Fighting with GM is not easy
I am having issue that involves the transmission on this vehicle. On occasion the transmission shifts/lurches so hard that it feels like the vehicle was struck from the rear. I did take the vehicle in for service and dealership stated that they upgraded the computer and the problem should not re-occur. Wrong! The same issue has occurred several more times and one time my grandkids were in the vehicle and it actually scared them when the vehicle lurched. Reading other reviews involving the Cadillac CT6 shows that I am not alone with this issue. I know that there is no perfect vehicle available on this planet but, what I fear is that the lurching may occur and cause an accident or transmission will not last long and will need to be replaced (hopefully, while under warranty). This transmission issue is still an issue, as I have taken the vehicle back to the dealership and the dealership cannot "duplicate" the hard shift. Interesting fact is that every single person that has been in my vehicle has felt this problem and I have had it occur before and after taking the vehicle for service. No more review necessary. GM repurchased this vehicle as of 11/15/2018 due to the issue with the transmission and their inability to either replace or repair it.

This would be the perfect car but ...
The 8 speed transmission on the CT6 is just plain awful. The first to second shift feels at times as if you have been hit from behind by another car. Other times it takes seconds for the car to shift from first to second and during that time the car has no power applied to the wheels. GM and the dealerships appear to do nothing about this after several complaints and tell me its normal (no...it's not normal for a $70+ car to shift like a 30 year old truck).

irritating whineing noise
This is a very nice vehicle but it has a whining noise, especially between 30 and 40 miles per hour. The dealer can't seem to find what is causing it. If they can't soon find a fix, we are considering if the dealer will buy it back. The dealer thinks the whine is coming from the rea drive shaft. They have replaced the drive shaft three times, and the whine is beginning to start again. Since this the third time they have been unable to fix the problem, GM said to replace the vehicle. It also falls into the lemon law. I hope we can get them to give us a 2018 CT6. By the way, GM says this vehicle is only the third one in the entire CT6 fleet to have this problem. Lucky me I guess.

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.

NO MORE LOW PROFILE TIRES!
My last Cadillac was a 2007 DTS luxury with the magnetic suspension . My new 2017 CT6 has the magnetic ride as well but with very little rubber between the road and the pretty 20" wheels you feel the bumps like never before. I kept the 2007 for a few weeks and can't believe how much difference in the smoothness of the ride the 2007 has over the new 2017 and have to believe these low profile tires with large wheels must make up the difference. As for warranty, I am pretty upset that you do not cover these wheels since they come with the upgrade package. I have a strong feeling the first large chuckhole I encounter will damage the tire and wheel. NOT GOOD BUISNESS for such a great expensive vehicle. By the way, this is my 5th Caddy. I love everything else about it, but I always bought for the smooth ride and this may lose my confidence.

Great but mind of it's own.
I have been driving Cadillacs for 30 yeas and this is the best one yet. You have to experience the ride to see how smooth and how quiet the car is. Handling, and acceleration are exceptional for a car this size. Because the hybrids come fully equipped their is more high tech equipment on bored than I can describe . It was a pleasure to take on a cross country trip. I say this car has a mind of it's own because at times when you need quick acceleration it will hesitate before going. I have brought it to Cadillac's attention, but they have not addressed the problem.

What I wanted.
I wanted a large sedan that was very quick and athletic (and didn't need a lot of down-time being repaired). I also wanted a vehicle that had all of the latest safety and convenience features and was reasonably priced. From the magazine and owner reviews that I read, this was the car. After only one month of ownership, I can not address the question of reliability, but I can attest to my satisfaction with regard to the other aspects in which I was interested.

Owners insight of Cadillac CT6 Plugin
Beautiful car with state of art technology and meaningful electric miles which make this full size sedan way above all competitors. Comparing this with Benz S class and BMW 7 is ridiculous since you are paying 40% less for a whole lot more. Over 2600 miles with level 2 charger at home and work my MPGe is currently at 129 and it is only going up.

Sharp classy luxury car
This was my first PHEV. Bought it new about 3.5 years ago. Very smooth handling. Plenty of power. It now has about 30k miles and still running well. Since we do alot of short trips, the 31 mile electric range is perfect. Have more electric miles will just mean paying for a lot more battery that I don't really need. We only get gas maybe 2 to 3 times a year! When we do get gas, we only get half a tank. Found out gas can get stale if left in the tank too long. Never had to worry about that before! Love the CT6 body design. To me, it is like a timeless classy design. It is unfortunate it is discontinued. The infotainment system is not very intuitive but the sound is good. You do need to be careful to make sure the hybrid battery coolant is above full. If it is at the full mark, which is the center seam line of the reservoir, there is a very small chance it can suck in some air bubbles then you end up getting a "service high voltage charging system". The car will not charge. You need to reset it with an OBDII scan tool then it will charge. Make sure you do have enough coolant. I'm guess GM made this extra sensitive since the Chevy Volt caught on fire in a parking lot after passing some crash tests. There is really no need to be that sensitive. That's about the only negative I have about the car. Ever since I kept it slightly above the full mark, I don't get the service high voltage system message anymore. Still using it everyday. Update. Have the car about 4.5 years. Still runs well. Almost never get gas. With gas prices going up, I'm even more happy we got this car. Never been much of an SUV or CUV fan. Sedans are always my favorite body style. Up-date. Have this car 5.5 years now. Bought it new back in 2017. Only had 1 issue. The high voltage battery coolant sensor failed. I was expecting that since it is the same as the Chevy Volt. However, unlike the volt, the sensor is behind the backseat and trunk. Only way to get to it is to remove the backseat, side panels and rear panels. Decided to let the dealer do that. No other issues after that. Car still drives smooth and handles well. Love large sedans as it can fit 5 comfortably with style. Still only get gas (half tank) every 6 months just so the gas won't get stale. We have solar panels and a level 2 charger at home so charging the car every night is not an issue.

