Santa Fe (CM - 2007-12) :: Intermittent Engine Cranking / Knocking Noise
Nov 1, 2012
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.

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.

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.

Three times in the past 2 weeks my Santa Fe wouldn't start. Never first thing in the morning but after the car is warmed up. I have stopped for gas/run into a store for 10 minutes. When I get back and turn the key I get electrical power (radio and fan etc.) but no cranking or engine turnover. It happened on a rainy day and twice when it was very hot and humid so maybe the electronic components are faulty.
After 10 or 15 minutes the car will start as if nothing is wrong and then I'll go for several days without any problem. I've tried both keys and I tried moving the second key around the steering wheel - in case the engine immobilizer is having trouble reading the key.
I have had the car since April 2, 2007 and I put only 3500 kms on it. It's a GLS 3.3L 7 passenger. I've read that it could be the crank position sensor.

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.

My new SANTA FE has merely covered 10000 km. The vehicle is running fine except a very irritating loud knocking noise from top of front windshield area. The noise is generated as soon as vehicle goes over a minor irregularity on road or even if you make a sharp right or left turn.

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.

My car has less than 500 miles on it. Yesterday when I started it, I heard a knocking sound. I only put 87 octane gas in the car as the manual said 87 or higher. I don't know if I made a mistake putting 87 in there.

I have a 2007 Santa Fe 3.3. We bought it used with 24k on it about 5 1/2 years ago. I've uploaded a zipped mp4 of the sound that comes from the area of the AC. The sound was recorded from the passenger seat as it never seems to do it when I'm ready with the hood up.
So far the car has had 4 compressors in 72k miles. The first burnt out the clutch, as did the second a year later. This noise is intermittent, but is getting more frequent and worse. The noise started about a year ago, 3 years after the 3rd compressor install, the compressor was changed out but the noise came back 2 days later so I'm guessing it wasn't that. It only happens when the AC is engaged and doesn't change with the speed of the fan. I'm more concerned as the extended warranty is coming to an end, 75k, and the mechanics really seem stumped.
For those without audio it's a really hard noise to describe. It starts of with almost a low thump and then turns into a resonating metallic screeching. If I turn off the fan or the AC, the noise stops and I can turn them back on a few seconds later and it all sounds normal for a while.

When I drive my 2010 santa fe. I get a noise that sounds like i have a flat tire in the back. It is intermittent and starts at any speeds. But when you stop the vehicle and start again the noise is gone. The mechanics at Hyundai replace replace a part for the all wheel drive but that did not fix the problem.

I have a 2010 Santa Fe V6 2WD. When I rock my steering wheel back and forth, I hear a knocking sound when engine is off. Sounds like maybe the steering gear box has play in it.

I have a 2008 petrol Santa Fe with an automatic transmission. Recently the transmission started to intermittently make a noise like a buzz. The noise most commonly occurs when first moving off in D or R and always stops when the transmission is put in Park.

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.

2004 Santa Fe, 2.7 L V6. The oil was changed approx 5-7k miles ago (not really sure as I bought it from someone else) and I just changed it today. There's a new knocking noise in the engine. I used normal castrol GTX oil, 5w-30.
I drove it about 20 miles and the noise is still being made, so it's not a circulation problem.

For the past year I have had intermittent start issues with my LS that occur about 15 percent of the time. Ambient or engine temperature do not make a difference. Sometimes the starter engages but then disengages right away. I then need to depress the start button an additional time or two before it actually starts. At other times the starter engages and continues cranking while the engine sounds like it is trying to start (like it is just barely keeping ahead of the starter speed). That carries on for several seconds and then it starts. Nothing shows on diagnostics and the dealer says I am going to have to wait until there is a complete "no start" before they can trouble shoot. There was a similar issue with earlier 460 models but the Lexus service tech said that problem does not apply to the 2011's. It seems there is a lack of fuel delivery but from what point? And why only intermittent and momentary?

I am trying to diagnose and engine knock I think. 2007 Honda Ridgeline 3.5 Liter. 257,000 mile. I checked the noise unplugging each coil pack with no change. I ran it without Serpentine belt no change. Here is a link to a video I made with the noise. Best at 30 second mark. [URL] .....

my friends Hyundai Santa-FE 2007 makes a knocking noise like a hammer hitting the engine when she starts the car and drives. What could that be?

I am having this issue if it's one. With the fuel level below last quarter, I'm having the time of starting the engine longer (cranking time). I tried several times, leaving the fuel level reach the last quarter, with same result. Reaching that level of fuel the problem appears.
Another issue is that sometimes when the day is hot and the fuel level is not necessary below quarter, the starting time is longer too. It's a Santa Fe AWD 2.4L Automatic.

My '08 2.7 has difficulty starting in the morning. It makes the normal cranking noises but won't fire up immediately. I typically let it try to catch for 5-10 seconds, pause, and try again. Then I wait a minute, try again, and everything starts fine. Then it'll start normally the rest of the day.
Pardon my ignorance, but isn't there some sort of compartment that holds fuel into the engine with a check valve that keeps it from releasing back into the tank? Could it be that this valve is leaking?
Or does it sound like I need a whole new fuel pump? I tried to find schematics, but had no luck. I tired hmaservice.com, but I'm not willing to install the Adobe SVG app (obsolete and security risk) to view the documents.
