What codes are you getting?

PDC issue sounds like one or more is reporting a "hey I'm stuck" mode which shuts down the PDC after a long solid tone at startup. Water infiltration is possible...

Thermostat is probably stuck in the open position.

Power steering hose leak... Ugh, finding replacement one, but a farm store that makes hoses for tractors is a good HD replacement .[emoji106]

Key issue could be antenna problem or the immobilizer box underneath the steering column on the firewall. (SWAG)
