Sonata NF (2006-10) :: 2009 3.3 V6 - Transmission Slipping While Driving On The Highway
May 20, 2012
I have a 2009 Hyundai Sonata V6 3.3. I'm currently about to hit 65k miles. About 2 weeks ago i felt the transmission slipping while I was on the highway. Yesterday my check engine light came on. I took it to my mechanic; according to the reader, the Dampener Clutch System was the problem. This morning when I took the car out, I realized that the Check Engine light went away but still could feel the transmission slipping.

My 2009 sonata started having issues with slight up and down accelerations while cruising and the check engine light would come on Then during start up the engine would accelerate up and down about 1500 rpms. I have taken it to two dealers neither could find anything wrong and said their was no record of an event on the computer. Now the car is stalling while driving, once at highway speed. It has happened three time this week. After coming to a stop, I wait a few minutes and the car starts up like their is nothing wrong. The engine light comes on for a while.

I own a 2009 Kia Optima 2.4 Auto. My good friend and his wife own a 2009 Sonata 2.4 Auto. My car has around 40k and his has 50k. We both notice a very strange noise that started well over a year ago on both cars. After driving for a while, then you stop at a stop light or go through drive-thru, the transmissions BUZZ. If you put the car in Neutral or Park, the buzzing stops. Even if you put the car back in gear, it won't make the noise again until it decides to do it again. They both only do this when the transmission fluid is hot. Never does it when they are cool and have not been driven. Both cars have had the transmission fluid changed at 30k and this noise was mentioned to both dealers at the time. Both cars had transmission related TSB software updates done, but nothing changed as far as the noise. Neither car would buzz for either dealer, so they were no support. I just find this odd that it is BOTH cars. Of course they have the same engine and trans, I just wonder how many more folks have this odd ball noise. It really sounds like a power steering pump thats low on fluid. Fluid levels are perfect.

I have an 06 sonata 4 cyl automatic.Today the transmission was slipping in first gear like the car was revving in neutral.Then after restarting the car it was completely normal. Code P0731 showed up.

I own a 06 sonata with 95000 miles. Recently I've been having issues with my transmission. It occurs only at slow speed when i travel in first gear. What happens is when the car is moving, it feels like it shifts into neutral but indicator still shows D in the cluster. I press the accelerator nothing happens it just revs,no increase in speed whatsoever.
So that rules out slipping issues. Now i narrowed the problem down a little more whenever the problem crops up i shift the gear lever into sports mode, i feel a jerk and car shifts into first gear and it moves. If i dont shift into sports mode it catches gear in about 7 seconds.No fault codes.
And if i rev it high transmission goes into limp mode and stays in 3rd gear till i restart the car.Then i get P0731 incorrect first ratio.Changed ATF 7000 miles ago. Could it be a faulty range sensor?

I have a lot of wind noise in my 2 front windows when driving highway speeds, no water leaks. I cannot find where it is coming from either, I assume it is either air rushing over the mirrors or thin glass. Sometimes it is worse than others, not sure if cross winds etc. Is that common in 2009 Sonata. My old 2003 Malibu, much quieter but mirrors were slightly more rounded if I remember.

We have a 2009 Sonata with barely 50k miles - always garaged. It has been a great car but recently has come up with a couple of quirks.
I was driving last week and heard a loud "pop" behind me. Really loud..... I pulled over and found that the left rear window was missing!
I took the car to a local auto glass place and they found the missing window down in the door, I really though that it had fallen out and actually went back to the spot on the road where the noise happened and looked for it.
Anyway, the glass shop lifted the window back in place but had little interest in making the power part work again.
Now, I have had power windows fail on other cars before but they always got stuck, I have never had one "disappear". Would this be a safety issue that Hyundai might cover?

I recently had the transmission fluid changed in my 2009 Sonata NF 4 cyl. Current mileage is 60,000 miles. Directly afterwards, the transmission started "sliding" into 4th gear from 3rd gear. I assume that fluid contamination has caused a clog somewhere in the transmission. I have had the tsb done on the car for the transmission and the fluid had been exchanged @ 30,000 miles prior to this service.

I have an 09 Sonata that jerks when automatically down shifting just before coming to a stop or slowing to make sharp turn. Car has 130k miles and I've never changed transmission fluid. BTW...it's been a GREAT car!

When I was at about 40k miles I started to have this problem. Driving above 35mph the road noise started to get louder. I first thought it was my tires but the noise went away after driving about 1k miles. Now I'm at 72k miles on different set of tires and the noise is even louder. According to a few mechanic shops, they say that there is not enough air flow going into the engine. But I'm not sure if that's the problem. It's not under warranty anymore and I can't just take it to the dealer to find out what's wrong.

My 2009 Sonata 2.4L GLS is jerking at around 20mph when I slow down for the first 10 minutes that I start driving. I have taken it to the dealership 2 times. The first time, they updated the computer module for the transmission, however the problem was still there afterwards. The next time, I did a transmission fluid flush and fill, but yet I still have the same jerking problem.

