Santa Fe (CM - 2007-12) :: 2011 - Knocking Sound And Reduced Power

Last Saturday I had the oil changed at the dealer on my 2011 Santa Fe Limited V6 3.5. As I left the lot, I noticed knocking and reduced power. I went back in and they took it out for a drive and it was gone. The engine had been turned off and back on when before they went out. I went out with them again and it was gone.

Today I drove about 10 minutes, stopped and turned it off for about 10 minutes, and when I started it again and drove off, the knocking was back. It lasted about 5 minutes in stop and go driving. I might have been imagining it, but it didn't seem to completely recover until I turned off the engine and started it again (about 10 minutes in).

What can I do to narrow it down? I don't know what it is, but when I try to think what the symptoms are like, it's as though a cylinder is not firing. So far it has only happened twice and the first time right after an oil change. It has 50,000 miles on it if that's relevant.

Santa Fe (CM - 2007-12) :: Knocking Sound From D4EB Engine

I have a knocking sound from my D4EB engine (2008 Santa Fe. 120,000 miles)

Problem has been any diagnosis of the cause because the mechanics cannot agree. One has said top end and another bottom end. If it is top end when I think the consensus would be to get the present engine rebuilt. However, if bottom end then, because of the increased cost, the better option might be to replace with a reconditioned engine.

Santa Fe (CM - 2007-12) :: Intermittent Engine Cranking / Knocking Noise

My 2007 CM Santa Fe 45K miles began acting up intermittently. We have owned it 5 years from new and never any issues whatsoever. My wife told me that first thing in the morning it made a horrible clanking noise and the entire car shuddered so she shut it off. Then it cranked and ran for days normally. The other morning I got in it and cranked it and man, it sounded like rods knocking, pistons slapping the crank, it was awful. Actually it sounded like premature or off time detonation, the engine would not idle and would die.

After a couple more tries the engine cranked and ran smoothly but with increasing idle speed and after two instances of normal cranking but idle increasing ever upward (same morning in sequence of 10 minutes or so of trying) I called AAA and had it carried to the dealer afraid oil pump giving out, timing belt jumped, bad crank / cam sensors, who knows? Oil was changed 5K ago with Hyundai toilet paper filter.

Anyway dealer found a code, something about engine torque excess - who knows - it wasn't causing the horrible cranking idling banging noise... did some ECM/ECU update, and repaired a TSB for the passenger side Airbag seat detector. They kept it over night and still could not make it occur.

My wife is really worried because honestly it sounds like it's going to throw a rod or something *I know it doesn't have them*. It's just a horrible gut wrenching noise. Dealer mechanics could not find anything wrong and they kept it overnight to crank it cold, and when we picked it up today it cranked fine.... She can't trust it anymore.

Santa Fe (CM - 2007-12) :: Loud Tapping / Knocking Noise From Engine

I am getting a loud knocking noise from the engine on my Santa Fe. The car is very low mileage of around 51K and has regular service and oil change.

Not sure what has caused this but there is a loud tapping/knocking noise coming from the engine. Have got it locally checked with the garage and Hyundai Workshop also but both have suggested that Oil levels are appropriate and they need to open engine to investigate more.

At a higher RPM the sound becomes more loud and recognizable.

Santa Fe (CM - 2007-12) :: Intermittent Ticking / Knocking In Rear Of Engine

I have a 2007 2.7L with 150,000 miles. Yesterday while driving at 20mph my engine all of a sudden started knocking like I lost the timing belt which I replaced 10,000 miles back, including the tensioner fully (bought as a kit off Rock auto). I parked immediately. Today we investigated a little more and what we found is that os is more like a loud knock and not a metal on metal sound. It definitely knocks faster or slower with the RPM of the engine. It even ceased for a while and the engine idles silently but then on the next restart it came back.

It even went away again with an increase in RPM but then came back at an idle or sometimes didn't. You can clearly hear it in the rear of the block. I will admit I have never changed the plugs. We can a scan on it and a misfire in #4 cylinder came up. Unfortunately my check engine light is always on because I have a bad sensor in my fuel tank that ill get to some day. So I'm not sure if that code is recent or not. I know I need to identify the location of the sound more closely before anyone touches my motor. Could it be bad gas that causes a misfire and knocking? I have had that code before and new gas fixed the misfire but there was no knocking then. I religiously change my oil every 5000 miles and just did 500 miles ago.

Santa Fe (CM - 2007-12) :: 2008 - Loud Rattle / Knocking Coming From Engine At Idle

Trying to find any information on what's happening with my 2008 2.2 Diesel Santa Fe ... Been driving fine until I pulled up at a set of traffic lights yesterday and started hearing a loud rattle- knocking coming from the engine at idle.

Put it in gear and drove and it goes away. When at idle if you rev the car it goes away.

