| Jul 2026 | ENGINE | I had driven 1.5 hours of highway driving. Exited highway and at the first stop light the car stalled on a busy four lane road. I have had the recall software update. Took a minute or 2 to get the car restarted | Crash: No Fire: No | Unknown |
| Jul 2026 | ELECTRICAL SYSTEM | Auto start-stop system stalled car at a light, could not turn car off after multiple tries following instructions on dash, but ultimately finally turned off, and then struggled to turn back on, all while on a busy road during rush hour. | Crash: No Fire: No | Unknown |
| Jul 2026 | ELECTRICAL SYSTEM,ENGINE | I was stopped at a red stop light waiting to turn left when my 2025 Acura MDX engine auto-stopped per the auto-stop feature. When the light turned green, I removed my foot from the brake and pressed the gas. The engine did not auto-start and displayed a message on the dash telling me to depress the brake and press the ignition button to continue driving. I did this several times, each time the dash would go black for a few seconds then come back up with the same message. Eventually, after getting the car to completely turn off, waiting 30 seconds, and restarting it, I was able to get the engine to start. While all of this was happening, I was passed unsafely by several angry drivers who were behind me, including one who tried to cut around me after I was able to get the car restarted, nearly clipping the front-right corner of my vehicle. I have an appointment with the dealer to have the issue investigated, but the appointment is not for another week. There was no indication of trouble prior to the first time this occurred. We have had this issue at least three times in the past week. | Crash: No Fire: No | Unknown |
| Jul 2026 | ENGINE | On June 9, 2026, my 2025 Acura MDX, with only 9,139 miles, stalled at a red traffic light after the Auto Idle Stop feature activated. The engine would not restart, leaving the vehicle disabled in an active traffic lane. I was unable to shift the vehicle out of Park and was stranded for approximately 5 to 10 minutes with my two young children in the back seat. The dashboard instructed me to fully depress the brake pedal and press the ENGINE START/STOP button to restart the vehicle, but repeatedly following those instructions did not restart the engine. There were no warning lights or other symptoms before the incident. I feared another vehicle would rear-end us because I could not move the vehicle out of the travel lane. After multiple attempts to turn the vehicle off and back on, it eventually restarted, allowing me to drive home. The vehicle was towed to the Acura dealership on June 10, 2026. The dealership inspected the vehicle, diagnosed a failed starter, and told me the failure was caused by the Auto Idle Stop feature. The starter was replaced, and I was instructed to disable the Auto Idle Stop feature every time I start the vehicle to help prevent the problem from happening again. The dealership has records of the repair, and the vehicle is available for inspection upon request. | Crash: No Fire: No | Unknown |
| Jun 2026 | ENGINE | The contact owns a 2025 Acura MDX. The contact stated that while stopped at a red light, the vehicle suddenly lost automotive power. The message, "Transmission System Failure - Apply Parking Brake while Parked - See Dealer," was displayed. The gear shifter indicator warning light was occasionally illuminated. The contact stated that while attempting to use the Push-To-Start feature to start the vehicle, the engine hesitated while turning over. The vehicle was taken to a local dealer and was diagnosed with starter failure. The vehicle was repaired under warranty. The manufacturer was not made aware of the failure. The failure mileage was approximately 10,000. | Crash: No Fire: No | 10,000 |
| Jun 2026 | UNKNOWN OR OTHER | Idle stop not functioning properly. Will get to a stop, and numerous times it will not start back up until you put it in park and restart it several times. Sometimes, it will not start on the 1st try from a cold start, or the starter will grind really slow. We have taken this to Acura several times, and they tell us it is a known problem, but just to turn the idle stop off each time. | Crash: No Fire: No | Unknown |
| Jun 2026 | POWER TRAIN,UNKNOWN OR OTHER,ENGINE | No restart after auto idle stop - Car fails to restart automatically after stop and releasing the brake pedal. This has happened on a number of occasions in the last few months.This can cause a dangerous condition that can can cause an accident if stopped in an intersection or a rear end collision as the driver behind assumes the vehicle will move but does not. Car has to be shut off to restart. | Crash: No Fire: No | Unknown |
| Jun 2026 | ELECTRICAL SYSTEM,ENGINE | 2025 Acura MDX will turn off with the auto on/off feature at red light but has had issue several times with turning back on. The car turns completely off and have to push start button to turn back on. On one occasion the same issue happened but would not immediately start with the push start again. | Crash: No Fire: No | Unknown |
| Jun 2026 | SERVICE BRAKES | Brakes are too soft . Hard to bring the car to a halt without crashing unless you are at very long distance . Brakes engage at a very low level . Dealer says everything is OK and can't do anything about it . Car is dangerous to drive. | Crash: No Fire: No | Unknown |
| Jun 2026 | ENGINE,FUEL/PROPULSION SYSTEM | Randomly when auto/start stop feature engages and shuts down the engine when I let go off the brake the engine doesn't restart and a system problem message show up on the dash. Have to shut down the car and restart for the engine to start running again. | Crash: No Fire: No | Unknown |
