Two problems related to owners/service manual have been reported for the 2013 Tesla Model S. The most recently reported issues are listed below.
I don't recommend driving beyond the distance you can travel to and get back, I've seen a car that lost ability to charge to max, and actually limited to about 30% after mcu went black drive after a 30 second timeout no aeb (advanced emergency braking) no controlling suspension height no manual control of headlight lights no blinker sounds steering mode defaults to some setting (e. G. If I have it set to sport, during reboot of mcu is changes to standard or comfort, not sure but I can feel the steering wheel take less effort to turn than my normal sport mode) no hvac (heat, cool, vent) no defrosters no seat heaters no steering wheel heaters no radio/streaming no app connectivity to control the car no ability to see the car charge status from app trip a/b profiles user settings homelink bluetooth pairings no rear view camera metric areas may have speed shown in mph and not kph so be careful do to a few strange reported charging issues, be careful driving beyond the ability to get home without charging, (range) since I have seen a car that continued to get less max available range in capacity I have almost been in several accidents due to no defrost. I feel very unsafe when driving.
The mcu (main touchscreen computer) failed on my 2013 Tesla Model S around June 10th 2020, with ~45k miles. The mcu previously had some reboot issues but this time was different because the computer was constantly rebooting and wouldn't stop. This was after the car was left in the garage and not driven for about a week. I had Tesla replace the mcu on my car which cost ~$1700+. When the Tesla Model S mcu goes out, the car can still be driven but this computer is central to operating most functions of the car. Many vehicle functions no longer work with a failed mcu including the ac/heater; backup camera display; navigation instructions, gps, and maps; inside manual door locks and sunroof control; garage door opener; radio and all music play functionality; energy consumption displays; phone; vehicle charge settings and charge status display; selection of automatic personal positioning for steering wheel, seat, and mirror; many lighting controls; other vehicle settings; on-screen games; and more. There is a newer version of mcu that I pleaded with Tesla to obtain and install in my car but they said they couldn't get it. The mcu failures are apparently related to overused computer memory chips and the mcu replacement was actually a remanufactured computer and wasn't new. The replacement did have a new touchscreen and upgraded let modem but later had new 'low disk space' error messages and rebooted repeatedly within weeks of the mcu replacement.
