Lexus IS250 Vibration Noise during Acceleration from Stop

[Imran Patel]

Hi,

Lexus IS250 2.5 V6 2009 Petrol Automatic Transmission

I recently observed an audible sound accompanied by a noticeable vibration when accelerating forcefully from a complete stop. I'm concerned whether this is a problem with the transmission or possibly related to the brakes. This phenomenon only occurs when starting from a complete stop and lasts for approximately one second. I have attached two videos: one demonstrating the sound and vibration when the gear is in "D" with my foot on the brake, ensuring the car remains in gear without movement, and the other video shows the sound produced when I apply fast pressure to the accelerator in order to move the car.

The first video is when the car is in gear position 'D' and foot is on the brake whilst the accelerator is pressed.
The second video is the sound produced when I apply fast pressure to the accelerator in order to move the car

Any advise would be welcome.

Just to provide an update, I took the car in for a service and they managed to find that the bracket on the exhaust was broken which LED to the sound.
