Light acceleration from standing resonance vibration coming through gas pedal ,seat and floor Nothing if in EV drive. Roughness in engine sound also Goes away if you lift off the accelerator,comes on again if repeating acceleration at speed

Default RX400h pedal vibration

Took 18 month. Lexus uk put it down to a characteristic and wouldn’t move. Point is they did not know. As I said 18 month later I got a fault Code to say the hybrid pump was faulty. Changed this pump and vibration dissapeared. Good luck

Do you recall, was it the hybrid coolant pump? Also did you happen to get codes from your paperwork?
