Service bulletins for the 2017 Mazda MX-5

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

00-001-18-3446a2018-11-13. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; EQUIPMENT. Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle- specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers.
01-016-18-35222018-10-09. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. 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 to oxidize. As the vehicle is driven, the oxidizing reaction odor in the converter will decrease with mileage and age.
MT-008-182018-10-09. Service bulletin. ENGINE; ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY.

MT-007-182018-10-09. Service bulletin. ELECTRICAL SYSTEM. Some customers may complain about the following: Engine no start. A blurry rear view monitor display. This may be caused by an aftermarket accessory device. Some aftermarket electrical devices (e.g., an accessory cell phone charger, GPS tracker...) may create excessive electrical noise.

09-034-18-34302018-09-10. Service bulletin. VEHICLE SPEED CONTROL. In accordance with Federal regulations, follow the procedure listed below when replacing a speedometer. NOTE: Tampering with a motor vehicle odometer is strictly prohibited by Federal, and State laws. It is the dealer's 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 Mazda's 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 SPECMO's 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.

SA-034-182018-08-20. Service bulletin. EQUIPMENT. MAZDA CONNECT SYSTEM FREQUENTLY ASKED QUESTIONS (FAQ)
09-028-18-34902018-08-20. Service bulletin. STRUCTURE; SEATS. Some vehicles may exhibit scratches (1) on the rear of the seat back bar garnish (2) from contact with the convertible top (3). Due to assembly variations, the clearance between the seat back bar garnish and the convertible top is too small on some vehicles. On later 2016 models (starting with VINs JM1ND******117681), the link stopper of the convertible top has been changed to adjust the opening angle and folding position of the convertible top. This increased the gap between the seat back bar garnish and the convertible top when folded down. On these later models, the issue seems to occur if the customer does not completely lock the convertible top down when lowered. NOTE: Make the customer aware that the top needs to be completely locked down when lowered to prevent this from happening. With the convertible top lowered, press down on both the front and rear areas of the top (as shown with the arrows) until a latch sound is heard and the top does not pop up.
09-020-18-3458a2018-08-20. Service bulletin. EQUIPMENT. Some vehicles may exhibit a Connectivity Master Unit (CMU), a BLUETOOTH® hands-free unit or text messaging related concerns. To improve the handling of BLUETOOTH® hands-free and/or text messaging customer concerns, Mazda created a special service and parts exchange program as of February 2010.Customers experiencing related concerns should have their vehicle and/or device inspected according to the following procedure.
09-010-18-3440a2018-08-20. Service bulletin. ELECTRICAL SYSTEM. Some vehicles may experience the symptoms mentioned below, which can be fixed with the latest software update (Version 59.00.546 or later). NOTE: For 2016 CX-9 with version earlier than 59.00.441, the tachometer function will be removed from the Active Driving Display as part of Mazda's continuing efforts to improve safety and reduce driver distraction. Please explain this to the customer before updating the software. If the customer agrees, turn off the tachometer display on the AD-Display tab in MAZDA CONNECT Settings before performing the update. NOTE: If the customer has customized MAZDA CONNECT with something like a different background using unauthorized software, make sure they know the following information before updating MAZDACONNECT to avoid any issues later on. Updating MAZDA CONNECT to the latest version will erase any customization created by unauthorized software. Unauthorized customization software will not work on the latest version of MAZDA CONNECT software. The latest version of MAZDA CONNECT software cannot be rolled back to an earlier version. Mazda does not recommend unauthorized customization of MAZDA CONNECT due to the possibility of unexpected problems. Any issues related to this will not be covered under Mazda warranty policy.

If a vehicle is driven on extremely short trips most of the time (where the engine never reaches normal operating temperature), the engine oil may become diluted with fuel and the engine oil level will increase. Engine oil dilution with fuel occurring under this specific driving condition is normal with direct injection engines. If the vehicle is driven on a longer trip after a lot of short trips (where the engine reaches normal operating temperature), the Check Engine Light may turn ON with DTC P0172:00 (Fuel system too rich).
SA-024-182018-07-02. Service bulletin. STRUCTURE:BODY:HOOD. Some customers may complain of a lack of power under heavy load without any warning lights or DTCs. This concern may be due to a loose or detached hood weatherstrip, which can cause a blockage or restriction in the air intake system.
SA-023-182018-07-02. Service bulletin. LANE DEPARTURE: WARNING; EXTERIOR LIGHTING:HEADLIGHTS:HIGH/LOW BEAM DIMMER SWITCH. Some vehicles may have DTC C1001:92 stored in memory.
