UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM
This is my first luxury car. Ever since I bought the car in 2019, I noticed that sometimes when I press on the gas pedal, it takes a little time for the car to move. I just assumed it was normal. Never owned an Acura before. Two weeks ago and a week ago, I also got into a car accident. The first time was when I was entering the freeway. I see the cars on the freeway coming from my left side. They were far enough form me enter the freeway safely. I pressed the gas pedal to speed up so I could enter the freeway. I pressed on the gas pedal. Nothing happens. The car didn't respond. I pressed again and this time it moved. By the time my car moved and pick up speed, the oncoming cars were right behind my left side. I had to brake and moved to the right side to avoid an accident. The 2nd time, I was at a stop sign. I pressed the gas pedal. Again, the accelerator did not kick in. The car behind me honked at me. It took a couple of seconds for my car to pick up its speed.

POWER TRAIN, VEHICLE SPEED CONTROL
It seems that, from the day we purchased the vehicle, there have been issues with the transmission regarding how it is programmed and how it responds to drive or input through the throttle. This causes the vehicle the occasionally lurch forward under acceleration, especially at low speeds in the parking lot. And times the throttle gets really confused and the transmission fails to deliver power to the vehicle for a second. This has happened to me two or three times. I was turning left when the vehicle lost power momentarily and oncoming traffic was headed straight for me and my vehicle. If the delay had lasted just a while longer, things would have looked very bad. Based on my research online, I am not the only driver experiencing this kind of problem with the transmission.

ELECTRICAL SYSTEM
Keyless Access/TPMS Control Unit is failing. Vehicle randomly behaves where all dash lights blink on and off, head lights turn on, car alarm intermittently alarms, and motorized steering wheel moves. It is unknown if there is any malfunction to ADAS or other systems due to this random behavior. Vehicle cannot be parked with the battery connected as all of these events intermittently happen and drains the battery. The behavior is so startling and a concern to drive that it is unknown if it will completely fail and shutdown while driving. For example, the Keyless Control Unit could potentially fail to recognize the key while driving and then the vehicle would shutdown as if being stolen. Vehicle has been inspected by the dealer, confirmed malfunction and noted occurence with other customers vehicles of same make and model. Diagnostic report by dealer states the failing component.

VISIBILITY:WINDSHIELD
Acura & the service center ripped me . The issue in the car started on aroud start of septmber 2022 . They did some front glass replacement which is not under warranty . When I purchased the car from Acura it was an Acura certified car and had a 7 year warranty on it.But your service center is saying it is not under warranty . The issue caused the leak is not from any of my mistakes , I only fixed the car at the same service center which also concerns me about Acura brand reliability . The Carpet was covered under my insurance and the 30 days I didn't get a loaner car from your dealership . I need to have a big fight with your dealer to get this issue resolved and then I got one . This 30 days car I spent nearly 400$ with insurance to have a car . I agree the supply chain issue caused a 5 months delay for the carpet . I raised the concern in December that the car is ideal for the service center and has any issues .Please see the rust happen under the seat rails . This is concerning me .I am not sure how much rust is under the carpet now . I spent 1076.76 on the car for this issue but the rust in the bottom of the car concerns me a lot . Also in the bill they say it vacuumed all the interior but 3 rows was a mess with old carpet . I am not expecting this experience from a premium brand service . Added the ticket with Acura and they assure they will look with the service and nothing happened . Now my insurance went up . I am concern on the resale value of my car .

FUEL/PROPULSION SYSTEM, ENGINE, UNKNOWN OR OTHER
The vehicle has experienced an acceleration hesitation issue on a number of occasions. When I depress the accelerator from a stop and take my foot off the brake the vehicle does not respond. If I take my foot off the accelerator then depress it again all the way to the floor the vehicle after 3 or 4 seconds will lunge forward. In an intersection this "stall" may cause a collision with another vehicle. This has happened on a number of occasions but fortunately no accidents yet. I have taken the car to the dealer on no less than three times for this issue and been advised that no repair is necessary and that it was simply "a characteristics to this vehicle model and no repairs are needed."

ELECTRICAL SYSTEM
The car was bought in November, 2018, and is still under warranty. In the morning of October 3, 2022, The car would not start. The voltage of the battery was measured to be about 11.5 V. A new battery was bought and put in by myself on October 4, 2022, since I did not realize that the battery was still under warranty. Everything looked normal on October 5, 2022. But in the morning of October 6, 2022, the headlights were found to be on even though nobody was around the car parked in the garage. Sometimes the alarm would go off. This happens randomly but frequently ever since. An appointment was made with the dealer, and the car was checked out on October 10, 2022. The dealer determined that the Keyless Module Unit was faulty, but the part was on back order. The service advisor assured me that it should be safe to drive the car. Ever since, the car has been trying to start itself frequently and randomly. It would turn on the headlights, move the driver seat, go through the engine turnover cycle, etc. Sometimes it also moved the window shield wipers, or sounded the alarm even though the car was not locked. Being afraid of driving the car, I started to ask for a loaner or rental car from the the dealer on October 12, 2022, and have been talking to both Acura warranty department and the dealership since. Today (October 24, 2022) the car would not start, and had been towed to the dealership. Now it has been more than a week, I still cannot get a rental car from Acura, even though the service director from the dealership also had a concern about the safety of driving the car or leaving the car unattended.

