Other Fuel System Problems of Acura MDX - part 2

In February 2024, received a recall for fuel pump module, which can result in prevent engine from starting, cause vehicle to lose driver power, or stall while driving. Can also result in failing emissions inspection. Acura reports that repair is not available until fall 2024. In October 2024, while at a stoplight, auto idle-stop was engaged, and engine stalled and would not turn on. Vehicle needed to be turned off and then engine started at that time. A previous recall that affected auto idle stop was addressed in may 2023 where engine does not auto restart after entering auto idle stop. In April 2023 Acura provided a software update, however in October 2024 the engine stalled as mentioned above. Additionally, a local emissions test was performed and failed around April 2022, and passed a second time when performed a few weeks later. Even after experiencing symptoms of recall 23v-858, recall has not been able to be addressed. This vehicle was brought into Acura in November 2024 for an another recall (23v-751) and I was told that current unaddressed recall may be available within the following month but could not provide any further assistance. Engine stalling at a stoplight puts my family at risk, as well as others. If engine is stalling at a stoplight, engine may stall at other times, including while driving, increasing risk of accident. Recall has been undressed for almost 10 months.

From a stop, the vehicle will lurch forward after 1 second of acceleration without a change in the amount of pressure on the gas pedal, as if there is a delayed input to the throttle position. This only happens from a complete stop, such as at red lights, stop signs, or in heavy stop and go traffic. On multiple occasions I have almost rear ended the vehicle in front of me as a result of this. There are no warning lamps or error messages displayed in the gauge cluster. I have not been able to have this inspected by any of the Acura dealers in a 25 mile radius, because when I called to make an appointment for the connecting rod bearing recall, the earliest opening was March of 2026.

Auto idle mode - after we've stopped and released the brake to go forward, the car will then shift to neutral by itself instead of restarting to drive. This has happened frequently and is now starting to happen more often. This is a safety issue, especially if you're the last car in line and other cars are traveling 55-60 miles behind you on a major road and see a green light ahead. Each time this happens, we have to turn off the car and try to restart the car, and sometimes this has been iffy and we've had to repeat the process a couple of times. There were no warning lights of problems with any of car components. . Read more...

1. ) I have had repeated, on-going issues with the fuel propulsion system since the day I bought the car. When I step on the accelerator it randomly (lately more constant than random) does not respond, then it will shoot me out into traffic. For example when I am entering the highway from an onramp, I see my opportunity to merge into traffic and I step on the gas - nothing - no response, then it suddenly accelerates and shoots me into oncoming traffic. This is so bad that I am afraid to drive the vehicle. It is deadly. I have reported the issue every time I have had the car serviced (always dealer serviced, from same dealer where I bought it. ) 2. ) the vehicle will randomly decide that I am going to hit a car in another lane, and will forcefully apply the brakes (when there is no issue, no danger, no possible way I am going to even be close to hitting another car) causing the cars behind me to come extremely close to rear-ending me! or the car will decide I am going off the road when I am taking a soft curve, and it will sound a warning and try to turn the wheel. 3. ) the display panel will go black for no reason. I then cannot use the navigation screen. It will randomly return after a few hours or after a day or two. 4. ) the camera/display will get stuck on the reverse camera causing a visual disconnect as I drive forward, but can only see what is in reverse. (like seasickness). No idea what causes it or how to fix it. Eventually it corrects itself after a few hours/day+. 5. ) car will occasionally make a strange squealing noise after it has been turned off - no idea what that is, or what causes it. As a salesperson who spends many, many hours in her car, this vehicle has become a constant danger to both my livelihood and my life. I am afraid to drive it and I will not let family members drive it as I am afraid for their lives due to the issues stated above.

The fuel pump impeller was improperly moulded, resulting in low density impellers. Over time, the low-density impeller can deform and interfere with the fuel pump body, rendering the fuel pump inoperative. If the fuel pump module is inoperative, the engine may not start or can stall while driving, increasing the risk of a crash or injury. Difficulty starting, engine hesitation while driving, or an illuminated check engine light.

