Firstly, try Hyundai customer support and attempt to resolve why your dealer refuses to continue repairs. Elevate your complaint with whatever documentation you have like a bill for repairs that the dealer failed to fix. Don't be shy to complain to the regional or corporate level. In the meantime you can go online and review Alldata.diy and Mitchell Data. Both provide online service manuals second to none for a reasonable fee - once, weekly, monthly, whatever. Alldata and Mitchell provides the same service manuals (in different formats) as factory service manuals, including service bulletins all dealers have access to.
