The Cadillac Optiq started in 2025 and remains in production. Compact Ultium crossover positioned below the Lyriq. 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. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction.
The parts we move most on the Cadillac Optiq are charge port components, coolant pumps and heat exchangers, 12 volt battery components, headlamp assemblies and window regulators. 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. Send us your VIN before you order and our parts specialists will confirm the exact part number for your vehicle.
Orders placed by 2pm Central usually ship the same business day from our Dallas warehouse, which keeps transit times short across most of the country. 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.
