Musk said Tesla will release new software to fix the heat pump problem

According to foreign media reports, Tesla CEO Elon Musk announced that the company will release software updates through OTAs to "solve" the heat pump problem, which has been plaguing Tesla owners from cold regions. However, there has been speculation that software alone will not solve this problem, because Tesla service centers have hinted to some car owners that the heat pump problem comes from hardware, not software.

Last week, some media reported that in extremely cold weather, tesla cars' human pumps will fail, resulting in the heating function can not be used. The problem first arose last winter, focusing on models equipped with new heat pump systems. This system was first used on the Model Y and then on the latest version of the Model 3. Tesla said at the time it had solved the problem with a software upgrade, but the vehicles encountered the same problem again this winter.

Musk said fixing the problem is their current "top priority" within Tesla, and over the past weekend, he announced that Tesla would fix the problem by releasing new software. "The repair firmware for recalibrating the heat pump expansion valve is now available," he says. ”

Many Tesla owners, who said their vehicles lost their heating function in extremely cold weather, drove them to a service center and then replaced the entire heat pump system for the vehicle. A Tesla service center staff explained the problem to the owner, saying that the heat pump inlet has a "baffle", or a valve, which will freeze in extremely cold weather. The service staff told the owner that this was a hardware problem. Therefore, it has been suspected that software updates will not completely solve this problem. Previously, both the National Highway Traffic Safety Administration (NTHSA) and Transport Canada announced that they had launched an investigation into the issue.
