Almost a great choice for top luxury sedan

2017 Cadillac CT6 Premium Luxury 4dr Sedan AWD (3.6L 6cyl 8A)

After test driving a few of the 2017 CT6 models, I have concluded this is not the perfect car for me at this time. First of all, like many high end luxury vehicles, this car is air tight. Therefore, when all the windows are up, it is difficult to get the doors to close without slamming them. That's the reason why many of it's competitors went with automatic soft closures for the doors, like the trunk. Next, a rear wheel drive is not available with the 3.6L engine. Though I live in the snow belt next to one of the Great Lakes, I have never found the need for AWD as long as I use the right winter tires. I love the way rear wheel handles. I will never own FWD again, but would do an AWD as long as primary power comes from the rear. And, I won't be sold on a turbo charged 4 cylinder engine forced to work hard to act like a 6 or an 8. Besides, now you are stuck using premium fuel. Next, I dislike steering wheel paddle shifter's and want to do my manual shifting on the stick in the center console. And, I was hoping to be able to select something other than black for the dashboard and trim without having to move into the Platinum model. What with the rear camera mirror? It actually made me nauseous looking at it. Otherwise, it is a very good looking vehicle and would most likely own one if it at least had the door closures. I'm not going to slam doors on my vehicles. I liked many of the features like heads up display, start/stop technology and brake hold. With just a few more changes, I can see me behind a wheel of a CT6.

Not impressed with it

I currently drive a 2013 CTS and received a 2017 CT6 as a loaner car. Interior space is awful, I don't like the seat and I feel cramped inside. The roof is lower so my head is practically hitting the roof and I'm only 5'8. Overall, not impressed at all.

I bought a used Cadillac CT6 2017 on Dec 27th 2023; I have notice the slip or hard shift with the transmission. I will be taking it back to the dealer to get the car checked out Now the engine light is on, this car has less than 50,000 ml it shouldn't be a hard shift like this in this car.

2018 Cadillac CT6 Luxury 4dr Sedan AWD (3.6L 6cyl 8A)
1 of 1 people found this review helpful

GM (not just Cadillac) has a problem with its 8 speed transmissions up through 2018. Sometimes a flush with Mobil 1 (blue label) can take care of it. If not, then a replacement torque converter fixes the “shudder” problems. A spendy fix unless your powertrain warranty is still in effect. With its new torque converter our 2018 now runs like new again; with crisp handling, good response from the 3.6 liter engine and a very comfortable ride.
