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.
I was maneuvering to park my car in a parking lot. Driving down the traffic lane of the parking lot, I slowed, braked and turned left 90 degrees into the parking space with my foot still on the brake. I reached the end of the parking space and prepared to shut the engine down. I remember looking at the shift console to find the park button when the car bolted forward. The car went over the concrete curb, clipping a tree and through bushes beyond the parking space. The car proceeded down the embankment of a dry retention basin, across rip rap stone of the basin then up the other bank to the next parking lot. I was pushing hard on the brake petal the entire time with no results. The car just kept moving forward. I’m now thinking “How am I going to stop this car before it enters the busy street ahead?”. Once in this second parking lot, with a bit of mental clarity, I purposely slid my foot across the brake petal a very little bit, right to left, confirming to myself that I had not been on the accelerator. I did not lift my foot off the pedal to reposition my foot. Somehow, I was able to stop the car, or the car stopped itself in this parking lot. I was lucky that nobody else was involved or injured and there was no additional property damage beyond my vehicle. At this time, I’m not sure I will be able to trust this car again. Have there been other incidences of this ‘Sudden Unintended Acceleration’ happening to other Acura owners? Can I expect this to happen again to me?
Was exiting I275 onto Westbound Route 32 when the brakes were unexpectedly applied by the vehicle’s safety system. No vehicles were in front or beside me. Very alarming when it happened. This also happed two other times at slower speeds.
2023 ACURA MDX TYPE S. 28k miles. While merging onto highway, I sped up and at 25 mph, I heard a loud metal clunk from underneath the car. Car still drove and functioned as a two wheel drive instead of AWD. Went in for service and was told that the transmission and Power train Unit would need to be replaced and will be replaced under powertrain warranty by Acura.
Was driving arround corner and felt a shudder like I had run over something, the felt front tires loosing traction and car jerked into next lane. Took to dealer and they diagnosed a failure of output shaft from transmission to awd transfer case, currently at dealer getting transmission awd assembly replaced.
My 2023 MDX Type S is currently at Mungenast St Louis Acura. Transfer Case and Transmission are both being replaced at roughly 56,000 miles. I made a turn and heard a loud noise. Because I was under acceleration my car was hard to control when it happened. Scared me and immediately let off the gas.
The contact owns a 2023 Acura MDX. The contact stated that while driving at various speeds over a bumpy road surface or a pothole, there was an abnormal metallic sound coming from underneath the passenger’s side of the vehicle. No warning light was illuminated. The vehicle was taken to the dealer, where a technician informed the contact that the sound was common after 50,000 miles. The contact was later informed that the cause of the failure was undetermined. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but the assigned case manager failed to help. The failure mileage was approximately 50,000.
2023 Acura MDX Sport looses AWD randomly and vehicle becomes only FWD. This has happened many times now and I have taken it to the dealership but they claim they can’t recreate it and would not do anything further unless I change rear end fluid.. I paid for the service but still have the problem. This is getting dangerous as it is unexpected and alters the expected performance of the vehicle in critical turning situations which has led to two close calls of a broad side accident when turning and loosing AWD. There appears to be many more reports of this exact issue, I’m officially adding my name to the list.
While driving my 2023 Acura MDX at approximately 40 mph in rainy conditions, the vehicle experienced a sudden catastrophic failure without any prior warning lights or dashboard messages. The vehicle abruptly decelerated and felt as though the drivetrain or wheels were binding / locking. The vehicle lost the ability to accelerate normally and became effectively inoperable in traffic. After stopping, the vehicle resisted rolling freely even when shifted into neutral and required towing to the dealership. The dealership has since informed me that the front transfer case / transfer box experienced a catastrophic internal failure. Root cause and failure sequence are still being diagnosed by the dealer. The sudden nature of the failure, lack of warning indicators, and apparent driveline lockup behavior created a significant safety hazard and increased risk of crash, particularly given the wet road conditions and speed at the time of the incident. There were several near misses with other cars putting me and my family at significant risk. The vehicle is currently at the dealership pending full diagnosis and repair.
What component or system failed or malfunctioned, and is it available for inspection upon request? Transfer case and yes, it is attached the vehicle. How was your safety or the safety of others put at risk? At this time there is a leak and the power is being redistributed which could lead to loss of power at any times. Has the problem been reproduced or confirmed by a dealer or independent service center? Yea both. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Manufacturer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. During a routine transmission service this was noticed that there was a leak, they did not fill the fluid in the vehicle up to monitor fluid levels.
The contact owns a 2023 Acura MDX. The contact stated that while driving approximately 5 MPH, the vehicle unexpectedly accelerated. There was no warning light illuminated. The contact stated that the failure had occurred on several occasions. The vehicle was taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 71,000.
A little over one year after purchase, I began receiving dashboard warnings related to the air suspension and braking systems. I scheduled service with the selling dealer (located over two hours from my home). By the time of my appointment, the rear of the vehicle was visibly unstable and bouncing during operation. Upon arrival at the dealership, while the technician was driving the vehicle into the service bay, the rear air suspension bag exploded. Once the vehicle was raised on the lift, the opposite rear suspension bag also exploded. I was informed by dealership personnel that had this occurred while I was driving – regardless of speed – it could likely have resulted in a crash. The stated cause of failure was severely corroded rear stroke sensors. Including that incident, I have had a total of 5 corroded stroke sensors replaced within an approximately one-year time frame. This appears to be a recurring and systemic defect rather than isolated component failure. The repeated corrosion of critical suspension components in a nearly new vehicle raises serious concerns about moisture intrusion, improper sealing, or design defect affecting safety-critical systems. This issue creates a significant risk of sudden suspension failure, loss of vehicle control, and potential crash. I am concerned that other owners may experience similar dangerous failures without warning.The vehicle has been serviced only at an authorized Acura dealership, and all repairs are documented. Exact dates of each repair: 4/10/25 – Both rear stroke sensors (mileage: 13,632), 9/24/25 – Left rear, 2/6/26 – Right front, 3/20/26 – Left rear, Current mileage: 25,160
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.
Transfercase fluid eaking observed at 38000 +- miles, this could lead to a binded transfercase thus damage transmission permanently
The transmission of this model car is very poorly programmed a low speeds. it is constantly jerking in and out of gears making it difficult to moderate speed. There is also a substantial delay between hitting the pedal and accelerating the vehicle. The issues with the transmission paired with the very delayed accelleration leads to very ineffective control of the vehicles speed, leading to what I believe is dangerous driving scenarios. Turning through inersections, braking at a light, accellerating out of the way of traffic, are all made much more difficult/unpredictible due to how unpredictible and inconsitent the transmission behaves. It feels impossible to 'learn' how it behaves. Here is a forumn of other users confirming similar issues: https://www.mdxers.org/threads/jerky-transmission.181658/ I believe this should be addressed via software update or recall as it i'm sure will lead to accidents/injuries.
