Hyundai - Santafe :: 2013 - Sudden Power Loss When Accelerating From A Slow Speed Coast
Occasionally, randomly, and unpredictably when accelerating from a slow speed coast I get no power response when I press down on the accelerator. It's as if the engine has stalled, but it has not. When the accelerator is held down for a few seconds (maybe 3 to 7) power comes back with a rush. Examples:
1. Making a U turn from a left turn late. Accelerate slowly forward, take foot off gas as the turn is initiated, press down on gas to accelerate out of the turn and get no immediate power response.
2. Making a left turn into a suicide lane. Accelerate to cross 2 traffic lanes, let off gas and coast slowly forward in the suicide lane while waiting for oncoming traffic to clear, traffic clears, press down on gas and get to response. Continue to press slowly down--no response. Hold the accelerator half or 3/4 down, power surges back after a few seconds.
3. Rolling slowly down a long left turn lane with foot off gas timing oncoming traffic, traffic clears, press down on gas to initiate the turn, no response. Let up on gas and press down again, no response, let up an press down again and car reacts normally.
Occurrences of this problem have been very random. I have spent a good deal of time in vacant parking lots trying to cause the problem to occur without any luck even though I know well the conditions under which it happens. I have left the car with the dealer but, of course, they can't observe the problem either. I have driven nearly 1000 miles without an incident and then had 2 occurrences within 4 miles of each other. I have about 5000 miles on the car and have logged 17 incidents.
Loosing power in traffic is, of course, dangerous. I was about to initiate action under California's Lemon Law when I went to England for 3 weeks in Sept. I rented an Audi A1 and to my surprise I experienced a very similar problem, but it happened much more often. An example would be entering a roundabout, letting up on the accelerator while looking at directional signs, reapplying accelerator pressure and getting no response. Unlike the Hyundai I didn't seem to lose all power, but couldn't get any acceleration. The Hyundai engine is the 4 cylinder turbo and has an electronic throttle. I don't know what the Audi had by way of mechanics. I'm at a complete loss; is there something I don't understand about electronic throttles? I don't have a clue about the source of this problem, but I know I need to get it resolved before I get rear ended.
Hyundai - Santafe :: 2004 - Won't Start After Fueling
My 2004 Santa Fe doesn't want to start after fueling. It doesn't matter whether it was just a few dollars worth or a full fill up. After pumping the gas and recapping securely, I have to press and hold the Accelerator to get it to catch. I had the purge control valve replaced a few months ago. And my car started mourn normally for a while. However I'm back to having to push progressively harder on the gas pedal to get it to start after gassing up.

