One problem related to software has been reported for the 2018 Tesla Model S. The most recently reported issues are listed below.
On at least 2 occasions, while driving the car, the electrical system stopped working. One time, the car just shut down at a stop sign nearby my office; the second time, while driving on the highway, the car continued to run but all of the other electrons: speedometer, turn signals, radio stopped working. When I pulled over, the entire car shut down. Both instances required a "hard stop" to re-start the car. The dealer informed me that this can happen when the software has not been recently updated. However, you need WI-fi to update the software and it is not readily available where I reside and park my car. I consider this situation extremely dangerous in that the car can spontaneously shut down while in use. I am taking the car into the dealer today-probably so they can upgrade the software on site. However, this does not address future potential issues with the car. I do not have the ability to routinely take the car into the dealership for upgrades. Further, there is no message from Tesla when the upgrades are available. Please help. I really have no desire to die when the car stops working while driving it!.
