Sonata NF (2006-10) :: 2008 - Jerks When Slowing To A Stop
Mar 26, 2013
When I slow down to stop my 2008 Sonata it jerks. It is an intermittent issue. The car has 95,000 miles and when I called the dealer I was told they would start with changing the transmission fluid and go from there. I read on some other posts of this same type of issue being fixed by installing the latest software for the transmission, but this was related to 2009 & 2010 Sonatas. Is it possible that installing some new software would work on my 2008?

I have a 2010 Hyundai Sonata GLS that I purchased just over two years go. I have a couple of issues with it at the moment.
My first problem is I clipped my drivers side side-view mirror and a little plastic piece inside the side-view mirrror housing where the bolts go thru broke off. I checked with Hyundai and it seems like you can't purchase that plastic piece from them(they make you purchase the whole side view mirror). I also checked around at local junkyards but none of them had a 2010. What I can do here?
My second problem is when I'm slowing down to a stop and my speed gets around 10 mph or so the car jumps/jerks. It feels like it's almost skipping a gear or something and it's very noticeable. I was wondering if any of y'all have had that problem before and if so what did you do?

I have a 2004; 4cyl Sonata, that jerks when I accelerate from a stop light or when I step on the gas, it jerks and sputters while passing another vehicle, then it gains speed?

The boss has an 08 Sport Trac, V8, 4x4. It has the hard bump when slowing to a stop. I've read here that there is a TSB to reprogram the transmission. Called a dealer in Ft. Worth to schedule appointment. Service guy say there is no TSB. Looking for a copy or number or anything on the TSB?

When I accelerate from full stop with 3/4 throttle when car gets to 60-70 mph it stops accelerating for 1 or 2 sec, there is is also a little jerk. After that it continues to accelerate normally. The problem is not present if for instance we drive 30 mph and then use 3/4 or full throttle. I talked to dealer and they said there might be a little jerk but nothing more, and it might be solved by software update. In my opinion its definitely not a slightly jerk, car completely stops to accelerate for a moment. Car has about 45 k miles so its almost like new.

I have a 2004 Volvo v70 (not turbo) with 150,000 miles. After driving the car 5-10 miles, when I slow down to about 10 mph, the car jerks. Acceleration is fine with no apparent transmission slippage. I avoid the jerking by shifting the auto trans into neutral when slowing. It seems like it might be a mount somewhere. Dealer said that it is the beginning of the end of transmission.

I have a 2006 Hyundai Sonata GLS V6. Recently the area I live in received 2 feet of snow and ice. I of course cleaned off all the snow and ice and started her up. I didn't drive anywhere that day since the roads were not clear. The next day I drove 15 minutes and upon reaching my destination's parking lot, the Sonata went into a jerking motion.
It seemed as if it wanted to stall out, like I was driving a manual. However it's an automatic. I stopped the car, and later when I went to leave it did it again. Once I got out of the parking lot and above speeds of 20 mph everything was fine. No more jerking motion.
The next day, after some time driving it does it again. My car never actually "stalls" or shuts off, it just jerks and once I can press the gas and go, it stops.
There are no odors or sounds and the car only does the jerking motion sometimes.

I currently have a 2006 B6 w/ approx. 95k miles on it. A couple months ago I had my catalytic converter replaced at the dealership and then about a month ago my car started having issues with stalling.
Symptoms:
-Car drives normal - no loss of power or anything, but then will randomly stall when coming to a stop or slowing down, taking my foot off of the accelerator. After it stalls the red alternator light comes on. Check engine light comes on and off - lately on most of the time.
-The issue has gotten progressively worse recently, but for the past month it has been inconsistent. Sometimes I can go an entire drive and not experience it and then other times it will stall nonstop. Lately, there have also been a few times where it's taken a few tries to start it, though this is recent as before it restarted perfectly fine.
-Recently, the car has started exhibiting symptoms at highway speeds as well, occasionally brief episodes where it will begin to jerk and shake. Usually stops as pressure is applied to the gas pedal.
-Also, have issues with the parking brake... the switch seems to have randomly broken in the center (no clue how) and I keep getting a parking brake fault. Not sure if this is related or an entirely separate issue.
I took the car to a very reputable independent VW/Audi shop and after several days they still have been unable to locate the issue. Based on the codes the MIL was sending the first visit, they replaced the low fuel pressure sensor and the cam position sender. Neither fixed the problem. So, now I have to decide where to go from here... They took off the labor and only charged me for the parts.

Notice roughness/jumpiness in the transmission when slowing to a stop, or crawling along (like in a shopping center)? it's quite evident on my car, and perhaps i just have a problem that nobody else feels.
It's as if the tranny is downshifting when slowing to a stop, and I can really feel it...makes it difficult to come to a smooth stop. and then if I'm moving very very slowly in heavy traffic, it seems to be "wandering" between 1st & 2nd...something like that...and it's very jumpy. Not smooth at all.
I realize that Lexus may come up with some reprogramming for trannies (that happened on my '01 GS, and it made a big difference).

