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.

Common Cadillac Ct6 problems
The Cadillac CT6, a luxury sedan produced by General Motors, has been reported to have several common problems based on complaints from its owners. These problems span across various components of the vehicle, including the brakes and transmission.
One of the most critical issues reported is related to the brakes. The brake system in the CT6 has been found to struggle with proper operation, placing its owners and drivers at risk of accidents. Many CT6 owners have reported issues such as the brake system failing to engage, loud screeching sounds coming from the wheels, and the presence of a black greasy material on the wheels. In some cases, these problems have been attributed to faulty radial arms or brake shields. The brake problems in the CT6 have been significant enough to prompt a recall by General Motors due to software errors in the Electronic Brake Control Module (EBCM). This defect can cause the Electronic Stability Control (ESC) and Antilock Braking System (ABS) to malfunction, increasing the risk of accidents for drivers.
Transmission problems are another area of concern for CT6 owners. The 8L transmission in the 2017 CT6, in particular, has been criticized for its performance. Shift points can become corrupted, and shifts between gears can be violent, making the vehicle unpleasant to drive. Downshifts can also cause the vehicle to pulsate as it coasts to a stop. GM has released a fix for the transmission problem, which involves flushing the transmission and refilling it with new fluid.
In addition to these issues, the CT6 has also been reported to have problems with tire life and buggy electronics, which have been persistent issues in previous Cadillac models. The CT6's quality and reliability have generally received negative feedback, but perusing through forums reveals that the issues appear to be modest, particularly for the 2019-2020 model years. However, it is essential to note that the CT6 has had transmission problems in the 2016-2018 model years.
In summary, the Cadillac CT6 has been reported to have several common problems, including issues with the brakes and transmission. These problems have led to recalls and have been significant enough to affect the vehicle's overall reliability rating. Potential buyers should be aware of these issues and consider them when making a purchasing decision.
What problems are with the Cadillac CT6?
Summary: General Motors LLC (GM) is recalling certain 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 vehicles. Due to an Electronic Brake Control Module (EBCM) software error, the vehicle's Electronic Stability Control (ESC) and Antilock Brake System (ABS) may become disabled.
Is the Cadillac CT6 a good car?
Regardless of engine, the CT6 is hands down the most satisfying large sedan out there to drive, even if its actual performance numbers fall short of the competition's.
Is a Cadillac CT6 expensive to maintain?
A Cadillac CT6 will cost about $9,911 for maintenance and repairs during its first 10 years of service. This beats the industry average for luxury sedan models by $2,050. There is also a 27.02% chance that a CT6 will require a major repair during that time. This is 12.54% better than similar vehicles in this segment.
Which CT6 engine is best?
The engines of the CT6 get better, as you might expect, the higher their rated horsepower goes. That leaves the base turbocharged 2.0-liter four-cylinder as the least satisfying of the bunch and the twin-turbocharged V-8 as the best.

- Summary: Approximately in November 2022, I was driving my 2016 Cadillac CT6. While operating at a normal speed of 40 mph, while in traffic the vehicle began to hesitate and a loss of power. The vehicle was towed to Waldorf Cadillac & Chevrolet. The vehicle was diagnosed with a transfer case issue. The vehicle in the repair shop for approximately 4 months. I retrieve my vehicle in February 2023, with a brand-new Transfer Case with a price tag of $2,200.00. On Thursday, August 3, 2023, I managed to drive the vehicle back to Waldorf Cadillac & Chevrolet to have to vehicle repaired. The vehicle is doing the same thing it was doing , when the vehicle was previously in the Repair Shop. The Technician informed me that Cadillac recommend the fluid in the transmission be changed to a high-performance fluid. This recommendation was issued to the dealers several months ago. Now the dealer is charging me approximately $1,000.00 for Transmission Fluid. I asked the Technician why the problem wasn't corrected while previously in the shop. No reply. If Cadillac knows this is the problem, why is the customer being charged for this service, if this will correct the problem. There is 64,000 miles on my vehicle.

