The car will stall. The auto start/stop does not turn the car back on. The car fails to start sometimes when trying to leave. We have almost been rear ended multiple times, the transmission stalls and will not “go” when you press the gas or the car won’t even turn back on. We have contacted Acura and a local dealer. Both say they do not have a remedy for this issue yet even though it’s part of the recall and keep pushing it off to the next season. Each time I call for an inspection, I get told there is nothing they can do. I ask about seeking legal advice and they just tell me they don’t have a remedy so a lawyer can not help me.

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.

After coming to a stop at a red light, the vehicle engine turned off as designed with auto start stop. When the light turned green, the vehicle temporarily restarted when I released the brake pedal, but immediately stalled and would not restart. This is a major safety concern as I was on a four lane road with traffic all around and I was unable to move. I had place the vehicle into park, turn off the ignition fully, and attempt to restart the car. It eventually restarted, but it took nearly 90 seconds. This is a danger to myself, and to the traffic around me as I was fully stopped on a road with 40 MPH limits and a lot of traffic.

Auto Stop/Start feature fails to restart vehicle, rendering vehicle inoperable. Powering off the vehicle and then powering up the vehicle thus far has restarted everything, much to the frustration of myself and the drivers behind me.

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.

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
