2012 5.0 Throttle delay and extended operation

[SixFootSix]

Do all 2012 5.0 Genesis cars experience the delayed acceleration and continued acceleration for two seconds after you remove your foot from the pedal? Does a software update exist that makes the throttle operation more like other vehicles? It is a little hair raising to accelerate out from a stopped lane of traffic and have your car want to race up the bumper of a car in the next lane, even though you removed your foot from the gas pedal. #genesisrookie

I don't recall this as being anything I experience with my 4.6, no idea with the 5.0 though.

Mine does not do that. If I floor the gas from a low speed the car will take part of a second to downshift but once downshifted it becomes a rocket. Lifting off results in an immediate slowdown.

If I give it the gas, but not floored, from a moderate speed it will downshift faster with immediate acceleration. It does not continue to make speed after lifting however.

Mine's the 3.8, and I do recall it being slow to dump the throttle when I lifted my foot. I think there was a flash update the dealer did for me somewhere along the line that helped a lot with that. It's been long enough that I don't remember any of the details, though. It seems to me that the update wasn't exactly described as what I was looking for, and the dealer was sceptical, but after I showed him some posts on here, he applied it, and I think it helped. This would have been a couple years ago on this board.
