Santa FE SM (2001-06) :: Brief Hesitation When Driving
Jan 14, 2014
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.

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?

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....

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.

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.

I have an '02 Santa Fe GLS V6 2WD. I am having a strange problem and do not know what it could be. When car is cold, it starts up and runs with no problems. After about 15-20 mins, there is a slight hesitation or studder. RPM's drop slightly and shutters. When i accel, engine studders, then runs fine. This only happens when at idle in drive. At highway speeds there is no problem. What can this be?

I bought a 2002 santa fe last week. it was a non runner. the previous owner said he took it to the garage for a crank oil seal leak. when he went to collect the car they had removed the head saying oil was leaking from the gasket. he towed it away and i bought it. i have refitted the head. the engine runs smooth at idle. when i first start up in the morning there is a loud rattle for a second or so. it sounds like a diesel starting up. when i am driving it hesitates and seems to lose power. also at a certain position on the accelerator pedal this rattle is there. it goes away when i accelerate more.

In january I took my 2001 Toyota corolla to the mechanic (that had replaced the engine 5 years ago) because it was using oil and gas mileage was very poor. He gave the car and tune up and right afterward I noticed the car hesitated for just a second within the first mile of driving. After the hesitation it had full power.
Then the check engine light came on with a code for O2 sensor; I had that part replaced about 2-3 years ago. So that was replaced. The next day I was driving on the highway when I heard a pop and lights came on everywhere. The car ran, but when I stopped, it was smoking and wouldn't start. AAA towed it and said the water pump broke and took the serpentine belt with it, and I had it repaired there.
Car continued to to the "hesitation" thing, but I learned to live with it, until 4 weeks later it lost power and wouldn't go more than 5 miles an hour. Very dangerous! Also the check engine light came on - O2 sensor again. The original mechanic towed it back to his shop, has had it over a month. Say sometimes it runs fine and sometimes it really hesitates. My son took the plugs out and said they didn't look new and replaced them with best quality new plugs (mechanic said the plugs looked worn due to problems reported).
He's been a mechanic his whole career and still can't find out the problem. He checked the MAF and said it's fine. I can't afford to put more money into it, but it's worth nothing but junk value now after putting over $1000 into it. I didn't have these issues before I took it to him in January. He has a good reputation, but I don't know what gives.
Is this all a coincidence that it happened at once? What could have happened?

What could it be? Replace front brakes. Then they said it was front axels, replaced them. Making same noise... grinding and feels like you are hitting brakes when you are not. Sounds like metal on metal. What else can it be? 01 sante fe 180,000 miles v6 awd. It was doing it in reverse but after all of this now just in drive at slow speeds.

3.5L v6 173k. Engine shut down twice while driving. Started right up each time. From what I have seen in the forum it could be the Crankshaft Position Sensor. If it is the CPS, should I have the timing belt done at the same time?

So I go on vacation, and as we're driving down, the CEL comes on with p1166 pd1166. Get home the code still pops up. A month later small oil leak is detected. Clean the throttle body intake, fuel and exhaust systems. Oil leak gets worse, turns out the crank shaft seal has failed. Shop cleans out the oil, and replaces the timing belt. Clears the code and the CEL stays off for 5 days. I clear the code and Its good for days. Get it up over 50 and the CEL pops on. So today go for a trip mostly highway driving. I go over 125 miles with out the CEL coming on. Check it and the reader reports pd1166. Clear it. Driving back 4 miles and the CEL comes on. 2 codes p1166 and pd1166.
What are the time parameters for logging a pd1166 and the p1166. No engine issues, no performance issues. Gas mileage is 17-19mpg.

Driving down the road, no warning lights on, everything working fine, no stalling or any indication of a problem, car just shuts off. I think hmmm, put it in neutral and try to start, nothing, notta, zip ... engine not even attempting to turn over. Removed the battery took it to store had it checked twice shows to be good 100%.

My girlfriend has a 2005 Sante Fe 2.7L v6 AWD. Lately I've been noticing it more and more but when the car is driven for a good amount of time we hear a noise. I'd say maybe an hour or so (I've never measured it though) the car makes a whining noise when trying to turn the wheel or even accelerating. I feel some resistance in the wheel when it happens too but majority of the noise comes from turning the wheel. Also when this happens the car seems to want to pull to the right, i can feel the wheel starting to pull. If I let the car rest and cool down for like 20 minutes or so it will go away but then slowly come back. From what Ive been reading I think I can narrow this down to a power steering fluid issue, either its low, leaking or the screen in the bottle is clogged. I don't see any leaks, nothing pouring out the bottom of the car either.

