had been informed of the failure and the contact filed a claim. The failure mileage was approximately 41,000.

SINCE WE PURCHASED THIS CAR WE HAVE ISSUES WITH THE VEHICLE WHERE IT IS HESITATING TO ACCELERATE WHEN GOING FROM 0 MPH TO 30 MPH. WE TOOK IT TO THE DEALERSHIP AND THEY UPDATED THE SOFTWARE FOR THE POWERTRAIN BUT STILL THE VEHICLE HAS ACCELERATION ISSUES WHEN GOING FROM 0 TO 40 MILES PER HOUR. WE HAVE RESEARCHED THIS ISSUE ON INTERNET AND IT SEEMS LIKE LOTS OF PEOPLE OWNING ACURA ARE HAVING THIS ISSUE. THIS ISSUE IS ATTRIBUTED TO NEW 7 SPEED TRANSMISSION THAT ACURA BUILT. IT LOOKS LIKE A SAFTEY ISSUE SINCE THE VEHICLE WOULD NOT ACCELERATE AFTER STOPPING AT TRAFFIC LIGHT OR STOPPING TO TAKE RIGHT AND RE ACCELERATING.

THE TRANSMISSION SHIFT VERY HARD AND WHEN I RELEASE THE GAS PEDAL THE CAR STAR TO BRAKE AND ACCELERATE BY HIM SELF AND IT'S DANGER AND ANNOYING

JUNE 10, 2018 - 4 HOURS INTO 5.5 HOUR TRIP, TRAVELING ON HWY 98, SOUTH OF TALLAHASSEE, FL, VEHICLE LOST ACCELERATION, SERIES OF WARNING LIGHTS STARTED FLASHING. LIMPED OVER ONTO SHOULDER, TURNED VEHICLE OFF, CALLED ROADSIDE ASSISTANCE. WHEN TOW TRUCK ARRIVED AN HOUR LATER, STARTED VEHICLE AND IT RAN NORMALLY....DROVE VEHICLE TO PROCTOR ACURA, FOLLOWING TOW TRUCK. DEALERSHIP AND FACTORY PERSONNEL UNABLE TO DETERMINE PROBLEM. DECEMBER 4, 2018 - 1 HOUR INTO 3 HOUR TRIP, WIFE TRAVELING ALONE ON INTERSTATE 10E, MOBILE, AL. WHILE ON BRIDGE ACROSS MOBILE BAY, VEHICLE LOST ACCELERATION. AS SHE WAS COASTING ONTO NARROW SHOULDER, FRANTICALLY PUMPING ACCELERATOR, VEHICLE RE-ENGAGED AND TRIP WAS COMPLETED WITH NO FURTHER ISSUE. UNSURE IF WARNING LIGHTS CAME ON. MARCH 8, 2019 - 3.5 HOURS INTO 5 HOUR TRIP, TRAVELING ON HWY 49N, BETWEEN HATTIESBURG AND COLLINS, MS. VARIOUS WARNING LIGHTS CAME ON, EMERGENCY FLASHERS CAME ON BY ITSELF, VEHICLE NEVER LOST ACCELERATION. PULLED OVER ONTO SHOULDER, LEFT ENGINE RUNNING, AND THEN DROVE APPX 5 MILES TO A SONIC DRIVE-IN. TURNED VEHICLE OFF, LET IT SIT FOR A FEW MINUTES, CALLED ACURA CUSTOMER SERVICE AND WAS ASSIGNED A CASE #. RESTARTED ENGINE, EMERGENCY FLASHERS NO LONGER ON, OTHER WARNING LIGHTS STILL FLASHING AND DROVE TO DESTINATION. STARTED TRIP BACK HOME THE NEXT DAY, WARNING LIGHTS REMAINED ON UNTIL A THIRD OF THE WAY, THEN THOSE LIGHTS WENT OFF. TOOK VEHICLE TO TIM SMITH ACURA, FT. WALTON BEACH, FL. MET WITH DEALERSHIP SERVICE MANAGER, WHO EXPLAINED DIAGNOSIS AND REPAIRS MADE, BUT WOULD PROVIDE NO ASSURANCE WHATSOEVER PROBLEMS WOULD NOT REOCCUR. ALSO MENTIONED HE JUST RECEIVED AN EMAIL FROM FACTORY THAT A POSSIBLE FIX WAS AT HAND BUT WOULD BE A FEW WEEKS AWAY. NOTES: * PROBLEMS OCCUR ONLY DURING A ROAD TRIP * VEHICLE FIXES ITSELF EVERY TIME * VEHICLE IS UNSAFE & UNRELIABLE * EMAILED AM HONDA, NO REPLY

