| Jan 2025 | ENGINE | Bought vehicle new in 2018. Starting in 2020, brought car to dealership complaining that car, at times, did not accelerate when prompted. Vehicle pauses, then lurches forward. Very dangerous when making left turns and when merging with traffic. My wife (who used to be primary driver of this vehicle), refused to continue to drive it ...and neither I nor my wife would allow our now age 21 daughter to drive it. So this vehicle (as unsafe as it was) became my back and forth to work vehicle. Vehicle was brought to the dealership on at least 4 or 5 times with this complaint - from 2020 through 2024...One time it was at dealership for almost 2 weeks Dealership would never fully admit to the issue - often times one service person, through test driving would notice the issue, only to then be told it was "normal driving" of this vehicle. On a regular basis, car would stop (pause) "in the face of oncoming traffic - my heart would skip a beat, only for the car to then resume accelerating On many occasions, I discussed with service team - always to be told that there were no known issues Fast forward to 2024 - when Acura notified me of a Recall regarding the Fuel Pump....I quickly scheduled an appointment, brought the car in this past week and had the Recall done. Speaking with the Serviceperson when checking the car in, I brought up the past issues that I have had and asked if this Recall was the likely reason.....the service person - without hesitation said "absolutely"......I then asked him, so was "Acura lying to me ll these past visits".....his response was "sounds like it to me" Since getting the car back - the hesitation has stopped. I have paperwork from all my previous visits - with responses from their technicians I am certain there was consumer fraud conducted by the dealership I bought and serviced this vehicle from (Open Road Acura - Wayne NJ). Add to it , the inconveniences I experienced and the fear that my wife and daughter had of the vehicle. | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN | From a stop, the vehicle will lurch forward after 1 second of acceleration without a change in the amount of pressure on the gas pedal, as if there is a delayed input to the throttle position. This only happens from a complete stop, such as at red lights, stop signs, or in heavy stop and go traffic. On multiple occasions I have almost rear ended the vehicle in front of me as a result of this. There are no warning lamps or error messages displayed in the gauge cluster. I have not been able to have this inspected by any of the Acura dealers in a 25 mile radius, because when I called to make an appointment for the connecting rod bearing recall, the earliest opening was March of 2026. | Crash: No Fire: No | Unknown |

| Dec 2024 | FUEL/PROPULSION SYSTEM | We have two stop sale safety recalls on our 2018 Acura MDX that have gone over a year without being addressed.

| Sep 2024 | FUEL/PROPULSION SYSTEM | The car periodically loses power while driving. In traffic this has caused some very scary and hazardous incidents while vehicles zoom around us or as we attempt to make it to the shoulder of the road. We do not get warning lights when it happens. The dealer (Cincinnati Columbia Accura) has confirmed the fuel pump safety recall but has done nothing to fix it. | Crash: No Fire: No | Unknown |
| Sep 2024 | FUEL/PROPULSION SYSTEM | 1.) I have had repeated, on-going issues with the fuel propulsion system since the day I bought the car. When I step on the accelerator it randomly (lately more constant than random) does not respond, then it will shoot me out into traffic. For example when I am entering the highway from an onramp, I see my opportunity to merge into traffic and I step on the gas - nothing - no response, then it suddenly accelerates and shoots me into oncoming traffic. This is SO BAD that I am afraid to drive the vehicle. It is DEADLY. I have reported the issue every time I have had the car serviced (always dealer serviced, from same dealer where I bought it.) 2.) The vehicle will randomly decide that I am going to hit a car in another lane, and will forcefully apply the brakes (when there is no issue, no danger, no possible way I am going to even be close to hitting another car) causing the cars behind me to come extremely close to rear-ending me! Or the car will decide I am going off the road when I am taking a soft curve, and it will sound a warning and try to turn the wheel. 3.) The display panel will go black for no reason. I then cannot use the navigation screen. It will randomly return after a few hours or after a day or two. 4.) The camera/display will get stuck on the reverse camera causing a visual disconnect as I drive forward, but can only see what is in reverse. (like seasickness). No idea what causes it or how to fix it. Eventually it corrects itself after a few hours/day+. 5.) Car will occasionally make a strange squealing noise after it has been turned off - no idea what that is, or what causes it. As a salesperson who spends many, many hours in her car, this vehicle has become a constant danger to both my livelihood and my life. I am afraid to drive it and I will not let family members drive it as I am afraid for their lives due to the issues stated above. | Crash: No Fire: No | Unknown |
