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.

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.

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.

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).

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.

The geniuses at Acura / Honda quit installing SiriusXM in the 2025 MDX and instead relies on the user's cell phone paired to the "radio" to get SiriusXM. My issue is that it cuts out when my cell phone doesn't have a clear view of the SiriusXM satellite. Sometimes it continues when reception improves, but most times I have to reboot the SIrusXM app on my cell phone. This quite dangerous in traffic and definitely is not a safe action. I'm quite ready to change cars because I don't want someone to get hurt because of this design flaw. This has been happening since I bought the car in January but is getting more frequent with the foliage on the trees.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
