NHTSA Complaint #11697463 — 2019 CHEVROLET TRAVERSE

I purchased a 2019 Chevy Traverse brand new off the lot as single owner and kept up with maintenance. The transmission just went out while I was on the highway and abruptly begin reducing speed and I was unable to accelerate. This was dangerous as no warning lights came on prior to this happening to warn that there were any engine issues. This could have caused an accident on the highway due to me not having control to accelerate and vehicle de-accelerated without warning. Also the passenger seat belt stop working and would not click. There was a Shift to Park warning that kept coming up on the car about 1.5 years ago that should be a recall as the car would not go off when turned off. The radio and lights in the vehicle would continue to run while the engine was off. I am concerned about all of the issue with this car that makes me question the quality and build of this vehicle. The first 4 years this vehicle was great and then all of a sudden it begin to breakdown in parts. The dealership confirmed all of these things and I asked if warranties were on these items and it was not.
