Just picked up my Mach-E premium extended on Wednesday. Was about to drive home yesterday and saw an alert saying the car needed service. Fordpass gave me two separate errors overnight. It was -10 degrees last night, so I’m hoping that was the reason for the error.

Cold weather shouldn’t do that. Did it go away? It would be interesting to plug in an OBDII scanner to see what codes it’s throwing.

I would definitely have the dealer try to diagnose it (fingers crossed they know how), but it may in fact be telling you that the battery performance is affected by such cold weather. Tesla (and I think chevy) just show a snowflake icon on the dash to let you know the battery is super cold, but perhaps this is a dignostic/debug the ford engineers left in the code (happens more than you'd think).

Sitting in the car now, and the error isn’t showing up on the screen anymore. It was very strange last night, the heated seats and heated steering wheel weren’t turning on. Everything seems to be working fine now though.

Maybe it was related to the cold then. But, as Tim said, that’s not the error they should be displaying for that.

FOR SURE!

It's probably a very good idea to leave your car plugged in all the time at home; as I understand it most BEVs will warm the battery a bit when plugged in even if fully charged (don't know if the MME does). The good news is that there isn't any permanent damage done to the battery in really cold weather without that warming, it just doesn't perform as well as it would if it were warmed.

It needs to go back to the dealer. If you would like. Retrieve the codes and I can look them up for you. It looks like you can retrieve codes with the bezel diagnostic routine.

Agree. My car asks to be plugged in at temps below 32 and above 97 degrees F.

shouldn't have any errors on a brand new car. Suggest taking it in even though the error went away. Although I am not to confident the service will have the training yet to really tell if something is wrong or not

Agree. Must go back to the dealer.
They are trained well enough. The service manual reads just like all other Ford vehicles so they will be able to follow the pinpoint tests and get to the issue.

That particular message is the sort of message that will set codes and freeze frame data. They will definately find some codes.

When I got that message on my car.... Ford called me at home and told me to take it in (I had already dropped it off at the dealership earlier that Sunday morning....). They stayed in touch with me throughout the diagnostic and repair process. It took just over a week to make the repairs because a part had to be sent via air freight. Has been perfect since.

Pulled up the diagnostics and couldn’t find any error codes.

Can the MME display the battery temperature? I can use third party hardware to read the CMax Energi battery temperature in real time.
-10F in Minnesota is not too uncommon. I have seen as low as -29F in Northern Wisconsin (Jan 2019) and multiple -0F over the years.
