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.

Ford - Explorer :: 2002 - Ticking / Knocking Only After Warm Towards Rear Of Engine?

I have 02 Limited 4.6 with 128k and upon startup there's no noise (sometimes misfire, due to oil in plug wells, gonna change the intake mani and coils soon). Shortly after it warms up - 5 minutes or so there is a constant ticking at idle...I can't really tell if its there upon acceleration as I can't notice it with the window open when I'm driving, but as soon as I slow down and/or idle I hear it again.

If I let the car sit for a few hours, or while I'm at work, it starts up perfectly fine, no noise.

I tried the long screw driver trick - putting it to different parts of the engine and placing my ear over the handle, and didn't really notice anything different from any part of the engine. I had it up on my lift, and it almost sounded like it was coming from the rear - near the tranny, but what the hell would tick back there? and how do I diagnose that?

I dropped the oil pan when I first got it and there was a very little amount of black rubbery stuff - presuming its timing chain guide/tensioner related, but no chunks, not really any metallic shimmer in the oil, so I guess it could be that, I'm gonna pop the valve cover off and inspect - but like I said, didn't notice anything with the screwdriver trick....I'm at a loss

Camry :: 2007 V6 - Ticking / Knocking Sound When Engine Is Cold

When the engine of my 2007 Camry LE V6 is cold, it makes a ticking/knocking sound. The engine has 100,000 kms on it (60k miles). The frequency of the sound varies with the speed of the engine, not with the speed of the car.

When engine is cold: The sound happens roughly twice a second when the engine idles (at 700-800 rpm).

When engine is warm: The noise is less audible. It can be heard when idled at a stop, but you have to listen for it. The noise cannot be heard on the highway.

The car doesn't burn oil, and the oil level is ok. I had the oil changed 3000 kms ago, and it is still very clean (clear). The was the same before and after the oil change.

I am wondering if it could be the lifters, bad plug, or maybe a timing issue.

Santa Fe (CM - 2007-12) :: 2009 - Ticking Noise In Engine When Warmed Up

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) :: 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) :: 2011 - Engine Knocking When Starting

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.

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) :: 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 SM (2001-06) :: Intermittent Ticking Sound Coming From Glove Compartment Area

For the last two days I've had a very intermittent (tck, tck, tck) sound coming from what sounds like the glove compartment area. It has a rep rate of around three times a second and is very regular. It sounds like a relay to me. It has only lasted less than 20 seconds on each occurrence so don't have time to troubleshoot. I took that area apart and I see two 12volt 25 amp what look like relays just to the right of the glove compartment. I've left that area torn apart so if it happens again I can feel the relays and get it down to one-and or eliminate them as the cause of the noise.

Lexus RX 2010-15 :: RX350 Engine Ticking / Knocking And Rattling On Cold Start

I just purchased a 2010 RX 350, has only 7k miles on it. Really, really nice car. I noticed for the first time yesterday the engine ticking/knocking/rattling/whatever you want to call it sound when starting up on a cold start. It definitely goes away after about 5-10 minutes of running.

Most people seem to accept this as "normal". They hear it, live with it, and they never have any problems. I am a new Lexus owner, so I have trouble digesting that such a luxury vehicle with so few miles would have a "normal" engine knocking sound at 7,000 miles.

A few people posted in other places that this is indeed an issue, and should not be happening. There is a a Toyota (Lexus) service bulletin that I didn't get the details on, it is LSB-0028-09. LEXUS: ENGINE TICKING NOISE AND/OR MIL ON P0014, P0015, P0024, P0025, P0017, OR P0018. ENGINE MECHANICAL. *PE

Looking for details on this service bulletin, and if it does indeed apply to the engine knocking sound.

- Premium gas
- High viscosity cold synthetic oil
- Dealer fixes issue
- Other fix?

Sonata NF (2006-10) :: Slight Knocking / Ticking Noise Coming Around Engine Area

It's a 2006 hyundai sonata LX.

Now Is it anything I should worry about? Car has 72000 on it. Always used synthetic Mobil 1 5w 30.

