Affected by the extremely cold weather, the heat pump system of some Tesla electric vehicles has seriously failed recently, and Tesla owners have been troubled by the severe cold during driving < p > last year, Tesla Model 3 and model y electric vehicles had the problem of heat pump failure. Then Tesla claimed to solve this problem through remote wireless update, but it made a comeback this winter < p > at present, the temperature in Canada and the northern United States has hit a record low, and the temperature in some areas is even lower than minus 30 ℃ < p > many Tesla electric vehicle owners said that the interior heating system had the same problems as last year. Similarly, it seems that only Tesla Model 3 and model y models equipped with heat pump system are troubled by this problem < p > it is well known that the heat pump system cannot work normally in extremely cold environment (below minus 15 ℃) < p > Tesla claims that it has solved this problem with a dual cycle system, but it seems that there are other problems < p > however, several Tesla owners said that the system gave an alarm and there was no heat in the car < p > in cold winter, this may cause potential dangerous situations. Because some Tesla owners may be trapped in remote areas with extremely low temperatures and no heating < p > after the problem occurred, several Tesla owners who drove to Tesla service center were told that Tesla had found the problem and was repairing the software < p > Jimmy Yeung from Toronto, Canada, found the same problem with his model y. Tesla Service Center replaced the "eight way valve" components of on-board air conditioning compressor and heat pump system < p > Jimmy Yeung shared the bill of repairing Tesla cars out of his own pocket on Facebook. The bill shows that if Tesla is not under warranty, the owner will spend more than $4000 < p > Tesla also informed several model 3 and model y owners of heat pump problems that the problem may be very simple. For example, ice blocked the forward air port near the windshield, resulting in errors in the sensor of the heat pump system < p > the company recommends using the preheating function to thaw or manually remove the ice at the air inlet < p > Elon Musk, CEO of Tesla, previously said that the heat pump system equipped with model 3 and model y electric vehicles is "one of the best engineering examples he has seen in this time" < p > if your model 3 or model y electric vehicle is equipped with a heat pump system, Tesla owners should take this into account when making long-distance road trips in cold areas, because there is no heating in these places, which will bring real danger < p > Tesla had better find a fundamental solution soon. After all, it is too expensive to replace parts out of your own pocket for an insured vehicle < p > of course, people don't have to hold a negative attitude towards electric vehicles. Although the relevant Tesla cars are not heated, they can at least drive < p > many diesel locomotives have starting problems in extremely cold temperatures. In addition, this problem is limited to Tesla vehicles equipped with heat pumps. Tesla vehicles without heat pump system operate normally. (Chen Chen) < / P > < p >
