I was stopped, my vehicle brake stopped working after being stopped on a road at a traffic light behind a semi truck. My vehicle crawled slowly forward, it would not stop (like the car wash pace). My brake would not work, I tried putting car in park to stop it moving. It proceeded to ram into the semi in front of me and keep trying to go forward until the light turned green and the semi drove away at that point I was able to drive my car and pull off the road and my brake began to work when I pulled off. It completely stopped working when I was on a busy road and caused the accident. It could have been much worse if I was not stopped already.

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)

While driving with my small children in the vehicle, my 2022 Acura MDX suddenly displayed multiple simultaneous system failures without warning and the steering wheel locked and the car slowed and the brakes didn't work well: •Brake System Problem – warning that braking performance may be reduced •Electric Power Steering Problem – “Do Not Drive” warning •Vehicle Stability Assist Problem •Hill Start Assist Problem •All Wheel Drive System Problem - •Adaptive Cruise Control Problem •Collision Mitigation Braking System Problem •Lane Keeping Assist System Problem •Trailer Stability Assist System Problem •Brake hold system problem •Vehicle Stability Assist Problem •Electric Power Steering System Problem •Low Speed Braking Control Problem •Road Departure Mitigation System Problem These failures created a serious risk to my life as well as my children's lives by simultaneously disabling braking, steering assist, stability control, and AWD traction. If this had occurred at highway speeds or in a location without space to maneuver, it could have caused a severe crash and even death. The vehicle was towed to the dealer immediately.The tow truck driver stated that he had transported another 2022 Acura MDX with identical failures earlier the same day, suggesting this may be a widespread defect. The dealer found no recalls and attributed the issue to a steering angle sensor malfunction. Given the severity and the risk of injury or death, I am reporting this to the federal safety agency. Request: the federal safety agency investigation into whether this is part of a broader safety defect affecting 2022 Acura MDX models, and whether a recall or manufacturer corrective action is warranted.

All electrical systems failed while driving around 30mph, Power steering failed, power brakes failed, lane assist failed. We were at high risk of a crash due to lack of control of the car while driving. We were lucky that it happened on a flat road and we were able to manually pull over to the side of the road. The vehicle was inspected by the manufacturer and we were told that the car did show all the steering angle sensors did malfunction and fail. They said there is no known cause. They just recalibrated and reset the sensor and said it now is ok "at this time." There is no guarantee that the problem won’t happen again and put my family’s life in danger. Prior to this incident we repeatedly got the "BRAKE SYSTEM: Brake system problem, Brake performance may be reduced, See your dealer". We took it into the deal and was told nothing is wrong with the car and this is a known issue. Dealership Service video: https://app.truvideo.com/v/CbRSGHvo?s=46jtvtJ1AFXkZdwwQ3gE7pDBzV4dlDl0

While driving on the highway (morning traffic moving at speed limit - 65-70 MPH) I smelled smoke. Immediately following this there was a thud and then the check engine, ldw and other lights illuminated on the dash, along with audible alarm sound. Smoke was now visible, coming from the engine (under the hood). I was able to move from the middle lane to the right lane/exit lane as I knew I needed to pull over immediately. Since I was in an exit lane there was no real shoulder and I started down the exit ramp. The smoke was very strong at this point. I went to depress the brakes to slow down on the exit ramp and try to pull the car over but I had no brakes. The brake pedal went right to the floor. I had limited steering control and was driving erratically trying to keep control of the car while on the exit ramp. I tried to put the transmission in park - no effect to slow the car. I tried to power the car off - did not work. I had to depress the emergency brake to stop the car. It took over 100 feet to stop the car (luckily no other cars on the exit ramp) at which point I could pull over on the side of the road. At this point there was smoke billowing out of the engine area, smoke coming in to the car. I called 911 and they responded in about 5 minutes. After I got a safe distance from the car I could see flames coming from the bottom of the engine. From there I could see the fire start to grow in the engine compartment and once the fire dept arrived it was engulfed in flames. The car has been deemed a total loss by my insurance company. This is a very concerning situation as the car had a major, catastrophic failure with essentially no warning, including complete loss of braking and significant loss of steering, followed by a fire. The car had less than 12k miles and was about one year old. No issues or service other than standard maintenance.
