I bought my sonata with about 48,XXX miles about 2 months ago, and now it has 52,500 (im a student - dont drive much). Anyways, whenever i start my car up and drive down the road, when the car shifts in to third, i hear a slight knock. almost like a little gong - metal on metal.
Once it does it the first time, it doesnt do it anymore. Im guessing temperature could have a factor?
I noticed that recently my 2007 Sonata (108k Miles) is making a knocking sound when it shifts into second gear. It happens only when I back out of my garage and drive down the street and the car is cold. After that there is no more noise, and the transmission is shifting through the gears smoothly.
I recently replaced the transmission fluid, about 5k miles ago and I used the recommended type.
I read other postings with people having the same problem, and in those cases they pointed to the ABS self-check which occurs when you first start out. But this is definitely not my case as the noise is coincidental with shifting into 2nd gear and it only does it when the transmission is cold.
Could this be caused by the fluid temperature or maybe because the fluid has not had a chance to circulate through the transmission and fill all the cavities? Its rather strange thought that I just noticed it in the last month or so, if that were the case I should have had this problem before.
I have a high milage (210K) '07 2.4L which has a slight engine rattling noise at idle RPM at cold and operating temps, in gear or park. It is a fairly constant noise at idle but does vary a little. Otherwise, engine/tranny operate beautifully with no obvious problems.
I am concerned this could be a timing chain/tensioner related issue although I also wonder if it may be some other component. I have not been able to determine the source or location of the sound.
Sometimes mine shifts nice and quick, but sometimes it also shifts soft and slowly with a slight "flare" between shifts. Seems like it shifts better the harder I drive it, but I try not to drive like that. Dealer says everything seems normal to them. Maybe it's the adaptive transmission?
View 32 RepliesI have a 2002 Hyundai Sonata (automatic transmission) that has recently been "jumping" when the car shifts between 2nd and 3rd. This happens only after the engine is "warm", and does not happen in any other gears or when I downshift.
View 1 RepliesI bought a 2010 GLS 4cyl and within the first week started having shifting issues. Initially it was only when it was colder than 30 degrees outside and would only shift harshly between 1st and 2nd. Once I had driven a few miles and warmed the car up, everything was OK. It's still an intermittent issue, but now it will do it when outside morning temps are in the 50's and 60's.
I've read the TSB for 6cyl 09's and saw a post in the Santa Fe forum that sounded identical, so at least I'm not the first to experience this.
I took it back to the dealership knowing it probably would not shift badly when they test drove it because we had run out of cold mornings. I picked the car up after they reset adaptive learning and said there were no updates available for the computer. (And also being told I had bad gas in the car. Another story for another time...)
Until it starts doing it at fairly regular intervals, there isn't any use taking back to the dealership as it's very inconvenient for me to get there.
I checked the link that had TSB's and didn't see anything for the 2010's. Also, is there any place where I could check and see when software updates come out and what issues are addressed?
Replacing the knock sensor on a 2009-2010 Sonata with a 2.4l? Where exactly is it located and what has to be removed?
View 2 RepliesI went to Jiffy Lube and got an oil change, fuel system cleaning and cabin air filter replacement & sanitizing. I drive an '09 Sonata with 112K miles. When the car came out, I pulled away and noticed that the airbag symbol on my dashboard was lit and the center console was flashing that my passenger did not buckle their seat belt (I didn't have a passenger or anything on the seat). I went back in and after they looked at it, they said they couldn't find anything that could've happened at anytime and was a "horrible coincidence."
Hyundai ran a diagnostic tests and one of the 4 things that came back was B1389 (in addition to B1516, B1324 and B1515). B1389 signifies "Oil Temperature Sensor Circuit Failure." If the guy changing the oil damaged this (does this even get touched on an oil change), could that have offset the sensors for the airbags?
I just don't see how they done the above listed work and coincidentally my airbags are all deactivated afterwards. I'm reading a lot of bad reviews online, including quite a few for NOT putting oil back in the engine after the change.
I have a 2009 V6 Ltd with about 15k miles. It has always seemed to shift a little too hard from 1st to 2nd and from 2nd to 3rd under light to medium throttle. Does this sound like a transmission ill that can be fixed by adjustments?
View 8 RepliesI have a 2006 Nissan Sentra with about 58k miles on it. When it shifts into gear I hear a slight squeak, almost like a bushing or something like that. It does not sound mechanically related. More of something squeaking or loose etc.
View 9 RepliesRecently got quite a noticable clunk/knock from the front driver side of my '10 Sonata with the 2.4.
Only happens at low speeds, most notably in parking lots.
My best guess is a stabilizer link or a ball joint.
Took a video to explain the sound I am hearing.

