Tesla software error may cause a valve in the heat pump to open unintentionally and trap the refrigerant inside the evaporator, resulting in decreased defrosting performance.
The short version
Tesla, Inc. reported a problem with the electrical system software. Here is what owners need to know.
A software error may cause a valve in the heat pump to open unintentionally and trap the refrigerant inside the evaporator, resulting in decreased defrosting performance. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 103, "Windshield Defrosting and Defogging Systems."
Decreased defrosting performance may reduce the driver's visibility, increasing the risk of a crash.
Tesla will perform an over-the-air (OTA) software update, free of charge.
