I was on a bridge heading into a tunnel stopped due to traffic and the car shut off completely. The screen said to put the car in park and restart it. I tried several times and after a few attempts it started back up. This is the third time this happened. I had a recall when I purchased it and had the recall addressed for the same issue. Now I am back at Acura again. And being told I may have to pay for diagnostics. The car is still under warranty.

While coming to a stop the engine start stop engaged causing the engine to turn off completely and would not restart when the throttle was pressed . The transmission shifted into neutral and the push button start would not fire the engine. Car would not go back to park. After locking and unlocking the door 30 seconds later it reset and the engine refired. This occurred with traffic flowing behind me and caused the car to be placed in neutral and the driver having no control over the vehicle. If this had occurred in an intersection while turning, the driver and occupants of the vehicle could be in significant danger of an accident. I took the car to the Acura dealer the next day and was told they had several complaints of this kind but would need to duplicate the issue on my car to assist me. If they could not duplicate the issue then the could not help me. At this time, it has not been inspected by the manufacturer. There were several warning lamps that came on when the car turned off.

Auto braking system engaged abruptly, without necessity. This occurred twice (December 2022 and November 2023) almost causing collisions on both occasions. The dealer could not reproduce the problem when it was brought in in December 2022 and said this could occur if the sensors are dirty and to ensure they are always clean. I have since done so, and the same thing happened again. There were no warning signs for this error prior to it occuring.

Idle stop feature causes vehicle to auto shift to neutral at stop. There are many forums noting this issue. It happened a year ago several times, they replaced the battery and it is happening again. You are sitting at a light or stop sign, go to hit the gas, and the car is in neutral. You need to turn the car off and start again. This is a serious risk of getting rear ended with this issue. One time when it happened last year a cop pulled me over to see if everything was all right. The car should not be shifting to neutral at a stop.

Our 2020 MDX we lease has lost electrical 3x since Sep 1. Once while sitting at a stoplight. Twice while turning at intersection. Each time, there was a complete power loss. When the car was moving, it quickly slowed to a stop in the road. In each case, it took a few minutes to get the car restarted due to being startled at what happened. I checked the battery cables, and they are tight. The radio settings were not lost, so I do not think it was a battery connection failure. We are not sure what to do with this as, while there are a lot of similar reports for acuras, there is no consistent diagnosis.

2020 Acura MDX, bought this in February of 2021. Issue with the auto-idle completely turning off the engine, when you pull up to a red light or stop sign and the engine goes into Auto-idle, then go into neutral, sometimes showing the battery sign. The car is completely disabled, have to shut off the engine and restart. This happened about 3 times, the last time was with my 2 young children in the car and people honking at me!!!!! Brought it into Acura, when said it was battery issure and replaced the battery in Sept. 2022. August 2023, brought it in for 2 recalls, once was for the idle engine, they service person said the issue was fixed. October 2023, by car did not restart from auto-idle (AGAIN TWICE in less than a week), brought it in again, they said they couldn't find anything wrong with it! Just got my car back, called Acura headquarter, made a complaint!

Purchased used vehicle from dealership last week who completed the outstanding recalls prior to picking it up. Vehicle only has ~7800 miles. Stopped in traffic for red light, engine idle turned on after applying brake fully and car completely died...would not turn back on and nothing worked, not even hazards which made it a very dangerous safety issue sitting in the middle of a busy street. Police would not wait for call to AAA for free tow due to current safety issue and had it towed to local towing company.

This is happening for the second time. Exactly same thing happened for the first time as well. I stopped a light. The car went to auto idle and shut the engine off. I kept my foot on the break pedal until the green. When I release the pedal, the car didn't restart and it went to neutral. I pushed the drive button but it didn't change. I had to shut off everything by pressing the stop button and I started the car again. I think this also happened to other people based on the posts online: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Its a known issue with my 2020 Acura MDX it has an issue with the autoidle completely turning off the engine, so you pull up to a red light and the engine goes into Autoidle mode and then completely turns OFF the engine so you are stuck in the middle of the road for a few minutes and then you have to wait for the car to allow you to turn it back on. Acura is aware of the issue and sent a letter to consumers for a mandatory software update to fix the issues. After experiencing this, I took it to the dealership and they completed the software update to fix this issue earlier this year. But my issue is still happening and we got stuck in the middle of a road for 5 mins with a toddler and a teenager. Incoming traffic almost caused a collison because of this.

When putting the vehicle in "Drive" it unexpectantly rapidly accelerated causing me to aggressively brake the vehicle. It's happened twice and could easily have crashed into surrounding property or pedestrians. I brought the vehicle to the Dealership but considering it is an intermittent problem they couldn't duplicate the situation. Acura said they have no record of anything like this happening. There were no electronic lights or indicators that warned me of a malfunction. The first occurrence was several months ago, and the latest occurrence happened two days ago

Multiple times when I have come to a stop (traffic light, stop sign, etc.) my MDX has shifted itself into "Neutral" and it appears the engine has cut off by the battery power is still on, my MDX will not shift back into "Drive" or "Park"; I then have to press then "Engine On" button multiple times to get the battery power to shut off and then I can restart my MDX and then my MDX will shift into "Drive." I took it to my Acura Dealer and they said they checked it and there was nothing wrong and they also told me there had not been any recalls on my MDX.

We purchased a certified pre-owned Acura MDX 2020 in Feb of this year. In four separate instances, after the auto engine idle feature is on, the car stalls out and shuts off. Two of the four times this has happened on a highway causing extreme stress. When I lift my foot of the brake to start moving, the car shifts into park and I get a message that I need to start the car before I can move the car back into Drive. I have to keep pumping the breaks and pushing the on button multiple times before the car will restart. This is extremely dangerous, especially with our two little girls in the car. When trying to restart the car, a red battery light will show up on the screen very briefly but goes away. After the car is successfully started, there are no battery warnings. In normal situations, the car starts with no issues. We have a service appointment tomorrow to have this checked by Acura.
