Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 75,000 mi; coolant at 60,000 mi. The big-interval services (at 60,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Within the provided timeline, complaint volumes stabilized significantly after a 2010 peak of 686, with the 2015 model year recording 129 complaints, situated between the 138 from 2014 and 102 from 2016. While the recall count holds steady at 4, matching 2014, Technical Service Bulletins drop to 742 from the 880 issued the prior year, indicating a reduction in documented technical fixes. Specific feedback highlights Service Brakes and the Electrical System as top concern areas with 22 and 13 complaints respectively, though the data does not specify the root cause of these failures. Furthermore, the 2015 record shows zero open investigations and minimal safety incidents with 8 crash and 2 fire complaints, matching the clean investigation status of 2014 unlike the active investigations present from 2007 through 2013. Given the downward trend in TSBs and stable complaint numbers relative to its peers, the 2015 Mazda MAZDA3 is a solid candidate for buyers seeking a used vehicle in this lineup.
