I leased my 2015 Sonata Turbo w/ Ultimate Package back in November. Experiencing flare ups between shifts in the transmission. Every once in a while, specifically when cold, I will get a slight hesitation and slip in between gears 2 and 3. It doesn't happen too often, so I'm not that concerned about it..just wanted to see if others have seen the same thing.
View 4 RepliesSometimes mine shifts nice and quick, but sometimes it also shifts soft and slowly with a slight "flare" between shifts. Seems like it shifts better the harder I drive it, but I try not to drive like that. Dealer says everything seems normal to them. Maybe it's the adaptive transmission?
View 32 RepliesWhen cool to cold my 13 2.5L Camry SE 12k miles has shifts that are 'crisp' (not meaning that is good). It I s like it rides up to an rpm and throws on the clutch and the RPMs drop by 200rpm and then she pulls into gear. No slamming but feels like a sports car driver changing gears with just a moment of that 'transition float' between gears cause by physically moving a clutch pedal. An actual noticeable shift feeling and a moment of floating 1/2 second transition. Is this 'flare'?
I guess I could just say this... It feels like it is truly 'going between gears' rather than the typical slush sliding into gear like most all automatics do.
I now have 1025 miles on my SE with the 2.4L. I will admit that I drove the car very easy during the first 800 miles. The car has always wanted to shift into higher gears way too quick even in normal mode. I was told that the computer may have been "trained" to be being a conservative driver. I am not a speed racer, but I do not drive like I have nowhere to go either. I have tried driving a little more aggressively (holding down the throttle and making it shift around 2500-3000 rpm when I can), but it still has not worked. When I make a certain turn and up a hill, the car chugs up the hill until it finally decides to downshift into a lower gear and it will finally go. If in sport mode, it does fine. I cannot leave in sport mode however because I do a lot of freeway driving and it will not shift into overdrive in sport mode, at least my car don't which I find odd??
Another problem area is when I first start out, I go up a grade on a highway. I have to literally press the pedal down about 3/4 way to even get it to speed (55 mph) within a reasonable amount of time... it was only around 2300-2500 rpm and I was almost flooring it. I pressed down the pedal more and it finally kicked into a lower gear and hit up to 3300 rpm and finally took off. Something is not right and I am not happy with my brand new car that I paid almost $19,000 for. I enjoy driving my 1991 Cadillac more than I do this new car and it is a heck of a lot faster than my Hyundai. I do love the MPG I get with the Hyundai... around 31 mpg on average versus 19 mpg on the Caddy.
I just don't know what is going on with my car. I am wondering if I need to get the computer reset or something?
I have a 2002 Hyundai Sonata (automatic transmission) that has recently been "jumping" when the car shifts between 2nd and 3rd. This happens only after the engine is "warm", and does not happen in any other gears or when I downshift.
View 1 RepliesI bought a 2010 GLS 4cyl and within the first week started having shifting issues. Initially it was only when it was colder than 30 degrees outside and would only shift harshly between 1st and 2nd. Once I had driven a few miles and warmed the car up, everything was OK. It's still an intermittent issue, but now it will do it when outside morning temps are in the 50's and 60's.
I've read the TSB for 6cyl 09's and saw a post in the Santa Fe forum that sounded identical, so at least I'm not the first to experience this.
I took it back to the dealership knowing it probably would not shift badly when they test drove it because we had run out of cold mornings. I picked the car up after they reset adaptive learning and said there were no updates available for the computer. (And also being told I had bad gas in the car. Another story for another time...)
Until it starts doing it at fairly regular intervals, there isn't any use taking back to the dealership as it's very inconvenient for me to get there.
I checked the link that had TSB's and didn't see anything for the 2010's. Also, is there any place where I could check and see when software updates come out and what issues are addressed?
Many people speaking of the flare they get; up to 1000 rpm between 3rd and 4th gear when the car is cold.Here's what I did.
Started the car. Cold as normal. Let it warm up "NORMAL". Meaning NOT for 5 minutes or anything. Just the normal 30-60 seconds like most people do first thing in the morning. Before pulling away and driving off, I took the transmission and ran it through the gauntlet.
Park to reverse:
Reverse to Neutral:
Neutral to Drive:
Drive to Manual: (Automatically starts in "4")
Manual tap down to 3, 2, then 1.