- Components: TIRES
- Summary: SIDEWALL CRACKING ISSUE WITH ALL FOR TIRES - PIRELLI P ZERO NERO 245/40/R20 While traveling out of town (Dallas to San Antonio) we experienced some tire issues which led to us needing to replace all 4 tires. Several weeks prior, we began to noticed a very slight loss of tire pressure and had the tires checked twice for any objects or other damage – Nothing found. We also had the tires rotated to trouble shoot and rule out any issues with sensors – none. Both times, the service shops did not mention or recognize any tire damage or issues. During our 5 hour drive to San Antonio, we started to see tire pressure issues again along with a noticeable sound from the tires. With this concern, we took vehicle to Firestone for diagnosis and to our surprise they found severe damage and cracks to the side walls of the tires. Firestone confirmed the tire damage was not safe to drive on and due to the location of the damages, we would need to replace all 4 tires. We were shocked to see such severe cracking damage and were at a loss for how this could occur. The tires were in very good condition and still had significant tire tread with even wear. After some research we discovered that this type of side wall tire cracking has been know to happen and even Pirelli has recalled tires for this issue. We did not see a specific recall to this size tire but did find that Pirelli had another recall on tires made in 2016 saying "THE PROBLEM WAS CAUSED BY A PRODUCTION ERROR (INCORRECT CARCASS COMPONENT), AND THE TIRES MAY SHOW SURFACE CRACKING IN THE LOWER SIDEWALL OF THE TIRE...". Please review this claim and confirm receipt. We are hoping to get some kind of reimbursement for the damages that we believe are a result of faulty or defective tires - this is what the Firestone technician also stated on video recording (I can provide video if needed).

Vehicle year: 2020
I've been driving Cadillacs for 30 years, and I must say, this is the best one yet! The ride is incredibly smooth and quiet, and the handling and acceleration are exceptional for a car of this size. The hybrids come fully equipped with so much high-tech equipment that it's hard to describe them all. I recently took it on a cross-country trip, and it was an absolute pleasure. Although I have noticed that at times, when quick acceleration is needed, the car hesitates before going. I have brought this to Cadillac's attention, but unfortunately, they have not yet addressed the issue.

I was looking for a large sedan that was both quick and athletic, without requiring frequent repairs. Additionally, I wanted a vehicle that had all the latest safety and convenience features, while still being reasonably priced. After reading magazine and owner reviews, I found that this car met all my requirements. Although I have only owned it for a month, I am already very satisfied with its performance in the areas I was interested in.

After driving a CTS-V for the past 4+ years, it was tough to leave that car for another. However, I chose the CT6 Platinum AWD 3.0TT for its improved features, AWD for inclement weather, and larger interior. It has every option imaginable and is an incredible everyday vehicle. Now that I have been driving it for 2.5 years, I can say without question that it is the very best automobile I have ever driven.

Vehicle year: 2020
After hearing and reading all the things people were saying about the CT6, I decided to buy one. It wasn't easy since many reviews were complaining about vibrations felt on the steering during acceleration and suspension not being smooth enough. However, after finally getting one, I can say that most of those reviews were just hating 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 an S550 AWD, and I felt the same thing when picking up speed under hard acceleration. Some reviews compared it to the Audi A6, which I had too. However, it was always at the dealer for problems with vibrations, electrical stuff, battery draining, trim on doors and pillars coming off, nav screen stopped working, and weird noises from the AWD system under hard accelerations and turning at low speeds. After just 16 months of ownership, I 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 months. 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, it was a 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. There was a lot of tire noise at highway speeds, and the seats were not comfortable at all. They were very hard. The rear seats were a little better, but still, for the price tag, there is no comparison.Some websites claim that the CT6 competition offers more technology and options, but that is simply not true. None of the models mentioned above have the same options as the Premium Luxury CT6, and even the top-of-the-line Lexus, Audi, or Mercedes models do not offer the same level of technology as the CT6. With features like Panaray Bose, Active Chassis and Steering, WiFi, Night Vision, and Super Cruise, the CT6 is truly exceptional. While there are a few flaws, such as the engine lacking horsepower and the transmission on the AWD model shifting hard at low speeds, overall the car is great. The start/stop technology can be annoying, and I believe luxury cars should not have this feature, or at least have the option to turn it off permanently. However, the car is perfect for carrying my three kids and is very safe, with all of the safety and driver awareness features working great. The heads-up display is excellent for seeing all the warnings, and the auto parking feature is cool and works perfectly. I love the night vision and the 360 cameras, which record any disturbance to the car and my trips. Overall, it's a great car, and I'm getting an average of 29.9 MPG, mostly on the highway.

