1 Hazard Flashing Warning Light Unit problem of the 2017 Toyota Corolla

Failure Date: 09/12/2017

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.

Headlamps on 1998 Toyota Corolla have fogged completely over. The fogging is on the external lens surface, not due to moisture on the inside of the headlamp assembly. Attempts to clean the surface ar temporary, with the fogging returning after a few days. The fogged lenses are a hazard as the light is greatly diminished over a clear lens.
