Hate to spoil the anti cybertruck band wagon here, but apparently the owner discovered that they were doing something wrong. I think they seated the charger incorrectly, which allowed it to charge for a bit, but then the safety mechanism from the truck turns off the charging. These trucks and other electric vehicles can charge at this temperature range, but they will have reduced range.

Elon is still a Nazi, and these trucks look horrendous.
