Santa Fe (CM - 2007-12) :: 2010 - Engine Hiccups / Quick Hesitation
Mar 23, 2015
I've got a 2010 Hyundai Santa Fe with the 2.4L engine. Funny thing happened on the highway. Driving along with the cruise on, the engine 'hiccups'. Almost like a quick hesitation or someone lightly tapping the brakes.
Got it home and ran the usual tests. Computer showed no trouble codes. Checked the oil. Checked the air filter. All normal.
Turned the car on and tested it in park. Gave it some gas, and took the engine up to 3k RPMs...after a few seconds, it did the hiccup thing again. I watched the RPMs dropped from 3k to 2.5k, and then rebounded to 3k. We could also hear a slight and single 'knock' each time the RPM's would drop. I noticed the A/C was on, so I turned it off, and the problem went away. Turned the A/C back on, and the problem came back. I did that about 5 times to confirm it, and every time the problem occurred, the A/C had to be on.
Now, of course the car has 61.5k miles, and we're the second owners, so bye bye warranty. The car was in for repairs at the dealership when the head control unit for the A/C had issues. Of course now we ask them if the problem is related to their repair will they cover the costs, and they say the best they can do is ask Hyundai to cut down the expenses (even though the repair was done within the last 10k miles)?!
My guess is the compressor has kicked the bucket. Of course, I'm not sure if maybe it's the idle motor not operating like it should or if the car even HAS an idle motor to work with the RPMs when the A/C is on.

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.

2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?

Seems like the engine and transmission are talking through Google Translate. The usual problems: too quick upshifts, too slow downshifts, lugging and vibration at RPM too low for road speed around town, hesitation. Aware this all supposedly support mileage but it's putting a rough edge on an otherwise quiet and likeable car. In fact, mileage seems to be suffering a bit. Aware there's a TSB on the 6AT that supposedly cures this via a software update .

A demonstration of how the Airlift tool spares you from the hassle of burping the system and attaching a hose to the top air vent on the engine. Done on a 2010 Prius but it applies across the board.

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.

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.

I've noticed that on cold starts after work, or in the mornings in start up my Santa fe's really rough at idle.. I'd like to say even slight hesitation when I take off.. I notice a drop in RPM and lately harder shifts out of first..
My sf is the 3.5 AWD w/ nav it's a month old with 2900 Kms on it..

I have a 2010 Santa Fa GLS. 88K miles. This issue started in the last 6 months, once the engine turns over the RPM drop low and starts to putter as if it is not getting enough fuel. If push down the gas when starting it works. Once it passes the first 2 -3 seconds everything is fine. No issue idling or driving. What this could be? It's not an issue with Starter, Battery, my best guess would be a sensor, leaky fuel injector.

I bought a 2010 Hyundai Santa Fe 3.5L and noticed the engine would jerk really bad. It felt like the engine was going to jump out of the vehicle. I notice it does it when I turn it on in the morning and when I am driving slowly out my lane way the engine jerks. I have dealt with this problem since last year and they have already replaced the transmission which has done nothing. I took it back to the dealership and the service manager told me that he has already had 4 of the same vehicles come in with the same problem and they realized that they had to re-set the computer in the engine so that the transmission computer and the engine computer are on the same page that they talk to each other so to speak. Since they re-set the computer we have had the vehicle back a week today and this morning the car jerked again. I am tired of constantly taking this vehicle in and being told they have a solution and then it is not fixed. How am I supposed to sell a vehicle to someone when it feels like you are being lifted out of your seat because of the JERKING!!!!!

2010 Santa Fe V6...about a week ago the starter started acting up. When you try to start the car, you would hear 3 clicks before the engine would start normally. The clicking is random and does not happen every time. The dealer could not find anything wrong other than the battery was reading 440CCA vs the 600CCA it was rated. Starter clicked first thing today on the way to local mechanic to get brakes replaced. They tested battery and it tested good. What could be the problem?

I turned off the engine and I get a whirring sound, quite loud, that seems to be coming from the top of the engine around where the injectors are.

