The car does not restart after it has turned off during an idle stop. This is part of the start/stop system. The stop/start feature will leave you stranded at stoplights due to a failure to restart the car. To restart, you must put the car in Park mode and hit the start/stop button at least twice to turn it off, then turn on the car. This causes some panic when you get into the situation, as it is not the expected behavior. For people who are unaware can be put in a very challenging situation. This has happened multiple times in the past few months.

Idle stop system works properly 99.9% of the time. However, three times in the last 12 months, I was stopped at a light and when I took my foot off the brake the car did not start. I tried to re-start, but it did not start immediately, took about 10 to 20 seconds to start. In each of the cases, I was able to restart just not right away. These three instances were about four months or so apart. The system was checked by Acura service twice, and no issues found.

My car stalled for the second time on June 12, 2019. First time was March 31, 2019. Since I already got the recall notice (NHTSA recall 19V-060) before the first time, I took it to the dealer and they said they fixed the issue by doing a software update. However, even after the software update, it stalled again on June 12th, 2019. It looks like either a new issue or their software update did not fix it. There is also a possibility of the updated software having new bugs. In my car, the issue could be with the computer, or other electronics or mechanical defects which Acura has not been able to find out during my several visits to their service. This is because most or all features of the car have been malfunctioning eversince I leased it. Another big issue is, apparently, the car computer did not record the stalling that happened on March 31st. Therefore, it looks like my car has a bigger issue than just software. The car (2019 Acura Tlx) has numerous issues ever since I leased it in September 2018 and they all continue. I have taken it to the dealer several times and none of the issues had been fixed. All features on the car malfunction and cause distraction while driving. The safety features not only don't serve the purpose of safety, but malfunction instead causing distraction and are very unsafe. The car would have been safer without these malfunctioning safety features. Acura has not fixed any of these malfunctions, although I have visited the dealer several times. To top that the car stalled twice which is even more serious. Although, my appointment is for 6/24/19 (I could not get an earlier one since they don't seem to take it seriously), the customer service rep called me a few days after scheduling it and said she did not expect it to help. I will still keep the appointment, even though the rep indicated this stalling will be dismissed as nothing.

I live in Colorado and use paddle down shift to gear down for slowing on declines. When I do that, the car acelerares for a few seconds before slowing down. This is a very dangerous situation because you believe you are slowing to avoid running into the car in front and instead you increasing speed toward the back of the car in front. Acura customer service say that is the way the car is designed, but does not defend the logic of that design. I can not believe that this has not caused serious situations and accidents.
