36 Electrical System problem of the 2020 Acura MDX

Failure Date: 10/22/2024

I came to a stop at a stop sign. The start/stop feature activated and the engine shut off. When I lifted my foot off the brake, the engine did not restart (as it's supposed to), and then vehicle automatically shifted itself into neutral (without any of my doing). I put the emergency flashers on to alert other motorists, hoping to avoid a rear-end collision as I was stopped in the middle of an intersection in rush hour traffic. At this time, the battery light illuminated. The engine light illluminated as well. I had to forcefully and unusually push the brakew pedal towards the floor as the vehicle was drifting backwards. At this time, the vehicle would not shift into park. Then "park" illuminated, so I attempted to reapply the brake hoping that when I let up from the brake the car would start again (like the usual procedure). The vehicle then shifted into park, but the engine had not restarted. I pressed the on/off red button to follow normal procedures for turning the vehicle off. With my foot remaining on the brake, I pressed the off/on red button to start the engine as usual and the engine finally restarted. Afraid for the safety for myself and other motorists, I put the vehicle into drive and I pushed the button to stop the stop/start system from engaging. No codes generated during this. This is a safety issue for several reasons. First, I was stuck in the middle of a busy intersection where a large volume of cars travel through each day. It was rush hour, so the roads couldn't be more filled. Someone coming around the corner who might not have been prepared to stop could have hit me. Likewise, I could have been hit while in the intersection. Secondly, once the vehicle failed to turn back on, the washington grove (montgomery county fire and rescue services - mcfrs) was responding to a vehicular file nearby on I-270 and had I not have been able to move in time, some of their vehicles likely wouldn't have made it through because my vehicle was blocking the lane.

38 Electrical System problem of the 2020 Acura MDX

Failure Date: 09/23/2024

When the vehicle is idle, for instance at a light, it will shut down. It idles a little, goes into neutral and shuts completely down having to be restarted. I always turn off the automatic start on the vehicle after I start it, so it is not that. It has also done it while driving. It is very unsafe to be driving in traffic and have your vehicle shut down with no warning. Please advise on what actions should be taken to correct this issue.

39 Electrical System problem of the 2014 Acura MDX

Failure Date: 08/31/2024

We managed to get home with difficulty turning. Car was towed to Acura plesanton and was reported no recalls for this issue.

40 Electrical System problem of the 2020 Acura MDX

Failure Date: 08/29/2024

Twice so far my car just turned itself off while stopped in traffic at a stoplight. It would not turn on immediately. Traffic built behind me, steering was locked, brakes not working. After sitting a minute or so it would start again and then the steering would then work, gas accelerator, brakes would all then start to work again. It was scary and unsafe. This needs a recall!!!.

42 Electrical System problem of the 2015 Acura MDX

Failure Date: 08/26/2024

For the last 50k miles we've taken our Acura Mdx to the dealership for regular oil changes. Almost every visit results in a bad battery. We've had the dealership replace a side mirror due to the electrical and several batteries as well. They've kept it for several days diagnosing issues but haven't to this day found out what's wrong with it. Now my back taillight stopped working, we bought another one and replaced it for it to work for a couple months and stop working again. Now we've taken it to another place for diagnosing, they have said the inter taillight assembly and wiring needs replaced. Seems like this has been the issue the entire 6 yrs we've been complaining. The dealership says they took care of the problem already, clearly this is a safety issue when driving at night especially. Having a taillight that works off and on is not my idea of safe or "fixed" according to the dealership.

43 Electrical System problem of the 2016 Acura MDX

Failure Date: 08/19/2024

While waiting to turn left from a busy street onto a highway, the engine seized. The car was unable to be moved from it's location in the center of the busy street with cars approaching quickly from behind and weaving around my stopped vehicle. I had the vehicle towed to metro Acura in montclair, CA and they confirmed that the connecting rod bearing had failed causing the engine to seize. They also confirmed that the vehicle is not part of the existing recall. The engine produced some rough noise prior to failing but otherwise did not provide any warning lamps or other messages.

