2017 Acura MDX Fuel system Problems

When accelerating into traffic (usually merging onto highway or changing lanes on the highway) my car will loose all power and fail to accelerate. This is extremely dangerous and has happened on several occasions. I have taken this into Acura as well as other automotive dealers and no one can seem to diagnose or recreate the problem. The only support I received from Acura has been a “software update & idle relearn”, which has never fixed the problem. I saw an NHTSA ID#23V85800 recall alert for Fuel Pump Failure, which perfectly describes the issues I’m having. Unfortunately, my VIN is not included in this recall. I respectfully request that you add my VIN to this recall so I can get my fuel pump replaced and hopefully resolve this very dangerous issue.

When I have already started to go in motion, for example when turning left, and I let go of the gas pedal and then press the gas again once I decide its safe to turn, my car doesn't respond to the gas for about a couple of seconds. This has also happened when I am driving on the highway and I am already in motion and I want to go faster to pass another vehicle, my car hesitates for a couple of seconds before it responds to me pushing the gas pedal.

I noticed a whirring sound while driving my MDX. The repair shop investigated and noted that the bearing in my transfer case assembly is failing and needs immediate replacement to prevent total power loss to the propulsion system of the car. Current milage of the vehicle is 99,500.

Hello, I am writing to report that my 2017 vehicle is experiencing the same issue that was subject to a recall on the 2016 models. Despite the recall being associated with the 2016 year, my 2017 vehicle is showing identical symptoms and concerns. This raises serious questions about safety, reliability, and whether this issue extends beyond the originally recalled model year. I would like this concern formally documented and request a review of my vehicle to determine whether it qualifies for repair, inspection, or coverage related to the prior recall. Please advise on the next steps and whether this issue has been reported or addressed for 2017 models. Vehicle details: Year: 2017 I appreciate your prompt attention to this matter and look forward to your response. Sincerely, [XXX] If I get killed me or my [XXX] son, you all will be responsible. You made these faulty vehicles. [XXX] I'm have to get a lawyer involved if issues are not addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2017 Acura MDX died on me 3 times in the middle of the street last year 2024, July. All the warning lights got turned on the dashboard all 3 times. Car staled and could not turn it on right away. I managed to turn it on and after few seconds turned its self off. It felt like fuel injectors were not working properly or fuel pump. I tried few more other times and got turned on and drove it home. Next day all the warning light went away. Day after, i drove it to grocery store and on stop light same thing happened. I decided to take it to Acura dealership, on the way there all the warning lights turned off by it self. They could not find that anything is wrong with it.

From a standstill, Car often does not accelerate right away when accelerator depressed (even floored). Often times there is a significant lag between depressing the accelerator and actual propulsion, as if fuel not being injected (then car peels out from sudden injection). Last year I did Internet research to find that my model year is part of a range of acuras that share this problem. Today I received a recall notification for this very problem on an app. When I entered my VIN on the NHTSA website it said my car VIN was not part of the recall, but it is the exact problem described in the recall and my car is part of the described range of models in the specified date range.

While driving the car started to loose momentum and began stuttering until finally stopping abruptly and applying the electronic braking system. All warning alarms were illuminated on the dash. I was not even able to pull over completely off the road either putting me and my family in danger from not being off the road. Acura dealership service center informed me it was a bad high pressure fuel pump located on the engine block itself. There are recalls for this exact part neginnibg from 2018 on the acura MDX model. My model is a 2017 making me wonder if the recall should include earlier year models of acura mdx.

at highway speeds, the transmission unexpectedly shifts to neutral with no warning. The only indication is unexpected decrease in speed and accompanying engine rev. My typical driver response is to take foot off accelerator, then put back on again. Engine overrevs then shifts in to gear. I'd estimate it's out of gear for ~ 5 seconds, but hard to say in the heat of the driving moment. This happens 1-2X most highway trips, but not occur at lower speeds (it does not shift very smoothly in lower gears at times, but it's not currently a safety issue). I've taken it to my local dealer (Hendrick Acura, Durham, NC) and contacted Acura Customer Care, and am trying to get a diagnostic scheduled (it's been a process). The behavior started to worsen over the past several months (e.g. the slip to neutral has lengthened in time) but shorter slips have been occurring for a longer time period.

