The 2003 Mazda 3's 74.1% first-time pass rate sits 5.9 points below the UK average, signalling moderate reliability concerns—but the real red flag is that a third of these cars have recorded dangerous defects during their MOT history, which is well above the typical threshold and suggests buyers should factor in potential safety-critical repairs. At nearly 74,000 miles on average, these cars show typical mileage for their age, yet they're accumulating nearly 4 failures per test and almost 20 advisories, indicating wear across multiple systems rather than isolated problem areas.

Any 2003 Mazda 3 you consider should be inspected by a trusted mechanic before purchase, with particular attention to the systems generating those recurring advisories—brake wear, suspension, and exhaust components are common culprits in this generation—and you should walk away if the seller can't produce a full MOT history showing the pattern of defects.

We have limited data for the 2003 Mazda 3 — treat the figures below as indicative rather than definitive.

⚠️ 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.

What tends to go wrong

Across 197 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 107.4%
Nearside Front Tyre worn close to the legal limit · Offside Front Tyre worn close to the legal limit · Offside Rear Tyre worn close to the legal limit · …

Front Brake pad(s) wearing thin · Rear Brake pad(s) wearing thin · Parking brake: efficiency below requirements · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Suspension & steering 32.2%
Nearside Front Suspension arm rubber bush deteriorated but not resulting in excessive movement · Offside Front Suspension arm rubber bush deteriorated but not resulting in excessive movement
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.

Child seat fitted not allowing full inspection of adult belt
Lighting 23.3%
Nearside Front position lamp(s) not working
Usually cheap to fix. Worth confirming all lights work before collecting.
