Due to the possibility of losing power while driving, it may not start when parked, and tesla recalls nearly 130,000 Model 3s from today. The recall came after the State Administration for Market Regulation launched a defect investigation. Industry insiders believe that the Tesla stall problem previously exposed by some car owners may be related to the defects in this recall.

Effective immediately, Tesla will recall some of the Model 3s, both domestic and imported, produced between January 11, 2019 and January 25, 2022, totaling 127,000 units. The reason for the recall is that the motor inverter may fail, Zhang Xiang, dean of the New Energy Vehicle Technology Research Institute of Jiangxi New Energy Technology Vocational College, introduced:
Zhang Xiang: If the battery pack wants to provide energy to the motor, it must go through the inverter to turn the direct current into alternating current, if the performance of the power semiconductor in the inverter is unstable, it will cause the motor to have no electricity and the vehicle will lose power.

The announcement shows that the fault occurs when the vehicle cannot start when it is parked; the vehicle loses power when it is in the driving state. There have been many revelations of Stalls in Tesla driving, and recently a car owner was driving at a speed of 100 kilometers per hour in the tunnel, and the central control screen suddenly showed that "the vehicle cannot continue to drive." The owner changed two lanes in a row and stopped in the emergency lane without causing casualties. According to the State Administration for Market Regulation, the Tesla recall was carried out in the case of a defect investigation. Chang Yan, a well-known car blogger and founder of the supercharger station, introduced:
Chang Yan: If the State Administration for Market Regulation is highly concerned about this issue, it may be because it has been discovered in some landmark accidents. Therefore, there is reason to make a certain inference, if this situation has recently occurred, and it is exactly this part that is repaired, it is most likely caused by this defect.

In view of the above defects, Tesla will upgrade the motor control software for free through OTA (remote upgrade technology), closely monitor the inverter of the rear motor, and replace the failed rear inverter for free in time. In this regard, Zhang Xiang, dean of the New Energy Vehicle Technology Research Institute of Jiangxi New Energy Technology Vocational College, believes that:
Zhang Xiang: After all, this is a hardware failure, from the software can only be said to be a temporary measure, if you want to ensure 100% safety, or you need to take down the inverter in question and replace it with a new one.

The announcement shows that users should drive the vehicle cautiously before recalling the upgrade software. Liu Shi, a professor at the Beijing Police Academy, prompted that when a vehicle suddenly stalls, it is necessary to remain calm.
Liu Shi: Quickly turn on the double flashing hazard warning lights, when the light is not good or the haze weather, but also turn on the low beam lights, front and rear fog lights, so that the surrounding personnel and vehicles can see this abnormal situation. If the vehicle still has inertia, pull over as much as possible, and the highway will be evacuated to the outside of the protective steel plate, and the ordinary road will be a safe section beyond the shoulder of the road.

The reporter learned from many sources that Mercedes-Benz EQC and Xiaopeng Automobile in the domestic market have also been recalled because of similar inverter failures in the global market. Chang Yan, a well-known car blogger and founder of the supercharger station, introduced:
Chang Yan: There are often problems in small batches in the process of mass production of components, and the requirements for the manufacturer's adjustment and quality inspection department are very high. Second, everyone wants electric vehicles to have better power performance, are trying a variety of new power units or power components, may not have a particularly long-term verification of the components will enter the vehicle, resulting in failures and recalls.
