I had my coolant reservoir topped off last month. I'm continuing to monitor it for change. Dealer did suggest the next step would be a pressure test.

Looks like I’m in the same boat. I took a look this afternoon when doing the frunk beep removal and saw similar low coolant level. Sounds like consensus is just buy from Ford and grab a funnel and level it up a bit?

Yeah that's what I did. When I took delivery in October it was right around the 'MIN' mark. Over the course of several weeks I noticed it dropping. I filled it up to about halfway between the two marks and it hasn't moved since.

Happened to me after my battery module got replaced. Had to top it off after each trip a handful of times before it stabilized. I assumed there was air in the system after the module replacement.
Has yours remained stabilized or have you had future issues? I just had a module replaced, lost cabin heat, noticed empty reservoir, filled it, drove for an hour, empty again.

It stabilized and hasn't needed any more top offs

Man I love this forum. I was getting some stuff out of my trunk tonight and noticed my reservoir is empty. I did have a battery module replaced a few months ago so I'm chalking it up to that. I'll be running to the dealership to get a gallon just to have.

I’d tell them that they owe you a gallon for not filling it properly when they serviced it.

Yea, I'm sure they would top it off for me with no argument. My service manager is great. However, the dealer is 30 minutes away (1+ hour round-trip depending on traffic). It's worth it to me to order a gallon for $25 on Amazon.

If you have anything else you need, rockauto was like 11.76 for a gallon, just had to use my 2011 as the vehicle for the the vc13 type to show up.
I’m guessing with shipping it’s still less than 25 even add in 5% code from rock auto.
