The Hyundai Webtech web site is the consumer version of the HyundaiDealer web site. While they seem almost the same, the Dealer one will not let you in unless you know the dealercode and password or the master password. Its not much different really except for a few more tabs and access to the Document Recourses pages. The consumer one is adequate for owners to look up any techincal service bulletin that has been issued as well as recalls notices etc.
Note: While the site itself is catered to US owners, it is a Hyundai authorized site and as such any TSB you encounter there can be printed up and taken to any Hyundai dealership elsewhere like in Canada and most likely they will check with central office and confirm the tsb. But take note, some Canadian dealership will not acknowledge any US tsb regardless, unless it shows up in their system as well.