Welcome back GM!
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.

Leaky Luxury
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.

They should call this car the Chevy Impala Luxury!
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
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.

This car is made for driving!
Anyone that has driven a full-size luxury car needs to drive this one. The only word that comes to mind is “nimble”. This car is bigger than it’s European competition, thousands cheaper than the competition, and nimble. AWD Is now something I can no longer live without, and that clunk people complain about is just the transmission engaging all the wheels, and if you’re not used to that it seems like somethings wrong. There ain’t nothing wrong, you just have to get used to flinging around Cadillac’s flagship. The V-6 is plenty powerful enough, and good on gas mileage. This car is the same weight as my 2012 CTS was. Just keep one thing in mind when you drive this car, this is a big-Ass car!

Money pit CT6
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.

Most Fun Car Ever
If you have never owned a luxury sedan - give yourself a month to learn about the features , where they are and how to program them. I transferred from a Cadillac XTS to my CT 6 so my learning curve was much shorter but the surround vision was great, USB and Hot spot features take some getting used to, ONSTAR uses the built in Navigation system - you need to understand the interface features between Onstar and the onboard Navigation system - the one feature that is confusing is the memory setting from your remote key bob - they are not numbered anymore for some reason so you can confuse the memory setting for the seats and mirrors if you transfer remote keys - this is the one feature you should have the dealer explain before you drive your car away - it will save time later. Other than that - curl up with the instructions books and enjoy. After more than a year - I would add that the Premium Red car color is great as well - My car is outside 24/7 and looks clean all the time except during pollen season :) Now 3 years in and I still love the car but will be replacing it with a 2020 Lexus LS 500 F Sport next week. I wanted to upgrade my car to a Double Turbo CT 6 Sport Premium Luxury but GM discontinued that engine and car and essentially discontinued me after driving Cadillac's since 2006

Great Car but Transmission is an issue
i bought this preowned certified 2017 Cadillac CT 6. Lovely car but two weeks after i got it transmission is like clanking and vibrates when it goes into a lower gear. My wife was in the passenger seat and thought the car was coming apart.

OLD GRAY MAYER AINT WHAT SHE USED tO BE
Ride is awful for a Caddy. Low profile tires is the culprit. hit a curb, no tire scrape just grinding of the very expensive wheel. It happened with my 2013 XTS and the CT6 with same type of low tire will cause the same problem in addition to causing a bumpy ride. The smoooth Caddy ride generated a lofty reputation. It is sad that it is being abandoned due to wrong tire height is being used.

A/C not good
I like this car a lot, but in Texas the air conditioner just doesn't work. I have had it in the shop four times and they always tell me there's nothing wrong with the air conditioner......and then they say that I need to have the windows ceramic coated. Soooo, if it works correctly why would I need coating? If it sits outside while I am visiting my family, it takes about 30 minutes to cool down, and usually it never cools down enough especially for people in the backseat. I think I will go to Mercedes next as I never had a problem with that brand.

Keep auto stop turned off as well as cruise control when driving in stop start traffic you will not have any trouble.I have over one hundred thousand miles driving in snow in Canada with normal tires ct6 all wheel drive

Not the old man's caddy
I test drove the NA V6 with standard suspension and 19" wheels. Found it very composed, offering a nice ride on smaller bumps, as well as very solid high merging acceleration. Seats comfy during test drive, and CUE system worked fine for the limited amount I used it. Felt the transmission shifted nicely and kicked down quickly for acceleration, though noted that the car was in sport setting. Wife claimed she couldn't quite get comfy in the driver seat, though she didn't spend that much time adjusting it. Overall, I though the chassis felt nicer than the E400 wagon i had just test driven, though not as fast. The Merc was more luxurious inside, but I was not disappointed in the CT6. Didn't get a chance to really lean on the car, but my test drive was enough to convince me that I should spend more time in one, and that it is still on the list of possible candidates.

Almost a great choice for top luxury sedan
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.

2017 Cadillac Ct6 on Vogues nightmares.
Hey guys, my first review ever but i had 2 share. I bought a 2017 cadillac ct6 used 34k on the dash. Drove it problem free for about 3 months. Then the noises started happening. Had 2 take it 4 times for them to finally fix some cover rattling on the catalytic converter. They said they welded it vs repairing it. Fixed that finally. Then the fuel injectors out. That left me stranded. The last straw was when thr car would jerk forward while in traffic. Traded it for the Mercedes S550. So far the best decision ive made as far as cars go. Loved Cadillacs had a Dts prior. Thanks for listening.
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.

almost perfect
This is my 5th Caddy and it doesn't disappoint. The transmission is the vehicle's only flaw. Hard shifts ruin an otherwise perfect experience. Working with a dealer to repair this concern but based on the other reviews, I have little confidence.

Not happy Mel
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.
