I turn my car on To go to work realized I didn’t have my phone. Car was in park. I hadn’t touch the gearshift at all I get out of the car. Approximate 20 seconds after I walk away from the car, my home security camera shows the car creeping extremely slowly backwards up into my driveway going up across the crown of the road… across the street and falls into a 10 foot deep ditch. I am 100% certain that Car was in Park… There were no sounds when I open the door to alert me that it would be anything other than park.. The back up camera was not engaged, so it was definitely not in Reverse… When the tow truck pulled it out of the ditch, it was Still running It had stopped vertically before it hit the bottom of the ditch, and rear tire got stuck in muddy water…. There were no ruts from tire, spinning from the front end at all in the ditch or the grass above the ditch… There is a recall of some 2020 civics for brake failure, parking brake failure…. I strongly believe my car needs to be part of this recall, because obviously something is wrong… My road is 55 mph and a car had to stop to avoid hitting my car… I have video from my home camera That shows a clear delay between when I get out of my car and shut the door and the car starts crawling. I tested it after he pulled it out of the ditch just to see if I had it in reverse from the same exact spot wouldn’t move and it immediately moved so I’m certain something is wrong… Right now the body shop can’t even duplicated can’t even get it to get caught between Park and reverse. Please investigate And this could’ve easily been a fatality. I need to send more photos and videos, but it won’t allow me to do it but there’s definitely more for me to send If someone can give me an email

i have experienced multiple issues with the sensors since I've had this vehicle in December 2020. The sensor issues have caused my vehicle to shut down and slowly stop as I was driving on the freeway. The latest incident caused my airbag to deploy without any reason while I was driving slowly in a residential parking lot. It went off in my face and I suffered from hearing problems. I am fortunate that this incident did not harm anyone as it put others at risk from the airbag unexpectedly blocking my view and distracting me from driving. Although the dealership, Tempe Honda, repaired the other sensor issues, they refuse to repair the airbag issue. They are claiming that I need to have my insurance pay for the repair. I have had two mechanics inspect the vehicle and confirm that this is a defective airbag sensor that caused the airbag to deploy. I have not driven the vehicle since this incident as it is unsafe for me to drive. The vehicle is available for inspection at any time. I have contacted Honda on multiple occasions. They have Case #12968314 is my case number and every time that I call, the representative tells me that a Case Manager will call me but I have not received any calls. I also sent an email to Honda on 02 May 2022 detailing this incident that occurred on 14 April 2022.
