Defect description
Tesla, Inc. (Tesla) is recalling certain 2021-2022 Model 3, Model S, Model X, and 2020-2022 Model Y vehicles. 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."
Safety risk
Decreased defrosting performance may reduce the driver's visibility, increasing the risk of a crash.
Manufacturer remedy
Tesla will perform an over-the-air (OTA) software update, free of charge. Owner notification letters were mailed April 1, 2022. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-22-18-002.
