Constant battery draining from unknown issue within the electrical system. I am currently on my third car battery after purchasing my car in january 2016 with 108 miles on the car. I have been using a portable battery jumper for the last month because of this on going issue. The car would not start after parking overnight and have caused a disturbance in my life before commuting to and from work, along with to covid19 vaccination appointments. Another issue is the auto start/stop function when pressing on the brake pedal at a red light where the engine is suppose to turn off and back on in order to be gas efficient. I have been forced to turn of the feature due to the car dying completely in at a red light and causing a traffic jam. It has happened multiple times and have caused additional inconvenience in my daily commute. I believe both issues are related and it is an issue with acura due to multiple individuals across the country when I have done research within acura tlx forums.

I was driving home from work on interstate I 84 in my car engine stopped. I pulled over on the side of the road see what was going on without power steering without power breaking and when I was on the side of the road and I tried to start my car in the vehicle was just clicking. Once I got the car home I tested the battery and I tested the alternator both of which are working fine the starter somehow shut my car off. This issue also occurs every time I use the automatic engine stop start at red lights keeping me from using that feature of my vehicle completely

Engine failed to restart during 'auto idle-stop/start' at a traffic light on a busy road. In order to restart I had to press the 'start' button multiple times and return the car to 'park' before being able to resume operation.
