What can fail
A bolt in the hybrid inverter assembly may not be properly tightened. If it loosens, the vehicle could lose power to the wheels or enter reduced power mode. A loose bolt could also cause a short circuit when the ignition is on.
What the fix does
A dealer will inspect the inverter assembly bolt and tighten it or replace the entire inverter assembly if needed.
