Navigational (global Positioning System) Gps problems of the 2017 Chevrolet Volt

Like others, including the incident in rancho cucomonga, CA on the same day, April 25th, I was driving on the highway at high speed. I was in the carpool lane on the 210 freeway. I think I also was told to put the car in park. I lost the ability to accelerate on at a very dangerous time, while I was the furthest to the left in the late afternoon. Miraculously, there was only 1 car quite far behind me. So, after deceleration was forced upon my car, I began to steer the car to the right through 5 lanes - one of the widest parts of the highway at that point. Here is what I now think. I have been through loss of power in my 2014 Volt. I had accidentally turned it off while being on the highway. They fixed that design flaw in this 2017 model. I have shared my theory with gm. Gm/chevy has 3-way called me with the "stolen vehicles dept". They aggressively describe how they won't issue a slow-down through the on-star unless they have a request through police, the police are behind, the lights blink, etc. But, they're reluctant to share what happens next. They've been reluctant to share how they track your vehicle through the VIN and gps tracking. They're reluctant to share that this system can be hacked. It is evident that much can go wrong once the ability to control your car is placed in other's hands -- who aren't in the car driving it. The dealership could see the code of the slow-down. Of course they were surprised. This wasn't just a "failure". This is a "feature" in the car. . . But someone else used it without our permission. I want the on-star control disabled in my car!!! it could have killed my daughter and me. It could have killed the others who reported a similar situation.
