My 2008 has been running fine. Recently bought. 80k miles. The only issue is that sometimes when I push the power button to turn the car off it resets. Like doesn't turn off but the dash lights up like it's in mx mode. Power light is steady orange. Pushing power again turns it off and everything is fine. It's almost like it electronically trips out momentarily. Suggestions?
I have no records showing how old the 12v in it is. I did the self diagnostic check and once the electric load of mx mode (acc-mode) is activated then volts go from 12.1 v (no load) to 11.5v in acc-mode. No lights or radio on.
