So what’s the new way to reset the modem?

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!

Yeah we’ve tried all the button press combos, reset to factory, done the magical dances and incantations.

This is like a radio shack hobbyist kit. Volvo should be ashamed to have this out in the wild.

@SeattleCat I appreciate the cheerful disposition. I called around and have another dealer able to squeeze me in on Thursday. They said one of their vehicles exhibited the same issue while it was still on the lot.

I hope that Volvo can get a handle of this problem quick and that it doesn't recur for us. I'm sure we'll grow to love the car quickly once we feel like we can trust it.
 
the car is not falling apart, it's just the networking having issues, you can still drive it just fine without LTE or Wifi. It happened to me one night (LTE modem went offline) and it was back by next morning. Remember that LTE is the cellular network, so in some cases it could just be the cellular network being down, though in your case it definitely seems to be a software issue given that GPS and Wifi also don't work. Probably a faulty antena module, let us know what the find, please.
Um nope. it’s busted
Oh my way to dealership 2 of the day (back to the place it was purchased, a few hours from our home).

Not only is all the connectivity stuff broken, but the car is stuck in hobbled charging mode and apparently will not connect to VIDA. The first dealership I went to wanted nothing to do with it, and basically just shrugged their shoulders and said take it back to place of purchase, make it their problem and not ours.

all well and good, But no customer should ever be on the receiving end of this kind of BS. I’ve been in the car for almost 6 hours today, and the vast majority of the miles on that vehicle are the miles driven around this **** state trying to get a resolution.

I have bought six cars in my lifetime. Six out of six have been Volvos. That one we bought on Saturday is the very last one.
 
Nothing about this is “cosmetic.” Functionality of the vehicle is greatly impacted by having not just gps, LTE, and wifi not functional. This is one of the reasons we traded in an older V60, and we paid for every bit of it.

The car is not charging correctly. It charged like it’s plugged into a 110V household socket, even on the dealer’s own charger equipment

The car cannot communicate with Volvo’s own VIDA diagnostic system.

A dealer decided that it was too much of a problem for them to handle because I didn’t buy the car there (because they didn’t have the car we wanted in their inventory). Okay. Not sure that’s how a service network is meant to work. I was a model customer — had all my issues written down concisely and even stopped by to pick up some snacks for the service dept. lounge to just say thanks for getting me on the appointment calendar this week. They treated me like crap, and even (wrongly) told me that the orange key I brought to have reset to a full-functional key couldn’t be changed (they didn’t know their own TJs).

I wrecked the rest of my day to drive halfway across the state to drop the car at the dealer who sold it to me. So they win, and I’m greatly inconvenienced. Fine.

They’ve lost Volvo two customers in our household who’ve never bought anything but this company’s product. They’ve convinced us that Volvo is trying to punch above its weight class in both engineering and in its management of its dealer networks and service departments.

If y ou really want to contact Volvo, its only a matter of doing some GOOGLE searches and you will find what you need. I did! Complained enough and I was financially compensated for the problems we experienced. BUT I was polite and not demanding. Remember you get more honey.....
So are you saying you googled and found more than just the defroster button, the home button, and maybe unplugging a couple of things under the cargo area? Because that was all part of our attempt.
If so, I'd love to hear more.

When you let it sit overnight, did you Power Off, and not have charger connected? My P* had a similar problem and it recovered after powering off and letting it sit idle while I was out for the weekend.
I think we probably did have it plugged in. If it happens again (oh god) we’ll try this.

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.
1206



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.

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?

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.
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.

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.
