Santa FE SM (2001-06) :: Power Loss - Vibration / Missing When Idle
Jun 13, 2013
My father owns a 2003 Santa Fe GLS with the 2WD 2.7L V6 engine.
Recently it has been having lots of power loss issues. It vibrates/misses when idling, if you put your foot down on the gas pedal, whether under load or not, it sometimes stalls or just sits there. We took it to Hyundai, and they had no error codes. They charged us $150 to tell us nothing is wrong with it, when clearly something is. The car has become downright dangerous to drive because it cannot make it up hills without stalling/losing power.
The most recent thing we had done to it was the wires/spark plugs changed, which I think was at 65k on the odometer?

My 02 excursion is missing at idle and jars the whole truck around going approx 50mph feels like good amount of power loss but still pushing 30psi boost, just got autoenginuity all injectors buzz fine on the test, contribution test show balance fault in cylinders 1&8, should I look for o-rings to be bad, uvch, cups cracked or what ----- turbo fine, hpop great condition, new IPR, new fuel pump and hutch mod, about. 250k miles on truck nothing else major showed up on ae.

I will occasionally get a misfire after a rain storm, lasts about ten minutes then goes away. there is also a slight miss (no CEL) at idle, that occurs all the time. I'm thinking spark plug wires.... the plugs were done last year, but nothing else. to my knowledge the wires and coil packs are all original. i'm at about 114K on a 2004 santa fe 3.5l.
Also, does the computer store misfire codes? I know I got them in the past and i checked it at the time, but didn't write down what cylinder it was. think it'll still be in memory?
Think it's ok to change just the wires and not the coil packs? kind of on a budget...

2001 Excursion 7.3 started missing the other night. Great loss of power, but made it home. Rough idle, "clacky". Next morning, did the following in order: 1) Pulled the fuel filter inspected, 2) removed all fuel from the bowl 3) replaced bowl fuel with Seafoam 4) installed new filter (my typical procedure). Without starting, I then 5) removed HPOP oil from reservoir and 6) filled with fresh oil using exact amount removed as a gauge for what to replace.
Started, idle smooth for a time. Increased rpm by depressing accelerator. Began running rougher and rougher accompanied by white smoke. Finally quit and would not restart. Cranking easily, tachometer showing RPM during crank. Suspected no fuel getting to fuel bowl. 7) Drained fuel bowl using valve on back of bowl. 8) Turned ignition to "on" to get fuel pump to run 9) removed new filter, no fuel in bowl 10) With fuel filter out of the bowl, removed fuel filter and quickly cycled the ignition to "on" and back off -- no fuel entered the bowl. 11) Removed leads from fuel pump. 12) Checked voltage across leads as ignition cycled to "on": 6.5 volts. 13) Checked fuel pump fuse (20A Maxi fuse in location 112 -- BLOWN!) 14) Replaced fuse, performed voltage test: 11.55 volts 15) Checked battery voltage: 12.44Volts.
So, with all that, how in the world does the fuel pump get 6.5 volts with the fuse blown? I looked closely at the fuse and there was no slag or connection in the element. Today I have pulled the 9-pin and 42-pin connections on the valve covers as well as the connectors to the glow plug relay module (used on Ex's) to inspect wires and connections. All looked fine. I plan to us some LP5 electro contact cleaner to clean all the connections and put some electrical grease on the connections, but the big question is where did that 6.5V come from with the fuse blown. I plan to pull the fuse and do the same test to see if the 6.5V is still there.

I have a 00 Accent with 132k miles, I replaced the motor a year ago with a correct 2000 Hyundai 1.5 with 50k miles. I replaced everything that I could at the time, timing belt , starter, water pump, and clutch. It has been running fantastic getting 40 miles per gallon with zero problems , However in the last week I have noticed a rough idle that seems to miss with a vibration that it didn't have before. I have a noticeable loss of power and torque. My miles per gallon has also dropped to about 25 mpg. My check engine light is not on. I will check the plugs and change the air filter today but I would like to know what else could be causing the problem as I am not really sure what to check.

