Santa Fe (CM - 2007-12) :: Squeal From Engine On Cold Startup
Mar 11, 2012
Twice this week our 2009 SantaFe (3.3l) had a squeal from the engine upon cold startup. The first time it was very cold (-20C or so) and this was louder and longer than the second time (-10C or so). The squeal lasted only a few seconds and trailed off to nothing. Each time the heater controls were set on defrost (fyi). In order of likely suspects, I suspect one of the following:
-compressor engaging and causing sudden increase in resistance on the belt or compressor engagement clutch noisy
-idler pulley for some reason causing belt to slip at first, but don't suspect idler bearing as noise disappears right away
-belt slippage due to resistance somewhere else--e.g. water pump or alternator.
This may not happen when I take the vehicle in for its next scheduled maintenance as by then the weather will likely be warmer. This has 76000 km on the clock.

Bought 2009 santa fe new [3.3]. after cold start up tac is moving up and down and it seems to be missing. After temp is reached tac is steady but there still seem to be a hesitation when driving. 21,000 miles on vehicle. could it be a bad tbs?

I've isolated this rattle down to the cam phaser( CVVT) in the right cylinder head. It rattles bad for 2-3 secs on cold start or after it sits for 3 hours.
I've put in 5w20 synthetic oil and synthetic Lucas additive and it cleared up the noise for short interval start ups.
I changed the cam phaser in the right head with a used one ( 40k ) but it didn't make a difference. I should change out the attaching cam as well.

I have santafe 3.5 2012 4WD , it's 51K on odometer, the problem when cold startup , Noise and small vibrate form front side , its look like from gears
When put to reverse (R) sound is louder and strong vibration from front side, all this problem gone when drive about 15 minutes.
I have visit 3 local shop they check the engine, gear box, everything normal, no check indicator appears.

This morning during cold start up I noticed my check engine light was on constantly, I was able to get a OBDII scanner from a friend and perform a scan after work and brings up P0116, google search says HYUNDAI - Engine Coolant Temperature Circuit Range/Performance.
I did notice the radiator fan seemed to be running all the time. I had a look at the coolant level and it's near the full level line (green color if that matters). My questions is it safe to still drive it to the dealer (30 km away)? Would this be part of the powertrain warranty?
Since my wife is out of town i took her car as I did not want to cause any damage.
2013 Hyundai Santa Fe Sport - 2.4 AWD - mileage is at 67,000 km.

I recently bought a 2011 460 L, CPO with 28,350 miles. I love the looks and how it drives, smooth! But I do have a concern. Before I go to the dealer I thought I would educate myself from the experienced LS owners. I am hearing a very brief (1-2 seconds) mild engine knock at a cold startup.
This only occurs when the engine is cold and has sat overnight. It never happens after this first startup, even after turning the engine off and then on again. It kinda sounds like the oil isn't getting where it should be for a few seconds. Engine sounds great with normal and hard acceleration throughout the day. The dealership where I bought it is 300 miles away, so I would be taking it to a local dealership.
Now I did hear this noise and mentioned it to the service manager when I first bought the car, and the service manager told me that this cold startup sound is normal. He also mentioned the direct injectors at idle. I guess sometimes it's hard to fully trust what dealerships say. Is he right?

While we continue to enjoy our recently acquired Mineral Gray 2011 Santa Fe, I have noted a momentary engine noise upon startup after it has been shut down for say 2 hours or more.
The noise reminds me of having an oil filter with a malfunctioning or absent drain back valve where by the bearings will complain for 2-3 seconds until oil pressure rebuilds
The SF has but 20.7K miles on it to date. Do we know of this is usual for the V6, or should I be concerned and planning a dealer visit?
I love the power of the V6! We test drove a 4 cylinder model first thinking that was the way to go for economy reasons. I found this one with such low mileage, AWD, and the V6 at a great price so we jumped on it.
I am a little disappointed though that the AWD does not function "full time" like that on my 04 Dodge Durango. The SF runs rings around the Durango in the mpg department though.

For the past year or so my Santa Fe (49,000KM) the engine will knock for 5-45 seconds when I start it up after its been sitting a while. I asked the dealer and they said this is "normal" and cannot be adjusted.

I have an 07 SE (manual transmission). In cold climates has noticed a noise at startup on a cold engine when the temperature is below freezing (colder than -5C or so)?
The engine has to be cold (like sat overnight) and the outside temp has to be cold. Then at start when I turn the key, the engine starts fine, but as I release the key from the start to the run position I hear what sounds like the starter motor make a noise (short zipping sound).
At first I wondered if it might be slow to disengage, but if that shouldn't make a noise because the gears should be meshed ok? There is no noise with a warm engine, or with a cold engine on a mild day.

To start off with I am not car smart! I have a 2008 Santa Fe 3.3L V6. Last year about this time (December) I had problems with the vehicle upon start up would be miss firing and the check engine light would come on. I would turn the vehicle off and restart and it would be fine and not happen again sometimes for a week and sometimes for months. I hooked it up to the computer and found that it was missing on the #6 cylinder. I had the coil pack replaced and that seemed to fix the problem (replaced spring 2011). About a week ago it started doing the same thing (December 1). Upon initial start up when the car is cold and the outside air is very cold it started missing again and having a rough idle. Would turn of the car and restart and would run fine but check engine light would come on.
Hooked it up to the computer once again and it read random misfire. This has happened twice now in two weeks with the same reading each time. Always when it is cold (engine and outside temp) and seems to reset itself when turned off.
I spoke with a mechanic who recently had this same issue with a different vehicle and after trying many things replaced the engine coolant temp sensor and that did the trick. He said it was a cheap start therefore i bought the part and now am looking to replace it. The only problem being i am car dumb and cant find it. I have done many searches and the diagrams i have found don't do me any justice. The past posts on here have given pictures of older models that dont match what i am looking at. It probably is right in front of my face. Any picture of a 2008 that will show the correct area I should be looking at? The vehicle only has about 57,000 miles on it.

