I also bought a Corolla altis 1.6 2nd hand 6 months ago and it has some chik chik noise coming from front end from past few days. When this chik chik stops dash rattles at the clock area maybe it's not properly attatched. Moreover on the front seat a noise comes from seat belt on bumpy roads. The chik chik noise is really annoying other noises are bearable because they disappear on smooth roads while this chik chik even stays on motorway at 120kmh
