NHTSA Complaint #11459222 — 2018 ACURA TLX

Engine fails to start after idle stop, when the idle-stop off button is not engaged, and the battery doesn't have enough power to re-start the vehicle. Essentially, the engine tries to start up at a traffic light/intersection but fails, causing the car to turn off and shift to Neutral without warning. I then have to realize what is happening, shift the car from Neutral to Park, and hit the start button to be able to re-start the car. There is no warning from the car that the battery is going to be unable to keep the car running, so the stall is 100% unexpected. This is unsafe, as the re-start procedure is not intuitive, takes time, and causes cars behind you to start honking. It could very easily cause a crash. Either Acura needs to fix this issue with a battery warning, or provide the option of turning the auto-idle stop off button on permanently (which some members of our government wouldn't like, but would fix the problem and keep someone from being seriously injured). This is also a known issue by Honda/Acura, as many other owners are reporting it: https://www.tlxforums.com/threads/engine-failing-to-start-after-idle-stop.31809/
