FUEL/PROPULSION SYSTEM
“fuel door stuck,” “no manual override,” “can’t refuel.” As per Acura manual there is way to open a gas/fuel door/cap/lid when actual way of opening through electronically fails due actuators or some other reasons. There is a manual release pull cable behind a removable access panel in the driver’s side of the cargo area trim, near or behind the wheel well lining. manual fuel door release is inside the trunk (cargo area) in case the electronic fuel door release fails.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I have experienced several incidents where I am driving on open road with no obstructions in front of my vehicle and the collision braking feature suddenly engages. This has led to vehicles behind me almost rear ending my car due to the unexpected, strong, and abrupt nature of the braking on open road.

ENGINE, ELECTRICAL SYSTEM
I was driving my car on the interstate and momentarily stopped due to traffic congestion. My engine idle stop feature was on and engaged as expected for the short stop, but the vehicle then stalled when I attempted to drive. There seemed to be an electrical issue with various lights coming on the dash to indicate a problem. I could not get the car to restart and was stuck in the left lane with cars then going around my stalled vehicle. I called 911 for help after I could not restart the car after 3 attempts. After approximately 5 minutes, I pressed the ignition button again, and this time my car was able to restart and drive normally so that I could exit the highway.

VEHICLE SPEED CONTROL
My 2018 Acura MDX experiences a persistent and unsafe delay in acceleration from a complete stop. When pressing the gas pedal, there is often a hesitation of approximately one second before the vehicle responds. This throttle lag creates a serious safety concern, especially when attempting to merge into traffic, turn across intersections, or respond quickly in emergency situations. The dealership has been unable to resolve the issue despite applying all available software updates. Based on online reports, this appears to be a widespread issue affecting multiple model years and drivetrains.

ELECTRICAL SYSTEM, POWER TRAIN, FORWARD COLLISION AVOIDANCE
The contact owns a 2024 Acura MDX. The contact stated the messages "Parking Sensor Failure - See Dealer", "Brake Performance Failure" and "Brakes May Be Reduced - See Dealer" were displayed. Additionally, the Forward Collision Avoidance sensor would alert the contact of a potential collision erroneously. The vehicle was taken to the dealer, where the computer systems were reset, and the front bumper sensor was replaced. The contact stated that after the repair, the auto brake hold feature failed to engage upon coming to a stop and releasing the brake pedal, causing the vehicle to roll.

The contact also noticed that the wheels were out of alignment. Additionally, the contact stated while driving at various speeds, the vehicle surged forward and felt like the transmission had shifted from 1st to 3rd gear instantly, and the failure recurred while decelerating to come to a stop. The contact stated while driving approximately 5 MPH in a parking lot, the vehicle suddenly felt like the transmission was in 3rd gear. The contact immediately depressed the brake pedal and stopped the vehicle. The vehicle was taken to a third dealer, Acura of Escondido (1502 Auto Park Way N, Escondido, CA 92029) to be diagnosed, but the cause of the failure could not be determined.

ENGINE
Catastrophic engine failure occurred while driving on July 4, 2025, resulting in the car briefly stopping at 60mph skidding tires on I-70 (a major highway in colorado), then tires unlocked and now engine moving again but with a check engine light, and acceleration was sluggish. It freaked out the family and we pulled over at the next exit to find the engine was knocking like crazy. No injuries occurred, but the sudden engine failure while driving created a serious safety hazard. Complete loss of power could have resulted in accident if this had occurred in traffic, on highway, or during emergency maneuver. We later found out engine the rod bearing failed on cylinder 4 and shattered in several pieces. We took it to both independent auto repair shop, then the dealer, both confirmed rod bearing problem, and engine replacement now required. Dealer is quoting us $24000. Failure was due to connecting rod bearing failure - a known defect currently under NHTSA Investigation RQ24-013. This failure is consistent with NHTSA Investigation RQ24-013 covering connecting rod bearing failures in 1.4 million Honda/Acura vehicles including 2016 MDX. The failure appears related to unaddressed ATF warmer defect covered under Acura's KG9 warranty extension (Service Bulletin 17-026) that compromised cooling system in December 2024, leading to thermal stress and bearing failure. Acura was aware this defect was serious enough to warrant 10-year unlimited mileage warranty coverage but failed to honor it. We had the car serviced June 25th 2025 at the dealer just 9 days prior to the July 4th 2025 incident for its regular maintenance oil change, brake fluid flush, and valve adjustment.

FUEL/PROPULSION SYSTEM
My vehicle is showing identical symptoms to those described in recall 21V-215/23V-858 related to the fuel pump. Although my VIN is not listed in the recall, I would like to verify whether my fuel pump is part of the defective batch, as it is failing in the same way (e.g., loss of power, engine shutting off, hard starting when cold, etc.). Or please confirm if my car symptoms are related to different campaigns.

