For whatever reason during random trips I’ll notice my info system on my gauge cluster will start flickering and after a few minutes it will crash/reboot both the cluster and stereo system.

Today, it got to the point on my drive where it unlocked/relocked my doors and revved my RPMs all the way up, as if I had turned the car on/off.

Any ideas on what could be causing this?

 

Battery connections and battery condition is step one. Loose connections or a weak battery will cause all kinds of crazy stuff.
