The Cadillac Celestiq started in 2024 and remains in production. Hand built Ultium flagship sedan produced in very low volume. Because that run covers more than one engineering generation in most cases, the single most important thing you can do before ordering is confirm which year you are working on. Parts that look interchangeable across a nameplate very often are not.
Battery pack configuration, charging hardware and drive unit layout change part numbers across trims and build dates on these vehicles. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed.
The parts we move most on the Cadillac Celestiq are cabin air filters, charge port components, coolant pumps and heat exchangers, 12 volt battery components and headlamp assemblies. On a electric vehicle these are the components where the difference between a factory part and a discount replacement shows up fastest, because they carry load, heat or both. Run your VIN before ordering. It takes a few seconds and it is the difference between installing the part and shipping it back.
We ship from Dallas, and in stock orders placed by 2pm Central usually go out the same business day. If you are working on something else in the lineup, our full Cadillac catalog covers the full catalog.
We specialize in GM vehicles that are 10 to 15 years old, and we often carry new-in-box parts for older models too. Discontinued parts are a normal part of the OEM business. When GM stops making a part and our stock is gone, that is the end of the line for that OEM part. We thank you in advance for understanding. The GM Parts Club advantage: our massive buying power lets us stock deep on the parts GM owners need, in our huge warehouse in Dallas, Texas.
