Hi all, first, I apologize if I failed to search existing threads and find all this info already. I did go pretty deep in the eMMC wiki sticky, which was very helpful. But it didn’t answer all my questions.
I have a 2013 Model S 60kwh with about 54,000 miles on it. I did not have the eMMC issue on my radar at all until one of the most recent updates. I wrote to Tesla Service right after a software update because the car became glitchy right after the update. I just wanted to alert them I was experiencing issues and hoping to put in a bug report. They immediately set me up for the MCU replacement (out of warranty, of course).
After doing some research, I recognize these symptoms from the wiki thread:
1) stuttering AM/FM on occasion in first 15 seconds of startup - this may have started months or even years ago, but this was the only symptom I had and never regarded it as an issue;
2) restarting the MCU daily — this only started after most recent software update (so only a couple of months ago)
However, my car has other glitches that I have not seen described in the threads:
3) while parked, and whether or not charging or not charging, the car “wakes” up frequently and cycles and makers whirring noises, etc. NOTE: I recently needed my 12volt battery changed, but the part was backordered for months, I thought alot of these issues were related to the 12volt battery having died and relying on the lithium-ion battery. I have a video that I took (just for the sound), but now sure if it will upload...
4) range seems to have gone down a lot, but I think that is because the car is using a ton of electricity while being idle
5) related to above, we went out of town in early August, Tesla stayed behind, left the car plugged in. It charged to approx 80% but now the charging has stopped and won’t restart and from 170 miles of approx range, the app now says I have 70 miles of range. So in 3 weeks the car has used 30-35 khw of electricity sitting in a garage — is this related to MCU failure???
6) several years ago I paid the $500 upgrade to go from 3G to 4G — I immediately complained and said that nothing seemed faster to me. The SC just gaslighted me on that and I let it drop — was that because I was on MCU1 and was never going to see a speed increase or was I already in MCU failure then?
Lastly, just to reiterate the question partially mentioned above — would not being able to replace the 12 volt battery for a long time cause additional eMMC cycles or get it into a cycle loop or otherwise trigger a series of other issues? I literally had to wait 3 to 4 months to get a new 12 volt battery from Tesla.
