A few days ago, some netizens broke the news that they were driving a Model 3 in the tunnel and encountered an emergency situation in which the vehicle suddenly lost power. From the owner's revelations, it can be seen that this Model 3 was just mentioned on New Year's Day this year, and in the process of using the car in normal times, it will often "appear for no reason, it will run after locking the car, the car will make a rumbling sound, and reopening the door and closing it again will not be there."
The owner of the car said that when the situation occurred, it was driving normally at a speed of 100 yards in the tunnel, suddenly without warning, the screen showed "the vehicle can not continue to drive, please stop immediately", because there is a car following behind, the driver stepped on the electric door deeply, but the car did not respond. According to his own account, he reacted for 0.5 seconds, immediately hit a double flash, and changed two lanes in a row, and finally stopped in the emergency lane, because he completely lost power, and the body only went in halfway.
Immediately after the accident, the owner contacted Tesla's sales and was told that they had not encountered such a situation. It is recommended that it connect to the after-sales, after-sales still said that there is no solution, and asked the owner to call the trailer by himself. Subsequently, the vehicle was pulled to the Tess Aftermarket Processing Center, where, based on the latest developments in the incident, the vehicle fault code was pointed to the rear motor inverter power semiconductor components.
On the afternoon of April 7, Tesla filed a recall plan with the State Administration for Market Regulations in accordance with the requirements of the Regulations on the Administration of the Recall of Defective Automobile Products and the Implementation Measures for the Regulations on the Administration of the Recall of Defective Automobile Products: from April 7, Tesla will recall some imported and domestic Model 3 electric vehicles with production dates from January 11, 2019 to January 25, 2022, with a total of 127785 (including 34,207 imported Model 3 vehicles and domesticAlly produced Models). 3 cars 93578).
There may be minor manufacturing differences in the rear motor inverter power semiconductor components of vehicles within the scope of this recall, and the component manufacturing differences after some vehicles have been used for a period of time may cause the rear inverter to fail, resulting in the inverter not being able to control the current normally. This failure occurs when the vehicle is in a parked state, which will cause the vehicle to fail to start; this failure occurs when the vehicle is in a driving state, which will cause the vehicle to lose driving power, and in extreme cases, it may increase the risk of collision of the vehicle, and there is a safety hazard.
Tesla Motors (Beijing) Co., Ltd. and Tesla (Shanghai) Co., Ltd. will upgrade the motor control software for vehicles within the scope of the recall free of charge through the vehicle remote upgrade (OTA) technology; for vehicles that cannot be recalled through the vehicle remote upgrade (OTA) technology, they will contact relevant users through the service center to upgrade the motor control software for the vehicle to closely monitor the rear motor inverter of the vehicle, and timely replace the rear inverter with related failures free of charge to eliminate safety hazards.
We will continue to pay attention to this incident and hope that the Model 3 owners within the scope of the recall will contact the Tesla service center in time.
