As long as it has had all it's appropriate services and all synthetic oils and approved filters have been used anything under a 1000 K's is acceptable,I have found that none of the warranty work either of mine have had to have done,servicing intervals have never been questioned,but in one case a smaller dealer,which was asked to do a small warranty job,DID question that I was not using Hyundai as the servicer and that I was not using original Hyundai service parts,but under their own warranty statements this also is not an issue,don't let Hyundai bully you into thinking anything else.