The car periodically loses power while driving. In traffic this has caused some very scary and hazardous incidents while vehicles zoom around us or as we attempt to make it to the shoulder of the road. We do not get warning lights when it happens. The dealer (cincinnati columbia accura) has confirmed the fuel pump safety recall but has done nothing to fix it.

I was driving down the highway today at 70 mph and all the lights illuminated on my Mdx. It began to struggle to keep speed and eventually shut down once I was on the service road. I was extremely scared and nervous that I was going to be involved in an accident or the car was going to blow up as it started bouncing up and down while I was still on the highway.

We have a 2016 Acura Mdx and it has automatically shifted to neutral 3 times (twice while driving on the freeway and 1x yesterday while driving on the street at normal speeds) in the last 2 months. On the Mdx dashboard, it will display "emissions system problem" and then display "stop driving when safe. Transmission problem. See manual. " however, the car will automatically shift to neutral within seconds. My children's lives (7 y/o and 5 y/o) were placed in danger as a result of this system failure. I have contacted the Acura Honda recall specialists and client relations representatives. The car is being diagnosed at cerritos Acura dealership at the present time. A case number has been filed since our VIN shows no recall, despite it having recalls for other 2016 Acura Mdxs.

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.

Upon turning right, the car lost power, degraded acceleration as if someone is holding and pulling the car to move forward. The traffic behind me expected me to cathup with the speed on the road but due to loss of power and engine hesitation I got honked and was luck to avoid a crash from behind on a busy road. Acura dealership in dallas dont have parts since a very long time. They have pleant of new cars to sell but not repair.

Two recalls outstanding from November 2023. Parts not available to fix the problems until April 2025.

I received a letter from Acura in January 2024 regarding the engine crankshaft recall. I have called the two closest Acura dealerships in an attempt to get this fixed. The last that I was informed today by a dealership is "the part is expected to arrive in August, and we are booked out until December". This put me at getting this repair fixed at one year after Acura sent me this letter admitting the crankshaft issue. My vehicle has stalled sporadically while driving for the entire two years that I have owned it. The letter from Acura states that this recall can cause the "rod bearing to prematurely wear and seize, causing engine damage which may cause the engine to run improperly or stall while driving, increasing the risk of fire, crash, or injury. I would like Acura to fix my car or put me and my family in a safe alternative.

Acura mailed me details about NHTSA recall 23v-858 in February 2024. However, the letter stated that parts won't be available until over half a year later in the fall of 2024. While I understand that it takes time to develop and produce parts, a half a year wait seems like an unusually long time to have to wait while my vehicle is considered unsafe by NHTSA. This makes it seem like Acura is prioritizing producing parts for profit over safety.

See attachment for detailed explanation.

Mil is displaying the following dtcs: p0441 p04f1 Acura dealership is stating TSB - 21-081 does not apply to my year, make, model vehicle. Is the information I am receiving accurate?.

I have a recall on my 2019 Acura Mdx for a faulty fuel pump. I have called 2 different dealers in my area, the first said they wouldn't have the parts to fix the car until December 2024 at the earliest, the second just stated that they don't have the parts. It seems to me this is quite a bit of time to be driving with a suspected faulty fuel pump. It is April 30,2024.

I have three recalls on my vehicle. I am trying to get them serviced and the Acura dealership is stating that they do not know when they can service the fuel pump because they haven't created/issued any parts. They will not let me book to service/fix the connector rod bearing before August. I am concerned with the safety of my vehicle due to these recalls and not being able to get them fixed ASAP.

Acura Mdx 2016 sh-awd with 113366 miles diagnosis according to warning lights. Dtc test certification codes: p0301 misfire no. 1 cylinder p0306 misfire no. 6 cylinder p0300 random misfire p0420 catalyst system efficiency below threshold b1 recommendation was that the catalytic converter be replaced. All these codes were identified under Honda's TSB 20-100 dated 2/2021 on odyssey, pilot and ridgeline models where ah extended warranty to 10 years from date of purchase or 150k. These v6 engines are pretty close to that of the 2016 Mdx. Is there a remote possibility that these dtc codes could exist in Mdx v6 engines when an issue arises similar to those in the Honda vehicles? these dtc codes appeared 24 hours/37 miles after a routine oil service on 3/26/2024 at advantage Acura of naperville with a perfect inspection report. The malfunction occurred in the vicinity of mcgrath Acura of westmont on the following day of 3/27/2024. The concern is if any of the emission system components were damaged during the routine oil service. Advantage Acura have in the past installed brake pads backwards on my Acura tl 2010 for which I do have proof.

