2012 Tesla Model S electrical system problems

“I tried to start the car and got the “Center Display unavailable” message. Reset the computer doesn’t help. I have to wait for more than 5 minutes for the system to be on.”

“I charge my Model S on a 30 amp circuit with the car location amperage set to 20 amps to avoid overheating the circuit. Around Sept 12 while plugged in to the 30 amp, the car pulled in 50 amps off the line causing a melting of the wires and a near fire based on the damages later found. The car is supposed to send charging error alerts or problems via the Tesla app. Instead it continued to try to pull power out of the burnt line for 11 days all the while further depleting the battery. I discovered my car a 0% battery range with a dead 12 volt as well just as it had depleted and discovered the burnt up wires. I charged the 12 volt and got the car to take a charge. The 20 amp charge setting upon starting the car had changed itself to 50 amps. I lowered the setting and began charging the car. I was then able to move my car to a faster 50 amp circuit because the 120 v 10 amp circuit was going to take 3-4 days to charge the car or longer. I plugged the car into the 50 amp circuit set at 40 amps and let the car charge. An update was then pushed to the car. After the update completed. I got a charging error message via the app. I went to the screen and checked my…”

“Both the 12 volt system and High voltage battery system or a component communicating between the two failed. I received a warning message that my vehicle may not restart and within 30 seconds it completely shutdown while driving in the middle of the road. The vehicle was essentially dead weight at this point. None of its features worked, the ability to unlock it, the ability to use electronic doors and windows functions could not be performed. it could not even be jumped to start the computer enabling it to be towed or put in neutral to even remove the vehicle from the roadway. The manufacturer has confirmed an inner fault within the High Voltage battery pack. I have since purchased and replaced this entire battery pack as it was said to be unserviceable.”

“The vehicle was not experiencing display or review view camera display issues but was out of caution serviced nuder Manufacturer Recall Number SB2121001 (NHTSA Recall Number 21V035) for no charge. The vehicle is not under warranty. There was no charge for the initial "repair". When the vehicle was returned, the rear view camera did not function (black screen and/or serious flicker when video was partially displayed). Also bubbles were introduced into the front display panel. On questioning the repair, I was strongly encouraged by technician and then by manager to get an updated "infotainment with an upgraded MCU" (which is unclear but perhaps a superset of the VCM and display components that are under recall), for a cost of $2000 and $500 for it to include FM radio (that I already have and always worked fine). The manager offered a deal for $1000 + $500 to include FM radio. An appointment was set up and the estimate for approval was $1500 for "infotainment upgrade" and $500 for "Radio upgrade", and $120 taxes for a total of $2120.00 I will cancel the upgrade and inquire again if the recall work is able to return the vehicle in working order without it needing a…”

“As the car drains the battery pretty quickly, I have turned on energy saving mode. In this mode the car enters a deeper sleep, consuming less power. Sometimes in this mode when starting the vehicle, the turn signals will not work (this appears to happen when the car sits for a while and the miles left on the battery is under 120 or so). After a quick stop (2 minutes out of the car), the turn signals will start working, and the driver display will show the blinking turn signal when they work, but it will not display when they do not work. Another issue is that after entering the car and "turning it on", by pressing the break, sometimes the driver display (which shows speed and current drive mode, PRND indicator) will be blank, not showing any information, despite the ability to operate the car, etc.”

“This is related to NHTSA recall 21V-035. Tesla replaced the 8Gb memory card with a 64Gb memory card (so I'm told) but the main car display screen still does not function most of the time. This results in; -unavailability of the rearview camera display -defrost/defog control settings unavailable for purposes of ensuring visibility -and exterior turn signal lighting may increase the risk of a crash I've had this to Tesla twice now but it has not been fixed.”
