• • • • • MAZDA D A ER MAIL January 4, 2022 Attention: Mazda General, Parts and Service Managers Subject: Preliminary Notification to Owners as Parts Not Available Safety and Emissions Recall 5 321 K – Multi-Model Fuel Pump May Fail Dear Mazda Dealer Partners, As advised last November, Mazda Motor Corporation has decided to conduct a Safety Recall impacting certain 2018-2019 CX-5, CX-9, and MX-5 Vehicles as well as 2018 Mazda6, and 2019 CX-3 in the US. Owner Notification: Vehicles will display in eMDCS as “Preliminary Notification” tomorrow, January 5, 2022. Updated communications will be sent once sufficient part levels become available. Sufficient parts for a full launch are not expected until May or June 2022. REMINDER: For CPO Inventory Vehicles Action Required: Please review a copy of the owner letter describing this recall and the launch timing. The Customer Letter is available for download and printing on MGSS. Have a copy of the customer letter available for the customer to acknowledge and sign. Place the signed customer letter in the deal jacket. Obtain all the customer’s current contact information including email and cell phone numbers, so that they can be reached once the parts are available. MNAO CPO certification requirements state the recall must be performed prior to the CPO sale. During these times of unprecedented supply chain issues and the on-going global pandemic, this is not possible given the repair parts to launch the recall will not be available until May or June of 2022. When an adequate number of parts arrive to the PDCs, MNAO Parts Operations will distribute push shipments to dealers. By following this interim process, the vehicle can still be delivered, and CPO certification will still be granted. For customers who insist on repairs being completed: Place the customer in a MCVP vehicle and fill out Dealer Recall Help with a copy of the RO and advise the recall team will contact the dealer back once parts are available and advise next steps. Note: All third-party rentals must be approved via Warranty pre-auth goodwill in advance. 476254 514334 403654 428073 300008 206202 303267 Subject Vehicles: Affects 121,038 US and US Territory vehicles: Model Subject VIN range Subject production date range 2018-2019MY JM3I<.F**** J* 387268 – From April 3, 2018 through CX-5 (l<.F) JM3I<.F**** K* 500024 – October 27, 2018 2019MY JM 1 DK**** I<.* From April 10, 2018 through – CX-3 (DI<.)

If these vehicles are in the US, they can be repaired at any US Mazda dealership. Please see the specific description, model, year and VIN Ranges below. Concern Outline: The impeller in some low-pressure fuel pumps may become deformed under certain conditions, which could cause fuel pump failure. Subject impellers were manufactured with inadequate material which may lead to surface cracking, resulting in impeller deformation. The impeller may deform to the point where it interferes with the fuel pump body, causing fuel pump failure. Fuel pump failure may result in engine no start and/or vehicle stall while driving at low speed and, in rare instances, a vehicle stall could occur while driving at higher speeds, increasing the risk of a crash. Additionally, drivers may notice this defect by a check engine light, and/or rough engine operation. For all subject vehicles: When parts become available, dealers will replace affected fuel pumps with improved parts. Important Safety Notice: The National Traffic and Motor Vehicle Safety Act prohibits the delivery of any subject vehicle without performing the necessary repair for defects or failures. Failure to perform applicable recalls before delivery can result in extensive dealer fines and penalties from the Federal Government. Therefore, you must complete this recall for all affected vehicles in your inventory prior to delivery. 1. Parts and Warranty Information and Repair Procedures will be posted on MGSS once finalized. 2. For Warranty questions, contact the Warranty Hotline at (877) 727-6626, Option 3. 3. Vehicles will display in eMDCS as “Preliminary Notification” on January 5, 2021. 4. For parts questions, contact the Dealer Assistance Group at (877) 727-6626 Option 2. 5. For Recall questions please fill out the Dealer Recall Help Form located on OneMazda > Warranty, Recall and Service Tools. Please make certain the appropriate personnel in your dealership are aware of these resources and are familiar with the details of this recall before responding to customer inquiries. We apologize for any inconvenience this recall may cause you and your customers. Your understanding and support in carrying out all campaigns are greatly appreciated.

Parts Ordering – for all Subject Vehicles: Beginning on Wednesday, July 13th Mazda will process push shipments for the recall repair parts.

