Five problems related to radio/tape cd player have been reported for the 2013 Tesla Model S. The most recently reported issues are listed below.
I have had multiple issues with my 2013 Model S including but not limited to total failure of the mcu, total failure of the battery and partial failure of the tire pressure monitoring system. Some problems that I have encountered during the mcu failure before and after the mcu was replaced include loss of ability to access the screen to turn on heat, radio, defrosters, bluetooth, or any other function of the screen that is available, loss of blinker sound, loss of parking chime sound, loss of sound from the stereo including no bluetooth or music. While driving from blaine, mn to st. Paul, mn with my blinker on the majority of the time on the freeway with out my knowledge because the was no blinker sound. That was not only frightening but also dangerous. I have had a myriad of issues with this vehicle and I am really fearful of a total failure while I am driving. All of the issues noted above were during motion. One other problem I have noticed is my car takes an excessive amount of time to turn on.
The car was pending an over the air update which I was delaying because of the research I found online about the computer touchscreen chip going out. The update was forced to the car while it was in my garage and after the update the touchscreen was non functional. Because of this most features were not usable like a/c and radio. The more important features that were not able to use were that the turn signal.
Mcu has been malfunctioning. Without it I cannot control climate, backup camera, radio, turn signals, charging, navigation, and a number of other important features. This problem has been ongoing and intermittent, but recently has become more common.
Tesla released an update that throttled how fast my car DC charges and reduced my range. I used to be able to start DC charging at 99kw and now it starts at 72kw and taper from there. Also I can't charge to 100% now. It stops around 97% and say "calculating remaining time" and after 30-40 minutes stops and says charging complete. My maximum rated range is now 167 miles down from 208 miles. That's a 20%, 40 mile loss of range. I had Tesla look at it twice and they say nothing is wrong. Last appt they sent me a text on Feb 10th and cancelled my appt saying there's no issue. Now in the winter I can't make it home to toledo OH from columbus OH a 132 mile trip. Real world in the cold you lose 25% range to keeping the battery warm. With Tesla capping my range with the update plus the range loss in winter I'm short 10 miles.
The center media touchscreen (mcu) in my vehicle stopped functioning and several functions ceased working. Initially I received a "touchscreen unresponsive" message while driving so when I stopped at a stoplight I attempted to reboot the mcu using the steering wheel controls. The screen started the reboot process but everything that was on including hvac and radio turned off for the remainder of my drive and were inoperable until after the screen was replaced. The touchscreen never turned back on. Many functions did not work when the mcu died with the oddest one of all being that I had no turn signal sounds which I think are created by the cars audio system and the mcu. With the loss of the mcu, I lost the use of my backup camera and my hvac which was stuck in an off state so I had to roll down my windows in order to have any airflow in the cabin. Thankfully I did not need the forward or rear defroster between when my screen stopped working and it was replaced as both are controlled via the mcu and were unavailable. Charging at home was extremely limited and maxed out at very low amperage and I was unable to change the charging amperage due to the inaccessible touchscreen. I did not try a DC fast charger. Mobile app control was unavailable so I was not able to use it to adjust my hvac or charging settings. The controls for adjusting the active air suspension were also not available however the car appeared to set itself to a normal ride height. No steering wheel controls (hvac, radio, sunroof, voice commands) worked and my headlights were stuck in auto mode that was the second mcu in my car, previously being replaced about 14 months earlier due to the screen adhesive failing which caused air bubbles to form within the touchscreen. I think the cause of the mcu failure was emmc flash reaching its maximum write lifetime despite the prior replacement.
