In the cold winter season, some Tesla models could not defog the windows normally, so Tesla "welded" a new large-scale recall. But as before, Tesla can still use "online recalls" to deal with these glitches.

　　On February 18, we learned from the official website of the State Administration for Market Regulation that Tesla submitted a filing in accordance with relevant regulations and will recall some Model 3 (12,003 vehicles) produced between December 28, 2020 and January 15, 2022. ) and Model Y (14,044), for a total of 26,047.

　　■ What's wrong?

　　Among the 26,047 vehicles recalled this time, the heat pump electronic expansion valve will move slightly when it is positioned, but the software (version 2021.44 to 2021.44.30.6) has no corrective function. Long-term use may cause the valve to partially open and the heat pump compressor to stop working, resulting in The heating function in the car has failed.

　　Especially when the temperature outside the car is lower than -10°C, when the windshield defrosting system is running, this part of the vehicle cannot achieve the defrosting effect stipulated by the relevant national regulations (nor can it meet the owner's normal car needs...) , which can adversely affect the driver's field of vision, thereby increasing the risk of a collision.

　　According to the current regulations, car companies have no right to perform OTA upgrades on vehicles without permission, and all OTA upgrades need to be filed. If it was 2 years ago, Tesla seemed to be able to quietly deal with these problems through OTA, but under the pressure of new regulations, Tesla needs to be more careful and focused on handling system failures, which also profoundly reflects the new meaning of regulations.
