Hello, I have a ES350 2010 and the electronica system seems to be having problems, such as the mirrors sometimes rotate down when the in revers sometimes they don't. Sometimes the rear shade will retract, sometimes it won't. The door locks will sometimes respond and sometimes they won't, and sometimes, when playing music in the radio, the music sounds "wobbly", like the voltage is varying (difficult to explain). Sometimes the seat cooler starts even though the system is off. All of this happens randomly. Any idea as to what could be the culprit will be very much appreciated.

 

How old is your battery

 

Good point. I'll replace the battery and report back. Thank you.

 

Don't throw money at it just have the battery checked and if necessary replace.