| Jun 2026 | UNKNOWN OR OTHER | The Auto Start/Stop system shuts down the engine and periodically the engine fails to restart. The car needs to be put into Park and then the electronics seem to re-boot before the car will restart the engine. This has now happened many times in city traffic, interstate highways and in areas of questionable safety (high crime zones). The dealer and Acura has refused to repair since they have not been able to duplicate the issue. They wanted me to lend my new $60,000 car to their service technician to drive back and forth from home/work to see if they can duplicate the issue. The dealer has tested the battery, however it passes. They refuse to do anything with the starter or other components of the system whether it be replace or inspect them. As the car ages (now approx. 1.5 years) it seems to occur increasingly often. I am concerned that the Auto Star/Stop system is doing irreparable damage to the engine & transmission. Additionally, sometimes the engine gets cut off and then tries to re-start and after several churns the engine restarts and the car lurches forward as the car is in gear "drive' when the car re-starts. The catalyst for making the car re-start is to release the brake... and that causes an immediate lurch forward when the engine does re-start. Does not seem to be a good thing for the transmission. The Auto/Start/Stop engine feature can not be permanently disabled. | Crash: No Fire: No | Unknown |
| May 2026 | ENGINE,FUEL/PROPULSION SYSTEM | My Vehicle is having an issue with the idle stop feature. Multiple times when stopped at a red light or when idle the car stops and will not turn back on. I have to turn the car off completely open the door to simulate leaving the car, wait a minute then start the car again to be able to move. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE | the car shuts off at a red light, fails to auto-restart, forces the car into Park, and requires a full manual reboot or jumpstart while stuck in moving traffic. It also struggles to turn on at times mimicking a drained battery. I am needing to deactivate the auto start/stop feature in order for the vehicle to properly function. Vehicle will not start when parked at times. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE | Description of Incident: While stopped at a red light at a busy intersection near a shopping district, the vehicle's Auto Idle Stop (AIS) system engaged and shut off the engine. When I attempted to restart by pressing the brake pedal — as instructed — the vehicle failed to restart. The dashboard displayed an error message reading "Idle Stop Function: Press Brake to Restart." My foot was on the brake pedal at the time; pressing it did not restart the engine. I then manually shut off the vehicle using the Engine Start/Stop button and attempted to restart it. The vehicle would not start. I remained stranded at the intersection for approximately 10 minutes. I had to call the cops for a patrol car because other cars were piling up behind me and I had my 6 month old son in the vehicle. Safety Impact: During this time, I was unable to move the vehicle from a live traffic intersection. This created an immediate safety hazard to myself, my family, and other drivers. | Crash: No Fire: No | Unknown |
| May 2026 | ENGINE | While stopped at a red light at a busy intersection near an airport, the vehicle's Auto Idle Stop (AIS) system engaged and shut off the engine. When I attempted to restart by pressing the brake pedal — as instructed — the vehicle failed to restart. The dashboard displayed an error message reading "Idle Stop Function: Press Brake to Restart." My foot was on the brake pedal at the time; pressing it did not restart the engine. I then manually shut off the vehicle using the Engine Start/Stop button and attempted to restart it. The vehicle would not start. I remained stranded at the intersection for approximately 10 minutes before the vehicle finally restarted and allowed me to shift into Drive. I was the first car in the lane, so people kept piling up and honking behind me. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE | The auto idle stop feature will kick in at red lights, shutting the engine down. However, every approximate 1 out of 10 times the engine and electrical system fully shut down when I try to start the car moving again. The car can then not be restarted for close to a minute. This results in not being able to move when the light turns green and is dangerous is heavy traffic areas. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | Car engine turns off at a red light, by turn off I mean completely turned off, not just silent. And takes a couple of attempts to restart the car before the engine turns on again. This has happened over 5 or 6 times over the last 3 months, however yesterday (May 9, 2026) it happened twice within the hour. Luckily, I have not been involved in an accident because of this, but I'm concerned that it's easy to imagine a scenario where someone will be rear-ended. Please issue a safety recall for Acura to fix this issue. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE | Last year, my 2025 Acura MDX was repaired under warranty for a known starter issue that is affecting all 2025+ MDX models. The issue is that the vehicle will stall or fail to start on random occasions leaving drivers stranded or stopped in traffic unable to move their vehicle. Honda and Acura are well aware of the fact that this is an issue, yet they continue to produce these vehicles with the same parts. This repair took several attempts and the dealership refused to even diagnose the issue for several months causing me to have to record each instance on my phone for proof. Once they eventually replaced the starter, the issue went away for approximately 10 months. Today, however, I was temporarily left stranded at a gas pump as my vehicle would not start. Honda and Acura dealerships are replacing these parts with the exact same part number, so the no-start condition comes back in about a year or less. It is incredibly dangerous to have a vehicle that you cannot move as anticipated, or if you’re in an area that you cannot leave or get away from potential danger because your vehicle won’t start. This is a less-than two-year-old vehicle that has now left me stranded on several occasions including in the middle of traffic on a motorway. I know for a fact that several other owners of the Acura MDX are having the exact same issue and ask that you please launch an investigation into this as Honda is well aware of it and still refuses to address the blatant safety risk it poses to its customers. