I 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 2008 Hyundai Sonata GLS. Recently there has been a squealing noise coming from the pulley on the power steering pump. I would start when the car was cold but then go away when the engine warmed up. Lately it is squealing continuously. It does not get more intense when I turn, it just seems to be there constantly now. If this is the pump or just an idler pulley?
View 4 RepliesRecently my 2006 2.4 L encounter auto transmission jerk intermittently with P0734 and P0765(bad D shifting solenoid. Change the bad solenoid and the problems still occur. Later check all the wiring as per hyundai TSB and all seems to be ok. Then an error code appear that indicate bad ATM relay (auto transmission module). I interchange the suspected relay with the horn relays and the problems resolved. I did check the relay coil which is ok but the mechanical contacts is badly corroded that results in some resistance that causes the 12v supply to the Solenoids to be affected. (the relay is situated in the relay compartment next to battery).
View 6 RepliesThe shifting in my Hyundai Sonata 2009 Limited V6 is horrible, having issues with shifting such as a hard jerk from 1st to 2nd when car changes gears driving. It feels like it is pulling back when the car changes into 3rd gear oh and you can forget trying to go uphill. It is completely horrendous it is shifting always up to 3000+ rpms struggling to make it uphill. Any way to achieve a smoother shift and also towards the uphill thing.
View 4 RepliesMy windstar has for a while been making moderate/slight jerks when stopping. It tends to happen typically just before coming to a complete stop, although sometimes it happens during low-speed turns when coasting (also sometimes have the issue where it shifts downshifts harshly after a "sweeping turn," as mentioned in one of the windstar TSBs). The RPMS don't appear to visibly drop when it occurs (although the tach in the 'stars seems a little slow sometimes). The only trouble code present is P0133 for the Bank 1 downstream O2 sensor slow response.
Also, it tends to worsen when the car is warm. The jerking is less severe when the engine is cool, and tends to worsen after the car warms up. Also it sometimes almost feels like the jerk occurs in two stages. I do not believe it is the TCC solenoid failing to disengage, due to the fact that it even happens if I get up to 15mph for a hundred feet, and then stop.
Probably unrelated, but the car also tends to run rough for 10-15 seconds after starting the first time if left sitting for a few days.
When I am driving about 40 in 5th gear and let off the throttle, there is a slight jerk in the engine. Is it a loose motor mount?
View 4 RepliesSometimes when I go into reverse it feels like it pops into reverse and it doesn't go into reverse smoothly but sometimes it does go into reverse smoothly.
View 10 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?
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?
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?
View 6 RepliesI bought the car about a week ago, whenever the auto tranny shifts gears there is a slight jerk that old honda autos are known for, my wife's car is a 01 celica gt which I bought 2 months ago and went through castrol import ATF 3x drain n refill method suggested by honda for their auto trany, I attempted the same thing in the gts and the shift jerk went down a little but not by much, the gt auto tranny is so smooth I can't even tell whenever it shifts up or down other then high rpm engine noise when it gets there. Is it the engine being much more powerful then the gt to cause that jerk? Should I try a different fluid? Need to know if theirs is smooth across all gears in any rpm range.
View 4 RepliesI have a 2000 Corolla CE I bought recently that had 45K miles on it (it has a 4spd auto with O/D).
When accelerating from a stop, I usually take it very slow and I notice that there is a slight jerk most of the time.....it's sort of like I can feel the gears engage. This doesn't happen all the time and it doesn't seem to happen if I accelerate fast.
I did a transmission drain & fill with Royal Purple MaxATF (the drain & fill was only once).
1) Is this normal for this transmission? Also, is there a "pan drop" for this transmission? The mechanic only removed the drain bolt...he did not do the pan drop.
2) During my work commute, I'm in a lot of rush hour traffic where it moves for short distances at 5-10mph. It will shift from 1st to 2nd a lot of times...is better to just put the car in 1st (L) gear? My mechanic said no because it will heat up the transmission faster.
Had a slight shutter or jerking feeling in their LS, sort of like the rotors are warped, when they slow to a stop from 40+ MPH? I just cannot make the car stop smoothly no matter the amount of brake pressure I apply.
