What's wrong, in plain English
Tesla is recalling certain Model 3, Model S, and Model Y vehicles because of a software error. The error can cause a valve inside the heat pump to open when it shouldn't, which traps refrigerant inside the evaporator. When this happens, the vehicle's ability to defrost or defog the windshield is reduced. Vehicles with the problem no longer meet the federal safety standard for windshield defrosting and defogging systems.
What you should do
Where do I find my VIN, and what do I tell the dealer?
Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 22V050000.