ACURA IS REFUSING TO ADDRESS A SERIOUS PROBLEM WITH THE ENGINE AND POWER TRAIN WITH THE VEHICLE, THIS MAY HAVE ALREADY CAUSED ACCIDENTS ON OTHER CARS IN OTHER STATES. PLEASE SEE THE HISTORICAL DATA WHICH GIVES A COMPLETE AUDIT OF THE ISSUES I HAVE HAD. 9/22/18 11 DAYS- VEHICLE TAKEN TO THE DEALER AND DROPPED FOR SERVICE, PUNCH LIST OF ISSUES SINCE PURCHASE THAT NEEDED ADDRESSED. ALIGNMENT REPORT IS SIGNED OFF ON 9/24/18, BATTERY CHECK 10/1/18, SERVICE WAS STARTED ON 9/29/18, CAR SAT FOR A WEEK WITH NO SERVICE ATTEMPT MADE. OIL STAINS ON ROOF LINER WERE LEFT THERE AND WAS TOLD THEY WOULD NOT CLEAN THEM OFF (LATER PROVEN TO BE MECHANICS GREASE BY MERRILLVILLE) AND SPIDER WAS MY PROBLEM NOT THERES PER 'ROB' IN SERVICE. ISSUES THE CAR WAS TAKEN IN FOR. ALL OF THE BELOW SERVICE WAS COMLETED IN 5 MILES ACCORDING TO ODOMETER READINGS. ON 10/12/18 I TOOK THE VEHICLE TO ACURA OF MERRILLVILLE PER 'ANTHONY' FROM ACURA CLIENT CARE TO HAVE IT CHECKED. I DROVE IT WITH THE TECH AND THE TECH WAS ABLE TO VALIDATE A LOT OF THE ISSUES RIGHT AWAY. IT WAS RETURNED TO ME ON 11/2/18 22 DAYS ON 11/24/18 I RETURNED THE VEHICLE TO ACURA OF MERRILLVILLE DUE TO THE TRANSMISSION ISSUE RETURNING, ALSO ADDRESSED A COUPLE OF ISSUES. CAR RETURNED ON 11/28/18 4 DAYS VEHICLE LOSES POWER WHEN SHIFTING TO ACCELERATE, OFTEN HAVE TO DOWNSHIFT USING PADDLE SHIFTERS TO MAKE POWER OR CAR ACTS LIKE ITS GOING TO STALL. BRAKES DO NOT FUNCTION UNILATERALLY, HIT THE BRAKES HEAVY WHILE IN TRAFFIC AND THE BACK WILL BEGIN TO COME AROUND AS THOUGH ONE OF THEM DOES NOT GRAB. ENGINE LOSES POWER WHEN IN TRAFFIC IT STRUGGLES TO ACCELERATE WHICH COULD CAUSE A CRASH IF NEEDING POWER TO ACCELERATE ONTO A EXPRESSWAY FROM AN ENTRANCE RAMP, OR ANYWHERE THAT REQUIRES POWER TO MOVE THE CAR.

THE CAR OVERHEATED AND WAS LEAKING BLUE FLUID, STARTED SMOKING AND HAD A WEIRD CHIRPING NOISE COMING FROM THE ENGINE. THE CAR WAS PARKED AND WAS JUMPING ANOTHER CAR WITH A DEAD BATTERY.

I purchased the vehicle in 2017. It was certified used by acura dealer but it was practically new; less than a year old with 10,000 miles on it. About a month or so after purchasing I started noticing a an issue when pressing on the gas and the vehicle not responding and a few seconds later it would suddenly jerk trying to catch up to the gear it should be on. Right away I took it to dealership for them to inspect and they said the vehicle needed a "software update" and it should be fine after that. Long story short, it is now 2025 I've taken the vehicle in for a "software update" more times than I can count and I am still living with the same problem. On occasion it gets better and sometimes it gets worse. Especially at higher speeds when the gears seem to go to neutral for a few seconds and then re-engage again on its own which cause jerking/stalling motion.

WHILE DRIVING OR PARKED THE "TRANSMISSION SYSTEM PROBLEM" ILLUMINATED ON THE DASHBOARD. THE "D" LIGHT ALSO BEGAN FLASHING ON CONSOLE AND THEN CAR GOES INTO NEUTRAL BY ITSELF. IN ADDITION ANOTHER WARNING LIGHT CAME ON THE DASHBOARD THAT SAID "BLIND SPOT WARNING MALFUNCTION" FOLLOWED BY 3RD MESSAGE THAT SAID "TRANSMISSION SYSTEM PROBLEM" AND D LIGHT DISAPPEARS FROM DASHBOARD . WHEN DRIVING, THE CAR CONTINUES AT SAME RATE SPEED THANKFULLY. WHEN PARKED, CANNOT PUT VEHICLE IN PARK AND HAVE TO USE EMERGENCY BRAKE. WHEN THIS HAPPENS THE CAR CANNOT BE LOCKED SINCE IT RECOGNIZES CAR IN DRIVE. TAKING TO DEALERSHIP TOMORROW. I DON'T LIKE DRIVING THE CAR SINCE I'M CONCERNED IT WILL GO INTO NEUTRAL AS I'M DRIVING. I BELIEVE THIS COULD BECOME A SIGNIFICANT SAFETY ISSUE FOR MYSELF AND OTHER DRIVERS AT RISK. ANY TIME A CAR DOES THIS WITHOUT EXPLANATION ON THE HIGHWAY WARRANTS AN INVESTIGATION.

WHILE ACCELERATING AND SWITCHING LANES ON THE INTERSTATE AROUND 70MPH THE CAR REDUCED POWER AND THEN DOWNSHIFTED AND REVVED UP TO OVER 4K RPMS. THE CAR WOULD NOT ACCELERATE WITH FOOT ALL THE WAY INTO IT AND REDUCED SPEED TO 50MPH. EMISSIONS SYSTEM ERROR, TRANSMISSION PROBLEM ERROR, SH AWD ERROR AND BLIND SPOT ASSIST ERROR WERE ALL ILLUMINATED.

