The power semiconductor components of the rear motor inverter of the vehicles within the scope of this recall may have slight manufacturing differences. After some vehicles have been used for a period of time, the manufacturing differences of the components may cause the rear inverter to malfunction, causing the inverter to fail to control the current normally. This fault occurs when the vehicle is parked, causing the vehicle to be unable to start; this fault occurs when the vehicle is in driving state, causing the vehicle to lose driving power. In extreme cases, it may increase the risk of vehicle collision and pose a safety hazard. According to information , Tesla has previously recalled its electric vehicles on a large scale many times .
