Sonata NF (2006-10) :: 2007 GLS Rough / Shaking When Initially Started And Pull To Stop
Oct 14, 2012
Have a 2007 Sonata (2.4 L inline 4) and been plagued with rough/shaking car when initially started and pull to stop, and generally goes away when fully warmed up. Recently had oil change and service area switched me to a lower viscosity oil (5W30 to 5W20) and checked a solenoid and it was fine. Also did a fuel service treatment I suppose in an attempt to flush out stuff........I was a little surprised he didn't pursue talking about tuning up aspects but maybe none of those codes flashed......a repeating code I do have is Code 11.........though I confess when the codes refer to emission stuff I sort of ignore them.......

2007 Accent Hatchback. Put gas in it from an Exxon we have bought from before with no problems. My kids car, running on vapors, put 1/2 tank of gas in. Pulled out of gas station and car starts running really rough, shaking. Still running though. I have gathered some knowledge from other threads, like timing belt needs to be changed (65000 on car). I replaced the plugs as an initial attempt at correcting the problem. Runs better, not great. Saw a thread with changing to better gas, will try that.

My 2009 Sonata (4 Cyl.) has begun to downshift very rough while coming to a stop from about 20 mph. At first I thought it was the brakes, but now I'm convinced it's the transmission. Essentially it "jerks" a couple of times before stopping. It started happening at 30,000+ and only happens when transmission is still cold. Once I've driven for a bit it doesn't happen.

2007 Sonata V6. He's spent many hours and a good chunk of change at the dealership trying to get it fixed and nothing has worked yet. They honestly have no clue whats wrong which kinda scares me.
First off here is his problem. Occasionally when he starts the car it will idle very rough and struggles to accelerate to 30-40mph. When this happens he pulls over and shuts the car off for a few minutes then it will run fine again. When all of this happens there is no CEL or any light at all that flashes or comes on the dash.
Here is a list of things that have been replaced
Fuel pump
Throttle position sensor
Crank sensor
Plugs, wires and coil pack

Bought the Camry new in May 2006. Besides the oil hose leak (which a recall fixed), it's been a perfect car.
Fast forward to the present. I needed a brake job, so my master mechanic buddy installed front and rear powerslot rotors and akebono performance pads and flushed my brake fluid. No problems with the brakes.
A few weeks later I wanted to treat my car to a 90K full transmission flush (it's first transmission service). I had it flushed at a local toyota independent shop. They used WS fluid. A few hours later, my transmission which shifted perfectly fine before the flush started shifting weird. I thought the computer had to relearn my wife's driving style. When she brakes hard (if she's going 50 and the light turns yellow and she brakes hard, her car slows down normal, but right before it comes to a complete stop is when the car shakes. She said it started right after the transmission flush.
A few days later when she was at a red light, the car check engine lit up with a check battery (she thinks that's what it said on the screen). When the light turned green, it wouldn't accelerate, but it would roll forward when you let go of the brakes. When she got to a safe place to park/stop she turned off the car. A few minutes later she turned the car back on and it was fine.
I told that to one of my buddies who had something similar happen to him in his 06 Mustang GT, the Ford dealer cleaned his throttle bottle and maf sensor and he was on his way. I had my throttle body and maf cleaned. Now with new brakes, new brake fluid, a flushed transmission, a clean throttle body and maf, I thought everything was good.
On the freeway , the car would not shift to 4th gear or higher. So I exited the freeway, drove the surface streets to a independent Toyota shop. Left the car there all day, they could not find anything wrong. So, right now everything is back to normal except the shaking when you are almost at a complete stop, which started AFTER the transmission flush, what that might be?
To describe the shaking problem, imagine I'm driving 45-50, light turns yellow, I slow down, 50-20 is fine, maybe even 50-15 is fine, but the car shakes right before it fully stops.

I was at a stop light. The light turned green and I let off the brake. Just then the car died while I was in drive. I couldn't put it in park. I was a little panicky. It broke down on a major road in morning traffic. I tried starting the car. Nothing. I think I managed to move the shifter into neutral and tried starting the car again. Not a problem this time. Maybe a few minutes had lapsed. It bothers me of course because I've only made 4 payments on it and I'm planning on a trip out of town this weekend. After I dropped my son off I made it home without incident. What caused this?

