Santa Fe (CM - 2007-12) :: Rough Idle And Low Speed Driving

I have a 2007 2.7-liter Santa Fe with 71,000 miles. I experience intermittent rough idle and rough low speed driving. It seems that in town driving will trigger these conditions. And when it's warmer outside that oppose to colder temperatures.

In most cases I can turn the car off, and after 2-5 minutes, start it right back up and the problem with go away.

The OBD codes are P0276 and P0306.

I have replaced the coil and injector on #6 cylinder.

The #6 spark plug is dry when the problem occurs.

I had the dealer update the ECM software

Santa Fe (CM - 2007-12) :: 2009 - Rough Running And Won't Kick Back At Speed

I have a 2009 SantaFe Diesel and am having a few issues.

Firstly, of late it has been running rough when I back off the accelerator but hold the current speed. Almost like a mis-firing feeling. AT about 1500 RPM

Secondly, I was driving down the freeway recently, the car started to labour going up a long hill, so I tried to kick it back a gear using the accelerator but it wouldn't do it. It stayed in top gear and struggled. I had to manually do it with the gearshift.

About 12 months ago, I was having problems with the car completely losing power on a quick takeoff from standing still (say at a roundabout) but that seemed to fix itself.

Santa Fe (CM - 2007-12) :: V6 Rough Idle When Cold

I have a 2007 SF 2.7L V6 with 55000km.

Recently we have noticed that from a cold start the engine idles roughly few a short time and especially bad if put into gear only moments after starting.

Do we need to let it warm up for longer?

Santa Fe (CM - 2007-12) :: 2011 Limited Reluctant To Start

I drive a 2011 Limited. Three out of the past four mornings the car has been reluctant to start. It is cold out, but not super cold. This morning it was 1C (34F).

When I turn the key, it cranks but does not fire. I Held the key for what felt like forever, but in reality it was probably only 6 seconds. I let go of the key, waited a few moments and then tried again. After the third try, it finally fired and ran normally. It didn't stutter or otherwise seem to have any problems.

At this point I went inside and found my basic scan tool. No codes were stored and the voltage was between 13.5v and 14.6v. After I drove to work, I turned it off. The voltage dropped to 12.1v. When I cranked it again at work, I saw the voltage drop to 9.5v for a second before it fired up and jumped to 13.5v, then 14.6v.

The car has the original battery. Could it be as simple as a battery? Oh, I Just remembered, when the car did start, the radio was off. Upon turning it on, it was reset to defaults. Other than this starting issue that has only recently started, pun intended, and the radio I am having no other issues with the car.

Santa Fe (CM - 2007-12) :: 2008 Limited - When Accelerate Car Seems To Pull To One Side

I'm noticing more and more on the highway when i accelerate that my car seems to pull to one side then when it shifts it snaps back. I'm not really sure if i'm even describing a transmission issue or a power steering issue. Basically, it just seems to pull and snap back fairly strongly, enough to cause a slight swerve as it shifts during acceleration. (No error codes or check engine lights)

Santa Fe (CM - 2007-12) :: 2009 - Rough Idle / Random Stalling

I am happy to own a Hyundai Santa Fe (2009) 2.7l which originally originated in the US. It is a really nice car, however, it recently over time developed the problem, which causes some pain - firstly it started with rough idle (pulsating), now it began to stall from time to time when decelerating.

[URL].....

I tried to plug a OBD reader and here's what I get (well, that's a "pending" fault, but still might be useful).

I tried to browse around the internet. I believe it is unlikely that 2 oxygen sensors fail at the same time. It could possibly be caused by vacuum leaks or faulty MAF. Is it a common fault among Santa Fe?

Santa Fe (CM - 2007-12) :: Engine Running Rough Idle And Hesitation

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.

Santa Fe (CM - 2007-12) :: 2008 - Rough Idle And Engine Seems To Shut Off Without Any Notice

I have a 2008 Santa Fe 2,2 CRDi that recently started to behave bad. When cold it starts but runs only for a few seconds before it dies. The engine seems to shut off without any notice. I am able to start the car again straight away, but the same thing happens.

If I try to push the throttle I might be able to keep it running for a longer while, and it seems to improve as the engine gets warmer, but it still dies after a while. (Some minutes.) When running, the engine feels kind of rough (hard) and not a smooth as its supposed to be.

I have cleaned the EGR valve, and replaced all the injectors. I also checked the diesel filter for water and flow, but didn't replaced as it was changed this summer.

The car is a no runner as it is now, since the uncontrolled shutdown of the engine makes it danger to use in the traffic.

Santa Fe (CM - 2007-12) :: 2011 Limited - HVAC Blower Doesn't Turn On From Time To Time

Over the past year we have been noticing that the HVAC blower doesn't turn on from time to time. All settings in the control panel seem normal and the fan speed is turned on. Most of the time everything is working normally, sometimes when the car starts the blower isn't working and then starts after a minute of driving. Sometimes I notice the blower isn't working and I turn up the fan speed and after a few clicks it starts working normally for the remainder of the drive. And then sometimes the blower doesn't ever start and I need to turn off and restart the car a few times. When the blower hasn't been working the a/c compressor has been turning on, something in the blower circuit is failing.

There are five possibilities:
The HVAC controller isn't telling the blower to turn on
The power relay isn't always working
There is a wiring or connection problem
The blower motor itself isn't working
The power mosfet is failing.

What needed to be replaced?

Santa FE SM (2001-06) :: Oil Leak And Rough Idle - CEL On

My 2001 Santa Fe is having some major issues with rough idling, and there is a fairly significant oil leak. The check engine light is not on. In the past year it has had a new fuel pump, fuel filter, valve gasket covers, spark plugs, spark plug cables, and transmission.

