Santa Fe (DM - 2013+) :: Hesitation / Idle Dips Up And Down
Jan 15, 2017
My 15' SFS 2.4l has been doing this since around the 10,000km mark, it now has 26,600Kms and it seems that when I come to a stop at a light the hesitation has gotten worse! When I mentioned it the first time to my Hyundai dealer they said on one of my oil changes they would put in an additive to clean the injectors (I said it shouldn't be doing this as it is a brand new vehicle) and now other the last 16,000kms since the additive was put in I'm finding it is getting slightly worse. The idle dips up and down a very Mina's amount resulting in almost what would be a cat purring sort of vibration (weird way to describe it) but that's honestly what it's like. I checked to see if there was a cat stuck under my hood but their was nothing (I'm kidding).

Loving our new SF, but have noticed a problem periodically when starting out from a dead stop. When the accelerator is pushed, sometimes there is a hesitation in the engine. Almost feels like the gas has been restricted for a second, then it engages and goes. I've notified the dealer and plan to have them look into it at my first oil change, but it is happening more frequently and think it may be something I need to get looked at sooner than later.

I purchased my 2013 SF 2.0 Turbo SE in August 2013. Up until then, I was a long time Toyota owner. I've very satisfied with the SF, except I've been having an intermittent issue since I bought the vehicle.
Maybe 3-4 times a month, out of the blue, when I making a left hand turn, there is a hesitation when I press the accelerator. The hesitation lasts for about a second or so, but when there's traffic coming at you while you're making the left turn, it can be quite scary and the second feels like forever!
The hesitation feels like there is absolutely no power and the engine will stall. It never does. I've had it back to the dealer/garage for diagnostics several times but they can't seem to find anything wrong. And they keep charging me for the diagnostics! This occurs in ECO mode and non-ECO mode.

We have a brand new 2013 Ford Focus, a little over 2500 miles. We drove the vehicle to NYC, starting the trip with over 500 miles. During stop-n-go driving the following conditions are experienced: - car in drive but stopped, engine idles at 750rpm- car moving at crawl speed, less than 5mph, and RPM between 750 to 2100, engine acts as if it will stall (IT IS AN AUTOMATIC TRANS); when this happens there's an obvious shudder - again almost as if the car will stall out- cannot determine what gear its in, but probably first, second, or maybe third, but no higher
We took the car back to the dealer, but they acted as if this was a normal, if not, non existent issue; they were very dismissive.

I have an 07 with the 3.3L and on start up the engine runs really rough and while driving when warm it keeps losing power with a regular rhythm. It almost feels like and injector or ign coil is dropping out. I have no CEL and have recently changed the spark plugs and rear upper O2 sensor.

I'm looking for an exhaust system with a quad tip. Also looking a that low grumble while in idle.

It'll do okay when I am not flooring it, but when I do floor it there's a pretty noticeable lag and then VROM it'll take off like a bullet... This car has a manually operated throttle control, are there any adjustments I can make to make the truck more responsive? 2.4L 4Cyl....

2003 Santa Fe GLS 3.5l with 170k.
Been working OK up until about 2 months ago when I would notice a brief hesitation every once in a great while when driving. It became hard to start - would crank well but just took about 5 seconds to finally start. Recently, I was on the highway and it jerked at about 65mph but did not cut off. Once when I was at a traffic light, it shut off completely but started right back up again. I was convinced that it was a crank or cam position sensor as I had dealt with a similar issue with another car years ago. It also seems to start right away when the temps are in the single digits - when they get higher than 25 or so, hard to start again.
I bought a new crankshaft position sensor because all the posts I've read point to that being the problem given the symptoms. I haven't installed it yet - still looking into this and wondering where it is! I'm thinking that it might be more fuel-related now though because after I started my car after work yesterday (it went all day without being started) it was hard to start but this time it was if I hadn't started it in 3 weeks. It kind of sputtered until I gave it the gas enough where it would settle out. Fuel pressure regulator? I hadn't thought it would be fuel-related (pump, pressure regulator) because 99% of the time, the car works just fine.

Our 2015 es350 with 2,500 miles hesitates when accelerating from a dead stop, such as from a stop light. We are told this is to be expected with this vehicle. The dealership test-drove the car and say there's no problem. But this hesitation is unlike any other car we've experienced.

My car has the wavy acceleration feel and sometimes hesitates a bit. It is way worse when the a/c is on. I wonder if this is a octane or spark plug issue. On my old cruze 1.4t the gap was wrong from the factory. It came with all four gaped under .022 but the manual called for .028. Everyone gaped to .035 with great results. Checking the spark plugs?

I have been experiencing this one for quite a while now. The car is a 2003 GTI VR6 24v. It is stock other than a 3" hole in the bottom of the airbox to pull in cooler air.
When I am sitting in traffic, and in 1st or 2nd gear, keeping a consistent speed (10-15mph) and application of the throttle (not moving my foot at all), the car sometimes just decelerates/hesitates/bucks a little by itself, and kind of feels like it is hiccuping or not getting enough air or something.
At high rpm, or in any gear above 2nd, I don't feel the hesitation and the engine runs great and pulls hard. No MIL lights on the dash, and no other problems with it.
Is this normal for manual VW's? Or maybe the hesitation coming from the engine not getting a consistent airflow from the hole in the airbox?

