ENGINE
The engine suddenly shut off when the vehicle was waiting for traffic light and at full stop. The vehicle would not restart after multiple attempts and had to be towed to dealership. Mechanic at the dealership said the "Idle Stop" feature can drain the battery quickly and had to replace a new battery. We consider this a reportable safety hazard and a potential design defect because 1. The "Idle Stop" feature is turned on by default, though it can be manually turned off. 2. The incident occurred in a very abrupt and unpredictable fashion. The vehicle was started normally about 30-40 minutes before the incidents and has been driven normally in a typical city traffic condition till the incidents occurred. During this period, the computer system did not give off any warning related to a total battery failure.

ENGINE, LANE DEPARTURE: WARNING, LANE DEPARTURE: BLIND SPOT DETECTION
While driving on the freeway with my children, the vehicle started to shake and the emission system problem, transmission system problem and blind spot problem lights came on. The safety of myself and children were at risk due to being on the freeway and having to pull over on the side of the road. There were zero signs leading to this.

ELECTRICAL SYSTEM, ENGINE
While driving in traffic, my vehicle suddenly shut down without warning. The engine stalled, and I lost power to steering and braking, creating a serious safety risk for myself and other drivers around me. The problem has occurred more than three time. At the time of the failure, there were no warning lamps a message display showing to continue to drive depress brake pedal and push switch there was no check engine light showing. I had to shut the whole car off open the door and re start the car. The issue has been inspected on 08-13-25 by a acura dealer / mechanic. I was told it was the battery and it was covered under warranty. They found no other issues. The car shut down on me again on 08-19-25 and on 08-30-25 with my family in the car. This unexpected shutdown placed me in danger of a potential collision, and I am concerned that this may indicate a larger defect affecting this vehicle. I can get a receipt from the acura service department if needed.

POWER TRAIN
I was driving at about 65mph on the NJ Turnpike at 7:45pm on 8/28/25 when suddenly the accelerator pedal was non-responsive over a period of about 3-5 seconds. The RPMs dropped (engine did not stall) and the vehicle speed began to diminish. No warning lights showed and the dashboard remained lit as usual. The road was wet from a recent downpour. This was a very scary moment as my vehicle was surrounded by trucks. I further depressed the accelerator pedal and was able to regain control of the vehicle. This is the one and only time this happened with this vehicle as far as I am aware. I have scheduled to bring it to Acura service next week regarding this issue. A Google search has revealed several class action lawsuits regarding this issue.

UNKNOWN OR OTHER
This is a known issue with Acura that they have not addressed. The software cannot be updated due to a flaw in their design. The dealerships cannot even update the software since it is designed to only be updated via a WiFi connection, which does not work. This is critical, because the 2025 MDX is actually a major departure from prior years in how the brakes and other functions operate. When I brake, it is very rough and uneven and the engine revs and surges the vehicle forward. Only a software update could possibly fix this, but this is not possible, due to the lack of any access to the car's electronics. Quite frankly, Acura marketed this vehicle to be vastly superior to prior year models, but they cut out various features (including a hard wire connection to the electronics).

ENGINE
I took my car to get an oil change. When I left the dealership, I heard a rattle I turned around he told me to bring it back in the morning. I went back the very next morning and they told me my engine valves needed to be adjusted. It took them from Monday until Thursday to complete the work and when I picked it up on Thursday the same noise was occurring. I left it there, on Monday they asked if I could come ride with a technician on Tuesday. Technician heard the noise stated they will get it done it was the timing change. From Monday-Friday I went to retrieve my car and the same noise nothing change and I called and told. Took it back on Tuesday they told me it was a lower engine rod that I would need to replace my motor, later went to the store and the car never move out of park gear. Got it towed back to Acura and they wouldn’t help me.

ENGINE, VEHICLE SPEED CONTROL
1. The car accelerates by intself. The accelaration is like "hiccups". When reversing and changing to D gear, it takes longer than usual for the accelarion to take effect. Yes, car is available for inspections 2. It is dangerus because it gets the hiccups even at high speeds. If it is a serious egine problem, which seems like it is, could cause an accident. 3. The car was taken to the dealership for 3 recalls but it got worse after the recalls were fixed. Supposedly the recalls were supposed to fix the issues. We have not taken it back yet. 4. There is no lights or warnings when it does it.

POWER TRAIN, ENGINE
I was driving and all of the sudden I hear a pop and total engine failure. I was lucky to be traveling at 45 mph and could coast off the road safely. After the damage occurred the motor would not turn over again. I had it towed to Acura and they told me my motor was locked up and specifically that my camshaft bearing had failed. I asked about the recall and they said my vin was not selected for the damage therefore there was nothing they could do other than replace the motor at my expense. I have yet to repair this vehicle and it has been sitting untouched ever since it was towed back to my home.

When starting the vehicle, the steering column extends to the operating position. When it extends, there is a grinding vibration coming up from the base on the floor. This is a very troubling sound as the entire dashboard vibrates.
