UNKNOWN OR OTHER
When I was at a stop light, the car shut off and went into park. I believe the Idle Stop was off at the time. When I tried to shift to drive it told me I needed to start the car by holding the brake and the button. It took a couple of attempts for it to cycle through and start. This happened several weeks prior to the incident yesterday. It is currently at the dealership. When I googled the issues it said it was a "known issue". It could be dangerous if it shuts off on railroad tracks or in traffic.

POWER TRAIN
During a winter freeze event, the vehicle was unable to climb a slight incline despite being equipped with all-wheel drive. The rear wheels did not appear to be receiving power, and the vehicle experienced significant wheel slip under light throttle input. This occurred in normal driving conditions and was unexpected given the vehicle’s AWD system. There were no warning lights, diagnostic messages, or fault indicators displayed on the instrument cluster at the time of the incident. The lack of any driver notification made it difficult to identify that the AWD system was not functioning properly. After experiencing the issue, the vehicle was taken to an authorized dealership for inspection. The initial assessment did not identify a problem. However, after further review and comparison with a properly functioning vehicle, the dealership confirmed a failure within the SH-AWD system. The affected components were replaced under warranty. The failed components should be available for inspection upon request. The safety concern stems from the absence of warning indicators combined with the loss of intended AWD functionality. In low-traction conditions, the inability of the system to properly distribute power can increase the risk of loss of control, reduced acceleration capability, or inability to safely merge or climb inclines. No prior warning lamps or alerts were presented before the incident.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

SERVICE BRAKES, HYDRAULIC, AIR BAGS
The contact owns a 2022 Acura MDX. The contact stated that while driving at approximately 2 MPH and depressing the brake pedal, the brakes became stuck or jammed. Later, while driving at approximately 15 MPH, the contact again depressed the brake pedal; however, the brakes failed to respond, remained stuck, and failed to stop the vehicle in an intersection, causing the contact to steer to the right and resulting in a crash with a government dump truck. The driver’s child informed the contact’s husband that the brakes were not working. No warning lights were illuminated at the time of the failure. The contact associated the failure with NHTSA Campaign Number 25V391000 (Service Brakes, Hydraulic). The driver's iPhone detected the crash and automatically contacted the emergency contact and the state police. The driver sustained injuries to the knee, head, neck, and back and was transported to the hospital for medical assistance. There was no airbag deployment, fire, or police report filed; however, a police officer and the state police were present at the scene and moved the vehicle before photos could be taken. The vehicle was towed to an impound lot and later to an auto body shop. The local dealer was contacted and confirmed there were no recalls applicable to the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 65,000.

ENGINE
My 2025 Acura MDX (under 10,000 miles) has failed to restart after the automatic idle stop engaged at stoplights and drive-thru lines at least 7 separate times. When I release the brake, the engine often remains off and the vehicle will not move, leaving me stopped in traffic. I have not yet required a jump start, but on several occasions the vehicle came very close to not restarting at all. This most recently occurred at a sandwich shop drive-thru. These incidents occurred in normal drive mode and in normal weather conditions. No abnormal driving conditions were present when the failures happened. Other owners online report the same problem, with some needing to carry jumper cables. I believe this is a serious safety risk because the vehicle can stall unexpectedly in intersections and traffic when the auto stop-start system activates. I am now concerned about relying on this vehicle in traffic because I cannot trust it to restart when stopped.

POWER TRAIN
While driving in snow and in light rain noticed the MDX pulling and slipping. I realized that only the front tires were trying to drive the vehicle which was causing the car to pull sideways and slip all over the road. I made an appointment with the ACURA dealership and they found the transmission splines stripped out that drive the rear wheels. There was no warning lamps or indication that anything was broke other than very hard to drive in any kind of snow or rain. Talking with the dealer and looking online this seems to be happening to other MDX s also. My car was fixed under the manufacturer warranty and the transmission and transfer case were replaced.

Auto Idle Stop/Auto Start-Stop Issue- On multiple occasions, occurring randomly, the vehicle will not start at stoplights after auto-idle stop is engaged. Sometimes this happens after the vehicle has been running for over an hour. Currently, the vehicle must be completely powered down and then restarted to revive engine.

