SummaryThis bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted below in Red. 01-007/24 06/20/24 ENGINE OIL LEVEL WARNING LIGHT ON WITH DTC P250F:00 DUE TO LOW ENGINE OIL LEVEL (UPDATED WITH SSPD5 INFORMATION). All Mazda Dealers: Follow the Special Service Program SSPD5 – Valve Stem Seal Class Action for determination if valve stem seals should be replaced. 1. Verify the customer concern following the Special Service Program SSPD5 Repair Procedure. As the repair procedure states in SSPD5, confirm the engine oil is not leaking from the engine. If the customer reports engine oil is low upon arrival at a dealer, replace the valve stem seals following the flow chart for SSPD5. If engine oil is low upon arrival with no customer complaint, check for SSPD5 and if the valve stem seals have not been replaced under prior Warranty, replace the seals. If the valve stem seals have been replaced under a prior Warranty claim, contact Hotline for further instructions. If valve stem seals need to be replaced, replace the valve seals of the exhaust side with improved ones using the special tools called out in the repair procedures below. 2. Top off the engine oil (if needed). NOTE: Engine oil should not be topped off without replacement of the valve stem seals. 3. Verify the repair. NOTE: If unsure what steps to take during a customer visit for oil consumption related to SSPD5, fill out Dealer Recall Help on OneMazda.

SummaryThe coolant control valve updated part is now available and supersedes PYFD-15-16ZA. As a result, PYFD-15-16ZA is no longer available. PW5S-15-16Z is supplied with a dummy plug pre-installed. Critical Installation Requirement: When replacing PW5S-15-16Z, the Powertrain Control Module (PCM) must also be updated to the latest software version. Failure to perform the PCM update may result in drivability concerns or diagnostic trouble codes.

SummarySSPD8 - Check Engine Light ON with DTC P0126:00 - WARRANTY EXTENSION For certain 2018-2025MY CX-5, 2019-2023MY Mazda3, 2019-2022MY CX-3, 2018-2021MY Mazda6, 2020-2023MY CX-30 that are equipped with the suspected coolant control valve, the warranty coverage for specific repair of the fail-safe thermostat is extended to: 15 years (180 months) or 150,000 miles (240,000 km) whichever comes first, from the original warranty start date. CONDITION OF CONCERN: On certain subject vehicles, the check engine light is illuminated with DTC P0126:00 (Thermostat stuck open) stored in memory and one or more of the following symptoms may occur: - Engine takes longer to warm up. - Engine temperature gauge fluctuates. - Low coolant temperature indicator (blue) light stays on longer or turns on while driving. - Poor heater performance, especially at idle. Mazda Motor Corporation has made a significant repair change to TSB 01-003/25 which also impacts Warranty Extension Special Service Program (SSPD8). Repair Procedure Update: Effective December 8th all repairs applicable to TSB 01-003/25 or SSPD8 must follow the new repair procedure. The repair now replaces the thermostat with a dummy plug for the coolant control valve (CCV) along with a required software update for the PCM. Prior Repairs: Any repairs previously completed with the replacement of the thermostat or coolant control valve assembly does not require a re-repair unless there is a verified failure following the diagnosis in the TSB. It is expected that there will be no further repairs made for this concern once the plug and software update has been completed. Therefore, a return visit for symptoms related to the TSB or SSP must contact the Technical Hotline for assistance. VITALLY IMPORTANT!: There must be a “Software Update” record for the PCM when using MDARS or IDS. • MDARS - If there is no Software Update entry in MDARS or the Collect Diagnostic Information (ODR Update) is not completed (or both), the vehicle will not be considered repaired and the warranty claim will be rejected. • IDS – Vehicles programed with IDS must Collect Diagnostic Data, and that data must be attached to the warranty claim. If the data is not attached to the claim, the vehicle will not be considered repaired and the warranty claim will be rejected, denied or debited. Failure to complete the above will require the vehicle to return to the dealership and be re-repaired at the dealer’s expense with great inconvenience to the Mazda customer. Failure to perform the software update could also potentially damage the engine which would not be covered by warranty and would expose your dealership to the cost of repairs.

For all Mazda dealers, an FAQ document for this Class Action Settlement and all documents for SSPD5 will be available on Mazda Global Service Support (MGSS) on or before May 13, 2024 concurrent with notification to the Settlement Class.

The overall Mazda Powertrain Limited Warranty Extension (i.e., for all other powertrain warranty repairs) does not apply to this coverage period. • Reimbursement for paid repairs prior to August 2025: Reimbursement will also be provided for any Class Member who was denied Powertrain Limited Warranty coverage and paid out-of-pocket for a qualifying Powertrain Limited Warranty repair during the applicable period of the SSPD5 campaign.

SummarySome vehicles may exhibit a check engine light ON with DTC P20F8:00 stored. P20F8:00 - Swirl control circuit range/performance problem. • The DTC is caused by overheating of the Swirl Control Valve (SCV) motor which leads to duty limitation, causing poor openingangle response and resulting in stuck judgment. To eliminate this concern, the PCM control software has been modified.

SummarySome customers may report hearing an unusual noise coming from the power liftgate (PLG) when it is unlatching to open or latching closed. This is caused by an internal fault in the liftgate latch and/or loose bolts holding the latch to the liftgate.

SummaryThere are currently 2 methods for cutting a new auxiliary key blank. A. Auxiliary Key Trace Cut Method • B. Auxiliary Key Code Cut Method 2019 and newer models require a 10-digit key code to accurately cut keys • 5-digit codes CANNOT be provided for 2019 and newer vehicles (the traditional 5-digit code from the key tag or driver's door lock cylinder is not sufficient and will not be issued for key cutting on these models). • Only Mazda-approved key cutting machines can process these 10-digit codes. • Many older key machines do not support 10-digit codes and cannot be updated to do so. In these cases, dealers will need to purchase one of the newer Mazda-approved key cutting machines capable of handling this requirement. • For a list of current Mazda-approved machines and purchasing options, refer to the Mazda Dealer Equipment Program or view the current Mazda approved key machines below.

SummaryOn some vehicles, the front door glass run channel may interfere with the rear door garnish. Since the front door glass run channel is not fixed strongly enough to the door, repetition of door operation may result in interference and damage to the rear door rubber seal. 1. When the front door glass is closed, the glass run-channel may be forced to move to the B-pillar side. 2. Under extremely hot climate conditions, the glass run-channel may expand to the B-pillar side. To eliminate this concern, the fixing force and durability of the glass run channel against thermal expansion and vibration has been improved. The shapes of the front and rear glass run channels and the rear garnish lip have been changed to prevent interference.

SummaryThere are wrinkles on the leather seat cushion and/or seat back surface at PDI, when new vehicle is delivered, or when new upholstery is installed under Warranty repair. NOTE: This repair is not a permanent fix, it is meant to make new seats look their best when the vehicle is first presented to the customer. Wrinkles may not be completely removed after the repair is completed. Leather is a natural material and may develop some wrinkles due to aging and wear during normal usage.

SummarySome customers may complain that the tire sidewalls are distorted or "damaged". Sidewall waviness/indentations/undulations are common on radial tires and are more noticeable on tires with taller sidewalls. The higher the tire pressure, the more noticeable the effect will be. Be sure to set the tire pressures at the recommended tire pressure on the vehicle tire label. Sidewall indentations are a cosmetic condition that does not affect the performance of the tires.