TL* THE CONTACT OWNS A 2016 ACURA MDX. WHILE DRIVING 72 MPH WITH THE CRUISE CONTROL ACTIVATED, THE VEHICLE LURCHED TWICE AND ALL THE WARNING INDICATORS ILLUMINATED, DISPLAYING TRANSMISSION SYSTEM FAILURE, FUEL EMISSION FAILURE, AND LANE DEPARTURE FAILURE. THE VEHICLE STALLED AND WAS COASTED TO THE SIDE OF THE ROAD. THE CONTACT ATTEMPTED TO RESTART THE VEHICLE, BUT WAS UNSUCCESSFUL. THE VEHICLE WAS TOWED TO AN ACURA DEALER (ACURA OF JACKSON, 828 ADCOCK ST, RIDGELAND, MS 39157) WHERE IT WAS DETERMINED THAT THERE WAS A COMPUTER GLITCH. THE COMPUTER SYSTEM WAS RESET. THE DEALER STATED THAT THIS WAS A KNOWN FAILURE WITH ACURA AND NO PERMANENT REMEDY WAS UNAVAILABLE. THE DEALER ALSO STATED THAT THE FAILURE COULD RECUR IN 10 TO 10,000 MILES. THE CONTACT WAS CONCERNED THAT THE FAILURE WOULD RECUR AND TOOK THE VEHICLE TO DAVID MCDAVID ACURA OF AUSTIN (13553 RESEARCH BLVD, AUSTIN, TX 78750). THE CONTACT INFORMED THE DEALER THAT SHE FELT UNSAFE DRIVING THE VEHICLE AND WANTED TO TRADE IT IN FOR ANOTHER VEHICLE. THE MANUFACTURER WAS NOTIFIED AND ADVISED THE DEALER TO ATTEMPT TO DUPLICATE THE FAILURE. THE VEHICLE WAS CURRENTLY AT THE DEALER AWAITING A NEW DIAGNOSIS AND POSSIBLE REPAIRS. THE FAILURE MILEAGE WAS UNKNOWN.

THERE WERE A NUMBER OF INCIDENTS PRIOR TO 16 FEBRUARY 2018 WHERE THE CARE JERKED WHILE COMING TO A STOP AND HESITATED ON ACCELERATION POSSIBLY RELATED TO TRANSMISSION MISSHIFTING. WE TOOK OUR CAR INTO AN ACURA DEALER ON 16 FEBRUARY 2018 BUT THE ISSUE WAS NOT RESOLVED.

IN DIFFERENT SETTINGS I HAVE EXPERIENCED A LAG OR HESITATION WHEN I PRESS THE ACCELERATOR. THE HESITATION IS SUFFICIENT THAT IT MAKES IT DANGEROUS TO SHIFT LANES AT HIGHWAY SPEEDS AS WELL AS TO TURN LEFT AT A STOP SIGN ON A LOCAL STREET. I HAVE DISENGAGED THE AUTO-IDLE FEATURE TO MINIMIZE THE ISSUE AT STOP SIGNS AND I AM NOW DRIVING IN SPORTS MODE 100% OF THE TIME BECAUSE THIS MINIMIZES THE HESITATION; HOWEVER, IT IS NECESSARY TO "GUN" THE ENGINE TO ENSURE THAT THE HESITATION DOES NOT RESULT IN A MAJOR ACCIDENT. I HAVE DISCUSSED THE ISSUE WITH THE ACURA SERVICE DEPARTMENT EACH TIME I HAVE BROUGHT MY CAR IN FOR AN OIL CHANGE OVER THE PAST 1.5 YEARS, AND THEY DENY THAT THERE IS AN ISSUE WITH THE POWER TRAIN. I DO NOT ALLOW OTHER MEMBERS OF MY FAMILY TO DRIVE MY MDX AS I FEAR THEIR INEXPERIENCE WITH THE TRANSMISSION PROBLEM WILL RESULT IN A MAJOR CAR ACCIDENT.

WHILE DRIVING ON THE HIGHWAY THE "TRANSMISSION SYSTEM PROBLEM" ILLUMINATED ON THE DASH BOARD. THE "D" LIGHT ALSO BEGAN FLASHING. IN ADDITION ANOTHER WARNING LIGHT CAME ON THAT SAID "BLIND SPOT WARNING MALFUNCTION". THE CAR SLOWED DOWN. IT WOULD NOT GO FASTER THAN 15-20 MPH ON THE HIGHWAY WHILE THE RPM'S SURGED TO OVER 4,000 RPM. THE CAR HAD TO BE TOWED TO THE DEALERSHIP YESTERDAY. AS OF TODAY THEY STILL HAVE NOT BEEN ABLE TO IDENTIFY WHY THIS HAPPENED. I BELIEVE THIS IS A SIGNIFICANT SAFETY ISSUE THAT PUT MYSELF AND OTHER DRIVERS AT RISK. ANY TIME A CAR DOES THIS WITHOUT EXPLANATION ON THE HIGHWAY WARRANTS AN INVESTIGATION.

