SERVICE BRAKES, ELECTRICAL SYSTEM
1) I was struck by a vehicle that ran the stop sign at 50mph. After the impact my vehicle continued rolling forward and wouldn’t stop. I ended up a block away from the accident and my emergency brake, brake pedal and center console brake would not engage. My vehicle was stopped after a car pulled up infront of me for me to rear end it to stop. Vehicle is a total loss and sitting in a tow yard. 2) I was in the vehicle with my 3 children under 7 years of age. Our safety was put at risk because If the accident would’ve happened on a main street I could’ve rolled into on coming traffic. 3) Not yet, they have declared the car a total loss and have no interest in inspecting for damage repair. 4) No 5) No failures were detected nor happening prior to accident.

SERVICE BRAKES, HYDRAULIC, AIR BAGS
The contact owns a 2022 Acura MDX. The contact stated that while driving at approximately 2 MPH and depressing the brake pedal, the brakes became stuck or jammed. Later, while driving at approximately 15 MPH, the contact again depressed the brake pedal; however, the brakes failed to respond, remained stuck, and failed to stop the vehicle in an intersection, causing the contact to steer to the right and resulting in a crash with a government dump truck. The driver’s child informed the contact’s husband that the brakes were not working. No warning lights were illuminated at the time of the failure. The contact associated the failure with NHTSA Campaign Number 25V391000 (Service Brakes, Hydraulic). The driver's iPhone detected the crash and automatically contacted the emergency contact and the state police. The driver sustained injuries to the knee, head, neck, and back and was transported to the hospital for medical assistance. There was no airbag deployment, fire, or police report filed; however, a police officer and the state police were present at the scene and moved the vehicle before photos could be taken. The vehicle was towed to an impound lot and later to an auto body shop. The local dealer was contacted and confirmed there were no recalls applicable to the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 65,000.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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 NHTSA investigate the front multi-purpose camera system on the 2020 Acura MDX for potential defect and safety hazard.

POWER TRAIN, VEHICLE SPEED CONTROL
There were several instances where my vehicle either accelerated or decelerated while I was driving. I first noticed the issue about a week after I purchased the car in May 2022. I took it back to Acura of Brookfield, and they said they couldn’t replicate the issue. I also took my car to Acura of Brookfield in September 2023 for the same jerking issue. They charged me for an update, but the issue did not change. I continued noticing the problem over the years, but it happened more frequently in 2025. In May 2025, I was driving down a hill in Brookfield, Wisconsin, when my car jerked aggressively and then accelerated on its own. Throughout the rest of the year, it would either accelerate or decelerate while I was on the highway. On January 20, while I was on my way to the gym, my car jerked and decelerated while I was on the highway. I was able to pick up speed again and continue driving to the gym. When I came back out, my car started, but it would not shift out of park. I had the car towed to Acura of Brookfield, and they said something about the hydraulics inside the transmission being bad, and that they had to replace the entire transmission.

ENGINE
My 2025 Acura MDX (under 10,000 miles) has failed to restart after the automatic idle stop engaged at stoplights and drive-thru lines at least 7 separate times. When I release the brake, the engine often remains off and the vehicle will not move, leaving me stopped in traffic. I have not yet required a jump start, but on several occasions the vehicle came very close to not restarting at all. This most recently occurred at a sandwich shop drive-thru. These incidents occurred in normal drive mode and in normal weather conditions. No abnormal driving conditions were present when the failures happened. Other owners online report the same problem, with some needing to carry jumper cables. I believe this is a serious safety risk because the vehicle can stall unexpectedly in intersections and traffic when the auto stop-start system activates. I am now concerned about relying on this vehicle in traffic because I cannot trust it to restart when stopped.

POWER TRAIN
While driving in snow and in light rain noticed the MDX pulling and slipping. I realized that only the front tires were trying to drive the vehicle which was causing the car to pull sideways and slip all over the road. I made an appointment with the ACURA dealership and they found the transmission splines stripped out that drive the rear wheels. There was no warning lamps or indication that anything was broke other than very hard to drive in any kind of snow or rain. Talking with the dealer and looking online this seems to be happening to other MDX s also. My car was fixed under the manufacturer warranty and the transmission and transfer case were replaced.

ENGINE, POWER TRAIN
While driving at highway speed, the vehicle suddenly lost the ability to accelerate. Immediately prior to this, the vehicle was making an abnormal engine noise, which continued until the failure. "Drive" light turned off and the "Neutral" turned on its own. I tried to get it to shift back to "Drive" and it wouldn't. I pulled off to the side of the highway. The engine stalled and the vehicle would not restart. The vehicle was towed from the highway and we were told to have it towed to Acura dealer in the morning. This incident occurred while Recall 23V-751 (engine connecting rod bearing defect) was open and incomplete.

VISIBILITY/WIPER
The windshield washer fluid does not come out of the nozzles. On a wintry day, there was a lot of dirt and grime kicked up from other vehicles and I was unable to see out of the windshield and it caused a very dangerous situation. Acura knows this is an issue but does not want to accept responsibility. There is plenty of fluid in the reservoir and I made sure the nozzles were clear of debris. The vehicle has not been inspected by the dealership or anyone else. There are no warning lights.

STRUCTURE:BODY
This car is consistently garaged. It was pulled out one morning and a large sheet of paint peeled off roof while it was sitting in the driveway. This is a major concern as I don't feel comfortable driving the car for fear more will come off, affecting another driver on the highway. I've had to borrow a car until it can be fixed. Spoke to ACURA and this is a KNOWN issue for this color paint but they will not stand by their product. We have received no information from ACURA regarding this issue as they claim.

FUEL/PROPULSION SYSTEM
Hi, Vehicle experienced sudden loss of power and inability to accelerate while driving. Engine entered limp mode and would not rev beyond approximately 2,000 RPM. Vehicle became unsafe to operate in traffic due to lack of acceleration. Dealer diagnosed fault code P0087 (fuel rail/system pressure too low) and confirmed failure of the high-pressure fuel pump. Vehicle had hard starting, delayed throttle response, and multiple warning lights related to engine, emissions, and drivetrain systems. This appears to be a fuel system failure affecting vehicle safety. Acura previously issued fuel-system-related recall(s) for similar vehicles, and this failure occurred despite prior recall-related service. Repair cost is approximately $2,400. Failure resulted in loss of engine power and posed a safety risk, especially when attempting to merge or accelerate in traffic. Vehicle mileage is approximately 160,000 miles.
