Component or System Failure: The HVAC system, specifically the compressor and supermanifold, failed on my 2020 Tesla Model Y. Tesla retained the replaced components during service, so they are not available for inspection. Safety Risk: This failure caused a loss of cabin heating and prevented proper windshield/window defrosting during cold weather, severely impairing visibility and creating unsafe driving conditions. Critically, this system also regulates battery heating. Without it, battery performance in cold temperatures can be compromised, reducing driving range, impairing charging capability, and risking vehicle operability in freezing conditions. Problem Confirmation: Tesla service technicians diagnosed and confirmed failure of the compressor and supermanifold. Full replacement was required to restore proper HVAC and battery heating functions. Inspections Conducted: The vehicle was inspected by Tesla service both before and after the failure. Prior to my ownership, the vehicle had been brought in by a family member (prior owner) for HVAC performance concerns....
