Used 2018 Model 3 - MCU powering off several times consistently

[kenshimast]

So I just got a used Model 3 from a third party. It has really low miles (Less than 7k) and right off the bat the screen has powered off several times every trip and sometimes back to back, only staying alive for a few minutes.

I was able to get the software updated to the latest hoping that would fix it but it is still happening. I just unplugged the two usb ports for charging, hoping that will fix when I take it to work in the morning. I am not able to use the app yet until Tesla accepts the transfer.

Is this something that has been seen before? I've seen a few posts here and there but nothing showing that this is a common issue. Any help appreciated!

This is exactly why I hate private sales. Did you contact the seller about this issue? I'd start there.
A car this old with 7k miles has been sitting around A LOT.

Did someone put on a swivel mount on the screen?

Have a look at this

I will be today if it continues. Luckily they have a pretty solid warranty/return, so if no resolution quickly I might be returning it.

Hmmm, I am a bit confused. Why do you think the car has been sitting around a lot? I didn't see where the OP said what year it is.

Check the condition of the small 12V battery.

It likely has. It is a 2018. One owner in Colorado

Thank you all for the help and info! I dropped it off with Tesla this morning, they are going to give it a look over. I'll respond to this thread when a solution has been found.

2018 with 7k miles. Very suspicious.

2018 with 7k miles. Very suspicious.

Why is it very suspicious?

My 80+ year old parents had one of the first batch of Model 3's delivered in Vegas, theirs is a 2018 with only 10K miles currently. They never drove much to begin with, but moreso if you didn't drive much during COVID lockdowns, and since then if you're immunocompromised at that age.

Some people don't drive much, but want a nice car for when they do...

EDIT: My guess is OP's problem could be related to a dying 12V battery, my parents car was always well-behaved, then a year ago had all sorts of issues with not sleeping, features temporarily disabled, etc., and such until finally the 12V battery warning popped up as the root issue.

This message board was FULL of people who stayed home in 2020 with Teslas with dying 12V batteries. Our repeated advice is these cars don't like sitting down for indefinite periods of time.
