First Transmission Problem on Touring? Jumping into Park itself

Just picked up my top of the line Touring today and within 3 miles of driving it off the lot, I was reversing out of a parking spot in a shopping mall and then pressed the brake before pressing the button for drive, as usual. Then the car suddenly halted to a stop and I saw that the transmission had jumped into Park by itself. So I pressed the brake again and pressed Drive again and as soon as I lifted my foot off the brake, the transmission would jump or throw itself into park by itself. I pressed the accelerator and nothing. Tried it again but tried to put it into Neutral this time so I could push it off the laneway where I was embarrassingly blocking traffic and getting honked at. But same thing...I even saw the light go from the Neutral to Park by itself. Turned off the car and tried again and same thing. A mechanic came by and said he could help until he saw the new Honda transmission and all he could offer was to push the brake pedal harder to disengage the brake but still nothing. We checked the parking brake, made sure it was off and the parking brake hold was off too throughout this episode.

Anyways, with a baby in the back, cars lining up and honking, I called Honda Link who connected me to Auto Assistance who offered to call the Police and a tow truck. After about 20-30 minutes with the assistance of a number of drivers offering to push the car (but seeing that the car couldn't even stay in Neutral), I turned off the car again, powered on, and then pressed the brake before pressing the Drive button and all of a sudden it worked. Drove 5 minutes back home and now scared to touch the $50,000+ car. Man, how I miss the traditional shifters.

Has anyone experienced this and is it a transmission electrical problem or hopefully as a newbie to the 2018 Odyssey, did I press something incorrectly? Please help since we were planning to do some family driving trips in the Odyssey and now I'm scared to drive the thing. haha...after 20+ years of driving, I've never been scared to drive until today....at least let me leave it in neutral so I can push the car. Wow!

After doing a much of research, my guess is that it could be a malfunction of the Odyssey automatically shifting the transmission to Park assuming the driver parked but forgot to take it off Drive. Or something with the parking brake engaging by itself and not disengaging.

Any thoughts??

Thanks everyone for your helpful responses. This is a great forum.
As an update, I went to the Honda dealership the very next morNing and they found out that my driver door sensor software wasn't working. So
When the door was closed, the software was indicating it was OPEN causing the car, as you all correctly mentioned, to go into Auto Park. While waiting at the dealership for 1.5hrs, i read the manual from cover to cover and saw the Auto Park halfway through. They should put that up front in the manuAL and to be honest, I don't think it's necessary. Good maybe for new teen drivers as they learn but not needed for that elderly man in the new Jeep and experienced drivers that never ever had a problem with a flying door. My 2 cents. Anyways i was glad it was a safety feature problem versus an actual transmission problem. So problem solved! Or so I thought....
The problem only took 1hr to fix and i drove it 3 hours that same day.
No problems until we almost arrived at our destination and as we did a slow left turn, the car went into D2 and got stuck. Rpms went high and the car wouldnt automatically go to 3Rd gear as we completed the turn. Pressed the Drive button to go though the other options and back to normal Drive (all while still driving) and it corrected itself. Thank God! Hmmm....another safety feature, if my left turn light didn't blink long enough?!
Anyways hoping it was just a hiccup. Will watch and update you if it happens again.

Otherwise, it's an awesome car for family vacations. 10 speed Transmission shifting was smooth and responsive, great hp when needed, used a 1/4 tank after 3 hours of driving and the kids loved the bluetooth audio, chrome cast worked to play videos off our cellphones, and liked the Cabin Watch and Talk more than I expected. Definitely fAR quieter than other cars I've had. Wife wasn't used to it and had her ears popping and said she felt like she was in a bubble. Steering wheel shakes a bit too much when out of your lane but maybe have to get used to that.
Anyone experience the D2 sticking issue or read about it in the manual?

Gyro please update us once you know more. Curious to know whether it's an issue with the transmission or not. Thanks for posting.

Thanks for the response.
Sounds like that could totally be it. My wife was driving at the time so makes sense. We haven't noticed it since.

Really been surprised how useful the kick trunk has been on this trip, having numerous times with my hands full of camping or beach stuff.
Sounds like you may have inadvertently hit one of the paddle shifters while turning. Most cars will no longer upshift once you switch to manual mode. Hitting Drive on the shifter would put it back into auto mode.
