Santa Fe (CM - 2007-12) :: 2009 - Subtle Fluctuations Or Surges In Engine Under Both Acceleration And Cruising Speed
Oct 16, 2012
I recently bought an '09 Santa Fe Limited. I want to love the vehicle, but I've got a problem with how it drives. Basically, here are the symptoms:
1. Engine RMPs dance around about 200 RPMs at idle. (I was told this is normal. I don't think it should be.)
2. Under normal acceleration, it bogs down immediately after shifting into 2nd gear and after a couple of seconds there is a surge and acceleration seems "normal."
3. Occasionally, I feel subtle fluctuations or surges in the engine under both acceleration and/or cruising speed (any speed, really.) It's like I'm feathering the throttle when I know I'm not. This is most pronounced when under a load, such as taking off from a stop sign at the bottom of a hill and accelerating up the hill.
So, here's what the dealer has done to address the issue.
1. According to the Carfax report, the previous owner had the throttle position sensor replaced at 22,000 miles and again at 27,000 miles. I bought the vehicle with just over 30,000 miles (certified pre-owned).
2. On the day that I bought the vehicle, I noticed the issue and the service manager took it for a test drive with me. He told me it was wind buffeting that I was feeling. I thought that was bunk, but with it being a higher profile vehicle, it put some doubt in my mind. He went ahead and flashed something to reset the adaptive learning module that supposedly adjusts something in the engine based on how you drive. It seemed better after that, so I went ahead and bought it.
3. After a few weeks of driving it, it became clear to me that it was definitely not wind buffeting, so I scheduled a service appt. It was taken for an "extensive" test drive (according to the service record) with a diagnostic computer connected. Apparently, the service technician said they were only able to find one small blip with the mass airflow sensor, so they replaced it and called it fixed. I should also note that at no time, have any codes ever shown up when they check for error codes.
4. Although it seem slightly better, the problem still exists. Just for kicks, I dumped a bottle of Seafoam in the gas tank with my last fill up, but that doesn't seem to have made any difference.

I took my 09 6 cyl. AWD Santa Fe Ltd. into the dealership this morning because of a whoop whoop whoop noise when accelerating normally or maintaining speed on a grade. A bit like a helicopter sound. The frequency of the noise increases with speed and seems to come from the front driver's side. I thought it might be a wheel bearing.
$2000+ later I have new tires, a 4 wheel alignment, new rotors and pads fore and aft, a new tie rod end and a car that goes whoop whoop whoop when I accelerate or climb a hill.
The car has 125,000 km. (78,000 mi.) on it and has been very well maintained. Detonation maybe?

Our FWD Santa Fe Limited had a very noticeable vibration that started around 60mph. Oddly, the vibration will sometimes come and go while cruising at a constant speed on the highway. We went about 30k miles before we had time to get it into the shop.
I asked them to rotate and balance the tires and the vibration was noticeably reduced...initially. Now it's back!
The car has ~65k miles. All 4 Kumho tires match and I believe are original from the factory. I have kept all tires inflated properly.
Our car has the optional 18" wheels. Is it common for these to bend? What else could be the cause here?

My '90 Ranger is experiencing a pretty bad misfire after doing a tune-up. I changed the plugs (gapped to .045), wires, distibutor cap, rotor button, air filter, fuel filter, and cleaned the IAC. It had a barely noticeable miss before the tune up, that's why I did it. Now, it's pretty horrible.
At idle, it's definitely noticeable, and at cruising speeds (RPM's below 3K) it bucks and surges. The weird part about it is WOT runs are as smooth and (somewhat) powerful as ever! At idle in neutral it will revv up just fine without any hesitation as well.
First thing I did was check the firing order, again and again. Made sure all my wires were properly seated on the plugs and on the distributor prongs. Pulled the plugs back out, they were all clean and properly gapped. I pulled the wires off one by one to try to isolate the misfire, but every plug wire I removed made around the same impact on the motor.
Next I ran codes. KOEO, I got code 95 - fuel pump secondary circuit failure. Don't know what to do about this. Fuel pumps comes on at the turn of the key, relay clicks... KOER, I got 11 (pass code), so nothing there.
Then I hooked a fuel pressure gauge to the schrader valve on the fuel rail, and at idle pressure was a steady 35 PSI. I also removed the vac. line to the FPR while running to see if gas came out. I checked for vac. leaks as well.
Now not sure what to check now. I've checked everything I know to check, but nothing works....

Experienced sluggish acceleration with their "09" Santa Fe. I have the 2.7 liter 6 cyl. engine and it seems so sluggish when accelerating. I have replaced all the plugs with some best rated ones specific to my model. I have tried one of the best rated fuel system cleaners. It still seems to have no pep, my daughter's 1999 Honda has far more get up and go.

Check engine and tcs light came on solid. Rough idling and rpm fluctuations while cruising. Brought it to toyota and they scanned it revealing a P2195 code: bank 1 air fuel sensor stuck lean. So what I'd like to know is; How long was the vehicle in the shop? What is involved in repairing this problem?

My wifes 08 santa fe awd has started to make a subtle clunking that I can feel through the gas pedal. At first I thought it was the AWD system but now it seems to be getting more frequent and noticeable.
I have searched and see that the front stabilizer bars have had issues with this year. Is the thump I am experiencing possible a sign of this?
If so how long would that be covered under warranty. The 3/36 has just expired on us.

My car santa fe 2009/ 4WD / 2,7 / around 70,000 kms. Around a week ago, I noticed some vibration, that I can feel it mainly on the gas pedal. I can assume that the vibration came from the front of the car and just at low speed, like below the 40km/h. Also I feel that when took my foot of the gas, the vibration gone.