Santa FE SM (2001-06) :: 2004 2.7L V6 GLS - Vibration At Highway Speed And Idle

I have a 2004 2.7L V6 GLS Hyundai Santa Fe AWD that I purchased about a year ago. The car has about 114,000 miles on it I believe. My problem is that I have an annoying vibration at idle and at highway speeds of 60-65 mph. The vibration decreases somewhat towards 70 mph. The vibration at idle is usually present, but sometimes vanishes for no apparent reason. The car is very smooth below 55 mph, but when around 60-65 mph becomes quite violent at times. The side view mirrors shake very badly and the vibration can become tiresome.

Originally the shop believed that the front axles were the culprit and replaced them – this mitigated some vibration felt through the steering wheel, but not much of the vibration throughout the cabin. The wheels have been balanced 3 times, alignment checked, and wheels do not seem to be bent/dented. (The tires were road force balanced)

In addition I have also had the following work done:

-2 oxygen sensors replaced (both post-catalytic converter)
- 2 Catalytic converters (replaced to pass emissions)
-Timing Belt Replaced
-Serpentine Belt Replaced
-Idler Pulley and Auto-Tensioner Replaced
-Ignition Coils Replaced
-Spark Plugs Replaced
-Transmission Fluid Change
-Oil Changes
-1 Tire Replaced (Sidewall Blew Out) (Michelin LTX M/S2 Tire)
-Air Filter Changed
-Crankshaft Position Sensor Replaced (It was Corroded Away)

Why the car is vibrating so that the mechanics can check it out. One idea I have could be the engine mounts – this would explain the vibration at idle (in park). I drive about 10 hours a week on the highway at the speeds that cause this vibration.

Santa FE SM (2001-06) :: Rough Idle - Oil Light Flickering

At idle, (600 RPMs, might need to bring it up?) the motor is Real rough, but doesn't stall out, just very "wobbly" Once the car is brought up to the 900-1000 RPM range everything flattens out, and at driving speeds it drives great! Pulled up to 90 mph on the high way, and passed a few cars on some back roads and everything ran great, until I hit idle.

It threw a code for the Cam Position Sensor after I tried to restart the car, and the person who work on this car before me had zip tied the connector into the sensor because he had broken it. Low and behold, you cant buy just the replacement part of the harness.

I tried to get the wires all plugged back in, and the CEL went away, but the idle was still pretty rough. Also, at idle, the oil light flickers just a bit.

Santa FE SM (2001-06) :: 2003 - Rough Idle When Using Brakes

2003 Sante Fe is suddenly having a problem at stop lights or anytime the car is stopped with brakes. It feels as if the car is going to stall - or back fire. Very evident since it pulls on the brake pedal - just had back brakes replaced.

Santa Fe (CM - 2007-12) :: 2006 - Fan Will Only Come On When At Max Speed

My 2006 (new shape) Santa Fe experiencing heater fan problems. Started off with it all working fine, except it wouldn't turn off the fan completely. Now the fan will only come on when at max speed. I've taken it to the Hyundai dealer and they recommended changing the heater control unit on the dashboard. I managed to find two second hand units but each time these didn't work - they lit up ok but no power to the fan was delivered.

Santa FE SM (2001-06) :: Rough Or Bumpy When Idle At A Traffic Light

I have a 2003 Hyundai Santa Fe. Within the last 2 months or so I have changed my timing belt, spark plugs, and all belts that needed to be changed. I notice that when I am idle at a traffic light, the car is a little rough or bumpy. Is this normal for its age, or should I be looking at something specific.

Santa FE SM (2001-06) :: 2004 - Rough Idle / Sputtered Down The Road

A few days ago, I started my wife's Santa Fe (106k miles) to warm it up and it had a rough idle. I gave it a test drive and the engine light came on and off a few times as it sputtered down the road. I retrieved the codes with my scan tool and it showed - P0300, P0304 and P0306. After some researching, I decided to change the coils, plugs and wires (under upper manifold) this coming weekend.

I have seen the web page instructions for doing this on a 2.7L [URL] .... but it has less stuff around the manifold compared to our Santa Fe. These instructions doesn't include coils was well since the plugs in front use just wires.

My question is.. Is there a set of instructions for the 3.5L for removing the manifold?.. From a less intense standpoint, maybe some of the hoses and cables can stay intact just to move the upper manifold or lift it to the side?... Also, Cyl 2, 4, 6 are the three sparks plugs in the front? 2004 Santa Fe 3.5l ....

Santa FE SM (2001-06) :: Car Has Hard Start, Rough Idle With Stalling

My coworker is giving me a clean 2001 Santa Fe with 151000 miles. It was running fine then all of the sudden it lost power but was able to stutter home. I went to check it out it started fine but idled a little rough. When I revved the engine it rose to about 2500rpm and stuttered then stalled. Kind of like it was rich and choking out. It then had difficulty restarting.

Santa FE SM (2001-06) :: Cold Start Rough Idle For 20 To 30 Seconds

I'm having this cold start issue with my 2001 SF, but it doesn't seem to be fuel related like as the car starts fine but after about literally 1-2seconds the RPMs drop below 1k and the car will stall if I don't put my foot on the accelerator and keep it around 1000-2000 RPMs. But if I happen to make the revs go too high and let them drop again it seems like it wants to stall even easier. After about 30 seconds it smoothens out and drives almost perfectly except for a slight lack of power than normal going uphill (A.T drops to 2nd gear, sometimes 1st depending on the incline). We have had the coolant temp sensor and the fuel pressure sensor replaced. Could it be the MAF? We did clean it one time but it didn't seem to work much at all. Recently out of curiosity, I disconnected the MAF sensor and started the car it being started for a few days. No issue with idling whatsoever!.. ??