I took my first road trip with my family in our new LS460L up through Donner's Pass and into Reno. This car just gobbles up miles. But what I did notice is that going through the mountain pass, the car barely hiccups through the curves and hills. Before you know it, you're pulling lateral g's.
The other thing I notice is that it's really easy to get comfortable in this car. It's just pure smooth silk. Makes me want to go into a trance. I'm not talking about the crap that BMW drivers throw at Lexus cars about detachment etc. Personally I love the smoothness.

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.

I've been having some trouble with engine hesitation after driving for 15-20 minutes and poor MPG on my 2004 Hyundai Santa Fe 2.7L. I've been slowly running through some tests as I learn how to diagnose car troubles. I just ran a voltage test on my 4 O2 sensors using a bluetooth scan tool and the Torque Pro app. I ran the tests at idle after warming up the engine. To me, the upstream sensors seem fine but downstream sensors are not behaving like they should. Aren't the downstream sensors supposed to be relatively flat around .45 volts while the upstream sensors fluctuate steadily between .1 and .9?

Over the last few months I was having a problem with my 2002 SC430 with 130,000 miles having random hiccups and engine hitches during acceleration and even at random times while on the highway or around town. My average 10 minute trip around town would have at least 10 hiccups, all random and during no specific style of driving. No one wants a stuttering engine!
After reading some of the threads here there were several options...
1. Do a system reset by using only the key turned on and pressing on the gas pedal for thirty seconds. While optimistic, this didn't solve the problem...
2. Many threads suggested that it may be my TPS (throttle position sensor) so I started shopping around for a sensor to install myself. They run for about $75 online and are a pretty easy install..but I wanted an official opinion so I went into my local lexus dealership to ask them if this was the best course of action...
The solution: Apparently, the 430 engine is a notorious carbon producing engine so, as my local lexus mechanic explained, this carbon can build up in the throttle body, affecting how the mass air flow sensor (MAFS) is read. My mechanic recommended having a FUEL INJECTION SERVICE. This service cleans the fuel deposits in fuel injectors and carbon build-up in cylinder heads and in the throttle body plating.

My year-old Camry hybrid stalled out last night. It was the second time this has happened. The first time, about a month ago, I made a quick start from a light, followed by a quick stop, both actions to avoid an accident. (I was about to get rear-ended and scooted into the intersection to give the guy closing in my mirror more room.) After the stop, the car had no power but it started up, no problem. Last night, I was about a minute into my trip, stopped at a light, and the power just died. Again, it started no problem.
This time I noticed that the radio went out. Not sure about the headlights. The emergency blinkers came on at the touch of the button before I restarted. In both cases, I stepped on the accelerator and got no power. Took it to the dealer and they couldn't replicate the problem, of course, and whatever interrogation they did of the systems found no faults. They had to be convinced that I knew the difference between an actual stall and just going from gas to electric. It's kind of disconcerting to just stall out in the middle of the street. And I'm concerned that this is a problem that could get worse -- probably just after the warranty lapses.

I am hearing a new beep sound (It's a quick double high pitched beep) when I start my car. What it could be? I do not see anything that indicates there is an issue with the car (i.e. no warning lights) but it double-beeps every time I start it now.

I just purchased an l/certified 2013 RX 350 (34K miles) this past weekend. I did not notice these issues on my test drive. I've started to notice that when taking my foot off the gas pedal (while not resting near the break pedal) the vehicle goes through a series of easy coasts and then some resistance (as if using an engine as break on a truck with a manual t,) then returning to a smooth easy coast.
I've also noticed that when accelerating at a slow speed from stop (I'm in traffic) there is a bit of a hesitation, like turbo lag, yet this has no turbo. The lag seems to be there even if I want to accelerate aggressively.
I hate to get tied up with a dealer service department already.... "Cant duplicate," or "that is normal operation," or "Computer codes check out." Looking for reinforcing information so I don't have to take it in once a month for an unknown amount of time.
Of our three other cars (2015 Prius, 2002 Nissan Altima, and (pre-tran fail) 2002 honda odyssey) none experience anything like this.
Our household is dumping a 2002 honda odyssey for repeated transmission failures never covered with goodwill. All service was at a h dealership and manufacturer schedule was followed. I'm already sensitive to the manufacturer/dealer relationship.