2008 3.3L 77,800 miles (approx). Bought this car as a replacement for my totaled 2006 back in May 2011. I have noticed on morning starts or hot starts after car has sat for about 30 min, a 'Rod knock" sound that quits exactly at the same time the oil light goes out. I bought this car with 60K on it, with all 60K maintenance items done by dealer. I have since replaced oil on 5K intervals, have used 5w-30, 5w-20. Genuine Hyundai filters and one Fram cartridge. Nothing has changed. The car runs ok, other than horrible gas mileage ( average 2.8 LESS than my '06 under same conditions and verified by manual calculations). While the car runs ok, the noise unnerves me every time i hear it. Once i get lights out on oil pressure it never is heard again until the next start. Is this something I need to be concerned with? I had a sample of the oil analyzed at 65k, and came back good.
View 3 RepliesWell, After reading about the weird transmission issues these cars have...mine finally started to do it. It will clunk, shake the car when it shifts and downshift for no apparent reason. All of this does NOT happen all the time. The noises that come from my transmission do though.
I can have the car in Drive and have my foot on the brake and I can hear a grinding/low power steering fluid like sound that comes and goes. Its worse when I shift from Park to Reverse though. It sounds like air being released followed by a bunch of faint grinding noises.
I currently have a 2006 F-250 6.0 with 187,XXX.
My problem that i am having is that the transmission recently within a couple weeks started acting weird about the same time 3 of my fuel injectors started failing. When i start up the truck and put it into drive it takes about 3-5 seconds to shift. Once it's in drive it runs pretty well but it will start shifting out of normal when i go to accelerate. Also when i go to slow down sometime the transmission shifts hard to a lower gear. I also have a video of the sound that it had started to make since its hard to describe.
Here are attached videos and photos. I want to hopefully fix the problems myself so i can learn more about my truck. I am going to handle the fuel injectors here soon since 2 are failing and ones about to these have been causing the truck to shudder at around 47-53 mph but after that its fine.
The transmission is stocked and never been altered, i do admit for 3-4 years I have changed the fluids or filters.
The truck is bullet proofed, sct tuner, upgraded turbo from stock, 4" exhaust, head studs and new everything when the engine was rebuilt and bulletproofed.
I plan on going to ford tmw to have them figure out the problem and hopefully its just solenoids so i can fix it myself. I have a link posted also where you can hear the noise it has been making when in R P and when shifting going down the road and it is a automatic.

Ok I bought this truck with a bad engine 5.4 3v had rod knocking. I rebuilt engine got it all back together and in truck. I did replace cam phasers and solenoids. After driving 20 mins or so it would start the phaser knock at idle in gear so I put a oil pressure gauge on it and cold had 55 psi after running 10 mins or so had 15 psi at idle then would drop to abought 9 psi. I am thinking I got bad cam bearings or something for some reason don't know why. I did it but I took oil cap off where you pour in the oil. Had to force it off it was pulling that much vaccum ones cap was off oil pressure jumped up to 25 psi. What could be causing this.
View 2 RepliesI drive a 06 Sonata 2.4L Automatic with 124,000 miles. I noticed that when I'm going about 45 or 50mph the car will slightly jerk continuously. It almost feels like its either hesitating to up shift or down shift.
View 4 RepliesI 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
I've noticed that when I am driving my car in the morning there is a slight vibration in the car, it feels like the rear, but it could be the whole car. After I drive it for a while this vibration goes away. The vibration never comes back again until the next morning, even when the car sits at work for 8 hours the vibration doesn't appear.
It's not a violent vibration, it's very subtle but it is noticeable. I'm thinking that most likely it is my struts and shocks, I know that they probably need to be replaced soon (with our shocks being crap).
I don't think my wheels are out of alignment as the car doesn't pull to any side at all and my brakes are also good and not sticking. The car has 86K on it. What is going on and if I should be more concerned than I am or is it just worn shocks and or struts?
My sister has a 2006 sonata V6 3.3, she got in 2007 with I think 20,000 miles on it, it has 180k. now. For the first few years she took it to the dealer for all the maintenance and oil changes. She has kept up with the oil changes and I think all the recalls were done.
There has been so slight noise at start up, but nothing I thought was too unusual for these kind of motors.
Yesterday she had an emergency with one of the kids, her faithful sonata fires up with an incredible amount of upper end noise, and it looked like it was burning oil. The engine was turned off immediately.
Her husband tried to start the car about a half hour later, he said it was hard to start, ran rough for moment, he revved it for a bit and it smoothed out running normally. No codes and no CEL. Oil level was good. Oil filter is a fram I think.
I started it a few hours later there was some lifter noise that quickly went away after a rev. Other than that it sounded normal and drove normally, normal exhaust from what we can tell.
There were no codes. and so far it has not done it again. But she is worried the engine is about to fail and she can't trust it with transporting her kids.
Was a timing issue? stuck valves? oil pressure? Oil Pressure to the cvvt (OCT?) maybe? They can't afford a new car right now, is this something easy to fix or is it a warning the motor is about done?
So when I turn and am hard on the gas I get a clicking and slight clunking sound from the front end. Wants to confirm its the CV joints before I rip it apart?
