GLOBAL SAFETY FIELD INVESTIGATIONS DCS6350 URGENT – DISTRIBUTE IMMEDIATELY Date: November 23, 2022 Subject: Stop Delivery Order for Upcoming Safety Recall N222373320 Rear View Camera Intermittent or Inoperative Models: 2019-2020 Cadillac XT4 Equipped with VISION-360 VIEW, MONO, HD DIGITAL (UV2) To: All General Motors Dealers STOP DELIVERY ORDER Effective immediately, stop the delivery of certain 2019-2020 model year Cadillac XT4 vehicles in new or used vehicle inventory. General Motors has notified the National Highway Traffic Safety Administration (NHTSA) about an upcoming safety recall that involves these vehicles. The GM recall number is N222373320. It is a violation of federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification until the defect or noncompliance is remedied. The rear-view camera (RVC) in these vehicles may fail or function intermittently. If the rear-view camera is not functioning properly, rear visibility is reduced, increasing the risk of a crash during a backing event. Parts are not currently available, but when parts are available, dealers are to update video processing module (VPM) software. For 2019 model year vehicles, this will also require replacement of the VPM. Until further instructions are received, involved vehicles that are in dealers’ possession (new or used vehicle inventory, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc.) must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration purposes or any other dealer use. All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified. The Investigate Vehicle History (IVH) screen in the Global Warranty Management (GWM) system will be updated for this upcoming recall on November 23, 2022. This action has been taken to assist dealers with determining which vehicles are involved so they can properly respond to customer inquiries. A Stock VIN list is not included as our records show there are no vehicles in dealer new inventory. To identify involved vehicles in dealer used inventory, run an Open VIN Report or Field Action Initiation Report using Field Action Reports-GFAM within the Maxis Dealer Application in GlobalConnect. Question and Answer Document (Q&A) Attached to this message you will find a document that addresses the ten most likely questions customers may have regarding this Safety Recall. Please use this information as an aid to confidently answer customer concerns. Until the recall bulletin is released, the Investigate Vehicle History (IVH) screen in the Global Warranty Management (GWM) system will display “11/23/2022” under Release Date and “Incomplete – Remedy Not Available” under Status. This means the required repair is not yet available and dealers should not attempt to perform any repairs. We are working to develop a remedy as quickly as possible. When a remedy is available, the recall bulletin will be released and dealers can begin repairing vehicles. END OF MESSAGE GLOBAL SAFETY FIELD INVESTIGATIONS

GM CUSTOMER CARE AND AFTERSALES DCS6360 URGENT – DISTRIBUTE IMMEDIATELY Date: December 8, 2022 Subject: N222373320 – Safety Recall Rear View Camera Intermittent or Inoperative Application for Used Vehicle Working Capital Assistance Program (WCAP) Models: 2019 – 2020 Cadillac XT4 Equipped with VISION-360 VIEW, MONO, HD DIGITAL (RPO UV2) To: All General Motors Dealers On November 23, 2022, GM sent to all GM dealers GlobalConnect Message GCUS-3-2713 regarding safety recall N222373320. The required repair to complete this recall is not yet available. Until further instructions are received, the involved vehicles that are in dealers’ possession (new or used vehicle inventory, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc.) must be held and cannot be delivered to customers, dealer-traded, released to auction, used for demonstration purposes or put to any other use. This message is to inform dealers who have involved vehicles in their inventory that they can now apply for the used vehicle Working Capital Assistance Program (“WCAP”) for safety recall N222373320. Before proceeding with the application process described below, dealers must verify vehicle eligibility based on the program terms and guidelines that were provided in GM GlobalConnect Message GCUS-9-10968 dated March 10, 2021. Applications submitted on ineligible vehicles are subject to chargeback of any incentives paid to the dealer under the WCAP. Because compensation and tracking requires visibility into dealers’ inventory, dealers must also have agreed to a Dealer Data Share agreement with GM in order to receive any compensation under this program. To apply for the WCAP for safety recall N222373320, dealers must access the GM Global Warranty Management (GWM) system and submit a “ZSET” warranty transaction using the labor code provided below for each eligible vehicle. This zero dollar special transaction type is the dealer’s application for compensation and constitutes a representation from the dealer that the vehicle is eligible for WCAP assistance. Note: Acceptance of the warranty transaction does not ensure vehicle eligibility or guarantee the provision of any assistance as defined by program terms and guidelines. Labor Code Description Labor Time Trans Code 9800100 Working Capital Assistance for Safety Recall N222373320 N/A ZSET To be eligible for the WCAP, a vehicle must be in dealer inventory at the time the related field action bulletin is released. If a vehicle has been delivered, wholesaled or otherwise disposed of prior to release of the bulletin, the vehicle is not eligible for assistance. Additionally, recalled vehicles taken in on trade may be eligible for assistance if the dealer immediately reports the vehicle in used vehicle inventory via its Dealer Management System (DMS) and makes application through the GWM system. To ensure that GM is receiving daily inventory information, which is necessary to process payments and make eligibility determinations under the WCAP, the dealer’s vehicles must be properly identified in the dealership’s DMS. A daily feed of this information is provided to GM through the Dealer Data Share (DDS) agreement. Beginning with the 1st quarter of 2019, all WCAP payments will be facilitated through the Global Warranty Management (GWM) system. For each eligible vehicle, a qualifying dealer will submit for WCAP vehicle enrollment with a “ZSET” transaction type and for reimbursement with a “ZFAT” transaction type both through the GWM system. If approved, a WCAP credit for that vehicle will be issued through the GWM system similar to any other warranty credit. WCAP submission instructions and the required labor code will also be provided in the appropriate field action bulletin. Each WCAP transaction being credited will be clearly identified on the dealer’s daily credit memo. In order to receive payment, a dealer must have timely reported the vehicle in used vehicle inventory, retained the vehicle until the related field action bulletin is released, and properly applied for the WCAP payment. The vehicle must also be otherwise eligible under WCAP rules and guidelines. GM reserves the right to amend, modify, terminate, or cancel this program at any time in its sole discretion.
