2023 Nissan Pathfinder Cruise Control Problems

I write to report the issues which are a safety hazard to me & whom ever operates it or I transport in it, Which creates a higher concern for my & their safety . I purchased a 2023 Nissan Pathfinder SL on July 6, 2023 an eight seater model 4WD with 8 miles on the speedometer manufactured by Nissan as per label on door April 2023.The problem I have experienced recently after a month & two weeks now. The vehicle starts are normal but once the vehicle is on the road and is within normal operation temperature. I noticed that I must start applying brakes earlier than usual on where the same roads which I have driven other vehicles in order to stop did not have to do this. Is like if I don't do so & ignore not applying the brakes earlier now I must use greater than before foot pedal pressure that when is stop the vehicle jerks forward like it wants to continue on. Also there is a lost of gas pedal power when trying to enter the highway flow traffic, That since I was almost rear-ended twice already is kind of depressing creepy feeling that now I wait longer or seat at a lane in order to safely enter the flow of traffic or passing. In fear that the lost of power of this vehicle if I try to pass or enter will stall out and put others in danger if it does happen. There is also hesitation, jerking form engine & transmission at high & lower speeds. That requires more attention on the early braking problem I have described above. It seems the pilot assist & stop/start when off are still operating in the background. I have returned to the dealer service center that when he inform that I am not the only one affected. Nissan engineers working on it. The dealer allowed me a temp rental replacement vehicle for now but for how long?