• • • MAZDA D A ER MAIL September 9, 2022 Attention: Mazda General, Parts, and Service Managers Subject: Recall Claim Submission Reminder- Safety and Emissions Recall 5321 K-Multi-Model Fuel Pump May Fail – Claims Issue Dear Mazda Dealer Partners, This is a reminder notice, as Mazda Warranty Operations has discovered that certain Recall 5321 K claims have been submitted with the incorrect Part Number Main Cause (PNMC) or Related Parts. In these situations, a debit will be issued. It is unacceptable for a dealer warranty administrator to choose the wrong template to process multiple claims quickly. In the case where the incorrect template was used, the dealer will need to appeal each debit issued with a copy of the repair order that verifies the correct parts were installed. If the repair order does not clearly identify that the correct part(s) were installed, the Recall will have to be re-opened and the customer could be notified by Mazda that the dealership incorrectly repaired their vehicle and that they need to return for the correct repair. It is not acceptable to simply state the repair order had a clerical error; the repair will have to be redone or rechecked to ensure the correct part was installed on the vehicle. Action Required: It is imperative that all dealer service personnel ensure that all repair procedures are properly followed and executed when repairing any vehicle at their dealership, whether Warranty, Recall, Campaign, or other repair. It is equally imperative that every dealer always submits an accurate claim submission. Mazda’s goal is to always repair the vehicle to the highest standards with our collective focus on customer safety, reliability, and instilling confidence once the vehicle leaves your dealership. Parts personnel must check that all parts match the model, model year, engine, and drive type. If the incorrect part was received, contact the Dealer Assistance Group (DAG) immediately. Technicians also must make sure the replacement part is the correct part, again by model, model year, engine, and drive type, utilizing MGSS and any Recall/Campaign documentation. Warranty administrators must check parts on the repair order and apply the correct Warranty information and/or Claim Template which represents the repair performed. Do not blindly pick and choose the most convenient option for submission. Otherwise, your claim is subject to denial or debit. We appreciate everyone’s patience and support in carrying out repairs for all Mazda Recalls/Campaigns. If you have questions about this email, please fill out the Dealer Recall Help form on OneMazda ( Click here ) or contact the Mazda Warranty Department.

• • • ~ MAZDA D ALER MAIL September 14, 2022 Attention: Mazda General, Parts, and Service Managers Subject: Warranty Claim Debits Due to Incorrect Recall Part Submission – Safety and Emissions Recall 5321 K-Multi-Model Fuel Pump May Fail Dear Mazda Dealer Partners, Mazda Warranty Operations has identified a small percentage of Safety Recall claims that were submitted under Recall 53211< and paid with a fuel pump that did not match the vehicle. Unfortunately, the claim submission error forces Warranty Operations to debit all incorrectly paid claims. At the suggestion of the region management, this dealer email is being sent as advance notice of the upcoming debits, and to reinforce the message in the Dealer Email sent on September 9, 2022. Approximately 1,600 debits will be performed starting Wednesday, September 14th• Many dealers had zero errors and some dealers had 1 or 2 errors. Action Required For each debited claim pull the repair order to confirm if the error was in submission or if the incorrect part was used. Claim analysis shows most issues occurred during submission. Warranty Operations believes that either the incorrect template was selected, or the template was not changed to match the various models. Wrong Part Entered on the Warranty Claim If you have verified the correct part was installed and the repair order reflects the correct part, appeal the debited claim, and attach a copy of the repair order showing the correct part was documented and replaced on the vehicle. Each appeal will be pending for review, and this may take several days to complete. Incorrect Part Installed If you have determined that the incorrect part was installed, or you cannot reliably determine the installed part matches the vehicle, the customer will need to return, and the correct fuel pump will have to be installed. Once completed, submit the claim for the proper replacement and attach a copy of the new repair order showing the correct part was replaced Currently Appealed Claims This week, if you have submitted an appeal in an attempt to correct your original recall repair; thank you. We are in the process of reviewing all appeals and they will likely be processed this week. However, the original claim will still require the debit. • • • Once the entire process has been completed, the dealer will see a debit for the original paid submission and an appeal for the correct submission. This will net out as 1 payment for 1 repair. We will not simply accept an explanation that the repair order had a clerical error, the wrong part was charged out, but we know we installed the correct part. It is imperative that all dealer service personnel ensure that all repair procedures are properly followed and executed when repairing any vehicle at their dealership, whether Warranty, Recall, Campaign, or other repair. It is equally imperative that every dealer always submits an accurate claim submission. Inaccurate claim and/or repairs could expose your dealership to substantial fines from NHTSA. Mazda’s goal is to always repair the vehicle to the highest standards with our collective focus on customer safety, reliability, and instilling confidence once the vehicle leaves your dealership. Best Practices. for All Warranty and Recall Claims Parts personnel must check that all parts match the model, model year, engine, and drive type. If the incorrect part was received, contact the Dealer Assistance Group (DAG) immediately. Technicians also must make sure the replacement part is the correct part, again by model, model year, engine, and drive type, utilizing MGSS and any Recall/Campaign documentation. Warranty administrators must check parts on the repair order and apply the correct Warranty Information and/or Claim Template which represents the repair performed.
