The windshield washer fluid pump is weak and half the time does not spray when needed and left me on the highway with a dirty smeared windshield nearly making it impossible to see while driving. I understand it’s a known issue and also a new pump and reservoir is on backorder after checking with dealer.. I believe it’s a poor design and a revision should be considered as this is a safety hazard. Thank you !!

I was at a red light. My auto idle kicked in. I went to turn it off and Either simultaneously or right before I hit the idle off button my car stalled. It took several attempts to turn back on and a bunch of codes threw. I almost got rear ended. This is a known problem. Ive contacted acura / honda via email as well.

- #11705339December 16, 2025BACK OVER PREVENTION: WARNINGS
I am a three-time Acura owner currently leasing a 2025 Acura MDX through Honda/Acura. On or about 12/02/2025, at approximately 16,297 miles, a front parking sensor fell out of the front bumper while I was driving. I am concerned that this reduces the reliability of the front parking/safety system and could put safety at risk if a driver relies on the sensors to detect obstacles at low speeds (parking, maneuvering, etc.) while the hardware is no longer properly secured. There was no crash or injury in this incident, but the failure affected a safety-related system on a low-mileage vehicle. Before I noticed the sensor was missing, the front alert on the dashboard began going off repeatedly while I was driving, even though there was nothing in front of the vehicle. That was the first indication that something was wrong with the system. Only after I parked and inspected the front of the vehicle did I see that the front parking sensor had come out of the bumper, which confirmed the source of the problem. The problem was inspected and confirmed by an authorized Acura dealer, who diagnosed broken internal mounting clips on the front sensor. The dealer and manufacturer attributed the failure to “outside influence” (implying that I must have hit something), but no impact damage or other physical evidence was found on the front of the vehicle. The front remains normal and pristine with no dents, cracks, gouges, chips, or distortion of the bumper, paint, grille, or sensor area. I am concerned that a likely part or installation failure on a low-mileage vehicle is being dismissed as “outside influence” based purely on assumption rather than documented physical evidence. In effect, an unproven assumption is being treated as fact, which could allow similar front sensor or mounting failures on other vehicles to be written off as external damage instead of being investigated as a potential durability or design issue with the front sensor mounting.

This has happend twice in the past 2 months, I came to a red light and the auto stop/start engaged automatically. When the light turned green and the vehicle was supposed to engage it turned off completely, all lights on the dash came on and it and wouldn't restart. Had to open the drivers side door and try to restart the vehicle, it restarted after a few tries. Very dangerous intersection I was stuck in. I have informed Acura of both occasions, they tested the battery cells and confirmed the battery was okay, was told this is a "known" issue with no resolve.

i purchased the vehicle March of 2025. Since I have been to the dealership on multiple occasions. I was there less than a week after purchase because there was a noise coming from the front tire the dealership balanced the tire. The noise was still there so i returned and the next time they replaced the front wheel bearings. I still have issues with the steering wheel shaking so they replaced all 4 tires. The problem still persists but they don’t know why. the car feels unsafe to drive especially on the highway and in rain. i have had the recall for the brake pin assembly addressed and fixed. I also have issues with the audio shutting off or not responding the dealer did a hard reset and an update to the software that has not resolved the issue. The car would turn off at random times and struggle to turn back on when the idle shut off was activated. the dealer replaced the starter. i have had issues with the car randomly braking when there is nothing in front of me and other safety features either not working at all or working when not needed. dealer advised it was a faulty battery and replaced it. I currently am still having shaking with loud noises especially at higher speed. The engine is very hesitant when accelerating and i struggle to merge onto the highway. It is also extremely jerky at lower gears and its most noticeable in stop go traffic. The brakes are squealing already and the mileage is low. I also sometimes need to press the brakes hard to even stop. The screen often goes black or will not connect to anything and i am unable to see directions or hear music. i feel extremely unsafe in this car and have anxiety every time i need to have anyone in the car with me