Nhtsa recall number 23v-858. Honda/Acura still have not fix my car supposedly due to they are short on the fuel pump part.

The dealership is refusing to fix the issue citing that the parts will not be available until fall of 2024. My vehicle is unsafe to drive.

While driving the vehicle at highway speeds the accelerator pedal became unresponsive. Additional force on the pedal pushed it to the floor with no response from the engine. After letting off the pedal while trying to pull the vehicle over to a safe location along the road, a press on the pedal from fully released, caused the engine to rev up and propel the vehicle again. This has happened 3 times but is very random, and not easily reproducible. It is a very unsafe condition when it does happen as the vehicle loses speed, and the driver no longer has speed control!.

On February 7 at 2:30 I came home, and my car was unable to turn off. I’ll try several times to turn off the car by pressing the on and off button. While driving back to work, the car change gear from being in drive, and it went into neutral while I was driving. I was able to pull over and I was able to turn off the car by pressing the button. The entire dashboard lights came on with all the different symbols . I was able to exit the carr. I told my car to a local repair shop. This was a very frightening experience, especially when I was driving, and the car went into neutral it could’ve been worse.

Received recall notice Feb 2024 tried 3 times to get fixed no fuel pump available yet this is a safety recall issue and should be fixed immediately please help expediate this urgent issue.

Received a recall notice Feb 2024. It is now 9 months later and manufacturer has said they have no eta when parts will be available after multiple calls. They are vague with the issues. Told if I think I have the issue, I can bring my car in for diagnosis. If they don't find the problem I have to continue to wait and they will charge a diagnostics fee for troubleshooting. I am concerned I have an unreliable vehicle that could fail at any time. I think 9 months is more than reasonable to have a recall fixed and replacement parts manufactured.

While driving on the highway, at highway speeds, all dash lights came on and the vehicle immediately lost power coming to an abrupt stop. We were able to limp the car to the side of the road. It was ultimately determined that the car’s fuel pump had gone out. The fuel pump was replaced by Acura, and covered under the initial manufactures warranty. However, it’s rather suspicious that our car is not included in the recall given that the fuel pump failure is identical to the open recall for our same make and model.

What component or system failed or malfunctioned, and is it available for inspection upon request? - immobiliser system. Yes, available. May be repaired by local mechanic unless I learn from you to defer such repair. How was your safety or the safety of others put at risk? - the inappropriate activation of the immobilizer system (at least I think that's what happened) caused the vehicle immediately to become unnamageable. All lights off, motor stopped, no power brakes pr power steering. No way to give warning to other drivers. Has the problem been reproduced or confirmed by a dealer or independent service center? - the identical behavior has occurred about 6 times, once on busy us 101 through downtown oakland, CA during rush hour. The car will be towed to a mechanic's shop later today. I have no history with this mechanic's shop. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - no. It is my inference that the immobilizer system activated while at speed due to description in the owner's manual of the appropriate behavior of the immobilizer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - no. The first appearance of the "green key" light preceded the entire shutdown by only a few seconds.

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.

We have two stop sale safety recalls on our 2018 Acura Mdx that have gone over a year without being addressed. I have contacted Acura and the dealership multiple times. Acura refers me to the dealer and the dealer refers me to Acura. Apparently there is no accountability for important safety recalls. Would appreciate some help from NHTSA.

I put premium gas all the time but the vehicle seems to consume excess amount of fuel. Not sure if the computer is has issues with the readings or fuel pump has an issues.

My wife went to the grocery store and turned the car off. And upon doing so the car started smoking and she opened the hood and it was on fire. She opened the hood and put out the fire.
