finally i got engine block crack on my Honda civic 2008 – with only 78k miles on it, local dealer quoted $3500 for the repair (replacing the engine)…Worked with honda over past 3 weeks, they were of no help, refused to do anything further. Given the age of the car only option for me is to scrap than spending 3500 on it,
Honda dont give any consideration of my long standing Honda loyalty (i owned 3 honda vehicles),and regular service history/oil changes etc… they just told this is outside of 10yr ext warranty…
Car was in very good running condition until this problem just popped up…Had spent almost 1200k on various recommended maintenance work in the past 1 year, hoping i could keep it for couple more years given the low mileage…no warnings, until one day coolant smell and overheating, stopped the vehicle, towed it to the dealer and just 3 weeks later I am looking for a scrap buyer… 
Anyone driving a Honda Civic out there from these defective VIN series, better get rid of your vehicle before this happens to you…while there are only a low % cars with these defects, it is not 100s but easily in many thousands… Honda conveniently will never disclose those numbers… They will not even respond to you in email or writing on these cases…
Most dealers i talked to in Houston areas have seen many cases of these, so nationwide you can guess how many could be there… I was thinking of low probability until this all happened. Don’t expect any sort of help from Honda as it is way past 10yr ext warranty…
