Happy times:
Have been loving the new car until this weekend. Went out to dinner for the first time in a long time on Friday, returned home and topped off the car overnight. Not positive, but I think this is the first time I've actually charged the car fully to 90% and left it connected for a long time afterward. Wonder if that's where things went bad ...
Sad times:
I remember car showed it was due to reach 90% at 6AM. Looked at my phone when I woke up around 7:30 and noticed the app was reporting 79%. Immediately knew something was wrong. Went out later that morning and charging cable wouldn't disconnect and car wouldn't unlock. (There goes the weekend!) Used key blade to unlock car, setting off alarm (wow, it's really loud!). After reading various posts, I assumed 12V battery was dead. Have been wanting to get a 12V charger anyway, so went and picked one up, removed the paneling (good gosh, could they make it harder to get to the 12V battery?) and connected the charger. Battery wasn't dead after all, as the charger reported 100% within a few minutes. Crap.

After more reading, decided to disconnect 12v battery to see if I could get car to reset. This entailed hearing the alarm go off, a lot. Invest in ear plugs if you have a similar situation. You will be glad. This reset the car enough that I was able to unlock the doors and also release the charging cable, which allowed me to drive it. Celebration, but not for long - car was far from back to normal. While it had actually reached a full 90% charge, it was still reporting SoS and "e service required". Also, the On Call button, SoS, key remote functionality and internet connectivity still were not working. The windscreen defrost button reset trick did seem to reset the connectivity momentarily, but shortly went back to disconnected state. Toggling the SIM data setting had no effect. Read about the TCAM issue, found the TCAM BuB and unplugged/replugged it, but this didn't fix the problem. My mistake here may have been that I didn't do it while the 12v battery was disconnected. Duh.
Note
Be careful if you go hunting for the TCAM BuB. The bracket the BuB is connected to is attached to the car by sliding onto threaded screw posts and it seems it's really designed to attach one time and not be removed. It's hard to get at and I broke one side of the bracket trying to remove it
, assuming it would just unsnap. The correct way to solve this is to depress a lever on one end of the battery, which will release the battery from the bracket. The plug on the battery is also fiddly and you need to press a tiny plastic lever to get the plug to disengage.
At this point, I was annoyed, tired and decided to admit defeat. Clearly a software issue I wasn't going to solve by simple resets and even if I could, I'd have zero confidence in taking the car any further than our immediate town and surrounds without getting some diagnostics run on it.
Current Status:
I called the Seattle dealer and they were familiar with the problem and prioritized getting me in today. The service manager told me it's a known issue 🤬 and there's a software fix for it! He couldn't explain why this fix isn't getting applied during manufacturing or at port/delivery, as they've already seen 3 cars with this exact behavior and issue. He was equally dismayed at this. Maybe it's still early. He did say they would open a case with Volvo since the car is only a few weeks post-delivery. I'm hopeful this helps them push along this fix/patch they've come up with to get rolled out to all new cars.
I'm thankful here for two things. 1) I wasn't at a public charging station somewhere when this happened. Trying to imagine all of this troubleshooting at an Electrify America stall in the parking lot of a Walmart with my family in tow. 2) This website - I was at least able to get the car into a drivable state thanks to helpful info from previous posts in this forum.
Will post again once I pick up the car and share the details of what I learn from the dealer. Really hope most of you never have this problem. What a crappy way to start ownership with our first Volvo.
