not sure why (i guess i know) but every japanese brand car i bought that was either assembled in USA or Canada had to be sent back for warranty repairs...
the worst was a 06 CivicEX i bought new as my dd which had to go in for a full week of warranty repair within 1K miles...and they gave me a rental Cobalt to ensure me that my Civic was a good purchase.
man the cobalt sucked. good psychology they used.
