Advice for buyers
What should I look for in a used Mazda 6 estate?
Entry-level SE cars come without front and rear parking sensors – a shame, because the 6 is quite a large car. As a result, it’s worth checking for parking scrapes and dings if you’re choosing one of these models.
Some of the interior plastics on early 6 Tourers aren’t as good as later ones and can show marks and scratches. If you happen to be looking at an example with the optional off-white interior, make sure the seats aren’t stained and are in good condition. Being such a light colour means it shows up even the smallest bits of dirt, so be prepared to clean it regularly.
The second is for another software issue, but with the fuel injection system on examples built from 26 January 2012 to 21 January 2016. Again, you will need to go to a Mazda dealer to have the software updated in order to prevent future issues.
Engine hydraulic valve clearance adjuster
The hydraulic valve clearance adjuster on cars made between 26 March 2018 and 22 April 2019 might not have been programmed correctly and requires an update to be performed in order for it to function as intended. Speak to a Mazda dealer for further information.
The vacuum pump that works as part of the braking system could wear out on examples made from 26 January 2012 to 21 January 2016 and could result in reduced braking assistance. If your Mazda 6 is affected by this, it will need to have a new pump fitted.
A soot build-up in the intake shutter valve in the engine could cause problems on models made from 26 January 2012 to 30 June 2018. Contact a Mazda dealer to find out if this applies to your car, because the valve will need to be cleaned out and a software update performed to prevent this from recurring.
The fuel injectors on some examples that were made between 26 January 2012 and 21 January 2016 might not have been tightened down correctly. Any Mazda dealer will be able to tell you if your car is affected by this and will check the tightness of the injectors for you if it is.
There is a small possibility of a vehicle fire due to an issue with the DC-DC converter that forms part of the engine start-stop system. It only applies to early cars manufactured between 31 July 2012 and 3 March 2013, so speak to a Mazda dealer to find out if this applies to your example, because it will need a new DC-DC unit.
