NHTSA Complaint #11397138 — 2021 TESLA MODEL 3

HEAT NO LONGER WORKS IN THE CAR'S CLIMATE CONTROL. THIS APPARENTLY IS TIED TO FAULTY HUMIDITY AND TEMPERATURE SENSORS THAT MUST WORK PROPERLY FOR THE HEATING SYSTEM TO WORK, AND TESLA SERVICE CENTERS ARE AWARE OF THIS YET ARE NOT PROACTIVELY REPLACING THEM. THIS IS A SAFETY ISSUE IN COLD CLIMATES SINCE THE WINDSHIELD DEFROST NO LONGER WORKS, AND THE CAR IS UNSAFE TO DRIVE OVERALL IN COLD TEMPERATURES WITHOUT FUNCTIONAL HEAT. THIS ISSUE APPEARS TO BE RESTRICTED TO THE 2020/2021 MODEL 3/YS WITH THE HEAT PUMP THAT REQUIRE THESE SENSORS TO FUNCTION PROPERLY. ANOTHER SYMPTOM IS THE CLIMATE SCREEN DISPLAYS AN ERROR MESSAGE OF "CLIMATE KEEPER IS UNAVAILABLE DUE TO A SYSTEM FAULT."
