I was driving the car all day and just had jumped back on highway doing around 65mph and all of a sudden the car threw itself into first gear it felt like and started accelerating on decelerating on its own jerking very violently if I wasn't wearing my seatbelt I would of went through the front windshield because it threw me forward i went from doing 65mph down to 10mph in less then 5seconds I was scared as [XXX] the steering wheel was hard to control and other cars were honking at me and it was just a mess and my car only has 100,763miles on it I barley drove it this year i will not get back in that car unless it is fixed because that's my daily driver and now its stuck in my driveway and my brother cant get his car out of the driveway so he's pissed now it wont go in reverse or wont move in neutral I left it alone I don't wanna mess with the car i already made a complaint to Cadillac and they said they will look into it and asked me for my vin but that was a few days ago they never called me or anything imagine if my nieces were in the car with me which I'm glad they Were not usually they are that [XXX] coulda killed someone and now I'm out of a car and there gonna look into it that's crazy they need to fix these cars transmission problems there having my car has never done this before and now I cant get to my job interviews because of this and still nothing is being done about it .
