problem #7

The car failed to turn back on after the auto stop fuction turned the engine off. This left me stranded at a green light. After a few seconds the car put itself in neutral and I slowly coasted to the side of the road as I was on a hill. It would not start for around 30 seconds, remained in accessory mode with the engine off. Finally it started and I cautiously drove home. The oil and coolant levels are still perfect and I got the battery tested. Not sure why it would not start back up.

The Idle stop feature will NOT automatically restart and causes me to stall for an unsafe amount of time. There is a recall call for my Acura 2018 TLX but my VIN does not fall under the qualifying vehicles. I am very upset and this is a safety matter that needs to be addressed ASAP.

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/
