Cadillac Ct6 problems

cadillac logo

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.

  • 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.

The vehicle is doing the same thing it was doing , when the vehicle was previously in the Repair Shop.

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.

  • Date Complaint: 2023-07-06
  • VIN: 1G6KN5R61HU
  • 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).

    The 8 speed transmission on the CT6 could use some improvement. The first to second shift can feel jarring at times, and there are moments when it takes a few seconds for the car to shift from first to second, resulting in a temporary loss of power. Despite several complaints, GM and the dealerships have not yet addressed this issue. It's frustrating to experience this in a car that costs over $70,000.

    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.

    Vehicle year: 2020

    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!

  5. Clark Jakubowski 2025-02-19

    Vehicle year: 2017

    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.

    Beautiful styling, great ride, all sorts of electrical gadgets and innovation. I love the 360 overhead radar, side radar, and digital rear view mirror. It's always a pleasure to use it to take my BMW-owning friends to pick up their cars being repaired at the BMW dealer. They could have saved thousands by buying a Caddy instead!

  2. Fausto Hoeger 2025-04-13

    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!

  3. Abe Schuppe 2025-04-13

    Vehicle year: 2016

    I've owned my car for just over 4 years now and it has only clocked 26,000 miles so far. I didn't really need a new car, but my family was encouraging me to get one that reflected my financial circumstances. I sold my old car, a 2006 Buick Lucerne CXL with the Northstar V8, to a friend of my son's and it's still running well with 172,000 miles on it. However, I must admit that I'm starting to like my new CT6. It still turns heads and I got a great deal on a two-year-old car from the dealership. The performance of the TT 3.0 is exceptional and it's incredibly stable and quiet. Even my son was impressed when he drove it uphill and it went from 0-84 in the blink of an eye. The interior is beautifully done, but I do miss some of the practical features of older cars, like air vents that can be directed anywhere. The exterior styling is exceptional and I notice new details every day. People often stare at it when it goes by because it's longer than most cars. The trunk might be small, but it's more than adequate for 95% of my needs. I'm not very tech-savvy, but my sons loved all the electronics. Compared to other luxury cars like Mercedes or BMW, the CT6 offers great value for money. It cruises nicely on the highway and is perfect for executive commuting. The back seat has lots of room for passengers, although it's really designed for two people.I've grown accustomed to the stop-start technology, but for those who prefer not to use it, there is a button on the dash to turn it off. However, I did find that there are very few storage pockets for small items in the front. Overall, it's a great package and definitely worth considering if you're in the market for a car in this price range. I'm happy with my decision to purchase it, and I appreciate that it has retained about 60% of its value so far. While these higher priced car lines are not typically considered 'good investments,' they are certainly fun and safe to drive. I opted for the 10-year extended warranty, as I plan on keeping the car for at least that long. With only 40,000 of this model sold in total over 6 years (production ended last year and they won't be making any more here), it may become more difficult to find parts, but I trust that GM will honor their warranty. They could always source parts from China, where the car is still being sold. :)

    Your car is beautiful! I've had mine for almost three years and it's been everything I expected from a Cadillac - great style, comfort, and performance. The only issue I've had is that the transmission shifts very choppy. The dealer says it's operating as designed, but I'm not sure. Have you had any similar experiences?

    This car is amazing! It drives smoothly, quietly, and still has great acceleration. I am so pleased with the gas mileage, which is 28-29 in the metroplex. After a year of owning it, I can confidently say that this is the best car I have ever owned. On vacation trips, I have even gotten an impressive 33.4 mpg. Even after a year and a half, it still remains the best car I have ever owned. I am currently getting 28.5 mpg combined on premium and am seriously considering keeping this car for the long haul. In fact, I am even thinking about leasing a 2019 CT6 with supercruise once this one is paid off!
