NHTSA's summary
TSB:V6 FUEL INJECTOR REPLACEMENT - This bulletin provides the procedure to replace all the fuel injectors on some 2014MY Sorento (XMa) vehicles, which may experience an intermittent rough idle on cold starts. When addressing the concern of a rough idle, which occurs only on the first start of the day and lasts for thirty (30) to forty-five (45) seconds, check for the possibility of poor injector performance in any cylinder. This concern may feel like a misfire, however, it is not an emissions or catalyst damaging misfire and typically does not trigger any DTC(s). To diagnose this concern, go to GDS ? Engine ? Current Data and monitor for Current Misfire Counts on all 6 cylinders, during the first cold start in the morning.

PIT STOP: GDI INJECTOR SPRAY TIP DEPOSITS - A design feature of vehicles equipped with a Gasoline Direct Injection (GDI) system is the placement of each fuel injector directly into the engine cylinder head assembly.