THE CAR RPMS DO NOT KEEP UP WITH THE SPEED. WHEN DECELERATING IN TRAFFIC RPMS REMAIN HIGH AND THE CAR SURGES FORWARD. GOING DOWN HILLS WHEN TAKING FOOT OFF THE BRAKE THE CAR SURGES FORWARD. WHEN SITTING AT A STOP SIGN AND STARTING AGAIN THE CAR WOULD SURGE FORWARD. THE ENGINE IS VERY ERRATIC AND THE SOFTWARE UPDATES DO NOT REMEDY THE SITUATION. VERY SCARY DRIVING THE CAR. COLD WEATHER MAKES THE SYMPTOMS WORSE. NEED TO WARM UP THE CAR A MINIMUM OF FIVE MINUTES. IT IS VERY SLUGGISH IN THE COLD AND THE SURGING IS MORE PROMINENT. NOT GOOD IF YOU LIVE IN COLD CLIMATES. I NEED TO DRIVE THROUGH A RESIDENTIAL AREA OF A CITY WITH CHILDREN CROSSING THE STREET. I AM AFRAID IF THE CAR SURGES WHEN I BREAK THERE MAY BE AN ACCIDENT WITH A PEDESTRIAN OR I MAY REAR END THE CAR IN FRONT OF ME. I HAVE ANOTHER APPOINTMENT WITH THE DEALER TO ADDRESS THE PROBLEM. LOOKING TO TRADE IN THE VEHICLE WITH A DIFFERENT TRANSMISSION. THIS VEHICLE SHOULD NEVER BE RESOLD!

PROBLEM: ON JANUARY 06 2018 MILEAGE (49,930) WHILE DRIVING 60-68 MPH FOR APPROXIMATELY 20MINUTES BETWEEN INDIANAPOLIS AND MARTINSVILLE IN, I ATTEMPTED TO ACCELERATE, MOVE TO THE LEFT LAND AND PASS. I PRESSED THE ACCELERATOR AND THAT WHEN THE PROBLEM OCCURRED: 1)THE CAR WOULDN'T ACCELERATE, 2)THE 'D' LIGHT BEGIN FLASHING 3)WOULD NOT SHIFT, EVEN USING PADDLES 4)TRANSMISSION 'MALFUNCTION' LIGHT 5)TACHOMETER WAS AT APPROXIMATELY 4500 RPM @50 MPH 6)EMISSIONS LIGHT STARTED FLASHING 7)YELLOW ENGINE ICON WAS ON, 8)BLIND SPOT NOT WORKING INDICATOR WAS ON. I MADE IT TO A PARKING LOT, TURNED THE CAR OFF, WENT INTO A STORE FOR LESS THAN 10 MINUTES, AND RESTARTED THE CAR. ITEMS 1-5 AND 8 WERE NO LONGER FLASHING, AND THE CAR DROVE AND SHIFTED NORMALLY. I ARRIVED AT MY DESTINATION, TURNED THE CAR OFF FOR 5-7 HOURS, STARED IT, AND ITEMS 6 AND 7 ABOVE NO LONGER APPEARED ON THE DASHBOARD. THIS WAS THE 3RD TIME THE CAR HAD 'MIS-SHIFTED' UNDER THOSE SAME DRIVING CONDITIONS (60-68 MPH FOR APPROXIMATELY 20MINUTES, BUT THE FIRST TIME I'D GOTTEN AND FLASHING TRANSMISSION INDICATOR AND THE REST AS STATED IN ITEMS #1-8 ABOVE. I AM VERY CONCERNED ABOUT THESE TRANSMISSION/SOFTWARE PROBLEMS. WHEN IT OCCURS IT TRULY DOES CREATE A SAFETY ISSUE AS THE CAR NO LONGER ACCELERATES AND ONLY FORWARD MOMENTUM IS MOVING THE CAR FORWARD.

WHEN DRIVING DOWN THE HIGHWAY THE CAR PICKS UP A GUARDRAIL AND THINKS IT IS AN OBJECT. THE AUTOMATIC BRAKING SYSTEM TURNS ON AND THERE IS A GRINDING BRAKE THAT GETS APPLIED WHILE YOU ARE DOING 65 MPH ON THE HIGHWAY. IT'S REALLY UNSAFE.

There are two parts to this complaint. The issue regarding the transmission is potentially a safety issue and could result in an accident, while the peeling paint problem is already addressed in the Acura Service Bulletin 19-029 for VINs other than mine. Both are well documented problems that have been experienced by other 2016 Acura MDX owners. The transmission issue is an intermittent problem while accelerating and decelerating. There is a abrupt hesitation, or surging. While coating down a steep hil, the transmission will stay in gear at very high revs instead of shifting. These are an annoyance, but the acceleration problem could cause someone to hit the car from behind in heavy traffic situations. Some individuals note on the internet that their engines would accually stall when accelerating. I have brought my vehicle into the Acura Dealership on a number of occasions without the problem being resolved. The paint issue involves the white diamond pearl paint coming off the roof and is already addressed in Acura Service Bulleting 19-029. It is unthinkable that only some VINs are covered while others are not, if the same exact problem seems to exist on non-listed VINs. Honda Motor Company indicated that they would not add additional VINS unless directed to by NHTSA. Please have Honda extend the warranty on ALL 2016 Acura MDX models with the same problem.

