Five problems related to headlights have been reported for the 2016 Tesla Model S. The most recently reported issues are listed below.
Center screen (mcu) often fails so that I cannot access the backup camera, headlight controls, and many other critical functions.
VIN: [xxx] while driving air suspension has wildly activated. Unable to manually turn headlights on at night. Entertainment system has, uncommandedly, activated on full volume and unable to reduce/mute. Bluetooth link disconnected from phone eliminating handsfree ability mid-call. Mcu (media control unit)/mainscreen has rebooted on its own, with high outside heat, phoenix, arizona< shutting off cabin cooling for as long as 5 minutes. These are primary safety concerns and major distractions. Additionally, there is frequent loss of gps/navigation position, false aural warnings and sometimes a completely unresponsive mcu that a reset sometimes/temporarily clears. This has happened since the summer through now both locally within the phoenix, arizona area, parts of northern arizona, nevada and California at different times, elevations, climates and time of day. I have video that I can share with you if needed. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The center screen (infotainment center) went blank on me and I could not control main features. I couldn't control my sunroof which was left open to vent. I couldn't use my rear view camera. All sensors were not working. The air conditioning and heater was my working and I could not control them. Defroster and radio were not working as well. I could not control the headlights and certain driving modes.
Drl burn out repeatedly. This is a common issue for 2016-2020 Model S headlights. Headlights need to be replaced for the second time in just 50k miles.
In September of 2018 I noticed one of the daytime running lights started to go out. I took the car to Tesla and they replaced the headlight. Shortly after the other side did the same thing. Again they replaced the headlight. Then in June of 2019 one of the daytime running lights went out again. It was replaced again. Now I am out of warranty and both daytime running lights are going out again. There is some defect that causes them to burn out. I felt it was a safety issue because the daytime running lights are supposed to decrease accidents.
