Sonata NF (2006-10) :: 2007 - High Pitch Rattle / Engine Vibration Noise

I have a 2007 Sonata, 2.4L 4cyl. and it is making some weird noise as of late. I have done some research and from what I have read it seems like it may be a bad engine mount. One thing to note is that the noise really only happens when the car is cold and hasn't warmed up yet or on a cold day.

Basically the best description is that the noise is a high-pitched rattle/vibration noise. The noise seems to match the vibrations of the engine but doesn't seem to get more intense if I rev the engine. The noise does get quieter if I put it in neutral but it is still there. The noise also happens even if the car is parked and off, and I do something like shut the door or trunk. I haven't gotten a chance to get in there and look under the hood myself to try...

Prius (Gen 2) :: 2006 - Faint Rattle Sound When Engine Under Load?

Today I drove my 2006 G2 Prius with 59,000 miles to the park and had the windows down. I climbed a hill for a good while that had the engine under load and there was a concrete wall beside me, and I could hear a very very faint metallic-like rattle. I mentioned it to my partner who listened and said he couldn't even hear it, so maybe it is just me.

Sonata NF (2006-10) :: Clacking Valves When The Engine Is Under Load / Hard Accelerations

I have a 2006 sonata with a 2.4 . It has 120,000 miles on it right now. Around 100k miles , when the engine is under load(hard accelerations), the top end of the engine starts clacking,like the rockers arms are loose. It also does it when in park and you rev it up above 3000 rpm then let off the gas. I have not had time to pull the valve cover yet.

Sonata NF (2006-10) :: Noise And Rattle When Turning And Accelerating At Same Time

Hit a long 4x4 post on the freeway and bent a front rim. Was able to miss most of it but hit it with the right tires. It didn't hit anything under the car that I can tell. Got a new rim and moved the TPMS and tire to the new rim. Back wheel looks ok. Still have a low pressure light. TPMS was lit when I had the bad wheel out of the car but is now out.

Have previously had trouble with another wheel giving a warning when it was only a pound or two low. Checked all the wheels and added a few pounds to each and still have the light.

How do I troubleshoot the TPMS? How long should the batteries last - is this just normal life of the sensors? It's a 2009 model.

Also have some noise and rattles I didn't have before. Not when going straight but when turning and accelerating at the same time. Hoping its just some shields and nothing too serious... I looked and didn't see anything obviously loose so I need to dig into it a bit more.

Sonata NF (2006-10) :: Metallic Rattle From Engine Compartment When Accelerate From A Stop

2008 Sonata Limited.

When I accelerate from a stop there is a metallic rattling in the engine compartment. My best guess is that it is near the middle and near the firewall. Can't see much under the hood in this area.

The rattling stops after about 60km/h or so and does not happen at all during cruising otherwise.

Sonata NF (2006-10) :: 2009 GLS Dash Rattle / Crackling Noise When Going Over Small Bumps

I bought a 09 Sonata GLS in July, really nice other than dash noise, what has been described as crackle. Briefly, my sonata is makes crackling noise going over small bumps, more pronounced in colder temp. I have taken it in to the dealer 4 times, problem still persist. According to the dealer, Hyundai regional office knows of my problem, and there is no fix for it at this time. I just bought the vehicle and I am suppose to live with it?????

Celica :: 1992 GT Engine Rattle Under Load

I've had this noise on my 92 GT since I bought the car and it hasn't got any worse but I still am wondering what it is in case it's something serious. I hear a rattle/clatter coming from the engine or thereabouts, and it only happens under load (doesn't have to be heavy load, but I can't hear it in neutral or when the clutch is disengaged). It only happens above around 3000 rpm and the frequency of the rattle corresponds to the engine rpm. It's difficult to pinpoint the location of it because it only happens under load. Anyway, I made a short video of it and uploaded it to YouTube....

Accord :: Throttle Body Vibration - High Frequency Rattle Noise Inside Engine Compartment

So I'm at my wits end trying to locate (and fix) a loud, high frequency rattle noise inside the engine compartment.

It can be heard when applying the gas pedal a certain amount. In other words, I can "find" the noise and maintain it at a certain rpm.

The noise is coming from the back of the engine near the firewall. It feels and sounds like it's coming from the throttle body plate and vibrating the gas pedal. I cleaned the plate and it isn't loose.

The issue doesn't seem to be affecting engine performance.

The sound is noticeable while driving (under load). When in park, I can find an rpm where the throttle body seems to take a heavy wave of vibration from the engine and hum (but not nearly as loud as while driving). Issue existed before I put on new motor mounts, and still persists after replacing all 4 (although the vibration and noise are reduced).

