    My Prius V, 2913, has 155,000 miles. Recently, while I was stopped, when the gas engine started itself, a severe knocking occurred.

    The knocking seemed to happened by the transmission, or the electric engine. From then on, the knocking happens only when the gas engine starts itself. Most of the times it last for about 4 seconds, being stopped or when taking off, then it disappears.

    Has anyone gone through this problem..? I'll appreciate valuable advice.

    What is the engine oil level?
    When was the oil last changed?
    What viscosity are you using?