I'm having a serious problem with my 2-year old 09 Sonata....
It happened for the third time: after driving for a couple minutes, numerous dashboard signals flared up and my power steering suddenly seemed to turn off - all in the middle of driving. The first two times I took the car in, they found problems. One of the malfunctioning components was the timing belt, and they replaced it for us. After the third time, however, they couldn't find any problems and my car was deemed "perfectly normal." They didn't do anything for us.
Now, I'm left with a 'normal car' that I know will show the same problem sooner or later.. maybe in a more dangerous situation than the previous 3.

I have a 4 cylinder 2009 Sonata with an automatic transmission and it does not accelerate smoothly when starting out from idle. A slight touch on the accelerator pedal causes the motor to accelerate hard as though the pedal was pushed down a lot further than "a slight touch". Is this normal or should this car accelerate smoothly? I am wondering if there is a common problem with either the accelerator pedal sensor or maybe with the throttle servo.

My wife's 09 Sonata SE AUTO 4-cycl.. I drove it last weekend and discovered a strange noise that can be heard after driving for a while at normal local road speeds.
The sound is like a combination of a whine and something that sounds like radio static. It can be heard very easily with the radio off and stopped at a red light. However, this sound also exist while the car is in motion. It becomes more difficult to hear as the road noise increase.
When I shift from D to N while stopped or driving, the noise immediately goes away. When I shift back to D, it sometimes comes back.
The consistent pattern seems to be that the noise will occur after having driven for a while at a consistent speed of at least 30-40mph. If I drive around the neighborhood for a while at low speeds and then stop, the noise will not be there.
I have not made effort to hear it from the outside of the car.

I have the Sonata 2013 GLS and I've noticed the transmission is slipping. I drive it hard.
So the guy said he was going to call me, never called me back. I called 3 times and no one knew what the 30k service included. it was a simple question, I just asked if they could check when was the last time I had a transmission service.
I tried checking the level but it has no dipstick. what should I do? my car has 54,000.

I have a new 2011 F150 4x4 6.2 liter with about 1200 miles, 6R80 6 speed Transmission. I haven't liked the shift quality since buying a little over a month ago. I think the upshift from first to second is kind of rough and it feels like it's slipping a little from second to third gear. I've read a lot of negative posts/reviews on the 6R80 transmission, and some people have said it got better over time, or it got better with more aggressive driving. I do notice it shifts better if I drive it a little harder. The build date according to the sticker is 4/11 and I don't think there are any TSB's for PCM updates for this year/engine/model. I'm wondering if I should bring the truck in now for the dealer to take a look or drive it for awhile longer to see if it gets better?

4400 miles on it. Over last few days the transmission started to slip. First gear engages fine, but the change to 2nd involves a rev....(with no acceleration) till it finally grabs.
Reverse into my garage up my slight incline of a drive does same. Slip rev....slip rev... No gear noises.
Tried to check fluid level...(that's what it sounded like to me) but sealed system.
Taking it in for warranty check/work.

I have a 92' Areostar XL 3.0 2WD. When I first start it and put it in drive it takes a few minutes before it kicks in. After a few minutes of driving it doesn't have a really bad problem (only a few times has it slipped in lower gears.) I was told it could be a clogged transmission filter, old transmission fluid that is glummed up, or pull belts need to be tightened. I have the van up on jacks now and was getting ready to change the filter and fluid but I decided to get some advise first before I screw things up or do any unnecessary work.

My 2009 Santa-Fe AWD Limited is sick! Starting from a stop, the vehicle has abrupt shifts with the transmission slipping (RPM revving). Seems worse when cold. Checked the fluids, and found ATF fluid in the engine oil and engine oil in the ATF fluid. Quick internet check suggest a leaky vacuum modulator valve. (There is no way the fluids went in the wrong holes, the vehicle only has 69k kilometers on it, so it still has original ATF fluid, and I recently changed the engine oil myself.) So, do you think this is the correct diagnosis? How hard is it to change the modulator, and where is it located?

I have a 2011 F-150 with the v-6 automatic. The truck has just under 45,000 miles on it. Couple of times I have started it up in the morning to head to work, and when I put it in gear(fwd or reverse) it seems to slip at first. It does it just the one time, then it will be fine. It only happens in the morning after sitting for the night and when it is cooler(Arizona here so hasn't gotten much cooler than the 50's at night so far). I need to take the truck in for another issue, but thought I would ask on here first.

My 2004 Accent transmission with 145k miles all of a sudden started slipping while driving. It would be fine until i needed to slow down and then step on the gas again. It wouldn't catch right and it would slip. At first the pull of the slip was very slight and at times now it is very rough. My check engine light does not turn on when it slips slightly, but only when it has a really rough slip will it turn on. I had it checked at the local advance auto parts and i was told it has a 4th gear ratio that is off. The only thing that confuses me is that when i turn the car off and on it resets and works fine, that is until it slips again. If i drive carefully it usually wont slip. Could it be an electrical problem?? I changed my speed sensor when my car had about 132k miles because it went out, i replaced my ignition coils, new spark plugs/wires, tranny oil change, and filter change.