My car is an 08 AWD 3.3 I am noticing the engine will do a slight rev up, down, up, down when cold almost daily when I leave work in the afternoons.
I removed the airbox and intake tubing, cleaned the throttle body with TB cleaner and mass air sensor with electronics cleaner. I also used about half of a bottle of seafoam in one of the vacuum lines to the engine, and the other half in the fuel tank. Also ran some Chevron fuel system cleaner in the fuel tank. Nothing seemed to make a difference. It still persists.
It's noticeable the most in neutral, you can watch the tach rev up from 800 rpm to about 1100 and back down repeatedly. If the car is in drive and the brake is lightly applied, it will want to move when its revving up.

I've been experiencing ENGINE RPM FLUCTUATION on cold starts. I took it into the dealer and they found an update available for the ECU and reprogrammed the ECU.
2009 Santa Fe ?
So far it appears to have corrected the RPM Fluctuation on a cold start... I see TSB 10-FL-010 cover this but also suggests to replace the Throttle Position Sensor which wasn't done on my vehicle.

Having an issue with my 2007 Santa Fe 3.3L. When the engine is cold, been sitting for a few hours not when the temp outside is cold, it takes about 5 to 8 cranks before the engine will fire. I can then shut it off immediately and start it again and it will fire right up.
I currently have the P0464, P0463 and P2068 check engine error codes for the fuel level sensor units. I don't really know if these are directly related as I've had them for about 6 months and the starting issue has just shown up the last month or so. Plus, I would assume these should only be related to sending fuel level information to the fuel gauge. Either way, I'm still leaning toward a fuel delivery issue since it only has a hard time starting when the car has been sitting for a few hours. I don't know if maybe it's the fuel pump or a electrical component. If it's the fuel pump, I'd like to do that when I take care of the sending units so I don't have to go back in. I've tried turning the car to the 'on" position for about 10 seconds without starting it to see if I could get the pump to load the line, if that's the issue, but it doesn't seem to make a difference.
The battery is good. It tested 12.5v after sitting over night.

07 Santa Fe 3.3 with 155k miles has lifter noise all the time. Much more pronounced in cold weather upon start up when the engine is cold. These miles are mostly highway and I change oil every 5-6k with Citgo synthetic blend. Is this just normal wear or could the engine be getting gummed up? I was thinking about treating the engine with some Marvel or Rislone but I really don't like putting solvents in my crankcase.

My 2.2 crtd is the first ever diesel car i have bought, but i have noticed a whine especially when cold, pitch bieng raised as engine revs. Is this a characteristic of this car or am i in for a bill further down the line.

I just installed new brake pads in my 2WD 2009 Santa Fe. I bought the cheapest AutoZone pads. Now I have a loud squeal sound when I apply the brakes. If I apply a hard brake the squeal goes away. Until I apply the brakes again. Now, after install...I have been researching and noticed that the stock pads are ceramic. I did apply (Not once but twice) break grease on the pads. What the problem might be? Oh yeah, I did see that after 2007, oiling the caliper springs is required and might be the problem too. But I do not know where the spring in question is and how to oil it.

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?

I've already replaced the Alternator and Water Pump today and I still cannot get rid of the noise and cold start squeal. The squeal goes away after the engine is warmed. A/C Compressor?

As the weather is getting colder I noticing again my RPM's taking longer to drop down to 1200 or less. Upon startup the engine rev's to 2000 and drops in 2 sec quickly to around 1500 (all these are based on the crude gauge readings, not a digital tach).
I don't like high RPM cold starts in the first place and why its stays just around 1500 and lower for about 2 minutes before it lowers to around 1200RPM. I don't like engaging the transmission at those high RPM's. My other vehicles did nothing like this and the increased start RPM was down 1000 within a minute.
What sensor is having the computer run it like that and not let it drop faster. I doubt its the O2 sensor since its the same on a hot day just doesn't rev up to 2k but 1500 or so. Jabs at the gas pedal doesn't work it drop any sooner either.

I get a small "squeal" from the engine usually only when it's cold out, and have narrowed it down to the water pump pulley (2nd pulley down from the top). I put a drop or two of WD-40 on the "rod" that runs through the pulley and it stops. I know not to put anything on the belt to avoid contamination but it seems to me that it's the metal bolt that keeps the pulley in place. I stopped by an O'Reilly and had the tech have a look because I was going to try a more viscous grease. He thinks that it's either the pump is starting to fail or that the pulley could have moved out of place. He said I should remove the belt and tug on the pulley.
If it moves then it's loose and needs to be lubed and tightened. If it doesn't then it's a water pump replacement. What do you all think? I don't want to drop a ton of money as it truly only squeals when it's cold, and unfortunately I'm thinking Chicago's gonna have a cold one this year even though after the engine heats up it's goes away. If you have a guess to the problem, what do you think replacement will run me. I'm only at 30,000 miles, and has been garaged until recently so I don't think it's a belt change or pump failure yet.

On cold starts the engine makes a continual squeal. Within minutes if I drive it or simply rev the engine a few times the sound is gone and the engine again sounds glorious. If I spray the belt with water the sound immediately ends. I have replaced the water pump, belt tensioner roller, idler rollers and of course the belt. All to no avail. 2005 Porsche 911...
