2023 Toyota Crown Transmission Problems

On September 16, 2024 at approximately 13:20 my mother was driving her 2023 Toyota Crown in the parking lot of the post office and she was slowing down to park in a parking spot when all of a sudden the vehicle lunged, surges, jerks ,speeds forward all on the cars own with no physical driver commands .

I have experienced several instances while driving of Hesitation/Non-Linear Acceleration from a stop. When light turns green, on occasion when I accelerate, the vehicle hesitates then lurches forward into traffic. Have also experienced this issue when waiting to make a turn - car hesitates then lurches forward.

Transmission Vehicle did not respond to acceleration when I turned onto a feeder street causing us to almost be hit Problem did not reproduce when I took it to dealership to be corrected. Please note that the 23 Highlander with this exact engine had this exact problem and I've attached TSB-0087-23 that Toyota developed for that particular vehicle.

Notified Toyota Corp by customer service via phone. Issue with car jerking forward while in Park or in neutral , especially when cold and warming up. Car does not move more than an inch to two inches due to parking paw catching vehicle.

Unable to select Drive when car is moving from the neutral position especially if going through automatic car wash . I've had to stop the car totally to be able to move the car from neutral to drive. I also had to put the car in Park at times from neutral to get the car to shift into drive.This is extremely stressful and sometimes dangerous if a car is behind me.

The same problem for Toyotas creeping forward has happened to my crown. The crown creeped forward while in neutral. I have done it Multiple times to verify that it does happen.
