While making a left turn into a parking lot my car exhibited a loud bang noise. It felt as if the car had been hit from the rear. While applying the gas the car jerked and popped in the rear. I had the car towed to a dealership where I was informed the transfer case had " Destroyed itself". The gears broke apart internally. I was also informed that the transmission power take off was destroyed.The car only has 87000 miles on it and has been serviced at recommended intervals. The dealership quoted 19000.00 dollars to repair. The car was out of Acura"s powertrain warranty. I had a third party warranty that I used to repair the car. I was 5 hours away from home when this occurred. I was without a car for 4 weeks. I believe that this is a manufacture problem and is dangerous. There were no warning lights before or after the event. The car has been repaired. I have a video of the dealerships diagnosis of the transfer case and transmission failure.

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.

I have taken my vehicle to the Acura service department three times for this issue. Each time, they were unable to find a fault code or permanent fix. They have repositioned the front camera and removed an Acura sticker from the windshield, but the problem continues to occur at random. The service department said diagnostic tests show no error, yet the system still triggers false collision warnings. I’m concerned about the safety of driving a vehicle whose collision avoidance system malfunctions without warning. This issue has occurred on city streets and highways, in clear weather, at various speeds. The alerts come on suddenly with no obstruction ahead. Acura has not provided a permanent fix, and I feel unsafe driving the vehicle. I am requesting that NHTSA investigate whether this is a common defect in 2023 Acura MDX models.

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.

Transfer case became defective and fluids started mixing in with it and in the result of all of that I needed a new transmission as well

My 2023 Acura (VIN# [XXX] ) has experienced two separate incidents of sudden, total power loss while driving. In both cases, all dashboard warning lights came on, including the brake light, and the vehicle reduced speed to 20 mph and would not accelerate. The first incident occurred while I was driving on a 55 mph expressway, creating a major safety hazard. I had to maneuver to safety in high-speed traffic. The second incident occurred under similar conditions. The dealer has been unable to resolve the issue. I am filing this report to document the safety risk for investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
