2025 Acura MDX Owner Complaints

The auto start/stop system failed to restart at a stop light. This was an issue on the older MDX and TLX vehicles with the 3.5L V6 which resulted in a large recall. The recall has not been extended to cover the 2025 MDX and the dealership is refusing to fix the issue or acknowledge it despite having a video to prove it occurred. Acura is knowingly selling these vehicles with a dangerous safety defect that will occur at random. Please consider investigating this matter further as I am concerned for my safety and the safety of my passengers.

Idle stop causing engine to shut down. This has happened three times! It’s very dangerous.

The car sometimes brakes on its own, and sometimes it brakes more or less than normal. Also, sometimes when I try to turn it on, it struggles to do so.

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.

on 8/24, I purchased an acura mdx 2025 technology package.We drove home from the dealer, my mother heard a rattling noise but thought it was the car seat making the noise.The next day,I heard the noise again,it was coming from the right, rear back,I checked,and saw the wheel liner loose and thought the noise was being cause by a loose liner.My mother said we had to go back to the dealer on 8/31 to pick up the wheel lock and weather mats and we would have them check the liner.As the week went by,the noise was more often.On the way to the dealer, we could hear the noise after every bump or turning right.We gave this information to the dealer,we said we thought it was a loose liner but were not sure anymore as the rattling was more often.We did not feel safe driving home.They provided us a loaner and said they would look into it.On 9/4 they sent a text that the rear sway bar link was faulty, the part was ordered and the car should be ready by Friday.My mom emailed them to ask if by faulty,they meant it was loose or broken,they checked and said it was broken.It was expressed to them that this was concerning because it was a brand new vehicle,that we felt blessed that we decided to leave the car,had we driven back home, God knows what could have happened since a broken link can cause you to lose control and get into an accident.We asked if they would report it to the manufacturer or NHTSA? They did not reply. But text a day after stating that we must have gone through a pothole at high speed or hit something,and we were liable for the cost.After my mother sent an email and spoke with them saying that if it was not caused by us,that if the issue was there,was it caused during transporting the car from The manufacturer to the dealer?they said that the car was fixed and there would be no charge but kept insisting that we were at fault,that it happens alot,where people walk out of the dealer and come back with something broken the next day.

The geniuses at Acura / Honda quit installing SiriusXM in the 2025 MDX and instead relies on the user's cell phone paired to the "radio" to get SiriusXM. My issue is that it cuts out when my cell phone doesn't have a clear view of the SiriusXM satellite. Sometimes it continues when reception improves, but most times I have to reboot the SIrusXM app on my cell phone. This quite dangerous in traffic and definitely is not a safe action. I'm quite ready to change cars because I don't want someone to get hurt because of this design flaw. This has been happening since I bought the car in January but is getting more frequent with the foliage on the trees.

My new Acura MDX has very soft braking under normal braking and with harder braking the pedal normally is at the same level as the accelerator pedal which I feel could be a safety issue if your foot is then pressing both pedals at the same time. Also, when driving with adaptive cruise activated, when the car starts to brake on its own following another slower car, with my foot resting on the accelerator, the brake petal will activate and sometimes trap my foot between brake and accelerator petals. This is new to Acura as this is my third MDX since 2014. It has been noted on u-tube videos of the new MDX's. The dealer says it is not an adjustable brake system. The car can be hard to stop with a heavy load. Nothing I have ever experience before with any car.

