Had you checked if the data from mobile is enabled in the settings?

 

Unfortunately so, I wish it were such an easy fix but SIM data is turned on.

 

After many months more of frustration and glitches, the dealer replaced the TCAM this and told me the car was tested and good to go yesterday. I hadn't even left the lot when it lost LTE signal again. They got in and fiddled with it and said, "oops, forgot to turn the modem back on after rebooting it," which I knew was a lie because when I initially got in, it had connectivity. Anyway, left the lot, drove 2 blocks and it dropped LTE again. My car displays "LTE" engaged less than 5% of the time, if that. Now they're ordering a replacement Infotainment Head Unit which feels like just another thing to check off the list of items which won't result in a repair. The loaner XC40 I had for 2 days displayed "LTE" consistently in the upper left corner of the screen - how about all of yours? Mine displays it so rarely that I forget it's supposed to, the first time I called support and they tell me to hold the defrost button* until LTE starts flashing, I was so confused given it doesn't even display. *the defrost button resets nothing in my vehicle, hold the button down for 30 seconds and release as instructed and all that happens is that the defrost comes on full blast

My car has also taken to often displaying that I can't switch music stations for my safety while driving.

 

They are throwing parts at the problem hoping for a fix. What update is the vehicle on?

 

In the meantime, if the defrost reset is unresponsive try doing a 12V and TCAM BUB disconnect/reconnect. This worked for me. Something to consider if you are stuck and can’t wait for another dealer visit. Good luck.

 

That sounds like what the dealer may have done at my last visit (sounded like they essentially unplugged the battery and plugged it back in, this was after the car completely failed to even start, unlock, no SOS even available, etc, other than getting it to run crippled by placing my key on the sensor inside the center console). I'll do some googling to figure out how to go about doing what you've suggested as an alternative. Volvo should really be ashamed.

Thank you!

 

We have a new XC40 Recharge. Haven’t even driven it 200 miles yet and the thing is falling apart. No GPS, no LTE, no Wifi. And now weird things in the charging screen (it’s stuck on 6 amp and the buttons are grayed out for changing it). We’ve tried the defroster button technique to reset the modem, but it doesn’t seem to do anything (maybe because we’re on too recent a software version?). We can reset the center screen with the home button but that doesn’t fix anything. We’ve let it sit overnight. We’ve tried locking it and walking away with all the keys. We’ve tried coaxing and imploring it. What else can we do, except wait 2 weeks for the first service appointment at the local dealer? Is there a physical box someplace I can unplug and plug back in? thank you!

I know you wrote this long ago but we are having the exact same issues in our 2022 C40, no LTE, no Wi-Fi, no GPS, amp limit stuck at 6 - can do the home reset but that fixes nothing - defrost reset doesn’t work. Tried resetting to factory settings at Volvo’s suggestion but of course, I can’t due to telematics connectivity error. I hope you finally got a fix but furious Volvo is selling vehicles with known tech issues that severely cripple usage. BUT if yours is fixed, can you share what worked? I’ve taken my car in several times and am getting very tired of their temporary fixes.

 

After a year of fits and false starts with software updates and every other thing, they finally replaced our TCAM. I think that’s the only thing that fixed it for us. It was aggravating as heck but the good news is that since then the car has essentially behaved itself.

I had same issues. The dealer had to disconnect the battery cable from the 12v battery. He called this a hard reboot. But today problem is back

 

 

It took the dealer 2 "Battery Resets", a call to Volvo and a reinstall of v1.8 but I now have connectivity again!

 

Having the same issues everyone else described. GPS and Data stopped working last week on my P8. No amount of center console reboots or leaving locked and unplugged can help. V1.8

 

Maybe double-check that your Volvo account is still listed under your driver profile? It seems to go missing occasionally, and re-adding it to "Accounts" seems to fix the VC app problems in some cases.

 

Now car location would be very very nice.

Isn’t there meant to be some trick with google maps that can give you that now?

 

Though the over night nap works a lot of the time it is far far from an ideal solution. I wish there was a way to induce that state more rapidly … 10 minutes would bearable. But having something broken until the next day …

Of course not breaking would be even better

Thinking about it. The over night nap fix makes things even worse for service centers as often the car is fine by the time it gets to them. Making diagnosis a nightmare I would imagine.

