Hesitation/Rolling Stop Problem

[Analog]

My 2012 had the same hesitation. It doesn't any more. There *is* a fix. Just search for the discussions about the air box flapper door.

Given that the loaner driven did not have the problem it's reasonable to conclude this problem is not related to the gen 1 issues with hesitation. I've had both and the gen 2 has none of the hesitation problems the gen 1 had (and I experienced, down to the letter.)

While some parts of the description are similar (rolling stop) there are enough different parts (lane changes, smooth starts, accelerating out of corners) that it seems different. Plus the shop techs should know about the gen 1 issues, heck that might even be part of why they wanted data logging.

Fantasia, there just has to be some similarities that you are missing. You could probably see them if you lined up 5 or 6 video snippets in a row. If not, post 'em here!

mfrish - is yours a gen 1 or gen 2?

Fantasia - is yours AWD or RWD?

Hi all, and thanks again for the information.
I did suggest the accelerator pedal sensor replacement however that was not taken as a solution. They were receptive to me driving a loaner and provided a new Genesis which we drove for two days without any type of incident. It was completely trouble free and a pleasure to drive. Unfortunately since returning to our car, we have continued to have the same problem. We have had several meetings trying to come up with a solution and hopefully this will work itsself out. Thanks again, and will let you know how we make out.

You might want to check your taillights to see if you have any condensation in them. See posts regarding this recall and how it effects the transmission.

Mine is Gen 2, AWD (will have to add that to my signature )

Agreed - this sounds like the symptom that the recall is about. I myself haven't had this but will be more diligent. I wonder if the condensation is visible or not?

I don't have any condensation in mine but I would think it would be very visible if present.

As a preventative measure, should I tape around the tail lights if I'm going to be driving in the rain?

What is the build date of your car?

I've had this issue as well. It is ALWAYS when taking off, mostly on an uphill leaving my neighborhood, onto a main road. Of course I need instant response and acceleration to get into some fast moving traffic.

I have found that if I turn off the traction control, I have ZERO hesitation. I'm due for service so was going to have dealer address issue then.

I've seen the problem occur a couple of times with my 5.0. I've attributed to transmission logic as the car seems to take a fraction of a second to decide what gear it wants to be in.

Gear selection is such a complex process with so many sensors providing input I can see where a certain set of circumstances would cause a problem.

If you can replicate the circumstances under which you experience the problem or eliminate some where you don't it might make it easier to explain.

Of course, if your normal route causes that set of circumstances to occur you could expect the problem to surface frequently.

The build date for mine is Oct 11, 2014. I guess it's been on the lot for a while.

Mine was built in July and I have no issues. If you don't visually see any condensation then I wouldn't bother putting tape on it.

I know this thread has been dead a while, but just purchased a 2015 Ultimate about 30 days ago and it has the same hesitation that is discussed here, so was wondering if anyone was ever able to get resolution with the problem

Hi
I am a newcomer to this site, referred to by a friend recognizing a problem that we were experiencing with a 2015 Genesis.
We took possession of the 3.8 on January 19 of this year and within the first couple of days started to experience a hesitation with acceleration. It is like a dead spot where the pedal is depressed and nothing happens. This hesitation was random, would sometimes occur coming out of a turn and has also occurred when doing a lane change. We have also experienced this hesitation when coasting up to a red light and before coming to a complete stop, stepping on the pedal and having nothing happen. A second or two later, it seems like something catches up, and there is this surge of power.
Interestingly, this is our second Genesis. We leased a 2009 with all the luxury packages and were extremely happy with it. As a matter of fact, we were so happy with it, we ended up purchasing at lease end and drove it for three years until trading it in on the 2015. The 2009 was trouble free and we never experienced any hesitation problem, although research on this website seemed to indicate that this was a problem on many 2009 to 2014 Genesis models.
Naturally the 2015 has had several visits to the dealerships, some for overnight stays. It has had "black boxes" installed to monitor our driving habits. We have discussed my two feet driving style as a potential problem, however have not been able to understand my wife's one foot style while also having the problem. Dual mats have also been considered.
They have not been able to say what the problem is, although it has occurred on one occasion with the service manager in the car.
I am at wits end with this situation primarily because of the safety factor. It is something to consider when making a left hand turn or a fast lane change not knowing if there will be a hesitation in front of oncoming traffic.
A little wordy this is, however I wished to state my case and see if in fact as we are being led to believe, that we are the only Genesis owners in the universe having this problem. Any feedback would be greatly appreciated.
Thank you,
Bill

I am having the same problem with my 2013 genesis Sedan. Makes you wonder if you are going to get run over. Not a good feeling.

I have this issue. I have tried everything premium fuel, a “Sprint Booster,” traction control on/off, you name it. I have the 5.0 Ultimate, and it does not have the air flapper. This only happens now and then and it’s scary. You need power. You count in it. You punch it, and nothing happens......you wait to get hit.