Mechanic seems to think it could be clutch as it vibrates the gearbox, but sound seems to be more prominent around the engine, my thoughts were maybe a loose timing tensioner.

Clutch replacement is very expensive.

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) :: 2011 3.5L Engine Noise Upon Startup

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.

Santa Fe (CM - 2007-12) :: 2011 3.5L - Whining Sound From Engine

I have a 2011 Santa Fe 3.5L with about 108,000 kms (roughly 65,000 miles) that seems to have produced a bit of a whining sound from the engine. It will do it in park, or in gear, and the sound seems to increase slightly with an increase in RPMs.

Santa Fe (CM - 2007-12) :: 2011 - Water Leaking From Bottom Of The Engine

I just purchased a 2011 LE Santa Fe,(2400 mi) and have a question regarding water leaking from bottom of the engine. I called the dealer and service rep explained it is more than likely from condensation build up on heater coil and being drained through the vent tube. I believe this is normal and have observed on other vehicles I have owned during the summer months when using AC.

I don't believe I have seen this condition in the winter months 40 - 50 F degrees when using just the heater. I'm hoping this isnt systematic of another problem, that was simply explained away by dealer. It sounds logical but then, again, I have never seen it when using the heater. I do leave heater at full blast when I start the car remotely to warm up cabin temp on those cold chilly mornings.

Santa Fe (CM - 2007-12) :: 2011 3.5L Engine Oil Leaking From Rear Main Seal

Newly acquired 2011 Santa Fe GL. Recently had a 2008 Azera GLS.

We received the Santa Fe a week ago and have since put 600 km on her. I took her into my work (auto mechanic) to wash and wax, looked underneath the engine and noticed 2 drops of what appeared to be engine oil. Between the transmission and engine block there are 2 10mm vertical bolts. The drops of oil have accumulated on the head of the bolts. There is a small "plate" between trans and engine with oil "weepage". My guess is the engine rear main seal is leaking! Not a small repair and certainly at 600 km.

Santa Fe (CM - 2007-12) :: Front End Knocking Noise

I have a 2009 AWD Santa Fe with a little over 43K miles. Over the past few months it's developed a knocking noise that is most audible from the front drivers side area. The knocking speeds up or slows according to the car's speed, and appears somewhat louder when the steering wheel is turned. My initial suspicion from my surfing here is either a CV joint or wheel bearing.

I took it to the dealer that sold it to me and am getting increasingly frustrated with their work. The first irritation was yesterday when the service advisor called to say the problem was corroded rear rotors and brake pads; both wear items not covered under warranty. Though skeptical (since I was hearing the noise coming from up front, not from the back) I authorized the $300+ for turning the rotors, replacing brake pads and flushing the brake system.

When I showed up to retrieve the car I was told it'd been test driven and the problem was fixed. I asked the tech specifically whether he'd checked the CV joints and he assured me he had and they were fine. Upon driving away it was immediately obvious the knock was still there. Back to the dealer. I had the tech drive it with me in the passenger seat. He acknowledged he could now heard the knocking, but claimed he previously couldn't hear it over the horrible loud squealing from my rusted rotors; nor had he heard it on his alleged post-fix test drive. The problem with that is I've never heard this claimed horrible loud squealing, nor has my girlfriend, nor have any other regular passengers.

Back at the dealership the situation escalated when the service advisor, in defense of his tech, also claimed the horrible squealing rotors had drowned out any other noises. The problem with that is he admitted he'd not come along on any of the previous claimed test rides, and claimed to have heard the horrible squealing rotors only while the car was in the shop and/or up on the lift while the tech was turning a rear wheel by hand. Err, if the car was not driven any for distance or speed, of course you wouldn't have heard any knocking up front.

Yesterday evening I got a call from the shop advising the problem had now been diagnosed as a bad wheel bearing, front driver's side. I was assured it'd be fixed and ready this afternoon. All well and good. I showed up this afternoon and the service advisor stated the car was just getting buttoned up and we're going to test drive it. Fine, I'd like to come along on the test drive I said. He agreed, asked me to sit in the waiting room. In a few short minutes though - not long enough IMO - he came back out to advise the tech had just test driven the car (without me?!) and the knock is still there.

As of this writing I have no info from them as to what it might be. I left the car with them and asked the service advisor to have the tech(s) double check the CV joints. He got huffy with me and declared that if if the tech said he'd check them, there's no need to do so again. At this point I'm not sure whether I can trust this dealers' service department. I don't think the service advisor is being honest with me - I think he's been caught in a minor fib re: test riding and is compounding the situation by sticking with it.

Santa Fe (CM - 2007-12) :: Knocking Sound When Warming Up The Car

New hybrid battery 20# miles ago; used transaxle 10# miles ago (with 1.5 yrs left on 2 yr warranty); new tires 10 miles ago. Has 185,000 miles.
