Santa Fe (CM - 2007-12) :: Engine Will Do Slight Rev Up / Down When Cold
Apr 25, 2013
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.

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.

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.

I've noticed that on cold starts after work, or in the mornings in start up my Santa fe's really rough at idle.. I'd like to say even slight hesitation when I take off.. I notice a drop in RPM and lately harder shifts out of first..
My sf is the 3.5 AWD w/ nav it's a month old with 2900 Kms on it..

I have a 2007 Santa Fe GLS AWD that has a rear driver side tire problem. It starts after roughly 10 minutes of driving as a slight squeal. It starts at around 20mph and will quit when I reach 40mph. The longer I drive, the louder it gets to a point where it is almost constant between 20-40mph. It stops when I apply the brakes or when I turn slightly to the left or right. Also, if I stop and turn the car off it takes 5-10 minutes for the squealing to start again. There is a smell of hot metal and sweet smell coming from the area.
I had the rear brakes and rotors replaced 12,000 miles ago, and them checked at my local Hyundai dealer when I first noticed the squeal and the mechanic said the brakes and rotors in the rear did not need replacing. What it could be?

My 2011 Camry LE I4 with 21k miles has a slight knock after cold startup, at Idle for a few minutes that disappears after warming up. If you start and drive and don't let it warm up the knock, under load, is more pronounced.

I have a 2003 Mitsubishi Diamante that I have owned since 2008 purchased it with 60,000 miles on it. Currently has 131,000 miles. I have always kept my car in good running condition and performed all of the scheduled maintenance per the owners manual. Last month I noticed a slight cold knock on the right side of the engine that would go away when the engine warmed up. I checked the oil and noticed that it was a little bit low (maybe half a cm below the lower threshold on the dip stick). I added oil and continued to drive it, still knocking.
Bought some sea foam thinking it was the lifters and sprayed a can in the intake and poured some in the oil. Then changed oil with 5w-30 synthetic, have been driving it for about 500 miles now and the cold knock seems to be getting worse and I can faintly smell burning oil when it is idling as I let it warm up before driving off. By the time I get to work the knock is essentially gone. My oil levels have been fine... My question is, should I be explaining to my wife and fiscally responsible self, that I need to be looking for a new (read used) truck sooner than I had initially planned? Or, is this something that can/should be addressed or just drive it until it gives out...

I just bought a 2010 Santa Fe. All seems fine except that when the car is cold it goes into R harshly (with a bump and a small delay)and also is a little bit irregular in normal gear. I'm used to have cars with transmission problems unfortunately and happily it's nothing like that but I'd really finally like to have a vehicle without any tranny issues.

I have a 2007 3.3 with 42K miles on it and the AC just started passing air that's not quite as cold as it used to be. When its at idle I would say its a mild cold and then when driving its the same mild cold but with more force. Understandably today is really the first hot, humid day of many to come so I was wondering is there any good indication that its just low freon with a leak or the compressor is going or is there any adjustment to the belt in case its just slipping? I did it drive it for quite awhile and it never improved. I would hate to drive it more and ask for a bigger problem.

Well its the coldest this SF has endured while in my barn. It was -23C last night or early this morning went we got up. -19C now but it doesn't warm up with a slight change sitting outside. I started it ok but these newer vehicles sure make a lot of whining and other noises when its this cold until they run for a minute they quiet down.
My old Grand Cherokee was a lot quieter even with near 300k on it it. But my wife's Jeep Compass a 2009 made enough noises as well. Both have synthetic oil in them. I just don't like hearing all that and wonder what its like for you that are in much colder climate with your SF since -30 to -40C is common in other parts of Canada in the Winter. Just curious because it cannot be good and the PS pump must be one of the complainers I am sure.

I have a 2007 SF 2.7L V6 with 55000km.
Recently we have noticed that from a cold start the engine idles roughly few a short time and especially bad if put into gear only moments after starting.
Do we need to let it warm up for longer?

I have a 2012 Santa Fe and during the last cold spell, both myself and passenger felt a lot of very cold drafts entering the car through the door handle and door switches.

The vehicle has 80,000kms, and from a cold start it is having this problem more and more frequently. I must crank the engine 3+ times, and then she starts. A prolonged cranking period doesn't seem to work, and this only occurs when cold. The car starts fine when warmed up. I have scanned the car with a generic OBD2 reader and there are no codes. Once the car is running, it runs great with no misfires.

I have had some slight rough running with a cold engine and stumble <2000rpm. Finally it tripped a CEL which was read as a misfire code.
The mechanic swapped the coil and plug(recent) and no change. He did a compression test and air blew out the exhaust. So.......the car needs a valve job which entails motor removal and fixing the head and reinstall. He rough estimates this at $2000 and rate is $65/hr.
He mentioned looking at pistons and may be a bit more if rough.
This car well maintained (170,000 miles 2005 Legacy turbo wagon with manual)...

I've got a 2003 f150 with the 5.4 and 128,000 miles with an engine tick. Its not an exhaust leak I know that for sure. It has came up in the last 20,000 miles. I've used motorcraft 5 20 w/ motorcraft filter. I've tried a kreen engine treatment with no change. Heres the description/syptoms:
-Slight clatter for 2-3 seconds upon cold startup (happens very rarely)
-top end ticking that is loudest and most noticable when warm (quieter when motors cold)
-not timing chains/tensioners etc because the noise is coming from the top end and most noticeable on the passenger side.
-at idle the tick is present-when you rev at idle, the noise goes away.
-Driving (or having the engine under any load for that matter) the noise gets louder.
-Anytime I accelerate, tow/haul, go up an incline the noise gets worse
-Sounds like a "whirring" sound from within the dash.
With all that said I am thinking the lash adjusters are getting noisy. I had a certified gm tech that has 40 yrs mechanic experience under his belt and builds prostreet muscle cars on the side look at it. He listened to it to it and that was his diagnosis as well as its not that bad so just live with it. The noise at idle doesn't bother me, its when im driving with the windows down. The noise drives me crazy and is a little annoying to me.
Heres a link to a video of the sound and keep in mind it is much louder now : Triton engine noise/tick - YouTube

Cannot figure out how to get the heated air to flow through the back via the rear vents. All I get is outside air. I cannot find anything about it in the manual. The dealer has no clue but is trying to find something on it. New 2009 Santa Fe Limited.
