Is model S safe to drive with dead MCU?

[polyphase]

My 2013 model S has been garaged and plugged in for a month. It went into deep sleep (I assume) Upon my return I got the car to slowly boot up systems but the center console isn't coming on. The car will go into gear and out. The dashboard screen seems to be working properly (but nothing dependent on the MCU) works. The glove box door opened but it won't shut. The charging cable disengages and reengages. The dashboard indicates it is charging.

Is the car safe to drive? Thanks.

You should be fine, so long as you can still charge consistently. The AC controls, etc. won’t work, but everything required to drive safely is independent of MCU.

you're going to want to read through this. With my car, I couldn't charge and my turn signals didn't work.

I think a lot of people are not realizing their MCU has died during this lockdown since they have not been in their car. Tesla has also been aggressive in pushing updates since they are retiring all the old versions May 1st.

Can you be more specific on what that means (or a link explaining it).

Reads and writes wear on the flash memory. Tesla pushing updates might push some folk's already dying flash memory over the edge.

Are you sure the signals themselves didn’t work? I know the clicking noise stops.

Well I'll let you read it from the source

Tony was investigating this; he was thinking if the battery is disconnected this happens. Don't know if he confirmed or not.

Why Is Tesla Forcing Software Updates If No Safety Issue Is Involved?

Can verify. Signals themselves do not come on. I lost signal noises while my MCU was dying but not black. Once black lost AP, signals themselves and a lot more but brake light works including Regen triggered. No signals must use hand signs like an antique. As I said earlier, a real hassle.

I guess a rebooting MCU works differently then.

False alarm. The MCU did not die. The car was in deep sleep and while the drive electronics booted up after 3 or 4 minutes, the MCU remained dead for at least 10 minutes, when I got tired of waiting and left. Some time after that I saw the phone app re-established a connection with the car and this morning when I went back out, all was well. Thank you for all your replies.

Shakespeare got it right then: “All’s well that ends well”. Nice ending!

Possible sign of impending death. That's what happened to mine a few times before it died off.

That's just great... I was assuming my turn signals were working. NHTSA really needs to force a recall for this problem.

Look carefully at your avatar on the IC and you'll see whether blinkers are actually turning on. Obviously you'll hear the initial click when you push the turn signal stalk either direction but nothing further and you can see no turn signal indicators on IC (green blinking arrow) and nothing on car Avatar.

It was a few months ago so I don't remember exactly. I do remember sometimes it would click and sometime sit wouldn't.... Anyways, still, it's a cause of concern. Glad you guys brought this up for owners who experience this failure in the future.

Time to change the "Model S" badge to "Model T"