WHILE DRIVING ALL WARNING AND HAZARD LIGHTS COM ON HAS HAPPENED 3 TIMES NOW IN DEALER SHOP FOR OVER A MONTH I DO NOT FELL SAFE IN CAR THE DEALER CAN NOT TELL ME WEATHER SAFE OR NOT AND DOES NOT SEEM TO BE ABLE TO FIX PROBLEM

SPARE TIRE ,AS MOUNTED IN REAR UNDER VEHICLE, IS SHOWING EXCESSIVE WEAR ON SIDE WALL THE WEAR MARKS AS RUBBING THROUGH THE SIDEWALL WHICH IS THE WEAKEST PART ON THE TIRE AND I AM AFRAID TO USE IT. THE TIRE HAS NEVER BEEN USED. I HAVE CHECKED THE PRESSURE 3 TIMES SINCE I PURCHASED THE VEHICLE NEW AND THERE ARE THREE WEAR MARKS FROM THE STORAGE AREA WHERE THE TIRE IS KEPT. ALSO WHEN I PURCHASED THE VEHICLE THE SALESMAN MADE A BIG DEAL ABOUT THE REARVIEW MIRRORS AUTOMATICALLY AIMING DOWN AS THE CAR IS PUT IN REVERSE. THIS SAFETY FEATURE ALLOWS THE DRIVER TO SEE WHAT IS ON THE GROUND NEAR THE REAR TIRES WHEN BACKING UP.AFTER APPROXIMATELY ONE YEAR THE REARVIEW MIRRORS NO LONGER AIMED DOWN. THE DEALER NOW SAYS THAT IS VEHICLE NEVER DID THIS AND I HAVE ASKED ABOUT IT AT 3 DIFFERENT SERVICE APPOINTMENTS. ALSO ABOUT THE SPARE TIRE WEAR , THE DEALER SAID "DON'T WORRY ABOUT IT", AFTER I COMPLAINED ABOUT IT. ORDI CASEMENT # 11194881 NO ACCIDENT OR INJURY HAS OCCURRED BUT THE COMPLAINT IS PROACTIVE PREVENTION SINCE THE POTENTIAL FOR AN ACCIDENT OR INJURY IS POSSIBLE.. ALSO THE REARVIEW MIRROR PROBLEM HAS BEEN AROUND SINCE 2010 BASED ON READING ACURA BLOGS POSTED BY OWNERS.

I WAS DRIVING STRAIGHT ON A RESIDENTIAL STREET AT AROUND 20-25 MPH WHEN ALL OF A SUDDEN I HEAR A LOUD SNAPPING SOUND. I IMMEDIATELY LOST ALL CONTROL OF THE VEHICLE AND IT JERKED HARD TO THE RIGHT HITTING TWO PARKED VEHICLES. UPON INSPECTION, IT APPEARS AS THOUGH THE REAR CONTROL ARM ON THE PASSENGER SIDE FRONT WHEEL SNAPPED, CAUSING ME TO LOSE CONTROL.

THE TRANSMISSION ON THIS VEHICLE IS UNSAFE & THE CAR SURGES UNCONTROLLABLY DRIVING DOWNHILL. MY WIFE & I CAN NO LONGER DRIVE THIS CAR & OUR LOCAL OAKLAND, CA ACURA DEALER HAS NOT CORRECTED THE PROBLEM - WE HAVE TAKEN IT IN FOR CORRECTION SEVERAL TIMES. WE HAVE 3 KIDS SO WE CAN'T DRIVE AROUND IN AN UNSAFE CAR & DONT WANT SOMEONE ELSE DRIVING AN UNSAFE CAR. ACURA RECENTLY ISSUED A WARRANTY EXTENSION ON THIS ISSUE - THIS CAR IS LEASED & WE WANT TO TURN IT IN NOW. PLEASE ASSIST. [XXX] - [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).'*JB

This vehicle is affected by Acura’s 9-speed transmission warmer defect covered under: • TSB B17-009 – Product Update: Transmission Warmer • TSB B17-010 – Product Update / Warmer Replacement • TSB B17-026 – Warranty Extension: 10 years from in-service date, unlimited mileage These bulletins address failures of the transmission warmer that allow coolant and ATF to mix, causing internal transmission damage. My MDX was used by Acura in early 2016–2017 as an engineering/diagnostic vehicle when this defect was being investigated. Repair history: • March 2017 – Transmission replaced, but the updated warmer (released later in 2017) was not installed. • December 2017 – Acura performed a coolant/ATF line flush due to contamination, confirming fluid mixing from the warmer failure. Current issue: My transmission is again showing symptoms consistent with damage caused by the same warmer defect. Despite the active 10-year/unlimited-mileage warranty extension, the dealership refuses to perform the required warranty inspection unless I first pay a $138 diagnostic fee. Under the Magnuson–Moss Warranty Act, a dealer may not charge for diagnosing a defect that may be covered under a warranty or recall. Acura Corporate says the dealer “is allowed to refuse,” and the dealer says they need Acura authorization. As a result, no inspection has been performed. The vehicle has been sitting at the dealership since October 1 with no diagnostic work completed. Concerns: • Failure to perform a safety-related warranty inspection • Failure to complete the product-update remedy • Charging for a warranty-covered diagnosis • Leaving a known defect unaddressed I request NHTSA review this matter, as it involves an active safety-related defect with a warranty extension where both the manufacturer and dealer refuse to complete the required inspection and repairs.

