Fighting with GM is not easy

m300michael, 11/14/2017
2017 Cadillac CT6 Premium Luxury 4dr Sedan AWD (3.0L 6cyl Turbo 8A)
I am having issue that involves the transmission on this vehicle. On occasion the transmission shifts/lurches so hard that it feels like the vehicle was struck from the rear. I did take the vehicle in for service and dealership stated that they upgraded the computer and the problem should not re-occur. Wrong! The same issue has occurred several more times and one time my grandkids … were in the vehicle and it actually scared them when the vehicle lurched. Reading other reviews involving the Cadillac CT6 shows that I am not alone with this issue. I know that there is no perfect vehicle available on this planet but, what I fear is that the lurching may occur and cause an accident or transmission will not last long and will need to be replaced (hopefully, while under warranty). This transmission issue is still an issue, as I have taken the vehicle back to the dealership and the dealership cannot "duplicate" the hard shift. Interesting fact is that every single person that has been in my vehicle has felt this problem and I have had it occur before and after taking the vehicle for service. No more review necessary. GM repurchased this vehicle as of 11/15/2018 due to the issue with the transmission and their inability to either replace or repair it.
