Four times in 18 months, with the most recent happening last month and today, I was at a stoplight and turned my manual idle off. The light changed and the car would not move despite me stepping on the gas. It told me to restart the car which I did but the first attempt didn’t work to restart. After a few minutes I tried restarting again and it struggled but did. I was very worried as there was a car behind me who thought we were moving with the green light and fortunately he moved to the other lane to avoid a collision as it took me a minute to figure out the car had stopped before putting in my hazards.

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

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.

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.

The vehicle will turn off when it comes to a stop without being put in park. This has happened on busy city roads, highways in traffic and residential areas at stop signs. The vehicle will also periodically not turn on, with multiple indicators lighting up on the dashboard. This has been reported to the dealership, who states if there are no active error codes or indicators at the time of service there is nothing they can do. I have opened a case with Acura client relations more than 3 weeks ago and have escalated multiple times with no response. This has created numerous safety problems, also with children in the vehicle. This vehicle is not safe to operate and the manufacturer refuses to respond to my intervention requests although it is under warranty.
