Heres an example of it being claimed in the media that electromagnetic interference is causing Teslas to drive on their own without driver input. Case study of where this has been observed in other EVs posted below. Video of the Tesla driving itself is here. Incidentally i think that this happened to Ms Chaos Tesla. According to reports the Tesla was seen lurching forward several times before suddenly going into to reverse like seen in this incident. The difference being that this Tesla was already in motion when it glitched.

For an expert opinion, KXAN took the case to Dragan Djurdjanovic. A professor in mechanical engineering, Djurdjanovic looked into similar allegations against Tesla around 2008. The expert said it's very possible that electromagnetic interference between wires caused the accident.
Not only can low-frequency magnetic fields pose health hazards to human beings, but they can also affect some electric control units (ECUs) in a vehicle. An ECU that consists of Hall-effect sensors located near the battery pack or powertrain modules could be affected by the low-frequency magnetic field if no sufficient shielding is provided.
The electromagnetic interference affects the automobile electronic control system mainly in two ways: one is to affect the input signal of the sensor of the electronic control system, causing distortion and resulting in electric control signal where the ECU output does not match the driver's intention, which leads to the wrong operation of the actuator; the other is to interfere the ECU output signal to result in its deviation, misleading the operation of the actuator.
