Unable to stop the car. Luckily no accident. Brake pedal was very hard to press and car didn't stop. Brake pedal became normal again in few seconds (5- 7 sec). Inspected car. nothing was stuck under brake pedal.
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.
As slowing down to park in parking space, the automatic braking applies hard and throws you forward. All three times, the vehicle was just entering the parking space and automatically slammed on brakes causing all passengers to lunge forward and seat belt to apply hard, hurting passengers chest. This is a safety hazard as it could cause harm to the passengers and if it happens at higher speeds then could cause a rear end collision if someone is behind us when this happens. This has happened three times in the past month. We have also experienced the cruise control not working once because it though there was a car in front of us when there was not. I turned the cruise off then on and has worked properly since.
The interior breaking pad on the rear passenger side wheel is wearing faster than all other break pads. According to the dealership this is due to defective hold break caliper, a condition which they failed to identify and address this multiple times until a complete rear breaks job was required. As a result perfectly fine breaks have to be replaced because of a single fast wearing break pad. I am not sure if this condition can lead to any safety risks but right now there are significant repair costs being incurred.
LOSS OF POWER STEERING AND BRAKING ASSIST REDUCED. My spouse was driving our 2023 MDX approximately 45mph when she ran over a recessed manhole cover which created a bump. The MDX lossed power steering and brake performance reduced. The vehicle was very difficult to turn at that point. The car began to cycle through errors that would not clear until the car's engine could be stopped and restarted: HILL START ASSIST PROBLEM, TRAILER STABILITY ASSIST PROBLEM, ADAPTIVE CRUISE CONTROL PROBLEM, LANE KEEPING ASSIST PROBLEM, COLLISION MITIGATION BRAKING SYSTEM PROBLEM, ROAD DEPARTURE MITIGATION SYSTEM PROBLEM, LOW SPEED BRAKING SYSTEM PROBLEM, ELECTRICAL POWER STEERING SYSTEM PROBLEM STEERING ASSIST IS NOT AVAILABLE DO NOT DRIVE, AWD SYSTEM PROBLEM FRONT WHEELS MAY ONLY BE POWERED, BRAKE SYSTEM PROBLEM BRAKE PERFORMANCE MAY BE REDUCED. All these errors said SEE YOUR DEALER. We took the vehicle in to our local Acura dealer's service department 2 times over the course of 3 days. Both times diagnostics were ran and the car was deemed without problem. The MDX's alignment was ok as well, so the impact of the road hazard was NOT severe.
The contact owns a 2023 Acura MDX. The contact stated that while driving and depressing the accelerator pedal, the pedal unintendedly travelled down to the floorboard, causing the vehicle to unintendedly accelerate. The contact stated that the vehicle exceeded 95 MPH while driving in a 25 MPH zone. The contact stated that the vehicle failed to stop while depressing the brake pedal and drove through a red traffic light. The vehicle was taken to the local dealer, where an Acura engineer flew in to examine the vehicle. The engineer determined that the driver's side floor mat was faulty, and the floor mat was replaced; however, the failure recurred on three separate occasions and lasted approximately 40 seconds. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 4,000.
I bought the car in March 2023 and took the car for maintenance of 5k at Acura dealership at north Orlando and after that the car came never the same. The car is making so much noise skewing and clicking noise every time you turn the streering wheel. The dealership said the noise is from nuts and bolt and they did change it and noise became more loud 2nd time they said it is the front break and they did change it and the noise still the same and more of clicking noise with every tire turns . I do have a video but I could not upload it. Then for 3rd time and car been sitting at dealership for a month now they said this noise is normal and happens with all Acura MDX models. The Loaner I have is an MDX that never makes any noise . The car was running perfectly fine before the maintenance. Now noise and steering wheel 🛞 very loose and does not feel the same as before and you can hear 2 different noises in car one with breaks on and one with car or park and just Turing the steering wheels. So unbelievable that the damaged my car and I barely have mileage on it and changing all of those parts and when they came to a point that they can’t solve the issue they are saying it is a normal noise. Is it in car manual ? Why you changed all those parts to start with if that car and noise were normal? Too many questions and hidden parts for the dealership and Acura manufacture they just know half of the story and only listen to dealerships. I don’t feel safe driving the car with all of those issues and having two kids with me all the time.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