I've got a troublesome misfire in a 2007 Sonata V6, 70k miles, which I have been trying and failing to track down for a long time.
More than a year ago, the owner of the car complained of rough idle. When this was first mentioned, I looked at the car, she and I talked, and I concluded that she hadn't changed the oil in some 20k miles. ...... Nothing else seemed wrong. I changed the oil, thinking that what she needed was an oil change.
Some time later, I was in the car myself and all of a sudden felt a strong bucking. Must've been a misfire. I recommended taking it to the Hyundai dealer, thinking the so-called 100k mile powertrain warranty would cover whatever it was (it didn't but whatever).
We drove it to the dealer. The dealer firstly informed us that the CEL had burned out, so we had missed some codes. The dealer further us the car needed new plugs and replacement of both upstream O2 sensors. Here was what the mechanic wrote:
"BETWEEN 35-40 PUT CRUISE ON AND WILL FEEL. CHECK AND ADVISE COMES AND GOES. MULTIPLE CODES STORED IN SYSTEM. ... P0300 RANDOM MISFIRE (ACTIVE), P0140 O2 SENSOR CIRCUIT NO ACTIVITY, P0154 O2 BS S1 NO ACTIVITY. WATCHED O2 VALUES AND FOUND ERRATIC READINGS. FOUND TSB 10-FL-012 SUGGESTING REPLACEMENT OF BOTH UPSTREAM O2 SENSORS. RECOMMEND COMPLETE SYSTEM TUNE UP FOR RANDOM MISFIRE. HOWEVER MISFIRE COULD BE RELATED TO O2 ACTIVITY.
So the owner went to a different mechanic and had the plugs, upstream O2 sensors, and one of the downstream sensors replaced. All OEM, I believe. ($$$!) (O2 sensor parts 39210-3C100, -3C200, and -3C400) Dunno why the downstream one was replaced, not my doing.
Following this, there was no real improvement. No codes either. The problem comes and goes, so maybe I thought it was fixed, but it has come back. Sometimes, it can be felt just slightly when the car starts cold. Other times, it can be felt just barely when driving at a consistent speed. Sometimes, the problem becomes really bad and jerks the car around. Other times, nothing.
What to check next? Coil packs? Intake manifold gasket? She never gets "top tier gasoline," but I would be skeptical that that's the problem. These are the top three suggestions I've heard.

So my sonata 2.4L has been freaking me out lately. Once it has been driven and warmed up good, it starts to idle rough at rest at lights and in traffic. Now the crazy thing is it idles even more rough if I switch it into neutral during those stops. One more thing is it idles the worst after I fill up with gas and get stopped at lights.
So what I have done:
Cleaned the MAF sensor with MAF spray
Changed spark plugs (I4 so it comes with coils not plugs)
Put Lucas Gas treatment in
So I'm getting no check engine light. So all I can think of is fuel filter. Or some other sensor. I mean I know it could be a coil so that would be the next thing I check. What this could be?

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?

Okay so I haven't driven my car in a couple of days, and when I started it today it started sputtering and shaking like it wasn't getting gas. I let it do this for about ten seconds to see if it would set a check engine light but it didn't. I shut off the car and restarted it, then it ran perfect.
I have had this happen to other cars if I let off the key too fast, but I don't think I did that today, I turned the key the normal amount of time. It only has 20k miles on it.

I have a great vw 2008 rabbit with 115,00 miles on her. I just completed a round trip. On my way back during terrible stop and go Washington DC traffic..I noticed the car started to rev a bit. After that the idle has been rough with some light shaking. No engine light, but it does sound almost like it is choking a bit. Not extreme..but definitely not the smooth engine sound I had. I am guilty of NEVER HAVING MAINTENANCE on her..so I had new spark plugs put in and a new air filter. The problem is less..but the idle is still on the rough side.

My cady hesitates from stop when accelerating just initially and then runs fine while driving. I have changed plugs, electronic ing, wires cap, rebuilt carb fuel filter. What can be causing this???

I have a 07 Explorer with the 4.6 that just developed a problem. It has 75,000 on it and has all of sudden started shaking at idle and acceleration. The acceleration issue doesn't seem to occur until after 45mph. I have cleaned air filter and MAF sensor. Still need to put a code reader on it. Where to start troubleshooting.