I was on the feeder road of a major freeway in Houston Texas at a stop the brake fully applied. The auto engine idle stop was enabled. When I removed my foot from the brake the engine did not restart. The lights, radio remained on but I was unable to drive my car or change the gear shift. Being on a freeway feeder was a dangerous place to be stalled and had to wait in major traffic for a tow truck to come as the vehicle could not be started or turned off. Completely inoperable. The check engine light was on and oil light. I was towed to a nearby maintenance shop where a p2638 code was listed. After the car was towed the car would restart. Prior to the incident there have been other occasions where the vehicle struggles to restart the engine from the auto idle. However there were no warning lights. Additionally I scheduled service with the dealership the next day and they show an auto idle recall as an item for repair. There is no recall listed on Nhtsa. Additionally I see a class action lawsuit was filed earlier this week for a potential ongoing, long term issue related to this product.

Fuel pump (High - pressure & low- pressure) failed which has caused significantly reduced acceleration and caused the engine to stall in mid operation of the vehicle. I (Driver) was the only person in the vehicle and there was no crash. I would say there is high risk of a crash and it is a serious safety hazard. There were no warning lamps, messages or other symptoms of the problem prior to the failure.This vehicle component was checked by an independent service center and got it repaired. Fuel pump & high pressure pump was ordered and replaced on the vehicle. I paid $1977.59 as the total cost for parts and labor plus tax.

The car several times now has stopped in traffic and died after the idle stop was initiated while stopped in traffic. It will not start up for at least 30 seconds to a minute. We were almost rear-ended because we were stuck in the middle of the road. I was told that Canada has issued a recall because of this issue

I OWN A 2017 ACURA MDX. THE VIN IS [XXX]. ON SUNDAY JANUARY 13, 2019 MY WIFE WAS PULLING INTO OUR DRIVE WAY WHEN SHE NOTICED SMOKE COMING FROM UNDER THE HOOD. SHE GOT OUR KIDS OUT OF THE CAR JUST BEFORE THE CAR BURST INTO FLAMES. IT?S AMAZING NO ONE WAS HURT. THE CAR, HOWEVER, IS COMPLETELY DESTROYED. THE FIRE DESTROYED OUR OTHER CAR IN THE DRIVEWAY, THE GARAGE DOOR, THE GUTTERS, WINDOWS, THE FRONT DOOR AND A LARGE PART OF THE ROOF. ALL FOUR TIRES EXPLODED AND FLAMING PIECES OF RUBBER WENT ALL OVER OUR HOME AND DRIVE WAY. THE CAR LEFT AN OIL STAIN ACROSS OUR ENTIRE DRIVEWAY. THE CAR WAS STILL UNDER THE ONE YEAR MANUFACTURE END TO END WARRANTY. THE ONLY SERVICE EVER PERFORMED ON THE VEHICLE WAS DONE AT JOHN EAGLE ACURA IN KATY, TEXAS. WE PURCHASED THE SERVICE PACKAGE FROM JOHN EAGLE ACURA WHICH COST ROUGHLY $300.00 AND WAS A COMPLETE WASTE OF MONEY. THE CAR HAD NO WARNINGS AND HAD NO INDICATION OF A SERVICE ENGINE SOON NOTICE. THE CAR WAS REDUCED TO SMOKING RUBBLE. THE CAR IS A PILE OF BROKEN GLASS AND ASHES. THANK YOU. *TR

DANGEROUS LOSS OF POWER WHILE ACCELERATING ON THE HIGHWAY! THERE HAVE BEEN THREE SEPARATE INCIDENCES OVER THE LAST 2 YEARS. WHILE I WAS TRYING TO ACCELERATE ON THE HIGHWAY, THE CAR SEVERELY LOST POWER AND THE "CHECK ENGINE" LIGHT STARTED FLASHING. THE CAR SEEMED TO OPERATE NORMALLY AFTER TURNING OFF AND ON THE ENGINE. THE DEALERSHIP CLAIMED THAT THERE WAS NO COMPUTER RECORDS OF PROBLEMS AFTER EACH INCIDENCE. ACURA JUST ISSUED A RECALL OF THE FUEL PUMP ON THIS MODEL YEAR MDX. HOWEVER, ACURA AND THE LOCAL ACURA DEALERSHIP REFUSED THE REPAIR DUE TO THE LACK OF COMPUTER RECORD OF FAILURE.
