A retrofit program GM launched previously for vehicles built without functional park assist features, Customer Satisfaction Program N222375790, has been expanded to include more models, now including certain units of the 2022 Cadillac CT4 and the 2023 Cadillac CT4.
Additionally, the retrofit program now applies to the 2022 Cadillac CT4-V, the 2023 Cadillac CT4-V, and the 2022 Cadillac CT4-V Blackwing. The constraint on the park assist feature results from the microchip shortage.
For the Luxury trim level of the Cadillac CT4, the Rear Park Assist feature (RPO code UD7) was normally standard for both the 2022 and 2023 model years. Certain 2022 model year units of the Luxury trim were built without functional rear park assist between January 24th, 2022 and the end of the model year.
Turning to the 2023 Cadillac CT4, the constraint affected Luxury trim vehicles from start of production through September 2022. Units of both 2022 and 2023 CT4 Luxury trim level sedans built without this General Motors active safety feature have the RPO code 00Y printed on their window sticker for easy identification.
For the Premium Luxury trim and Sport trim of the standard Cadillac CT4, plus the CT4-V and CT4-V Blackwing, 2022 and 2023 model year vehicles are normally equipped with the Front and Rear Park Assist feature (RPO code UD5) as standard, rather than the rear park assist (UD7) found on the base Luxury trim.
During the 2022 model year of the CT4 Premium Luxury and Sport trims, and the CT4-V, certain units were built without front and rear park assist starting with January 24th, 2022 production and continuing until the end of the model year. For the 2022 CT4-V Blackwing the constraint on this feature affected vehicles produced between January 24th and April 10th, when the constraint was lifted.
For the 2023 model year the constraint affected the Cadillac CT4 Premium Luxury and Sport trims, and the CT4-V, between the start of regular production (SORP) and September 2022. The 2023 CT4-V Blackwing was unaffected by the constraint and built with functional front and rear park assist as normal. GM indicated affected units of all involved trim levels with a window sticker RPO code of 00Z.
Park assist availability was limited for other Cadillac models also. These include the Cadillac CT5, the CT5-V, the CT5-V Blackwing, and the Cadillac Escalade luxury SUV. The constraint varies between models and trim levels.
GM has instructed its dealerships to carry out the retrofit of the 2022 and 2023 Cadillac CT4 at no additional cost to the owner of the affected vehicle. The repair consists of replacement of the park assist control module and setup of the serial data gateway module to restore park assist. The program is in effect through July 31st, 2026.
Dealers informed buyers about the constraint and about GM plans for a future retrofit when the vehicle was bought. Owners of affected 2022 or 2023 Cadillac CT4 units can reach Cadillac customer service at the telephone below, referencing the customer satisfaction program number:
