upon turning right, the car lost power, degraded acceleration as if someone is holding and pulling the car to move forward. The traffic behind me expected me to cathup with the speed on the road but due to loss of power and engine hesitation i got honked and was luck to avoid a crash from behind on a busy road. Acura dealership in Dallas dont have parts since a very long time. They have pleant of new cars to sell but not repair.

Persistent Idle Start issue not being addressed by the Acura dealership despite multiple trips to the dealership with the same issue. My SUV intermittently shuts down in the middle of busy intersections leaving me at great risk for a crash and bodily harm. There is a Service Bulletin issued in January 2023 by Acura admitting to the issue and it shows how Acura will resolve the issue for affected vehicles. Unfortunately Acura is not following their own Service Bulletin, and a recall of these vehicles needs to be issued to address the affected vehicles. I am requesting the NHTSA to take immediate action and issue a recall for this known idle start issue that is putting many Acura drivers at increased risk for bodily harm.

I purchased this car in September of 2023 with 23,000 miles on it then I received a recall in December 2023. I purchased tires for my car at the dealership and they scheduled my car to have this recall to be fixed on Monday May 13, 2024. I brought the car in on Monday and received a call on Saturday May 18, 2024 to pick my car up from the dealership that it was fixed. I took my car to get gas and two lights on my dash board came up one about my emergency brakes and the other code stated that there is a engine problem and immediately bring the car to the dealership less than one hour of picking it up from a so called recall repair that I was told was going to take two weeks to fix ended up less than 5 days and the car is back at the dealership less than a hour of picking the car up today. I am pissed off and the car is a $40,000 car I paid for with these types of problems when Iam paying a $680 a month on the car note and can-??t drive it. BTWay the car smelled of burnt oil while driving it back to the dealership when the lights came on. I want my money back on this recall I need to let you know that is why I bought a new car so I wouldn-??t have to deal with this big ass migraine. The dealership needs to replace my car period in my eyes this can-??t be fixed it already has to many problems and issues with this vehicle.

- Gilbert, AZ, USA

Car stalls when auto idle at stop lights. There is a recall for my make and model however, I called Acura and they said my vin was later removed from the recall. The service bulletin states all trim levels and my MDX falls within the parameters. They could not tell me why my car had the recall once listed and then removed. This is very dangerous because it takes a few minutes for the car to start again.

The engine started knocking while driving on [XXX], it can be inspected upon request. This knocking is due to the connecting rod bearing failure recall and it creates a safety issue for passengers and other drivers on the road as the engine can fail at any given moment causing a road hazard. I have made an appointment to get this matter diagnosed with King Acura in Hoover, but I am being denied a supplemental vehicle. This is a manufacturing defect that should be completely covered by the manufacturer including supplemental transportation for the duration of diagnosis and repair.

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.

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!

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.

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.

While driving, in the middle of the high way, the car shuts off and stops and when restarted it wouldn-??t go. Stopped, twice this month and three time total this year, on the Highway thank god no accident.

Our Acura MDX has continued to have Auto Idle Stop issues since we purchased the vehicle. Sometimes the vehicle would not restart after being stopped at a traffic light. Most recently, an accident almost occurred when the vehicle stuck behind us at the traffic light tried to go around us while we were trying to get the engine started and almost collided head-on with an oncoming car. The dealership performed a software update but it did not fix the problem. Acura claims that the engine can be restarted immediately after putting the car into Park, but in our experience, it takes much more time than that.

- Bethesda, MD, USA

Periodically when accelerating the car (2020 Acura MDX) looses power. The car does not stall it just looses power. There have been times when we have had to pull over to avoid causing an accident. When it does occur there are no warning or signal displayed on the dash boards pre or post the incident. We have reported the issue to Acura but there has be no resolution to the issue.

My 2020 Acura MDX shuts down and shifts to Neutral while stopped with the auto shut off feature engaged. This happens intermittently and the only remedy is to shut the car off and restart. It only seems to occur when the auto shutoff feature is engaged.

- Blue Bell, PA, USA

The engine idle stop function is unreliable and often fails to restart the engine when the brake pedal is released. The vehicle will, suddenly and without notice, become inoperable and undrivable wherever it rests, whether at a red light or stop sign, in the middle of an intersection while making a left-hand turn, or on an entrance ramp to a highway, causing a dangerous situation for myself and other drivers. It takes several minutes to restart the engine and sometimes must be jump-started. The issue has been reported to my local dealership, and they said it is not covered.
