Power Train problem #1

I entered a large, strip mall parking area and was driving at the vastly reduced speed one would use in such a situation. My intention was to park my car to enter a store in the mall. I turned a corner to park on the side of the building (parking options were limited). As I entered a parking space (moving at the speed one would drive to do so; essentially incredibly slowly; moving forward into the space at almost 0 mph and already applying the brake). Suddenly and with no warning, the car violently lurched forward at a vastly increased speed. I pressed down on the brake harder to try to stop the vehicle, but it propelled into and over the concrete curb stop and into the thick brick wall in front of me. There is considerable damage to the front end of my vehicle as a result. I was horrified at this dangerous situation. My safety was definitely at risk. I feel very fortunate that I wasn't seriously injured (and that no one, either a pedestrian or another driver, was involved in the accident). The airbags didn't deploy and I was of course, wearing my safety belt, which kept me from any severe injury. I do feel some physical injury effects this morning however (sore neck, shoulder, back; a slight headache). I'm not aware of any warning lamps, messages, etc. Going off, but I must say everything happened very quickly. I've reported the accident to my insurance company & filed a claim. Given that the incident happened on the evening before the July 4th holiday, my insurance company scheduled vehicle towing (flatbed) for my car. It's my understanding that it's being stored at the tow company location & will be delivered tomorrow (Wednesday, 7/5/23) to the certified body repair facility recommended by my insurance company and chosen by me. An insurance adjuster will be doing their evaluation, likely in the next few days, at the earliest tomorrow morning. I've also advised the insurance company of these details & told them of my safety concerns and fears.

Power Train problem #2

Stopped at red light, then the car didn't accelerate when hitting gas. Engine revs but the car does not accelerate. It happened multiple time when the car was out in sun with full ac on(100f). Happened once in intersection and almost got hit head on.

Power Train problem #3

The gear would shift either from 'drive to neutral' or 'reverse to neutral' this happened more than 10 times when I had my sister, mother, and father in the car. 1) it happened when I was pulling out of the garage (about 20 degree angel) going up the hill. I went to pick them up, all 3 pf them went in. I had my foot on the brake and gear on drive, when I let go of the brake the gear shifted automatically on neutral. After, 3 tries, the car finally was able to go forward without struggle. 2) I was trying to back in one of the spot (flat ground), foot on the brake, gear on reversed. When I let go of the brake the gear shifted to neutral automatically. I struggled for 3-4 times before the was able to hold on reversed and park the car safely. 3) when I was in the middle of the intersection (flat ground). I had my foot on the brake, when I finally was able to make a turn, my foot on the foot and gear on drive, when I let go of the brake the gear shifted to neutral of the the sudden, I had to try 3-4 times before it was able to move forward without a struggle 5) I was on a hill (about 20-30 degree angle) facing up. My foot was on the brake and gear on drive, when I let go of the brake the gear was shifted to neutral. I struggled for 5-10 minutes (going from drive to neutral back in forth) as my car was not able to hold drive mode, I eventually asked my family to get out of the car as I was getting worried and frustrated, my family was out of the car but I was still struggling, in the process I hit a car behind me. 6) I was finally able to park the car in with any passengers and somewhere flat ground. I left my car for 30 minutes and came to drive my car. I started my car, I had my foot on the brake and gear on drive. I let go of the brake then my gear shifted to neutral again, I struggled for 3-4 times before the car was able to hold on drive.
