IT home January 15 news, Tesla's Model 3, Model Y electric vehicles, after exposing the problem of heat pump failure in the United States, a number of users complained that the car can not use heat pump heating in an extremely cold environment. Although Tesla previously updated the sensor with defects, some of the Model 3 and Model Y produced in 2020-2021 still have problems.

The reason for this problem is that the air inlet of the heat pump is frozen, resulting in abnormal sensor data and the entire system shut down. According to foreign media mspoweruser, Tesla today pushed the 2021.44.30.7 version OTA update for the vehicle, which solved this problem.
IT House understands that the changelog indicates that this version of the system allows the heat pump to start smoothly at lower temperatures. Users can turn on the vehicle's heating function to warm up 30-60 minutes before departure via the mobile app. However, if it is in an environment of -15 ° C, the heat pump heating may still fail. Tesla advises car owners to park their cars in warm places as much as possible to heat up the vehicle to solve this problem.
