This is my second Cadillac XT 4 in two years and both have experienced the same thing. As I’m driving and come to a light to stop, the entire vehicle system gs black and cuts off. This has happened to me know 4 times, were the vehicle becomes disable in the middle of the road, during heavy traffic and almost hit several times from the rear. Each time I was in tears, thinking I was going to die and would call OnStar for assistance. The vehicle would not start, keep making this clicking sounds as if it’s trying. The vehicle would automatically go into ‘Park’ and will not release for any other gear. I was told the Fuel Management System, that I was told was not suppose to happen in the 2024 model like it did in my 2022 model. My app also reports a ‘Transmission System Failure’ for a brand new vehicle almost a year old & 7700 miles on it. I can’t deal with GMC & my life over their products. I want to get rid of the vehicle and never purchase another one of their products. Highly disappointed & the lack of concern from GMC about their customers.
