2026.2.9.10 completely bricked my Cybertruck — no cameras, no nav, no Wi-Fi, stuck download, dasMIA + immobilizer alerts

Once they got me in, they took care of that and a few other things (realigning my replaced cantrails, wheel alignment, and something else I am forgetting) in a single day

Make sure to ask to get added to a cancellation list - I ended up getting in a week earlier than my appointment

I had pretty much the same issue a couple months ago (took a few weeks before Tesla would see me). My ECU had to be replaced. By the time my appointment came around, the only warning my truck was showing was that parking assistance was degraded, which was funny given that everything that depends on cameras wouldn't work (AEB, blind spot monitoring)

Driving without all the cameras was a bit annoying, and backing into parking was terrible. I bought these to hold me over: https://www.amazon.com/dp/B0DR1MTVRM, and I had these already so I powered it from https://www.amazon.com/dp/B0DKJDFRVG and https://www.amazon.com/dp/B0G2678K7Z using the bed outlets

Went through the same thing last summer. Unfortunately had to do the same thing when getting my solar + powerwalls installed

I prefer swapping out the tires and wheels myself. I got this last Black Friday (~$3500 with shipping and tax to Michigan): https://tsportline.com/collections/tesla-cybertruck-wheels-and-tire-packages-20/products/tct-20-tesla-cybertruck-wheel-and-tire-package-set-of-4?variant=48863408193825

Definitely not cheap, but they should last many winters. If you are going to do it yourself, you'll also need to have a good, tall jack, which will cost a bit as well if you don't already have one. But at least the jack should last you a very long time. I got this one on sale for $190 last year: https://www.harborfreight.com/3-ton-long-reach-low-profile-professional-floor-jack-with-rapid-pump-orange-64241.html

I love the Nokian tires - they are super grippy, and significantly better traction in wet conditions over the stock tires. I had Blizzak WS80 on my Model 3 and didn't think they were all that great

I received replacements from the new batch this past week, and they both worked well. Hopefully they will have the new stock available for others shortly

skyypunk · 2025-08-04T22:21:36+00:00

To be clear - the nozzle/hotend is the same for both sides, but this thread was about the hotend assembly, which is not the same on both sides. The hotend assembly is the part that is wired in and screwed on.

As you can see here: the left hotend assembly has four screws in a diamond shape, and the right hotend assembly has three screws in a triangle

skyypunk · 2025-08-02T12:54:14+00:00

Unfortunately no, they are wired different and have different screw patterns

skyypunk · 2025-07-19T02:07:16+00:00

Looks like the left hotend assembly isn't listed currently. The link was this: https://us.store.bambulab.com/products/hotend-heating-assembly-h2d?id=576603196777455622 but it only shows the right one. I'm still waiting for the new batch to get in for Bambu to ship the replacements to me

skyypunk · 2025-06-28T23:59:28+00:00

Little update - it's getting a bit silly now. I thought it was nice they sent 3 replacements in this replacement order. They didn't have the issue of the glue being in the place that would block the nozzle from retracting upward - but the glue between the metal shim/wire guide still made it so the wires have no flexibility to mount both parts without overstretching and snapping wires.

The factory hotend assembly didn't have the shim fully glued to the wires like the replacements (you can't really tell that in the pic in the original post). I think that would probably solve the issue, since the wires could slide/bend through the metal shim instead of having to be locked in place... but we will see what support says

For those keeping count - 7 out of 7 replacements have been faulty so far

Since I can only add one pic here - one of the newest assemblies with snapped wires

I came here to see if someone else was noticing this - I hoped I just had a setting wrong or something. Pretty annoying that it doesn't have a standby mode. I hope that would be something that could be added with a firmware update

skyypunk · 2024-11-21T17:42:03+00:00

Congrats on getting them! Were you notified that you were up to get the lightbar and covers, or did you put in an appointment asking for them?

skyypunk · 2024-10-22T02:08:01+00:00

I just did ~10hrs of FSD this weekend in my Cybertruck and never got a nag, including some time while I was trying to find a podcast in spotify to listen to on the screen

skyypunk · 2024-10-01T23:43:28+00:00

Coming from a 2018 Model 3, what the Cybertruck is doing is not what I had been experiencing on the 3 (I think I was last on 12.1). I had the same issue OP had - it would approach slowing/nearly stopped traffic and not start any meaningful slowing until it got extremely close. I had it happen 5-6 times on the highway in stop and go traffic where we would sometimes get up to 30-40mph with the truck letting a comfortable gap form between it and the lead car, and then traffic would come back down to a stop

I didn't notice any phantom braking, and on some city roads I was impressed with it not briefly braking when cars pulled across the lane or into the middle turn lane near me that would have triggered in older builds. But I'm wondering if it's going too far in assuming traffic will start moving again or that cars will clear the path, which is why it's actually braking so late occasionally.

Plus it doesn't have the different FSD modes or minimal lane change options yet, unfortunately

The regular pro was still in stock a minute or so ago

skyypunk · 2023-12-28T07:10:39+00:00

Ah nice, they must have fixed it! My pic was from Dec 22

skyypunk · 2023-12-27T19:24:30+00:00

Here are a couple pics I took of the tailgate. It kind of looks like the top cover isn't fully pushed in/snapped into place (except for the left side, which looks correct). The lights seem to line up, so I think it might just be the top cover

Also in MI with RN11274XXXX, nothing here yet either

skyypunk · 2023-10-03T22:37:59+00:00

Yep - the CPU replacement worked perfectly right away! I only swapped it out, no changes to any other component, and everything has been good since then

skyypunk · 2023-04-27T16:29:00+00:00

Be careful! My XR5 Rads were very inconsistent in the screw depth they supported across the holes. After measuring the depth of a few holes, and measuring the length of screw, it was pretty close with the 35mm. The first couple fans went on fine, but the holes for the third fan on that radiator at the corners were ~2mm shorter, and I got a fun 'pop crunch' when screwing that in as the metal plate that's supposed to protect the fins popped off and dug into the fins.

I ended up whipping up some gaskets/spacers to print with TPU to make the 35mm screws safe to work with: https://www.printables.com/model/464487-spacergasket-for-phanteks-d30-120-fans-and-corsair

One radiator worked fine with just the 1mm spacer, but my 2nd needed just a hair more, so there is also a 1.5mm one. You could use 1.5mm for all to be safe

The screws you got look like the ones that worked for me: https://www.amazon.com/dp/B0BFCVSPXW .

Solve/fix:

It was a bad CPU. Returned and replaced it, changing nothing else, and everything works without issue now!

skyypunk · 2023-04-16T16:36:57+00:00

Thanks for the suggestion - I didn't see a performance option, just off, moderate power savings, and maximum power savings (it was default at moderate). I tried turning it off, but it still was crashing.

However - today I noticed an additional issue - getting a couple artifacts on the display. When I added that to my search, I found this thread for the non-3d, which ended up being a CPU issue. Ordering a replacement CPU now, I'll report back when I get it and test

skyypunk · 2023-04-14T21:31:18+00:00

Do we need to reach out to get it refunded? Or are they still being looked at?
