2024 Acura MDX

The contact owns a 2024 Acura MDX. The contact stated that while the vehicle was parked, the sunroof glass shattered. No warning lights were illuminated. The vehicle remained at the residence. The vehicle was not yet diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 42,000.

2004 MDX had digital screen problems where the screen remained black upon starting, which was hazardous as I couldn’t tell how fast I was going. After 3 visits to the dealership they identified the problem and fixed it Also, in a separate instance, car stalled after trying to start up after stop signs or while waiting in traffic several times. Could have been rear ended or worse. Dealer replaced the starter at 30k miles. Still had the same issue after this and they say the car is fine.

Air suspension/vehicle height Brake systems were taken away (adaptive cruise, anti collision and lane mitigation) Yes confirmed by dealer Yes Yes warning lights

I was driving in the far right lane on the Van Wyck Expressway when suddenly my steering wheel locked up on me along with the following error messages displayed on the odometer: 1. 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.

AC / DEFROSTER / HVAC I am reporting a potential safety and health defect involving the HVAC system in my 2024 Acura MDX. When operating the air conditioning or the front windshield defroster, a strong musty odor enters the cabin. The dealer informed me that resolving the odor requires an EVAP core cleaning, replacement of the cabin filter, and the use of a disinfectant that will be circulated throughout the ventilation system to kill mold, mildew, and other contaminants. I was told this is the “first step” in addressing the issue and that the estimated cost is $440 out of pocket. This is extremely concerning because the presence of mold or bacterial contamination inside the HVAC evaporator and ventilation system affects the air my children and I breathe inside the vehicle. Mold exposure can cause respiratory irritation, allergic reactions, headaches, and other symptoms, especially in enclosed spaces. The HVAC system in this vehicle is a sealed, manufacturer-controlled system which the owner cannot access or service, so this type of contamination should not be considered routine maintenance. I have researched this issue and found that Honda/Acura vehicles have a documented history of HVAC mold and mildew odors, and Honda has previously issued internal investigative bulletins requesting dealers to collect parts from vehicles with musty HVAC smells. There are also mold-related complaints already filed with NHTSA for the 2024 MDX model year. This suggests the possibility of a broader engineering or design issue. I need this issue addressed immediately for health reasons, and I may have to initially pay out of pocket to ensure my family’s safety. However, I believe this is a safety-related defect that Acura should be responsible for correcting, not the customer, especially on a relatively new vehicle still under warranty. I am requesting that NHTSA document this case and consider evaluating whether a pattern of HVAC mold contamination exists in newer Acura vehicles.

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.

Front sunroof panel spontaneously exploded while driving on the interstate highway. No impacts or other things touched the sunroof. Vehicles behind had to avoid large portions of the sunroof panel. Flying glass made it dangerous to quickly leave the highway. This is a 2024 mdx with less than 30,000 miles. Never been in an accident before.

Heard a loud “pop” while sitting in parked car. Radio volume spiked up and the passenger side of windshield was shattered. Clear defect in installation.

When cruising or coming off a stop, my car is incapable of accelerating promptly if I am trying to get out of the way or even merge into oncoming traffic on a highway. There is a severe acceleration delay perhaps with the throttle body. I have seen online complaints but the dealership said there has to be an actual recall number to correct this. My car has been in several times to fix this. A computer reset did not work. My car is one year old.

on [XXX], I was trying to park under the shade of a tree when the vehicle suddenly surged forward, ran through the back of a big concrete dumpster retaining wall, pushed the dumpster at least 3 to 4 feet forward. It all happened so fast, I was left puzzled about why the brake failed and caused the accident and property damage. Luckily there was no personal injury to me nor anyone else, my car video showed that I narrowly missed 2 Hispanic young men standing near the dumpster ! Since the car is still under warranty, my plan was to get the car checked out by the dealership mechanic after the body shop finished with the $18,000 repair job. Then on 7/31/2025 I received a recall notice from Honda about BRAKE PEDAL PIVOT PIN may not have been staked during production. I immediately contacted State Farm and Honda. On 8/6/2025 A Honda representative, Mr. Noah, called and advised to have the car inspected by dealer for recall issue. I did not agree to it due to what I believed to be a conflict of interest : since the dealer is part of the same network with Honda ! Noah then suggested to get State Farm to request an EDR download of specific data providing insights into what happened before , during and after a collision. or I can order one myself. In accident cases involving vehicle recall, the manufacturer is considered a key party when it comes to investigation, why we consumer need to foot the bill knowing that ordering EDR is not assigned to a single party! It has been more than 3 months now since the accident, and my car is still sitting at the auto shop waiting for an EDR its data might have already been overwritten !! I have never heard from Honda again after 8/6/2025 !! They just ignored my phone calls, emails, accident video and photos totally. There were no warning lamps, message or other symptoms of the problem prior to the failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Acura MDX Sunroof Explosion striking my wife face and glass going into my kids 5 and 3 car seats. The dealer nor American Honda are not taking accountability for it.

