So this morning I went out and when I got home turned car off and took the key out and the radio stayed on.so tried to shut off with no key and would not go off. Turned car on and the radio then would go off. So my problem is the radio stays on when shutting car off even with key out. Strange. Any suggestions?

 

I assume no one has had this experience with there car. Going to take it to Lexus for the first time. Can not imagine the cost.but must be done. If I had to take a guess I would it is in the ignition system. We will see.

 

Sounds like a relay is not shutting off when the ignition is switched off.
Maybe someone who has a wiring diagram can point you to the relevant relay.

 

I have no idea, but if it were me, I would find all fuses or relays that relate to the radio and start checking them out. I've gotten lucky going this route on other issues. Sometimes just jiggling them has helped start a car that wouldn't start. Nothing surprises me with electrical issues.
