How many people are having connectivity issues?

[Dangerous Fish]

I believe it's not just MCU1 cars affected. Model 3 and Y are too. In any case, I'd probably just buy a cheap mobile hotspot and put a Lebara SIM in it before I'd consider spending £1400 on the MCU2 upgrade. At the moment I just always put my mobile in hotspot mode when I get in the car. I never get through all 15GB of data on my contract anyway.

I'm chasing a problem we have with Track Mode in the Model 3 but it only affects Intel Atom-based models. Ryzen works OK.
When I spoke to them about they suggested there may be a link between that and the connectivity issue. I'm not convinced of that myself, but there's a possibility.
So just because it's a M3/MY doesn't mean it's not related to the MCU/GPU.
Has anyone compiled a list of affected owners with details of the model of car & GPU affected and locations/timestamps where it happened?

Sometimes you just have to do some of the work for them if you want something fixed...

My previous support request has been closed. I'll raise a third one with some more time stamps.

Mine is on and off at present. A week can go by and be fine, but then another week I have to reset multiple times. I haven’t heard anything since my last call with a "manager" from Tesla. I currently have an open service request for a few other things, but i will also ask again and push for a better response. I was thinking of obtaining a separate sim card and phone to keep in the car and hotspot from and run a bill from that and sent to Tesla.


A few times recently it has been a right pain not having connectivity, especially with this hot weather and not being able to pre-condition. Arrived at a destination where we were having lunch, and the connectivity seemed fine when we go there. I plugged in at a public charge point, set it up and was charging and left for about an hour while we ate. Checked the charge while we were eating and alas no connectivity! Got back to the car hoping to have about an extra 40-50 miles….nope. Only 2 miles had been added and for some reason the charging stopped. Luckily it wasn’t imperative we had that charge, it was just a nice to have rather than paying for parking. But still very annoying.


This lack of connectivity is not making the owning experience of the car very pleasant as many of the functions to use are redundant when you don’t have connectivity.

I used to use YouTube Music on Android Auto via my Phone's connection, it allowed you to have offline playlists for times when you lost connectivity.

Would be good if Spotify could do the same with the USB drive.

mine is Ryzen.

But issue I think is with esim and way it jumps between the towers. remember - operator is dutch and all cars in uk essentially operate on roaming..

Looking back at some of the posts it doesn't seem clear cut between Atom and Ryzen, for sure, but having as much information as possible can't hurt. Ultimately, Tesla have the most data and if they haven't been able to see a pattern, I can't see how they're going to fix it, especially if it's a problem with the operator.

change esim operator... :/

Mine's an Intel Atom car, I thought it had been narrowed down to the way the eSIM hope between masts, on the specific frequency it uses.

I didn't know that. Where is that information?

 

[willdashwood]

I don't think chipset has much to do with it given I'm on MCU1 (Tegra) with a physical SIM (not eSIM) and 4G LTE modem. I suppose it might be interesting to see if there are any Tesla's that are not affected by this issue. But you'd hope Tesla have collated that information by now.

I think we've just got to keep pestering Tesla and update/raise support requests with all the data.

 

[The_Kilt]

Is anyone experiencing similar issues with any other device or car? I have mentioned it previously but my iphone (With Sky Mobile) has issues in certain locations. Annoying in my local town I have full 4G signal but nothing loads, a very similar issue with the Tesla.

I don’t have any experience with other electric cars, or other “connected” cars which utilise the 4G networks so it would be interesting to see if this is just a Tesla issue, or is it more widespread.

exactly

in few early pages, that's for sure

Yep, as @yessuz says in this thread, presumably someone who may work in the mobile industry.

I just put in a service request and was surprised that there was an unable to DC fast charge take to service centre warning, don't remember seeing anything pop up for that, it's dated 14th May which is when I did the update to 2024.14.6 I think.

 

[pdk42]

Of course, the UK GSM network is generally crap. That doesn't help.

 

[Roy Batty]

Well the remote diagnostics have been done and the car is going in for both the DC charging problem, it's the HV sensing circuit apparently which needs changing and multiple problems have been found with the connectivity, maybe requiring an antenna but they'll diagnose further at the service centre.

Edit to add that I'm also currently getting a connection failed in the App when trying to schedule a service, odd.

This problem is with Tesla’s firmware: the SIM card firmware fails sometimes to switch back on when the connection drops. This is a problem that Tesla has been aware of for years but have failed to fix it.
There is a work-around. If you add your own sim dongle (use the spare usb socket) and connect it as if it’s a WiFi network it will use that instead of the internal sim - in a similar manner to using Personal Hotspot on your phone.
There are lots of people on here suggesting a reboot but that is not the solution with this.
Come on Tesla, nearly every customer you have with older cars has this issue - please fix it!! It’s just a little bit of code - a decent techie could write it in 20 minutes. Newer cars have a different sim architecture that doesn’t have this problem, and Tesla recommend replacing the cars processor and screen for $2000 - a bit like replacing an engine because it has a loose fan belt.
Please feel free to cut and paste this response to lots of people posting the map issue so they know the real source of the problem.

Same here. Lost all connectivity for half of my last trip. Map broken, routing with no traffic data, especially in the heavy Christmas traffic was a nightmare.
I'm wondering why I'm paying for premium connectivity. Tesla should refund us for the last two months at the very least and offer a fix ASAP__
Shame for a 'connected car' to reveal itself inusable if there is an unreliable network issue.

well that is not the solution (the dongle).
because what you could do, alternatively, have an automation that phone enables Hot Spot on the phone once it connects to car's BT. so then car sees the hotspot and connects automatically. Issue is - it has some delay - 10-20 seconds sometimes.

but in such case you would avoid additional HW connected to your USB socket

Same here, really annoying car.
