Non-linear acceleration issue 2010 4.6 Tech Package

[Vennim2014]

So I've owned my 2010 Genesis 4.6 Tech Package for 4 years now and love the car except for one gremlin that continues to haunt me with no resolution. The car starts, idles, drives virtually perfect except when under mild to moderate acceleration or steady cruising at lower speeds (30-50 mph). It's like it has a stutter and hesitates as the speed climbs. No codes...no CEL....no stalling. Just not right and it's annoying to say the least. Our local Hyundai dealers are clueless and frankly seem to care less to resolve this issue. I know I'm not the only one in this situation. I love this car but I'm seriously considering letting it go if I can't find a solution soon. Any help would be greatly appreciated!

Just wondering, did you get this resolved? I'm curious because I have some sort of stutter or chatter when under moderate load, but I only notice it in 1st or 2nd gear. And it doesn't seem to happen when I have the transmission in manual mode. Anyone else have this kind of issue? (My car is a 2010 4.6 also, but I think it has the Premium Package)
