Santa FE SM (2001-06) :: Vibrating / Pulsating After Cold Start
Apr 16, 2012
Long time 2004 Santa Fe owner here (LX 3.5 liter):
I have an issue where after a cold start the engines idles a little higher than I'm normally used to. I think it idles at sub-1000 RPM, but now it's more like 1200-1500 RPM. Adding to this it seems to vibrate/throb every 2-3 seconds. It's very slight and unless you've been driving the car for a while you'd probably wouldn't notice the change. I'm used to a steady idling, so this pulsating sensation is new to me. Once I kick it into drive the car is perfectly fine, idles at 500-600 RPM at stop lights, etc., and starting it up after running errands after a few hours in the store yields no problems either. It only happens after a really cold start, say 8 hours or so.
I took it to the shop, all they could find was a slightly under-voltaged battery which they replaced, but the issue still occurs. The only thing I remember doing different around the time frame of when this started happening was add STP Multi-Purpose treatment into the gas tank. I can't imagine a fuel additive having such a dramatic impact though, but who knows.

My 2004 Santa Fe 2.4L manual transmission with 200,000km on it has this hard to explain noise when in gear and coasting. This is when my foot it off the gas and say I'm going down a slight incline. There is a pulsating humming noise, worse in the lower gears that coincides with the engine holding the car back. This only seems to happen during coasting and not when down gearing to slow down. And even when coasting if I press even ever so slightly on the gas so the engine is not holding the vehicle back, it goes away.
The clutch has never been replaced and I'm somewhat assuming it may be the clutch becoming worn.

what would cause a pulsating rough idle when in park with the defrost or a/c on? when I turn it off or to any other position it's fine even when I turn if off it's fine as well? there is no Check Engine Light showing at this point.

I am having a crank and no start issue for a while now In Cold Temps -20 Celsius Or Colder... dealership checked fuses and relays they came back fine. there was an active CEL code for Low System Voltage would that have something to do with my problem here, and what else could be the problem? this has happened in the past after short 2 min drive and go in the store and come back out from being in the store for a few mins, eventually it does turn over but not without alot of cranking and curse words, until now I just found out after a longer 20 min trip it did it again, telling me its getting worse. 2006 Hyundai Santa Fe / 205,000 kms....

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!.. ??

Just recently my 2004 Santa Fe 2.7 V6 started having problems when starting on cold days. I live In PA and it just started to dip below 40 degrees. When I go to start my vehicle it will crank over longer like its is not getting fuel or something else. It will eventually start and when I turn it off quickly it will start up fine or after it is warm it will start up normal. When the vehicle sits for some hours and its cold outside it will have trouble starting again. The battery is fine had it tested and cca are just below what the norm is for the battery. Today the temperature was 52 and the vehicle started up just fine with no hesitation or prolonged start.
Another thing that happens when its cold out is right after you put the vehicle in drive and give it gas to start moving it will chug a couple of times before it will have full power then its fine. This has only been happening in the winter. I didn't have any problems with the chugging in the summer.

I have an issue for the last couple of years. I drive a 2006 hyundai santa fe with 168,000 km's on it. the problem I am having only happens on any cold day and never above zero celcius and when I start the vehicle on a cold day and go for a short trip to the store run in for about 5-10 minutes and I come back out and it won't start, there is lots of power but it wont roll over at all but after trying many times it will eventually start and there is no CEL showing and I have never plugged it in on a cold day and as cold as the canadian winters get here its been down to as low as -40 in the morning and no problems at all, a little roll and a groan and away she goes which is typical in our cold climates.

New here - 2004 Hyundai Santa Fe 2.4L Autostick//great car so far, but this is annoying me!
I can't feel any vibration, I just bought the vehicle and wondering where this noise might be coming from? If you rev the engine over 3k there is a strange vibrating/humming/rattling?? noise but you can't feel any vibration. I was thinking it might be the plastic cover on the engine or maybe something loose? I've already had the belt tensioners/belts checked out and that is not the issue.
It also sounds like a ricer when accelerating heavily (but from inside the cabin) there aren't any exhaust leaks at least I don't think so...

I bought a 1996 Lexus ls400 last July to extend the life of my Santa Fe. So during the summer months, I've hardly been driving the SF. My problem is that if I don't drive it for 4 to 5 days, I get a tapping noise on start up and it continues for about 3 to 4 minutes and then totally disappears. As long as I drive it every other day I never hear that sound. Not sure if this is a recent development or has always been there as the SF used to be my DD.

