My 2013 GS350's dashboard clock has started to run 30+ mins faster. I can fix the time in the evening and the following morning is 30+ mins faster.. This has been going on for 4 days now. Clock was accurate before that time. Weather has been reasonable (30-60F) so no extreme temperatures to affect voltage. Battery is about 4yrs old. I don't have a problem cranking up in the morning.
Any thoughts?
