Sonata NF (2006-10) :: Knocking / Creaking Sound Only In Hot Weather
Sep 4, 2015
I have a 2009 Sonata Limited (4 cyl), and since the beginning of the summer, I have had a knocking/creaking type sound coming from both the front AND back of the car, which feels like is coming from underneath. I can feel it in the floor when it gets really hot, and therefore really bad. I hear it almost exclusively while accelerating or coming to a complete stop. When it gets really hot out, I can hear it very slightly while driving at slower speeds, but that's about it. Has no correlation to making turns, as would be the case with a tie rod.
I find it extremely strange that this is happening only in the heat. When it's cooler out, say below 80-85 degrees, there is no sound whatsoever. The car runs phenomenally otherwise, very quiet. Based on some stuff I've read, it seems like a suspension issue is a possibility? I live in a neighborhood with extremely poor roads, and actually live on a dirt road.

2006 Sonata 2.4 GLS. My car has done 60000 miles and has developed a creaking/knocking (metal on metal clunk) sound at the left rear. it is only noticeable at low speeds when accelerating and decelerating in stop start traffic.
It is not the shock as I have removed the shock and driven the car and the noise is still there, I have also looked at all the bushes and nothing is obvious. I have also checked tightness of all bolts/nuts.

Just replaced the front struts last week and the upper control arms this morning. After putting everything back together I drove her around the block and noticed a horrible popping and squeaking like something was loose. I quickly limped her home and double checked that everything went back on properly and was tight. Car is the V6 with eibach's and about 103,000 miles I have drain and filled the tranny every 30-40k.
What this sound might be? It goes away once I am above about 10-15 mph and sounds like it is coming from the center underside of the car. I will also try to get a video of the sound while I am driving.

I have pushed the back windshield, and haven't gotten a peep anywhere, so it's not that. It's coming from the outside, because it is so much louder driving slower with the windows down. It appears to be coming from the rear left of the car. It's a definite "creak," and not a "thunk." Sounds like creepy stairs being walked over repeatedly...I haven't investigated hard enough to really pin point the direct spot, but it would sound to me like it has something to do with the suspension in the back left. However, it's not any more prominent when I hit a bump than it is just accelerating or decelerating, so that also leads me away from it being a suspension issue. I know I should look further into it to locate the spot.

I have a 2007 sonata 2.4L with 93k miles that has a knocking sounds coming from the bottom of the engine. It seems that it is a bad rod bearing and was caused by low oil levels. I did not know that the oil was that low (3 quarts low) It started about a week ago. I know I'm gonna have to put it on jack stands and drop the oil pan.
By the way, Here is a video I found and it sounds similar to my car. Here's the link : 2.4L Theta Engine Noise - YouTube

2005(its NF model) Sonata 2.4 petrol manual. 75000 miles. On cold start makes knocking sound( sound like Diesel). After coupe of minutes when warms up the knocking sound gone.
Also when i start driving( still on cold engine) i hear that sound only when i let go from gas pedal and only in range of 1800-1500 rpm. When i accelerate i don't hear that knocking sound.
I think is not belt tensioner because sound is much longer than couple of sec.

I own a 07 Hyundai Sonata Limited with 31000 miles. It is 20 degrees today. When I start the car up there is this knocking sound from the engine. Once the car warms up the knocking sound only happens when the car is in drive or reverse. When the car is in park or neutral it is fairly quiet. The sounds is still there but not as loud as in drive or reverse. I have done the routine synthetic blend oil changes between 3500-4500 miles.

My 2007 Hyundai Sonata has a knocking sound when I put my foot on the brakes. It has 82,000 miles. It still has the 100,000 mile warranty. The brake shoes was replaced last year. Does it need new shocks?

I was driving this morning after doing a brake job (nothing to do with the problem, just anger coming out) made it about 10 kms and noticed when i took my foot off the accelerator, the heater fan powered down a bit, and back up when I gave it gas...noticed a knocking sound from the engine...pulled into a gas station and put it in park. After a hard time idling, it cut out. I started it again and the idle was not good at all. kept cutting out. Got it going and made it home with the same sort of power issue. Tried to start it a couple times and same issue with the idle. Sputtering quite a bit and noticed quite a bit of exhaust coming out. When I backed it out of the garage, I noticed a small puddle of oil.

