I have been getting really bad hesitation when trying to power around something. It is so bad when I floor it that it feels like I am hitting the brakes, bucking comes to mind, repeatedly when trying to accelerate. Eco mode is off and I use chevron mid grade at all fill ups. Should I go to the dealer and if so what should I tell them to check?

Mine does the same thing.

Hyundai do not have a clue what is wrong. Or maybe they do and are ignoring the issue.

Take it to the dealer. The more people that report it the better.

They kept my car for 5 days and all they did was check the spark plugs!

The only thing that gets rid of most the hesitation/surging is the list below in my sig \/ and apparently a tune-which I cant speak for. My car is so much better after the vacuum hack too...but you have to have an aftermarket BOV.

I think I need to read up on the lemon law. I did not purchase a turbo car for it to buck on me and I should not have to put after market parts for it to drive as expected. This seems to be recent. Did not do it when my dad took it joy riding when it was only a week old.

OH NO do I sense buyers regret???

I was going to ask if you tried the airbox flap mod?

I would be rather give the dealer time to look at it first before trying that. I heard something while driving about an hour away from my house and that is when this seems to have started.

Do the flap mod and use high octane gas 91/93. I had this hesitation as you describe. By doing just these two things. It made a huge difference in my case!
I had to power around a log truck a few days ago on a two lane back road. Th VT did it without all the bucking. It performed so well. I didn't realize it , till after I passed the truck that the car didn't buck.

I'll give it a shot after I do my programming for the day. Do you put the magnet back in when going in for service? I have an oil change coming in 500 miles.

I doubt they will even notice.

Nope..my car was at the shop all last week for other issues not related to engine. I plan to never put the magnet back in. lol

Cool thanks guys. I'll update the thread when I do it tonight. Hopefully those 2 riced out vtech civics are doing runs when I take her out to test.

Check for boost leaks if it happens all the time.

I think you're gonna be disappointed.

The poster's do not acknowledge you are driving a NA and nothing is the same as the Turbo.

The throttle is "drive by wire" so there will necessarily be a response time. Can't be helped.

The motor is small, so expect lagging response.

The "flap mod" is all in the head. I did the flap mod, and I even went as far as removing the stock airbox and putting on a cone filter and guess what? I can easily replicate the surging that the flap mod "fixes".
Changeing octanes will more than likely not fix the issue either. The VT was designed with 87 in the tank, I've run both 87 and 93 and could not tell any noticeable difference between the two. I know there are minor power differences between the octanes but I wouldn't think it would fix the current issue.

It seems the people having this issue have the automatic transmission (I could be very wrong here). My guess is that it has more to do with the transmission side rather than the engine.

But a question: when you say "power around something" do you mean you are trying to power around a sharp corner? or do you refer to going straight down the highway and power around another vehicle?
If you mean powering around a sharp coorner, I would say it is more the stability control kicking in. If it is the latter then my guess goes back to something with the transmission or the transmission computer. I would almost say try replicating the issue using various combinations of Eco Mode on/off and the Stab Control on/off and see if the result vary.

NA doesnt come in Matte Gray does it RD?

I do also agree with the OP that we shouldn't have to mod the car to make it drive correctly.

I have an automatic turbo. Did not realize nav's came here. When "powering around something" I mean trying to get around a truck or something large. I think everyone can agree that you want some on demand horsepower to get out of the way of something if need be. I usually drive with the stability mode on.

what you seem to be describing in my other cars is when the transmission is trying to figure out what gear it should be in. Sounds like you are in 6th gear, cruising lets pretend at 60mph, truck is going slow infront so you mash the gas and try to go around it? Sounds like the tranny is having issues trying to figure out wtf you want. in situations like this (my gtr kinda does the same thing in normal mod 6th gear low rpm cruising) is to just manual mode it for a second and drop the gears as you go around, then hit the shifter back into automode.

i bet you would have a better transistion of power if you slowly pressed down on the gas. the bucking i think is from the engine trying to go ( you are flooring it) and the transmission not being in gear so power is going in and out, and then during this time its possible your slightly slowing down, causing the ECU to freak out on which gear to pick.

Then for sure try it with the stability OFF and eco OFF. Then come back with us

I completely agree with you kcc1982 about not needing to do any mods to get what you should get out of a stock VT. I have yet to acquire my VT and really haven't truly experience anything other than working on Keith Stone VT (plastidipped his wheels), and receiving my solo exhaust + Turbosocks FMIC kit. And of course here. Haven't even went to the dealer to test drive one because I might just bring it home lol which I can't do right not (blah blah blah). But one thing I have noticed is people talking about the hesitation. So I guess I can expect that when I first get my VT though it might be different because it will have a manual tranny rather than auto. But soon after I acquire my VT it will have must bolt ons and a tune. So thank goodness for that. I can't wait to experience all the little things with the VT

Also, My wife has a auto 2.0T 2013 sonata and there is zero hesitation. that baby can FLY. I love it. I would expect nothing less from the VT auto or manual. Weird.

That totally makes since.

Sometimes when you are cruising and you suddenly floor the gas pedal you can tell the rpm goes up for a second then you notice it rev high like it finally dropped a gear.

But like what bhk1004 said, why won't you just hit the downshift pedal behind the steering wheel to drop the gear on your own command rather than just flooring it and expecting the computers to read your mind and finally gets what you are trying to do and drop the gear for you.

I am not 100% for sure about the VT's auto, but the wifes sonata has pedal shifters on her steering wheel column and I have used them to down ship to get the rev up quickly to pass someone up. try that as well.

also remember boys and girls. this transmission is from the accent. its not exactly a highly engineered product. try to help it as much as you can.