(1) My airbag's did not deploy when an another car drove into the front of my car causing extensive damage. It has been deemed a total loss by Liberty Mutual (claim #[XXX]) and will be towed in a day or two to their salvage yard from the auto body shop. (2) Based on what I was told by the claim adjuster, body shop and police they didn't understand why they didn't deploy, especially since one of the air bag sensors was directly in front of the impact. (3) No - Acura has not been easy to communicate with and assigned me a case #[XXX] but after I answered their questions by email a few days ago they have stopped communicating with me. (4) The car has been inspected by the body shop and Liberty Mutual. (5) No INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

i purchased the vehicle March of 2025. Since I have been to the dealership on multiple occasions. I was there less than a week after purchase because there was a noise coming from the front tire the dealership balanced the tire. The noise was still there so i returned and the next time they replaced the front wheel bearings. I still have issues with the steering wheel shaking so they replaced all 4 tires. The problem still persists but they don’t know why. the car feels unsafe to drive especially on the highway and in rain. i have had the recall for the brake pin assembly addressed and fixed. I also have issues with the audio shutting off or not responding the dealer did a hard reset and an update to the software that has not resolved the issue. The car would turn off at random times and struggle to turn back on when the idle shut off was activated. the dealer replaced the starter. i have had issues with the car randomly braking when there is nothing in front of me and other safety features either not working at all or working when not needed. dealer advised it was a faulty battery and replaced it. I currently am still having shaking with loud noises especially at higher speed. The engine is very hesitant when accelerating and i struggle to merge onto the highway. It is also extremely jerky at lower gears and its most noticeable in stop go traffic. The brakes are squealing already and the mileage is low. I also sometimes need to press the brakes hard to even stop. The screen often goes black or will not connect to anything and i am unable to see directions or hear music. i feel extremely unsafe in this car and have anxiety every time i need to have anyone in the car with me

When the car comes to a stop, the engine will shut down after idling. This is by design. The problem is that the engine shuts off and does not start up again. This is very dangers when turning across traffic. I took the car in for maintenance and they said this is a known issue but there is no fix. The internet has many complaints and some people are having their starters replaced. This problem has occurred in other model years of this car. Please issue a recall and make Acura accountable for this known issue.

Tires have 3k miles . For the past 2 weeks, we have had a slow leak. Must refill air every 3 days. Spent one day at Tire Kingdom, but they could not detect anything. Then the Acura Dealer says there is a leak, but can't find it. We have no choice but to purchase a new tire. This is wrong - th I am retired on a fixed income and must buy a tire for a 3-month-old vehicle!

The contact owns a 2025 Acura MDX. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond as intended, causing the vehicle to decelerate unintendedly. Several unknown warning lights were illuminated. An independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed, and determined that the throttle body was damaged and needed to be replaced. The vehicle was not repaired. The manufacturer was notified on the failure and suggested that the vehicle be taken to the dealer for assistance. The approximate failure mileage was 6,000.

I am a three-time Acura owner currently leasing a 2025 Acura MDX through Honda/Acura. On or about 12/02/2025, at approximately 16,297 miles, a front parking sensor fell out of the front bumper while I was driving. I am concerned that this reduces the reliability of the front parking/safety system and could put safety at risk if a driver relies on the sensors to detect obstacles at low speeds (parking, maneuvering, etc.) while the hardware is no longer properly secured. There was no crash or injury in this incident, but the failure affected a safety-related system on a low-mileage vehicle. Before I noticed the sensor was missing, the front alert on the dashboard began going off repeatedly while I was driving, even though there was nothing in front of the vehicle. That was the first indication that something was wrong with the system. Only after I parked and inspected the front of the vehicle did I see that the front parking sensor had come out of the bumper, which confirmed the source of the problem. The problem was inspected and confirmed by an authorized Acura dealer, who diagnosed broken internal mounting clips on the front sensor. The dealer and manufacturer attributed the failure to “outside influence” (implying that I must have hit something), but no impact damage or other physical evidence was found on the front of the vehicle. The front remains normal and pristine with no dents, cracks, gouges, chips, or distortion of the bumper, paint, grille, or sensor area. I am concerned that a likely part or installation failure on a low-mileage vehicle is being dismissed as “outside influence” based purely on assumption rather than documented physical evidence. In effect, an unproven assumption is being treated as fact, which could allow similar front sensor or mounting failures on other vehicles to be written off as external damage instead of being investigated as a potential durability or design issue with the front sensor mounting.
