2021.24.28 Rolling out to MCU1/FSD MS/X

2017 MS with MCU1/FSD

First significant firmware update in over a year!

Old firmware 2020.48.37.8 (0.6% of TeslaFi Fleet AWT upgrade)
New firmware 2021.24.28 (0.4% of TeslaFi Fleet running this version)

Guessing no FSD Beta access but I'm 6 months closer than 2020.48. Lol.

Installed the update on 2016 MX. The startup is faster. Emmc recall fix scheduled on the 23rd. Debating whether to go for the mcu2 now or later.

Alert after declining installation several times advised AT&T won’t work after 2/22 without this update.

Do you still have 3G? I know that was ending soon.

Confirmed that the Dashcam improvements did not solve the issue of all FSD/HW3+MCU1 cars recording broken video.

With this update, my instrument panel has started crashing during the drive. I have only driven a handful of miles, but already twice during a drive instrument panel has gone black. After a few seconds a Tesla logo appears and it starts to work again.

While outages are quite short, not showing car speed while driving is a safety issue. Also it is very distracting.

I do not recall ever seeing this issue before the latest software update.

After the update, I cannot get the Superchargers to show on the map unless I want a whole list of them displayed in a navigation menu box as well. Is there some way to leave the Supercharger pins (with available stall numbers displayed as before) while removing the navigation menu box?

please be sure to come back and update your experience. The one post about the improved UI is a one-off if you read all the posts

Make it 2 posts. My browser has not worked this well since 2018. Even then I didn't use it as it was too slow. I have checked it every so often, about 6 times over the past 3 years after an update just to check it. Every time after about 30 seconds of waiting for a page to load I gave up. I have even factory reset the car last year to try to speed things up, and tried the other tricks like putting up the drawing page, and it still was half the speed of dial-up.

Yesterday I drove around using Teslawaze for the first time, and it worked. It searched in a few seconds, and after clicking it only took about 5 seconds to load the page on the touchscreen. Don't know if I will become a Teslawaze regular, or even use the browser, as I really don't care; I'll use the phone (when not driving of course). But I have read of many who love Teslawaze.

The release notes took about 30 seconds to show for me too, don't know why that takes longer than pulling up a webpage, but that is what is happening on my car.

Has anyone going in for MCU replacement or repair gotten the cameras replaced??

No, LTE

Wish I had not done the update. Now all streaming stations don’t work on LTE. They jus constantly buffer.

Glad to see I'm not the only one that was running 2020 software in 2022. I'm downloading 2021.24.28 now. Even if it isn't a significant update I'm glad to finally get an update. I paid for FSD when I bought the car and will not be paying for more hardware. Tesla tried to get me to purchase MCU2 when they replaced the eMMC.

FWIW- this update 2021.24.28 may have fixed an issue I've been having since before the eMMc memory failed- MCU lock ups when in Camp Mode. The MCU was crashing every time we entered Camp Mode with the HVAC- it crashed at exactly the time the "campfire scene" was supposed to appear. This has been driving me nuts for months- Service just told me to upgrade to MCU2 or live with it. as they were not going to fix it. Well, for the first time in over a year, I finally got to use Camp mode - Funny we have more than one AP1 Model S and only one of them had this issue - Hopefully, this fixes it for good. Now if the random AP errors go away- It will be livable to not upgrade to MCU2. Since we use SirrusXM- that is a 2K expense I wasn't looking forward to.

I have not done the update and I’m having that issue today as well.

Thanks for sharing. I’ll report back tomorrow if it improves

The supercharger stations are partially hidden after this update. Not as blatant as V11, but it’s annoying (for me) that sometimes they show and sometimes they don’t based on zoom level, navigating status, etc. I prefer just having them on the map all the time

Having a similar problem with podcasts.

Having a similar problem with podcasts.

Have you tried to restart the system by pressing both the scroll wheels on the steering?

I tried to navigate to Disneyland from the Bay Area and it was showing no route available. lol I'm going to drop off the car for MCU2 upgrade in the morning but want to give it one last shot. Oh well....

 

[VegarHenriksen]

Does this allow preconditioning under 20% SOC?

 

[sonofagunn]

I'm also experiencing buffering of streaming music since this update.
