Tesla’s Heat Pump Issue Reaches China, as 26,000 Cars Recalled

After issuing recalls in the U.S. and other markets for software issues relating to the heat pump, Tesla has followed up with a new recall for its China-made vehicles.

Tesla has issued a recall notice applying to 26,047 Model 3/Y built at the automaker’s Shanghai Gigafactory, due to a software issue that may cause reduced heat pump and defrost performance, according to CnEVPost.

The recall covers 12,003 Model 3 units and 14,044 units, as published by the China State Administration for Market Regulation (SAMR).

In some of the vehicles involved in the recall, the heat pump’s expansion valve moves when positioned, causing the valve to open partially — and ultimately leading to a failure of the heat pump, as detailed in the announcement.

This causes the defrost function to stop working in many cold climates, and could significantly affect the driver’s visibility.

In order to fix the issue, Tesla will issue an over-the-air (OTA) software update, rather than asking customers to have their vehicles serviced.

Still, a few owners whose vehicles can’t be fixed through an OTA update may need to visit Tesla Service Centers, though the automaker will notify those to who this applies.

Transport Canada has issued a recall for the Tesla heat pump issue, as has the NHTSA in the USA.

In December, Tesla also recalled nearly 200,000 vehicles in China over problems with the vehicles’ trunks.
