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.
Asymmetrical wear on the front brakes. The outer pad wears out completely while the inner pad( with the brake wear sensor) shows almost no wear. The dealer (Park Place Acura, Plano Texas) brought this to my attention on November 3, 2025 saying only the front pads needed replacing but did not disclose the asymmetrical wear. I took the vehicle back to the Dealer January 15, 2026 for repair after discovering the asymmetrical pad wear and pointed that out to them. The brakes can completely wear to the backing plate on the outer pad while showing no wear issues with the brake sensor on the inner pad. This condition creates an unpredictable and uneven braking response that constitutes a safety defect, as the brake wear indicator system fails to alert the driver to actual brake wear on the outer pad. The brake wear sensor is designed assuming symmetrical pad wear. When wear is asymmetrical, the sensor fails to trigger a warning, leaving the driver unaware of a dangerous condition. The dealer has finally replaced the pads and rotors, symptoms of the problem but, has not addressed the underlying cause of the problem...the calipers. I have received the vehicle back from the dealer but did not sign a release and the issue remains open. The vehicle currently has approximately 29,400 miles. I have taken this issue to Acura corporate(Honda Motor Company) and they have it under review but keep delaying with no confirmed resolution. I sent a certified letter to American Honda Motor Company, Acura client relations on February 3, 2026 and they signed for it on February 11, 2026 and contacted me by email on March 11,2026. Acura took 28 days to respond to my certified letter and has provided no resolution timeline since.The vehicle was under the original manufacturers warranty at the time of this issue and notification.
Brake system warning light comes on and says reduced braking take to dealer. Auto hold brakes don't always hold. Rear brakes non stop squeal and grab un predictably. I am unsure when and if the brakes will work in the rear. The loud noise from the rear squeal has caused others in traffic to flag me down and warn me something is wrong. The noise is also made it impossible to have my Autistic nephew in the vehicle with me as it triggers episodes and scares him. I have asked the dealer to please repair the rear brakes several times. They refused and instead replaced the front brakes, then admitted it is the rear brakes but refused to repair them. Honda of America also refuses to repair rear brakes. Based upon false statements on the work order the statement from the dealer is the rear brakes on the MDX are supposed to be like this. This vehicle has issues with the warning light while stopped and moving, and the noise and unsafe braking is at all speeding from 1-60 mph. Forward and reverse is malfunctions. I asked Honda America to repair which they won't then I ask them is the official statement these brakes are okay and safe as is and they will not say that either. I have driven similar models of this vehicle and it does not do the same thing, no noise, or warning lights, and the brakes preform safely and consistently. Mine do not. Honda of America does not want to repair the brakes under the warranty. They also incorrectly stated on repair statement that humidity and car washes can make the brakes do this. I have been in northern non humid states during winter and never use a car wash. They just use this as an attempt to not repair the brakes.
Vehicle has had 3 instances of a feeling of locking/ seizing and shutter or hesitation during braking at 40 to 65 MPH. Service light appear about brake system which quickly vanishes in less than few seconds same as feeling of the brake seizing also disappears within few seconds. This occurred from initial purchase to date at 21k miles. Vehicle brake system inspected at this service junction 2 years after purchase and at this service at 21k one single brake pad and rotor has worn on right front brake pad to 3mm. Front right Brake rotor also deemed damaged and require changing. Other 3 brakes pads and rotors meaning left front brake pad and rotor and 2 rear brake pads and rotors are in good condition at 8mm. The dealership has issued a finding from their independent warranty inspection people who refute that the brake caliper as deemed as cause of this issue in past cases have now instructed the dealerships to NOT change caliper but just change the brake and rotor affected and to do this at the vehicle owner's expense nonetheless. So the vehicle has has other identified issues with uneven brake wear of the model 2022 MDX Type S. The manufacturer is not acting in good faith to provide safe and reasonable means of addressing this issue. This issue is clearly happening to this particular MDX and now Acura does not want to find the problem and correct it. My brake has worn to 3mm and yet it is not considered a "defective" part that must be at fault? There needs to be an identification of what can be causing this as brakes are one of the major safety components for a vehicle. Acura needs to find out the cause and stop passing the responsibility of correcting an obvious defect onto the consumer with a bandaid. Changing the rotor and brake pad is not the way. The root defect needs to be addressed especially since there is obviously multiple people with same issue with this make and model 2022.

I brought my car in for regular maintenance as well as sunroof not opening plus I noticed on and off when I start the car my steering wheel vibrates, only when starting the car. Following day I received a phone call that the motor needed to be changed for the sunroof and they also need to change my brakes (car has ~8K miles on it)… and not just brake pads, rotors as well. My front passenger side brakes were basically none existent, no idea for how long and I was told it’s a manufacturers defect which was covered by warranty. I have a 4 year old and currently 5 months pregnant, needless to say I feel extremely unsafe now driving my not so cheap car.
