2011 LS460, 42K miles, garage kept.
Any ideas.
The radio volume ****. Noticed had to push in to power on a couple times before it would turn on. Then hard time to increase the volume. A full turn of the **** to go up from 40 to 42.
Then I kept turning and would not go up more. Then decided to turn off. And turn back on.
Then the volume numbers started to go up by itself to max. And I could not turn the volume down. And took a couple tries to even turn it off.
For the first time it has been parked outside in the heat for about a week without use. Could the heat have something to do with it?
Any idea of the price if I do have to replace?
Thanks for any ideas. Never had a problem before.