44 Electrical System problem of the 2018 Acura MDX

Failure Date: 08/16/2024

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.

45 Electrical System problem of the 2019 Acura MDX

Failure Date: 07/23/2024

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.

46 Electrical System problem of the 2016 Acura MDX

Failure Date: 07/23/2024

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.

50 Electrical System problem of the 2022 Acura MDX

Failure Date: 04/12/2024

All safety system alerts appeared while driving on the highway saying there were failures with all of the safety systems. Electronic steering suddenly stopped working and vehicle slowed down forcibly until its stop in the middle of the highway. I had to call roadside assistance to get the car towed to the dealership. All error messages came on, the vehicle electric power steering,vsa , hill start assist,trailer stability assist problem, collision mitigation & vehicle kept stopping itself while driving, road departure.

51 Electrical System problem of the 2019 Acura MDX

Failure Date: 04/06/2024

Infotainment system randomly becomes unresponsive and the screens will go black. The dealership stated that my phone was causing the issue. This is not true as the issue has happened when my phone is not in the car, phone is in the car/connected via bluetooth, in the car/connected via apple carplay (wired connection). This could be dangerous during the summer as these screens control the temperature controls and some of the safety systems.

52 Electrical System problem of the 2017 Acura MDX

Failure Date: 03/22/2024

On highway and switching lanes. All of a sudden electric parking brake and all driver assist lights came on. Pull over light came on as well. Hit on left rear symbol came on. Was never hit just a close car on driver left rear side when switching lanes. Made it home and vehicle wouldn’t switch back into drive mode. Acura didn’t do its due process and assumed a new transmission was needed. Replaced and a month later electric parking brake sign starts flashing again. Now dealership is saying I need a new catalytic converter. Refused as I believe Acura has been incorrect about the diagnostic. They also stated my vehicle was in a collision and it wasn’t. They refused to check electrical issues and update software as these things are not in my control. It is my belief the car had a faulty collision warning which is causing other issues as well as Acura refusing to probably assist and diagnose without me continuing to be falsely diagnosed.

53 Electrical System problem of the 2024 Acura MDX

Failure Date: 03/18/2024

The contact owns a 2024 Acura Mdx. The contact stated the messages, "parking sensor failure, see the dealer," and the "brake performance failure, (brakes may be reduced, see dealer" messages illuminated. The front collision sensor would alarm the driver when there was no cause for the sensor to activate. The vehicle was taken to the dealer, who reset the computer systems and replaced the front bumper sensor. After having the vehicle repaired while the brakes were applied, the brake hold would fail, and the brakes would release. The vehicle was taken to a second dealer, kearny mesa Acura, 5202 kearny mesa rd, san diego, CA 92111, who was unable to diagnose the cause of the failure. The contact did notice that the tires were out of alignment; however, as a result, the brake failure no longer occurred. While driving at various speeds, the vehicle would surge forward as if it were going from 1st to 3rd gear immediately, and while decelerating to come to a stop. While driving approximately 5 mph in a parking lot, the vehicle suddenly felt as if shifted to 3rd gear. The driver had to immediately press the brakes to stop the vehicle. The vehicle was taken to a third dealer, Acura of escondido, 1502 auto park way n, escondido, CA 92029, the dealer who was unable to diagnose the cause of the failures. The vehicle was not repaired. The manufacturer was informed of the failures and opened a case. The failure mileage was approximately 9,747.

54 Electrical System problem of the 2017 Acura MDX

Failure Date: 02/21/2024

The sensor under the hood malfunctions causing the car alarm system to go off and battery to get drained. Multiple batteries were changed because initially the thinking was that the battery needed to be replaced. Car alarm would go off in the middle of the night (with a new battery) when parked in the garage. All the electrical systems and lights would start turning off and on as if the car is possessed. Manufacturer is aware of the problem. Many others are complaining on the internet. There are variety of hacks including rigging the sensor that are suggested. Dealer said the entire control unit had to be replaced for $1122. Repair was made. They said when they run out of parts (control unit) they also disconnect the sensor. So you have cars on the highways that are no longer appropriately indicating when the hood is down (shut correctly or whether it is a false alarm. I called the manufacturer they didn't take responsibility (case 14470102) with Acura/Honda.

