I'm having an intermittent issue where all systems will fail, the instrument cluster, command system, windows, turn signals, etc. The car will drive fine otherwise and then everything will reboot and return to normal. I was able to access the blind spot sensors ( I read a possible culprit) but they were not badly corroded and with the sensors unplugged the problem still occurred. Something is shorting out the systems. The local dealer and couple local import shops don't have a "smoking gun" and want to spend several hours to diagnose. Any suggestions on where to start and have repair shop focus?
