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.
View 2 RepliesI'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?

I have a 2003 Santa Fe 3.5l FWD 155k miles. Car has been incredibly trouble free until now. When the transmission up-shifts from 2nd to 3rd there is a hard jolt. All other up-shift and down-shift points work smooth. Occasionally will shift smooth just after I start the car or if I am accelerating hard. The rough shift happens whether I am in D or use the "manual" shift control. This coincidentally(?) started just about the time I had a battery die hard and an O2 sensor fail. Both have been replaced. Changed the AT fluid and no difference. No engine codes, but I think the AT codes don't show there? What might be going on? Any chance the battery failure had anything to do with this? Seems odd that battery, O2 sensor and transmission all start acting up at the same time.
View 5 RepliesIt'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....

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 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.
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?
View 7 RepliesI 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.
View 12 RepliesHaving a very pronounced hesitation/slip between 2nd and 3rd gear shifts. It happens in both "D" and "S" modes. I've had the tranny flashes and they fixed the throttle hesitation and the general harsh shifting. Still have a slip when going from 2nd to 3rd.
View 5 RepliesWell - took my car into the shop today for the death lag, harsh shifting, and acceleration during braking. I've read much on this site about tranny flash and ECU flash, and was hopeful there was something available for my 2004 V8 (I just purchased it in late October, but was unsure what TSBs and campaigns had been applied before I bought it)...
In the end, dealer was able to replicate/experience the harshness problem, but was unable to come to a confident solution. My 86xxx VIN V8 Treg was not due/eligible for the much discussed tranny flash (my engine type was right, but the tranny flash was not listed for my car). In fact there were no recalls or campaigns due for my car, and there were no faults on the computer.
The dealer stated the cause as "Harsh shifting patterns". and fixed via "Reset TPS and TRANS". Essentially, I was told, let the adaptive driving feature relearn, and hopefully replace the previous harsh shifting pattern. My ride home from dealer was short, so not sure if there was any effect - but I'm not confident.

Our intrepid 3.5L with 135000 miles has been acting up a bit. Its had a couple hard shifts over the last few days/week that almost seemed like an engine hesitation, and this morning when slowing down from highway speed into a small town, it abruptly shifted down to 2nd and stayed there like its in "limp mode" ??.
Pulled over and checked fluid. Level looked good and smelled ok but has a brown tinge to the pink fluid.
Started to go again and it still wouldn't shift. Pulled over and shut car off. Checked codes P700 and P138.
Started car up and it shifted fine for the next 28 miles. Shut car off and parked it.
I just bought a used 2004 Elantra that has 97,000 miles on it. When I took the vehicle out for a test drive it was smooth and quite. That was on Monday its now Saturday less than 300 miles later and the check engine light came on and it is having serious hesitation issues?! I am going to take it back where I purchased it from on Monday when they open but in the meantime I would like to know if its could be something simple?
View 14 RepliesThere is only one thing I don't like about our new SF. The transmission shifts from 4th to 5th gear at approximately 60 km/hr (36 mph +/-) and the rpm's drop to 1500 rpm. Now, when I want to speed up a tad (which is a frequent occurrence when driving around town), there is a pronounced hesitation before it drops back into 4th gear and accelerates.
In 5th gear at 1500 revs, I find that the engine is 'lugging' a bit. Yesterday, I started to compensate for this by changing to manual shifting as soon as the trannie shifted into 4th gear and leaving it there when I was traveling in that 60 kph speed area. For me, this is MUCH better and I quite like doing some of the shifting any way since I spent so many years driving manual transmission equipped cars.
How have others found the car to be when driving around town? Other than that, I really enjoy this car. Easily the most comfortable seats of any car I've ever owned --- their design provides terrific lumbar support and the new cloth material has a great 'feel' to it.
We have a 2010 Santa Fe AWD LTD with about 140, 000km on it. It recently came back from front suspension work. The suspension is fine now, but we notice harder shifts in the transmission. Also, there seems to be a vibration just before shifting gears and when under load (like going up hill) seems to slip (like on ice) about once every second until the shift is made. Once the shift is made it drive smoothly until put under pressure again. Even stepping down a bit on the accelerator will cause this slipping feeling (or maybe its loss of power).
View 4 RepliesJust experienced something new in my less than a week old 2.0T. This morning was the coldest day since buying it (-15c). I had the block heater plugged in and it started up well. Let the engine run for my usual 30-40 seconds before putting it into gear. Reversed well, but was a bit slow shifting after putting it into 1st.
For the first 5 minutes or so of the drive, the shift were pretty rough. Mostly the shift between 1st and 2nd gear. Things got better after that and were fine for the rest of my trip and also an hour later when I came home.
Is this just a case of a very cold transmission and fluid, or is it something else? I've never owned a car that had such rough shifting in cold weather. Sluggish shifts yes, but not violent like these were.
My 2009 Santa-Fe AWD Limited is sick! Starting from a stop, the vehicle has abrupt shifts with the transmission slipping (RPM revving). Seems worse when cold. Checked the fluids, and found ATF fluid in the engine oil and engine oil in the ATF fluid. Quick internet check suggest a leaky vacuum modulator valve. (There is no way the fluids went in the wrong holes, the vehicle only has 69k kilometers on it, so it still has original ATF fluid, and I recently changed the engine oil myself.) So, do you think this is the correct diagnosis? How hard is it to change the modulator, and where is it located?
View 3 RepliesI just bought a 2010 Santa Fe with 52,000 miles. The car looks great and runs fine once warmed up. Problem came after I got it home. I have found that it shifts rough when first started for about 5 miles. After that it runs great. From a quick search I have found 2 TSB's that may apply, 10-AT-006 and 11-AT-011-2.
View 36 RepliesI 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.
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).
View 17 RepliesPurchased 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.
