I bought mine new and I did take it to the dealer for service. It began using oil around 45,000 miles, 1 quart every 1,000 miles. They said it was within standard usage. They declined to investigate. I highly recommend taking it to the dealer until it is out of warranty. Even though they did not address my issue it would have been extremely difficult if service was provided elsewhere.
I used the dealership for the first 40K miles or so, but they’re like 6 weeks out for an oil change. I now just use a 10-minute ‘stay in your car’ shop that uses Carfax, which the dealer can see. Had a minor issue at 70K and they honored the warranty with no hassle at all.
I’m not telling you to, but on my 2017 Tucson, everything but tire stuff has been at the dealer’s service center. It just gives me massive peace of mind and that’s worth a lot to me. Plus, my local Hyundai service is awesome, so that’s a bonus.
Nope. Lawsuits were filed and the dealers lost this fight long ago. They tried to stipulate that you had to have service done at the dealer using the manufacturer’s parts to preserve your warranty. This was in the 70s.
The auto parts chains and auto shops rallied big time to fight it. It was determined that as long as you used parts made to the specifications given by the manufacturer and had work performed by quality technicians, your warranty remained intact.
It was a huge win for consumers. Prices on parts, service, and repairs would be astronomical if this power grab had been allowed.
It’s not required but if you go elsewhere you need to keep every receipt as proof when you need something warranty.
Yes and read your owner’s manual.
No. Keep records.
Here’s from experience dealing with Hyundai in Belgium:
Bought a Hyundai used car from a Hyundai dealer. It was part of their Hyundai select program. Did my maintenance and all myself. After a few years I noticed some rust starting to turn near the panoramic sunroof… It was still covered in the 12 year Hyundai corrosion warranty, but since I did not have corrosion proof stamps with the Hyundai name on it in my service book, the claim was rejected.
It depends entirely on your service agreement. If the log book is stamped some places will honour it.
Are there other things in the dealer contract that you might have to consider? For example, in my region, Hyundai provide roadside assist, 24/7 country wide. However, there is a stipulation that you have to get one service per 12 months done at a dealer to retain that service.

same city too 
Hyundais have a horrible problem of engines blowing up and the dealers doing absolutely nothing about it… You need to sell it as soon as you can.
Don’t miss a service. It voids the warranty so I found out. Hyundai won’t replace a motor even though it’s only done 187,000 Km’s. Never buying a Hyundai ever again.
