When replacing the SiriusXM satellite radio unit (or a MAZDA CONNECT tuner and amp unit (TAU)) with replacement tuner for any reason, a call must be made to inform SiriusXM of the existing Radio ID and the new/replacement SAT Radio ID as soon as possible to ensure the customer leaves the dealership with active working SAT radio.
08-001-19-35442019-02-19. Service bulletin. AIR BAGS. This information is provided to help address Passenger Airbag Deactivation (PAD) Indicator illumination concerns during vehicle service.
04-001-19-35562019-02-19. Service bulletin. SERVICE BRAKES, AIR. Some customers may report a slight clunk/bang/buzz noise or jolt from the front of the vehicle. 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.
02-004-19-35742019-02-19. Service bulletin. STEERING. Some customers may complain that the steering wheel is off center more than 3° even when driving straight on a flat road.
02-003-19-35472019-02-19. Service bulletin. SUSPENSION. Beginning with the CX-5, grip type front and rear stabilizer bushings have been incorporated for noise prevention purposes. If any type of grease or lubrication is applied to the bushings, it may create noise due to bushing slippage.
02-002-19-35462019-02-19. Service bulletin. WHEELS. Some automotive cleaning products contain strong acid or alkali. When these types of cleaners are used to clean the wheels on Mazda vehicles, the chemicals contents penetrate the clear coating of the wheel surface and damage the paint under the clear coating. The damaged area has the appearance of dark stains.
02-001-19-35502019-02-19. Service bulletin. SUSPENSION. Some customers may complain of signs of oil on the struts or shock absorbers. In most cases the oil that is present is normal, and a result of the oil that remains on the shaft during the normal sweeping process of the shaft seal. Follow the inspection guidelines to determine if the condition is a result of the normal sweeping process or a failure of the shaft seal.
01-006-19-35492019-02-19. Service bulletin. ELECTRICAL SYSTEM. The vehicles listed above are equipped with a push button start/stop ignition system. Unlike previous Mazda models, there is no key cylinder on the steering column. Therefore, the engine cannot be started with the auxiliary key if the room fuse is removed or if the transmitter battery is dead.
01-005-19-35482019-02-19. Service bulletin. ENGINE AND ENGINE COOLING. Some vehicles may exhibit the check engine light on with DTC P0456 stored in the PCM memory. P0456: EVAP system leak detected (very small leak). The concern is most likely the result of the customer not getting the fuel cap completely closed after fueling the vehicle. This causes a small fuel vapor leak and turns DTC P0456 on.
01-004-19-35582019-02-19. Service bulletin. ENGINE AND ENGINE COOLING. On some vehicles, a sulfur smell or 'rotten egg' odor may be noticed coming from the exhaust system. 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.
01-003-19-35572019-02-19. Service bulletin. ENGINE. Some vehicles may experience the CHECK ENGINE LIGHT ON with DTC P2610 and P2507 stored inmemory after engine start and room fuse 15A (A) removed. P2610:00: Instrument cluster internal engine off timer performance problem P2507:00: PCM battery voltage low input As a past malfunction, the customer will not notice it (no warning light illuminated), but the DTC may be found during a vehicle service. 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). Vehicles in dealer inventory with this concern should be repaired using the following repair procedure.
01-002-19-35522019-02-19. Service bulletin. ELECTRICAL SYSTEM. The Mazda GR8-1291 is required for all warranty battery testing. If the Mazda GR8-1291 is not used, incorrect battery testing may result in unnecessary battery replacement. 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.
