    I received these codes (Code P0A94 & P0A7A) after putting my car in power mode and flooring the pedal twice. It immediately gave me those codes. The car was drivable but seems to lack some power and when I hit the gas there seems to be a noise under the vehicle. Not sure what the issue can be?

    The trouble codes point to a possible problem with the inverter. Toyota has an extended warranty for the inverter. Do NOT clear the trouble codes. Take your car (or have it towed) to a Toyota dealership for diagnostics. If they determine that it is covered by the extended warranty, all repairs will be free.

    Unfortunately, I have already tried clearing the codes to see if the check hybrid system warning light would go away. It did not. When revving up in power mode it feels like something disengaged because the power mode light does not turn on and when I give it gas it seems like something is loose under my car.
