Elantra MD (2010-15) :: 2013 - Throttle Response Delay
May 7, 2013
I'm getting pretty significant throttle response delay in my 2013 Elantra w/ Tech. It's pretty egregious in stop-and-go traffic when I attempt to accelerate, wait a second before my car responds, and then get jerked forward, only to stop a second later.
I emailed Hyundai and was told to speak to the dealership. I called up the dealership and they had no idea what I was talking about. I emailed another local dealership, and they didn't get back to me. Pretty annoyed at this point.
I did a search on this forum and found some threads discussing resetting the throttle system by resetting the ECM. Wasn't too confident in doing that myself and I didn't want to mess up my car's computer system at all. I'd like the dealership to take care of this under warranty, but if they haven't heard anything about this, then I'm not sure how to proceed. What my next move should be?

I have annoying problem with the car feeling flat while driving it braking into a corner then coming out of the corner I feel I get no response from the pedal unless I push it down further. While pushing down a little further it roars out of the corner. I have noticed it more now because of the icy roads when I have traction control turned off. Push pedal down slightly with no response, then push 1mm further and the tires spin slowly.
I performed my own test in neutral of the auto transmission. While idling at usual idle speed, push pedal slowly and stop, kept doing this a little further each time to see what the rpm was reading. Finally it went from Idle speed under 1000 rpm and shot up to over 3000 rpm? I tried this dozens of times and could not rev the engine to anything between idle speed and roughly 3 grand. Took to dealer "no codes" I believe this will affect fuel consumption.

Feel that VW has tuned down the throttle response of 2.5 I5. Well after having the car 2 weeks now, I don't hate the engine as much, and I don't think the issue I am having is with the engine it-self. In sport mode and tip mode it is much better, Once the car decides to give me what I want, it has plenty power. But in auto mode, It has to do with starting off from first gear at a stop. I really believe it has to be a software problem the way the throttle is mapped in the DBW. The problem is there is little throttle response off the line. Like I push the accelerator down halfway quickly, and the engine throttle opens maybe 1/8 and slowly goes to 1/2 like 5 seconds later. It's more of a drive-ability problem. It's like no other car i have ever driven. If I give half throttle, I expect the car to open to half throttle immediately, and not delay it. I really hope VW comes up with a fix for this, I'm sure it is just a programing problem. So am I the only one?

I've noticed that my throttle response is pretty weak. Doesn't seem to just go when ya put the pedal down. I mean it goes but not as fast as i think it should. is this how it is on all our cars? kinda seems like it has a hesitation or something. Anything I could do about this?

Its been happening to me for a while now, but it seems to be more frequent. ill b driving around casually, go to pass someone or just accelerate hard then quickly up shift and get back on the throttle. I hear the engine begin to rev up again after the gear change but it takes a second or so until i feel the car continue accelerating. also i can feel the haldex system when it switches between fwd and awd or whatever it does. like you can hear it catch and def feel it lurch around. and clutch pedal vibrate a lot when any pressure is applied to it. is this normal?

Picked up the car 5 days ago but noticed when I press the clutch and rev the engine, there's a throttle delay/hesitation and a simultaneous sound like "psshht". The sound is almost like when you're shifting a turbo car with a blow off valve.
Other than that the car is great. 2012 Elantra GL manual ...

I have a 2013 Elantra w/tech pkg (bought brand new) and I have about 106k miles on it. Today I noticed this strange issue where when I let off the gas, it's like the engine doesn't notice right away and continues to apply power. It's only a delay for about a second or so, but it's noticeable enough that I'm writing this. It's really odd and I don't know what to make of it.

I just changed timing belt all accessory belts and water pump on my 2001 Hyundai Elantra. Now the check engine light is on and it is sluggish in throttle response. It sounds smooth. I was quite sure I had the cam and crank marks dead on. I turned it 2 revolutions by hand and they both looked dead on before I started it. If I were off 1 or 2 teeth would that be the cause? And if so how do I fix it? Also will it hurt it to drive it that way?

Resetting Throttle Response. I came across this video, bored and just playing around, and tried it on my 2013.......and it works! Turn the ignition key to the run position, then slowly press the accelerator pedal to the floor. Then let the pedal up fast, then turn the ignition off. Do this 3 times, and on the last time, also turn the ignition off. I was amazed that that the lagging pedal response was almost completely gone!

The throttle response from a standstill seems VERY slow. When I push down the accelerator, it seems to go down a good 3-4 inches before I meet any significant resistance, and even then, I can do a good 2 second count before the engine seems to engage. If I am stopped at a light, and I slightly blip the accelerator, then push the pedal down, it does better. But if I am stopped and floor the gas pedal, nothing happens....at ALL...for at least 2 seconds. It is slightly better when in manual, but the issue is enough for even my wife to comment that it takes off very slowly when you first give it gas.

