I was on the feeder road of a major freeway in Houston Texas at a stop the brake fully applied. The auto engine idle stop was enabled. When I removed my foot from the brake the engine did not restart. The lights, radio remained on but I was unable to drive my car or change the gear shift. Being on a freeway feeder was a dangerous place to be stalled and had to wait in major traffic for a tow truck to come as the vehicle could not be started or turned off. Completely inoperable. The check engine light was on and oil light. I was towed to a nearby maintenance shop where a p2638 code was listed. After the car was towed the car would restart. Prior to the incident there have been other occasions where the vehicle struggles to restart the engine from the auto idle. However there were no warning lights. Additionally I scheduled service with the dealership the next day and they show an auto idle recall as an item for repair. There is no recall listed on Nhtsa. Additionally I see a class action lawsuit was filed earlier this week for a potential ongoing, long term issue related to this product.

My 2017 Acura MDX has many issues with both the transmission and electrical. It has an issue shifting between gears, makes a loud sound like metal on wash board, then loses power for 3-5 seconds. I went to put the car in drive and it would not go in drive recently. I've now had to replace the transmission at 79,006 miles. The electrical system lights up when driving telling me my electronic parking brake has been engaged and also that there is emission system issues. My daughter was terrified and crying since i had a loss of power at the same time my dash lit up and I had to get across 5 lanes of traffic to the shoulder of road. The towing company had to remove battery cable to get my electric parking break to release. This is a dangerous and scary automobile

- Huntsville, AL, USA

Traveling on I-49 north at approximately 80 mph without any sign of a problem when suddenly the car began breaking, shifted into neutral, hazards flashing, and every light on my dash lit up (Emission system Failure, Braking Failure, and Transmission Failure). At first I thought it had something to do with the cruise control, so I tried turning that off, which did not help, so I pulled over to the shoulder safely. This really could have been dangerous had there been more traffic because the car could not accelerate. Once on the shoulder I engaged the parking break as the car would not shift into park or any other gear. I turned off the car while I called state police and roadside assistance. After a while I was able to turn the car on and move it to reverse because I was about 30 yards past an entrance ramp that I could go to off the interstate. All lights were still lit up on the dash. It sounded rough. This was a very dangerous situation and Acrua needs to address this. It is currently awaiting evaluation at Acura of Lafayette.

- Alexandria, LA, USA

Complete Transmission failure at 77,000 miles. Vehicle lost power at highway speeds causing a dangerous situation and stranded our family 650 miles from home. Had vehicle towed to the nearest acura dealership where I was told the transmission was terminal and needed to be replaced. Three weeks later the dealership has failed to find a transmission and nothing has happened. Acura extended a good faith discount on the repairs 4k down from 9k because it failed just out of warranty.

- Westerville, OH, USA

I was driving on the highway at normal highway speeds of 70MPH when the car lost the ability to accelerate, and I was forced to make an emergency stop on the side of the interstate. With the heavy traffic on the interstate, this scenario could have been catastrophic as there is currently construction and no place to pull over for emergencies. The vehicle was towed to Hubler Acura in Greenwood IN where they performed a diagnostic test and no known issues were found on their diagnostic computer. However, the issue is not happening on a computer at the dealer, the issue occurred on the interstate while traveling 70mph. I have read several message boards where the users have posted similar experiences about losing power when accelerating in their 2017 MDX. The dealerships seem to offer a transmission fluid change or a computer reset as a solution. I have previously had the same acceleration issue and had these two items already completed within the past 90 days and neither issue resolved the problem, which further led to the most recent interstate incident. From my online research, Honda is either unwilling or unable to diagnose this common transmission problem and they need to be held accountable for their inaction. This issue needs to be addressed before it creates a scenario with fatalities.

On March 20, 2022, I was on the freeway going 65 miles per hour in the fast lane and my transmission warning light came on and the car went in to Neutral and lost all power on the gas pedal and the car would not move. I could not put it in Park or it would roll backwards so I put on my hazard lights and kept my foot on the brake. I was almost rear ended several times as it was 9:30pm and no lights on the freeway in the area I was at and no place to get out and find a safe spot as my car would have rolled backwards as it would not come out of Neutral and at that spot in the freeway there is only cement walls. I was able to get the Calif. Highway Patrol to get me a tow company that could tow my car after I called 911. AAA which I have said it would be 90 minutes. I would have been killed before that. The tow truck driver had to tow my car to the Hopkins Acura dealership in Fairfield, CA where I had just had it serviced the Thursday and Friday before on March 17 and 18 for the car's 100,000 maintenance work. The Hopkins Acura said they test drove it after the maintenance work which cost me $3500 but my speedometer showed they only put 1.5 miles on my car so they did not test drive it far. The dealership said they do not touch the transmission during the big maintenance but this car was driving fine and for this transmission to just stop and freeze is so dangerous. The dealership says they will fix the transmission as they spoke to two different companies they work with but they want me to pay $600 of the repair which I do not think is fair.

On multiple occasions (6 times within a week) the powertrain loses power. While traveling 60 mph in 4 lane Interstate traffic engine loses all power and accelerator ceases to respond. Passengers were at risk due to no power. Acura Dealer has not been able reproduce. Some dealers have affirmed that they've had customers with the issue but can't reproduce. The issue seems to occur more frequently after cruise control has been dis-engaged. I have spoken with another a 2018 Acura owner directly and they have experienced the same issue. It does seem the engine/powertrain resolves when the transmission is switched from "Normal" to "Sport" mode. The amount of time with loss of power seems to span about 5-10 seconds.

