The SEAT Altea was built from 2004 to 2015.
For this generation we cover 6 engines and 34 known faults, each with the mileage range where it usually appears.
The most expensive known risk is Piston damage (1.4 TSI twincharger 140–185 hp): it usually appears at 60,000–160,000 km and costs €2,000–5,000 to fix.
In UK roadworthiness tests in 2024, at 150–200 thousand km this model most often failed on: lights, wipers and visibility (20.6 %), suspension (18.3 %), brakes (13.1 %). It fails more often than an average car of the same age and mileage on: body and corrosion. It fails less often than average on: steering.

The faults with the highest risk: piston damage (1.4 TSI twincharger 140–185 hp) (60,000–160,000 km, €2,000–5,000); excessive oil consumption (Gen 2, 2008–2012) (60,000–180,000 km, €2,500–5,000); big-end bearing failure (BXE / BKC / BLS) (150,000–280,000 km, €1,500–3,500); cracked cylinder head (16v BKD / AZV) (120,000–250,000 km, €1,200–2,500). The full list by engine is on this page.
In UK roadworthiness tests in 2024, at 150–200 thousand km this model most often failed on: lights, wipers and visibility (20.6 %), suspension (18.3 %), brakes (13.1 %). It fails more often than an average car of the same age and mileage on: body and corrosion. It fails less often than average on: steering.
Before you buy, ask an authorised dealer to check by VIN that the recalls have been done (8 have been published for this model). If the engine has a timing belt, ask for the invoice for its replacement: with no proof, assume it has not been done. On the test drive, watch for these signs: misfire, low compression on one cylinder, oil use; needs 0.5–1 L per 1,000 km, blue smoke, sooty plugs. The full checklist is in the guide to buying a used car.
These models share engines with this car, so they share some of its faults too.
