My car has stalled while driving on the highway multiple times now. The first time it happened, it lost power, stopped accelerating, and cycled through multiple warning lights, causing a significant safety risk. I pulled over and it restarted within minutes. I took it to a repair shop and they could not find a problem with it, even with the codes provided. Nothing pointed to a solution. It happened two other times while I was driving my child on a highway where it lost acceleration and then kicked back in. Again, this post, a significant safety risk as always in a fast lane on a highway with my child cars behind me had to hit their brakes to avoid me after this incident. Other times it doesn’t lose power, yet it cycles through warning lights randomly. I took it to the dealer instead of a local shop. They texted me about items that should be fixed per an inspection, including struts and a battery replacement. Complete with a large bill just for diagnostics. Yet, nothing was found having to do with the main problem at hand. Losing power while driving. . My battery is less than six months old. I had it tested and it is fine. My vin is not listed in the recall, but, all of the symptoms match the other recalls of the same year make and model.

While driving at highway speed, the vehicle suddenly lost the ability to accelerate. Immediately prior to this, the vehicle was making an abnormal engine noise, which continued until the failure. "Drive" light turned off and the "Neutral" turned on its own. I tried to get it to shift back to "Drive" and it wouldn't. I pulled off to the side of the highway. The engine stalled and the vehicle would not restart. The vehicle was towed from the highway and we were told to have it towed to Acura dealer in the morning. This incident occurred while Recall 23V‑751 (engine connecting rod bearing defect) was open and incomplete.

We had the recall repair done on the start/stop feature on our MDX and it seemed to work initially. But recently the feature has caused the vehicle to stall at intersections again as it did before. It’s happened at least 3 times in the last six months with the most recent occurrence being on 1/20/2026. These occurrences happen despite the fact that we try to remember to turn off the feature when we start our trip. Each occurrence has stalled the vehicle at a traffic light in rush hour traffic. It’s very frightening and we are lucky that it hasn’t caused an accident or gotten us shot! We live in Texas (funny but not).

Since the purchase of my Acura MDX 2019, the following problems have been reported to the dealership and to Honda Manufacturing Inc. without any resolution. The dealer shop has replaced recall parts, but the problems persist and have not gone away. The vehicle stalls and stops working while driving. The engine makes knocking/rattling noises upon becoming disabled while driving.The engine would randomly not start when turning it on. When car becomes disabled the dashboard lights up warning lights displaying messages intermittently of the following problems: Anti-Lock Brake System Problem (ABS), Vehicle Stability Assist (VSA), Hill Start Assist, Trailer Stability Assist, Collision Mitigation System, Road Departure Mitigation System, Adaptive Cruise Control, Lane Keeping Assist, Brake System, Brake Hold System, Electric Parking Brake, SH-AWD, Keyless Start System and Power Steering System (EPS) Problems, while displaying ACC and LWKS codes. Additionally, the vehicle runs improperly and shuts down completely making the window, doors, etc, inoperable while passengers are inside locking me in and my entire family for long periods of time. A few times has left me either myself or with my children and dog inside. The only place where I take my car for services is where I purchased it (Chevy Chase Acura). The issues noted are the same reported by the recalls I have received, and I have not taken it somewhere else because of that reason. Nobody can fix them as the problems are manufacturing issues that even Acura/Honda cannot repair. This safety defect can kill or seriously injure me, my passengers, and other drivers on the road. As noted in one of the many recalls the fuel pump defect can cause the vehicle to stop in the highway and could prevent an engine from starting or cause a vehicle to stall while being driven, it potentially increases the risk of a fire, crash, or injury. My car continues to have these issues and nobody is helping me. Please help!

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.

My 2019 Acura MDX with 100K miles stalled on the road with several alerts on the dashboard and went into Parking mode with no further movement. Had several alerts stating Transmission failure, Blind Spot monitoring failure, Auto break system failure and vehicle stalled on the road. Had similar issues previously where the steering jammed and vehicle was stalled on the signal, took it to Acura dealer and they had to fix some circuit / reset the circuit board. Was ok for few months and last week the car stalled with Parking sign on. Towed the car to the Dealer service center, they diagnosed and identified there is a failure with transmission. They quoted around 10000 dollars for replace new and 7000 for used transmission. This is huge money, hence called Acura customer care for any review/support but they claimed this issue is not in their current recalls or claims, so cannot support. had to pay out of the pocket. Per google there seemed to be a lawsuit with Transmission failures with Acura 2019 mdx vehicle. Acura customer relations is asking to get into the law suit group and Acura as such cannot help the customers with these problems. Had Lexus for several years with no issues and very upset/annoyed with these type of repairs within 100K / 5year old.

In February 2024, received a recall for fuel pump module, which can result in prevent engine from starting, cause vehicle to lose driver power, or stall while driving. Can also result in failing emissions inspection. Acura reports that repair is not available until Fall 2024. In October 2024, while at a stoplight, auto idle-stop was engaged, and engine stalled and would not turn on. Vehicle needed to be turned off and then engine started at that time. A previous recall that affected auto idle stop was addressed in May 2023 where engine does not auto restart after entering auto idle stop. In April 2023 Acura provided a software update, however in October 2024 the engine stalled as mentioned above. Additionally, a local emissions test was performed and failed around April 2022, and passed a second time when performed a few weeks later. Even after experiencing symptoms of recall 23V‑858, recall has not been able to be addressed. This vehicle was brought into Acura in November 2024 for an another recall (23V‑751) and I was told that current unaddressed recall may be available within the following month but could not provide any further assistance. Engine stalling at a stoplight puts my family at risk, as well as others. If engine is stalling at a stoplight, engine may stall at other times, including while driving, increasing risk of accident. Recall has been undressed for almost 10 months.