2003 E300. For a while I have experienced intermittent hesitation and I just put up with it as it was only a bit annoying. It has since worsened to a lot of hesitation and lurching, to the point where, at times, I'm concerned about stalling out and/or getting rear-ended. I took it to my dealer. They installed and ECU update. However, that did not solve the problem. The service manager said that it is an "inherent condition" and it is operating as designed.

I have a 2009 Santa Fe Limited with 47,000 Km on it.
Over the past 2 weeks I have noticed that when I go to start up the car, the ignition doesn't sound the same. Meaning, that typically when I start the car, I hear a quick turn of the ignition and away I go. When I now start up the car, the ignition does not turn over as quick and I'm now hearing a bit of a hesitation.

Purchased this vehicle new in Dec. 2011.Within a day or so,I noticed a hesitation when completely stopped and waiting for traffic to pass to make a left turn.
I started to proceed for this turn,but,no power when I slowly accelerated. All of a sudden,big surge of power ! Went to the Dealer to check this out.They said they drove the car for 7 miles,checked it scanner,etc.,but could not find the problem.

Santa Fe - 2004 - 2.7 liter automatic fwd.
I am experiencing an occasional jerking or hesitation while sitting stopped at lights and it also has a tendency to do the same as I begin to move from a stop at times. It almost seems like the transmission slipping or something but likely more engine related I think as I am at a stop. I have felt this slightly while at speed as well but not that often, at least not yet. It also seems more noticeable as the weather get warmer as was very noticeable late last summer and did not present itself again until spring.
Also-I have read that some threads re stalling issues(not exactly what I have) that can be related to the crankshaft position sensor and also read somewhere a while ago about an issue re the ecm needing reprogramming but have not found that recently.

I just picked up a 2004 Sante Fe with 150K for my daughter. "she loves it" I love to work on cars so didn't mind the mileage. I have shifting issues so I replaced the input/output sensors, when I started driving it it was back to what seemed normal with a little hesitation between shifts, now it's back to lunging while in 3 or 4th gear. Strangely to me the shiftronic works great without issues.

My 2009 awd SF is less than 4 years old and has about 81500 km on. In the past few days, I start to feel a little hesitation while starting the car. I have an incident today in which the car barely turn over - behaved exactly as if the battery is dying. Took it to the dealer and spent 55$ for a diagnosis => alternator is OK (what a relief) but the battery is weak. I do not think battery would die (stop holding charge) this soon. I expect at least 5-6 years of service from a battery.

Last night i noticed a slight hesitation during acceleration. Today i had driven around in town for awhile and did not notice any hesitation. When i got onto the interstate I pushed down the peddle to pass someone and it did nothing, I let off the gas and back on and the car bucked pretty bad. All the way home it has issues when I pressed on the gas but did fine at cruising speed. I would think a fuel filter would have been a slow progression issue so I am thinking maybe it is a sensor. I sprayed carb cleaner around vacuum hoses today and did not notice any surge so I think I eliminated a vacuum issue.

A friend of mine has a 1989 240 I'm trying to get road worthy so he can sell it. After regapping, cleaning intake, cleaning idler, new sender, new in-tank fuel pump, and new MAF (all needed to be replaced) the engine still has issues accelerating from idle.
Did the usual diagnostics (#2, #6 LED flash modes). Even took apart the throttle body sensor to make sure that was functioning.
Idle is good and smooth. If I slowly open up the throttle the engine behaves well enough, but if I ope up the throttle to, say, 1/8th from idle the engine will hesitate POORLY. I can even make the engine die. I can drop the throttle to zero and rev back up fine so long the revs don't go down to idle. I made double-sure the throttle sensor clicks from the idle position (the sensor just has two spst switches to detect zero and high throttle).
Engine sounds fine otherwise. No problem opening up to full throttle once I get the revs a little above idle.

A problem just popped up yesterday. 09 Camry, 2.4L, SE, about 178k on the odo. Started out as a slight hesitation when trying to accelerate from a stop, hardly noticeable, in the am. As day progressed it got much worse (very little driving but about 3 to 4 trips). By night the car wants to die upon first start up. Engine will rev higher, then drop, then rev, and will drop way low and stutter and die if I don't feather gas. Very bad hesitation today when trying to get moving. This morning it was revving high, low, high, low (high meaning a little over 1000), then dropped, stuttered and died. Cranked again fine.
My in gear idle rpm is about 650. I will be checking the plugs and throttle body later today as several months back I had issues that seemed to be related to those. I have my suspicions, but want to get opinions. I filled up the tank yesterday morning. Was about 14 degrees yesterday morning, warmed up to around 30. In the 40s today. Engine does get to normal temp, all that fun jazz. I am thinking shitty gas....?
