Tesla, as the world's best-selling electric car brand, continues to achieve growth in sales, but at the same time, the problems of the brand model in the global market are also emerging, after several recalls. Recently, it has been exposed by the media that Tesla is carrying out maintenance work on a large number of Model 3 and Model Y models, specifically due to sensor failures on Tesla's model equipped with heat pump air conditioners.
According to foreign netizen green, because of air conditioning failure, Tesla needs to carry out a large number of "recalls" of 2020 and 2021 Model 3 and Model Y models with heat pump air conditioners. The three refrigerant pressure / temperature sensors in its heat pump air conditioners will fail with the passage of time. The solution is to replace the three sensors, and the replacement time is about 1.5 hours. In this regard, regardless of whether the vehicle has a fault or not, the sensor needs to be replaced.
It is worth noting that, according to this official document, all the models with problems are sold in all countries / regions, which means that the above problems will also be included in domestic models with heat pump air conditioners, Model 3max Y. Since the issue is not a safety issue, Tesla did not announce the recall.
In fact, since Tesla's Model 3 and Model Y models began to deliver new models, car owners have constantly reported Tesla's air-conditioning strike. Especially in the colder climate, the model is more prone to heat pump failure and can not work in extremely cold weather. It is reported that this kind of air conditioning problem of Tesla's vehicles often occurs in Tesla's service center in Quebec, Canada.
However, car owners who suffered from heat pump failure said that the problem could be solved through Tesla remote diagnosis and software updates. Therefore, there are industry insiders analysis, the recall of the upgrade project, is likely to be not limited to "air conditioning sensors" such as hardware replacement.
In fact, the new domestic Model 3 and Model Y vehicles are also equipped with heat pump air conditioners, but due to the very cold weather conditions are less, so far has not found a large number of heat pump failures. Only some car owners react to the problem that the heat pump air conditioner can not work properly. Car blogger "ForFun Sun Xiaozhe" posted on his Weibo that Tesla Model Y was charged and "the air conditioner was gone".
In January this year, the domestic Model Y model was brought to China, and Tesla Model 3 was revamped, among which Model 3 did not change much from the appearance of the old and new models, and only adjusted the appearance details and configuration of the model, including heat pump air conditioning (claimed to make the air conditioning system more efficient and reduce energy consumption, thus reducing the impact on driving mileage when heating in winter). Earlier, Musk proudly praised on Twitter: Model Y's heat pump is one of the best engineering designs I've seen in a while, so it's obviously a bit of a slap in the face.
Obviously, from the revelations of this foreign netizen, we can see that Tesla's handling of the heat pump problem has changed from "repair after customer complaint" to "recessive recall", which means that there is a risk of damage to the default air conditioning sensor. As for when to deal with it in China, we will continue to pay attention.