I can 100% eliminated the issue if I shift the car into neutral before I slow down. So it has to be the the transmission not downshifting smoothly. Done it from day one. I even replaced my rotors and brakes so I know that isn't it.
About three weeks ago I noticed a slight shudder in my 2008 Ford Taurus with app. 75,000 miles (automatic). It did not come from the steering wheel, but the car itself seemed to be shaking, but only slightly. Like someone who's had too much caffeine holding out an unsteady hand kind of shudder. It was going in for an oil change anyway, so I had my mechanic check it out, even thought the shudder was gone the next day. It came back, for a few moments while the mechanic was driving. He couldn't tell what was causing it, but said not to worry.
Two days later when I was in the car for the first time that day the car jerked when I put it in reverse out of park. I checked the transmission fluid, and, sure enough, it was about a quart low. All symptoms went away. I took it back in to double check that there was no leak and that everything seemed in good working order. The car was given the all-clear.
Then this week the shudder returned, again, only sometimes. It doesn't seem related to temperature, distance driven, or weather. And the maddening thing is that it only does it sometimes. I checked the transmission fluid again and it is still in the safe zone.
Two days ago, after being parked overnight, the car shook very noticeably for about ten seconds the first time I switched it out of park, first into reverse, then into drive. This was different to the other shudder (I know, seriously). This was a shake, like the bass in a super strong stereo was cranked. Then it stopped and the car drove just fine. I parked it for twelve hours then switched the gears again. Nothing out of the ordinary happened.
Today it had no issue when I first switched gears, but while I drove (for about a half an hour) that original slight shudder was there. This time at all speeds, not just low ones. I went where I needed to go, drove it again about four hours later and it was fine. No shudder, nothing and this drive went through road work with stop and go traffic as well as some time on a highway at speeds up to 55mph. I drove it another time after that, and again, no symptoms. Finally, I drove to the store. The shudder had returned. I parked, shopped for about 15-20 minutes, returned to the car, and it hesitated to accelerate as I pulled out of the spot. It did not jerk or seem to try to catch up. It simply delayed, but accelerated smoothly.
I parked again and let it rest for about 10 minutes, started it up, and no trouble at all. Even that weird shudder was gone. I think this car is toying with me. I'm taking it back to the mechanic, but the trouble is that it doesn't always have these symptoms. I drove it Thursday on a two hour trip and back again with no issues at all. This might make it difficult for the mechanic to diagnose, but at least it's a guy I trust. There are no warning lights on, no smells (unless they are faint as I don't smell things well), and no strange sounds.
2006 Sonata 2.4. A couple weeks back I posted about how my engine is making a slight ticking noise. It makes the noise consistently. I recorded a video of the noise. What it could be. Here's the video: [URL] ....
View 14 RepliesI have a 2006 hyundai sonata 3.3L V6. Only happens on a cold start. I'll start the car and it won't tick while at idle. But as I drive away ill hear it for maybe about 2 mins only maybe in first gear until the car slightly warms up and then it's gone completely.
View 30 Replies 2008 Sonata 2.4L ... I have an issue, hopefully minor, but when I drive over bumps I hear a slight rattle in the front suspension. My first guesses are either a sway bar, struts, or tie-rods.
My second issue is the steering wheel isn't centered. Best way to describe it is if you draw a line dead center on the top of the wheel and remember that spot, when driving straight it's about an inch or two to the right.
I have a 2006 Sonota and I'm getting a slight rub feeling when I turn the steering to the left or right. What should my concern be on this and what steps should I take to solve this problem?
View 3 RepliesABS, Brake, Traction warning lights display and chime sounds when car is started in the mornings. These warnings disappear after car is parked for at least half an hour and then re-started.
They will come on then intermittently while going over a small bump, or sounding horn or turning on wipers. It's like the car is haunted.
So far the dealership has replaced a front speed sensor which solved the problem for a couple of weeks. Yesterday I returned it to the dealership with the same problem and they diagnosed it as a poor battery cable ground and declared it fixed. This morning the lights and chime were back on.
The power steering feels loose & less responsive while lights are activated.
