Tailgate problems of the 2019 BMW X3

Two recent problems: (1) the tailgate opened on its own twice. Both times the car was parked, once overnight. No keys were pressed. (2) comfort access works intermittently. Several times, pressing the handle groove evoked a click but did not unlock the car. The door did unlock when I pressed the unlock button on the fob.

First problem is that one three separate occassions my rear hatch/tailgate has opened on its own while parked. Each of the three times the car was parked in the garage and has hit my garage door causing damage. While in the garage, my keys were inside the house and no buttons were pushed on the key fob. I have complained to the dealer about this issue twice now and have not had success in solving the issue. Second problem is that the seat ventilation on the passenger seat has failed three times. Each time the fans within the seat that activate to push air through the vents sound like they are tearing through the seat. Each time the dealer has repaired the issue, only for it to return again. The car is going to the dealer once again after I asked for them to escalate this issue. I have not yet had the car one year. My purchase date was in September 2018.

When slowly driving up a hill, the tailgate opened and the contents in the back fell out.

The tailgate opens on its own. This happens without the key fob being near a person or anything pressing on it. This is a serious safety issue and BMW dealers will not fix it, if they do not see it in person. So, far this has occurred several times while the vehicle was parked in a driveway or in a parking lot.

The tailgate opened by itself while I was driving on the highway. I had a short local driving before entering the highway. About 5 mins in the highway at around 60 mph, the tailgate opened by itself. The car felt very noisy and hard to control (I was on a windy highway). I had to exist the highway, stop on a local street, and close the trunk. The same random opening also happened once in my garage while the car was parked and locked, a week ago. With two random opening happened in one week, I am afraid of driving it. You never know when the tailgate will suddenly open again.
