02/03/2023. I have an ER Lariat in Alaska. My dealer was sure I was the 4th delivered in the state. 2K miles with coldest days of -12F this season. 90% charge cap with preconditioning set to 15 minutes before I leave for the day with no issues. My truck has never been garaged. Preconditioning cannot be more strongly recommended for winter driving. It allows me to get through my ~60 mile daily commute always using less than 30kw. I’d use even less if I wasn’t coldsoaking at work where all their outlets intended for block heaters trip for faults. In days between 30-40F, I’ve been able to use as little ~21kw on my better days.