The contact owns a 2024 Acura MDX. The contact stated while driving 55 MPH with the cruise control activated, the vehicle unintendedly decelerated to 6 MPH. The contact pulled over to the shoulder of the roadway, where the vehicle returned to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 7,000.

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 that while driving approximately 10-15 MPH and coming off an off-ramp, the vehicle suddenly stalled. The contact noticed that the instrument panel had flashed red. The contact called for AAA Roadside Assistance. The contact stated that AAA Roadside Assistance arrived on the scene and inspected the vehicle, and became aware of corrosion on the copper wire terminal connected to the battery. The vehicle was towed to the dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 9,000.

1. Brake Pedal Sinking to Floor While Stopped - While stopped at a traffic light or in stop-and-go traffic, the brake pedal intermittently sinks all the way to the floor despite steady pressure being applied. This issue occurs sporadically, making it difficult for the dealership to consistently replicate during service visits, but it has happened multiple times. Critically, once the pedal sinks, it does not return to its normal position on its own. I am forced to manually pull it back using my foot, which is both dangerous and unacceptable in a modern vehicle. This creates a serious safety hazard and raises concerns about potential failure of the braking system. 2. Delayed Brake Engagement - The brake pedal consistently travels halfway before the braking system engages and slows the vehicle. On all three occasions, I was told the problem could not be replicated. Despite their findings, the issue persists and poses a serious safety concern, especially in real-world driving conditions. This concern is even more urgent because I regularly transport my family, including my two toddlers aged [XXX] and [XXX] , and I need to be able to rely on the braking system to keep them safe. I have reached out to Acura on numerous occasions to report this issue, but so far, my concerns have not been taken seriously. I have not received any meaningful support or escalation despite clearly communicating the severity of the problem.

I was pulling into a friend’s driveway. I had my foot on the brake was barely creeping forward. Without any yellow warning, the car slammed on the brakes for me. It hit the brakes so hard, I had smoke coming out of my front, middle vents and when I got out of the car, it smelled very bad and I had smoke coming from my brakes. There was nothing in front of me. The same incident also happened to my husbands few days earlier while he was pulling into our garage.

I purchased this car in late February 2024. In late July, without any provocation or incident, the windshield cracked on the driver's side. I took the vehicle to an Acura dealer in Virginia Beach, VA, and asked about replacement. The car was less than six months old, and only had about 4,000 miles on it. The dealer stated to me, after taking a number of photographs, that they (the dealer) would submit this as a warranty claim to Acura. I was notified about two weeks later that he windshield was indeed covered by the warranty and that I could make an appointment in early September to have the windshield replaced. Since then, the appointment has been a constant postponement by the dealer and ACura stating that the part -- iu.e. a new windshield -- is not available. The last notification arrived by email this past week (and I am happy to forward the emall chain to you). I cannot het a response form either the dealer or Acura as to if and when this windshield will be replaced. It has not been six months since I started the process.

Rear storage compartment is collecting lots of moisture. This area is growing mold on the carpet and lid. Not sure if there is a faulty drain issue or the manufacturer failed to insulate this area properly causing major condensation. This is a serious health hazard concern as occupants are now exposed to mold. Vehicle is scheduled to go in to the dealership to test for water leaks 2/21/25. Until we get into the dealership, from my observation it appears to be an issue with condensation from improper insulation/engineering.

On more than several occasions the car has slammed on the breaks for no apparent reason. This has happened multiple times and thr dealer can’t fix the issue because the computer is showing no error. This is a serious concern for me as the last time it occurred a child hit her face on the back of the passenger seat causing her lip to bleed.

I was lightly stepped on the gas coming off a complete stop with no cars in front of me. The automatic breaking came on hard and a sensor flashed to BRAKE as if I was going to hit someone but there was nobody in front of me. The sensor alert system was turned off 15min prior as I had gone through a car wash. This is the first time this has happened but unknown why. Had there been a car behind me, I may have been hit.
