I'm up to 22,000 miles on my SX now and a week ago after starting up the engine, the engine light came on. After I began to drive it I noticed one thing was missing. The turbo seemed to not be working, resulting in a very un-peppy Sportage. Contacted the dealer service department right away Monday morning and they said bring it in. What was found out was the waste valve was not working properly and needed to be adjusted back to factor settings. So after that now my SX is back working as good as new..I just hope every 20,000+ this does not happens again. Has anyone else has this probably with their SX Turbo?
Other then that I have not had any major issues with my Sportage. High praise to my dealer service department for their quick service.
Wow, at first I thought you really meant the turbo went out. That would be a pretty crappy thing to have go out so soon! Waste gate adjustment is nothing though, I don't think that will be a regular recurring problem.
There is a TSB related to this for the Optima turbos. It's an electronic calculation in the pcm and the actuation rod is adjusted to bring the values back into spec. This isn't something that will need to be checked on a regular basis. You should be good to go now.

The issues I've seen here do tend to mention the wastegate. That said, I'm told twin-scroll turbocharging is new-ish to cars, and they add complexity. Also, turbochargers operate at exceptionally high RPM, while operators often don't realize the repercussions (heat, compressor stall, etc).

Twin scroll turbos are not new and are not complex. Being a twin scroll has nothing to do with boost control. The wastegate plays a part in boost control and can be actuated either mechanically, electronically or a combination of the two.
I've been dealing with a similar issue since Friday. I had no turbo but no check engine light. Kia techs didn't find anything and the turbo works now. Kinda scary because my sportage is a dog with no turbo. I have a 2012 SX with a little over 13k.
