2020 Lexus Es

Not sure if I have the right things checked. Starting about december 2022 i experienced the car "lunging" forward upon putting the car into drive, After having backed out of a parking space. It continued to do this off and on even through today. It seems to do it most after the car has been sitting for a good length of time.Perhaps overnight, or while i've been in a shopping mall 2-3 hours. I have four invoice tickets from the lexus dealer where I brought the car in specifically for this problem. They had someone to drive it with me in the car, and of course we were not able to duplicate it at that time. I left the car with them for 3 days on one occasion. And when I returned, they said they had driven it, and did not have the problem. The occurrence has become more and more often. When it started, it was like a few times a year.And now it is almost daily. My concern is that if I happen not to have my foot over the brake as I am coasting, after backing out of a parking space or my driveway heading down the street, and someone is in front of me that the "lunge", depending how close I might be on someone could cause me to ram into the back of their car. I also taken the car in on more than one occasion and have the invoices to support this to say that the car has a very rough Ride I call it "bumbling". Again, they did not feel it.However, two years ago, they said, oh, you just need new tires. I bought them. Less than year later, those tires were worn and they said, I needed new tires. I was able to get deal with the michelin company and only had to pay twenty five percent of what it costs For a new set of tires. So the bumbling is still going on.After purchasing new tires about a year ago. I conclude that there is something wrong with possibly The transmission that causes the lunging and the bumbling has something to do with the suspension. I am not a mechanic, and I have not had it looked at by another mechanic. I need some resolve for this.