I WAS MAILED A LETTER ABOUT A WARRANTY EXTENSION FOR MY ASSOCIATED VIN. I DEFINITELY HAVE EXPERIENCED ASSOCIATED ISSUES WITH MY MDX. AFTER CALLING THE ACURA DEALERSHIP ON 11/24/17, I WAS GIVEN AN APPOINTMENT FOR 11/28/17 AND I WAS TOLD THEY WOULD INSPECT MY CAR OVER 2 DAYS AND PROVIDE A LOANER CAR. MY EXPERIENCE WAS "TO SAY THE LEAST" THE INVERSE; EXTREMELY DISAPPOINTING. THE SERVICE TECHNICIAN TOOK MY CAR FOR A TEST DRIVE AND TOLD ME NOTHING WAS WRONG. IN ADDITION, THE SERVICE TEAM WAS EXTREMELY UNPROFESSIONAL AS ONCE AGAIN, THE CUSTOMER WAS WRONG. PLEASE ADVISE ABOUT THE NEXT STEPS FOR SERVICE. I AM EXTREMELY DISAPPOINTED WITH ACURA UNWILLINGNESS TO LISTEN TO THE CUSTOMER. I DID TAKE THE CAR FOR SERVICE ASSOCIATED WITH THIS ISSUE ABOUT A MONTH PRIOR. OVERALL PROBLEM IS MANY TIMES I EXPERIENCE SHIFTING AND ACCELERATING HESITATION THAT IS JERKY. WHICH INDICATES A PROBLEM WITH THE TRANSMISSION: THIS IS WHAT THE WARRANTY EXTENSION STATES .... THE TRANSMISSION SHIFTS POORLY.

ALL DASH DISPLAY WARNING LIGHTS WILL COME ON SPORADICALLY WHILE STANDING OR IN MOTION, LAST FROM A FEW HOURS TO A FEW DAYS OR SO, WHICH CAUSES VEHICLE SPEED TO DECREASE AND CERTAIN FEATURES TO NOT WORK. DEALER SERVICE UNABLE TO RESOLVE PROBLEM, BUT WILL CLEAR ERROR CODES IN COMPUTER TO SHUT OFF WARNING LIGHTS.

VEHICLE MAKING HIGH-PITCH CHIRP AFTER ENGINE IS WARM. NOTICABLE AT IDLE. NOT NOTICABLE DURING DRIVING/CRUISING SPEEDS. TOOK VEHICLE TO DEALER REGARDING HIGH-PRESSURE FUEL PUMP TSB. DEALER STATED THAT HIGH-PRESSURE FUEL PUMP WAS NOT INVOLVED. STATED IT MAY BE DUE TO THE STARTER (DEFECTIVE SOLENOID OR DRIVE PISTON NOT DISENGAGING). NO CURRENT TSB EXISTS FOR STARTERS. PLEASE INVESTIGATE.

AT 80,000 MILES CAR STARTED MAKING A NOISE SOUNDING LIKE METAL SPINNING ON METAL. TRANSMISSION SYSTEM PROBLEM LIGHT CAME ON. RPMS WENT REALLY HIGH WHEN I TOOK MY FOOT OFF THE GAS THE RPMS WENT REALLY LOW. THIS ALL HAPPENED WHILE I WAS ON THE HIGHWAY. PULLED OVER, SHUT CAR OFF, RESTARTED CAR, WARNING LIGHT WENT AWAY RPMS WERE FINE BUT THE NOISE WAS STILL THERE. TOOK CAR IN FOR SERVICE THEY COULDN'T FIND ANY PROBLEM HAD TRANSMISSION FLUID REPLACED AND THE NOISE WENT AWAY HOWEVER OCCASIONALLY THE TRANSMISSION SYSTEM PROBLEM WOULD OCCUR. SO I SHUT OFF THE CAR RESTART AND THE PROBLEM GOES AWAY. SEEMS THE TRANSMISSION PROBLEM HAPPENS WHEN I'M ON THE HIGHWAY AND GOING UP HILL BETWEEN 60 AND 70 MILES AN HOUR WHEN THE RPMS GO SLIGHTLY ABOVE TWO. IT DOES NOT SEEM TO HAPPEN ON LEVEL GROUND. I DO MOSTLY CITY DRIVING AND PUT ANOTHER 50,000 MILES ON SINCE THE FIRST TIME THE PROBLEM HAPPENED. TOOK CAR IN FOR SERVICE WHILE THE LIGHT WAS ON, DIAGNOSTIC SHOWS TORQUE CONVERTER PROBLEM. THEY TELL ME I NEED A NEW TRANSMISSION. APPARENTLY 2016 MODELS YOU CANNOT REBUILD BECAUSE THERE ARE NO PARTS AVAILABLE. STILL DRIVING CAR TODAY WITH NO PROBLEM DOING CITY DRIVING BUT I ALWAYS PANIC WHEN I HAVE TO GET ON THE HIGHWAY. APPARENTLY I'VE GONE 60,000 MILES MORE WITH A TRANSMISSION THAT CANNOT GO ON A HIGHWAY UPHILL. JUST RECENTLY MY CAR IS BEEN GOING INTO NEUTRAL BY ITSELF AND IT STALLS OCCASIONALLY. THIS HAPPENS WHILE I'M DRIVING. I FEEL VERY UNSAFE BUT I DON'T HAVE THE MONEY TO REPLACE MY TRANSMISSION. I WISH THE TORQUE CONVERTER COULD BE REPLACED BUT THERE ARE NO PARTS AVAILABLE. I BELIEVE ACURA IS NOT ADMITTING TO A PROBLEM

THE 9 SPEED TRANSMISSION ON THIS CAR IS TERRIBLE. HARD SHIFTING, LUNGING FORWARD, THE CAR ACCELERATES ON IT'S OWN LIKE IT DOESN'T KNOW WHICH GEAR IT SHOULD BE IN. WHEN ACCELERATING, THE CAR HESITATES AND FEELS LIKE IT LOSES POWER. THIS IS A VERY DANGEROUS VEHICLE. TOOK IT TO THE DEALER SEVERAL TIMES AND THEY SAY THIS IS THE WAY THE CAR WAS DESIGNED. IT WAS DONE TO MEET FUEL EFFICIENCY STANDARDS. ACURA IS SACRIFICING SAFETY AND COMFORT IN ORDER TO MEET THE FUEL STANDARDS.