- Chapel Hill, NC, USA

Vehicle has ongoing rough transmission shifting issues. It jerks between gears when accelerating at stop signs or stop lights. I have also received a letter from attorney alleging ongoing transmission issues with this model - 2017 MDX. Car has only 23k miles. I used your website to search for possible recalls and did not see any. However, I wanted to share my experience to hopefully help others or perhaps hope of others reporting same mechanical issue.

- Rocklin, CA, USA

Driving East on Interstate 20/59 10 miles East of Meridian, MS November 17, 2021 around 2:00 PM. A lot of trucks on the road. Had speed control set at 69 MPH. Came up behind a semi doing about 65, pulled over to the left lane to go around him. When I got about half way all of a sudden all hell breaks loose. Vehicle goes in into emergency stop with lights flashing all over the dash. Vehicle brakes to around 30 MPH within a couple of hundred feet with semi's and cars beside and behind me. Finally got the vehicle over to the side of the rode without and accident. (A miracle inself). Code DTC P0716. After about an hour of shutdown, started engine and all messages were gone. Took it to the Acura dealer and they, evidently, updated the TCM software. I had not been notified that it needed and update which is negligence on Acura. This incidence could have been a catastrophe with possible deaths. Now my wife is really afraid to drive this vehicle.

The contact owns a 2017 Acura MDX. The contact stated while driving 40 MPH, several unknown warning lights illuminated, and the vehicle started to jerk back and forth. The vehicle inadvertently shifted to neutral causing the loss of motive power. The contact exited the vehicle and pushed the vehicle to the side of the road. The contact had the vehicle towed to the local dealer to be diagnosed. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 70,000.

Transmission goes into neutral on its own. Loses power. Delay in acceleration. Jerky gear shifting.

- Branford, CT, USA

We were driving on the highway yesterday at 75 mph when suddenly our tachometer jumped a couple of times and then the car lost all power and switched into neutral. It's the same transmission problem others are reporting and dangerous.

- Sandpoint, ID, USA

The transmission will jerk when driving upon acceleration and has a continuous shifting sound and feeling as though the car is in neutral or the drive mode is being changed (like that when you shift gears on a bike). I am unable to use all drive modes as the issue occurs in every mode--but even more in the sport modes. When the problem occurs, I have to turn off the car and turn it back on and that will usually fix the problem--but if I change it to another drive mode or have it in the sport modes it occurs randomly. If I'm on the freeway during commute times, I don't pull over to do so. The issue first started at 15K miles while driving on the freeway. I was utilizing one of the sport modes. In the past--the ride was smoother, now it's a hit or miss. It was reported to the dealership during a service. This issue has been reported a total of 6 times to the dealership. They have kept the car overnight, replace the shift mechanism, updated system settings, and the gas pump. During my last visit, the service manager stated that no issue was found. The issue still persists. From my research, it is a common issue and should not be. It started back in 2018 and as late as 4/14/2021.

- Fremont, CA, USA

The contact owns a 2017 Acura MDX. The contact stated that while driving at 45 mph, the vehicle stalled as the emission and parking brake warning lights illuminated on the instrument panel. The contact stated that after experiencing the failure, the vehicle resumed normal operation as the warning remained illuminated on the instrument panel. The contact then took the vehicle to lindsay Acura (5880 scarborough blvd, columbus, oh 43232) where they were unable to duplicate or diagnose the failure. The mechanic cleared the warning lights off the instrument panel. The contact stated that the failure persisted soon after the return of the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

- Dayton, OH, USA

Transmission will jerk heavily when driving and has a continuous shifting sound like it stays neutral. Will judder when the vehicle stops and on acceleration. The car needs to be turned off and back on to reset. I can't use all drive settings as it happens more frequently in the sport modes. The issue first started happening at 15K miles. I have reported it to rhe dealership six times, the last time was a week ago. The dealership has kept the car overnight, replaced the shift mechanisms, updated system settings, and the gas pumps. The problem still persists. I attempted to upload service records, multiple documents.

- Fremont, CA, USA

Loses power and unable to accelerate while driving at higher speeds. Has happened 4 times in 2 months

- Lexington, SC, USA

I own a 2017 Acura MDX. When accelerating from a stop it hesitates for a second or two and then jerks when it finds its gear. This happens every time the vehicle is used. Merging onto the interstate or switching lanes can be very dangerous.

After receiving the vehicle from Acura in March 2020 with approximately 49,500 miles and noticed the vehicle was slipping around 20 to 30 miles per hour. My fiancee drove it as well and felt it slipping in a city stop and go under the same speed. We called Acura to complain about the slipping as well as the battery malfunctioning. They told us to bring it in and we did. The battery end up being dead a few weeks after receiving the vehicle. It was changed. We then were told that the vehicle needs a transmission fluid change and that this maybe causes the problem. We noticed with the vehicle records the fluid was changed at 42,376 miles prior. The transmission fluid ended up being changed and we were told that we would need to drive the vehicle a lot for the slipping to go away. Thousands of miles later the vehicle is still slipping with 53,000 miles. We feel Acura knows the is an issue but doesn't want to fix it. We need help. I'm not the only won having this issue with this particular vehicle when it involves slipping. I have a few documents supporting my case about the transmission fluid and the current issues with the vehicle.