Our 2004 Santa Fe 6 cylinder ( front wheel drive) was being backed up when a Clunk was heard, and then the Battery and the Brake lights came on. My wife called the dealership and they say not to drive it, but to bring it to them. What could the issue be?
View 6 RepliesHyundai - Transmissions - Santafe :: 2004 - Hard / Lurching Shift Into 3rd Gear
For the past 3 months, upon shifting from 2nd to 3rd gear, the car lurches forward in a hard shift. Sometimes, it is nothing more than a benign "clunk", and other times it is violent, as if hitting a wall. This does not happen every time it shifts and even under identical acceleration, the results vary from none to violent. The number of violent shifts vs. small jolts has increased over time, and all other transmission functions and shifts are fine/normal. After much time researching the inter-blogs, I have come to no consensus on what is causing this or how to fix it.
Some say it is the adaptive shifting program and it just needs updating and others say it's the tranny and a rebuilt tranny replacement is the only thing that eventually fixed this problem (though one posting on the Hyundai forum is of the same exact problem, but the solution is worrisome -- contact negative battery terminal to positive, let sit for 10 min, reconnect, then drive at 1/3 throttle, shifting through all gears a dozen times. Poster says this resets adaptive shifting program and worked for him).
Finally, today, I took it in for a diagnostic with a local transmission specialist, and they could only replicate the hard shift once, but when that happened, he said the car went into limp mode and read two codes: P1193 and P2127. The car has never gone into limp mode (P1193) nor shown an signs of suppressed RPMs associated with this mode. Also, he seemed to focus his attention on the low voltage to the pedal position sensor (P2127) as being the major issue that is causing the hard shift. I also called a past dealer that worked on a similar issue with the car when I bought it used 4 years ago and they recommended updating the adaptive shifting program as they did last time; though I don't recall if the shifting issue was the exact same problem I am having now. So, a few things:
Does this sound like a computer issue or a tranny issue? Could the pedal position sensor having low voltage cause a shifting problem like this? Any merit to the connecting the battery terminals idea? Should I be wary of the mechanic that did the diagnostic today?
Hyundai - Santafe :: 2004 - Intermittent Metallic Buzzing Evolved Into Constant Whirring / Grinding Noise
For about a year and a half I have had an "undiagnosable" noise that started as an intermittent metallic buzzing and has evolved into a constant whirring/grinding noise. The tempo of the noise increases when accelerating; occurs at all speeds and at idle. People say they know when I am approaching they can hear my car from about two blocks away.
My regular 20 year mechanic checked transmission, replaced timing belt (at 65K; now have about 74K); all idler pulleys; checked alternator; He thinks is is the AC drive pulley on the compressor; Hyundai dealership did not know what it is; laymen have suggested is is a power steering pump, reservoir issue. Power steering fluid level is fine. Otherwise, the performance of the car is fine.
Engine is 3.5L V6; 2004, about 74+K
Hyundai - Santafe :: Pulls To The Right
My car pulling to right significantly at all speed. Alignment checked mechanic says its normar to have car goes to right. I have similar car for 10 years 140,000 miles never have this kind of pull with many tires changed and rotation of all kind. While mechanic was doing wheel alighment white brown greese / liquid came out from steering rack on right side. Mechanics says its just oil seal from steering rack oil seal. Car was pulling to right before this rack leak as well. Mechanic says need special bolts for this car to adjust some camber on this car and can make this better.

View 2 RepliesHyundai - Santafe :: Hesitation On Acceleration And Rpm Changes While Cruising
I have a 04 santa fe 2.4L 4cyl. I recently did an engine swap, old motor threw a connecting rod. I put my intake, exhaust manifold and head on it. Timed it. All new gaskets. Turn the key and it fires right up and runs great. But when you accelerate it sounds loud (almost diesel like) and doesn't shift at the right time, also while trying to cruise it will drop about 300 rpms and then come back up, then back down and up every 3 to 5 seconds. The transmission was fine when the old motor came out. The head/intake were fine also. All the vacuum lines are connected, cant hear a vacuum leak anywhere. But it keeps throwing a throttle body sensor code and it wasn't broken when the old motor went, i even swapped another used one on it and it still throws that code. I am thinking it has to be intake related.