FORWARD COLLISION AVOIDANCE: WARNINGS
2018 purchased a little more than a month ago as a certified used Acura. Twice now we have been overridden by the automatic forward collision detecting something in front when NOTHING was there. Once on the freeway went from 70mph to 15 quickly and almost got rear ended. Just now on city street car stopped in the middle of intersection while turning left and overrides driver pressing gas pedal in both cases. Makes us scared to drive suv further and we have turned off that feature to see if it still happens.

On a regular basis, if accelerating to cross an intersection, car stops or hesitates for several seconds. We have almost been hit by cars several times in the past year. Dealership states everytime i have it serviced, they are unable to replicate and they have never heard of this. In a 5 minute internet search I have found many references to the same issue.

VEHICLE SPEED CONTROL, POWER TRAIN
When trying to accelerate after braking the vehicle has a MASSIVE hesitation where it just sits there doing nothing literally for a solid second. Not only being very frustrating it's IMO very dangerous. If I'm at a yield and then need to merge quickly, if I'm getting on a highway from a parking lot, if I'm trying to switch lanes in traffic, etc etc the vehicle just bogs down and does nothing for that 1-2 seconds. Drive the vehicle normally, apply the brakes and then right away take your foot off the brake and accelerate. You don't have to mash the accelerator, even with light to moderate pressure you will notice that lag where the vehicle is just sitting there with zero power. If you do accelerate moderately or hard after a second or 2 of doing nothing it will just completely jerk into motion. Does the same thing in all modes, it's actually worse in Sport and Sport+ mode because you get more power after the hesitation After braking moderately hard from 40mph to 15mph because someone cut in front. Then I changed lanes and had to accelerate because that other lane was going quite a bit faster. Hit the gas and nothing for what seemed like the longest 1.5 seconds until the thrust came back online Pattern: From Stop --> Accelerate for about approx 20 MPH -->Release the gas pedal and immediately apply the gas pedal. Another pattern: Travel in about 40 MPH, apply the brakes to a speed below 20 MPH and apply gas pedal. Consulted with the dealer multiple times and they think this is normal for 2018 MDXes. But it is indeed a safety concern. The dealer said they applied TSB 20-015 TCM update and it still has not resolved the problem. THIS IS A HUGE SECURTY ISSUE and DANGER HAZZARD. The issue happens every day. Below reported date is the latest occurrence.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
My vehicle has similar behaviors to the most recent investigation that is happening with the investigation of the Honda Accord and CRV noted in this article: https://static.nhtsa.gov/odi/inv/2022/INOA-PE22003-5540.PDF. On a handful of times while driving on the freeway, my car has unexpectedly decelerated when passing another vehicle, or on a curve the adaptive cruise control slows the vehicle down. On one occasion, the car suddenly applied the brakes and slowed us down at least 10mph. In any of these instances, I have not had anyone following, but could have caused issues if there was.

VEHICLE SPEED CONTROL
When the car accelerator pedal is pressed, from either a stop or slowly rolling from a stop, there is no response from the vehicle, no transmission downshift, no sounds - it just sits as if the car is off for 1-3 seconds and THEN accelerates/lunges. This happens everyday, intermittently throughout depending on where we are driving and the number of stops/turns but it is repeatable. This is a safety concern when attempting to turn left when there is oncoming traffic. I have reported this to the dealership of purchase 3-4 times and have been told there is nothing wrong with the vehicle.

UNKNOWN OR OTHER
When driving at highway speeds, intermittently and unpredictably, the throttle control will become unresponsive and RPMs will drop to minimum levels. This causes the vehicle to rapidly decelerate, creating an incredibly dangerous situation. When this occurs, the gas pedal becomes unresponsive and has no control over the RPMs or speed of the vehicle. This has happened approximately 6 times and each time has resulted in trailing vehicles to have to perform evasive maneuvers to avoid hitting our car from behind. We have brought the car in to an Acura service center on 2 occasions with no resolution, even though the service advisor has stated that she has received this complaint on numerous occasions from owners of this model and year vehicle.

Car miss shifts especially in the 25 to 40 mph range. Sometimes hesitates when taking off. Also stays in one gear and will not upshift when entering the Freeway. Very dangerous. I found numerous complaints on the web in reference to these problems, but still no recall??? Have told the dealership about these problems with every service, but they said that there is nothing wrong.
