V6 Throttle response issues

[VaiFan]

Okay, I wonder if anyone else is having this issue.
I have owned my Genny since October. I have almost 5k miles on it.

When taking off from a standing start under moderate driving conditions, it starts to go, slowly, then hesitates a bit, then it seems you have to give more throttle to get it to go, and it suddenly lurches forward a little to harshly.

I can't tell if it's the transmission torque converter or the actual throttle and ECU trying to figure out what to do?

I'd like to hear if anyone else is experiencing this?

Hopefully someone will have an ECU reflash soon that will spice things up a bit.

I think I've experienced what you're describing. When coming from a complete stop it feels like the ESC wants to see what happens before it really lets the power go. I've become used to it, and I'm not really an aggressive/hard driver most of the time anyway, but in those occasions where you really need to punch it to get out into a heavy flow of cars from a dead stop, it always seems very hesitant even though there is obviously plenty of power. Once it get's just a little speed it then steps right up though.

From a dead stop at a red light and stomping the gas going straight, I haven't experienced this - the car just GOES. However, I have noticed major ESC lag if trying the same thing while turning right - and this is exacerbated if a height change is involved (i.e., a right-hand uphill turn from a dead stop). The amount of hesitation in that circumstance borders on dangerous, if trying to beat traffic. Of course, I've adjusted my driving accordingly...

For me, when I need to go and I put my foot in it, it just really goes.
Very nice!
It's when driving moderately that I'm describing this issue that I seem to be having.

Haven't experienced this since the transmission "learned" my driving style, though it was a bit "jerky" and definitely not smooth at first. Could this be what you're experiencing? I'm not really sure how the transmission shift algorithum does it's thing - hopefully, one of the more tech-savvy types can elaborate on this.

I have noticed that, unless I really punch it, the transmission shifts from first to second and from second to third way too early to really use most of the torque band, which makes it feel quite slow and sluggish.

I'm thinking that's probably a fuel economy thing but it does require a lot of getting used to.

Dont try to change your driving habit too much as the transmission "learns" how you drive and adjusts its timing to you.

I don't think it's the transmission. It's happening in first gear.
I think it's something in the ECU throttle programming.
Or, the Torque converter winding up.

From what I've seen, it seems that a lot of the newer six speed transmissions end up with some sort of "hesitation" feel because manufacturers adjust the transmission shift programming to try to improve the gas mileage. The amount of hesitation varies across brands but this complaint seems common.

We have a fairly new vehicle that had it pretty bad. Bad enough where the manufacturer did issue a flash to try to make it a little better without compromising the MPG. I got the flash and it was better, but still a bit of a nuisance. Then they came out with an optional flash which really improved it a great deal. It was optional though (not standard issue) because they warned that you could get up to a 2 MPG drop. I went for it anyway. I figured it didn't have the world's best MPG to begin with and I'd prefer to just have it drive the best that it could. I'm happy with the way it shifts now. It's more than good enough and certainly not annoying anymore.

From the sounds of it though, the Genesis' current hesitation isn't as bad as that was, but if it bothers people enough and they complain about it, Hyundai might put out a tweaked flash update.

I've experienced this on the Genesis - was also a characteritic of my '02 Sante Fe and the loaner Sonota I've been driving. It never did really go away in either vehicle. To some extent I think it's one of those perenial Hyundai characteristics (for better or worse) across most of their vehicles. I learned to basically be very gradual with acceleration and not put myself in a situation where I needed to floor it. I understand the Genny engine is a tweaked version of the engine in the Sonata (?) so not surprising they would both exhibit the characteristic I guess...

Sounds like you're driving my '06 VW Passat 3.2! This was a common complaint among owners which VW addressed with a flash. It helped, but never really solved the hesitation which was most pronounced when starting forward from a stop sign. Some people swore that driving with the Tiptronic (Shiftronic in Hyundai) for a few miles reset/improved the function of the automatic. Others, including me, swore that coming to a complete! stop helped more... that the hesitation was because the car hadn't actually shifted to 1st from 2nd.
Anyway, I think you're right that this isn't Gen specific.

Meant to say 3.6 Passat, not 3.2

I have not had any problem such as you describe. The acceleration and shifting on my car are excellent with no problems what so ever.
