I took my car to the Lexus dealer after a basic routine maintenance and a warning light came on with the description "Check Hybrid System". It was the only light on.
I let them know of the problem They ran a diagnostic on it, the car came back with trouble code: P0705, they told me that the transmission control module needed to be replaced; parts, labor, and tax would cost $1300. Note: They did not replace the part yet.
They told me that it was an intermittent fault and that if happens again that they will need my car for a few days to run some tests.
I'm not sure that the transmission fault is causing the Hybrid light to come on, could I be wrong?

Hello,
Most hybrid drive systems use a motor housed in the transmission. So, yes, the transmission fault can trigger hybrid drive warnings.