I have a 2009 SantaFe Diesel and am having a few issues.
Firstly, of late it has been running rough when I back off the accelerator but hold the current speed. Almost like a mis-firing feeling. AT about 1500 RPM
Secondly, I was driving down the freeway recently, the car started to labour going up a long hill, so I tried to kick it back a gear using the accelerator but it wouldn't do it. It stayed in top gear and struggled. I had to manually do it with the gearshift.
About 12 months ago, I was having problems with the car completely losing power on a quick takeoff from standing still (say at a roundabout) but that seemed to fix itself.

Been having a very light vibration when cruising at speed as well as on some lower speed shifts and finally crawled under the truck today to check for drivetrain play. Other than the amazingly soft and sloppy transmission mount I noticed a TON of play in the driveshaft transmission yolk. Didn't feel like the u-joint but actually the tailshaft yolk. Dealer said on the phone they have seen this on a few of the newer trucks and it *should* be covered under the power train warranty. I have the subercab with the 1 piece aluminum driveshaft.

My 2008 Santa Fe 3.3 with 18,000 miles, developed an annoying surging when first put into gear after sitting overnight. I must keep my foot firmly on the brake as I back out of the driveway. If I press gently on the brake I can feel the car jerk or surge and show higher than normal rpms on tach. The jerkiness will go away entirely after a few miles and the rpms will return to normal at idle at a stoplight or stop sign. Is this something that would be covered under my factory warranty? Car was purchased Jan. 2009. I also notice that when the car starts in the morning it goes to a very fast idle. Is that normal? I would think that with the way the oil filter is mounted that the engine might have to wait for oil to return to the filter before it can get to the engine. What could be the cause of my problem? And is it likely my warranty should cover the repairs?

I have a 2009 Sante Fe, it has about 96000KM on it. It is a 3.3 engine AWD.
I find that when I accelerate the thing kind of feels rough. It is very subtle. Like you can almost miss it if I wasn't being so picky. But I can definitely feel something there. What this would be.

We have a 2003 Passat GLX, 43000 miles, V6, AWD. I've noticed recently that when driving at constant speed the engine will surge about once every second or two. It's very regular, and on a smooth road I can also notice a bump in the drive train, very similar to road bumps.
I've taken it to a dealer, since I believe it is a transmission issue, and therefor covered under warranty. There are no computer codes stored for faults in the transmission, they've said. However, they started by pursuing the fuel injection system (though no code was stored), and then wanted to fix a faulty coolant sensor (since found not to be faulty).

Still chasing a surge for some time while cold, mainly. While hot and cruising 65 mph the turbo still surges faintly.. but today was a different story, very fast and high surging from the turbo only, while on overdrive as usual. It calmed down as i dropped the boost a bit but it was quick swings of about 3-5 psi which is quite bad for what it had been doing which was manageable.
Short of taking off the turbo, I took out the VGT solenoid and it had some oil burnt on the end, cleaned that up and pushed the plunger in all the way a few times and it 'seemed' to have worked greatly, until today.
I pulled some other numbers;
KOEO
Map 13.7
EBP 14.1
Baro 28.2
Cold Idle
Map 14.0
EBP 16.5
Baro 28.2
When cold, mainly below 130F the RPM gauge itself will surge or hesitate around 1700-2000 RPM. Any higher or lower it will be smoother I suppose....

This engine unexpectedly surges from idle up to as much as 3 or 4 thousand RPM. It can be frightening. The IAC valve was buzzing loudly so we changed it out a couple of times with wreckers parts. With the third replacement valve in there, it hasn't surged yet but we are very leery to drive it for fear of uncontrolled acceleration while in heavy traffic. Is this a known problem or recall with these vehicles. I think it is ridiculous that the design would allow such a dangerous condition!

I did a search and what I saw all had to do with noise at startup.Mine is during cruising. I have a 2007 Sonata 4 cylinder with 112K miles. Within the last few months it began making a slight chattering noise when I accelerate and when cruising. It's worst around 55mph. When I let off, it almost goes away, but is loudest when I just am feathering the pedal to maintain speed.
If I put the pedal down a little more and accelerate, it is not loud, but still faintly there. At first I thought it was a tapping sound, but I've let some of my friends listen and its more like a clattering, metal rattling, or vibration perhaps. Its hard to describe. A week ago I had the check engine light come on with a "P0011 Hyundai - 'A' Camshaft Position Timing Over-Advanced Or System Performance Bank 1".
I changed the oil and took it into a local shop and they cleared the code/light and checked things out (the light hasn't reappeared). I had them take off the valve cover and make sure the top end was not making the noise. It seemed fine to them. They suggested I take it to the dealer for further diagnosis. I have not yet. It does not make noise during start up. If I have time I will upload a audio recording later. What may be making the noise? It seemed to get a little louder after the latest oil change, but that's probably me being more sensitive to the problem.

Cruising down the highway, my 2001 Santa Fe engine suddenly cut out. Would crank, but not fire. Not hearing a sound from the back when I flipped on the key, suspected the fuel pump, which I replaced. No go.
I'd pressed the fuel pump reset switch under the hood - checked it again. Should the switch, when it's pressed, stay in a locked position, like when you do a reset on a GFCI electrical outlet? Or is it normal for it to have the up/down 'play' in it?
Also noticed a strange buzzing on the other side of the engine compartment -- was the unit (don't know what it's called) that the throttle cable feeds into - hooks onto a pulley. The buzzing was intermittent and inconsistent, but it was happening with just the power switch on.
Oh, and did replace the fuel pump fuse, too. While it's at 280.000 miles, not quite ready to give up on 'er yet!

I have a 2004 Hyundai Santa Fe with a 2.7 4wd. It has started fluctuating the rpm's and is shifting erratically. I have seen on here that it is possibly the TPS. Does the same in manual or auto.

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.
