Don't recall exactly how long this has been going on, maybe a month. Between 20-45 mph, car sounds like it should shift. It finally does at 45 and all is well. But when I am in a 35 mph zone, the whining noise is scary. Is this serious?
View 44 RepliesMy son has a 2007 sonata v6, daughter has one too. Both have about 130K miles, and both developed slow coolant drip leaks. I took off both hoses on both cars, cleaned the crud from the housings and replaced with new hoses and clamps. Problems solved in daughter's car, not so in sons car. I note that it looks like the area below the thermostat housing is wet - and thought that was from the crud/hose situation. But he is still losing coolant, even more now that its getting colder at night, and I's sure its not the hose connection anymore.
The car will generally NOT leak when hot, only as/when it cools off. I.e. puddle in the morning situation.
Looking at the diagrams, it looks like that "housing" is really a connection to the crossover pipe, heater hoses, other stuff (throttle body heat) and also contains what looks like a temp sensor.
I suppose any of these are possible, but my first thought was either a leaky temp sensor (or possibly loose) or something more serious like a cracked housing, leaking o-ring, gasket etc.
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.
View 12 RepliesJust curious, in comparison to other vehicles, does it seem that the rear window defrost works pretty slow in your Sonata? I park outside and notice it is slower than I would like for it to be in the morning. Heated mirrors work great.
View 9 Replies2007 Sonata GLS - I4; 55kmiles ... I plan to sea foam on my Sonata as it continues to have slow acceleration and poor mileage. Looking for a picture of the Brake Booster or Vacuum line? I want to make sure I am pouring it in the right place.
View 3 RepliesWhen I'm driving and get above 50-60 I will get the Check Engine Light. Check the codes It shows 6 ---300, 303, 306, 300, 303, 306. When I slow the car down it is running rough, almost like it has a miss.
I reset the computer while this is going on and the engine smooths out and it runs correctly until I keep my pedal down and then it kicks the exact same errors.
Here's strange part number one: Once I get down to about a gallon or two of gas in the car everything seems to run fine. I have plenty of power, no codes and the car runs fantastic!
Strange part number 2: Very occasionally When I get in the car in the morning to go to work, the car is a bit difficult to start. When it finally kicks over, it is immediately running rough. resetting the computer with the engine running does not seem to stop the rough running. If I turn off the engine and let the car set for a bit it will start and run fine, with the exception of the first problem mentioned in this thread. There is no code while it is running rough, but when the Light kicks on as per the first issue mentioned, I have an additional code -- 335. This car has been excellent up until the last few months when this issue developed.
The driver's side power window is so slow to be put up. I think there is something wrong with the motor.
View 8 RepliesI have a 2006 Hyundai Sonata that squeaks when I turn left while in motion. It squeaks regardless of the degree of the turn but is more noticeable at slower speeds. The squeak isn't a screech so I don't think it's a belt. it isn't a grinding noise either. More like a "squeak, squeak, squeak." Seems to squeak with the rotation of the tire.
View 6 RepliesThis is on my 7.3PSD. I've observed that the 1-2 gear shift drops about 1,000 RPMs and takes a good half second or longer to do so when given a lot of accelerator pedal input. And then the 2-3 shift is a very quick and harsh shift.
If I am accelerating gently the 2-3 shift is as unnoticeable as the 1-2 shift is quick. Is the slow 1-2 shift causing the trans to protect itself and affecting the 2-3 shift? And if so, what do I do to resolve all of this? I changed the trans fluid a week ago and there is no change.
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?
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 RepliesOk, So my car wont come out of park unless you do the manual override. I recently put a new battery in the car and accidentally put it on backwards. I was lucky enough not to burn the ECU as the car starts and still drives but the ABS and ESC lights are on along with the BRAKE light.
View 16 RepliesRecently my wifes 2009 Sonata limited has started having a hard "clunk" when braking. It feels like a hard shift from 3rd to 2nd (or 1st?) during deceleration. Only really occurs when moderately cold and only during the first 10 miles or so of travel. What I should check?
View 4 RepliesI have a 2010 Sonata 2.4 with 63k miles and auto trans. Just recently I have noticed a single soft click when braking, just before the car comes to a dead stop. I can hear the click and also feel it in the gearshift.
View 4 RepliesI have a 2006 hyundai sonata, which has possibly the worst designed cup holder of all time. Because of this awful design flaw, I stopped my car at a light yesterday and some of my coffee spilled into the gear shift box. Now when I am in regular D, it appears the car stays in 1st gear. This sonata also has the option of pushing the stick to the right so you can manually shift gears.. I think it's called sports mode or something. When I try that, I can shift it up to 2nd, but I drops right back down to 1. I left it overnight, hoping it was just some wet electronics and would dry, but this morning the problem persists. Not sure if there's a fix for this, if I should take it to a transmission place, or just my regular mechanic. Someone suggested contact cleaner, which I might have I just have to look.
View 10 RepliesI think the gear shift letters (P, D, N, R) are supposed to be illuminated on my Sonata, so there must be a light bulb out. Need to confirm that there is a light under there and tell me how to replace it?
View 2 RepliesI am now getting a grinding noise when I shift from first to second gear. It sounds like the two metals rubbing each other. Its not happening all the time, but for the past two days a bit frequently
I had reported this grinding noise when I turn left a month back. Was thinking because of my worn out tyres, but apparently not.
I had to stop quick today. My ice water spilled into the gear shift lever. A mile down the road my rpms went up high and the car barely moving.
2006 Hyundai Sonata...
Situation is I have 2016 F350 that when cold, seems to have shift problems between 5th and 6th gear, where the engine revs between the gear shift under light acceleration. Once warmed up, doesn't seem to do it, 4th to 5th might be a little slow or maybe just my imagination.
View 14 RepliesMy 82 f150 4x4 302 c6 trans is acting up. My c6 is slow to shift into any gear when I shift the column shifter, after a moment it jerks into gear, also it doesn't seem D is doing anything but all the other gears seems to function manually or auto.
Fluid level looks ok, maybe a little high on the dipstick. I'm going to check the modulator and do a fluid/filter change but looking for a link to the band adjustment screw ?
2003 Explorer tranny. 4.0 V6, 213km (133 miles)... Biggest concern is 4-5 upshift shudder, no rpm rise, just a shudder and slow shift. Slight shudder on 3-4 too, I think. Some online reading points to torque converter failure.
Other symptoms: sometimes slams into gear when shifting out of park, other times it feels like there is no fluid in converter when first put into gear, especially after sitting a day or 2. (my truck does the same thing, but that's after sitting 2-3 weeks at a time)...