My problem is my 2001 Santa Fe petrol 2.7 L its done over 300,000 km one day it sounded like a click when driving, then when I started it cold in the morning it was missing [not running right] and had no power until it warmed up the spark leads are not that old anyway I put new spark plugs in it it seem to run a lot better but seems to be down on power on hills I think coils are ok? the motor not smokey but burn little bit of oil.

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.

When I start the engine it works fine while the motor is cold (idle normal all smooth). When the engine the temperature reach normal operating range the car loose power and idle drops to 350-500 rpm and if i am driving I can not go over 40mi/h. I drive a 2008 Sta Fe now with 96000 KM (~~60000 miles). A month ago the engine start shaking severely and knocking noise (like some spark plugs where not working), from this to now:
Changed all sparks plugs
Changed all ignition coils
Now this situation looks more related to temperature of the engine.

I recently bought a 2004 Hyundai santa fe 2.4l with 94k miles. when sitting at a idle it has a slight vibration in the cabin, feels like a slightly rough idle, when you drive the vibration is gone. I also had it throw misfire codes for cyl 2 and 4. I put in new plugs and changed the wires, coils are on the way. When the car is in drive and I put the parking brake on and walk up to the motor it sounds like it has a exhaust manifold leak, but I only hear it when in drive. I guess my question is, could this exhaust leak be causing the rough idle or will this be fixed once the new coils are on?

Dad has a 01 one ton with the 7.3 and isn't real tech savvy so I'm posting for him. He is the original owner and has been complaining recently about the lack of power. Particularly the upper end. He is having to downshift way more often and where he used to not have to. And we've both noticed a very noticeable shake at idle. Not a vibration but a true shake. He changes the oil every 5000 on the dot and I've gone and changed the air and fuel filter and ran hose and see foam and royal purple injector cleaner through it with no results. Truck is all stock with 225000 on it.

2003 Santa Fe - Loss of power while driving on highway. Dropped from 60 to 15 MPH in matter of seconds. Feels like a couple of cylinders (3.5 liter) are not working.

I have a Santa fe 2002 crd 2.0 4x4 and recently had a lot of black smoke and a loss of power when driving, it starts fine but when revving it blows black smoke from exhaust and has no power to pull away, been told its possible turbo problem or fuel problem.

Today I took my AWD 2.7 Santa Fe out. All seemed fine until I made a turn... I noticed I was loosing power and came to a stop, despite pressing the gas pedal fully. The car then started to vibrate extremely hard and all of the dash lights came on. The car stalled completely. I tried to start the car again, but it took a few tries. The car shook severely in park, but when put in drive immediately became much worse and then completely stalled. I did this many times trying to get out of the street. I finally got it to work good enough to get off the road - I did however notice that it would not shift out of 1st gear. It had very high rpms, but refused to shift.
I am guessing this is the crankshaft position sensor? Could this be a MAF problem? I believe I read on this forum about high humidity making Santa Fes go crazy - it has been over 95% today, and raining. I managed to get the car down the road to a shop we trust. They are going to try and read codes later.

Bought my Santa Fe GLS less than 2 months ago and ran fine. Last week, went to store no problems and then went out 5 minutes later, put it in reverse and it stalled. I go to the store, and it lacks MAJOR power.
Now, if I leave it alone for a while it will normally start right up. While idling, everything seems fine. Then my "ghost" takes over the vehicle making it less responsive to the gas pedal. Also, at 3000 rpm, it sounds like its skipping a cylinder. When reading the gauge, it skips between 3000rpm to abut 2800 rpm.

I own a 02 fwd v6 Santa Fe that just lost power on the interstate. It will go about 20 miles an hour and basically does not change gear unless it is in manual mode. I was able to drive it to a local repair shop but they are having trouble figuring out what is wrong with it.
First, they told me the plugs and wires were bad, changed those and still no power. Next, they told me it was the fuel pump, change that and still no power. Next, they said it was the catalytic converters but the said they unhooked them to test the theory and it still had not powered. They said it may need back pressure from the cats so that may not work. They want me to buy them but they are very expensive especially on a guess. Next, they told me if that does not fix it is must be the transmission. Will the cats off keep it from running due to back pressure? Does it sound like a transmission issue or could it be something else?

