2018 Cadillac Ct6 problems
The Cadillac CT6 (short for Cadillac Touring 6) is a full-size luxury car manufactured by Cadillac between 2016 and 2020 over two generations. The first generation CT6 was introduced at the 2015 New York International Auto Show and went on sale in the U.S. in March 2016. It is the first car to adopt the brand's revised naming strategy, as well as the first rear-wheel drive full-size Cadillac sedan since the Fleetwood was discontinued in 1996.
In 2020, the CT6 was discontinued in the United States, to be replaced by the forthcoming Cadillac Celestiq liftback sedan.
First generation (2016)
The first-generation CT6 is built on a different platform than the smaller CTS and is engineered as a rear-wheel drive vehicle with optional all-wheel drive. In addition to its primary markets of North America and China, the CT6 was also offered in Europe, South Korea, Japan, and the Middle East.
General Motors discontinued the assembly of the Cadillac CT6 in the US in February 2020 due to poor sales and retooling of the Detroit/Hamtramck facility for electric vehicle production, beginning with the new GMC Hummer EV.

Hey there! Just a quick tip - it's always a good idea to get the price you're willing to pay in writing. If it seems too good to be true, it probably is!
-
It drives itself!
-
The CT6 has been fully redesigned to be very techie and easy to operate. The only downside is that the owner's manual can be a bit difficult to navigate due to somewhat lacking indexing.

This car is truly impressive! It offers a wide range of options that are not commonly found in other cars within its price range. The Super Cruise option is a game-changer, allowing for hands-free driving on divided highways. With a camera monitoring your eyes, you can stay aware of the road while enjoying a relaxing drive. The 4-Wheel Steering is another feature that sets this car apart, making it incredibly nimble and easy to maneuver. It even has Night Vision, which allows you to see beyond your headlights and detect obstacles before you even notice them. And let's not forget about the other amazing options, such as the panoramic sunroof, sunshades, multi-zone climate, massage seats, incredible sound system, self-parking, lane assist, and dual rearview mirror. This car truly has it all! The car works like a true mirror or operates using a rear-facing camera, all-wheel drive (in addition to the 4-wheel steering that turns all 4 wheels) and more. When you combine that with a quiet and smooth ride in a car that handles like a sports car, it's just an amazing car. One has to wonder why it was not promoted more?

The 2018 Cadillac CT6 plug-in has an impressive battery range of 40 miles, and when combined with a full tank of gas, it can exceed 500 miles - more than any current EV car! On battery power, it achieves an impressive 80-100 mpge, and on longer drives, it still manages an impressive 35 mpg at highway speeds and 40 mpg in the city when the 2.0T engine is fired up. I've personally driven over 1,500 miles without the gasoline engine firing up, making it a great option for daily commutes and errands. The CT6's long wheelbase makes for a smooth ride, although rougher surfaces can transmit through the aluminum and steel chassis. The seats are comfortable and wide, with good thigh support for longer legs. Plus, the heated and vented seats can be programmed to turn on every time the car is started. While some tech features like the rearview camera are mostly used in congested settings with limited distance viewing, the night vision works wonders in highlighting sidewalk walkers, and deer silhouettes are highlighted with a flashing display and vibrating seat, giving you plenty of time to slow down. The night vision even works in fog that the human eye cannot see! I purchased this 2018 model new in March 2020 for about half off the listed price, making it an incredible value for the middle $30s price range.

Garfield Cassin 2025-01-09
I had some concerns about the transmission when I purchased this car, but unfortunately, there were several other hidden issues that the dealer did not address before putting it up for sale. The car shakes quite badly due to all four wheels being bent, and I suspect that the shocks/struts are also bad. I did request that the mechanic drive the car to identify any issues, as I had to fly in to see the car before purchasing it. Although the sales manager did drive the car, he did not notice these issues. While the limited warranty is appreciated, I am a bit concerned about the distance between myself and the dealer. If necessary, I may have to drive the car back to have everything fixed, which would be a bit of an inconvenience. Despite these issues, I remain hopeful that everything will work out in the end.

