    How many miles on the odometer?

    1. Check oil level.
    2. Check muffler condition.
    3. Test 12 volt battery health.
    4. Check hybrid battery ventilation fan is clean.

    Might also be Exhaust Gas Recirculation circuit clogging? This goes all the way from the exhaust manifold to the intake manifold. The main components are along the right side of the engine.

    If this all started after the oil change.......then that's where you need to investigate. Is there too much oil?

    Toyota has issued a free extended warranty on the EGR valve. A defective valve can cause these symptoms.

    sounds like hybrid battery issue... Do you have pets in your car? check your hybrid fan and see if its causing an overheat or some sort... any check engine light? hows your battery charging? is it full bars or 2 bars? when have you noticed this started happening? any major damage? did you bought it new or used?
