Was driving my car home from work and about 5 minutes after I started it and began to drive, I went over a speed bump going 5mph and suddenly my theft alarm system starts going off and incessantly honking. My hazard lights also began to blink and my high beams turned on. I pulled over and pressed my Smart key alarm multiple times until the alarm stopped. Every time I would hit any sort of bump or use my turn signal switch, the alarm and headlights lights would start going off. I took it to Toyota and they can't figure out what's wrong. They said it is an electrical issue, but not a Toyota one. That doesn't make sense since Toyota engineers the electric components.
