| Feb 2026 | ENGINE | My 2025 Acura MDX (under 10,000 miles) has failed to restart after the automatic idle stop engaged at stoplights and drive-thru lines at least 7 separate times. When I release the brake, the engine often remains off and the vehicle will not move, leaving me stopped in traffic. I have not yet required a jump start, but on several occasions the vehicle came very close to not restarting at all. This most recently occurred at a sandwich shop drive-thru. These incidents occurred in normal drive mode and in normal weather conditions. No abnormal driving conditions were present when the failures happened. Other owners online report the same problem, with some needing to carry jumper cables. I believe this is a serious safety risk because the vehicle can stall unexpectedly in intersections and traffic when the auto stop-start system activates. I am now concerned about relying on this vehicle in traffic because I cannot trust it to restart when stopped. | Crash: No Fire: No | Unknown |
| Feb 2026 | ELECTRICAL SYSTEM,ENGINE | Auto Idle Stop/Auto Start-Stop Issue- On multiple occasions, occurring randomly, the vehicle will not start at stoplights after auto-idle stop is engaged. Sometimes this happens after the vehicle has been running for over an hour. Currently, the vehicle must be completely powered down and then restarted to revive engine. | Crash: No Fire: No | Unknown |
| Jan 2026 | UNKNOWN OR OTHER | Sunroof exploded while driving on the interstate. A loud noise and glass was everywhere inside the truck on my passenger and I. The distraction caused me to slam on brakes injuring my foot in which I’m out of work for 4 weeks | Crash: No Fire: No Injuries: 1 Medical attention | Unknown |
| Jan 2026 | ENGINE | When stopped at a red light on a busy off ramp to a busy highway, the car's engine idle function turned the engine off (as anticipated), but then upon releasing the brake, the car did not turn on. I was stalled in the middle of traffic, which is a significant safety issue. I had to turn the car completely off, wait a few seconds, and turn back on. this car is marketing for families with its third row and stalls when stopped. there are numerous reports of this on online forums. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM | Autostart (stop/start) stopped engine but failed to restart car. Had to shut down computer and restart computer and then car started. Cars were coming around blind corner serving to avoid us. Has since happened multiple times just starting up vehicle (not involving autostart). Taken to Acura dealership 3 times to fix, but they have been unable to resolve issue. | Crash: No Fire: No | Unknown |
| Dec 2025 | UNKNOWN OR OTHER | The auto start stop function is not working, the car turn-off completely and I have to start the engine by pressing the start button. | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Dec 2025 | BACK OVER PREVENTION | 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. | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE | 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 | Crash: No Fire: No | Unknown |
| Dec 2025 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Nov 2025 | FUEL/PROPULSION SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM,ENGINE | 2025 Acura MDX Aspec Advanced - Experienced 3 instances of failure to restart after engine idle shutoff or normal shutoff. Periodically starting the vehicle makes a buzzing or resistance type of sound, but usually will start. 1) 8/8/2025 Returning from shopping turned off vehicle in driveway to open hatch to unload items. Upon re-entering the vehicle (~5 mins) the push start failed to start - engine sounded sluggish first attempt and failed to start. Subsequent button presses just made a clicking sound. Had to fully turn off vehicle and back on and it started. 2) 10/10/2025 Returning from a wedding and getting off the expressway to a traffic light the auto stop/idle stop turned off the engine. Once the light turned green the vehicle failed to restart multiple times. Had to fully turn off vehicle and back on to get it to start 3) 10/30/2025 After parking for shopping, upon returning to the vehicle it failed to start from off. Any subsequent repress of the start button would make a click and starter failed to engage. after turning off vehicle and back on it started Vehicle was taken to dealership and notified of issues - they checked the battery and it was fine, no trouble found. | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM | The power and motor on the moonroof and sunshade has failed multiple Times in the first year of owning the car. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE | When the automatic engine start/stop is enabled, my car will shut down. To the point where it has to be completely off, then restarted. This has happened twice, the first time was on 9/28/2025 and the second time was on 10/29/2025. We were in traffic, and the car behind me, almost ran into me, as I stalled. the lighted symbols on the dashboard were illuminated during this experience, but I am not sure which ones, as I was in a panicked state given that my child was in the car with me and this almost caused me to get hit by car behind me. I have not had this checked by the dealer yet, but I am scheduling the appointment for as soon as possible. | Crash: No Fire: No | Unknown |
| Oct 2025 | UNKNOWN OR OTHER,ENGINE | Car engine sometimes does not restart when the auto start-stop feature is engaged. Car engine is also sluggish to restart when it does work. My local Acura dealer evaluated the car on 10/15/25, found battery was low. Battery was replaced that day, and things seemed okay for about a week. Today (10/21) when I was stopped at a traffic light, the issue returned and my car would not restart after going into auto start-stop. The car had been on for about 30 minutes. When I tried to restart the engine, it took three tries before finally turning over. Fortunately, this has only happened thus far for me at stoplights, but safety could definitely be impacted if the engine does not turn back on and the car needs to be maneuvered quickly. No warning lights or messages appeared prior to the issue. This started for me about 3 weeks ago. No accidents or known issues with the car prior to the issue. There does not seem to be a predictable pattern to the auto start-stop feature failing. | Crash: No Fire: No | Unknown |