My daughter has a 2010 Sonata with a 4 cylinder and an automatic transmission. She is pretty frustrated with an intermittent problem. Every once in awhile, especially if the engine is cold, the car jerks while slowing down. She believes it is the transmission when it down shifts. I have driven the car and have not been able to duplicate the problem myself. The dealer recently changed the mapping for the transmission in hopes that would work but it hasn't. The dealer hasn't been able to duplicate the condition either.

My Hyundai is giving me a major headache. I bought a 2009 sonata used a few months back. Not long after I got it, I was having issues with it jerking around 20 mph. Sometimes, it would have a few issues with it jerking some when I was taking off. This was only right after the car was started. I took it to a local Aamco. The guy told me that it was a 2-1 downshift pump. He "relearned" the transmission and the problem went away. Now, it is back. At the time, he did some research and thought it may stem from a calibration update they had issued. He didn't have the Hyundai software to try that fix.

I am getting a ticking sound when i am slowing down (applying my brakes) at say 35/30mph. The sound stops when I stop. This problem starts after my car warms up; doesn't do it when I first start up.
I've taken the car to 2 Hyundai dealerships and a certified mechanic and the problem continues. I first noticed this about a month ago.
So far no one seems to be able to find the problem. The mechanic did try by replacing the front brake pads. He said something about a "shims piece " and thought if we replace the front pads that would take care of the problem. The rear brakes or ok.
I'm still having the problem and I wonder if it's the rear brakes after all. I don't know what I can try now. Someone suggested going to Brake Check. I have about 1000 miles left on the original warranty.

Today my transmission suddenly disengaged while slowing down from 3rd to 2nd as if i switched to neutral.Car revved freely when i pressed accelerator. Then suddenly after a second it engaged again and shifted normally. Never had this issue before i racked up 1,29,000 KM on my ride.
I can't see it as "slipping" as there was no change in speed and it revved freely. Also I 'm due for fluid change. What can be the issue?

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!

Trans has new solenoids in the trans but is shifting too firm sometimes from 1-2 or 2-3.. It is tolerable going up, but when slowing down it jerks really bad from 2-1. Sounds and feels horrible for the trans and miserable during stop and go traffic. Ive had to switch it to Manual and start off in 2nd gear. Im deleted, with intake, and a custom sct x4 tune. My main question is there any way a new tune could have better shift points?

My 2006 Sonata V6 (88k miles) has an occasional power steering loss. It has only been noticed right after slowing down from highway speed. Total loss for a few seconds then comes back. No dash lights or noises, just cant steer - then can. Did all required maint. until 60k then just oil changes by me. Have read other forums about fluid flush, but that was for noise and I don't have any noise. This has happened with and without the Electronic Stability Control turned on. Other than that, runs great. MPG is about 25 or so (wish was 30 or so).

My 09 Sonata LTD V6 was sometimes idling erratically (revving and slowing) after starting a cold engine. It never happened in the previous 3 winters I have owned it. I took it to the dealer for service and they said an ECM update was just released, described on the invoice as "TSB 10FL002 FOR COLD START ROUGH IDLE".

I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.

I have a 2006 F150 4x4. When the engine an transmission is cold it jerks/ Bogs when it shifts. After it warms up it doesn't jerk to bad sometimes but you can still notice it. Also when it shifts the RPM's drop low causing it to bog and jerk. RPM's will go from 1600 to about 800 when it shifts. It is and auto transmission. Today I wanted to try something so I pressed the button to turn the over drive off. Well it shift real good with the OD Off. Seem like with the OD Off it keeps the RPM's up a little higher so it doesn't bog and jerk. I put an Edge Programmer on it, but that didn't work. Still does the same thing with or without the programmer. I changed all my spark plug and coil packs. Truck goes great until it shifts.

2008 GS460. 100K miles
I have noticed when I accelerate on a entrance ramp to the highway I notice the RPM meter jerks a little like it's trying to suck for gas or something else. I can feel it in the car too. This is the only time I have noticed this. I have replaced the spark plugs about 5K miles ago.
I did bring it into the dealership a few months ago to get the fuel pump replaced as I noticed a hissing noise under the drivers side read door. They said fuel pumps rarely go bad on the Lexus. The mechanic did some fuel pressure tests and said everything looks good. He also said noise is the return line back to the pump.

When I accelerate from a stop, the car jumps, slows down, jumps again, etc... I do hear a noise when I accelerate rapidly on the highway, almost like a leak somewhere, but I'm not really sure.
