Pulsing Acceleration

Hey folks,

I have been having a problem with my 2017 Ghibli for the past couple of weeks. When I am accelerating quickly the throttle feels as though I putting my foot up and down on the accelerator even though I am accelerating smoothly (foot down the whole time). Not sure what the problem could be, it only does it when I am sport driving.

Any ideas what the issue could be?

Funny, i've noticed a similar sensation but always think to myself "maybe i shifted my foot in a weird way". Its barely noticeable so never thought much of it.

I have a 17 SQ4 and have not noticed your issue, however, when I drove a 17 base model while waiting for my Ghibli to come in I felt the exact thing. I asked the dealer about it and he told me sometimes the base engines have a stuttering affect when excellerating while the AC is running.
Don’t know if you have a base engine or not.

My 2014 does this, but I believe it ONLY happens within the 1st 5 min of driving or so, when the engine is cold. Because of this I always start off driving in ICE mode and that seems to eliminate it.

My 2014 also does this for the first 5 minutes but like you said its because the engine is warming up. Funny I drive in ICE the same as you do until its warm. Assume its better since rpm's tend to stay down in ice which should be better when cold.

Have a 2018 without this issue.

Are you guys sure it's not the VVT (valve timing) kicking in?

I have an SQ4 and have not noticed it enough to act further. I just wanted to see if anyone had experienced the same thing. I will try and let the car warm up a bit more and see if it still happens.

Thanks everyone!
