Our 2 month old XC60 with the mild hybrid would not start after being parked for about 30 minutes.
Volvo's roadside service could not jump start it with either a fully charged portable jump start kit or from his running truck.
He also could not tow the vehicle because it would not come out of Park and he had a flatbed tow truck.
A few days later after it was towed to the dealer and analyzed, here is some of the feedback from the Volvo service advisor:
1. A problem with a small battery in the shark fin antenna was causing the main battery to drain.
2. It would have taken at least 30 minutes of charging from the tow truck to be able to start the vehicle.
3. It is recommended to never try to jump start a Volvo mild hypbrid vehicle due to the complexity of the battries and how they are interconnected.
4. It took 14 hours of charging at the dealer to restore the battery.
5. There was never any indication of a battery discharge issue prior to the vehicle becoming inoperable (no warning light, no message, not hard to start).
6. The dealer said another vehicle with the very same issue came in right after mine.

Anyone else experience this?
I am not very comfortable with a vehicle that dies unexpectantly, can't be jump started and can't be towed by a truck that requires the vehicle be put into Neutral.

 

Possibly related to this "Service Campaign?"

 

Possibly. The dealership did the action "TCAM backup battery remove/install/replace", but did not mention that service campaign or seeing a gap between the antenna cover and body.

 

I've seen that recall before, don't think my VIN is included. I'm also very curious re: what you were told about a small battery in the antenna fin causing a drain. I've never heard of a battery there and can't fathom what it could be powering. Being from the 'Show Me' state of Mo., I'm thinking you may have been blowing you off.

Does anyone else know of a battery in the fin and what it could be fore???

 

There’s a battery in the Shark antenna? Huh.

Maybe it’s for the connected systems in order for owners to send remote commands or the system to receive updates?

 

I understand from the dealer that the TCAM backup battery is at the base of the unit and is the size of about 2 AA batteries.
This vehicle sure has a lot of batteries.

 

Being as the antenna is/appears to be glued down probably w/adhesive tape, I would be supprised if there is a replaceable battery there. Could your dealer have just given you a line of b****???

 

The point of service campaign A10140 is that in some cases the antenna cover adhesive does not bind to the body and allows a leak. The associated corrective parts bulletin is in fact tape. I do not think the battery is expected to be replaced, unfortunately in my case the flaw led to also discharging the starter battery leasving the whole vehicle inoperable,

Similar issue. I have a 2010 XC60 3.2. I hit a really bad pothole, and ended up having to be towed to the tire shop, for a new back tire, the other was fixed. A few days later, I hopped in and...nothing. No dash lights, dinging, just completely dead. I tried putting my fob into the slot, and it kept popping back out.
I jumped it, and there was still nothing, even for about 20 minutes. Checked the both battery fuses, and they were fine. I was going to take the battery to the shop to have it checked, but can't get it out, because someone didn't put my tools back, and I can't find my 8" 1/4" drive extension.
So, I decided to hook it up to my charger, and the bad battery light did NOT come on, so I left it on the charger. It's been charging for about 10 hours, and still nothing...
Anyone have this experience or any ideas on what to do?

 

I have a 2022 XC60 recharge. I drove it last weekend. It has been in my garage charging since then. Tried driving this evening...totally dead. No sign of life and it has been charging since the weekend.
Can not get the charging cable out
Not sure how this happened? You can not lock the car with the car running, but wonder if you can once the charging cable inserted? The car was locked etc when I tried to open the doors tonight. Took the KeyFob apart to get into the car. Dear as a doornail....

 

When Volvo introduced the 2022 model, they went to Google for most of the radio and navigation components but I think the basic engine and charging sequences for the T8 (recharge model) remained largely the same. The one thing I know is same between your car and my 2021 model is similar amongst all the manufacturers electric models. Once you insert the charging cable and the charge has started, you have to 'unlock' the car to physically remove the cable. In other words, it locks itself to the car. Even if your cars doors are unlocked, the cable is still locked to the car. You can use your key or your hand in the door handle to run the 'unlock' sequence. That sequence protects all of the various charging circuits by properly shutting down the charging system in the car. If you listen when you plug the cable into the car, there are a lot of clicking noises with various relay's opening and closing. Some of that noise is the cable locking into place. My 2018 Honda Clarity PHEV did the exact same thing, it's normal for the electric models.

In answer to your other question, yes. You can lock the car when it's charging. Often when I go to Whole Foods, I plug into the courtesy charging cable and lock the car when I leave it. And 'NO', you cannot leave the car running, lock it and walk away. Why would you?

