I have not been this excited about one of My Cadillacs since my first Northstar purchase in the late 1990s. I usually purchase used Cadillacs. I have had a 1976 Seville, 1997 SLS, 2000 STS, 2003 STS, 2007 STS AWD, 2013 XTS platinum. Most purchased three years old with low mileage. I now decided because of the Super Cruise feature to purchase New. I located the color, and model I wanted , drove 112 miles one way, and bought the White over Black CT6 platinum, I now own. I purchased it after a drive around the block. I traded my 2013 XTS platinum in, received 0% five year money, and drove home. 55 miles of which I went hands free, on super cruise. I have had Adaptive cruise for some time now, so I was used to everything, except letting go of the wheel. It was fantastic. The V-6 TT is right there as well. I have 1960s muscle cars that cannot beat it. I decided to drive the CT6 to my home in Louisiana 938 miles away from my usual residence. My wife, and I drove 600 miles the first day 85% of which was hands free. The whole round trip I drove hands free 1600 miles, Best 33 miles to a gallon, average 28. Through St louis in driving rain, and all. My wife said it beat every other Cadillac for front seat comfort. Finally the best massage in town on all four seats. I have peole at work that go out at lunch time just for that experience. The stereos have been so good for so long it is difficult to say, however the 34 speaker system , we love it as well. We both look very forward to the upcoming V-8 , I will opt for the 500 horse unit as I like the looks of that vehicle better. Thanks Cadillac for another great experience every time I decide to take this car. Did I forget to mention , It is fun again to take an automobile trip. Fun to drive 80 miles or so for dinner. Thanks Again. Ken Deill

I recently purchased my CT6 Sport after shopping for a month or so for a twin-turbo sport sedan. There was nothing within striking distance of the price of my car to be in the running. The technology packages on my car, with the added comfort and technology package, are outstanding. My favorite new piece of technology is the rear view mirror full-spectrum camera. Wow! This is the best safety feature since the blind-spot monitor. I never turn the camera back to its normal setting. This car handles beautifully. It’s acceleration in “touring” mode is smooth and amazingly quick. The car corners very well, which is amazing for its length. The entertainment and utility system is very easy to use and quite intuitive. I also love the built-in phone charger. Great idea! This is definitely not your grandfather’s Caddy. This Sport edition is a true head-turner. The aggressive body styling is very sharp. I look forward to driving my car every morning. If you love to drive an elegant, yet sporty, full-size sedan, take a look at this car. You won’t be sorry.

Absolutely the worse Cadillac I've owned

Buyer Beware. If you are committed to a CT6 insist that you road test your intended purchase for a few days before making the deal. First, I have owned 12 Cadillacs and was hoping that the CT6 was going to be the new flagship of the Cadillac fleet. It's not. . This disaster has the most crude, rough shifting 8 speed transmission that won't 'learn and adapt' and gets confused about which gear to crunch into. My CT6 has build-quality issues as my car needed to have its entire front end reassembled because of a mis-aligned fender that got crunched by the front door. My CT6 experienced a catastrophic rear axle hub/bearing failure in its first 200 miles. If you don't have access to German smooth autobahn pavement, stay away from the 20" wheels and magnetic suspension . . . the car will shake apart on normal roads. The AC is weak and has issues with the thermostat's control of its fan speed. Cheap hard plastic interior with a poorly designed center console featuring a useless cell phone charger. The rave reviews on-line must be based on quick test drives and photos of this otherwise nice looking sedan. Update August 2019: This one ended up in salvage/auction with less then 5000 troubled miles on it. A real mess. Fortunately, I can report that its replacement, a 2019 Cadillac CT6, is significantly better. GM upgraded the dreadful 8 speed transmission to a 10 speed and it actually shifts like any normal car. Nearly all of the options function and no glitches yet. Little tweaks here and there have improved it over the 2016-2018 versions of this model. It's a very nice looking sedan. Update March 2020: Replacement vehicle, 2019 CT6 is still performing well.

Easily the worst car I have ever owned

My 2017 Cadillac CT-6 is bad beyond belief. It has been in the shop for approx 4 of the 20 weeks that I have owned it. I would not wish this car on my worst enemy. Here is a list of all the problems. Brake pedal assembly needed to be replaced, seat belt tightening motor needed to be replaced, and panel under steering wheel fell off. Those are the problems that have been resolved. What has not been resolved is the headliner makes a loud rattling noise. It comes from the area between the sun roofs. I have taken it to two dealerships and they have attempted to fix it with “clamps”. That actually made it worse. Last but not least. The car makes a very loud whining noise. It sounds like a cat being tortured( not that I have heard a cat being tortured). It’s really loud. I understand that I may have just gotten a lemon but so far GM has not done anything to make this right. It’s a great looking car but so far miserable to drive. Update: the car still has all the original problems and has added a new one. The brakes squeak intermittently. Not right away but after driving for a little while. This happens every time I drive more that 5 miles. It appears to be a known issue for the year and make of car. So I bring it in to dealership and apparently they drove it around the lot once and since the brakes didn’t squeak they said there was nothing they could do. What a joke. The car and the Auto Nation Cadillac dealership in Wpb Fl are horrible.

After hearing and reading all the stuff people where saying about the CT6 I decided to buy one. It wasn't easy since a lot of reviews where complaining about "vibrations felt on steering during acceleration" to "Suspension not being smooth enough all kinds of stuff, after finally getting one I can say most of those reviews where just hatting on the CT6. There is some vibration felt under extreme acceleration but to anyone that has owned an AWD vehicle if you say you have never felt this you are lying they all do it, before getting this CT6 I had a S550 AWD same feeling when picking up speed under hard acceleration, some reviews compared it to the junk Audi A6, had one of those junks too always at dealer for problems with vibrations, electrical stuff battery use to drain, trim on doors and pillars coming off, nav screen stopped working and weird noises from AWD system under hard accelerations and or turning at low speeds, after just 16mo. of ownership decided to take it to the nearest carmax and get rid of it, not to mention the trade value on the A6 was less than 45% after 16 mo. : (.. The Benz was a lot better than Audi very smooth and not as much vibration, the only problem was the electronic suspension other than that great car. I test drove the Lexus and I can't believe why people make such a big deal about that car, the LS 500 felt like driving a Ford Econoline felt very heavy and not mannered at all during lane changes, lots of tire noise at highway speeds and seats are not comfortable at all they are very hard rear are a little better but still for the price tag there is no comparing. Some websites say "the CT6 competition Offers more technology and options" well thats a lie, none of the ones I mentioned above had any of the options the Premium Luxury CT6 offers and even if you get the top of the line Lexus, Audi or Mercedes you still don't get the same technology you get with the CT6, Panaray Bose, Active Chassis and steering, wifi , night vision and not to mention Supercruise the best. There are a few flaws to the CT6 1. Engine should have more HP, even though it gets up and going very well . 2. Transmission on AWD model shifts hard at low speeds sometimes, not all the time but I do have a lead foot. 3. Start / Stop Technology is annoying I think Luxury cars shouldn't have this period or at least a setting where you can turn it off period never to come on again at next ignition cycle. Other than that there is nothing at the time that bothers me, fits all the stuff I have to carry for my 3 kids , car is very safe all of the safety and driver awareness stuff works great, Heads up display is great you see all the warnings there , auto parking feature is cool and works perfect, love the night vision and the 360 cameras record any disturbance to the car and records you trips. Great Car Overall and so far it's been great, Getting an average of 29.9 MPG but I mostly do highway.
