I was looking around on the Kia forte forum and found a thread about fixing the dead spot in the gas pedal. It's the same dead spot we have and it's the same drive by wire system so I think it should work. I looked at the pedal setup under my dash and it looks identical.
The fix is, you loosen the 5 bolts on the side cover of the pedal assembly and shift it toward the front of the car little by little till your dead spot is gone. If you go to far it will make your rpms climb. Has anyone tried this yet?

Im new to sonatas so you will have to forgive me. What does "nf" mean?

Also it might only be in the 2.4 i4s I don't know. But the Kia forte 2.0 and 2.4 both have it, and the 3 hyundais I test drove had the dead spot. I test drove my new car(2010 gls 2.4 5speed manual), a 2010 accent and a 2010 elantra. Check your gas pedal by hand with it idling and see if you can push it down any before the engine responds, that's the dead spot. My dead spot is about a half an inch and really sucks in a manual.

May I ask you to break in your Hyundai for lets say 1200 miles and get back to us on this? I know you just bought the Car,

and you are our first dead spot

NF stands for the Model we have. Some had dubbed it Neverending Faith. Its on Google. I think it stands for nothing.

Well, I just checked out my vehicle and at most the bottom of my accelerator moved 0.5" before the engine responded. I've never considered my Sonata having a dead spot and think this might be designed this way so that light resting of my foot on the accelerator, like when coasting downhill for instance, does not cause unintended acceleration. The feel or resistance was consistent throughout and there was no slop or looseness felt when manipulating it by hand. Since this is a foot manipulated device, I would expect it to have a different feel than a hand manipulated device and therefore might not feel "right" when manipulated by hand. Also, since the bottom of the accelerator is at the end of the arc that it forms when moving from one extreme to another, the middle and top of the pedal would move even less than the 0.5" the bottom of the pedal moves.

Very thorough explanation you have provided for us as I for one have learned more than I knew before. But what are you really saying?

Sorry, thought that was clear, I could not find any dead spot on my vehicle. Never thought it had one.

I also was providing my thoughts on why Sleepy3103 might feel a dead spot using his/her hand rather than foot.

Do you have a standard or auto transmission? I can see how someone with a auto wouldn't notice it. I have been driving standards and autos since I could drive and never had a car this much play in the gas pedal before the engine responds. It makes it hard to get used to starting off and shifting smoothly. I read a bunch of reviews on the Kia and sonata and the reviewers said basically the same thing, this throttle and clutch setup is rage inducing and leads drivers with years of experiance to stall the car and shift rough because it's hard to judge the throttle with so much play and so little resistance on your foot. The hyundais and kias also have a pressure ristrictor valve in the hydrolic clutch system that makes it feel unpredictable and mushy. It's not normal and I will be adjusting the gas pedal to very little play and taking the pressure restrictor valve out so it is more like a normal standard setup. The guys over at the forte forum have been racing about how much better the clutch feels and the throttle is much easier to use. I just wanted to let anyone else who hates this dead spot in the peddle that there is a fix and wondering if anyone with a sonata has done it yet.

Oh and one of the guys over there is a service manager at a Kia dealership and is proving all kinds of help and technical data on it. He said it's not normal and the play seems to be differant on most of his fortes, not the same like it would be if it was intended to be there and properly calibrated. Some have 1/4 inch of play, some have up to 3/4 inch of play. So if your cool with it, then leave it alone.

Just curious, how is braking in my car going to change the play in the adjustment of the electrical leads behind that side cover on the accelerator pedal assembly?
