Two problems related to radio/tape cd player have been reported for the 2016 Tesla Model X. The most recently reported issues are listed below.
May 2020 while my car was still under warranty I continually had issues with the main screen. Issues were reported to Tesla who asserted it was the firmware. Tesla kept my car for over a week for repairs, then charged me $400 for new firmware. However within two months the issues began again, the screen going black and multiple errors. In August I was finally given another service appointment. This time they asserted it was the 12v battery (despite recently having that replaced in 2019). After replacing the 12v battery the problems with the mcu still persisted. It takes about 3wks to 1month to even get a service appointment. Now they are saying the issue is with the mcu which needs to be replaced. I do believe the issue was with the mcu all the time. I do believe Tesla either misdiagnosed or knowingly did not resolve the issue. Now I am being asked to pay $2500 not including tax and labor to replace the entire mcu for problems which were initially reported while the car was under warranty. Further, Tesla is now claiming they no longer have logs of diagnostics on my car when I requested to see the diagnostics that were previously run diagnosing my black screen althout the do agree my car has been continually brought in for a black screen and non-functioning system. Disabled screen functionality causes several other systems of the car not to work: regenerative braking disabled, autopilot disabled, driver and user settings, disabled, ac unit not functioning, stereo/radio capability disabled. Each day a different alarm or not would come on disabling another function while driving. Very dangerous and very unnerving, especially while transporting three young children. I have asked Tesla for diagnostics logs on my car and hoping to receive and submit them as support for this complaint.
Mcu (media control unit) failed on multiple occasions, I was unable to control ac/radio/autopilot system/ or navigation. Also both turn signal were in-operational. Tesla service center refuses to replace the mcu or fix it. Vehicle was in motion, on highway at a speed of about 70 mph.
