Two problems related to fog light switch have been reported for the 2016 Tesla Model S. The most recently reported issues are listed below.
My media control unit (mcu) has failed and Tesla is slow to provide me a replacement. They claim that I will be provided a "refurbished unit" as soon as one becomes available. The mcu failure has impacted my cars rear backup camera, the charging system, the ability to turn on/off headlights and fogs lights, driver settings such as steering (ride selection), front crash warnings, etc. My turn signals are not responding either, and I'm gravely concerned about other safety features failing without this component being replaced. Tesla acts like it's main purpose is for media like navigation, music, etc. But as I stated, several items are direct safety hazards. Tesla knew of this mcu problem long ago and should have issued a recall for all Tesla Model S owners experiencing this problem.
I've been having ongoing issues with the mcu/ touch screen. I was driving early morning one day when it was still dark outside. I went to turn on fog lights and all of a sudden the headlights turned off and the touch screen froze on me. I had no way of turning the headlights back on and had to drive in the dark without knowing what is ahead of me until I stopped on the side of the road. They did replace the mcu, however I've still been having issues with the touch screen. I don't have full confidence in the system. How do I know this won't happen again?.
