The Cadillac CT4 is the luxury marque’s least expensive and least popular model currently on sale today, with the latter result being the result of various production issues and bottlenecks tracing their roots back to the COVID-19 pandemic. These supply line issues forced Cadillac to remove some options from the range, including the Onyx Package.
GM Authority has learned that the Onyx package is now available again to order for all trim levels of the “regular” CT4. Originally introduced for the 2022 Cadillac CT4, this package has been unavailable since March 2022, and the lack of availability continued into the 2023 Cadillac CT4. However, buyers can now option the luxury sedan with this dark-themed package once again.
The Onyx Package (RPO code PDB) is a dealer installed package that’s available across all “regular” Cadillac CT4 trim levels: Luxury, Premium Luxury and Sport. The package includes:
- 19-inch alloy wheels in a Gloss Black finish (LPO SOU)
- Gloss Black CT4 nameplate (LPO RIK)
- Black mirror caps (LPO 5JS)
- Black grille (LPO 5XR)
- Monochrome Cadillac emblems only on Luxury and Premium Luxury only (LPO SFZ)
- Gloss Black grille trim only on Sport (LPO E5K)
The Onyx Package is also available on the Cadillac CT4-V, however, the aforementioned parts constraint never affected this model, meaning that the 2022 CT4-V and 2023 CT4-V have always been able to be optioned with the package. The 2022 Cadillac CT4-V Blackwing is not available with the Onyx Package, instead relying on two Carbon Fiber Packages for (functional) visual appeal.
As a reminder, the Cadillac CT4 is equipped with either the turbocharged 2.0L I4 LSY gasoline engine, or the turbocharged 2.7L I4 L3B gasoline engine. Under the body panels is the GM Alpha 2 platform, while production takes place at the GM Lansing Grand River plant in Michigan.
