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 V…

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 t…
