The right front tire was completely flat on my brand new 2017 Santa Fe Limited Ultimate (purchased Labor Day, 2017). I filled it up and got it drivable. I am a Blue Link subscriber, so I contacted Blue Link about the issue, and I was rudely told by the Blue Link employee that Blue Link cannot help me with this and suggested I call a Hyundai dealership. I called Shortline Hyundai, Aurora, CO service department. Was told they could not help me since they do not carry tires in their service department and that it would be better for me to call a tire shop, recommended Discount Tire. Took to Discount, they were great, and replaced the valve stem, which they said had a "fold" in it and said it was installed incorrectly, thus a manufacturer warranty item. I paid $90 for this service. 2 Days later I contacted Hyundai support for reimbursement and spoke with "Eric," who at first told me there was nothing he could do and that I'd need to contact the tire manufacturer on my own. He did not offer to help me find this information, nor volunteered to contact them for me. I pushed back saying I was, "disappointed," at the level of service I was getting, to which he explained in a very passive aggressive manner the steps I'd need to take since the tires were not really Hyundai's problem. He clearly stated this was the tire manufacturer's problem. And he placed the burden of work for me to figure out who to call. I became very upset and responded by demanding the work be done for me, the customer, as Hyundai has "America's Best Warranty." Only after getting "ugly" with him, did Eric then ask me for the Discount tire location's phone number and only then he volunteered to call Discount to find out what kind of tires I had. Once he found out the tire brand, he did call me back as he said he would but then only suggested I contact the tire manufacturer to get satisfaction. To add insult to injury, the Tire Mfr. was closed on the weekend. So now I have to contact them during work hours as a further inconvenience. America's Best Warranty, I think not. ~Disgruntled customer.
