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 dealers 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.

There are currently 2 methods for cutting a new auxiliary key blank.

Read full bulletin

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.

The engine will not start using the ignition switch. 4. The transmitter operates by itself. 5. The key battery drains faster than usual. Symptoms 1-3: This may be caused when excess load is applied to the remote transmitter, deforming the electrical terminals and creating poor contact with the battery. To eliminate this concern, the structure in the remote transmitter has been modified to reduce the deformation of the electrical terminals. Symptom 4-5: This may be caused when excessive load is applied to the remote transmitter, creating a gap around the gasket where moisture enters and corrodes the circuit board which in turn drains the key battery faster than usual. To eliminate this concern, the thickness of the case wall on the gasket mounting surface has been increased and the bonding strength of the components has been improved to prevent deformation. Customers having this concern should have their vehicle repaired using the following repair procedure.

The same can happen in the hotter weather with the seat ventilation. This information is incorrect for these vehicles. Both features will now require a manual setting every time the vehicles are restarted after being turned off. Consult the vehicles owners manual for more details on proper seat warmer/seat ventilation operation.

In accordance with Federal regulations, follow the procedure listed below when replacing a speedometer.

Read full bulletin

NOTE: Tampering with a motor vehicle odometer is strictly prohibited by Federal, and State laws. It is the dealers responsibility to comply with Federal, State, and local laws concerning odometer and related documentation requirements when providing a repair or replacement. Mazda vehicles are manufactured with tamper-proof speedometers. When a speedometer is replaced, the new speedometer will read zero (0) miles. This procedure is extremely important to accurately represent actual vehicle mileage. Prior to speedometer removal, complete the information required on the Speedometer Replacement Label. Labels can only be ordered through Mazda eStore. In an effort to achieve a higher level of Customer Experience and retain the value of Mazdas vehicles, MNAO Warranty Operations is allowing all Mazda dealers to utilize a third party, SPECMO Enterprises, Inc., for Instrument Panel Cluster (IPC) odometer setting service. With the use of SPECMOs services, it is possible that the odometer will be set between 10 to 31 miles over the odometer mileage at the time of replacement for both warranty and customer pay repairs. Please make sure that the customer is aware that there may be a slight variance to the odometer, in which case the customer may have to accept the slightly higher mileage. Since odometer setting service is not part of the warranty repair, it is not warrantable nor required, but optional. However, Mazda Warranty policy provides after- warranty assistance (AWA) or DSA that can be utilized to cover this service expense.

Mazda Motor Corporation has decided to conduct a Mazda Service Program (MSP) on certain 2019 Mazda3 5HB vehicles...

Read full bulletin

produced from November 6, 2018 through May 28, 2019. Concern Outline: On certain subject Mazda3 5HB vehicles with the advanced keyless function, all doors, fuel filler door, and the liftgate can be locked by pressing the door-lock switch on the liftgate. If the liftgate door-lock switch is pressed with the transmitter/key left inside the vehicle, all doors will lock and cannot be unlocked from the outside. The liftgate can be unlocked using the liftgate opener because of the lock-in prevention function. This was the original design of the vehicle with advanced keyless function, but the original design does not match customers expectation. It is difficult to retrieve the keys inside the vehicle through the liftgate especially if the rear seats are blocked (with two child seats, luggage etc.). Action Required: Reprogram the body control module (BCM) and low-frequency control unit (LFU) with M-MDS using Mazda Diagnostic and Repair Software (MDARS) for all affected Mazda3 5HB vehicles in dealer inventory, and when customers bring their vehicles for maintenance, or other service/warranty work. The subject vehicles should not be delivered to customers until the repair of MSP56 is completed. Please inform the customer that the BCM and LFU will be reprogrammed to the modified calibration, free of charge. The modified calibration prevents the vehicle from being locked if the keys are still inside. The dealer inventory list will be posted to MGSS by the end of today. Inventory vehicles sold with MSP56 in open status will have any PDI New Car Ready claim debited.

This concern will most likely occur during the vehicles first forward movement after starting the engine. This is a normal operating noise of the Anti-Lock Brake System (ABS). Do not attempt any repairs. If you encounter a customer complaint for this concern, explain that the noise comes from the ABS/TCS/DSC "Malfunction Detection Function" initial check and that there is no problem. This initial checkis a necessary function to ensure the normal operation of the ABS/TCS/DSC system. It occurs when the vehicles first moves forward under the following conditions. NOTE: Some customers may describe that the noise does not occur all the time. It does occur all the time, but the sound is more likely to be heard on a slow start and not on a quick start (quick acceleration) when engine noise is louder.

On some vehicles, a sulfur smell or 'rotten egg' odor may be noticed coming from the exhaust system.

