Santa Fe (CM - 2007-12) :: Knock From Engine That Would Go Away When Warmed Up
Nov 30, 2011
With about 32K miles, I started getting a knock in the morning that would go away when warmed up. When I took the car in for service, I mentioned it and the service adviser said, it sounds like the timing chain tensioner leaking down, we have seen that.
Well it was not the tensioners, I was informed that, it was low oil pressure that did NOT trigger the oil light or any warnings, and my main bearings and a rod bearing were shot, it seems that the oil pump was not putting out as it should. Supposedly, it was only putting out 10 PSI. Oddly enough once the engine warmed up, there was no lifter/tappet noise that would indicate low oil pressure that I have experienced in the past with other engines.
The oil has been changed on time, the oil was clean, and the engine was not abused. Other than this the car ran fine. So the short block was replaced under warranty. This is a 3.5 V6.
This is quite disturbing, that some type of low oil pressure message or idiot light was not flashing on my dash. I have seen oil pumps from other manufacturers produce low oil pressure if the pressure relieve valve was stuck open.

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?

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.

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.

I have a 2007 SantaFe Limited with 40k miles on it, first thing in the morning when I start it up there is what I can describe as an valve or lifter knock and it continues until the engine gets warm then all is fine. Oil and filters have been changed on a regular schedule,,,,,is this normal??

OK--2001.5 1.8t Tip, 85k, nothing but Mobil1 since day one religiously. At around 81k miles the t/belt tensioner seized & let the belt jump and bend a few valves. Had VW do the repair under the p.t. warranty. Engine now runs very well again except there is a knock noise that sounds an awful lot like a crank or rod bearing. The noise is worse with the engine fully warmed up and in drive or reverse. Took it back to VW, they said it's a bearing in the a/c compressor. Sounded like B.S. to me, since the noise is no different with or without the a/c on. I picked up the car & removed the a/c belt at home & found the noise was exactly the same. I've about had it with VW on this issue. Been back 3 times with the noise complaint, & the noise is getting worse!!

I know this issue has been posted and discussed multiple times on early Gen 3 Prius'. That said, I don't see much on it regarding the Prius v ( lowercase v for the Prius v wagon, not an uppercase ). There is also of course a TSB for earlier Prius' that had the issue.
I can readily replicate the issue in that almost every time I 'think' it may happen the next time I start the vehicle, it does in fact do so.
If I move the vehicle from the garage to the driveway or around in the driveway to clear snow, the ICE fires for a few seconds then I shut it off as the car is where I need it. Upon the next ICE start, there is a horrible knocking under the hood somewhere. Different from the previous messages and the TSB itself is that I never get an error code or MIL.
I'm to the point where if I move the car, I let it warm up completely. I figure I'm better off wasting fuel than subjecting my Prius to whatever horrible thing is happening under the hood if I don't.

3.5 has engine knock coming from oil pan, gets louder when engine fully warmed up. Suspect connecting rod bearings. 99 Intrigue has 203K on it and otherwise in excellant condition. Is it possible to replace connecting rod bearings with engine in car. What is involved in removing lower crankcase after oil pan is removed. Car has been trouble free so far and would like to get another 60K out of it

This is probably always present but I hear it most at low speed if I am off the gas and brake. Slightly accelerating or lightly touching the brakes seems to reduce or stop the noise. It is a knocking noise coming from the right front and the rate is related to car speed. I am guessing CV joint. What is it?

I just bought this truck yesterday. During the test drive and everything it seemed all fine. After all the paperwork and the truck was actually mine. I noticed once it is all warmed up it seems to have a slight knock/tick? and a slight miss to it. I shot a couple videos, one up underneath where it sounds like most of the noise is coming from. Could it be an exhaust leak? Or is it something internal? Like the Cam Phasers, or a rod or something!
Here is a video around the exhaust area.
Here is up underneath the truck.

