Common Mazda MAZDA3 problems

Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.

Automatic gearbox health · €300–€2,500

Make sure the gear changes are smooth when warm, check for a gearbox warning light and ask if the gearbox oil was ever changed.

Timing belt history · €350–€700

Ask when the timing belt and water pump were last done (usually every 160,000 km or 5–6 years). No proof = budget for it.
