I have owned this car for a year now and i have to say i am truly impressed. I get more compliments on this car than any other car i have owned. This is my fifth car.I have had BMW 5 series and Mercedes S series drivers ask me about the CT6 at gas stations and at work. The acceleration of the 3.0 twin turbo is beyond impressive and the fuel economy is reasonable considering it is a 400 HP car. I have only taken the car on one long road trip to Nashville. After four hours of driving i did not want the trip to end. The car is that much of a joy. It feels much lighter than the 4100 pounds that it is. It is pretty nimble for a car it's size. After one year i have not had any unscheduled maintenance. The ride comfort is great and the rearview mirror that turns into a tv screen to show you the full rear view of the car is amazing! A must have on the highways. I have no regrets and i highly recommend this car. It is great to see GM back on track with some great products.

I love this car! It gets great on mileage, comfort and performance. The only issue I have had, and it is annoying, When it rains, there is a very small leak between the dash and driver's door. It has been in the shop four times and is now there for the fifth. The service advisor has always been very friendly and never questioned taking the car in. Right now, I am working with General Motors for their Buy Back Program. It's sticker price of my car to sticker price of a new one, less a usage fee. I'm sure the usage fee they will try and charge me will be huge, and I'll be very upset, we'll see. If so, this will be my last GM Vehicle. *** Update. GM actually came through with a VERY surprising usage fee. $400 for two years and 2 months of owning the car. I now have a brand new CT6. My only issue was that the selection of colors available to me was extremely limited due to having to select off my dealers lot. My color choice was red but, ended up with white.

So first off i had a 2001 Cadillac DTS, i completely loved that car!! after pushing it to over 250k miles i decided to sell it, but i had never liked the newer body Cadillac, so i've had a BMW 750 Li up until about May, when i decided even though i love the BMW im over the 13mpg and needed something better!! so i went to the Cadillac dealer and decided to get this cool batman looking vehicle with the pop up back tvs ect. Point is the car is gorgeous. But DAMMMMMMN ive never seen a "Luxury Car" who is so called trying to compete with the Lexus, Audi, BMW, and Mercedes!! this is by far THE CHEAPEST made vehicle i've even seen!!!!! i have 8,800 miles on the CT^ and i'm hearing noises, squeaks, oh and when i go over a bump, it sounds like the damn bottom is going to fall out! similar to when i'm driving my grand dad;s 1970 Buick!. I"ve owned both Inifiniti and BMW both with well over 170k miles! and never had to bring it to the dealers. Ive had this car for 6 months, and have been to get repairs 4x already. Everything is made of cheap plastic! i rented a 2017 Chevy impala on a vacation, and realized this car is the exact!! same thing, only with more hi tech features and fancier plastic!!! I highly suggest leasing this vehicle if interested!! so that way you wont get stuck regretting getting stuck in it.
Easily the best car I have ever owned

2017 Cadillac CT6 Platinum 4dr Sedan AWD (3.0L 6cyl Turbo 8A)
5 of 5 people found this review helpful
This is a very good handling car for how large it it. I have owned many (mostly German) luxury and sport sedans, but this one it the only one that does everything well. It is not the fanciest or most expensive I have owned, but the most well rounded. Please note that I own the Platinum which has a lot of suspension upgrades that make a difference! The braking is the best ever for a road car. The 4 wheel steering makes the car seem very small when driving. The suspension changes for every road condition and is VERY smooth and quiet. This car is quieter than any Lexus I have owned and steers better than any BMW I have owned. (Better feel than my M4 easily) It is also serene. No constant beeping at you like BMW. My one complaint is that the transmission at low speeds has occasional mildly hard shifts which should probably not be an issue for this price range.

When I bought this I expected transmission issues but there are a lot of hidden issues that the dealer should have been aware of and didn't address before they put the car up for sale. All four wheels are bent and need to be replaced because the car shakes very badly. I also think the shocks/struts are bad due to all the vibration. The sales manager did drive the car so he should have noticed it and had his shop look at the cause. The struts can cost up to $900 eack and the wheels from $300 to $500 on Ebay. I did request their mechanic drive the car and see what issues there would be because I had to fly in to see the car to buy it. I was hoping that the vibration was due to the tires needing to be balanced. This car does not cushion the road like the 2 others I had driven. My test drive was a bit short and not on a highway so most of these problems did not show up until my drive home. They did give my a limited warranty but at over 300 miles away I'm not sure how well that will work out. Worse case is I'll to drive it back and let them fix everything. That would cost around $500 for gas, tolls and an overnight stay at a hotel.
