Tesla Model S won't start problems

Filed Apr 18, 2024 · Electrical, Fuel system · TX

The component that Tesla has stated is the part that is failing is the MCU (Media Control Unit) which was a recalled part at one point but then Tesla decided to replace only a single part of the MCU which was the eMMC (embedded MultiMedia Card). Luckily the vehicle was not driving when it completely shut down and would not start back up but I was stuck in a restaurants drive-thru for roughly 4 hours till I could get a tow truck to come tow it. The tow truck had to put the car on dollies as the vehicle would not enter tow mode nor would it enter its emergency neutral mode so the vehicle could be moved. The windows would not go up or down and luckily the trunk was able to open because if not then I would have been stuck outside my vehicle as the door handles did not come out after I got out of it and closed the door behind me. Please read the messages from the tech as you will see that they tried to act as if they did not know what was going on with my vehicle but then i asked something else and they stated exactly what the issue was but supposedly could not confirm it was that unless they charged me a diagnosis fee and "got hands on" which I'm sure that info of what was wrong with my vehicle was nothing they needed to get their hands on. There were no warning lamps or messages UNTIL the vehicle shut off on me in the drive-thru and then the warnings started to populate staying that the vehicle was off, vehicle could not detect brake being pressed, and that the vehicle was not detecting the key. The repair estimate is no longer available in my app for some reason, probably because I did not repair the vehicle as they were wanting me to upgrade to the new MCU that is in the current vehicles and it would have been roughly $2,400.00. Just today, the vehicle would not start, would not move my seat or anything to its memorized position when I got in the vehicle and the screen was frozen, just as it did when the original recall happened of the MCU/eMMC, photo/videoattached.

-I think there is known problem with the Tesla. It autoaccelrates o behaves like someone is taking ove the control fo the car - The inital problem happend on June 24th 2022. I was in the parking lot of my work when It felt like I had lost control of the car to hit 2 parked cars. It cost severe damage to front of the car. Car was in the workshop for 4 months. This was completely unanticipated.I have hisotry of driving in US for over 20 years on major freeways before this without a single accident may have developed muscle memory( reflexes by repeated actions) in controlling the car. I was not distracted at the time. of note however my car had rear damages from being rear ended 10 days prior but Tesla authroized dealer had said it was drivable. The car was not in auto pilot mode - Tesla didnt give me any explanation and the repair workshop generalized saying it's usually driver's fault - Since the return from the repair I have 2 auto accelarations driving in the low speed zone. I had to break immediately to control it. Each time it felt like somthing remotely did this. There hasnt been recurrent damage. --The car was inspected by the Tesla authorized workshop couple of times and they claim nothing is wrong. -There have been no warning except on 04/15/2023 when it happened smewhere between 1.34 to 1.36 I thught I heard sort of noise/ quick warning. Again, each time it happens it feels like car is trying to do its own thing ( even when it's not in auto pilot mode)or someone is remotely doing it. Further info on my car: It was purchased in 2020 as a used from Tesla.This problem of auto accleartion or loss of control feeling did not start until car was rear ended in June 2022. I have security footage from the parking lot on how the car behaved in June of 2022 -

The Navigation system stops and doesn't start. Checking on Google, I see that this has happened to many Tesla Model S owners who have an older model. This is because of a chip store card that fails after 4-6 years. On a long drive, this doesn't take us to the next super charger. This can cause the car to stop suddenly when it runs out of charge, and create risk for drivers and for other vehicles on the road too. The navigation is important on Teslas to know that one can safely complete her journey without running out of charge.

On 11/25/2020, at approximately 12:00pm, while in line for the drive through car wash of a mobil gas station (los serranos country club dr), my vehicle, a white 2016 tesla model s, partially turned off. I could no longer steer the car nor could I restart the vehicle. The screens were completely black. I exited the vehicle and had to wait several minutes before I was able to get my vehicle restarted. This is not the first time something like this happened (though I cannot remember the exact dates of the previous incidents), where the vehicle would not start after stopping and I would not be able to steer the vehicle.

Apparently a total failure of the 'daughter board'. In this instance the car was parked when it happened. Got into car and at first wouldn't power up as normal. Touchscreen, including all controls for vehicle, would not start up. Climate started up but could not be controlled. Car would start but blinkers didn't not work. Something similar has happened on perhaps 10 or more occasions in the past, though usually could be fixed with a hard reset. In at least 2 instances the AC has stopped working midway through a drive (through over 100 degree weather with elderly persons in a very long drive- very unsafe)

While driving on a six lane highway, I received multiple alerts from the car saying that power was reduced, the vehicle was shutting down, service is required, pull over safely and vehicle may not restart. I pulled over into a parking lot to monitor the car, the alerts continued to come and go but the car remained on. I decided to drive the rest of the way home. I notified tesla service and received no response. The next day when I attempted to drive the car again, it would not start and there was a complete battery failure requiring battery replacement. There was no indication to me as the owner prior to this event that the battery was going to fail, however, access to my vehicle logs (which I cannot obtain from tesla) may have given me some indication. I was told battery failure was due to faulty seals on the rapid mate which allowed water intrusion and overcurrent within the battery.

The emmc is failing and causing the computer systems to act odd. I've reported it for the failing main screen and it turning off for over 36 hours but yesterday the speedometer screen went blank and wouldn't come on for a an extended period of time. The car wouldn't start at first, and when it did, there was no speedometer (!), no odometer, no battery level read out, no gear indicator, no headlights, nor any other function of the instrument panel. The vehicle was stationary when it failed. It flashed on for a second, which allowed lights to come on and go in drive, but it immediately turned back off leaving the car without any speedometer or other items listed above. This was in a neighborhood.

The main screen, mcu, on my tesla model s, 2015 70d began rebooting during driving. On saturday, july 4th, 2020, the car would not start at all. Tesla customer service coached me on getting the car to work without the main screen, however it is not safe. The brake lights, signal lights, rear camera do not work, verified by my spouse. Further, most of the other controls, e.g. De-fog, air conditioning, roof, etc, do not work. The re-booting of the screen, where it would blank out without warning, and eventually come back later, occurred while the car was in motion -- very distracting. At this point, the main display, or mcu, is "bricked" -- it won't display anything at all, so that has happened when the car is stationary.
