Service bulletins for the 2019 Mazda Mazda3

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.

09-034-18-3430a2018-11-13. Service bulletin. EQUIPMENT; 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.