2006 Sonata LX. It's only on a cold start up and lasts for about 30-45 seconds tops..and then it goes away. Car has 74k on it. Treated well. Only use synthetic oil and no check engine lights. Last oil change I put 5w 30 in it. I know it says to use 5w 20. Could this be the problem?

I recently changed my ATF. I refilled with Hyundai SP-III like a good little boy. The ATF fluid level is correct. It's right in the "Hot" range when the car is idling at operating temp.
Now, when I back out of my driveway when the vehicle is totally cold, then put in Drive, I hear a slight knocking sound after I get about 50 feet away. It's a single knock, not very loud, but discernible. If I drive even 1/2 mile and try again (i.e. back up a bit, then put it back in Drive), I can't reproduce it. It's only when the car is first backed out and driven away.
I have around 15K left on the warranty. I'd feel silly bringing it to the dealer for this, unless someone knew of an issue this might be a symptom of.

For the last year or so i have been annoyed severely by a clunking knocking sound from the rear (possibly passenger side) of the car. The noise occurs when there is torsion occurring or a sudden change of direction. I can go over a huge speed bump or pothole and not hear a thing yet the slightest change in direction or torsion will cause this extremely annoying heavy metal clunking knocking sound. I tightened every suspension system related screw in the rear of the car and the noise is still present.
The car is lowered on H&R springs (approx. 1.4 drop) so im wondering if maybe there is an additional stress that has been torturing the sway bar links for the last 3 years causing this noise. Or could it be the shocks (which are working properly)?

I got my Sonata at 27k, its now at 76k and the cars been great although I had the following issues.
I've noticed sometimes when I startup and shift into reverse the car jerks a bit and its not a smooth transition. However other times the car is very fluid in switching gears. Should I take it in to have a look at it?
Also when I am turning onto a unleveled road (usually a higher road), I notice a creaking/knocking noise coming from the front of the car, also notice it when I reverse into a parking space sometimes.

My vehicle: 2013 Sonata Limited - 4500 mi. When I park on an incline, set the parking brake then release the foot brake, hear a 'creaking' noise from rear. Dealer says "it's normal and nothing can be done" ? I don't think so...

Noticed an intermittent creaking noise when the vehicle is in motion (low to moderate speed). The noise is not very loud but audible if you turn down the radio volume. It sounds like 2 hard objects rubbing against each other. I am positive it comes from the panoramic moonroof because it only happens if the moonroof is close. The noise goes away instantly if I open the moonroof ever so slightly. It has been intermittent and seems to happen at any temperature.

2012 Sonata Limited... I purchased my car in November of 2011. It had allegedly been driven for 5500 miles by a salesperson at the dealership.
Within a week, both my husband and I noticed that the cruise control would simply not go on every once in a while. The dealer claims to have taken apart the cruise control, looking for problems, but says there are no problems; that I should come back in after docummenting problems more specifically.
I also continue to hear the creaking noise in the sun-roof area. Allegedly, the Body Shop adjusted the headliner clips, but I still hear creaking.
I am most concerned with the cruise control, but annoyed at the dealer for keeping my car for over two weeks and having achieved nothing. I like the car, but this kind of a start with it makes me want to sell it and go get either another Honda or a used Volvo.

I just have a couple questions. First one I have a creaking in my front suspension when I go over bumps if I'm doing 50+mph it isn't heard anything slower you can hear it especially over speed bumps in parking lots. What could that be exactly? And also I'm looking to upgrade my headunit already got a single din but I'm wanting to replace the factory subwoofer. Can I replace it with a low power 8" aftermarket sub for better sound?

I have a 07 Sonata with about 94K on it. I have noticed the last few weeks after I am done with work and back out of my stall and turn the wheel to the right it makes a creaking sound. After this one time it won't do it again. It just does it if the car has been sitting for several hours.What it could be?

When coming to a stop and turning the wheels to the left, there is a creaking noise from the right front strut. This is also the strut that has an ever so small clunking noise when going over small bumps at low speeds. If I turn left at low speeds but don't apply the brakes, there is no creaking sound.
Car has 42,000 miles, original Michelins and original front brakes (50% pad left), and original struts!