 

When this problem came up, I had both keys each with separate profiles and Google accounts. However, I did a factory reset to try and fix the problem, which removed all of the links. Then the problem resolved the next morning. I will have to link the keys again.

 

My car lost GPS, lte, wifi, and had the charge indicater max out at 6 amps 2 days ago. I did a factory reset yesterday and tried multiple console resets. None of it worked. Then miraculously as another person said, this morning everything started working again. So agreed that there must be some overnight reset that happens but it may not be every night.

 

See my posts about my advice. I suggest capturing video of failures and if possible bring the car in. At some point some people may feel the pleasure of the car is out weighed by the annoyances and wish to pull the lemon law card out.

 

Yeah my LTE reliability has been a mess.

 

Good luck

My voc has not been working for 2.5 days oh well. It will work again some day nothing had changed no idea why but also not that worried. As long as it’s only voc failing life (car wise) is good

 

My VOC has been working perfectly for the past month and then basically quit about 3-4 days ago and will not show SOC, so after rebooting IHU and trying everything else I knew about I rebooted my iphone 12 which got updated last week and now everything works again.

 

I do not want to jinx anything, but I may be on to something based on some events yesterday and today. I want to factory reset the car as I think there is a software/profile issue. My new phone come next weekend and if I have time I will factory reset the car and see what happens.

 

A swap might be a good idea. Be intriguing to see if your new car ends up being problem free

One can but hope

 

I have reached out to dealer to understand how a swap would work. There is a car at the port I am going to lock in with a deposit to see where this goes.

 

Or could by separate lte issues

 

I am still trying to figure if my LTE issues are 1.7 or just my IHU is acting up. My LTE was dead for 15 hours until I rebooted and still dead, tried LTE reboot never seemed to work then a little after that LTE came back.

 

Alright it is exactly the same. First lte issues, then gps and now the charge current is grayed out and stuck at 6A. No troubleshooting step helps and the dealerships don’t have open slots. Fun on a bun.

 

I got mine in July, but it just happened today. Harumph.

 

And then today, it's magically working again. I guess there's some self-repair process. Pro: saved a trip to the dealer. Con: loss of some functionality until it decides to work again, and loss of confidence in the HW/SW stability.

 

I just purchased mine two weeks ago and have the same problem now.

 

Sounds like a dying IHU. I think they do all the free software stuff first then hardware

Are they open to printouts or threads from here and how folks go theirs fixed? Perhaps people could supply contact info for their service departments (that succeeded with the problem).

The biggest issue I perceive here is that each department is solving the P8 individually. There is a seeming lack of dissemination of information. Perhaps we can help with this.

Before folks say it’s not our job … do you remember when computer games had manuals and official guides … now they are written by game players which copes with the changing nature of a game (keeping a manual up to date is a pita) and saves the publishers money. Not that I want cars to go that way yet this board is a start in that direction …

No, they were not. After they said they'd never heard of such issues before, I mentioned that in reading online it seemed that it certainly wasn't unique. The manager waved that off and said that they don't go down the "rabbit hole" of forum postings.

 

They need to replace your IHU not sure why they are waiting and trying other things.

 

Agree. I'm not sure why Volvo Customer Care has on record that it was already done. I wonder if they accidentally said the quiet part out loud.

It makes me wonder who opted to go the quick and easy route — the dealership, or the Volvo people on the "hotline" that they consulted with?

 

Since picking up our car last Wednesday, we have had to do a system reboot with the center screen button just about daily. Fortunately, we are not in the position where the car refuses to respond to the rebooting like we were the first time.

In follow-up email with Volvo Customer Care, I relayed that the car is continuing to give us trouble after the repair. The repair, based on what I was told by the Service Manager, involved a "deep reset" (that he said we wouldn't be able to do ourselves) but no change in hardware.

Which is interesting, because what Volvo Customer Care wrote was the following:

[Dealership name] found one of the control modules in sleep mode, which was causing issues. With the help of our technical staff, they replaced the module (emphasis mine), reset the battery, and all appeared to be operating properly.

I also don't see anything on the service sheet that indicates any kind of hardware replacement.

So it seems to me that there was some indication that a module needed replacement, but that instead we just got the soft "reset." This is me speculating, but I am guessing they tried to easy fix first to see if it would stick.

I'm pretty ticked off about this. Bad news for them is that I've got the next week off and will spend as much time as I need to getting to the bottom of this and who was supposed to do what.
