I have an urgent question... my dad owns a 2006 Sonata GLS V6 Premium (Canadian model) and it is in the shop now with 96,000kms. The dealer informed him that the "timing belt" needs to be replaced at 100,000kms so he should do it now (for $900). I was certain, as confirmed in these forums, that the new generation Sonatas in fact have "timing chains". But my question is, do these timing chains need to be replaced as well? I thought the point of the chain was longevity and lack of maintenance. I cannot find a straight answer online anywhere.
Do the timin belts require replacement and at what interval? Please respond ASAP. Thanks!!
