GM Bulletin No.: 31770
Date: April 2016

SUBJECT: Service Update for Inventory and Customer Vehicles
Advanced Park Assist Operation Expires with Base Warranty

MODELS: 2016 Cadillac CTS-V


This bulletin provides a service procedure to reprogram the advanced parking assist control module on certain 2016 model year Cadillac CTS-V vehicles. These vehicles may park out of position when using the advanced park assist feature.

This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period.


All involved vehicles are identified by VIN in the Global Warranty Management System – Investigate Vehicle History Application. Dealership technicians should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.

Additionally, a list of involved vehicles currently in dealer inventory can be found in GlobalConnect, under Departments, Service, Field Action Inventory Reports (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty should also be checked for vehicle eligibility.