Over the past few week my truck has developed a knock once it has fully warmed up. At first I thought it was possibly injector knock and kind of got excited about the prospect of upgrading to larger injectors. Well, my short lived optimism came to an end today once I got ahold of my father's mechanics stethoscope. So today I let it fully warm up and like clock work the knock came back. After going over nearly every inch of the top end, nothing was producing what I was hearing.
So I crawled under the beast and located the source. Right where the bellhousing mates the the engine block is where the knock is definitely loudest. At first I thought it was louder in while in gear but today it didn't matter if it was in gear or not. I removed the bellhousing cover and inspected what I could see of the flexplate. Couldn't see and cracks or breaks but from what I see through google searches is that it cracks behind the spacer. Now my first thought is that it's the flexplate but I'm hoping more experienced people can tell me what they think.

I have a 2007 Camry XLE with 30,000 miles on it purchased new.I stated it up the other day after setting all night it had a very loud knock in the engine I shut it off and had it towed to the dealership. They started it up and wanted to know what happened they said it sounded like a rod out. They keep it several days and ended up doing a top engine flush and then replaced the spark plugs. They said it was a carbon build up.I asked if they suggest any thing to keep this from happening and they said they do not recommend using any thing. I thought carbon deposits were supposed to be a thing of the past. Does this still happen.

Did oil changes myself every 5k full synthetic. when the car developed a knock i noticed the engine oil was scary low. Since i got my car from the time i got it at 19k and i bought the 7/100,000 mile warranty on top of that.

I recently bought a 2011 460 L, CPO with 28,350 miles. I love the looks and how it drives, smooth! But I do have a concern. Before I go to the dealer I thought I would educate myself from the experienced LS owners. I am hearing a very brief (1-2 seconds) mild engine knock at a cold startup.
This only occurs when the engine is cold and has sat overnight. It never happens after this first startup, even after turning the engine off and then on again. It kinda sounds like the oil isn't getting where it should be for a few seconds. Engine sounds great with normal and hard acceleration throughout the day. The dealership where I bought it is 300 miles away, so I would be taking it to a local dealership.
Now I did hear this noise and mentioned it to the service manager when I first bought the car, and the service manager told me that this cold startup sound is normal. He also mentioned the direct injectors at idle. I guess sometimes it's hard to fully trust what dealerships say. Is he right?

So my wifes 07 93k miles started to make a strange knock rattle noise. It sounds like the knock some on here have when the water pump was going out. It only happens when the car is on, in gear ( drive or reverse) brake pressed And AC ON. The engine begins to vibrate under the load and the rattle begins. Sounds like you its coming from behind the alternator under the valve cover. Once I place it park.... or turn the AC off it goes away. It idles fine. Quiet And Smooth. But once I place it year it comes back!!

I am after to find which USB cable and software can be used on my wife's ... 5/05 v6 Santa Fe to check the error codes. The car is revving up and down when cold and lacking power when warmed up, I'm guessing it's a sensor but I need to find which one.

Recently started experiencing a hard downshift after driving for 30 minutes, and only from 2nd to 1st. No other shift issues with other gears, up or down.
When moving over to manual shifting, it doesn't appear to have the issue when downshifting in manual.
I replaced the radiator about 2 weeks ago due to a serious leak, and the shifting problem wasn't an issue before as I would have noticed.
Going to start with the fluid lvl, but it feels odds with it occurring during the downshift to 1st.

I bought the car 3 years ago 2003 2.4L Hyundai Santa fe , I have driven it around 200 miles ( to and from shops ), I am having an issue now where once the car is warmed up ( post 15 mins ) It will idle really low * almost stalling * and oil pressure light will flicker, If I hold the brake and get it to almost 800 - 1k RPM it goes off and driving is not an issue *no knock*. I just got it driving for the 1st time in the past year, and drove it for about 45 mins in stop an go traffic, Temp light was all the way to cold, once stopped in stop and go traffic it would go up half way, as soon as I could get above 50mph it would slowly work itself all the way to the bottom?

My 2005 Santa fe has a single knock when you press the accelerator, then between 60 and 70mph there is now a shake in the steering wheel. I have been told it is probably the CV joint and just wanted more input.