I own 2005 Santa Fe. Vehicle is a 3.5l V6. 90,000 miles. Transmission flushed few months ago. Few weeks ago I notice that transmission jump hard and bucked on cold start then smooth out once the engine warm up. Is it normal? if not what could be a problem.

2009 F150 STX with 4.6L 3 valve engine. When first started there is a pulsating sucking noise (sounds like a small vacuum pump at where I work) that has started to come from under the hood. Only does this for about 10 seconds or so and then goes away. The colder the engine is when started the worse it is. I have also noticed that about 10 or so seconds after you shut the engine off you can hear a valve of some sort opening up and a rush of air. I think this is coming from the passenger side by the radiator. Where this sucking noise is coming from? And is this valve release at the end normal? The truck has about 48K miles on it so don't know if this would be a warranty thing or not.

In my 2005 elantra GT 5 speed, I get a weird pulsating vibration in 5th gear at 45-50mph. It's noticeable enough to have a friend ask me about it. But it's very slight. I have 124k miles, and a new clutch. I've only had the car for a couple weeks so it's still new to me. My first inclination is axles or a wheel bearing. Maybe a motor mount. But then again, only in 5th?

I have this weird problem where my cars blows air at all speeds but the AC and heater doesn't work, what it could be? Maybe blower motor relay?

I currently own a 2003 Hyundai Santa Fe with 135,000K miles on it, and have had continual problems with the A/C not blowing cold over the last year or so.
A year ago, took it to what I thought was a reputable mechanic (not a dealer) who diagnosed the problem as a "bad" master circuit board. Thing ran fine for about 6 months, then started to intermittently blow warm air, until it finally quit blowing cold.
Finally broke down and took it to the dealer hoping they would be able to fix the problem. They charged me $110 and told me the refrigerant was low so they topped it off. 6 weeks later, once again not blowing cold, took it back. They said this time they found a "leak" in the refrigerant hose, replaced the hose, topped off the refrigerant, and sent me on my way (free of charge, of course, since they should have fixed it the first time).
Well...6 weeks later and once again, not blowing cold, so back to the dealer I go. Once again, they said the hose was "leaking" and they did the dye test (shouldn't they have done this the first time?) and replaced the hose, and the refrigerant. Good for another 6 weeks, then once again, not blowing cold.

I have a 2003 Santa fe 2.0 diesel which I got 2 weeks ago, but the air con does not blow cold, I suspect that the air conditioning needs re-gassing, my question is how often does the air con need re-gassing on the santa fe, I've had cars before and for a number of years and the sir con always have been fine, I just hope it needs a re-service , are there any common faults with the air cons on a santa fe?

I am after to find which USB cable and software can be used on my wife's ... 5/05 v6 Santa Fe to check the error codes. The car is revving up and down when cold and lacking power when warmed up, I'm guessing it's a sensor but I need to find which one.

My engine in my 2002 Santa Fe 2.7 v6 has been making a ticking sound that was especially pronounced when cold starting. It would quiet down somewhat when warmed up but still a slight ticking would be there. I thought it was the hydraulic lash adjusters. I know Hyundai's service site sates that a ticking can be heard if the factory filter is not used. I tried using the factory oil filter which did not make a difference. The car had about 85,000 miles on it and I always maintained it well as well as keeping up with oil changes. I took it to the dealer to have a repair performed related to corrosion of the rear trailing arms and had the tech check the engine noise.
It was determined that the cam chains have developed slack and were slapping on the cam chain guides which prevent the cam chains from popping off in case of slack developing which was the case here. The chain guides are made of some type of plastic material and according to the tech showed significant wear. This was all covered under the powertrain warranty. For those that are not under warranty any longer and are capable of doing their own repairs this is the list of parts that was ordered by the dealer. The parts in red are the culprits. The rest are gaskets and seals. I don't think this is an easy job.

It's my 2005, 2.7l. auto trans, FWD.
AC stops blowing cold when the engine temp get hot. As long as the car is moving, it blows nice and cold. Also, when sitting the engine temp rises quickly and will over heat if you don't get moving.
Cooler fan on the inside of the radiator never kicks over to high mode as the temp goes up. I checked the fuses and the relay and both are good.
That leaves me with a bad fan? Correct? Also, what is the part number of the fan?

Its been getting quite cold here lately at night and in the morning when i go to the santa fe it makes a ticking noise for about 2-3 seconds and everything is fine again. I was thinking of dropping a quart of transmission fluid in the crankcase run it for a bit and change the oil?