POWER TRAIN
While driving a 2022 Acura MDX Advance AWD in snowy conditions, I noticed reduced traction and abnormal drivability. Dealer inspection confirmed a catastrophic failure: the front differential and transmission splines were stripped, causing the vehicle to operate in front-wheel drive only. The dealer verified the failure and documented it as a defect on the repair order. The vehicle was maintained exclusively at the dealership since new, and failure occurred at approximately 76,000 miles, outside the original powertrain warranty. There were no warning lights prior to the failure, but loss of AWD in snowy conditions created a significant safety risk.This is a safety-relevant defect affecting traction and stability in adverse conditions.

The battery drains quickly. Have replaced the battery twice since 2022. something in the car is draining the battery and making it fail. infotainment screen sometimes stays grey and doesn't go black when car is off. many 2022 mdx owners are having similar battery drain issues requiring frequent battery replacements. please push Acura for a recall and fix.

POWER TRAIN
My Acura service department notified me at my last oil change that they discovered (accidentally) my transmission / transfer case is damaged and is not transferring power to the rear wheels, rendering the vehicle as 2 wheel drive only. This requires a total replacement costing $16,000 +/-. My research indicates this is likely caused by a faulty splined shaft inside the transmission-transfer case assembly used in the early 2022 MDX vehicles.The dashboard info system for SH-AWD indicates that the car IS in All Wheel Drive and there are no messages indicating a problem with the All Wheel Drive. This has not been a problem during non-snow or other slippery conditions, but recent storms have made this a major safety problem for me. The fact that the car sensing system does not detect this problem could cause serious driving danger for unsuspecting drivers. This also prevents Acura/Honda from acting on this issue publicly as owners of this vehicle have no way of knowing the problem exists until it is too late.

VEHICLE SPEED CONTROL
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.

STEERING, SERVICE BRAKES, ELECTRICAL SYSTEM
I was driving in the far right lane on the Van Wyck Expressway when suddenly my steering wheel locked up on me along with the following error messages displayed on the odometer: 1. Collision mitigation braking system problem. See your dealer 2. Road Departure mitigation problem. See your Dealer 3. Low Speed braking control problem. See your Dealer. 4. Electric Power Steering problem. Steering assist not available. Do not drive. 5. All wheel drive system problem. Only front wheels may be powered. See your Dealer. 6. Brake system problem. Brake performance may be reduced. See your dealer. 7. Brake hold problem. Apply brake when stopped. See your dealer. 8. Vehicle stability assist system problem. Reduced traction and handling. See your dealer. 9. Hill start assist problem. Vehicle may roll upon brake release. See your dealer. Thankfully I was approaching an exit ramp and I was able to steer my MDX safely off the expressway. I parked my car on the service road, turned my hazards on and then turned the car off. When I restarted the car the error messages were gone and power steering worked as if nothing happened. Acura will be hearing from me I could’ve been in a serious accident.

When stopped at a red light on a busy off ramp to a busy highway, the car's engine idle function turned the engine off (as anticipated), but then upon releasing the brake, the car did not turn on. I was stalled in the middle of traffic, which is a significant safety issue. I had to turn the car completely off, wait a few seconds, and turn back on. this car is marketing for families with its third row and stalls when stopped. there are numerous reports of this on online forums.

Autostart (stop/start) stopped engine but failed to restart car. Had to shut down computer and restart computer and then car started. Cars were coming around blind corner serving to avoid us. Has since happened multiple times just starting up vehicle (not involving autostart). Taken to Acura dealership 3 times to fix, but they have been unable to resolve issue.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Google on-board gives a persistent error that the MMI and car driving technology firmware cannot be completed. Service center says it’s known and they can’t do anything. The car is supposed to have voice control over vehicle temperature and functionality — it does not. It frequently will not automatically connect to a wireless Apple Car Play or Google Auto connection. Firmware is also supposed to communicate w car speed, etc. to make Acura Assist driving more safe.
