The 2009 Mazda 6 falls slightly below the UK average with a 77.6% first-time pass rate versus 80%, and this is compounded by a concerning 41.5% of vehicles having recorded dangerous defects at some point—well above what you'd expect for a car of this age. Petrol and diesel variants perform almost identically (78.1% and 77.3% respectively), so fuel type won't be a deciding factor in reliability.
At nearly 94,000 miles median mileage, these cars are showing their age with an average of 3.18 failures per test and nearly 20 advisories each, suggesting that wear items and minor corrosion are becoming routine issues rather than exceptions. Before buying one, get a full pre-purchase inspection focusing on suspension, exhaust, and brake components—these are the typical culprits—and budget for near-term repairs rather than expecting a trouble-free ownership period.
The 2009 Mazda 6 has a decent first-time pass rate (77.6%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.
These stats describe 10,300 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