I have a 2003 hyundai Santa Fe that has had a problem for a few years that I can not figure out, nor can the hyundai dealership. (Though they seem to only want to hook it up to a computer, which tells them that nothing is wrong.) After filling up the car with gas, the car will turn over, but will stall immediately. You can press on the gas and it will stay going, but once you take your foot off the gas it stalls. It act like when you used to flood the corroborator. It takes about 4 times of turning over the car and stalling before it runs normally.
It is a GLS 4-cyl automatic AWD.
Hyundai - Santafe :: 1995 Try To Turn Over But Won't Start
My (mom's) Hundai will not start. It tries to turn over but never makes it. We don't smell gas, not flooded, might be the fuel pump. The code sensor device will not give a code to indicate a specific problem.
In the past, the car will give a static shock every time you get out and push door closed. Very difficult to start and gas must be pumped to start after gassing up. Also, a bell (ding sound) rings at random even if the car is driving. What to look at next?
Hyundai - Santafe :: 2005 Won't Start After Filling With Gas?
I have a 2005 Hyundai Santa Fe, about 128,000 miles on it. For the past 5 months or so, the engine simply won't start after filling with gas - and only after filling with gas. I've tried filling partially from near-empty, as well as filling full from halfway or more full...it consistently won't start up after filling with gas.
After turning the ignition, the engine will turn over, but quickly quits. Lately it's had more trouble turning over at all. To get the car moving, I need to actually feed it gas with the pedal, and "simulate" idle. Even after a couple of minutes, if I let off the pedal it dies right away....as if gas just isn't getting to the engine on its own.
In order to get the car moving, I just have to keep feeding it a bit of gas while shifting to drive (and stepping on the brake), then I give more gas and let the brake go almost as if it's manual-transmission....off it goes.
Oddest thing: as soon as that happens; as soon as the car moves forward (even just to get out of the gas station), everything's back to normal. The car idles healthily at the next stop, as if nothing happened.
No check-engine light, no diagnostic codes come up with a scan. Same results on warm or cold days. Most recent maintenance on it was new spark plugs almost a year ago (doesn't seem related).
Of course, the only time it DID fire up normally after filling with gas was when I had the mechanic with me in the car!
Hyundai - Santafe :: RPMs Going Low And Stalling Out While Driving
I have a 2004 Hyundai Santa Fe with about 83,000 miles. Lately it has been having issue with the rpm's going low and stalling out while I'm driving. I've taken it to a mechanic and it has not been resolved. He said it does not need a tune up and it's nothing with my fuel. I've also heard it could be a crank shaft censor but he says no. The check engine light has come on sometimes, very quickly but then goes off.. He ran the code but nothing came up. So then what's causing my car to do this?? While the car is running and I'm in park, the rpm's will go from 2 to almost 0 then back up again. While I'm driving down the road it does the same thing and sometimes it completely stalls out while I'm going about 40mph. So incredibly scary. What this could be so I can take it back and get it fixed!!!! I'm so scared to drive it but I have to get to work.

the passenger seat in our 2015 hyundai santa fe sport is not power but the seat can manually adjust forward and backward and the back rest can be moved backward and forward. The seat cannot be moved up and down. It is way too low and it feels like sitting in a "pit". The dealer said to sit on a pillow but when I sit on a pillow the air bag light will not go off (so the passenger air bag is not activated). If I sit on a book, the air bag light does go off but who wants to sit on a hard book all the time. The air bag warning light does go off when I sit on the seat itself.

View 5 RepliesSanta FE SM (2001-06) :: 2004 Hyundai 2.7L - Loss Of Throttle At Random Times
I've been having trouble diagnosing a loss of throttle at seemingly random times. Sometimes while driving, especially after driving for more than 20 minutes or so, I will experience a hesitation while on the gas pedal as if I have taken my foot off the gas. It makes it impossible to drive until I pull over and unplug my TPS and then I can drive fine in manual mode. Then the next day I can plug my TPS back in, drive around fine for a bit before the hesitation happens again and then I have to unplug the TPS again and drive in manual mode. It doesn't make sense to me why it takes a bit for this hesitation to begin and why unplugging the TPS and driving in manual mode seems to fix the problem.
I've recently replaced my crankshaft position sensor, idle air control valve, purge control valve solenoid and TPS. When I recently placed the TPS, the hesitation problem and another problem I've been having recently, a high idle in park, seemed to be fixed, but then the hesitation problem popped up again. When I unplug the TPS, the hesitation disappears and I can drive fine but the high idle in park problem is back! I'm suspecting some sort of wiring problem to the TPS. I just went on a 100 mile camping trip in manual mode no problem, but I can't be driving around forever with no TPS.

I used some mass airflow sensor cleaner yesterday. My Hyundai santafe check engine light came on but it was running fine. Tried to drive it this morning and it was missing bad and kept shutting off. It would cut back on, once in drive and move a few yards it shut right back off. I cleaned the sensor BC my truck kept idling up high and shutting of when coming to a complete stop. It seem like it was flooding itself, kept smelling fuel when I would try to start back up. Knew it had to be fuel regulator or air flow sensor. So I decided to clean air flow sensor before buying parts. Now after cleaning truck is worst but at least it will start right up. Unlike at first when I would have to wait 15 mins when it shut off.