55 Electrical System problem of the 2019 Acura MDX

Failure Date: 02/10/2024

After driving for an extended timeframe (approximately 3 hours, trip was traveling between des moines, iowa and kansas city, missouri) at highway/interstate speeds, upon slowing down from those speeds, the vehicle goes into limp mode and check engine light begins blinking. After pulling over and turning car off and on again, normal behavior resumes. This has happened both as I arrived in the kansas city area, and upon my return home to the des moines area. Depending on circumstances for when vehicle enters limp mode, there’s a significant risk of causing an accident. Dealer was unable to pull any codes and therefore is unwilling/unable to address the issue.

56 Electrical System problem of the 2018 Acura MDX

Failure Date: 02/07/2024

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.

59 Electrical System problem of the 2017 Acura MDX

Failure Date: 01/14/2024

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.

60 Electrical System problem of the 2024 Acura MDX

Failure Date: 01/09/2024

I have attached all my service records from Honda/Acura and the dealership motorworld which is located in wilkes barre, PA I had my first issue with the car in January 2024 with sensors malfunctioning. They we replaced a few times, repeated issue I had other issues that didn't replicate themself or show as an error code when I brought the car in. Issue accelerating or inability to accelerate on the highway in a middle lane w/ a tractor trailer on each side. One trying to merge into my lane. Noisy brakes, low breaks etc fast forward to March 2025, my number one complaint about these sensor issues is they would malfunction on me one day when I was driving. And I was always assured by the dealership it was good, the car was good, I was good. Acura felt the same. Well in April my steering malfunctioned while driving, the steering wheel locked as I was breaking for a red light, and I drifted off the road. Turns out my steering rack needed to replaced. It was fixed on 4/4 then on [xxx] with my children in the car, it did the same thing. Now they tell me it is the eps, electric power steering. This car spends more time on [xxx] and one day this is going to happen on the interstate and there will be fatalities. I have been screaming at Acura and the motorworld for months. Acura will not respond to emails (which I have kept) and every time I call the case manager assigned to me is not available. The few times months ago I did speak to someone they tell me the same things the automated email I get once in while that say my case is under review. All dates of occurrence and repair are in the service records I attached. They still have my car today, 5/8/25 so I do not have those to attach. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

61 Electrical System problem of the 2017 Acura MDX

Failure Date: 01/08/2024

I was driving on the interstate yesterday (1/8/24) and the transmission suddenly downshifted gears and also went to neutral. I managed to pull to the shoulder, but the sudden loss of power could easily have been life threatening at a more crowded time of day or in poor weather. The car was towed to mcdaniel Acura in columbia, SC (I was out of town) and problem confirmed. I also called my regular mechanic (a Honda specialist) and he said this was a known problem and referenced Acura service bulletin 19-003 which says to reload new software. Codes were: transmission code p0716 parking brake system u0401-68 parking brake warning light on blind spot warning light on why hasn't there been a recall on this??? it's a known problem and I could easily have been killed and hurt others. If not a recall, at least at least do something to alert owners so they can get it fixed proactively if they want, as opposed to breaking down on the side of an interstate for hours.

62 Electrical System problem of the 2019 Acura MDX

Failure Date: 01/06/2024

I was yielding to make a left hand turn , in the middle of the intersection, and my car turned off and wouldn’t turn back on. In addition the car occasionally jerks as I’m driving almost like if it changes gear. Sometimes I can’t get the car in park position I have to press the button multiple times. The recall going on right now can cause a fire crash or injury and they cannot replace the parts until April 2024 and I don’t feel safe driving my car.

