What should I look for in a used Seat Altea estate?
The Altea isn't as solidly built as some Seats, with a number of faults reported.
The main reliability issue with the petrols is the plastic timing belt tensioner - with both the 1.4 and 1.6-litre models at risk. If it fails, the engine could sustain serious damage, so consider having it replaced.
Early diesels have suffered fuel pump leaks, which resulted in a recall - so, check the service history to see if this work has been carried out. Diesel engines can also suffer an oil pump problem that can seriously damage the engine.
There are numerous other niggles, including faulty cruise control systems, problems with air-con and dodgy diesel turbos. The stability control and ABS system can also malfunction. There have also been reports of issues with some DSG gearboxes.
