2023 Toyota Crown

When driving the vehicle under normal load and conditions, after coming to a complete stop- then trying to accelerate to take a turn or move forward- the vehicle begins to proceed then suddenly stops moving or accelerating. Twice now I have almost been T Boned. Once when leaving my neighborhood and trying to proceed onto the main 45mph country road, most recently tried to turn left from a turning lane across 2 oncoming lanes of traffic. The car just sat there blocking the road for about 5 seconds despite having the gas pedal pressed. I do have a case opened with Toyota, however, the dealership said there is nothing they can do about it since they couldn't replicate the issue and Im stuck with it or I can sell the car. This is so dangerous. There are TSB issued about this, but what can I do since the dealership said "no code, not their problem". There are not many of these cars around since their introduction in 2023. I don't know if I need another dealership or how to get someone at Toyota to take this seriously. There is also a Toyota Crown forum and can see others have experienced the same issue. HELP. I love this car, but it is not safe.

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 . The car races forward all on its own while she is slowly pulling into a parking spot jumps the curb and crashes into a brick wall. The CVT ( Continuous Variable Transmission ) Is the problem and quite sure.

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. I have almost had an accident due to this issue. According to Toyota Crown internet forum, this is a common issue with the 2023 Crown Platinum and Toyota is not being helpful in dealing with this safety issue.

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. AGAIN, THIS TSB IS NOT FOR MY 23 CROWN HOWEVER, MY CROWN IS EXPERIENCING THE SAME ISSUE. Vehicle was inspected, 28 May 2024, invoice # 1780495 and service said "could not verify customer complaint at this time. No codes to diagnose at this time. No repair recommendation due to current codes There were no warning lamps, messages or other symptoms of the problem. First appeared 18 May 2024. Took to dealership for evaluation/correction on 28 May 2024.

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. Difficult electronic gear shift to operate. Issue with not being able to get car back into drive from neutral especially if on moving tracking car wash. Usually, I have to turn off car while vehicles in motion. This is very scary when another car is behind me. Last time the car wash had to come to a total stop until I put the car back into neutral. Notification to dealer about the issue.

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. Notified Toyota Corporate and plan to take to Toyota Service to help diagnose why this is happening. Also, car has a tendency to move forward when warming up in park and the engine is cold. It does not go anywhere because the Parking mechanism keeps the car from moving anymore forward. This is less noticeable when the Parking Brake is on while car is warming up.
