2019 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 2019 Cadillac Ct6 problems
The 2019 Cadillac CT6 has been reported to have several common problems based on complaints from owners. These issues primarily revolve around the transmission, brakes, and electronics of the vehicle.
Transmission problems are a significant concern for CT6 owners. Complaints include transmission delays, grinding or jumping when accelerating, and car shaking on the road. These issues can make the driving experience uncomfortable and potentially dangerous. The transmission problems have been severe enough that General Motors (GM) has issued a recall for certain 2019 CT6 vehicles due to software errors in the Electronic Brake Control Module (EBCM).
Brake problems are another area of concern for CT6 owners. The brake system in the CT6 has been reported to struggle to operate correctly, placing owners and drivers in danger of an accident. Complaints include the brake system failing to engage, loud screeching sounds coming from the wheels, and faulty front radial arms. The brake problems have been brought to the attention of GM, which has issued a brake recall to address the software errors in the EBCM.
Electronics issues have also been reported by CT6 owners. Complaints include the vehicle's sideview mirrors failing to automatically open and the brake booster failing, requiring replacement at just 1,800 miles. The brake system has also been reported to fail to engage while driving the CT6, increasing the risk of accidents for drivers.
Despite these problems, the CT6 is known for its spirited ride and quiet interior. The CT6 base engine is a turbocharged four-cylinder, but there is also a midlevel non-turbo V6 and a V8 version that both offer all-wheel drive as a standard feature.
In summary, the 2019 Cadillac CT6 has several common problems based on complaints from owners. These issues primarily revolve around the transmission, brakes, and electronics of the vehicle. While the CT6 is known for its spirited ride and quiet interior, the transmission, brake, and electronics issues can make the driving experience uncomfortable and potentially dangerous. GM has issued recalls to address some of these issues, but owners may still experience problems with their vehicles.

The CT 6 is a reliable car, but it can be quite expensive to own and operate. However, if you have the budget, this car will definitely satisfy your needs. It has a classic design with modern features that make it stand out from other cars on the road. If you're not a fan of flashy cars, the CT6 is perfect for you. It offers a luxurious driving experience that is unmatched. You won't be disappointed with this car.
-
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.
-
It sounds like you had a great experience with your Cadillac! I'm glad to hear that you found it comfortable and easy to handle, and the design is certainly beautiful. It's also impressive that you were able to get such good gas mileage on your recent trip - averaging a little over 28 mpg is really impressive. Thanks for sharing your thoughts!

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.

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

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.

Hello everyone, I wanted to share my first ever review with you all. I purchased a used 2017 Cadillac CT6 with 34k miles on it and drove it problem-free for about 3 months. However, after that, I started experiencing some noises and had to take it to the shop 4 times before they finally fixed some cover rattling on the catalytic converter. They ended up welding it instead of repairing it, which did the trick. Unfortunately, the fuel injectors went out and left me stranded. The last straw was when the car would jerk forward while in traffic. I eventually decided to trade it in for a Mercedes S550, which has been the best decision I've made when it comes to cars. I loved Cadillacs and had a DTS prior, but this experience has made me appreciate the importance of a reliable car. Thank you for listening.

I hope this message finds you well. I wanted to share my experience with the 2017 CT6 loaner car I received. While I appreciate the opportunity to try out a different vehicle, I found the interior space to be quite limited and the seat uncomfortable. As someone who is 5'8, I also noticed that the roof was lower and my head was almost touching it. Overall, I was not very impressed with the car. Thank you for your attention to this matter.

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!

I really like this car, but unfortunately, the air conditioner doesn't seem to work properly in Texas. Despite having it checked four times, the mechanics always tell me that there's nothing wrong with it. They suggested that I have the windows ceramic coated, but I'm not sure how that would help if the air conditioner is working correctly. When the car is parked outside while I visit my family, it takes about 30 minutes to cool down, and even then, it doesn't always cool down enough, especially for passengers in the backseat. I'm considering switching to a Mercedes as I've never had any problems with that brand.