If this is your 1st electrified car, there is quite a bit to learn. The manual can be downloaded to your PC, tablet, and/or phone. It's good to read up on all the systems. I love my T8, hope this helps you.

 

Thanx for the reply.
My question is: could I have plugged in the charging cable with the car still running accidentally. Then used the key fob to lock the doors so it would charge? I wouldn't want to do that - but could I have done so?
I know when I first got the car I parked the car and thought it was off, but it was still running. I discovered this when the car would not lock. So can not accidentally lock the car with it running (this is good). But, if I plug the car in could I have locked it with the car running? (wonder if I killed the car's battery somehow ?

 

Look up Technical Service Bulletins on the year, make, and model of your car. I had 29 and 3 seat belt recalls.

 

Also feeling very uneasy.
2 month old B5 mild hybrid- sudden red message “ critical 12V battery failure; stop vehicle immediately “. Complete loss of power.
At the dealer today ( they’re waiting for feedback from Volvo Sweden). Will update tomorrow

 

Same thing happened to us last week - we have a 2022 XC60 B 5 inscription AWD - we've had it for six months, it has 7,000 miles on it... other than the crappy google entertainment system, we have had no issues to date. Last week, we came out to drive it and it was 100% dead. Neither remote key would work, no lights, no alarm nothing. We used the manual key to get in - popped the trunk and tried to jump the car using a portable jumper we have. No warning at all. No luck whatsoever getting it to do anything.

We had to call Volvo roadside assistance to have it towed to a local dealer in Nashville. No word on the problem on Friday, and they were closed all weekend. On Monday, I got a call from the dealer that it was a battery drain issue with the Tcam module and battery drain. They said Volvo NA engineers got remote access and did a software patch. The dealership then charged all batteries including the one in the TCAM and now everything seems to be working. I'm picking the car up later today so I will have the report of exactly what they did.

I blasted Volvo NA on Saturday because this is a known issue and is a serious safety problem. I brought the car down to my son in Nashville for him to pack it up from school and drive it back home. He's been waiting for 4 days to get it back.

While the Volvo dealership in Nashville was great, Volvo NA did not offer to get us a loaner or a rental - zero communication. For a $55,000 luxury car, I'm still in shock.

 

Just had the same issue with my brand new XC60 after only 2 weeks driving it.
Sending the car to the dealership tomorrow. They should fix all known problems before delivering a new car. Very disappointed.

 

I purchased my brand new XC60 B6 in December. The endless software update problems, the remote start app working 10% of the time, and now this: like other posters I went out to my car one afternoon and it was dead as a doornail. I had to use the mechanical key to unlock it and get in. Called Volvo Roadside Assistance, which took THREE HOURS to come. Boosted battery then got "STOP SAFELY, 12V battery critical charging fault" and the red SOS indicator light and exclamation in triangle red warning lights. White knuckled the car down to the Volvo dealership. It's been there THREE DAYS now and none of the people in the service department can figure out what the issue is and no idea when I will get the car back. It seems they have had to consult Volvo HQ about this as they do not possess the troubleshooting gear/skills to figure it out. Last time I spoke with the service advisor he told me that I may not get the car back in a LOOOONG time. Car is six months old. No idea what the problem is. No idea when I will get the car back. Not even sure they will fix the endless software update issues or get the remote starting working again.

 

Absolutely NOT the same problem. I had that fixed back in February and still got the 12V critical charging failure. See my post further down.

 

Nope... for model year 2022, there's no longer a manual that you can download... Brain fart by Volvo/Sweden and Volvo/USA.... All that's available are much-abbreviated manuals in the car infotainment screen and online at the Volvo website...

 

Good to come to this forum seeing the same problem is happening and not only to my Volvo XC60 B5.
Day 1 - I drove 200miles away from home for a vacation
Day 2 - Drove around 30miles within that town, parked the car at around 9pm
Day 3 - 8am, wanted to load my luggage, surprise that i couldn't unlock my car, called their Support Line and they sent a tow truck to bring it to the nearest service center
Day 4 - got the car back, was told "no problem with the car"
unpleasant experience stranded 200miles away from home.
when confronted with Volvo on the matter, their response was,
"your car is having a low mileage, the battery state of charge is low"
they claim if i don't tend to drive 12,500miles a year, i'm not a worthy Volvo owner.

(NOTE : in earlier message, low mileage = less than 12,500 miles a year)
