Electrek points out this Fox 32 report from Monday showing Teslas that couldn’t charge in subzero temperatures, similar to issues some drivers reported last winter.

It’s unclear if drivers failed to warm the batteries by preconditioning (EVs in Norway, for example, seem to get by somehow) or if the chargers failed, and Tesla doesn’t respond to questions. Another report from WGN News points to long lines at functioning stations and includes a service center operator telling people to park their cars inside if possible.
