Which Mazda6 is yours?
The first generation (model code GG) was built from 2002 to 2008, the second (GH) from 2007 to 2012, and the third (GJ, then GL) from 2012 until production ended in December 2024. Sedans and wagons came with petrol or diesel engines, and the turbocharged MPS sat at the top of the range for a while.
The build plate or the service book tells you which, and that decides the battery, the brake parts and the schedule.
Battery first, or charging first?
Ask for a test before you pay for a battery. In 2014 Mazda recalled about 9,000 Mazda6 sedans and wagons built between 29 November 2012 and 7 April 2014, because water in the engine bay could stop the battery charging. A warning light and a Charging System Malfunction message came first, and the car could eventually stall.
Mazda said wet weather or deep puddles could make the generator belt slip, and the fix was a software update. If yours falls in that window, have that checked before anyone blames the battery. A red warning on the road means pull over somewhere safe and switch off.
Stop-start asks more of a battery too. CarsGuide says on a 2014 Mazda 6 it's part of the engine management and on by default, so that car's battery restarts the engine again and again in traffic. How long batteries last covers the rest.
What a good Mazda6 battery job includes
- A load test of the old battery, and the alternator's output checked
- A new battery matching the size, terminal layout and type in the manual
- A stop-start rated battery if the engine cuts out at the lights
- An invoice naming the battery, so you know its age later
When are Mazda 6 brake pads due?
There's no set kilometre figure, because pads wear with how the car's driven. A wagon doing the school run in stop-start traffic goes through them sooner than a sedan on country roads.
A light squeal at low speed is often the first hint. Grinding, a long pedal or a shake under braking means have it looked at now, and brake work is never a home job. The mechanic should measure the pads and the rotors, and the estimate should say whether the rotors stay or go. How long brake pads last has more.
Recalls to check on a Mazda6
- 2018 to 2019 cars: 1,693 recalled in July 2019 for engine computer software that could stall the engine
- GH series sold between 15 November 2006 and 30 April 2013: part of a Takata airbag recall round in August 2017
- Sold from September 2007 to March 2012: 16,535 recalled in February 2017 for a driver's seat height part that could crack or come loose
Servicing, and older diesels
Mazda's petrol models moved from 10,000 km to 15,000 km servicing for launches from 2023, and CarExpert reported in June 2026 that every combustion Mazda here now shares 12 months or 15,000 km. An older Mazda6 may show a shorter figure in its book, so the book wins.
If yours is a 2.2 turbo-diesel from around 2010, CarsGuide calls one failure a known problem: hard carbon from the top of the engine reaches the sump and blocks the oil pick-up. Ask the mechanic to look at the old oil at every service.

What we'd do with a Mazda6
Test before you replace. Get the battery and alternator checked, look up the VIN (the car's ID number, on the rego papers) on vehiclerecalls.gov.au, and fit a stop-start battery if the car has stop-start. Have the pads and rotors measured at the same visit, so you only make one trip.
