Sonata NF (2006-10) :: Jerking When Accelerating Until The Car Warms Up
This is in regards to my daughters 2009 I4 Sonata. In cold weather, like we are having now in Chicago. After the car is sitting all day or overnight, it will jerk (nice technical term) when accelerating until the car warms up. What is the problem is and how to resolve it?

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.

When coming to a stop in my 2007 Hyundai Sonata GLS with a 2.4 4 cyl engine all of a sudden you get something that acts like the car is jerking or surging or rough idling or something. Hard to tell exactly which but if I put it in neutral and rev the engine a little it smooths out. Only happens when coming to a stop. What caused it?

Doesn't happen all the time but when it does it is obvious at 45 mph. Not there at no load on engine. No code shown.
View 8 RepliesSonata NF (2006-10) :: 2.4L Engine Rattle Noise At High Load / RPM
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.
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.
View 1 RepliesFord F-150 (2004-2008) :: Jerking Under Load Like Engine Is Cutting Out
I'll try to explain what the truck is doing best I can. I'm not sure if it's the engine or tranny. When you lug the truck on a hill or put a load behind it and lug it the truck jerks like the engine is cutting out or the tranny is jerking, I can't tell which. You can drive it all day long on a flat road or small hills and you can't make it do it. It does it worse going up a hill with a load behind it. You can lug the truck on a steep hill let off the accelerator and mash it back down and it will do it almost every time. I've tried overriding the overdrive and it still does it. If you keep the rpms above 2000 up a hill it won't do it. I've had it checked by a transmission shop and they couldn't make the truck do it. Also it doesn't throw any codes or put the check engine light on when this happens. 2007 F150 supercrew 5.4 auto, with 88,000 miles.

I started having an issue when the weather changed here on the East this weekend. When I start my car in the morning the engine knocks for about 30 seconds and then stops. I also recently got an oil change at some local mechanic shop and wondered if that might be the issue. I checked the oil and it was stellar this morning but I'm not sure what kind they put in there. I would assume it's the required type.

I'm having 2008 Sonata Limited model with 60k miles. i was on a busy street when my 08 Sonata died and i had to coast into a parking lot put it in neutral and restart my car. This is happening two or three times per week. I reported this issue to nearest hyundai dealership and they are not able to figure out this problem. Again this week I am taking this car to them to find out the root cause. What it could be?. Right now I'm kind of scare to take this car to outside.

The video below IS NOT my truck, though my truck makes the same sound. Mine isn't nearly as loud as the truck in the video at idle, but gets much louder when under load at about 1700-1900 rpm. If you take it easy accelerating it doesn't get any louder than at idle. At cruising speed in third it isn't audible. The trans in my truck is a 1979 C6. Again, not my video. Same noise though.

Sonata NF (2006-10) :: 2008 Transmission Not Going Into D
All of the sudden it's not going into D, instead wants to manually be driven and having to downshift instead of upshift... so weird. It' erratic. Would it be a sensor, or internal issue with the transmission? Or shifter just sticking?

At the beginning it was just CEL on. I checked the code and change transmission range sensor but it worked for few days only. Light came back and transmission sometimes stop to shift automatically. D1 on display and driving only on first gear, but when I switch to tiptronic - manually everything works great?!
View 2 RepliesSonata NF (2006-10) :: Transmission To Hang In Between 1st And 2nd Gear
Just got my 06 3.3 GLS. Sometimes it seems to hang in between 1st and 2nd gear. No amount of throttle will make the car go or rev up until you let off and it changes gear. Then its fine. 79k miles, no cel. When i say it wont rev it will be at full throttle and engine and vehicle speed doesn't change. I just had the heater core replaced but not sure how this would relate to that issue? Someone said he thought maybe the trans needs to relearn its shift points after having the battery disconnected but not sure I buy that.

I went for my regular oil change and I asked my dealer to look for a strange vibration coming from the front wheels mostly noticeable at 30KMh and over 70. He diagnosed a vibration coming from the tranny. Wheel bearing are fine and tires and brand new (Toyo Tourevo) and freshly aligned.
My dealer opened a case with Hyundai Canada to have my tranny changed. BTW, Sonata NF 2010 I4, 5 speed auto trans. 50,000KMs
Sonata I45 (LF 2015+) :: Cold Start Car Jerking When Hit Accelerator

View 11 RepliesSonata I45 (YF - 2011+) :: Jerking In Reverse And Bucked When Put The Car In Drive
I have 2011 Sonata with just over 3500 miles on it. About three weeks ago I was driving down the road going about 45 mph when my sonata jerked like I had hit a pothole. I pulled over and checked it out and saw that I had not hit anything. When I put the car in reverse it jerked, and when I put it in drive the car bucked badly. After that, it had almost no acceleration as if it didn't want to get out of first or second gear. I took it to the dealership and they were able to recreate the problem and called it an "Intermittent Hard Shifting Transmission."
They told me they had to replace the transmission, which they did. After they replaced it they said the car was still hard shifting. So they replaced the transmission again, and again the problem persisted. Yesterday they told me they were ordering a brand new transmission, blaming the problem on the fact that the previous transmissions were re-manufactured.
I'm waiting to hear back after they install this "new" transmission. Maybe the third time's the charm, but this seems ridiculous.
