Likely MCU Failure (MCU1 eMMC)

I had my screen go dark last week and drove my 2015 S 85 up to Portland, OR service center. I've been getting regular text message updates on the progress. They are replacing with a factory refurbished MCU1. They are also replacing the rear main drive unit which was making a whining noise, some resistance modules and a cooling fan system. I bought the car in May with 50,000 miles through the Tesla CPO, so it came with a 2-year additional warranty. I'd hate to have to pay for all of this myself.

I still have a few more miles and months left on my original warranty and because I own a first generation Model X, I think the likelihood of something going wrong is pretty high so I will probably get the extended warranty before the 4 years are up.
 
Interesting news... Elon Musk: Tesla MCU computer upgrade going to be $2,000, but don't recommend it - Electrek

Looks like @elonmusk followed through, and excess logging to the eMMC has been significantly curtailed in recent versions. Should extend life a bit on MCU1.
Bit (like, years) late for many vehicles, unfortunately. Many will still need repair eventually.

Should be much better at this point

Uh-oh, I may be the next victim of this (2014 pre-AP S60 ~146,000 km). I started following Tesla in 2015 and thought I had covered all of the bases. I didn't appreciate the gravity of this issue until I saw Rich Rebuild's video about it shortly after getting my car 4 months ago (I watched most of his other videos; don't know how I missed this one!).

Because I'm a new owner, I just figured connectivity drops, loading errors and similar were normal for a 5 year old car. It isn't like I noticed a change in the vehicle's behaviour.

Anyway, I went to unlock it with the app yesterday morning and the app thought it worked properly, but the handles wouldn't present. I popped the frunk and it displayed as open in the app, but the frunk didn't open. I tried a reboot unsuccessfully so decided to leave it as it was charging at the time and I wanted to let it finish in case this would be the last charge it allows.

Today I took the charge cable out and put it into drive (still drives), then put it in P and rebooted. I got the Tesla T back up on the main screen, but it never booted. Service appointment next week. Fingers crossed that I'm not up for a $3k surprise.

Either way, it will be an interesting week driving around without heat in the Canadian winter :). At least the wipers still work. Man, I'm going to have to use a scraper?!

FWIW, I got quoted $2k not $3k for MCU1 replacement last month. Don’t accept $3k.

Right... third party repair cost is less and Tony is a provider.

cost from Tesla I was quoted is $2k US. Earlier in this saga, I’m pretty sure they were quoting $3k.

personally I’m waiting til my extended warranty runs out or they offer the $2k MCU2 upgrade that Musk tweeted about.

Zax can also help, he's in Canada. Taxes and shipping makes it not as good to offer my services over the boarder.

I was able to drive it just fine tonight. I dressed warm so I could keep the windows open so I didn’t fog up at -10 C. Worked fine, but I don’t think I’ll be doing any road trips with the whole family in there until we get some heat.

One curiosity is that the speedometer was reading about 40% low. Mine is pre-AP so my blue ‘analog’ indicator was correct reading 65km/h, but the number was only reading 40km/h. When I set the (basic) cruise, the bug went to 40km/h and it maintained 65km/h actual.

Things that worked: wipers, lights, windows, opening the charge port and frunk with the fob, indicators and sounds (though the sounds only came back after an unsuccessful reboot).
