I have some serious issues with acura tlx with idle stop feature. My car had the same issues last year, when the car didn't turn back on automatically after the idle stop feature activated. I took my car to the dealership(acura of fremont, ca) and they can't able to figure out the root cause and my car battery died in the middle of the road. It took 3 -4 hours to take the car to the dealership and they replaced the battery but now this issue started happening again. I called acura customer service and they provided me this case number # [xxx] and forward the case to local dealership (acura of fremont, ca). I have dropped the car at the dealership but they are not very hopeful to find out the root cause of this issue. This issue is really a safety risk and not sure what you are planning to do to address this issue. It's seems to be a known issue with idle stop feature. Https://www.tlxforums.com/threads/engine-failing-to-start-after-idle-stop.31809/ I am hopeful that you will address my concern. Please feel to reach out to me at [xxx].

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 vehicle has had repeated battery failures. I had to have a battery replaced in this car less than a year ago and yesterday, the new battery died again. I was at the gas station getting gas and when I tried to start the vehicle, all of the lights started flickering with a loud repetitive clicking sound and the vehicle would not start. I had to call acura roadside assistance who sent out a aaa tow driver. The tow driver said that he has had about 80 calls for this type of vehicle just this year alone and all of them have had battery issues. Acura should issue a recall for these defective batteries. I have the vehicle at an acura dealer for the 2nd time in a year to have the battery replaced. The vehicle is still fairly new with only 46,000 miles.

While traveling 75 MPH on interstate multiple / all warning lights suddenly illuminated on dash board and the car placed itself into neutral from drive position. Upon coming to rest car was placed into park along shoulder and when drive was selected it would not engage. Vehicle was turned off and allowed to sit for several minutes before restarting again. Again it would not allow to go into drive. Tow truck was dispatched and after about 30 minutes car was able to shift into drive. Vehicle was then driven about 1/8 mile along shoulder to visible rear stop entrance. We waited for tow to truck to arrive. Car was restarted and would not engage into drive or neutral when attempting to load onto tow truck. After several attempts neutral and drive eventually engaged. Car was taken to nearest dealer just before close before major holiday. Recieved call from dealer stating that the cause of all this was dead battery. Unknown to them battery was replaced y months prior. Also I have dts report showing multiple malfunctions and errors. I feel that if all this can happen by having a dead battery (that somehow allows you to restart your car multiple times after initial malfunction) this is a huge safety concern. I called dealership back and asked them to double check diagnosis and also check alternator being that the battery is only 6 months old.

Driving on the expressway at 70 MPH, the car starts sputtering then decelerated, it would not accelerate even while pressing the gas pedal. I pulled off to the emergency lane and the lights started flickering, warning lights appeared "check hill start assist system", "check emission system", "check power steering system", "check brake hold system", "check brake system", and "check parking brake system". After sitting in the emergency lane after about 30 seconds, the car shut off. Extremely dangerous situation. It was diagnosed as a battery with a dead cell. Amazingly, of all the lights that illuminated, I never received any warning that I had dead battery. The battery light did not come on until the other warning lights came on. This happened at 35,246. This is the second time the car has been at the service center in less than 10 months.
