2016 Tesla Model S lights complaints
Page 3 of 3: complaints 41 to 49 of 49, newest first, as owners wrote them.
My mcu failed which caused a series of safety issues. The backup camera no longer works. I can not control exterior lights. I cannot use the front or rear defroster which is problematic since the AC is stuck on the on position which causes condensation to form on the windshield, but without defrost control I cannot effectively clear the window. In additional all sounds are disabled which means safety systems such as turn signals and other warnings such as forward collision warning do not work nor can these systems be adjusted.
Center screen shut off while driving due to a 'mcu' failure (diagnosed by tesla service). I lost ability to control taillights, rearview camera, high beams, climate control, charging information, navigation, passenger airbag indicator. I was driving on a multi lane highway when it failed. Drivetrain, brakes and steering seem unaffected. At tesla service they tried to diagnose, and one of the resets disabled turn signals, which is a legal issue in addition to safety. The screen had rebooted several times on its own in the preceding weeks.
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.
The main touched which controls majority of car functions just randomly freezes. The car is drivable, but barely. Ac blows air at full blast but doesn't cool, signals don't work, lights are stuck either on or off. Etc. Can't lock the door. Defrost cannot be activated. So it's not trivial.
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.
After the shock (because of the failed autopilot), all the lights turned off and it was not possible to turn them on by using the which near the wheel. To turn them on, I had to reset the car from the central console. The dashcam footage is available here: https://www.dropbox.com/s/rjvy3ftoakx7j74/tesla_autopilot_and_lights_defects.mp4?dl=0
One of the lights does not turn on automatically or automatically turns off. A manual reset from the main control screen is needed to turn them on. The video footage is available here: https://www.dropbox.com/s/rnje8y4tc3grxg3/tesla_lights_bug.mp4?dl=0
Intermittent windshield wipers may fail. Has happened twice, video captured for second event. Headlights have turned off on three separate occasions while driving in dark. Most recent event was captured on dashcam, as well as iphone video, with multiple test scenarios (turning them from auto to on, and back again. Rebooting computer interface, etc). This is very dangerous, and could cause serious harm or death.
