As GM expands Customer Satisfaction Program N222375791 to other models, those 2022 

and 2023 Buick Encore GX units built without a working Rear Park Assist feature 

 (RPO code UD7) are now undergoing retrofits enabling the functionality.

According to the service bulletin, the industry-wide semiconductor shortage

that followed COVID-19 caused the 2022 Buick Encore GX and 2023 Buick Encore GX crossovers

 to be constructed without the Rear Park Assist that they were supposed to feature.
