What Problems Does the 2020 Cadillac CT6 Have?
Frequently reported problems for the 2020 Cadillac CT6, and earlier model years, often center around the infotainment system. Users have reported glitches, slow response times, and occasional system freezes. Some owners have experienced issues with the electronic parking brake. While not widespread, there have been reports of issues with the automatic transmission, specifically rough shifting or hesitation. The Super Cruise system, while innovative, has also been subject to occasional software-related errors.
Recalls for the CT6 have been issued for various reasons, including issues with the electronic stability control system, seat belt pretensioners, and brake systems. It's crucial to check the vehicle's VIN for any outstanding recalls before purchasing.
Long-term reliability is a concern for some, as Cadillac has historically not ranked at the top of reliability surveys. The complex technology and electronic systems in the CT6 can be potential sources of problems as the car ages. The discontinuation of the CT6 also raises questions about long-term parts availability and service support, although GM typically supports its vehicles for several years after production ends. Owners should prioritize regular maintenance and address any issues promptly to mitigate potential long-term reliability concerns.

How long will the 2020 Cadillac CT6 last?
With proper maintenance, a 2020 Cadillac CT6 can realistically provide 150,000 to 200,000 miles or 10-15 years of service. However, this relies heavily on diligent maintenance habits. Regular oil changes, timely fluid replacements, and proactive attention to any warning signs are critical.
Long-term durability concerns primarily revolve around the complex electronics and potential for expensive repairs. The suspension components, particularly the Magnetic Ride Control (if equipped), can be costly to replace. The interior materials should hold up well with proper care, but the infotainment screen and other electronic displays might show wear and tear over time. The 4.2L Blackwing engine is relatively new, so its long-term reliability is still being assessed.