Initially I used to get cutting out of the engine randomly whilst driving which everyone believes is linked to an ECU issue i believe...I added some reddex fuel cleaner and that seemed to clear the problem up for myself which is a diesel 2.2 ...
However I was beginning to have starting issues where i would need to pump the gas to get the car started...I changed the battery and the glow plugs and yet i was still having issues. I had the air intake and filter looked a diagnostic test run both showing no issues and then one day I was driving and suddenly i got a huge loss of power and black smoke out of the exhaust....Seriously i had no grunt and i was a hazard to cars behind me....!!!! It was weird how first thing in the morning it seemed fine but later in the day i was getting this problem over and over again and eventually the car wouldnt start without a jump from another vehicle..
Any how i took it to various garages but in the end i took it to Rockar Hyundai at Dartford (i cannot recommend enough) but simply all they did was look at the fuel filter and saw that one of the injectors were faulty...After changing this the problem still occurred but again only when the car was warm...They then looked at the pipes leading to the injector that was faulty and then found that there was a crack/split in it and obviously when cold it was sealed but when warm was opening and i believe letting in air.... Anyhow they have changed that and the car feels great and no issues...

2004 2.4L Hyundai Santa Fe here, died whilst travelling, lost all power and then wouldn't start. Sounds like its trying to turn over.
The fuel cut off seems to have been activated as it clicked when I pushed it but the car still wont start.
I do not have any engine management lights but when connecting the code reader I got P0320, however the code was stored but not present... and still the car will not start. I cleared the code and the code didn't re appear but the car will still not start.
As the code isn't immediately present does this mean the sensor is at fault or do I have other problems?

I just recently bought an 06 Santa Fe with a 2.7l v6. It was a rebuild. It had been hit in the left wheel. The lot put a new fender, suspension parts, axle, etc. It only has 25k actual miles.
We took it on a 100 mile trip today. I noticed if I am going up hill and it has to downshift, it feels like it looses power. The car continues to slow... Like the tranny is slipping. I stopped at Walmart and found the tranny fluid wouldn't even register on the dipstick. I bought Valvoline max life tranny fluid that matches the sp3 specs in the manual. I had to add almost 3 quarts before it was full. I think they may have forgot to add fluid back to replace what leaked out after they replaced the axle It didn't seem to work though when I continued to drive. After I stopped and let it cool about 30 minutes, it did seem a little better.
I guess my question is should I replace the tranny fluid? If so, what should I replace it with? Is there anything else what could be causing this now?

On my '03 Santa Fe 2.7, this has happened twice, with 500 or so uneventful miles in between. At highway speed, it just all of a sudden loses power and will only go about 50 mph with accelerator to the floor. When you stop & put in neutral, it only revs to about 3000 rpm, with pedal to the floor -yet idles fine. Then when you shut it down, wait a few minutes & start it back up, it's fine. Is this a fuel problem or what?

We have a 2002 Sante Fe with v6 and 270,000 km on it. Just had extreme loss of power and jerky acceleration from a stop. This has happened a few times in the past year and each time with a 1/4 tank of fuel? We pulled into a gas station, filled it up and away we go like nothing was wrong?

When I bought the car a few weeks ago, there was a p0507 code for a high idle in park, about 1300 RPM, but sometimes shooting up to 3000 when I shifted into park and then dying down. The code goes on and off intermittently. Not that big of a deal at first. Then I started noticing that if I revved it in park it would take forever to die down to 1300, and sometimes would fluctuate around 2000. I also noticed hesitation while accelerating around 1500 RPM and the transmission hunting for gears while accelerating, as well. I noticed my throttle cable was very slack so I tightened that, and bought myself a throttle position sensor, thinking that might be the problem, but didn't install it yet.
I was driving on the freeway yesterday in cruise control and then I started losing power while my foot was on the gas. With my foot on the gas, the throttle would cut out every second. I was basically one second of throttle, one second of no throttle, all the way down the highway. Almost impossible to drive. This continued even after I turned cruise control off. I limped my way to Home Depot and installed my TPS in the parking lot, and drove most of the way home with no issues, although I still noticed a slight hesitation while accelerating. Alas, I tested cruise control again and then the throttle on/off problem started again, then I could barely drive the thing, even after cruise control was off again. I'll be returning the new TPS to Autozone today, since apparently that's not the problem. What's my next move?
