Electrical system, Fuel/propulsion system, Sep 8, 2026
Auto Stop/Start fails to restart intermittently causing dangerous situations stuck at lights unable to move. Sometimes it restarts again after pressing the brake and ignition right away. Sometimes it takes a minute to restart. Either way it happens unexpectantly leading to being frozen until you figure out what is going on.

After an auto idle stop at a major intersection, car failed to restart automatically and was left stranded unable to restart the car. Car would not shut off or turn back on when using the power button and with foot on brake but had power but it was in limp mode - transmission warnings flashed and the D "for drive" on the screen at the drivers location. I called tripleA however before they showed up I was able to put the parking brake on and turn the car off and on ad it reset. This is similar to the issue was happening with my 2017 Honda Pilot where it would stall and not restart after the auto idle stop engaged. Very dangerous and difficult to troubleshoot when in that situation, surprised that this is still happening in Honda manufactured cars - this is very dangerous and needs to be addressed and investigated.

My vehicle was stopped at a busy intersection, idling in the automatic stop mode. When my husband moved his foot from the brake to the accelerator, the car stalled, orange alarm alerts went off, and the car was completely dead and stalled without power. The car needed to be restarted, and it took a few attempts to accomplish that task. I have had the same problem before with this car and have had it into the dealer at least two times without resolution.

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.

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.

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.

Filters replaced, software updated Dec 2025 issue still occurring battery replaced March 2026 issue still occurring starter being replaced Technician at dealership did not seem confident that replacing the starter will remedy this issue.
Fuel/propulsion system, Nov 23, 2025
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.
