Low cooling fluid issue

[Runeglfbrg]

Question- does the system that cools and heats these motors, batteries and whatever else share common lines and coolant? In the diagrams I can find it only has one coolant reservoir. Also does it transfer or pickup its heat or cooling through the heat pump? I ask because for a week or two in Chicago it was 20 degrees or less. Which is the first cold since I took delivery in April. A bunch of issues all popped up that week. Front motor would disable, heat pump would scream like a banshee, snowflake would never leave, even when garaged in the heat, and it would stop at 72% due to cold soak. Even if I set up for precondition it wouldn’t get rid of the snowflake. I drove 50 miles and all over for two weeks and no matter how low that 8% of blu bar wouldn’t go away. Finally got it in for service last week. They had it a week and at first couldn’t find any data about the front motor being disabled for a week straight. Also took a test drive and claimed the battery issue was normal. I luckily had pics showing the codes from the disabled front motor and they decided to dig deeper. They put in the notes they found the front motor to be low on coolant so it couldn’t heat it up. They filled coolant to correct level. Well since they did that it now seems to have fixed all the issues. My battery will heat when I plug in at home. And snowflake goes away after a few miles. The heat pump is now quiet and not just at 100% all the time. So even though the service center won’t say so. I’m guessing that all systems must share coolant. Since there adding coolant fixed all my issues they claim I didn’t have. It’s been the first time the little flames show up in my app saying it’s heating the battery when plugged in. Also thought this might help someone else who might have the same issues and find there service center has no idea what to do.

Yes, one common coolant system.

Also does it transfer or pickup its heat or cooling through the heat pump?

Yes, both.

I had one issue a few weeks ago with a bunch of errors- turtle mode, unable to charge, HV Batt, etc. They went away and never came back again, but service today was able to check the logs and also found coolant to be low. That caused temperature fluctuations within the pack. They refilled and performed air purges, verifying proper temperatures within the pack.

Yes I have a feeling this will be a bigger issue they find. But until they document it the service centers just throw darts at the wall. Mine happened again today. But I noticed this morning a lot of air bubbling in liquid sounds. Like air in a hot water radiator. I get in to go get lunch and disabled front motor. 10 min down the road then the snowflake popped up. So you get many symptoms from an issue with that one system. The SC claimed it was normal to have the snowflake on all the time and never go away. But once they refilled it almost never came on. Until today’s issue again.
