Rubber smell

What is your question?

have 2017 Kia forte. It has 12,000 miles on and starting a few months ago I smell rubber burning from under the hood. I do not see any leaks or any sign of belts or wires burning. Also no smoke. Not losing any fluid. Antifreeze and oil stays full. I can smell it but can't find it. I had it to dealer and they found nothing. Anybody have any ideas? or has anyone else experienced this? Thanks!
