Car will not respond for at least 2 seconds during a slow, rolling stop, when trying to accelerate again. Unable to perform evasive manuever, if needed, secondary to the delay to accelerator input. Harsh 2-1 downshifts also at slow speeds and can even feel as though you were struck from behind. Highway driving is excellent; city driving challenging with the transmission. The driver has to learn how to drive this vehicle. Find it very unusual after owning 5 other cadillacs and never had this problem. I bought this car as a pre-owned certified vehicle from Cadillac dealer. The car had 650 miles on it and I truly beatiful/showroom condition.

I am experiencing recurring transmission and drivability issues with my 2016 Cadillac CT6. 1.Rough Shifting: When shifting from park to reverse, the transmission shifts roughly, causing a noticeable jolt throughout the vehicle. 2.Fluid Leakage: I have observed fluid leaking from underneath the car when parked in my driveway. However, the leak is inconsistent—it disappears for a few days after rain or washing my driveway but then reappears under similar conditions. 3.Delayed Shifting: When accelerating from a stoplight, there is a delay before the transmission engages, causing hesitation before the car moves forward. 4.Automatic Start-Stop Issue: The vehicle has an automatic engine shut-off feature that activates when stopping at a light.