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | While stopped at a traffic light, the vehicle had auto shut off normally. However when I released the brake and pushed the gas it unexpectedly stalled and shut off without warning. When attempting to restart the vehicle, it would not start again. There were no prior warning indicators or messages suggesting an imminent issue. This created a hazardous situation as the vehicle was disabled in an active traffic lane. After several attempts, the vehicle either restarted after having set the emergency brake. The failure appears to be sudden and without driver input, raising concerns about reliability and safety in traffic conditions. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE,LANE DEPARTURE | Engine stalls when at intersection and the engine cuts off at idle and fails to start back up when you remove your foot from the break. Can have keep lane assist enable. KLAS mode narrow, you have to fight the wheel to maintain control of the vehicle, formal mode is a 50/50 chance it works, wide you can sift right off the road for 5-10 secs before to realize your off the road. Steer wheel control button intermittently fail and stop being able to control the midi instrument panel and infotainment system. I believe there is a systematic electrical issue in the car. They attempted to fix this by replacing a starter which hasn’t because the engine stalled at an intersection again and on cold start this morning 5/4 at the same intersection as this is by my girlfriends apartment. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE | Vehicle is equipped with start stop system and we have had multiple instances where we come to a stop , and the car will not restart. In the latest instance, we pulled up to stoplight, the start stops system engaged shutting off the engine then wouldn't restart. Car also wouldn't turn completely off, so I had to hit the flashers at the busy intersection, try to get the car into park, then shut completely down, then restart the car. It also struggled to restart as if the battery was dying. In this instance most dash lights come on, but it appears to be an engine, electrical, and software issue. The vehicle has been inspected by the dealer multiple times, and in once instance they said the issue was caused by a bad battery, mind you the car is slightly over a year old. This latest time, they claimed that the battery was good and no issues were found. This issue continues to put me and my family at risk by leaving us disabled in the middle of traffic especially when it has happened near exiting the freeway, | Crash: No Fire: No | Unknown |
| May 2026 | ENGINE | I am reporting a serious safety defect involving repeated engine stalling and failure to restart associated with the auto idle stop/start system on a 2025 Acura MDX. The vehicle was leased in December 2024. Beginning in late summer and early fall of 2025, the vehicle intermittently shut off at stops and failed to restart when releasing the brake. This resulted in the vehicle becoming unresponsive in active traffic conditions, creating a significant safety hazard. The vehicle was presented to an authorized dealer for this issue on multiple occasions: August 15, 2025 September 9, 2025 October 31, 2025 After repeated unsuccessful attempts to diagnose and repair the condition, the dealer ultimately replaced the starter on October 31, 2025. This repair did not permanently resolve the issue. In April 2026, the vehicle again began exhibiting hesitation and delayed engine restart following auto idle stop events. On April 30, 2026, the vehicle stalled again, demonstrating that the defect persists despite prior repair efforts. This condition is intermittent and unpredictable, which increases the risk, as the vehicle may fail to restart when entering or crossing intersections or when moving with traffic. The inability of the vehicle to reliably restart creates a clear safety concern. Given the repeated repair attempts and recurrence of the defect, this appears to be a systemic issue rather than an isolated component failure. | Crash: No Fire: No | Unknown |
| May 2026 | STEERING | The contact owns a 2025 Acura MDX. The contact stated that while having routine maintenance, the power steering was making an unknown abnormal noise. The steering was turning on and off. No warning lights were illuminated. The vehicle was taken to the local dealer but was not diagnosed or repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 15,027. | Crash: No Fire: No | 15,027 |
| Apr 2026 | ENGINE | The vehicle is designed to shut off at a stoplight and restart when your foot leaves the brake, or the steering wheel is moved. On multiple occasions, the vehicle turns itself off (typically at a red traffic light) only to not restart. Driver must manually put the vehicle into park, and try to restart it using the traditional push button (IN TRAFFIC). This is horribly dangerous even if it takes just a few seconds to do. The Acura dealership maintains that there is nothing they can do. Simple internet searches indicate that it's a wider issue than my own vehicle, so I am reporting my issue to you. | Crash: No Fire: No | Unknown |
| Apr 2026 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | We have had multiple incidents when the car is at a stop light with the idle stop not active, the vehicle engine will just die. The light turns green and the vehicle is not running, it will take multiple times pushing the start button for it to start back up. This has resulted in multiple almost rear end incidents due to other drivers assuming we would go when light turned green. More recently this weekend on a trip from Columbus OH to St. Louis MO; stopped to get gas east of Indianapolis, after pumping gas the vehicle would not restart. It took multiple tries to get it to restart; this happened again the following day at a stop during the day at a shopping center, we ran in to get subs for lunch, came back out, would not start, I have a video of the sound and flashing lights but I can't upload a video here. | Crash: No Fire: No | Unknown |