AS THE VEHICLE IS MOVING AT 60 -70 MPH AND YOU DECELERATE OR REDUCE ACCELERATION THE RPM GOES TO ZERO, CAR CANNOT ACCELERATE AND YOU DO NOT CONTROL OVER ACCELERATION IN MOVING TRAFFIC. IF THE CAR IIS COASTING AND NOT ABLE TO HAVE A STABLE SPEED WITH MOVING TRAFFIC THIS IS CAN BE DANGEROUS. SUDDENLY, THE TRANSMISSION WILL ENGAGE WITH A SHARP ENGAGEMENT (METAL SOUND) OF THE TRANSMISSION AFTER ABOUT 6-10 SECONDS. I COMPLAINED TO THE DEALER AS THIS HAS HAPPENED SEVERAL TIMES. THEY SAID THEY COULD NOT HELP ME SINCE THERE WAS NOTHING WRONG AT THE TIME OF INSPECTION AND THEY HAVE NOT HEARD ABOUT THIS PROBLEM. LAST WEEK SIMILAR SITUATION OCCURRED EXCEPT THE DASHBOARD ERROR LIGHTS SHOWED SH-AWD, EMISSIONS, TRANSMISSION PROBLEMS AND REAR SIDE WARNING INDICATOR FAULT. I HAD TO PULL OF ONTO THE SIDE OF ROAD. ONCE IN PARK THE CAR WOULD ONLY GO INTO SPORT MODE IN FIRST GEAR. CALLED ACURA ROADSIDE ASSISTANCE AND THEY TOWED TO A LOCAL DEALER. NEXT MORNING THEY SAID IT WAS OK. ONCE THEY TESTED VIA DIAGNOSTICS THEY SAID THERE WERE ERRORS IN THE TRANSMISSION MODULATOR. HOPE THIS FIXES THE PROBLEM. CAR HAS 36K MILES ON THE ODOMETER. THE DEALER WAS VERY HELPFUL AND HELPED ME GET TEMPORARY TRANSPORTATION TO MY HOME CITY 4 HOURS AWAY. OTHER PEOPLE ON THE INTERNET ARE HAVING SIMILAR PROBLEMS THAT HAVE OCCURED TO ME. MY BIGGEST CONCERN IS ONCE THE CAR IS OUT OF WARRANTEE THIS BECOMES MY PROBLEM NOT THE MANUFACTURER. WHAT RECOURSE DO I HAVE IF THIS A DESIGN OR QUALITY DEFECT FOR ME AND OTHER CONSUMERS. CURRENT REPAIRS HAVE BEING COMPLETED AND UNKNOWN IF THIS PROBLEM WILL OCCUR AT FUTURE DATE.

I GOT IN MY CAR THIS MORNING AN AS SOON AS I PUT IT IN REVERSE, IT LURCHED FORWARD BEFORE FINALLY MOVING BACKWARDS (THERE WAS NO SLOPE). THEN, AS I APPROACHED A TRAFFIC LIGHT ON A CITY STREET AND APPLIED THE BRAKE, THE CAR FELT AS THOUGH IT ACCELERATED SLIGHTLY BEFORE SLOWING DOWN.

TL* THE CONTACT OWNS A 2016 ACURA MDX. WHILE DRIVING APPROXIMATELY 5 MPH AND ATTEMPTING TO DEPRESS THE BRAKE PEDAL, THE VEHICLE INADVERTENTLY ACCELERATED WITHOUT WARNING. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES. THE CONTACT ALSO STATED THAT WHEN THE GEAR WAS SHIFTED BETWEEN THE FOURTH AND FIFTH GEARS, WHILE DRIVING APPROXIMATELY 35 MPH, THE VEHICLE DID NOT ACCELERATE FOR ABOUT TWO SECONDS. THE VEHICLE WAS TAKEN TO ACURA OF MODESTO (4325 MCHENRY AVE, MODESTO, CA 95356, (209) 527-7000) WHERE IT WAS DIAGNOSED THAT THE VEHICLE WAS PERFORMING AS DESIGNED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND REFERRED THE CONTACT TO THE DEALER. THE FAILURE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 300.

VEHICLE JERKED WHILE STOPPING (IN MOTION), VEHICLE WOULD HESITATE ON ACCELERATION (IN MOTION OR FROM A STOP), THIS WAS FOLLOWED BY FLASHING ERROR LIGHTS. THE VEHICLE WAS INOPERABLE AND HAD TO BE TOWED IN BY ACURA SERVICE.

WE BOUGHT A NEW MDX 2016 AND THE CAR WAS ACTING VERY STRANGE.THE POWERTRAIN WAS OFF, 30000 MILES ENGINE WAS OUT IN THE MIDDLE OF THE ROAD, NOISES EVERYWHERE. IT IS IN THE SHOP NOW AND IT HAS BEEN 2 MONTHS NOW SINCE REPAIR.IT IS STILL IN THE SHOP AND IT HAS BEEN OVER 2 MONTHS.

