Santa Fe (CM - 2007-12) :: 2009 - Subtle Fluctuations Or Surges In Engine Under Both Acceleration And Cruising Speed

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.

Camry :: 2009 / 4 Cylinder - Check Engine Light And Sluggish Acceleration

My wife called to tell me that her Camry would barely pull away from a standstill this morning. Very sluggish until about 2500 rpm, at which point she said it took off normally. This accompanied by the Check Engine light, which just appeared this morning. I haven't been home yet to check fluid levels or take a test drive. Anything in particular I should be looking for?

Santa Fe (CM - 2007-12) :: 2009 - Speed Related Noise On Acceleration And Hills

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?

Santa FE SM (2001-06) :: 2004 2.7L V6 2WD - Codes For Sputtering / Sluggish Acceleration

2004 Santa Fe 2.7L V6 2WD ... Car was running fine, filled it with gas, and upon starting, heard a backfire into the intake manifold. It coded for a Cylinder 3 misfire so I had plugs and wires changed.

Now...The car starts, idles rough, accelerates sluggishly, and running rough any time it was around 2000 RPM. After I changed the plugs, it started bucking a little and stalls when I take off in the morning.

Coded and it's reading 7 codes, but some are duplicates:
-P0274 Cylinder 5 Injector Control High
-P0305 Cylinder 5 Misfire
-P0102 MAF or VAF A Circuit Low Input
-P0050 H02S Bank 2 Sen 1 Heater Circuit
-P0030 HO2S Bank 1 Sen 1 Heater Circuit
-P0274 Cylinder 5 Injector Control High (Shows Twice)
-P0102 MAF or VAF A Circuit Low Input (Shows Twice)

After having a backfire and then cylinder misfire...replacing the plugs and wires.

Santa Fe (CM - 2007-12) :: 3.3 Engine AWD - Rough Acceleration

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.

Mazda :: 2007 - Sluggish Acceleration / Stops When Foot Is Off Accelerator

I have a 2007 Mazda 5 and over the past few days, I notice the acceleration seems slightly sluggish, especially on inclines. Then last night I had a problem where I was driving and whenever I took my foot off the accelerator, the car would stop (rather than gradually slowing). And when I put my foot back on the accelerator, the car jerked forward before finding the right speed. I parked and after work, it drove just fine. Drove fine this morning also. The shop says I need a new solenoid purge valve, but after reading about that valve, I don't understand how it could cause my problem. The car didn't stall whom it stopped, it just stopped moving forward.

Santa Fe (CM - 2007-12) :: Sluggish To Shift From P To R / D - Inhibitor Switch?

Model is 2008 Hyundai Santa Fe GLS 2.7L

A month ago I started noticing it was sluggish to shift from P to R/D but i had no issues starting in P mode and the car would drive fine. I thought it might due to cold weather so didn't think of it too much.

Two weeks ago it was really hard to shift the gear from P mode and I nearly got stuck in middle of the road unable to shift from R to D. I applied a lot of force on the shifter and it finally budged into D and car drove with no issues. I parked and did my chores came back and the car would not start at all.I put the car in N and it started and was hard to shift back in D but I drove home without any other issues.

It died again in my drive way but this time the gear was nearly impossible to shift and I thought I almost broke it and the panel was not registering it was in P and the key was stuck in the ignition. After messing around for some time I was able to get it into N and put my hand brake on left the key in the ignition and disconnected the battery.

Today I opened the center console & battery tray these are my findings. The inhibitor switch was slightly misaligned from the N position.

1. The shifter moves freely once the linkage is disconnected by removing the tiny pin.
2. The inhibitor switch was slightly misaligned from the N position. Once I manually adjusted it I was able to start the car.
3. I reconnected the linkage pin, make sure the inhibitor switch was in N position and started the car but it was again nearly impossible to switch to P/R/D
4. My brake lights work fine.
5. I was able to remove the key once I completely disconnected the battery.

What can be the issue here ? Inhibitor switch ? The shifter assembly ? Linkage?

