Our infotainment system stopped working and when we took it one of Acura’s authorized dealers they told us that back half of the car is flooded and that has shot down all the electronics including the infotainment system. They also gave me a bill of $10K USD to fix the leak and replaced damaged electronics. Their argument is that the car was parked outside and that caused this issue. This has never come up in any of our previous maintenance visits where Acura certified dealerships always check our car and tell us that everything is okay.

Collision mitigation braking system problem. See your dealer 2. Road Departure mitigation problem. See your Dealer 3. Low Speed braking control problem. See your Dealer. 4. Electric Power Steering problem. Steering assist not available. Do not drive. 5. All wheel drive system problem. Only front wheels may be powered. See your Dealer. 6. Brake system problem. Brake performance may be reduced. See your dealer. 7. Brake hold problem. Apply brake when stopped. See your dealer. 8. Vehicle stability assist system problem. Reduced traction and handling. See your dealer. 9. Hill start assist problem. Vehicle may roll upon brake release. See your dealer. Thankfully I was approaching an exit ramp and I was able to steer my MDX safely off the expressway. I parked my car on the service road, turned my hazards on and then turned the car off. When I restarted the car the error messages were gone and power steering worked as if nothing happened. Acura will be hearing from me I could’ve been in a serious accident.

The start/stop switch stalls the vehicle and will not restart after several tries for up to 5 minutes. We get a message during this time to "continue to drive, depress brake pedal and push switch" and even after then it still will not start for several tries. This has happened several times. One time my wife was on a heavily traveled two lane farm road at a four-way stop and it did it and was almost hit by 18 wheelers trying to navigate around her. This was not only a safety issue for her but also those trying to get around her with all the traffic coming in all direction. Took back to the dealer but it did not do it while they tried to recreate the issue. No warnings prior to the issue of dying and not re-starting. This was the latest occurrence, it had happened a couple of times before.

Vehicle will suddenly shut the engine off and shift into park, even when the auto engine shut off is not active. Typically happens when stopped at a stop light. You will feel the engine shut off, and the car shift into park. It is very scary and unsafe. It has also caused the vehicle to shut off and shift into neutral while it was moving, and the vehicle gave a transmission warning. It sounds very similar to NHTSA Recall 25v-031, however, my vehicle was not included in the recall as it is not a Type S. I took it to the dealership and they said that Acura has opened an investigation due to the number of complaints, but there is no solution yet. I have not other option but to dry the vehicle, but I am worried that it is unsafe and not good for the vehicle to keep stalling the way it is.

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 vehicle was taken to a second dealer, Kearny Mesa Acura (5202 Kearny Mesa Rd, San Diego, CA 92111); to be diagnosed, but the cause of the failure could not be determined. 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. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failures and a case was filed. The failure mileage was approximately 9,747.

I have attached all my service records from Honda/Acura and the dealership Motorworld which is located in Wilkes Barre, PA I had my first issue with the car in January 2024 with sensors malfunctioning. They we replaced a few times, repeated issue I had other issues that didn't replicate themself or show as an error code when I brought the car in. Issue accelerating or inability to accelerate on the highway in a middle lane w/ a tractor trailer on each side. One trying to merge into my lane. Noisy brakes, low breaks etc Fast forward to March 2025, my number one complaint about these sensor issues is they would malfunction on me one day when I was driving. And I was always assured by the dealership it was good, the car was good, I was good. Acura felt the same. Well in April my steering malfunctioned while driving, the steering wheel locked as I was breaking for a red light, and I drifted off the road. Turns out my steering rack needed to replaced. It was fixed on 4/4 then on [XXX] with my children in the car, it did the same thing. Now they tell me it is the EPS, electric power steering. This car spends more time on [XXX] and one day this is going to happen on the interstate and there will be fatalities. I have been screaming at Acura and the Motorworld for months. Acura will not respond to emails (which I have kept) and every time I call the case manager assigned to me is not available. The few times months ago I did speak to someone they tell me the same things the automated email I get once in while that say my case is under review. All dates of occurrence and repair are in the service records I attached. They still have my car today, 5/8/25 so I do not have those to attach.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