I have 2007 LS460 (bought a week ago) with 88000 miles on it. Recently I found a very strange issue, that the car shakes (you can definitely feel it, but not too serious) when I stop at red light.
But the issue goes off at night. It turns out to be the headlight. When I turn on the headlight the car barely shakes, so that's why I do not have the problem at night.
Is it the alternator's problem? Or the battery? I hope it is not the alternator..
In addition, I brought it in to Lexus dealer and they did a health check. They said they did not find any code and all systems are OK. Does it mean that if they say OK, then at least I will not see big problem right now?

I recently bought a 2013 gx and noticed a few things.
1. At high speeds 50+ mph the car downshifts quite often during rapid deceleration.
2. When coming to a near stop but not completely, and accelerate moderately to fast, lot of times there is a jerkiness when stepping on pedal initially. Is this normal or could it be something with the differential gearbox?

I had a valve job on my 2006 Bmw 750 li, when I picked the car up from the shop the engine was loud ,before the job it was quiet couldn't tell the car was on , it also shakes back and forth while idling at every stop light,and when I take my foot off the gas the engine kind of jerks I have taking it back to the shop several times and they seem to not know what it could be they have recalibrated the valves and it seems to not shake soon after I leave but right when I'm a mile or so away it starts to shake again, what could be causing this? I'm pxxxed I paid them close to 4000 to replace the valves and now the car is running rough.

I have a 2006 Hyundai Accent that won't start. My wife was driving home the other day, and while she was sitting at the light she said she noticed a sudden change in the idle. She said the car starting shaking a little and idling really rough. When she tried to accelerate after the light changed, she said the car sputtered and would barely go.
She was only a couple of blocks from the house so she continued home. The car made it the rest of the way home, but she said it never went over about 5 mph even though she was pressing the accelerator as she would if she were going about 30...the car just never responded. When she pulled into the garage the car died as she was turning. Now it will crank but it won't start at all.
I tested the crankshaft position sensor with my multimeter and it was bad. I bought a new one and put it on, and I tested it immediately. The new one works, so I plugged everything back in and tried to start the car...nothing, just cranks and won't start. It's getting fuel and fire as well (tested both), but it's not hitting on any of the cylinders.

I have a 2007 Ford Fusion 4.0L AWD. One day I went to pass a slower car and accelerated rapidly, but the car responded with loss of power and shook to a stop and would not re fire. I took it to the dealership and they said two cylinders were not firing and a fuse was blown. I looked on the internet and some people said their coils go bad or plug wires. I asked the dealership if that was the cause and they said absolutely not, but it's the ECM. They replaced the ECM and 2 days later my CEL came on and I took it back to the dealership and they told me my catalytic converter was bad and I could drive it until I had the money to replace it. Then a couple days go by and I was passing a tractor on the highway, I slowed down to 45 mph to make the pass and as I began to accelerated I felt a thunk, then about a mile later it started cutting out and shaking. This time it would re fire but idle rough. I tried on/off 3 or 4 times then it idled o.k. I then took it back to the dealership and this time they said it's all 6 coils.

So I recently took over my wife's 06 GLS 3.3 and gave up my 3.5L Saturn Vue Redline - Any ways the sonata has 60k miles on it and vibrates on the highway around 65-70 mph. Are there any other things I should be looking on with this car?

I have an 07 f150 v8 5.4 and it idles very rough. When i start it it seems to start really rough and just about everytime im stopped its shaking just enough to annoy me. Do you think its the spark plugs? I took into the dealer about a month ago and they said everything was fine. But its still doing the same thing. Also the A/C tottaly sucks is that they way it is? When I accelerate the cold air gets kinda warm and it doesn't get cold until i get up to speed.

I have Subaru B9 Tribeca 2006. Week ago started the following problems - after starting up, engine is shaking (rough idle) for a few (20-30) seconds and then it's OK. Then I got Check Engine, Cruise and ABS lights on. Diagnose shows mistake in 1st cylinder. changed spark plug, air filter, checked all connections, cleaned injector and throttle. Lights went out and engine was working as new. but the second day car had rough idle again....
