Sound of running water

Good morning everyone,

I just got my 4xe back from the shop after a PIM replacement. All seems to be running well except a sound of running water coming from the battery area. I’ve never heard anything like this before so curious if anyone knows what this could be?

Thanks for the info! Extremely helpful.

Took it in before I saw this post and they said there was air in the coolant system which may have worked its way out since the sound was gone. So they topped off the coolant and sent me on my way. However, the sound came back after battery temp increased. Called the dealership immediately, and they want me to bring it in Monday. Unfortunately, this leaves me without a vehicle over the weekend since I don't think its safe to drive until the coolant system is bled correctly as it can cause the battery to overheat. Am I correct in that thinking?

Update. Dropped my 4xe off a day after I posted this and it is still at the dealer. The dealership would not perform any work on the battery area until the recall for the connection seals was done to prevent any injury to their tech since their was a running liquid noise. Took a couple weeks to get the seals shipped in. Once the seals were replaced they opened the battery shell and found that there was a leak in the battery coolant hose. Thus another part they need to replace and is on back order. As of today my 4xe has been at the shop for 58 days.
