I own a Toyota Vitz 2009 and am facing a unique problem.

The car loses acceleration at bumps and shifts automatically into neutral with no response from pedal but the engine keeps on running. The problem goes away once I switch off and restart the car.

I have changed gear oil, accelerator pedal, throttle body, and cleaned the catalytic converter. There are no codes.

Please guide me as I'm now thinking to sell the car due to this issue.
