Last Winter, our 2019 had issues with charging as my wife was returning from a 300km winter road trip at below -20 C temperatures. It was not charging well and she was getting significantly less than optimal range. It culminated in a Tration Battery Fault message and limp home mode..She pulled to the side of the highway at night and waited for a to the dealer. It turned out is a failed 12V battery.

Since then we haven't had any problems until last night. -18C (not very cold) parked outside as she was working night shift. She turned on Vehicle preconditioning before going out to the car for 10 minutes (Car was at 70% charge). She went out and it Wouldn't start - Traction battery fault message. She returned this afternoon as the temperature warmed to -5C and it started without issue and without the Traction Battery fault message. . took it to the dealer and awaiting word from the dealer on the state of the Traction batteries or the 12V cells.

Does anyone know if the Vehicle preconditioning runs off of either of the 12V cells or off the main battery? Wondering if this is might be a cause of the sensitivity to extremely cold weather.

Thoughts? Any similar experiences?

Wow, you and your wife are EV frontier pioneers. "-18C, not very cold". Danm, that's a bold statement. Kudos to you for having an EV in that climate. You know already that you have to be ready for unexpected issues, which you clearly are. My simplistic take on the issue is that you need to precondition for longer. The battery has a huge mass, and getting it into a good temperature range for activity (charging or driving) takes a while. See if that makes a difference.

P.s.: Are you in the Yukon or northern BC? You're posting at a reasonable hour for the West, though perhaps you're a late bird in the east :)

Northern Alberta. Would like to hear how the Ipace is fairing in Norway.

-18 is cold but not crazy cold. Last year we had a long spell of -25C. and a few -40 nights. Our garage isn't heated but it is protected. The coldest the garage gets is about -10. T shirt weather.

I had that issue pop up but it went away. I am in Toronto. I would not buy an electric car if I lived in Northern Alberta. The winters are too cold.

Hi,

I went through the winter here in Montreal without issue. I do park in a garage all winter but it has spent many days/nights parked at the outdoor airport lot (I flew 2-4 times a month pre-COVID) and never had an issue even during cold spells with no pre-conditioning (forgot to program a wake time). While the range goes down, it is not important if you plug at home and mostly do communing and the instant heat is nice.

FOLLOWUP: left it with JLR Edmonton for a week. Got an F pace as a loaner nice car. More responsive Infotainment. But sounded like a diesel every time the stop/start fired up at a stoplight. Drove like a truck.
The HV specialist ran diagnostics. Turned out it there was a “Slow relay” codeP304F-72. The relay was stuck in the open position. They updated the BECM ecu software. Cleared codes and ran fine. Diagnostics check out. Got it back. Happy to be home.
