The contact owns a 2020 Acura MDX. The contact stated that while driving at various speeds, the vehicle hesitated while accelerating.

The vehicle was driven to the residence and examined by an independent mechanic, and it was determined that the PCM had malfunctioned and there was a computer miscommunication between the engine and the transmission.

I was pulling up to our house to park in the open garage as I typically do and was in the driveway with my foot lifted off the gas pedal to allow the car to coast forward slowly. The car hesitated for a moment before it lunged/accelerated on its own with such force I had to slam on my brakes to avoid the car hitting the wall of our house. I did not have cruise control on. Took the car to Acura dealership for a multi-point inspection and they found nothing out of order that would’ve caused that to occur.

I was driving on a normal sunny day when every light on my dashboard came on. I initially panicked thinking my car was going to shutoff while I was driving it. This is in conjunction with the car stalling out when the auto shutoff feature malfunctions. After researching the issue, I realized the safety camera was no longer working and a major concern. A malfunctioning front camera can prevent the vehicle from automatically braking or maintaining lanes, hence increasing the risk of collision. I am requesting that the federal safety agency investigate the front multi-purpose camera system on the 2020 Acura MDX for potential defect and safety hazard.

1. The car accelerates by intself. The accelaration is like "hiccups". When reversing and changing to D gear, it takes longer than usual for the accelarion to take effect. Yes, car is available for inspections 2. It is dangerus because it gets the hiccups even at high speeds. If it is a serious egine problem, which seems like it is, could cause an accident. 3. The car was taken to the dealership for 3 recalls but it got worse after the recalls were fixed. Supposedly the recalls were supposed to fix the issues. We have not taken it back yet. 4. There is no lights or warnings when it does it.

Hello, so far 4 to 5 times my MDX automatically shifted to Neutral gear at traffic signals. THen vehicle stops and not moves, i wouldn't be able to change the gear, the vehicle just seems stuck. COuple of times the cars behind almost crashed with my family in the car. ONly options is to power off the car and restart. I took to the dealer, they ran all the tests and nothing found in the debugging. Looking online, looks like many customers have experienced the problem with Acura vehicles [XXX] ). This is a huge safety concern as i feel we are sitting ducks for any fast moving vehicle. Can you please get Honda/Acura to rectify this problem for existing cars and not to play with customer lives INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I stopped at a stop sign and the car went into N without me changing anything. The car wouldnt go back to D or P mode even when I pressed the buttons. I had to turn off the car and turn it on again to make it function properlty. This happened twice within 5 mins.

I've experienced stop and stall issues with my vehicle three times and the Acura dealership said they couldn't locate but kept my vehicle for a few days and said it was the battery. I have a new battery but same issue occurred two more times. There is definitely an electrical problem with this vehicle's system. The radio randomly stops working, no sound or buttons stop at any given time and also heat/air buttons switch by themselves. Shift paddles sometimes does not slow down vehicle, in most cases it accelerates.
