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.
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.
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.

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.