| Oct 2025 | UNKNOWN OR OTHER | My 2025 Acura MDX randomly turns off when in Auto Stop/Start mode at stoplights and I have to restart it. After it happen twice, my husband took it to the dealer, and they could not find anything wrong with it. It happened a third time and this time the dealer kept it for a week. They found nothing so their system doesn't detect problems well. I had their loaner, a 2025 MDX A-Spec. I was driving the vehicle into a parking space at my office which faces a 4-lane highway. My foot was on the brake, and I was 2/3rds into the space. Suddenly the car lunges forward, revs up and takes off over the curb, over 3 bushes and down a sloped hill into the highway. I could not stop the vehicle! My hands were on the steering wheel and my foot on the brake as I was bracing for impact with another vehicle. Thankfully there were no cars in the lane! As I entered the right lane a car passed by me. The engine then revved down, and I was able to gain control of the car and pull into the parking lot. I have met with the managers at the dealership. They still cannot find what's wrong with my car as the computer doesn't show anything. They have run a test on the loaner car as well and said they could not find any issues with it either. They are calling in an engineer to inspect the loaner car. I or someone else could have been badly injured or killed! I feel the MDX A-Spec I was driving is a deadly vehicle, and I do not want this to happen to anyone else!! There were no warning messages or problems prior to the incidence My hope is that there would be an investigation into this vehicle and into Honda/Acura to see it there is safety issues with their vehicles. The photos are of the area the incident happened. The dealer has the vehicle. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Sep 2025 | FUEL SYSTEM, GASOLINE | The contact owns a 2025 Acura MDX. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond as intended, causing the vehicle to decelerate unintendedly. Several unknown warning lights were illuminated. An independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed, and determined that the throttle body was damaged and needed to be replaced. The vehicle was not repaired. The manufacturer was notified on the failure and suggested that the vehicle be taken to the dealer for assistance. The approximate failure mileage was 6,000. | Crash: No Fire: No | 6,000 |
| Sep 2025 | UNKNOWN OR OTHER,ENGINE | During three separate incidents, my vehicle’s engine unexpectedly shut off without warning, twice in the middle of moving traffic and once while idling in a drive-thru when the engine idle stop/start feature was engaged. In each case the vehicle did not immediately restart, leaving me and my family exposed to oncoming traffic and high-speed vehicles, especially once while exiting a highway. The malfunction appears related to the engine’s idle stop/start or fuel/ignition system, but no specific component has been identified; the vehicle remains available for inspection upon request. Although I reported the incidents to the dealership, they stated they could not reproduce the problem and therefore could not repair it. . No warning lamps, error messages, or other visible symptoms appeared before or during any of the shutdowns, the engine simply stopped running, so there was no advance notice before the failures occurred. | Crash: No Fire: No | Unknown |
| Sep 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | When driving and the stopping the auto start/stop feature does not rengage and the car places itself in park and becomes disabled and difficult to restart. When driving on a major highway when I was in traffic the car shut down, put itself into park and would not restart upon removing my foot from the brake. It then gave numerous error messages and would not respond to any commands. Traffic started moving and cars were then needing to go around my disabled vehicle. It finally responded to me trying to restart it. We had the car checked the week before it happened due to it being slow to re-engage when the auto start stop would be used. The dealership reported that there was nothing wrong. Brought it back after is was disabled on the highway for 5 minutes and they are still saying there is nothing wrong if they do not see it happen themselves. It is a danger to drive. | Crash: No Fire: No | Unknown |
| Sep 2025 | ELECTRICAL SYSTEM,ENGINE | While driving in traffic, my vehicle suddenly shut down without warning. The engine stalled, and I lost power to steering and braking, creating a serious safety risk for myself and other drivers around me. The problem has occurred more than three time. At the time of the failure, there were no warning lamps a message display showing to continue to drive depress brake pedal and push switch there was no check engine light showing. I had to shut the whole car off open the door and re start the car. The issue has been inspected on 08-13-25 by a acura dealer / mechanic. I was told it was the battery and it was covered under warranty. They found no other issues. The car shut down on me again on 08-19-25 and on 08-30-25 with my family in the car. This unexpected shutdown placed me in danger of a potential collision, and I am concerned that this may indicate a larger defect affecting this vehicle. I can get a receipt from the acura service department if needed. | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER | This is a known issue with Acura that they have not addressed. The software cannot be updated due to a flaw in their design. The dealerships cannot even update the software since it is designed to only be updated via a WiFi connection, which does not work. This is critical, because the 2025 MDX is actually a major departure from prior years in how the brakes and other functions operate. When I brake, it is very rough and uneven and the engine revs and surges the vehicle forward. Only a software update could possibly fix this, but this is not possible, due to the lack of any access to the car's electronics. Quite frankly, Acura marketed this vehicle to be vastly superior to prior year models, but they cut out various features (including a hard wire connection to the electronics). | Crash: No Fire: No | Unknown |
| Aug 2025 | ENGINE,FUEL/PROPULSION SYSTEM | Idle stop causing engine to shut down. This has happened three times! It’s very dangerous. | Crash: No Fire: No | Unknown |
| Aug 2025 | POWER TRAIN,ENGINE | The auto start/stop system failed to restart at a stop light. This was an issue on the older MDX and TLX vehicles with the 3.5L V6 which resulted in a large recall. The recall has not been extended to cover the 2025 MDX and the dealership is refusing to fix the issue or acknowledge it despite having a video to prove it occurred. Acura is knowingly selling these vehicles with a dangerous safety defect that will occur at random. Please consider investigating this matter further as I am concerned for my safety and the safety of my passengers. | Crash: No Fire: No | Unknown |
