Headlight Switch problems of the 2006 Chrysler 300

I was driving the car and the headlights shut off, dash lights went out and warning lights on the dash started lighting up and blinking on the dash. In addition, the gauges all dropped to zero and then returned after a few seconds. Everything returned to normal after a few seconds except the headlights. The headlights returned when switched to on instead of auto (it was dark outside). This all happened while the car was in motion at 60mph. After the car was parked and engine shut down, I restarted it and the headlights worked properly in the auto setting again. This problem replicated itself 2 weeks after the first incident. Again, headlights shut off while driving in the dark.

Tl- the contact owns a 2006 Chrysler 300. The contact stated whenever driving various speeds at night the headlights would illuminate intermittently. The vehicle was taken to an independent mechanic on three occasions. The dimmer switch was replaced and the failure persisted after the vehicle was repaired. The technician was unable to locate or duplicate the failure. The manufacturer was notified of the defect. The approximate failure mileage was 96,000. Rvk.