Read full bulletin

The odor is usually noticed after a cold start, fast idle, extended periods of idling and full throttle acceleration. Sulfur smell is not an indication of an engine concern and will not cause reduced driveability or durability of the engine or any of its emission components. The sulfur smell or 'rotten egg' odor is caused by high amounts of sulfur in the gasoline being used in the vehicle. Sulfur is normally eliminated during the refining process, but the EPA regulation of sulfur in gasoline differs from state to state. Vehicles using fuel containing high amounts of sulfur will most likely emit sulfur smell from the exhaust system.When high sulfur fuel is burned, there is a chemical reaction in the catalytic converter causing the sulfur tooxidize. As the vehicle is driven, the oxidizing reaction odor in the converter will decrease with mileage and age.

P2507 in this situation is only applicable on 2016 and later models. This is caused by the engine being started 3 or more times after a short duration of engine off (less than 15 seconds) with the room fused removed. NOTE: The odometer will display "F0-002" during transport mode (room fuse 15A removed). Transport mode is canceled when room fuse 15A is installed or the vehicle odometer is more than 12.4mi (20km).

Read full bulletin

Symptom 1 [Mazda3 and CX-30]: The active air shutter is working, but DTC P05A0:00 is stored in memory. Cause 1: This is caused by improper control software of the PCM detecting the DTC immediately without performing the failsafe operation. When the active air shutter detects unusual torque, it is designed to repeat the open/close cycles up to three times as a failsafe to try to remove the object(s) which temporarily disturbed the movement. Symptom 2 [Mazda3, CX-30 and MX-30]: The active air shutter is frozen by snow and/or ice under freezing temperatures with DTC P05A0:00 stored in memory. Cause 2 [Mazda3 and CX-30]: When a temporary blocking of the active air shutter is expected to be caused by snow and/or ice and the intake air temperature is above the freezing point, DTC P05A0:00 may be unintentionally detected. [MX-30]: When a temporary blocking of the active air shutter is expected to be caused by snow and/or ice and the heater is turned on, DTC P05A0:00 may be unintentionally detected

10228662

Some customers may complain the A/C blows warm.

Read full bulletin

This may be caused by one of two things. Cause 1: After accelerating in hot weather, the A/C blows warm air for a longer time than other models. This is caused by improper control software of the PCM not allowing the A/C compressor to resume properly after acceleration. During a hard acceleration above a certain throttle level opening, the PCM stops the A/C compressor operation for better acceleration. It then resumes the compressor operation after the acceleration. To eliminate this concern, the control software of the PCM has been modified. Cause 2: Insufficient cooling performance at ambient temperature of around 68 F (20 C) in daytime. This is caused when both the ambient temperature and the cabin temperature are at around 20 C (68 F), auto A/C set at around 20 C (68 F) may not cool down the cabin temperature properly. To eliminate this concern, control software of the dash-electrical supply unit (Dash-ESU) has been modified.

Some customers may experience a no start because the battery is discharged after the vehicle is parked for more than 8 hours.

Read full bulletin

This may be caused by one or more of the following, resulting in excessive parasitic draw (dark current) on the battery. 1. The vehicle control system may not have gone to sleep because a key fob was left in the vehicle after the ignition switch was turned off and the doors were closed. This is caused by improper BCM control logic which allows a higher parasitic draw (approx. 6A) to continue for approximately 6 minutes until the vehicle control system goes into sleep mode. If the doors are operated frequently for car washing or luggage loading/unloading etc., it prevents the vehicle control system from sleeping during that time. 2. The parking lights may have been left on because the warning sound for lights on is a short ding, and it may not be noticed. 3. [With Full-Auto A/C] The climate control unit may not have gone to sleep because the hazard warning switch was pressed after the ignition was turned off. This is caused by improper control logic of the climate control unit. To correct these concerns: 1. The control software of the body control module (BCM) has been modified to shorten the time until going into the sleep mode to approximately 2 minutes. 2. The control software of the body control module (BCM) has been modified to change the lights on warning sound to a continuous one. 3. The control software of the climate control unit has been modified.

Some customers may experience a no start because the battery is discharged after the vehicle is parked for more than 8 hours.

This may be caused by one or more of the following, resulting in excessive parasitic draw (dark current) on the battery. 1. The vehicle control system may not have gone to sleep because a key fob was left in the vehicle after the ignition switch was turned off and the doors were closed. This is caused by improper BCM control logic which allows a higher parasitic draw (approx. 6A) to continue for approximately 6 minutes until the vehicle control system goes into sleep mode. If the doors are operated frequently for car washing or luggage loading/unloading etc., it prevents the vehicle control system from sleeping during that time. 2. The parking lights may have been left on because the warning sound for lights on is a short ding, and it may not be noticed. 3. [With Full-Auto A/C] The heater control unit may not have gone to sleep because the hazard warning switch was pressed after the ignition was turned off.