This is on a completely cold start up, 30 degrees outside. Only makes the noise until car warms up. Anything I can do to prevent this? Or is it not something to worry about? Should I just let the car warm up a little before I drive it?

Toyota - Tacoma :: 2001 - Engine Makes Knocking / Ticking Noise In Cold Weather

I have a 2001 Toyota Tacoma that has a knock or ticking in cold weather. The problem starts sometimes immediately after I start and other times it is only when I press on the gas in the cold mornings after a few min warm up. The noise goes away after 10 min. The question I am wondering is this:

1: could it be worn piston rings and the pistons are slapping the cylinder wall
2: is it an oil pump problem or a oil restriction issue
3: is it a valve guide issue
4: with the history of the 2.7 having exhaust manifold issues (poor manufacturing) could a cracked manifold be the issue

I change the oil myself, the oil filters have been OEM toyota, the noise has been going on since 60,000 miles, the truck is at 230,000 miles.

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) :: Ticking Noise In Sync With RPMs?

I pulled out into traffic and let the RPM's get up there (6500 rpm's) and now I've seemed to have developed a weird ticking sound that is in sync with my rpm's. What could I have popped/broken? Rocker arm? I have the SUV sitting in the driveway and it makes the ticking sound whose interval increases as the rpm's increase...?

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

Bought a 2011 Santa Fe in May. When I'm warming up the car, there is a banging or knocking sound coming from the passenger side wheel area (I think). The colder the outside temp, the louder the sound.

Ford F-150 - 1997-2003 :: 2000 5.4L - Intermittent Engine Knocking Underneath

The knocking started very suddenly 2 days ago - but not after any unusual events, other work etc. Truck has 145 K, and otherwise starts & runs perfectly. Doesn't use oil.

I heard it from in the cab, windows closed. At first, thought it may be a rod bearing - but if so, not terribly loud. Didn't drive it any more after getting home. But starting it in the drive, the knocking was audible.

Then I discovered it * completely disappeared * several times, after shutting off engine, then restart a few seconds later. When that happens, absolutely no knocking at idle or reeving it up a bit. But it may return on the next 1 or 2 restarts, then disappear again.

Since the knocking * completely stopped * on some restarts, does that rule out a bad rod or main bearing?

I haven't seen oil gauge pressure fluctuation, whether it's knocking or not. The gauge is where it's always been - well above 1/2 way. But, the gauge also doesn't move when I rev it to around 2000 RPM (? may be normal not to move, after engine's already running?). When the knocking is happening, increasing RPMs also increases the knocking frequency.

Can't hear the knocking from top side of engine w/ hood open - even using rubber hose to my ear & moving it around. But (when) it knocks, can easily hear it inside the cab or under the truck.

From underneath, knocking is more in the center of truck, near the back of block / oil pan or tranny bell housing. I can't isolate the noise as more on one side of the block than the other.

Could the oil pump itself be making a knocking noise? The knocking is "similar to" a rod knocking, but doesn't seem quite as "hammer on metal" metallic.

There are no DTCs showing on my scanner. Only odd thing was, for "O2 Monitor Test," it showed "vehicle did not return data for any O2 monitor test." Though under the scanner "I/M Monitors," it shows O2 Sens Mon. "OK," and O2 Sens Htr "OK."

Santa Fe (CM - 2007-12) :: Ticking Noise That Slows After Vehicle Is Turned Off

I recently purchased a 2012 used Santa Fe. I've only had it about 2 weeks and just noticed something the other day. When I shut the vehicle off and exit, I hear a very low ticking noise coming from behind the front grill vents. It lasts for about 15 seconds and slows down until it stops completely.

I'll be the first to tell you that I know absolutely NOTHING when I comes to cars (other than how to drive one ). My guess would be that it sounds like some type of fan coming to a stop. If this is the case, I'm wondering if one of the blades could be bent, and how potentially serious of an issue this might be? Other than that, it drives great, with no other notable noises while in motion.