Prius (2010-12) :: Engine Choked Off - Sluggish Acceleration

Lately I have found that when I am trying to go up an incline on my road, that my car has trouble accelerating. Almost as if the engine is being choked off like it is about to stall or is out of gas. I have to press the accelerator almost to the floor to get up the incline. The suddenly it will lurch and accelerate rapidly as if I have put the car in Power Mode.

I should also add that this only happens when the engine is cold. I didn't have this problem last year at all. I usually wait a couple of minutes after the engine starts before I try to drive, but that doesn't seem to work.

Cadillac - Deville :: 2003 - Service Engine Soon Light / Sluggish Acceleration

I have a 2003 Cadillac Deville with about 120,000 miles on it. The SES light came on and I had some maintenance done at STS. The light came back on the night I picked it up. I took it back the next day, they said it was related to the transmission and they do not do transmission repairs. They cleared the light and said if it came back on they could flush the transmission and maybe that would take care of the problem or they suggested I should take it to a transmission repair shop. The error codes are p0741 & p1860. Once in a while at the beginning of a drive I experience a sluggish acceleration, it does not last long( a second or 2) and then runs fine for the remainder of the drive.

Santa Fe (CM - 2007-12) :: 2009 V6 Engine Knock While Starting

My 2009 Santa Fe (2.7 L V6 GL, 5 months old 7500 kms) just recently started making some very pronounced knocking noises on startup when the engine is cold. It never did this before and only lasts a minute or less, it's not that the engine itself is very cold since I keep it in a heated garage all the time when it's home, but when the engine is starts first thing in the morning it's very noticeable.

I have an appt. at a dealership tomorrow to get it checked, outside of an oil change I never dealt with these guy's before. What it could be? It's full of oil which they just changed 4 weeks ago.

Santa Fe (CM - 2007-12) :: 2009 SE Stalling / Engine Shuts Off

We've had this 2009 SE with the 3.3 since brand new, and have had the engine shut off/lose power out of the blue while driving 4 times over the years.

Each time we were able to pull off the road, shut off the ignition, then restart and have it work normally but the odd thing is that there hasn't been any codes or CEL on etc. so when we take it to the dealership they run diagnostics, and say "no codes, no problem" which is beyond frustrating.

How to get to the bottom of what's causing this?

Santa Fe (CM - 2007-12) :: 2009 - Transmission Shifting Is Not As Smooth As When Engine Is Hot

When I start the car for the first time of the day, the shifting is not as smooth as when the engine is hot. Is this normal ? When I checked the trans fluid, it was between 25 and 75...(the second little mark on the dipstick) but I just drove about 5min so maybe the engine wasn't warm enough..

I have a 2009 Santa Fe that when the engine has warmed up, the engine starts making a ticking/clicking noise. The dealership told me not to worry all cars make that noise and it was probably just a purge valve. Does this sound right?

Santa Fe (CM - 2007-12) :: 2009 - Check Engine After Timing Belt Replacement

I have a 2009 Sante Fe with 60,258 miles. I had the timing belt changed at 60,000 miles at the dealer. I now have a check engine light that shows the following two codes.

P0321
P0612

These codes are related to a timing belt change? Could a sensor have been removed for the work and not replaced correctly?

Santa Fe (CM - 2007-12) :: 2009 - Loss Of Power When Engine Is Under Load At Highway Speeds

We have had had our Santa Fe for a year, done 38000 km and love it. The car will start up and drive around town fine but as soon as the engine is under load at highway speeds or driving up a hill it loses all power.

In Automatic when this happens the gear will drop back to third. You can switch it over to manual mode and slowly accelerate back up to around 80-90km/hour with your foot flat to the floor but the rpm don't get above around 2000 to 3000.

If you stop and turn the engine off for a minute or so, when you start again everything will appear to back to normal but after another minute or two the problem will be back. The engine malfunction light comes on and sometime it's flashing but at other times it's constant.

The car's been in at our local Hyundai dealer for a week but at this stage they still can't quite figure out the exact cause of the problem. The code they pulled out suggested it was the exhaust particulate filter (apparently quite an expensive part) so they replaced that but it didn't fix it. They've also replaced the fuel filter and some temperature sensors that are part of the particulate filter apparently but still no joy.
