Answering for better accuracy since early Hyundai GDI engines DO have build-up issues in the GDI system that need to be addressed from time to time :-(. It's not something you need to do a LOT, but when you have issues it may be needed.

The problem with the GDI engines is you can't clean these out with a full tank of gas and a 30-minute Italian tune-up; the system doesn't benefit from that these days. Even worse is when it gets bad enough you sometimes need to sandblast the heads with walnut shells... Not cheap. The way to clean these is you need to find the vacuum line that goes to the engine, pull it, and then install an adapter on the line that can accept a fuel injector cleaner; once you do that you need to spray cleaner into the engine and that cleans the dirt out of the engine. Refer to [https://www.youtube.com/watch?v=ChbbR-FEX-8|this video|new_window=true] for a general location. For the most part, the location will be similar on most Hyundai/Kia engines.
