After driving for an extended timeframe (approximately 3 hours, trip was traveling between Des Moines, Iowa and Kansas City, Missouri) at Highway/interstate speeds, upon slowing down from those speeds, the vehicle goes into limp mode and check engine light begins blinking. After pulling over and turning car off and on again, normal behavior resumes. This has happened both as I arrived in the Kansas City area, and upon my return home to the Des Moines area. Depending on circumstances for when vehicle enters limp mode, there-??s a significant risk of causing an accident. Dealer was unable to pull any codes and therefore is unwilling/unable to address the issue.

2 Issues: Transmission shifts hard between 35-50mph and 50-60mph. Dealership accused me of utilizing improper gas which is not factual; this car has only received the recommended premium octane gas since I purchased it as a Certified Pre-Owned vehicle. Recall: vehicle is currently under crank shaft recall. In the original notification, Acura stated parts would be available in April. Per the Acura dealer, Acura told them parts will not be available until October. This timeline is unacceptable for such a serious safety recall (risk of fire/crash). I feel unsafe driving this car and am worried I will not get fair market value with the recall still open.

While making a very normal commute, my 2019 Acura MDX began running very roughly, slowing rather abruptly. The check engine light began flashing, and several warning messages were displayed on the message center of the vehicle display unit. The vehicle would not accelerate, and would not attain a reasonable speed while in traffic. With the hazard lights on, I was able to move to the side of the road, but it was very difficult as I was unable to exceed 15-20 mph. The vehicle was taken to the dealership for repair. The dealer investigated and found the timing belt had "jumped time" causing the engine management system to set multiple misfire codes, and was described as the cause of the failure. I am aware certain 2018-2019 Acura MDX models were recalled for timing belt issues, but this particular vehicle was determined to be outside of the group of vehicles involved in the current recall. My MDX had 52,600 miles at the time of the incident. It has not had any modifications or repairs to the engine prior to this incident. Acura recommends replacing the timing best at 100,000 miles.

Starting having an issue over the last few weeks where the car will shut off as it should with the idle start/stop enhanced but when I release the brake, the car goes into neutral and doesn-??t start-?? have had this happen 4 times already and was finally rear ended today due to this fault.

- Homestead, FL, USA

My car was purchased with 12,000 miles and supposedly worn tires. Because of that, I went to the dealership to get new tires and an alignment since the car was always pulling to the right. My car has been at the dealership four times for the same problem, and they still haven't fixed it. My car continues to constantly pull to the right, and when I use the cruise control, it stays above the other cars to the right, causing it to suddenly pull to the left, deactivating the speed control and losing control. The dealership's recommendation is to stop using the speed control."

I pulled up to a stop light at a busy intersection/highway exit and, after depressing the brake, the vehicle abruptly turned off and shifted to neutral. The brake became very difficult to depress and the parking brake enabled on its own. The entire dashboard lit up and the car would not shift or respond to any input. The vehicle would not turn off, turn back on, or shift for approximately 15 minutes. After this, I tried to turn the car off and it finally did, I started it again and was able to pull off the roadway. We just recently (within the past 2 weeks) had a recall done to update the auto-stop system. This occurred 1x prior to the recall and now this has happened again. My young children were in the car both times and this put us all in danger.

Vehicle was stopped at a traffic light (transmission in Drive) and the automatic idle shutoff engaged, turning off the engine. When the traffic light turned green, the brake was released and we found that the transmission had shifted to neutral and would not shift back into Drive. We had to restart the car. Being stalled at a green light is a serious safety hazard as approaching vehicles would not anticipate my vehicle being stalled.

- Brandon, MS, USA

During Idle stop at red light car stops and goes into neutral and engine stalls. 2019 MDX won't move unless completely restart the car in the middle of busy intersection. High risk for accident and injury. There is few recall mention in Acura site for 2019 MDX, but when input vin number its claims no recall to this vehicle. Need urgent help.

Acceleration has a very slow response after pressing gas pedel, transmission is very jerky only 12000 miles on car. It can lead into accidents at traffic or other

I think this recall needs to be expanded: Honda and Acura have recalled 2019 and 2020 vehicles including the CR-V and Accord for fuel pumps which can malfunction and cause the engine to lose power. My wife recently had her 2019 MDX stall on her in an intersection and she had to turn off the car and turn it back on so it would work. It sounds exactly like the below: -??While driving, the vehicle shifts into Neutral, the transmission indicator comes and DTC P0657 (actuator supply voltage circuit/open) is stored. The driver will not be able to select any other gear until the vehicle is turned off and restarted. Update the PGM-FI [programmed fuel injection] software and the TCM software, clear any DTCs [diagnostic trouble codes], and do the PCM [powertrain control module] idle learn procedure.-?? - TSB 15-034 Additionally, May 23, 2021 we had an experience where the same MDX decelerated as we merged into traffic at I-30 and I-820 in Ft. Worth. I let off the accelerator going 60-70 MPH and then stepped on the accelerator to complete my merge and there was no power. Speed dropped to around 20 almost instantly. I had to completely let off the accelerator and depress it again to get going. Very scary situation considering how fast people drive on Texas freeways. These are two big issues Honda/Acura needs to address ASAP as both put consumers at risk of injury and possibly death.

Vehicle goes into 'go limp' when I accelerate or change lanes. Very dangerous situation when passing on a two lane country road (happened twice) and merging onto a highway with a short entrance ramp. This could potentially lead to a major accident and we don't feel comfortable driving this vehicle in these situations.

Transmission is constantly slamming into 4th gear and has been to the dealership 3 times. Corporate has even evaluated in and has deemed it to be "within specification". the transmission is going to break down while driving and pose a safety hazard. It feels as if the mounts are going to break off when it does it.
