2010 Toyota Prius Hazard lights came on without button being pushed and won't shut off even when car is off.

Asked by Mar 29, 2015 at 02:33 PM about the 2010 Toyota Prius

Question type: Maintenance & Repair

Was driving with no issues. Hazard lights started flashing on their own and then several
other warning lights came on. Stopped and checked fuses and removed the hazard
light fuse to get home without the lights continuing to flash.  Found penny in the aux.
'cigarette lighter' style port inside center armrest - may have caused a short.  Tried
disconnecting aux. battery in back of car and then reconnecting and starting.  No
change.  Hazard lights still flashing whether car is on or off. If there was a short-circut  
is there something that needs to be done to reboot the warning light system and the
hazard lights?

Have you checked the hazard light switch? Mine had a short and I replaced it. Problem solved
