On April 17 2026 while driving my 2022 Acura MDX at very low speed in a parking lot, the vehicle suddenly accelerated forward without warning and surged into bushes before I could stop it. I did not mistake the gas for the brake pedal. This felt like a sudden unintended acceleration event. I was preparing to park in a stall and the vehicle lunged forward unexpectedly. I applied the brake, but the braking did not immediately stop the forward surge. Earlier, I experienced another unusual event in which the vehicle abruptly auto-braked, jerked, and made a warning sound while I was slowing for a red light. I noticed the car felt as if it was surging a bit on residential streets and was about to mention it during the next service. This incident has caused me to lose confidence in the safety of the vehicle. I contacted Niello Acura who has been very cooperative. I was told the issue would need to be duplicated or that they could only inspect it if a code had been stored once the car is repaired. The car is currently being repaired with close to 7,000 in front end damage. I am reporting this because a sudden unintended acceleration presents a serious safety risk and could easily have caused a more severe crash or injury. I did research on this issue and have found various reports of unintended accelerations in the Acura MDX forums from various years but was unable to find any recalls or outcomes with these reports My concern is this will be dismissed as "operator error" or a phantom incident that cannot be reproduced.

I was driving to work yesterday morning- busiest time of day on probably the busiest road in our area. My car started freaking out randomly. It popped up numerous errors. The steering wheel locked up. The brakes weren’t working well. I had a car behind me. THANKFULLY they were paying attention because they were very close to rear ending me. But they dodged me. I finally jerked the wheel and got it pulled over to the side of the road until someone could come get me and take me to work. There could have been a different outcome. After being hit head on in February of this year, this incident was NOT good for my PTSD!!!! My anxiety has been through the roof since this incident with a car that I bought SIX MONTHS AGO! As soon as I can trade this car off and get something else, I will be. We still don’t know what it’s wrong with it. We are going to have it towed somewhere on Monday. This was a major safety risk for me AND for the others on the road!!! If my kids had been in the car, I would’ve been even more upset over the situation.

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.

I have experienced several incidents where I am driving on open road with no obstructions in front of my vehicle and the collision braking feature suddenly engages. This has led to vehicles behind me almost rear ending my car due to the unexpected, strong, and abrupt nature of the braking on open road.

On [XXX] I headed out for an event. I had been driving for 8 minutes when I lost the ability to steer, the Brake, TSA, and Steering system warning lights flashed on the dashboard and I immediately turned onto a side street. One message stated to contact dealership immediately, DO NOT DRIVE. The car was towed to Mungenast St Louis Acura. It was scheduled for service on Monday, June 23, already, so this was perfect. It was determined the battery failed. My concern is that prior to this event the vehicle's warning system gave no indication the battery needed attention, was low in power, or anything else related to the battery. I was on a busy street however, this event could have been very much different had I decided to take the highway to my event.

the last 3 times we had very insignificant snow accumulation, my vehicle dashboard lit up with 6 different warnings, some audible. when you look up the info on them it says the car cannot steer, break, will roll on a hill etc. One warning advises to remove all flammables from the car. I was very nervous and almost towed the car but since I was a mile from home I drove it and brought it to the dealer at 0730 next day. they said nothing was wrong. snow or dirt probably got behind sensor. It has happened two more times in the next 10 days. I keep taking off work and nothing is wrong. The issue is when this happens you cannot change the vehicle to snow mode to drive. this is a safety feature as well as the flashing "brake" warning and audible alarm. I have a [XXX] and [XXX] driver and they do not want to operate this vehicle. Both times it happened again, I took it to the car wash and cleaned every visible camera and sensor to no avail. I am taking it back to the dealer again this Friday but if nothing is wrong with any of these systems then there is something wrong with the cameras because how can someone operate AWD and snow mode when there are these false warnings and how do you know if they aren't false. I don't want to assume each time it's not but 3 times in 10 days and missing work, etc. Plus I am very nervous driving it like this. I reported it to Acura- they said there were no recalls. would not provide info if they have prior complaints. On google, I have found numerous complaints about this.

While driving the vehicle and while it was in motion, I received a wave of faults. The power steering, lane departure, brake system, brake hold system, vehicle stability assist, hill start assist, trailer stability, and adaptive cruise control all failed. Consequently, the steering wheel locked completely while the car was in motion. I couldn’t steer at all, and the car was in motion! I informed American Honda and the dealer, who informed me that “they had never heard of such a problem”, and that they were “unable to duplicate the issue” when the tow truck brought it into the shop.