Uneven throttle response during cold weather engine warm-up? When sub freezing weather arrived a few weeks ago my 2010 Prius developed uneven acceleration during engine warm-up. The car was purchased in October and it ha less than 3,000 miles.
Gradual depression of the accelerator results in a very small, tiny in fact, amount of increasing power to the wheels, not in proportion to the usual smooth and responsive amount of cold starts above freezing temperatures.
Continued depression leads to a point about halfway to the floor when the engine, which of course has been running all along, suddenly surges and the car takes off with a jolt of power. Not smooth, impossible to control well and unacceptable. Many would say this is unsafe.
My 2005 Prius never had, and my wife's 2007 does not have this issue. Could be a cold weather related accelerator defect as with the Camrys, but this is not mechanical sticking as was the case with the Camrys, its an electronics error like a faulty sensor or cold start injector.

I have a 2008 RX350 AWD with only 500 miles on it so far and I am starting to get concerned about what seems to be excessive slipping or a delay in response in the trans. Under normal forward driving the trans seems to shift very smooth. The problem occurs under situations where I am coming to a near stop, basically coasting, and then have to accelerate again to continue forward. This could be in a slow moving traffic type situation or when maneuvering through a parking lot. When I try to execute a small increase in speed the engine revs but the trans doesn't respond.
It's as though it's in neutral and unable to decide which gear it should be in. After a 2 to as long as a 5 second delay it finally engages and moves forward. The condition is even worse if I am heading into a slight incline. Once it is engaged everything is fine and the subsequent shifts are very smooth. When starting from a complete stop it works perfectly. I've never had a transmission slip this much in any vehicle. There was one situation where I was almost broadsided because the RX delayed in moving forward.
I realize this is a subjective call but I am trying to determine what level of slipping in the trans is considered normal under the conditions I've described. I have searched and read past threads about issues with the earlier model years but I thought they were resolved by now. I haven't taken the RX in for service yet but I fear I will get the standard - everything is working as designed - answer from my dealership.

Ive noticed that if I start my car, and put it into drive, there's a 2-3 second delay before the car moves after hitting the gas. It almost feels like the car is stalling, but it's not. It only happens that first time after a cold start.
If I put my car into reverse first, like when backing out of the garage, it doesn't do it. Only when going directly from park to drive. Is this normal?

Well again my celly has died. I was driving down the road listening to some tunes when i noticed all of a sudden i had no throttle response and when I turned down the music my engine had cut out. Well i tried to start it back up and it was a no go. I tested for spark and I am getting nothing, I replaced the main relay and the distributor. I have new plug wires and NGK spark plugs in. This is my main source of transportation so any leads would be amazing. I have a 91 Celica ST with the 1.6 4AFE.

I want to get rid the delayed throttle response on my 01 B5.5 passat V6. I've heard of this "Sprint Booster" product, which seems like it works, although it kills your throttle modulation abilities. I was looking into the Unitronic chip, its supposedly gives 16HP .

My accelerator is very "slowpoke", anything I can do?

We love our Touareg, but one things plagues our truck. There is a terrible lag in throttle response. We press the pedal down some, nothing, press some more, little to nothing nothing (like it is starting to crawl), press some more and ZOOM - the truck takes off. Kinda hard to drive like that... Is this expected behavior or is there a programmer to fix it? We have an 06 V8 and have not had any luck finding one so far.

I am leaving from a meeting with my business partner and taking a left turn at about 10mph and very light throttle due to a rough road. All of the sudden I've got nothing. No throttle response and my car starts chugging bad. Then I see the EPC light on. I shut the car off as it sounds like I have only 2 cyls firing. start her back up and boom, normal again. No power loss, no lights, nothing. I immediately thought water pump. not the case though obviously. From what I can tell the EPC will come on for multi misfires. but for it to come on that suddenly for no apparent reason and then just be fine when I shut off and restart, I would assume this may be an ecu or coil issue.

Went to install my intake last night, got everything in and together, started up the car and it idled just fine. Backed it out of the garage, put it in drive and had no throttle response. I was only able to coast. I did some research and tried replacing the fuse, cleaning the battery terminals and took the K&N intake out and replaced it back to stock. Still no change and still have the check engine light on.

For the most part, I'm pretty happy with my 2010 Santa Fe SE (V6 AWD Automatic).
When I'm coming up to a yield sign, or otherwise slowing down to say 5-10 miles an hour but not a complete stop, and then when I start to try to go again, there is a hesitation and then the vehicle kind of jerks as it starts. It's like it takes a half second to a second for the throttle to respond, and by then it revs higher than I expect. I don't know if it's the throttle delay or a delay downshifting before it starts, or a combination of the two.
I've also noticed that a half second or so delay when just sitting in park and quickly pressing the throttle and releasing. I can press the pedal to about 50% and release it before the RPMs respond at all. Then it'll rev up and back down as you'd expect, just not WHEN you'd expect.

First ever failure with a Toyota. We limped home at 25mph this morning. No response with throttle pedal input, but the throttle body did operate in fail safe mode. Throttle pedal checks out with omhs check across the terminals per Toyota manual. I'm looking at having the car transported 45 miles to nearest dealer. I can change the tb out myself but not sure of the electronics. Does the computer have to be programed for a new tb?