The geniuses at Acura / Honda quit installing SiriusXM in the 2025 MDX and instead relies on the user's cell phone paired to the "radio" to get SiriusXM. My issue is that it cuts out when my cell phone doesn't have a clear view of the SiriusXM satellite. Sometimes it continues when reception improves, but most times I have to reboot the SIrusXM app on my cell phone. This quite dangerous in traffic and definitely is not a safe action. I'm quite ready to change cars because I don't want someone to get hurt because of this design flaw. This has been happening since I bought the car in January but is getting more frequent with the foliage on the trees.

I have experienced the vehicle not unlocking when the key fob is near(in my pocket) the vehicle and my hand is touching the door handles. The vehicle is designed to unlock when the key fob is in close proximity while hands are on the handle. This is a safety/security concern because in an emergency, the vehicle does not function as it is intended to.

Acura Headquarters USA 1919 Torrence Boulevard Torrence, California 90501 Mr. [XXX] [XXX] [XXX] Email: [XXX] Dear Sir or Madam, I am writing your company to the attention of whomever oversees the product development and design of the 2022 ACURA MDX and to warn them that certain system features and design flaws of this make and model vehicle will undoubtedly lead to the death of someone in the near future as was nearly the case with myself and spouse very recently. On Sunday [XXX], my spouse and I attended church services that morning. Fortunately, after services our Acura MDX did start as usual, and we began our journey home.Upom arriving home, we backed our car into our garage and during that process thankfully I had the wits to unlock the passenger and driver side door mechanisms. Once we enteredthe garage and at thta point, our car went absolutely DEAD. Our car stayed dead for the next 5 1/2 hours. Had I not unlocked those doors, we would have been trapped inside for that duration of time, only to be found dead fron suffocation and asphysxiation from being in a car with all the windows rolled up, no power to the vehicle and no way to get out, while beingdeprived of oxygen. AT that point, your manufactured vehicle became a death trap for us.We're the fortunate ones who lived through the experience and to be able to tell the story. Others may not be so lucky to tell theirs and there will be others. We wanted the manufacturer to understand the full implications of our letter and to stress in the strongest terms possible that this is a very serious matter that will eventually cost lives, as it nearly cost us ours. The vehicle in question is VIN# [XXX] and was last serviced at Vandergriff Acura in Arlington, Texas on 6/13/2025 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Hi, I have a 2017 Acura MDX. My Transmission Shifts to Neutral Unexpectedly. It happens when I'm driving. Most of the time it shifts back to Drive. Therefore, it never bothered me, it happened since I bough the car. It didn't happen often so I didn't think anything of it. However, lately it started to happen more often. Now when it shifts to Neutral it doesn't want to shift back do Drive. My concern happened when I was on a highway driving in a middle lane. I had to pull over and when it shifts to Neutral. When it shifts to Neutral you can't add gas and the vehicle starts slowing down. I received warning on my dashboard ((P))! - Electric Parking Brake Problem and (transition picture)- Emission System Problem came on. I turned the car off and then on. After, I turned on and Press D or R the car doesn't want to go forward or reverse. I have to turn the car off for about 15 min and then when I turn the car on and press Drive it drives without a problem. Recently, it started to happen more often. I happened to me today. I was on 2 line road on a left lane. My car stated to slow down. I was lucky nobody was on right lane, so I was able to change lanes and then I had to pull over and turn the car off. I waited 5 min turned the car on and it drove. I'm scared that I might not be as lucky as I was and get in an accident when the transmission shifts to neutral. My VIN is not on recall but there is a recall on 2016-2020 Acura MDX with same problem. 16V640/KC2 recall. I already contacted my dealer with no luck. They told me to contact Acura. I made a case # [XXX] with Acura. I was told they can't do anything and the bounce the ball again this time to NHTSA. Here I'm looking for help. My dealer found a Par 573 Safety Recall Report on NHTSA site. I love the car. I was hoping you can help me with this problem or maybe you can tell me who can help me. Thank You, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM
The car alarm started going off randomly after the car was locked and armed. This would happen periodically. The car was locked using the indoor lock and then left unlocked and the lights would go off and on periodically. The internal dash periodically would flicker off and on (dash lights/screens). The car eventually drained the battery one night cycling down to 4.25v and had to be replaced (it was too damaged to be jumped). Upon replacing the battery codes were read, cleared and the car driven. The alarm and light issue came back, and the hood latch was disconnected. This stopped the alarm, but after rain events or humid days the lights would still come on (as if someone unlocked the car or walked up with the key) and the dash lights would occasionally flicker. The wireless control unit was removed and inspected and dendritic growth was noticed on one location of the board. This was cleaned with alcohol and this has appeared to solve the issue so far. The part of the board with the growth is not sealed and looks like it is right on the edge of the factory sealing.