Lexus IS 2014+ :: Rattle / High Pitch Noise When Engine Running In 3500 - 4500 RPM Range

I've noticed a noise coming from my car (2014 IS350 RWD) that sounds like a light, irregular rattle, when the engine is running in the 3500 - 4500 RPM range. I don't hear it necessarily under load, but if I am in manual mode in a lower gear, and let off the throttle, I can hear it.

The best way I can describe the noise is like a bowl of rice crispies (rapid and random), only slightly louder. You have to listen for it, the road/traffic should be quiet, and if you get back on the gas, the intake noise that's plumbed into the cabin pretty much covers it up. I can also hear it in Park or Neutral.... I've wondered if it's a loose heat shield, or an exhaust issue, but I can't hear it standing next to the car or with my head under the hood. I only hear it from the cabin. The rhythm of the noise is irregular.

I don't think it's ping/detonation, since that usually shows up under load, is much louder and has a decidedly metallic sound to it compared to what I'm hearing.

Sonata NF (2006-10) :: High Pitched Whining Noise While Driving The Car

After it has been sitting overnight, I hear a somewhat high pitched whine while driving the car. It seems to go away after the car warms up a bit (maybe I can't hear it). Here are a few other details

a. 2006 Sonata 3.3 V6, ~85K miles on the odo

b. Transmission fluid flushed at Valvoline ~2 weeks ago. I changed it at 39K miles when I bought it. Checked at 78k miles and the color was was good (light red).

c. The noise goes up and down with engine rpm. I have a sound (wav) recording of it, but cannot figure how to attach it.

d. I tried putting it in park and neutral and revving the cold engine, but cannot hear the whine-only happens in drive.

e. Engine oil changed every 3-5k (wife drives it, so I'm not always prompt).

It shifts smoothly (always has) and otherwise drives well.

Sonata NF (2006-10) :: High Rpm Cold Start / Engine Is Knocking

Recently, our 2009 Sonata jumps to relatively high and not normal RPM when start cold (and I don't mean winter-cold; I mean first start in the morning). It jumps to around 2500 rpm for 3-4 seconds before it goes down to the normal 1200-1300 or so for a cold start.

Also, not sure if this is the normal Sonata engine sound, but when we push the accelerator it sounds like the engine is knocking, almost like a whistle of fuel flowing.

Ford F-150 (2004-2008) :: Funny Rattle Noise Under Load When Going Up A Hill

I bought a 2004 F150 XLT 4x4 122,000KM. I used to have a 1995 BMW 318TI but I built a cabin and a truck seems to go with it. I have already done some work like new plugs, oil change, tranny flush, fuel filter change and Air Filter. I noticed about 2 weeks ago going up to the cabin a rattle sound when I was going up a hill. It is coming from the right side (FRONT) and it sounds like its from the wheel. I really does it if I give it some gas and then press a bit more on the peddle and then you here like marbles in a tin can if that makes sense. I just got back from my mechanic and we took it out and it is still doing it so we jacked it up and checked everything. Their are no loose clips and back plates making noise. We did notice that a heat shield near the cat was rubbing and we adjusted it, this did not solve out problem. We were both looking at each other after an hour wondering what the hell this could be. I am going back on Wed and he is going to hook it up with some kind of machine with microphones and a headset to pinpoint the problem. It does not affect the performance of the truck but it is very annoying when I need to give it some gas to pass or go up a big hill.

Accent RB (2012+) :: Rattle Ping When Engine Is Under Load (accelerating Hard Or Uphill)

We've got a 2012 Hyundai Accent GDI. I've been hearing the rattle "ping" when the engine is under load (accelerating hard or uphill). I've read that this is typical for these engines.

I took it to our local Hyundai dealership since it's still under the 60,000 mile warranty. They updated the computer settings and I put in a fuel additive to clean up deposits. They also told me to buy name brand gas from here on out (Exxon, Shell, Mobil) as these engines don't handle cheap gas well.

Now that I've given you enough of a backstory, here are my questions:

- For those that have experienced the rattle "ping", what did you find fixed the problem?
- Any tips or things to look out for when cleaning the throttle body etc?

Sonata NF (2006-10) :: Jerking Stops When Transmission Is Under Load

My 2006 Sonata has 63K miles and today started jerking (Hunting) after about 10 miles. Here is what I know. It starts on a level run and disappears when on an incline, but as soon as the crest is reached, and on the downside, it starts hunting again. When it is jerking, around 55 to 60 mph, I switch the transmission lever to Autostick and it stops, back into drive again and it starts again. This is so repeatable there has to be a connection. EVERY time I switch to Autostick the jerking stops, end when I put it back into drive, it starts again. The jerking is severe enough that it is easily detectable. It appears that when the transmission is under load, like going uphill, the jerking stops.
