VEHICLE SPEED CONTROL, POWER TRAIN, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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."

POWER TRAIN, FUEL/PROPULSION SYSTEM, ENGINE
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.

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
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.

VISIBILITY/WIPER
At night the camera on the rear hatch produces a blurry picture. During the day it is clear. It always happens. I’ve taken it to two dealerships and they could not reproduce the issue because it needs to be dark around the car. I’ve brought in photographs. And they still can’t find an issue. On line there are many complaints about this issue. I can’t see if someone walks behind my vehicle.

While in traffic the auto start sometimes fails to engage and the car stalls. Battery lights come on and the car goes into neutral on its own. I have to sit there and wait about 5 minutes in traffic before it restarts. Battery checked out fine. It has happened 3 times now. This is dangerous, and can/will cause a collision.

ELECTRICAL SYSTEM
When stopped at a light or in traffic the vehicle engages the auto idle feature. (turns off the engine to save gas). Upon releasing the brake, the car should re-start, instead the car does not start. The car jumps out of the drive gear into neutral on the transmission. The electrical system goes crazy and does not allow you to either turn off the car's electrical system or re-restart the car using the car's on/off button. This has happened to me at least 5-10 times over the last year. Each time the car becomes immobile in the middle of the road or highway for up to 2 minutes, until the electrical system resets and allows you to turn off all the power and re-start the car. It's a very scary and dangerous situation, when my vehicle is stranded in the middle of a highway or a road for up to 2 minutes, as traffic tries to avoid crashing into my vehicle. Searching online, I was able to see that this same condition has affected many MDX owners but Honda does not seem to have recall or fix for this issue.

UNKNOWN OR OTHER
In stop and go traffic on a highway, the car went to auto idle mode, then shifted to neutral by itself instead of restarting to drive. This was a safety issue in that I was on a major 4 lane highway with my kids and could've been hit from behind. The only thing I could do was completely turn off and restart the car. There were no warning lights. It has not been inspected by the dealer yet. There have been similar reports of this occurring: https://www.mdxers.org/threads/2019-mdx-auto-stop-feature-causes-car-to-stall-or-shift-to-neutral.175759/

ENGINE
The auto stop feature is enabled by default when the car is started. When stopped at a traffic light or in a traffic jam, the auto stop turns off the engine and is supposed to restart when the drivers foot is off the brake. The engine unexpectedly will not restart, and the car must be put in park, turned off, and restarted. This is dangerous in heavy traffic. The dealer replaced the battery as an attempted repair. The problem reoccurred. The dealer then updated the software, which also did not solve the problem. The dealer advised that Honda is aware of the problem and currently has no solution. I was advised to manually turn off the auto stop feature until a solution can be found.

ENGINE, ELECTRICAL SYSTEM
On a few occasions, while at a stop light the auto idle engaged. When I lifted my foot from the brake pedal, which should restart the engine, the car Shifts automatically into neutral and cannot restart the engine. The dash shows a message saying that I must now shift to park. I have to then turn the car off, while in traffic, and then restart. This happens while in traffic, causing everyone behind me to wait or drive around. I have taken this to Acura of Stamford twice already, and they cannot recreate it. I have pictures of the car when it was in neutral. Other people have reported this occurring on a 2019 mdx as well.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
I was driving my car with my infant daughter in the backseat. We were stopped at a red light in the middle of a busy intersection. The car was in idle mode. When I went to turn left the car shifted into neutral. I could not go into drive. I had to turn the car off and turn it back on again to get it to move out of the intersection. We almost got rear ended. When my husband brought the car in the shop they ran diagnostic testing and said nothing was wrong. Only that the problem may be caused by a low battery. They replaced the battery and let my husband drive home. I want to know why there was no low battery warning light? Also why do I have to almost have a collision to find out the battery doesn’t work?

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
I have had problems with the car stalling or shifting to neutral from drive after the auto stop feature is engaged. This typically happens when the engine tries to restart after having shutoff at the stop. It is difficult to replicate the problem and the dealer can't seem to replicated the problem but it has happened to me many times, particularly in hot weather or after long drives. Typically it happens after a long drive or a lot of around town driving (maybe when the engine is hot?). The dealer does not believe it is related to the fuel pump replacement but that is when it seemed to have started happening but this is entirely speculation. Very frustrating as I have been to the dealer 3 times with the problem and they cannot "replicate" it. They supposedly also replaced the battery and updated the software in the car but that has not solved it. I am growing concerned because it is very dangerous, particularly when stopped at a busy intersection. The last stall happened and it took a minute or so to get the car running again at a busy and large intersection. I am also worried about the happening when on an incline. It doesn't happen all of the time, sometimes there is just a hesitation but the car starts and lurches forward. I have a 2019 with about 35K miles on it and have used primarily for long distance trips and not much around town driving. I have attached the dealer work orders for the three visits but stopped bringing the car in because it has been a waste of time as they are unable to find the issue. Also, I have reported the issue twice to American Honda and they have sent me back to the dealer with no results. This is a dangerous situation and I noticed that there is a related recall for the Acura TLX model with the same engine. This problem is ongoing and has happened to me twice in the past 2 days if I forget to disable the auto shutoff feature. Thanks.

STRUCTURE:BODY:HATCHBACK/LIFTGATE:SUPPORT DEVICE/STRUT
Rear tail gate lift motors are overheating and won't open rear hatch. The motors will lift the gait for about 5 or 6 openings, then the gate will not lift at all. The vehicle has to sit overnight for the system to "cool down". Once it cools down, the tailgate will operate the next date, but will operate only once. The car has to once again, sit overnight, in order to lift the tailgate 1 time. If the motors of the gate are overheating, this is a safety potential fire issue. At this time I am being told the motors are on back order, and I have no manual override in this vehicle to lift the tailgate hatch. If the same motors are being put back in the vehicle, without any modifications, this will not suffice.
