The 2014 Mazda 6 is slightly more reliable than average, with an 83.8% first-time MOT pass rate versus the UK average of 80%, but the dangerous defect rate of 36.4% is a genuine concern—well above the typical threshold—so have any potential purchase inspected thoroughly before committing. Petrol versions edge ahead at 85.1% pass rate compared to diesels at 83.4%, though both are respectable.

At 76,411 miles median, these cars are running typical mileage for their age, and the average of 1.75 failures per vehicle suggests wear is catching up with age. With 12.8 advisories per vehicle on record, expect accumulating minor issues like worn brake pads and suspension components, so budget for gradual maintenance rather than major shocks. Before buying, request the full MOT history and get a pre-purchase inspection focused on the braking and suspension systems, which appear to be where problems cluster.

The 2014 Mazda 6 has a decent first-time pass rate (83.8%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 12.8 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 7,681 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.

Watch for defects — worth knowing

What tends to go wrong

Across 7,681 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 46.5%
Nearside Front Tyre worn close to legal limit/worn on edge · Offside Front Tyre worn close to legal limit/worn on edge · Nearside Rear Tyre worn close to legal limit/worn on edge · …
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Brake wear 38.7%
Front Brake pad(s) wearing thin · Rear Brake pad(s) wearing thin · Rear Brake disc worn, pitted or scored, but not seriously weakened · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Other issues 19.5%
Nearside Rear Child Seat fitted not allowing full inspection of adult belt · Rear Sub-frame corroded but not seriously weakened
Suspension & steering 14.5%
Nearside Front Suspension arm pin or bush worn but not resulting in excessive movement · Offside Front Suspension arm pin or bush worn but not resulting in excessive movement
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2017–2025.
