Advice for buyers
What should I look for in a used Mazda 3 hatchback?
Rear parking sensors weren't standard across the range, so your prospective purchase might not have them fitted. Due to the rather thick rear pillars, you might find it quite hard to park – at least initially. The previous owner might also have struggled, so check the extremes of the car for damage, because this could be costly to put right.
What are the most common problems with a used Mazda 3 hatchback?
Hydraulic valve clearance
The software controlling the hydraulic valve adjuster on certain models built between 7 November 2018 and 13 May 2019 will need to be updated by a Mazda dealer to make sure it all works correctly.
Loose wheel nuts
A problem during the manufacture of some Mazda 3s made between 7 November 2018 and 13 May 2019 could mean that the wheel nuts aren't tightened correctly. If your car is affected, a Mazda dealer should check the tightness of the wheel nuts for you.
Is a used Mazda 3 hatchback reliable?

In the family car class, it was down in 22nd place out of 31. Mazda as a brand is only in a middling position of 17th out of 31 car manufacturers, behind Volkswagen, Seat and Ford.
