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.

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.

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.

- Katy, TX, 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.

Vehicle lost power upon accelerating and I received a message to pull over when safe transmission error; this happened at a stop and seems to be more likely when turning the vehicle or while accelerating, I pulled over and attempted to put the vehicle in reverse with out success;

- Waldorf, MD, USA

Multiple systems indicator failures wen on, per attached pictures. The transmission was stuck in the 1st gear, the vehicle was vibrating and was unable to accelerate. This created a driving hazard, as I was on the roadway.

- Germantown, TN, USA

Vehicle loses power upon accelerating and hesitates for a second or two - most typically from a stop and seems to be more likely when turning the vehicle while accelerating, although there have been times when the vehicle has stalled when trying to accelerate on a straight section of highway. Problem is intermittent, virtually impossible to predict or replicate, but has occurred numerous times since purchase of the vehicle in November of 2017.

We were driving 70mph on the interstate I10 headed to new orleans when our vehicle suddenly and without warning lost acceleration the dashboard lite up like a christmas tree telling me to pull over immediately and then electric parking brake error, transmission error and an emissions error all at once. This was a very dangerous incident and we somehow managed to get to the small side of the road on this busy interstate. It scared the both us! the MDX would not go into drive or neutral? while waiting for the tow truck we almost were side swiped. This car was purchased for the safety features and it has really caused my wife and I to lose all faith and now cannot depend on it. Our vehicle has 44K on it and it was even a Acura certified pre-owned inspected vehicle. I have learned there is a class action lawsuit for this same type of incident and model of Acura. This car is dangerous and Acura better own up to this faulty vehicle. This needs to be recalled!

- Jefferson, LA, USA

The transmission in the car decelerates unexpectedly, the vehicle stalls when trying to accelerate, it also jerks when shifting gears, all of these issues are extremely dangerous when driving on the highway, switching lanes and simply driving and trying to maneuver from a stop. We have also had a warning pop up on the dashboard to immediately stop the vehicle in the middle of the street because there is an issue with the transmission, we took the car to the dealership and they said they dont see the specific code and to just have it towed in next time. I bought this car for safety, we just had a baby and now I am scared to drive the car on a daily basis, what if it doesnt accelate when needed and we get hit! we have brought the transmission issue up mutliple times; however, all we have been told is that this is a normal thing for the Acura MDX 2017 year we have. This is not normal, it is extrememly unsafe.

While driving on the expressway, I have had at least 3 episodes of deceleration while trying to accelerate. I was traveling between 60 and 75 mph. It seems to happen when I decelerate to slow with traffic or change lanes to exit. When I attempt to accelerate, the car (2017 MDX) continued to decelerate rapidly, for up to 5 seconds, putting me in a very dangerous situation on the highway. I was not using cruise control and had the lkas turned off. Additionally, I was not close enough to any other care for the automatic braking system to be a factor.

- Hamilton, OH, USA

I was driving 80mph southbound on 45 in houston, Texas on Sunday, May 26, 2019, during memorial day traffic. Without notice, my car began to ding and stated to 'stop driving'. it also showed a transmission error and parking brake error. In addition, the car shifted into neutral automatically, disabled the gas pedal and I was unable to reengage drive. At this time, the highway I was on was under construction with cement walls on both sides with no shoulder. I was able to coast to the nearest exit and leave the highway. Once off the highway, I restarted my car and was still unable to put it in drive.

Note that the following problems have been occurring frequently since I purchased the car in October 2017; the date required below was a random date I chose. When accelerating quickly to enter a highway, the transmission hesitates before deciding which gear to jump into. This also occurs, to a lesser extent, when I have to stomp on the gas in an emergency situation while on the highway. This is extremely dangerous since it makes me vulnerable to an accident; when I stomp on the gas pedal, I expect to get acceleration. I don't expect the car to pause in order to decide which gear would be the best to jump into. The dealership said the computer was trying to decide which gear would be the most economical, from a gas perspective, to shift into. This is not for normal acceleration, but where I need to accelerate very quickly. Additionally, the automatic transmission jerks when shifting from 1st to 2nd gear. It has been happening since I purchased it in October 2017. When I complained about it to the dealer service center, they said this was "normal" and nothing they could do.
