NHTSA Complaint #11446796 — 2021 TESLA MODEL Y

The heat stops working when the ambient temperature reaches 0 degrees. This is a safety risk in cold temperatures, especially for young children that can’t wear coats in the car due to car seats. This has happened in newer models that have a heat pump as the heating system, per social media accounts. The service center is inspecting tomorrow. A warning message appears when the heat stops working on the car screen. There is also an error on the phone app when preconditioning cannot start (preconditioning is supposed to mitigate the error, but it gets too cold to precondition).
