On April 29, for many people, their minds are no longer at work, they are in the company, and their hearts are on the way home. The day before the May Day holiday, when many people were ready to drive home, they may not know that Tesla and BYD issued a recall announcement. For fuel owners, it is forgotten after seeing it; for electric vehicle owners or people who are ready to start, a heart mentions the throat eye.
This month is Tesla's second recall, April 7 Tesla issued a recall announcement, due to the inverter quality defects, may lead to the vehicle can not start, or lose power in the driving, there are safety hazards; on April 29, Tesla again issued a recall announcement, the same Model 3, in the track mode, the speed value shows the missing speed unit, affecting the driver to make a correct judgment, there is a safety hazard.
The solution to both recalls is much the same, both through OTA technology. The lack of speed units seems to be an insurmountable problem, but in fact, the internal software is immature, or the probability of failure is relatively large. As we all know, electric vehicles lead the way in fuel vehicles with intelligent technology, basically presenting all vehicle information in digital form, which is also a major selling point.
Although this form is relatively advanced, I am afraid that it is easy to have problems. Take the model 3 this time the speed unit is missing, there will be no such low-level error in the fuel vehicle, which reflects the mechanical quality of the fuel vehicle or reliable than the electric vehicle.
I don't know if you found it, since there is an OTA, almost all the faults can be solved through the OTA, which seems to have become a shield for electric vehicle companies. Unlike before, we can see which parts have been replaced and repaired by the recalled vehicles, which can be seen and touched, and the heart is more solid. And now, whether it is a big problem or a small problem, the manufacturer said OTA, remote upgrade is finished. To tell the truth, a car of hundreds of thousands, remote tapping on the keyboard can solve the problem, although it is true, but the heart always feels that it is not that thing, not so down-to-earth.
The state seems to be aware of this problem, and on April 15, the Ministry of Industry and Information Technology issued a notice clearly stating that if car companies want to carry out OTAs, they must complete the filing of enterprise management capabilities, the filing of models and functions, and the filing of specific upgrade activities in turn before they can implement OTA upgrade activities.
To put it simply, when there is a quality problem with electric vehicles, OTAs are no longer so good at fooling consumers and are regulated.
BYD's achievements in the field of new energy, we are obvious to all, although sales are rising, a car is difficult to find, but also can not avoid quality problems. On April 29, BYD issued a recall announcement recalling some of the Tang DM models produced from September 2, 2021 to March 14, 2022, with a total of 9,663 units.
Reason for recall: Power battery pack tray Due to manufacturing reasons, the installation surface of the tray breathable valve is uneven and there is a risk of water ingress. This may cause the electrical circuit failure of the power battery system, and in extreme cases, there is a risk of thermal runaway of the power battery, and there is a safety hazard.
According to BYD's arguments, the reason for the spontaneous combustion of Tang DM is that there are process defects in the battery pack tray, not the problem of the blade battery. However, according to several recent Tang DM spontaneous combustion incidents, it has not been found that the vehicle spontaneous combustion caused by water ingress has not been found.
Take the most recent case, the owner picked up the car in December 2021, spontaneous combustion, and stopped at the 4S shop to wait for compensation opinions. The owner of the car said that the vehicle was in a state of shutdown at that time, not in the state of using the car, and the 4S shop also defaulted to spontaneous combustion caused by battery quality.
To be honest, the application of blade batteries has contributed a lot of sales to BYD. In the recall announcement, BYD did not mention the blade battery, attributing the problem to the battery pack tray. Taking the battery pack tray as a fig leaf on the surface is actually a problem with the battery, which is a matter of knowing it.
We often see this argument that an electric car driving for five years can save an English car. This statement only sees the advantages of saving money when using the car, and does not see a series of problems such as the discount of the winter endurance of electric vehicles, the high failure rate, the low guarantee rate and so on. This one-sided view can easily mislead consumers.
Conclusion: Model 3 and Tang DM are well-deserved benchmark products under Tesla and BYD, and it is indeed worth reflecting on car companies to have quality problems so frequently. Especially BYD, when the sales are in the sky, should pay more attention to quality, although the blade battery through the needle prick test, but from the current point of view, the spontaneous combustion rate has not been improved. It is hoped that BYD can face the problem head-on, communicate with consumers in a timely manner, accept consumer supervision and suggestions, and further improve the safety of blade batteries.