I have a 2005 2.0 litre petrol Santa Fe. I recently had it serviced and after this I started to have problems with it suddenly cutting out or stalling momentarily while driving. This happens randomly, sometimes at slow and other times at high speeds, often when accelerating but a couple of times in cruise. It only lasts a second or two and picks up immediately but can sometimes happen a few times in succession. It never happened before the service. The orange check light with the exhaust icon (Malfunction indicator Light?) comes on sometimes but I haven't noticed it all the time. This problem is getting worse, more frequent. I pushed the car a bit today in 4th gear up to about 3500 rpm and it happened quite badly, a few jerks in quick succession with the light coming on then back to normal for the rest of the trip.
I brought it back to the garage who did the service (not a main dealer, nor my usual mechanic) and they ran full diagnostics on it a couple of times. Nothing showed up, no error codes and nothing logged on the car's computer. They tested the emissions and found them to be perfect. They didn't change the fuel filter because it seems to be built into the petrol pump but did put something in the system that is supposed to clear out any deposits or whatever. Not sure what it's called but some sort of fuel additive. That was why I drove it hard today. They suggested doing that to try and clear out the system. Doesn't seem to have worked.
The bottom line is they don't know what's causing this so I'll have to take it to my own mechanic or else the main dealer. I'm wondering what could be the problem. From searching the forum it looks like the symptoms could be consistent with a failing CPS, an oxygen or throttle position sensor or a faulty ignition relay. I also think it could be to do with a clogged fuel filter, dirty petrol or perhaps water in the fuel tank; we've had tons of rain lately and the car is kept outside! Given it started happening after the service I wonder if they could have fitted something wrongly, used a faulty part, maybe a plug, or left something loose/disconnected. They have however gone through it thoroughly to try and find the fault so I imagine they would have turned up something like that.

My daughter was driving our 3.5L Santa Fe on the highway when it decelerated. Stepping on gas and no acceleration. She said she got a CEL and oil light. She was able to pull over to the side of highway and turned ignition off and on and she was able to drive off the highway and called me. She was about 120 miles from home. She said the cel light and check oil light were now off and I had here check the oil and it was at full.
I had her drive in the right hand lane without going over 60 and she made it home no problem. I took it out for a drive and no issues. Do you think this is a crankshaft position sensor problem?
mileage is 170k - timing belt was replaced at 130k.

I drive a 2005 2.00 diesel Santa Fe which has developed problem when driving. The engine stops suddenly with no reason no Management info light appears i have the car checked and there are no fault codes present. Some time the burglar alarm lights comes on after the car stops it can take up to 15 mins to restart. This fault can happen 3 times a day and happens more often when driving at low speeds.

2001 2.4 L AWD Manual Transmission.
Live data readings from vehicle continuously indicates "open loop- driving" for the Fuel System Status (Fuel System 1) . During idle and on open high way driving as 120 km for 10 minutes. I use an ELM327 diagnostic device with ScanMaster-EL 2.2 software.
After establishing this initially I disconnected the battery to do a complete ECU reset. I do not get error codes.
O2 Sensor1 Bank1 constantly reported as 1.275 V and sensor 2 as 0.02 V. I believe however the constant readings are as as a result of being in open loop.
No error codes reported.
The software report OBD1 ability on the diagnostic link.
During driving I got the following readings:
Fuel System 1: open loop-driving
Fuel System 2: not supported.
Calculated load: 6.27 to 83.14, avg 40.6
Fuel trims: 0
RPM: 1008 to 3988, avg 2407
Speed (km/h): 0 to 122, avg 77.66.
Timing Advance #1 degrees: 7 to 44 degrees, avg 22.42
Intake Air Temp (degrees C). 19 to 24
Air Flow Rate - (g/s): 3.18 to 69.27, avg 25.46
The software reports that the O2 Sensor bank 2 is not supported. I am not certain whether I should trust the software. In South Africa cats are not mandatory, hence is it possible explanation.
2) Is it possible to send a command on OBD to force closed loop?

Looking for a picture/location etc of where the crank position sensor is in the engine compartment? It seems to be a common issue where the engine stalls during driving and you pull over and are able to restart the vehicle and go on about your business.
My 02 has over 160k in miles and so am believing this part is going out according to what I've read here. My problem before was somehow the 2wire plug to the alternator worked it's way off and got that taken care of and so now while my wife is driving, it'll occasionally stall. Did a load test on the battery and it's good. Didn't check the charging system but not sure it needs to be tested.
By the way, have ran the diagnostics with the actron pocket obdII and no error codes came up and all looked good scrolling through everything.

My Santa Fe 2004 V6 2.7L 97K recently downshifts and revs up while I'm driving. It happened about a week ago once or twice. I thought I was stepping on the gas too aggressively. But last 2-3 days it came back and more frequently to a point that I'm afraid to take it to the highway.
I checked the transmission oil, it looks pink and full. What problem am I potentially looking at? Would it be cheap to fix? Do Hyundai dealers cover it under the 10-year/100K mile warranty thing?