63 Electrical System problem of the 2023 Acura MDX

Failure Date: 01/05/2024

Within a month of buying our 2023 Mdx the rear parking sensor stopped working. When we took it to the dealer (10/23) they were unable to get the part. Car sat at dealer waiting on part but we finally decided to just get car back. Within a week of getting it back (12/23) I turned the car on one day and on the screen every system that could fail was flashing on the screen- brake system, power steering, parking assist, etc. The car was not draining correctly as all these alerts flashing. We finally had to get it towed to dealer (could not even get car in neutral to get onto tow truck). Still waiting on the rear sensor part to see if this fixes all the issues.

64 Electrical System problem of the 2022 Acura MDX

Failure Date: 01/02/2024

I've recently been in touch with an Acura dealership about my vehicle's wireless charger not working. So shortly after purchase I made my complaint that the wireless charger pad is not charging my phone. They've replaced the pad but still not charging my samsung ultra 22+ unless the car is parked and sitting still. They've asked me to allow time for researching the issue and taken all the make model details from my phone. Well sadly a few other things recently became noticeable to me as well and I will be following up with the dealership to address them as well as I'm not satisfied with my truck and the many issues I'm experiencing. 1) jerked when coming to a stop to reverse into my driveway 2) a loud thud noise could be heard inside my truck although I had the radio on when switching from park to drive or drive to park. 3) car stopped kind of midway when reversing jerking me in the process leaving me wondering why or what was going on. 4) engine would rev to 7000rpm even though I was going less than 45 mins per hour. . . . Just baffling honestly.

66 Electrical System problem of the 2020 Acura MDX

Failure Date: 01/01/2024

I've experienced stop and stall issues with my vehicle three times and the Acura dealership said they couldn't locate but kept my vehicle for a few days and said it was the battery. I have a new battery but same issue occurred two more times. There is definitely an electrical problem with this vehicle's system. The radio randomly stops working, no sound or buttons stop at any given time and also heat/air buttons switch by themselves. Shift paddles sometimes does not slow down vehicle, in most cases it accelerates.

67 Electrical System problem of the 2020 Acura MDX

Failure Date: 12/16/2023

The failure mileage was 6,000.

68 Electrical System problem of the 2020 Acura MDX

Failure Date: 12/04/2023

I was on a bridge heading into a tunnel stopped due to traffic and the car shut off completely. The screen said to put the car in park and restart it. I tried several times and after a few attempts it started back up. This is the third time this happened. I had a recall when I purchased it and had the recall addressed for the same issue. Now I am back at Acura again. And being told I may have to pay for diagnostics. The car is still under warranty.

69 Electrical System problem of the 2020 Acura MDX

Failure Date: 11/28/2023

While coming to a stop the engine start stop engaged causing the engine to turn off completely and would not restart when the throttle was pressed . The transmission shifted into neutral and the push button start would not fire the engine. Car would not go back to park. After locking and unlocking the door 30 seconds later it reset and the engine refired. This occurred with traffic flowing behind me and caused the car to be placed in neutral and the driver having no control over the vehicle. If this had occurred in an intersection while turning, the driver and occupants of the vehicle could be in significant danger of an accident. I took the car to the Acura dealer the next day and was told they had several complaints of this kind but would need to duplicate the issue on my car to assist me. If they could not duplicate the issue then the could not help me. At this time, it has not been inspected by the manufacturer. There were several warning lamps that came on when the car turned off.

70 Electrical System problem of the 2020 Acura MDX

Failure Date: 11/26/2023

Auto braking system engaged abruptly, without necessity. This occurred twice (December 2022 and November 2023) almost causing collisions on both occasions. The dealer could not reproduce the problem when it was brought in in December 2022 and said this could occur if the sensors are dirty and to ensure they are always clean. I have since done so, and the same thing happened again. There were no warning signs for this error prior to it occuring.