The idle-stop function would frequently malfunction. I would be at a stop, which would trigger the idle-stop function and the car would turn off, but when I released my foot off the break in preparation for needing to start moving, the car would stall and shut completely off. There was about a five second delay before I could get the car to turn back on and start moving, which was very scary with traffic all around me. After the malfunction occurred several times, I would try to remember to turn off the idle-stop function using dynamic mode. I called my local Acura dealership about this problem and the service manager said that he wasn’t sure what was wrong nor did he know how to fix it. He advised me to just wait and hope that Acura issues a recall for the issue. Then, I started noticing that there was a delay in my vehicle starting when pressing the start button. It wasn’t too long of a delay but enough for me to notice. Since the car would ultimately start, I didn’t think too much about it, until my car failed to turn on. It has happened when I turn off my car but then need to turn it back on soon after turning it off. I’ll press the start button and the lights on the dash come on and I can hear the engine trying to turn on but it doesn’t. The engine won’t crank up. I have to let it sit for a few seconds (30 sec?) and then try to turn it on again, at which time I have been lucky that it will turn on, but the initial start-up sounds like a struggle. It doesn’t sound like a healthy start up for 2025 vehicle.

My 2022 Acura MDX A-Spec developed an electrical problem where I heard an extremely loud pop come from the stereo system before it stopped working and then the infotainment screen stopped working as well. I took it to the dealer who determined that a water leak in the sunroof drain plug caused the interior of the vehicle to become saturated with water and cause corrosion to electrical bundles. By searching the internet, I found that this was a known manufacturer’s defect with this specific model that had been made known to the dealership and they did nothing about it. Having an electrical problem could have put us at risk had things stopped working at an inopportune time on the highway or caused a malfunction at a critical time while driving. I submitted a request to Acura for an extended warranty of this problem, but that request was denied. They said that there had been an extended warranty for this issue, but that it had expired somewhere between March 2025 (when my normal warranty expired) and October 2025 (when I took it to the dealership for an evaluation of this problem). Acura wouldn’t say when that was, but I was surprised that they were of no help. As I mentioned, this is a known manufacturer’s defect that should have been checked per my normal maintenance visits, but it was ignored until it became an actual problem. They certainly could have been more proactive and it would have saved us a lot of time and expense.

As I was turning right (slowly accelerating from a complete stop) into a shopping center parking lot, I was entering into the lane behind a vehicle that had just passed in front of me (and was headed in the same direction I was going to turn). My 2022 Acura MDX Low Speed Braking Control system engaged for no reason. The breaks slammed hard bringing the car to a hard, sudden stop, and I thought I had been rear-ended by the car behind me. I pressed the gas slowly again and was able to pull into a parking spot and checked my back bumper…PERFECTLY FINE! I googled the issues I experienced and found this is a common problem! This is a dangerous problem! Please hold Acura accountable to fix this issue! For now, I have to remember to turn this Low Speed Braking Control System OFF EVERY TIME I power on my MDX! I am now scared to drive my car!

When the car comes to a stop, the engine will shut down after idling. This is by design. The problem is that the engine shuts off and does not start up again. This is very dangers when turning across traffic. I took the car in for maintenance and they said this is a known issue but there is no fix. The internet has many complaints and some people are having their starters replaced. This problem has occurred in other model years of this car. Please issue a recall and make Acura accountable for this known issue.

When the vehicle decelerates—either from high speed or while already moving slowly—it frequently jerks just before coming to a complete stop. This issue is especially noticeable at very low speeds or during final braking, where the vehicle may lurch forward by a few inches unless the brakes are applied firmly. Despite multiple visits to the dealership, including transmission resets and software updates, the problem persists. The dealer has not provided a resolution or adequate follow-up. This behavior poses a serious safety risk, particularly in high-traffic areas where precise stopping is critical.