Use the following test procedures in this Service Bulletin to test Mazda vehicle batteries and to generate a Warranty Code. NOTE: A Warranty Code is required for warranty claim submission Battery Identification (Mazda batteries have 2 rating types) 1. JIS (Japanese Industrial Standard): JIS codes are six-digit alpha-numeric markings molded into the top of the battery to identify a battery by the capacity (amps), dimensions, and battery terminal type. Vehicles manufactured in Japan come from the factory with a JIS rated battery. NOTE: Replacement batteries may use a CCA rating. If so, use the CCA rating listed on the battery. 2. CCA (Cold Cranking Amps):CCA ratings are normally located on a sticker affixed to the top of the battery to indicate a battery's Cold Cranking Amps. CCA rated batteries are supplied with domestically produced vehicles. NOTE: If an incorrect CCA rating is entered into the Mazda GR8-1291, it will result in a false result and invalid Warranty Code from the tester. This will also result in unnecessary replacement of batteries.

DESCRIPTION This information will give you the necessary knowledge to respond to customers concerns of Smart Brake Support (SBS) unintended braking. By educating the customer on the system operation, it should reduce their anxiety or distrust of the vehicle. IMPORTANT: Humans recognize an object with their eyes and decide whether or not to apply the brakes using their brain. The vehicle recognizes objects using the Forward Sensing Camera (FSC) and Front Radar sensor (FR), to determine brake application. Therefore, drivers may feel that the operation does not match the human feeling.

When inspected, the differential or PTO oil is dark or black.

Read full bulletin

This is considered normal and NO repair should be performed. During production, differential ring and pinion gears receive a manganese phosphate coating (commonly referred to as black oxide). This coating forms a porous, oil-retentive surface that improves boundary lubrication and reduces adhesive wear during initial contact cycles. Designed as a sacrificial layer, it is gradually removed under load throughout the break-in process. As a result, after the first few hundred miles, or at the initial gear oil service interval, the lubricant may appear darkened by the worn-off coating. It will contain trace ferrous particles from the normal run-in of the gear teeth and bearing surfaces. This condition is expected and does not, by itself, indicate an issue with the differential or PTO gears.

essential to first classify the issue into one of three primary categories: Noise, Vibration, or Harshness. Many customer complaints may involve overlapping symptoms, such as both noise and vibration, so identifying the dominant characteristic is critical. Once the primary symptom is determined, follow the appropriate diagnostic path. For example, if a concern includes both noise and vibration but is related to vehicle speed, the vibration diagnostic path should be followed. When considering component replacement during the diagnostic process, it is best practice to start with the lowest cost or most accessible part unless diagnostic evidence clearly identifies a more expensive or complex component as the root cause. This approach helps minimize repair costs and avoids unnecessary part replacements. For example, a growling or bearing whine noise may be mistakenly attributed to internal components in the differential, transfer unit, or transmission, when the actual source is a wheel bearing. Misdiagnosis like this can lead to unnecessary repairs, added time and cost. To help prevent this, always follow the guidelines in the repair procedure.

However, the situation surrounding the IVDOM has changed since then: The instrument cluster and center display provide the driver with sufficient information when an operational question arises or when a vehicle malfunction occurs. OM digitalization has been accelerating and consumer products and acceptance is rapidly growing with the spread of mobile internet devices. It has become increasingly difficult for the IVDOM to meet Cyber Security (CS) / Software Update (SU) regulation requirements. Due to these factors, Mazda has decided to discontinue the IVDOM and will shift their primary focus to the online Interactive Digital OM.

When opening the fuel-filler lid to refuel, some customers may notice water and/or sand in the fuel-filler lid box area.

Read full bulletin

They may complain about dried sand causing poor appearance. Since the drain hole on the dust cover is located in an improper position, water may not be able to completely drain which results in the accumulation of water and sand. To eliminate this concern, the dust cover (below) has been modified to drain the water more easily.

Some customers may notice a rattle noise from the instrument panel while driving that is localized at the active driving display.

Read full bulletin

The noise is generated by a deformed active driving display interfering with the instrument panel. Excessive heat from direct sunlight warps the cover lens, but does not affect the functionality of the active driving display or cause serious damage (such as smoke emission). To correct this concern, the active driving display has been modified.

Some customers may complain of condensation/fog inside the front (headlamp/headlight) or rear (taillamp/taillight) combination lights.

Read full bulletin

The recent new models have been fitted with a clear lens which can cause the symptom to be more noticeable, however, it does not affect the performance of the light. This condensation/fog is a natural phenomenon that occurs when there is a fairly large temperature difference between the inside and the outside of the light housing. It is normal for very small water drops to appear in certain locations on the light units where the air is stagnant (condensation), making the lens look whitish (fog). This happens mostly in the corners and narrow spaces, and will typically clear during warmer ambient temperatures, or when the lights have been on for some time.
