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.

Idle stop causing engine to shut down. This has happened three times! It’s very dangerous.
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.
