No cell, wifi, hotspot or GPS

Their call back was not until Saturday while I was unavailable. I called them today and finally convinced them that service was needed. They admitted it could be TCM.

Nearest SC in Bellevue, Wa was 2 months wait but they have me in at Auburn next week.

Appointment was for tomorrow but replacement TCM has not arrived.

Final update:
Vehicle fixed.
Dropped at SC on Thursday 18 April. TCM unit was replaced. Originally told one day, but vehicle would not perform firmware updates. On Friday updates loaded. I could see status of vehicle in app by mid afternoon, but they could not finish by EOD (5pm). Vehicle finally ready on Monday.

I commend the communication from David at the Auburn SC. He comped me tire rotation for delay too. It is a shame that the software issues created a 3 day fix instead of 1.

Loan car was by Zipcar with exclusive use by Rivian SC. I used a Bolt. I liked it. Smooth, quiet and rattle free. Only issue was the driver seat that had uncomfortable lumbar support.

I live in NW Seattle. There is a very high density of R1S here. It’s time for Rivian to open a SC in the highway 99 auto corridor somewhere in N Seattle, Shoreline or Lynnwood (pretty please).

Software reset didn’t work.

Called Rivian and vehicle restart didn’t restart the vehicle. Advised to wait through sleep cycle and try again.

Anyone have similar experience?

This exact same thing just happened to me. I can't restart the vehicle and it won't connect to WIFI or the mobile network. I have an appointment with Rivian service on Wednesday.
How did yours get fixed? Did it start working on it's own or did you need to have a part replaced?

The full history is documented in multiple posts in this thread, but to summarize:

The TCM (Telecommunications Control Module?) needed replacement.

If that has not been diagnosed yet and it becomes the diagnosis then it will not be fixed during your first visit . A new unit needs to be sent from the factory. As the car is drivable you may decide to take your car home until it arrives as it may take over a week. Can roadside assistance make that determination for you so that you don’t waste a trip to SC? They did for me.

They took less than a day to switch the TCM, but firmware and software updates did not complete successfully first time and it was not ready for pick up for 2+ days.

Wow! OK. I happened to be driving near the service center anyway, so I stopped. Luckily, there was a tech available and he came out to give it a quick look. He said it was a more serious TCM problem. I didn't know what that meant, but I had them add that info to the ticket. I'm guessing that this will be multiple trips.
Did they happen to say if anything you did might have caused the failure of the TCM? I haven't done anything out of the ordinary. However last night after I had plugged the truck in, an hour or so later, I heard a quiet whirr sound coming from near the front bumper in the center. Not sure it that has anything to do with this problem though.

It was covered by warranty.

There a couple of other threads documenting this happening. It is not owner fault.

Thanks a lot. I really appreciate your help. This is really the first thing that has come up with my truck in the year that I've owned it. But it's still a bit of a bummer. Still, my buddy bought the Ford Maverick at about the same time, and he says he's lost count of the number of recalls that he's received for it.

Yup. Got mine replaced last week here at Brooklyn.

Service techs confirmed that it (TCM module going bad) happened at the same time the push was done to the vehicle for the OTA 11.02 update. Perhaps just a coincidence, but that was what was told to me.

Mine started losing cell connection shortly after software update too. At first it was intermittent and then totally dead.

I hope they have found a better supplier for this unit or fixed the quality problem.

Interesting.

Mine never got the actual update just saw "Unknown version" and lost GPS/telematics, etc.

Hopefully it was a one off...

Update: the service center disconnected the 12 volt battery and discharged the system. Then restarted and it all worked. They said that there were no messages of failure in the log. So it seems mine was just a blip of some sort.

I have seen that solution in another thread.

I suggested that to Roadside Assistance ( it can be done by mobile service) but they booked me in at SC and ordered a new TCM in advance . I hope they are not doing unnecessary and expensive work but I have a new unit now.

hey all, first post here. new 2026 rivian r1s owner. just had this issue pop up this morning. symptons were

no LTE
no wifi
bluetooth good
hotspot was on, but couldn't turn it off
GPS worked, but couldn't give range estimates

tried soft reset, no go
called service line, encouraged me to to do hard reset. everything seems to be working after that. i know some people caution against that , but he had no hesitation in suggesting it. maybe something different for the gen 2's.

we will see if it comes back. i have service scheduled for the 16th just in case.

only thing that has been different since ownership but adding the digital key. not sure if that triggered something or caused an issue. no issues at all before that.

i know some people caution against that , but he had no hesitation in suggesting it.

Hard resets are common, although some have to do it more frequently than others. I've done maybe 6-8 in my 18 months of ownership (Gen 1 R1T), usually after a new software release.

For the record, they are referred to as:

• Infotainment Reset (aka Restart the Software)
• Full Reset (aka Restart the Vehicle)

Really, the only worry about Full Reset is that some systems may take longer to fully come online (possibly up to an hour), and doing another Full Reset in that time might mess things up. Other than that...reset away...
