Advice for buyers
What should I look for in a used Mazda 3 hatchback?
There isn’t much to worry about. Diesel Mazda 3s have particulate filters, so make sure you steer clear of any warning lights that arouse concern as these can lead to costly repairs. In 1.6-litre versions, the particulate filter is cleaned with an additive called Eolys, and when this runs out it needs topping up, so make sure this has been done on time – usually around the 75,000-mile mark.
What are the most common problems with a used Mazda 3 hatchback?
They’re few and far between, fortunately, though 1.6-litre diesel models have been known to suffer with injector faults. Symptoms include a loss of power and warning lights on the dashboard, and replacement injectors can be costly.
Is a used Mazda 3 hatchback reliable?
Yes, on the whole, although some rivals have a better reputation. The 3 gets an above-average score in the What Car? Reliability Index, though it falls short of the lofty standards of the Honda Civic.
That’s a situation mirrored by Mazda as a whole in the JD Power Vehicle Dependability Survey – it’s above average, but only just, and some manufacturers perform better.
