Sonata NF (2006-10) :: Rattle Comes On Any Random Time
Oct 15, 2013
I've bought 2006 gl sonata 2.4. Car sounds good though rattle noise comes on and go of any time. I can drive my car for an hour and never hear anything, or i can just start the engine and hear the rattle. The noise is the same all the time though it could be louder or more silent randomly. My AC doesn't work. One friend of me said it must be AC compressor that starts and stops by itself because of the some magnet in it. Could that be true or there is a different reason?

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.

It's happened twice I am sitting at a light then the ESC and ABS light pop on. When I turn off the car they go off and it hasn't happened again.

My car has had random misfiring when at idle and has been shaking really bad but once I accelerate and get up to speed the vibrations and misfiring stop but the check engine light flashes for a few minutes. I have changed spark plugs, all 6 ignition coils the intake manifold gasket and both camshaft position sensors. My car has 180K the codes that are showing up are 300,301,303 and 0016. I really love the car and have had no prior issues the car before this ran like a champ.

Lately I've been noticing an Intermittent/random steering wheel whine. It happens rarely, but as of late I heard it a couple times. I checked the fluid and its topped off. Car has about 85k on it. I'm not sure when it was last replaced.
I'm thinking My next step would be changing the fluid. What is the actual procedure for doing this? Also, if I do go ahead and change the fluid and still get a whine here and there. What would be my next step?

I know it is a random cylinder misfire code however I started my car in the morning and it was fine I moved it and put it back in my driveway. I started it up later and waited for it to heat up i came back outside 10 min later and my check engine light was flashing and my car was shaking like crazy you could tell the engine was misfiring like crazy. I had under a quarter of a tank but not empty yet. I shut it off and turned it back on and it was still doing it. I drove the mile to the gas station the way it was.
Under partial throttle it was revving to 4500 and over 5, had to let of throttle to make the car shift up a gear. I filled up and started the car again performed fine after that however the check engine light was solid now and still on. I went to my local mechanic and he read that code P0300. I changed my spark plugs that day and they were crap the original spark plugs I have 65,xxx on my car now. Car is smooth now. I cleared check engine when i saw him first and it did not come back on all day even before i changed the spark plugs later that night. Why my light was flashing and why my car was acting like that till i filled up?

Ever since I purchased my 2009 Sonata Limited, it has had a rattle in the rear end some place. Hyundai replaced brake pads, calipers, shocks, etc and checked sway bar but rattle still there. It is especially noticeable in below freezing temperatures.

When my 2006 Sonata 3.3 goes faster than 40 mph, a rattling noise develops under the hood. There is no sound when the car isn't moving. The dealer cannot locate or fix the problem.

I own a 2012 Camry Hybrid XLE, but I'd imagine this issue could exist w/ any trim. Hear a slight crinkle/rattle from time to time coming from your headliner area? At times it almost sounds like someone padded your headliner with a plastic grocery bag.
I usually heard it on bumpy roads. I went through a nightmare with my dealer where they had my car for about 40 days trying to figure out the cause. They even replaced the headliner! (they did a lousy job too, w/ lots of oil smudges and scratches on my plastics)
Discovered the real cause of rattle. The sound actually comes from where the sun visor meets the headliner. The white plastic socket (pictured) where the sun visor plugs in has some wiggle room. When the car vibrates (be it from a bumpy road or what have you) it can slide against the interior cut out of the headliner. This makes an obnoxious crinkling sound.
At the moment I'm driving around with no sun visor on the passenger side-- and I also have no rattle (occasionally I might hear it from the driver side sun visor, but it's minor). I'll probably add some foam up there to add some more tension to alleviate the issue completely. Even just re-seating the sun visor and ensuring the screws are tight would probably have significant impact...

I am asking this question for a friend of mine that lives about 2 hours away from me. She is having trouble with her brakes squeaking all the time. She just had new pads put on the car about 2 years ago. She stopped by a brake shop and they said the pads are good but the rotors have something on them which is making the squeak. I told her the rotors could be turned down to remote the varnish but she said the guy told her the rotors could not be turned down. Since she has moved since she had the new pads installed there is no way to get them to do it correctly. How to make the brakes stop squeaking short of changing the rotors.

I have a strange rattle from the center vent. This happens only at idle when at light or stop sign. If I move shift to N the rattle stops. This happens after car is warmed up to operating temp. seems like maybe the idle is a bit low. I have 35k miles.

