MAJOR ISSUE - MCU RESTARTING WHILE DRIVING

MAJOR ISSUE - MCU RESTARTING WHILE DRIVING

**reposting from my original reddit thread**

During my commute this morning my screen restarted at least 5 times. I’ve googled this issue and have seen model S have this issue but no one yet on model 3. I haven’t tried a hard reboot yet but will try. Will be calling customer support also.

Anybody else experience this?

UPDATE - firmware 2018.26.1

I called customer support and they checked the logs. They saw I updated to the current firmware recently and they noted down the event in which I described. They had me do a hard reset with brake pedal and also power off button within settings menu. I’ll update after my commute back home to see if the issue persists.

UPDATE #2 Sat in my car for an hour on my lunch break and issue is still persisting. Calling customer support again

UPDATE #3 Spoke to 3 diff reps each advising of the hard reboots. After some troubleshooting we ended up with a service appointment to get it looked at. I don’t know if they will be replacing the whole screen or if it’s a faulty temp sensor like what was suggested below but I’ll keep this thread updated. Also, the third rep said that this current firmware we’re on has been his least favorite and a few glitches have arisen based on his experience with other customers. He did say that another update should be rolling out soon within the next week. Hopefully that resolves my issue

UPDATE #4 Screen has completely turned off, I've tried to hard restart but no luck at all! This is super frustrating as I feel like I'm the only model 3 with this particular issue. My service appointment is in a week and there's nothing sooner. I know this is first world problem, but for the amount we pay for this vehicle there needs to be some sort of quality assurance =((((( Being that the MCU is our main and only visual for information (signaling, drive, reverse and park) this becomes an extreme safety issue!

Did you call them back and tell them you MCU is now dark and the car is unsafe to drive?

i have, yet they can't get me any sooner than next week.

Did they provide a loaner?

illestjar | July 27, 2018

i won't find out if they can get me a loaner until next weeks appointment

Did the AC shut off too?

wayne | July 27, 2018

Where are you located? Seems like you should get an emergency service appointment if the car is undrivable.

illestjar | July 27, 2018

I'm located in california, 2hrs from fremont. I emailed my delivery advisor to see if theres anything he can do on his end

illestjar | July 27, 2018

@lilbean the A/C stays on if i had it on while MCU was on

Bennettb619 | July 27, 2018

Does this mean that if something happens to my car I will be stuck at home with no way to get anywhere?

illestjar | July 27, 2018

@bennettb619 yea, thats my current situation, unless you're willing to drive without the MCU

lilbean | July 27, 2018

That's great @ilestjar. When mine went off on the X, so did the AC.

It's probably not great driving without the MCU, but if you run Waze on your phone at least you'll know how fast you're going. Agreed everything else is missing :-(

What was it Elon said about no binnacle? "You won't miss it"

illestjar, do you miss it? ;-)

Bennettb619 | July 27, 2018

I’m an 80 year old woman who does not like to drive. This sounds really scary and not safe.

Atoms | July 28, 2018

Probably needs the MCU replaced. Either that or the coad never loaded completely. These cars let you drive with partial code loading and the service advisor did not want me to drive off with the car and was going to give me a loaner. This is not safe and they should send out a mobile ranger to replace the MCU.

Use the Tesla app for speed info.

illestjar | July 28, 2018

@rxlawdude i can't connect to the car if the main computer keeps restarting

This one is a genuine "and so it continues" :)

KP in NPT | July 28, 2018

Yes, mos, because I bet if you go on BMW or GM or any other auto forum, no one else reports issues with their cars.

illestjar | July 29, 2018

this is true^