2026 Acura MDX with Acura Factory A Spec issued plastic floor mats. Accelerator pedal gets stuck behind the floor mat resulting in uncontrolled wide open throttle. Had to physically put my foot behind the pedal and pull pedal away from floor. Afterwards tried a few times to repeat the issue, 3/5 times was able to reproduce stuck pedal. Top of the drivers plastic floor mats, right side, has a U cut out for the accelerator pedal. This needs to be trimmed another 1/2” or more to stop the issue. Could result in severe or fatal consequences.

AC / DEFROSTER / HVAC I am reporting a potential safety and health defect involving the HVAC system in my 2024 Acura MDX. When operating the air conditioning or the front windshield defroster, a strong musty odor enters the cabin. The dealer informed me that resolving the odor requires an EVAP core cleaning, replacement of the cabin filter, and the use of a disinfectant that will be circulated throughout the ventilation system to kill mold, mildew, and other contaminants. I was told this is the “first step” in addressing the issue and that the estimated cost is $440 out of pocket. This is extremely concerning because the presence of mold or bacterial contamination inside the HVAC evaporator and ventilation system affects the air my children and I breathe inside the vehicle. Mold exposure can cause respiratory irritation, allergic reactions, headaches, and other symptoms, especially in enclosed spaces. The HVAC system in this vehicle is a sealed, manufacturer-controlled system which the owner cannot access or service, so this type of contamination should not be considered routine maintenance. I have researched this issue and found that Honda/Acura vehicles have a documented history of HVAC mold and mildew odors, and Honda has previously issued internal investigative bulletins requesting dealers to collect parts from vehicles with musty HVAC smells. There are also mold-related complaints already filed with NHTSA for the 2024 MDX model year. This suggests the possibility of a broader engineering or design issue. I need this issue addressed immediately for health reasons, and I may have to initially pay out of pocket to ensure my family’s safety. However, I believe this is a safety-related defect that Acura should be responsible for correcting, not the customer, especially on a relatively new vehicle still under warranty. I am requesting that NHTSA document this case and consider evaluating whether a pattern of HVAC mold contamination exists in newer Acura vehicles.

The start/stop switch stalls the vehicle and will not restart after several tries for up to 5 minutes. We get a message during this time to "continue to drive, depress brake pedal and push switch" and even after then it still will not start for several tries. This has happened several times. One time my wife was on a heavily traveled two lane farm road at a four-way stop and it did it and was almost hit by 18 wheelers trying to navigate around her. This was not only a safety issue for her but also those trying to get around her with all the traffic coming in all direction. Took back to the dealer but it did not do it while they tried to recreate the issue. No warnings prior to the issue of dying and not re-starting. This was the latest occurrence, it had happened a couple of times before.

When the auto idle stop system is enabled my Acura will shut down completely when the vehicle comes to a complete stop and the idle stop system will not reengage as it should when your foot comes off the brake and the car shuts completely off and goes into park. This has happened 3 times, the last one occurring on a very busy highway, and I'm thankful I wasn't rear ended by the car behind me. Traffic had to go around me which caused quite a hazard pulling out into a fast moving lane. It finally responded, restarted and I was able to move forward. It was taken into the dealership and they weren't able to recreate the occurrence for the short time that they had it (one week). There was no warning prior to failure. I have called Acura Client Relations and they turned it over to their Management team, gave me a case number and I haven't heard from them as of this complaint. Reading your website I see many others having and reporting this same dangerous experience with their 2025 Acura MDX.

As slowing down to park in parking space, the automatic braking applies hard and throws you forward. All three times, the vehicle was just entering the parking space and automatically slammed on brakes causing all passengers to lunge forward and seat belt to apply hard, hurting passengers chest. This is a safety hazard as it could cause harm to the passengers and if it happens at higher speeds then could cause a rear end collision if someone is behind us when this happens. This has happened three times in the past month. We have also experienced the cruise control not working once because it though there was a car in front of us when there was not. I turned the cruise off then on and has worked properly since.
