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

Sorry you are having such bad luck.

I do not have the new software but I thought they removed the defrost reboot and just merged it with the home button reboot.

Another option is a factory reset.

Other than that it sounds like you have done the normal tricks including the all important let it have a nap. These are a) often needed when you first get the car and b) things normally settle down after.

It is possible your car has some corrupt files. I have heard of people who somehow managed to get corrupt data files into the car. How this happens in the modern era I do not know. Been a long time since I saw a corrupt file without the underlying media going toes up but …

Hopefully taking it in will allow them to do a clean re install. The car might still be twitchy until it has had its first nap but then should work.

Have you tried calling around see if anyone else can get you in sooner? Or try being pushy. 2 weeks is a bit of a crappy wait

Good luck. Let us know what happens.
 
Not the car it’s the software layer on top. The car is awesome and for most the software is good as well. Seems like you either got an unlucky corrupted file or a bad bit of hardware. Covid made many manufacturers go to alternate chips which leads to a vastly more complex number of permutations :(

Hang in there. The really bad thing is the 2 weeks :(. Still at least the car drives fine minus the gps. Have you tried charging at a commercial charger? Might reset the charge screen. Also is it charging fine? And it’s just the screen that is wrong or is it also not charging?
 
I am wondering about words.

When we say dealers do we mean
A. Sales team until we get the car
B. Sales team after we get the car while they forget to order free stuff over and over and the important part
C. Service when the car has an actual problem
Or
D. Sales when the car has a problem

As far as I understand our contract is with Volvo service(s) which are the service departments of all Volvo dealerships. None should shun service all should treat us as a Volvo owner. And in my experience have always looked after me.

Sales departments (some/mine) barely gave a crap before I got the car and I certainly would not go to them for problems I have with it. They cannot give you a new car but they can champion your cause with sales.

So when I said go to another dealership I meant the service department of another but due to the inaccuracy of language I was probably not clear.

The number of P8s with bad cosmetic problems is low but it is not zero. So far all of the problems have been fixable with a competent service team working with Volvo. Not always very speedy but that should increase as they learn symptoms and link with cures better.

Good luck getting your car working.

Ps I call gps cosmetic but ac is not cosmetic esp in the heat of summer or cold of winter.
 
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 punching above its weight class in both engineering and in its management of its dealer networks and service departments.
Anyone know a Volvo email address for this chap to elevate his problems on? Service should not be treating people like that.

I did not realize your car is not able to communicate with their diagnostic equipment. It honestly sounds like your car is not viable. As someone else said. Drop it back to your original dealer. Demand (I hate demanding, I hate it so much that I get my wife to do it. I like asking nicely which works in most situations but not around some car dealerships) that they either replace your car or give you a loaner whilst they fix it. A nice loaner.

Sorry you are having to deal with such crap :(

What leads you believe “The number of P8s with bad cosmetic problems is low”? Do you have data from Volvo?
This is based on surveys I and others have run here and the fact that if the number was really high the number of people complaining vs not would be higher. Is it 100% accurate no but it is the best info we have.

I do wish Volvo would share the data.
 
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.
<makes frustrated sounds at the rabbit hole comment> Probably made sense in the past but this is not the past …
 
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 :)
 
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.
 
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?
 
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
See the thread on tcam water leaks and book an appointment to see service.

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!
Honestly most modern electronic systems are the same. My nvidia shield needs to be power cycled somewhere between every week and 8 months.

My computer monitor is the same. Works flawlessly for a good 10 months then forgets how to handle an input. (It’s a 1200 dollar monitor).

The problem seems to be
A) volvo did not build an easy way to power Cycle the car and all its components.
B) A is probably secondary to volvo believing the engineering / design or marketing team promising stuff would work without power cycling.

If they would just add a couple of power cycle options most of the problems would be very minor.
 
Volvo needs to find a solution to a problem they created or they need to recall the vehicles to make it right. I'm not taking a screwdriver to disassemble parts of my vehicle to access a battery to reboot it. That's an unacceptable/intolerable solution, not to mention, I can easily see them saying you'd void your warranty for messing with it that way. Let's set aside just not being able to use music apps, etc, for a second - these 24-48 hour glitches are not safe either - what would happen if I'd have been on a road trip and no longer able to charge at greater than 6 amps, nor plan my trip around charging, etc, because GPS is down?

BTW, my car spontaneously started working again yesterday before I was able to get it in to the dealer. This wasn't after it's overnight "nap" but later in the day while out. Coincidentally it was parked across from a Volvo dealership when it magically started working again. Volvo customer service claimed the amperage glitch (stuck at 6) was unrelated to connectivity issues but surprise, surprise, just as others have described here, everything went down together and returned to normal at the same time.
Agreed they need to recall and install a reboot switch. Preferably in all cars but at least in those struggling.

A volvo approved boot switch option that the dealership could install would be a step forward!

I also fear that installing such a switch without it being approved or doing the reboot via a screw driver feels like something they could say is a warrantee breaking issue.

All in all getting a solid full system reboot option for clients would make their life a lot easier.

Caveats to this. Can a full power reboot leave the car in a worse state than it was initially in. This has been rare in my experience with computers but not unheard of.

My gut feeling is that it would be very rare in the cars case to go from unstable / twitchy to bricked after a power cycle.

I actually see power cycling in the future as one of the early suggestion by volvo on call.

Yes sir. I understand the car is having problems. Have you tried power cycling the car. . .

Good luck with your problems. Wish there was somewhere official to suggest these changes :(

Cheers
