To fellow Persona owners here, hope can get some feedback from you all that, will you car's fan/aircond/timing belt making sound like 'dak dak'? My 3 months' old Persona having the sound like this, but send to SC, said there is belt's sound, not IAFM failure's sound.... kindly give some feedback.... The dak dak sound is not hear when sit in the car, or stand beside car with bonnet closed... it just happen to hear when open bonnet.... if IAFM failure's dak dak sound, will it hear even with bonnet cover closed or sitting inside the car ?
