NHTSA Complaint #11524133 — 2020 GMC TERRAIN

This GMC I just purchased in October 22 2022 and have been complaining since December 9,2022 the vehicle emergency braking will activate when I'm driving down the interstate or local roads I could be doing 70 and brakes will just lock up throwing me and my son forward , this has happened 4x , Gas Pedal when taking off at red light or pulling out the vehicle is hesitant and will not go this has happened on 3 different occasions. I called roadside on star they said there is a problem with the on star saftey feature will not work properly this was towed 2x to different shops, Also while driving this vehicle it will just ingage itself in park while driving called on star they did diagnostic there was all kinds of Coded for Transmission and Engine as well as Emissions this vehicle is a safety hazard.. And I have tried to take back to dealership where I purchased they keep making excuses to not see this CPO with lifetime Warranty and still under warranty from GMC vechle Mileage was at 29k when problems stared vehicle only has 31k I can't drive this vehicle due to my son's and myself along with others saftey this is ridiculous and also GMC just informed me the Vin # they have for my vehicle and whats on it are two different numbers! Yet nothing is being done I'm paying for a vehicle that I can't drive I have proof GMC knows about the fraud from dealership but GMC says its a sales thing This vehicle has been flooded two mechanics have confirmed and GMC is aware so why not do something I don't know exactly the history and GMC doesn't either please someone contact me GMC this is crazy and you know it's a safety issue with this 2020 GMC Terrain you even said so