This is a very nice vehicle, but unfortunately, it has a whining noise, especially between 30 and 40 miles per hour. The dealer has been unable to find the cause of the issue, and 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 rear drive shaft, and they have replaced the drive shaft three times, but the whine is beginning to start again. Since this is the third time they have been unable to fix the problem, GM has agreed to replace the vehicle, which also falls under the lemon law. We are hopeful that we can get them to give us a 2018 CT6. By the way, GM has informed us that this vehicle is only the third one in the entire CT6 fleet to have this problem. Lucky me, I guess!

I purchased a preowned certified 2017 Cadillac CT6, which is a lovely car. However, within two weeks of owning it, I noticed that the transmission was clanking and vibrating when shifting into a lower gear. Even my wife, who was sitting in the passenger seat, thought that the car was coming apart.

Hello! If you're considering purchasing a CT6, I wanted to share my experience with you. While I've owned 12 Cadillacs and was hoping the CT6 would be the new flagship of the Cadillac fleet, I unfortunately had some issues with my 2016 model. However, I'm happy to report that the 2019 CT6 is significantly better. GM upgraded the transmission and made some other improvements that have made a big difference. I've had no glitches yet and nearly all of the options function as they should. It's a very nice looking sedan. If you have any questions, feel free to ask!

My 2017 Cadillac CT-6 has unfortunately experienced some issues during the 20 weeks that I have owned it. Despite having to visit the shop for approximately 4 of those weeks, I remain confident in the car's potential. While there have been some challenges, such as the need to replace the brake pedal assembly and seat belt tightening motor, as well as a rattling noise in the headliner, I am optimistic that these issues can be resolved. I have brought the car to two dealerships for assistance, and while the issue with the headliner has not yet been resolved, I am hopeful that a solution can be found. Additionally, the brakes have been known to squeak intermittently, but I am confident that this issue can also be addressed. Overall, I believe that the Cadillac CT-6 is a great looking car with a lot of potential, and I am looking forward to enjoying it fully once these issues have been resolved.

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 am hopeful that everything will work out in the end.

Firstly, I had a 2001 Cadillac DTS which I absolutely loved! After driving it for over 250k miles, I decided to sell it. However, I was never a fan of the newer Cadillac models, so I switched to a BMW 750 Li until May when I realized that I was over the 13mpg and needed something more fuel-efficient. I went to the Cadillac dealer and found a cool batman-looking vehicle with pop-up back TVs, etc. The car is absolutely gorgeous! However, I have noticed a few issues with it. Despite being marketed as a luxury car that competes with Lexus, Audi, BMW, and Mercedes, it is by far the cheapest made vehicle I have ever seen. I have only driven 8,800 miles on the CT, and I am already hearing noises and squeaks. When I go over a bump, it sounds like the bottom is going to fall out, similar to my granddad's 1970 Buick! I have owned both Infiniti and BMW, both with well over 170k miles, and never had to bring them to the dealers. Unfortunately, I have had to bring this car in for repairs four times in the six months that I have owned it. Everything is made of cheap plastic! I rented a 2017 Chevy Impala on vacation and realized that it is the exact same thing, only with more hi-tech features and fancier plastic. If you are interested in this vehicle, I highly suggest leasing it so that you won't get stuck regretting your purchase.
