I was driving on interstate 435 w. in kansas city kansas. it was about 4:15 am traveling at 70-72 mph my visibility was ok but i thought that if i use my highbeam it would be better. as soon as i clicked high beam on my car instantly turned off. my headlights my interior lights and my radio powered off. as a panic reaction since i had zero visibility and it was dark outside my foot the brakes. as i remember my sibal had already tightened up before hitting the brakes but before i could realize it my car part powered back on by itself without me doing anything i look at my speedometer and i was going about 67-69. when my car powered on it seems as if it rezoned as if nothing had happened now i believe if i was in kansas city kansas rush-hour i would have caused a severe accident . even though it was maybe for a second or two that my car had powered off it was more that my car came to a complete stop and i believe with everything that was electrical they have power it off i don't believe that my brake lights would have worked as well. if that were the case i would've never have gave the driver behind me any kind of warning for them to be able to slow down. luckily it was 4 am in the morning with no traffic that i didn't cause any kind of accident because it would have been unknown how badly it would've cost if they were traffic. i'm not sure what caused this but i know as soon as i had exited off the the interstate i turn the car off turn it back on seem just fine when i went to go turn on the lights my car again powered off. i waited about 15 minutes before i started the car again and it started up just fine waiting for it to warm up turn my lights on again and it did nothing this time and i was able to resume home.
