Protect house buyers beyond defect liability period

I WOULD like to highlight a problem faced by house buyers with regards to developers avoiding their responsibility by hiding in the safety of an expired defect liability period (DPL).

I bought a two-storey terraced house in Bandar Setia Alam. The DPL expired in October 2014. Recently, the tiles on the ground floor broke loose and I had to hire a contractor at a cost of about RM10,000 to lay new tiles.
