This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs. Condition General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2021 model year Chevrolet Malibu and 2022 model year Chevrolet Blazer, Equinox, and Cadillac XT4 vehicles. The driver’s seat cushion frames in these vehicles may have an improper weld in the power tilt-adjustment mechanism. These improper welds may degrade management of occupant loads in certain crashes, which may increase the risk of injury for some occupants seated in the affected driver’s seats. Correction Dealers will inspect the driver’s seat and replace the cushion frame as necessary.

Important: Parts should only be ordered when inspection determines that it is necessary. It is estimated that there are only 245 involved vehicles that will require parts being replaced. Due to the small number of vehicles anticipated that will need this repair and the limited initial parts availability, dealers are encouraged not to order these parts for use as shelf stock. Reminder: Parts may be removed from Retail Inventory Management (RIM). Dealers should review the affected parts to confirm RIM managed status. Parts may have quantity limiters in effect.

Dealer Responsibility – For USA & Export (USA States, Territories, and Possessions) 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 under a sale or lease until the defect or noncompliance is remedied. The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time. Dealer Responsibility – All All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers’ possession and subject to this recall must be held and inspected/repaired per the service procedure of this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose. All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS system, or once again be used in the CTP program. Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter. Product Safety Recall N212356050 Driver Seat Improper Weld Page 7 of 9 In summary, whenever a vehicle subject to this field action enters your vehicle inventory you must take the steps necessary to ensure the program correction has been made before selling the vehicle. In addition, for vehicles entering your facility for service, you are required to ensure the customer is aware of the open field action and make every reasonable effort to implement the program correction as set forth in this bulletin prior to releasing the vehicle. Dealer Reports – For USA & Export For dealers with involved vehicles, a listing has been prepared and will be available through GM GlobalConnect Maxis Field Action Reports or sent directly to export dealers. The Inventory tab of the dealer reports will contain VINs that apply to this recall. This information is intended to assist dealers with the PROMPT COMPLETION of these vehicles. The Customer In-Service tab will contain customer names and addresses from Motor Vehicle Registration Records.

Production Dates : DEC 07, 2021 – DEC 07, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2021 model year Chevrolet Malibu and 2022 model year Chevrolet Blazer, Equinox, and Cadillac XT4 vehicles. The driver’s seat cushion frames in these vehicles may have an improper weld in the power tiltadjustment mechanism. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : These improper welds may degrade management of occupant loads in certain crashes, which may increase the risk of injury for some occupants seated in the affected driver’s seats. Description of the Cause : The seat-cushion frame supplier allowed excess weld debris to intermittently Part 573 Safety Recall Report 22V-359 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 build up in its welding fixture, which in rare cases can lead to improper welds. The supplier also failed to follow its standard process for inspection and containment of affected seat frames. Identification of Any Warning that can Occur : If the weld separates, the seat may feel loose or spongy, or may squeak. Involved Components : Component Name 1 : FRAME ASM-F/SEAT CUSH Component Description : Driver 6-Way Power Seat Frame Component Part Number : 13535244, 13535243, 13525370, 13525368, 13525388, 13513082 Supplier Identification : Component Manufacturer Name : Fisher Dynamics Address : 2301 St. George St. Evansville Indiana 47711 Country : United States Chronology : On December 7, 2021, a GM seat structure engineer submitted a report to GM’s Speak Up for Safety program after receiving a notice from GM’s final seat assembly supplier that a driver’s side seat cushion felt loose during the assembly process. Examination revealed a broken weld in the seat cushion frame’s power tilt-adjustment mechanism at the cross-tube / tilt-bracket interface. Inspection of 8,612 contained seats found three additional seats with improper welds at the same location. Based on a review of its production records, the seat-frame supplier determined that excess slag—a byproduct of the welding process—had intermittently accumulated in the welding fixture during the suspect period. Over time, this could, on rare occasions, cause the cross-tube to be improperly positioned with respect to the tilt bracket during welding. The seat-frame supplier had also failed to follow its standard process for inspecting and containing poor welds. Although the condition appeared to be extremely rare, and the supplier’s initial evaluation indicated that an improper weld would not pose a risk to the seat’s crash performance, out of an abundance of caution GM opened a formal investigation on January 25, 2022. GM conducted a series of computer simulations to assess the potential effect of a missing weld on crash performance in a variety of load cases. These simulations, completed on May 4, 2022, indicated that an affected seat would continue to conform to all applicable Federal Part 573 Safety Recall Report 22V-359 Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 Motor Vehicle Safety Standards, but might have degraded performance for 5th-percentile female drivers in certain crashes. In the course of the investigation, GM also retrieved and reviewed field data. This review, completed on March 22, 2022, identified no claims or complaints related to the subject condition. GM is also not aware of any associated accidents or injuries. On May12, 2022, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall. Description of Remedy : Description of Remedy Program : Dealers will inspect the driver’s seat and replace the cushion frame as necessary. Pursuant to 49 C.F.R. § 573.13(d)(1), all covered vehicles are under warranty, so reimbursement is not offered. How Remedy Component Differs from Recalled Component : Replacement seat frames were produced outside of the supplier’s suspect window. Identify How/When Recall Condition was Corrected in Production : Containment efforts were initiated on December 7, 2021. Vehicles produced after December 7, 2021 were built with confirmed seat frames or frames produced outside of the supplier’s suspect window. Improved inspection and detection measures were fully implemented by the seat frame supplier by January 31, 2022. Recall Schedule : Description of Recall Schedule : Dealers will be notified on May 19, 2022. GM estimates owner notification will begin on July 5, 2022. Planned Dealer Notification Date : MAY 19, 2022 – MAY 19, 2022 Planned Owner Notification Date : JUL 05, 2022 – JUL 05, 2022 * NR – Not Reported
