[quote=mdesai_1981;1117871]hi,
i've got e NHC zx too in december 2008 and it is also aug'08 manufacture. but it is a normal thing as even my old car NHC (2004 model) had the same issue and nothing happened to it.

Sir
The question is not of whether something has happened to it or can happen to it or not? That in any case we cannot decide just by seeing the part until it will be tested in LAB to access the damage caused by corosion.

The question is that OEM should not have sold the vehicle in such a state or should have rectified or cleaned the part in the PDI itself so that it should not have passed on to the consumer at the price of the new.

If the OEM know that the parts ar susceptible to rust , he should galvanised the parts or use some other technology altogether before delivering to the customers.As far as cast iron parts are concerned let us assume for one moment that OK they can catch rust. But what for NUT / BOLTS & Suspension arm.

You will not notice such things in Accord/Civic or new HONDA CITY which are also from same OEM. It is only appearing in the phased out model CITY ZX.

Can anybody from some technical side like an automobile engineer can comment on this that is it tolerable to have such things in the new vehicle!

It's actually good that you have a layer of rust on your cast iron parts. That layer will prevent it from further reacting with moisture and protect the rest of it. All cast iron equipment which does not get used too often get that coating.

If you had something like stainless (or even galvanized) steel and there was even a tiny gap on the surface, it would eat through the rest of the metal in no time in the presence of moisture, unless you have some cathodic protection on it. (forms an electrochemical cell, mostly boring stuff afterwards).
