I did put some extra pressure on Hyundai USA. They are investigating further and contact me tomorrow. If it doesn't work I will contact the Attorney General office.Have you contacted your state's Attorney General, department of Consumer Affairs? They may be able to push Hyundai to get their records straight and honor the warranty. Contacting the local Better Business Bureau may work, or not, as they have no authority over Hyundai, but the state attorney general does.
