My car while driving on the highway has turned off out of nowhere while driving 60 mph while the car is still moving I put the car in neutral turn the ignition off N then back and the car turns right back on but some days this happens more then others. This problem has been going on for several months I have been in and out of the dealership. And they still to this day can't tell me what is the problem. But I have done research and there a lot of these incidents going on with GMC vehicles idk why they say they can't find problem or fix it. They just want me driving on the highway with my family when the car stalls out. This problem isn't everyday it seems to happen 3-5 times a month. I don't remember the exact dates but this problem has been going on since I got the car. If the dealer can't tell me what's wrong what am I suppose to.