THIS ISSUE INVOLVES THE FWS(FORWARD WARNING SYSTEM) ON THIS VEHICLE THE FWS OPERATES INTERMITTENTLY AND ERRACTICALLY. WHEN DRIVING HOME IN THE RAIN TODAY IT FLASHED ON AND OFF WITHOUT ANOTHER VEHICLE NEARBY. IN MANY CASES IT HAS FAILED TO WARN WHEN I AM APPROACHING ANOTHER VEHICLE AT CONSIDERATE SPEED. IN MOST CASES IT HAS FAILED TO WARN. THIS INTERMITTENT AND APPARENT OPERATION HAS SERVED AS A DISTRACTION AND HAS BECOME A SAFETY ISSUE, THE SALESMAN AND SERVICE MANAGER HAVE INTIMATED THAT THIS CAN BE CONSIDERED "NORMAL" FOR THIS SYSTEM. FOR ME THIS PROBLEM RESULTED IN A NEAR COLLISION AND AM CONCERNED FOR OTHER DRIVERS EXPERIENCING THE SAME PROBLEM THIS PROBLEM OCCURRED IN CITY AND HIGHWAY DRIVING (ROAD TRIP FROM WEST COAST TO CHICAGO AND BACK) ONLY OCCURS WHEN IN MOTION WHETHER TURNING OR NOT.

DEAR SIR/MADAM - I WAS HEADING TO MY OFFICE FROM HOME ON THE HIGHWAY CA-84. WHILE DRIVING TODAY ON THE HIGHWAY AT AROUND 50MPH I HEAR SUDDEN LOUD POP UP SOUND FROM THE ROOF, I FELT LIKE AN EARTHQUAKE AND VEHICLE STARTING TO SHAKE. AS I SLOWED DOWN I FELT SOMETHING WRONG WITH SUNROOF. SINCE HIGHWAY LEADS TO THE BRIDGE AND HAS NO EXIT I CONTINUED TO DRIVE. HIGHWAY BECOMES INTERNAL ROAD AFTER 5 MILES. AS I GOT AN OPPORTUNITY I PARKED THE VEHICLE AND GET ABOVE TO CHECK WHAT REALLY HAPPENED. I WAS AMAZED TO SEE SUNROOF GLASS IS BROKEN, BUT MOST IMPORTANTLY THE ENTIRE CASING IS CAVING IN. THIS IS VERY SERIOUS SAFETY ISSUE. SINCE THIS VEHICLE IS PRIME FOR MY KIDS COMMUTE I'M NOT SURE HOW SAFE THIS VEHICLE IS.

WHILE APPRACHIING A RED LIGHT. I APPLIED THE BRAKES AND VEHICLE APPEARED TO ACCELERATE AND BRAKES DID NOT STOP CAR, I TURNED RIGHT ON TO SHOULDER OF MAJPR HIGHWAY TO AVOID ACCIDENT. NEXT DAY .WHILE BRAKING TO PARK, CAR WOUND NOT STOP AND ROLLED INTO FIELD. MY WIFE WAS WITH ME TO CONFIRM IT WAS NOT ME PUSHING THE GAS PETAL BY MISTAKE.

TRANSMITION PROBLEM ( ELECTRICAL )

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

TRAVELING ABOUT 30 MPH IN A STRAIGHT LINE IN TRAFFIC. MDX SUDDENLY WOULDN'T ACCELERATE. CAR STARTED SLOWING EVEN THOUGH ENGINE WAS STILL RUNNING. I WAS ABLE TO PULL OFF TO CURB. COULDN'T SHIFT. CUT ENGINE OFF AND RESTARTED. CAR THEN RAN NORMAL.

SUNROOF EXPLODED ALL OF A SUDDEN WHILE DRIVING ON A FREEWAY AT AROUND 70MPH. HEARD AN EXPLOSION ABOVE THE CAR, HAD TO PULL OVER IMMEDIATELY, AND FOUND THAT THE SUNROOF HAD EXPLODED. I HAVE A ROOF TOP BOX BUT THERE IS NO WAY THIS CAN MAKE CONTACT WITH THE SUNROOF. AS YOU CAN SEE IN THE PICTURE, THE EXPLOSION WAS OUTWARDS. GOOD THING OUR INSIDE SLIDING ROOF WAS CLOSED! WE ALSO HAD 2 KIDS IN THE CAR AT THE TIME.

INEXPLAINABLE BATTERY DRAIN ON SEVERAL OCCASIONS RESULTING IN NOT ENOUGH POWER TO START CAR. NO SOLUTION FROM ACURA EXCEPT THAT IT HAPPENS TO A LOT OF OWNERS. MOST RECENTLY CAR DIED IN AN INTERSECTION (WITH TWO KIDS IN CAR) AND COULD NOT RESTART OR SHIFT TO NEUTRAL (WITHOUT POWER) TO MOVE OUT OF INTERSECTION. CAR WAS STOPPED AT INTERSECTION, DRIVER MOVED FORWARD TO MAKE TURN, DRIVER STOPPED IN INTERSECTION AND AUTO-IDLE ENGAGED (TURNING CAR OFF MOMENTARILY), WHEN DRIVER RELEASED BRAKE, WHICH WOULD NORMALLY RESTART ENGINE, CAR WOULD NOT RESTART DUE TO LOSS OF POWER. STUCK FOR AN HOUR IN MIDDLE OF INTERSECTION UNTIL JUMPED. THREE DAYS PRIOR TO THAT, CAR SAT FOR 5 DAYS WITHOUT USE IN 40-50 DEGREE WEATHER, AND BATTERY WAS DEAD WHEN ATTEMPTED TO START. SEEMS TO BE A PARASITIC DRAIN OR FAULTY CHARGING ELECTRICAL PROBLEM WITH CAR.
