I am reporting a sudden acceleration event that happened with my 2019 Model 3 in Houston Texas. I was parked in a parking lot with the car in park and doors opened while my wife was getting down. Suddenly the car accelerated and I had to hit the brakes to stop the car after it zoomed at least 100 feet ahead. There were no cars ahead so I did not hit anything or anyone but the tire hurt my wife when the car moved forward.
I am still trying to piece together as to how the car suddenly accelerated while in the park and with doors open. I have been driving for more than 30 years and something like this has never happened so I doubt it is a user error.

I tried to obtain the data logs on the car logging through my account onTesla website, however, Tesla says it cannot provide data logs citing privacy concerns. I made an appointment with the local service center but they also canceled the appointment and said they cannot provide the data.

From what I have understood, Tesla has been subject to lawsuits for sudden acceleration but prevailed with the NHTSA ruling in favor of Tesla.
I am looking for advice as to (1) how to get the data logs that can show what exactly happened – car error or user action error and (2) if it was car/system error, are there any active lawsuits I can join? Thanks in advance.
