Global BGP and Google

Has anyone had any experience with a Global  ASN, and Google inappropriately associating IP's to the wrong countries?   We have our AS registered in Argentina, with ARIN space under it.  From time to time, Google thinks the IP's are in Argentina, even though they are in the US.  We have this issue elsewhere across the globe as well.   I was pondering multiple ASN's, but I was not sure if there was a better method for dealing with this.     Thanks in advance!