I've owned four cars before my current one, including a Volkswagen Phaeton and three Hyundai Genesis models (2011, 2013, and 2015). I recently purchased a 3.6L Luxury Cadillac CT6 and have driven it for 2,000 miles. I was pleasantly surprised by how well it handles for a larger car. The steering is precise, making it easy to maneuver. The car is also very quiet and smooth, making for a serene driving experience. While it may not be as quiet as the Genesis G80 at higher speeds, it still meets my standards for a comfortable ride. I was initially hesitant to consider a Cadillac due to their reputation for being floaty and boat-like, but this car is anything but. I was won over by its safety features, quiet ride, and handling. Unfortunately, I have had some initial quality issues with the car, including the console cover falling off and a gouge in the right front wheel. However, these were minor issues that were quickly resolved under warranty. Overall, I am very happy with my purchase and would recommend the Cadillac CT6 to anyone looking for a comfortable and reliable car.It was replaced, but I had to go back to the dealer a second time because the air pressure monitor stopped working in that wheel after replacing it. When the car goes into 4-cylinder mode, there is a slight vibration that seems like either the timing is off a little or there is a torque converter shudder. It is almost imperceptible, but I can feel it. On the plus side, it doesn't go into 4-cylinder mode often. I find it hard to believe that Cadillac engineers designed it to drive that rough in 4-cylinder mode. My dealer doesn't feel it's out of spec. The driver's seat is squeaking. It normally doesn't start until I have a few miles in and the car is warmer, but it is getting increasingly bad. If I bounce my butt up and down, I can make it sound like a cheap motel bed. When driving, it is apparent when I hit a bump or corner. This just bugs me, and I am going to end up getting it fixed or shoot the car. I also think the dealer prep was lazy. I had to have them work on both my windshield and side view mirrors because of some kind of residue that made my windshield look sandblasted and the side view mirrors smudged and dirty-looking. I tried resolving these myself with window cleaner and scrubbing to no avail. I don't know what they used, but it's mostly okay now. I will say, once these issues are taken care of, I will absolutely love the car. But these niggling issues should not exist on a $65,000 car. That said, I love the drive, the quiet, and the value. Would I buy it again? At this price point, you aren't going to get another car that offers the quiet, size, comfort, and safety, combined with the precision steering on anything like this. In short, if I don't buy a Genesis G80 Sport, my next option would be this. For reference, I test drove Acura, Audi (I own an A5 Cabriolet), Volvo, Genesis G80 Sport, Kia Stinger (wife vetoed that one), Buick Regal Wagon, and Honda Accord.The Genesis falls a little short on interior materials compared to the Cadillac, but it has a better infotainment system and real knobs for the radio and A/C controls. At this point, I would call it a toss-up. However, if the Genesis had just a slightly better interior, it would have won out. UPDATE: Although more time has passed, I still regret to say that I am sorry I made the purchase. The car's 4-cylinder mode causes it to rumble, which is quite unpleasant. The dealer claims it's normal, but I disagree. Additionally, the driver's seat squeaks more and more as time goes on. I hope they will fix it. The infotainment system needs some tweaking, as the lack of buttons means there are always fingerprints all over the 10-inch screen. These things may seem small, but they matter when you are the owner and driving it, especially the seats and the rumble. I regret my purchase and should have bought a Genesis G80 Sport.

The transmission issue with my Cadillac CT6 has been a persistent problem, despite taking the vehicle in for service and receiving an upgrade to the computer. The hard shifting and lurching has occurred multiple times, even with my grandchildren in the car, which is concerning. It is clear from reading other reviews that this is not an isolated issue. While I understand that no vehicle is perfect, I am worried that this problem could lead to an accident or the need for a costly transmission replacement. Despite taking the car back to the dealership, they have been unable to duplicate the issue. However, every person who has ridden in my car has experienced the problem. Ultimately, GM repurchased the vehicle due to the transmission issue and their inability to resolve it.
Perry Trantow 2024-10-28
Hi there! I hope you're doing well. I wanted to let you know that I recently purchased a used Cadillac CT6 2017 on December 27th, 2023. Unfortunately, I've noticed that the transmission is slipping or shifting hard. Since the engine light has also come on, I plan on taking it back to the dealer to have it checked out. It's surprising to me that a car with less than 50,000 miles would have such a hard shift. Thanks for your help!
Gillian Deckow 2024-10-08
The ride quality of a Cadillac can be negatively impacted by the use of low profile tires. This was observed in both my 2013 XTS and the CT6, where the same type of low tire caused a bumpy ride and even resulted in expensive wheel damage after hitting a curb. It is unfortunate that the smooth ride that Cadillac is known for is being compromised due to the use of incorrect tire height.