I have a '07 Sonata GLS with the 2.4-liter Theta engine and the 4-speed automatic. It has 52k miles on it and has always been serviced regularly. It's been a pretty decent car but is starting to feel a little tired, most notably the worn/bouncy suspension.
Anyway, the other day I was driving down the highway and gave it a little gas to pass a slower car. Doing 60 MPH it downshifted to 3rd (~2000 to ~3300 RPM) and I thought I heard a noise in the engine bay, but I wasn't sure. I ended up needing more power so put it to the floor and as it kicked down to 2nd at ~5000 RPM the rattly noise got a lot more pronounced. Driving around normally I don't hear it but any time I put it to the floor (merging/passing) I will hear the rattle. I can also hear it if I lock it in 2nd gear and give it full throttle up a hill at low speed, like you might do with a stick shift.
It seems like it only does it under load because if I rev it to ~4000 RPM in park in the driveway, there's no noise, even at full throttle. I know the V6s had tensioner issues but I haven't heard much about the 2.4s. I'm not super concerned as it is still under warranty but what might be wrong with it as this is my first Hyundai vehicle, especially in case the dealer can't replicate it.

Rattling noise in the belt area of the engine...

Two months ago I bought a used 2006 Sonata v6 with 54,000 miles. After a few hundred miles I began to hear a rattle on cold start that lasts approx 5 secs. I did my research and saw the TSB concerning the timing chain tensioners. The TSB instructs the dealer to turn the engine off after reaching operating temp then restart after 10 minutes. If there was no noise after the ten minute start then the car is operating normally. My car does not rattle after the 10 minute start up. I just can't see this as a normal characteristic. What could be causing this noise?

2008 Sonata 2.4L ... I have an issue, hopefully minor, but when I drive over bumps I hear a slight rattle in the front suspension. My first guesses are either a sway bar, struts, or tie-rods.
My second issue is the steering wheel isn't centered. Best way to describe it is if you draw a line dead center on the top of the wheel and remember that spot, when driving straight it's about an inch or two to the right.

My daughter has been learning how to drive on our 2010 Sonata GLS, which stands at about 108k miles. We've done threshold braking, ABS activation, some higher lateral force slalom-type stuff, etc. Suffice it to say that we haven't gone really easy on the car.
Now, there is a squeak that began at first at low speeds turning left. The squeak seems to be about one wheel revolution or so (speeds up when our speed increases, slows when the car slows).
After 30-60 minutes of driving around town (city driving and some rural), the squeak happens even when driving straight ahead. We haven't had any suspension work done on this car. I replaced the rotors and pads on all four corners last summer (and bled the lines).
What are the most probable causes of this (and what are the fixes), so I can start tracking it down.

Random issue that has progressively been getting worse. I'm assuming it's one of those Sonata quirks that we all deal with.
When you turn the key the starter doesn't try to crank the engine. AC stuff all works properly. I just keep turning and eventually it will turn on.

I have a 2006 Sonata GLS with the 3.3L V6 and close to 230,000 miles. A few months ago I noticed that my crank time at starting was longer than typically - it has steadily gotten worse.
Now the crank time is close to 8 - 10 seconds. (Which might not seem like much but trust me, it is).
I suspected that the fuel pump was faulty, however, once started - it runs great.
I put a pressure gauge on the fuel pump outlet and found that it only kicks the pump on when the car is cranking, the fuel pump does not kick on when the key is in the "on" position. Once the vehicle starts, it seems to be drawing fuel.
The pump has all sorts of pressure, I am not worried about that.
I decided to change the Fuel pressure regulator valve thinking that maybe it wasn't holding pressure - That didn't seem to do anything.
Do I need to change the entire Fuel Pump Assembly?

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.

Yesterday i went to mechanic and changed Timing chain tensioners, with chains and all guides. But still have 2 second voice on startup, once oil pressure lights off everything fine. I paid heavy price on parts and labour but very disappointed after hear same noise again today morning which i was listening from one year purchase of this car... Sonata 3.3l v6 ....

My 2006 2.4l Sonata automatic has just past the 100000km mark and developed a rattle on start-up. Opened it up and the chain has stretched beyond limit of the tensioner and has destroyed the adjacent oil spray nozzle that sprays oil on the sprocket.
This should be a lifetime item? No abnormal usage, normal city driving, all services done, never run low on oil-strange or not. Why this has happened.