Manual tap up to 2, 3, 4, 5, then 6
Manual back to Drive.
Take it back to Park:
This whole process took about 10 seconds. I then pulled away and drove off. Temperature gauge still hadn't really moved. Total time since starting the car is probably only about 1 minute or a little more. While not spinning tires, I did accelerate "Faster than normal" just to see how 3rd to 4th would go. There was no flare at all from 3rd to 4th.
Car intermittently shifts very rough and jerky. Just took on a long vacation trip and every AM when it was cold it shifted hard them smoothed out once warmed up. Got home and now it is doing it all the time. Dealer said do the trans flush...I did it and it made no difference. Is this a common problem with this model? Mileage is 39,800...not sure I want to buy this car at lease end.
View 15 RepliesNoticed cup holders above the transmission a little warm. I have a 2011 hyundai sonata se; when I drove a regular sonata I didn't notice the cup holder getting as warm as my car.
I have also started to notice that the transmission shifts into 1st gear a little harsh vs the rental sonata as well. I did do my own transmission drain and fill with Amsoil fluid. Why its shifting like this?
Well, After reading about the weird transmission issues these cars have...mine finally started to do it. It will clunk, shake the car when it shifts and downshift for no apparent reason. All of this does NOT happen all the time. The noises that come from my transmission do though.
I can have the car in Drive and have my foot on the brake and I can hear a grinding/low power steering fluid like sound that comes and goes. Its worse when I shift from Park to Reverse though. It sounds like air being released followed by a bunch of faint grinding noises.
06 F550 w/5r110w. Truck and trans runs great then trans acts like it was shifted into neutral, rpm's flare up and if you don't get your foot out of it the trans will re engage aggressively. Changed the speed sensor on the rear axle, there are no codes, had a trans shop change the filters and fluids then change out all of the solenoids. They tell me its not a trans problem.
View 3 RepliesWhen coming to a quick stop the transmission has a shutter upon downshifting the shutters when you accelerate quick off of a stop light or stop sign. Also quick left hand turn hear a clunk coming from left side wheel. 2015 Sonata Sport 2.4L
View 7 RepliesBeen noticing in my 2016 Sport that there seems to be a lot of "play" in the transmission. Don't really know a better word for it. When I reverse out of my garage and put the car in drive, the car rolls back a bit. Like it's pausing a few seconds before going into gear. Don't want to take it back to the dealer a look a fool because it's "normal".
View 18 RepliesI recently inherited this car from a relative, I had it and two other vehicles she owned towed to my house about a week ago. The Sonata has under 1000 miles on it and I found a stack of repair orders from the dealer where she complained that the car wouldn't move or where it had been towed after getting stuck at an intersection while driving.
What is happening is that when I get in the car, with the engine cold, it starts up and drives fine. Then with no pattern or warning, when I stop at an intersection, the transmission acts as if its in neutral. It won't go into any gear, regardless of where I put the shifter. Its got the 2.4L GDI motor. and an automatic trans.
I had to tow it 5 times now. I took it to the local dealer and they found nothing wrong, no codes, and couldn't reproduce the problem. Yet when I went to pic it up, it did it a block from the dealer, I had to push the car to the shoulder at the light. I walked to the dealer, they had a tech come out to the car and by the time he got there the problem was gone. I took it home, and when I got home, I shut it off, then tried starting it and moving it again and nothing, it wouldn't move at all, no forward, no reverse. I find that if I cycle the key, on and off, sometimes the issue will go away instantly. I also never does it cold, only after driving it a bit. It has never done anything wrong while driving at speed, only when coming to a stop and trying to move again.
When it happens, the shifter moves fine, the engine revs and there are no warning lights on the dash, it just acts like its in neutral regardless of what gear the shifter is in. It doesn't creep or pull at all, there's no movement at all when it acts up and I have to drive it to get it to do it, it can idle in the driveway all day and won't do it till I take it down the road and come to a stop and try to start moving again.
Out of frustration I bought a scan tool to see what's up but as long as the scan tool is plugged in, it doesn't act up. I've been driving it for two days without it doing it. Thinking it may be just coincidence, I unplugged the scan tool, took a ride and it did it at the first intersection, I had to shut the car off, plug in the scanner to get the car back home. I called the dealer and was told that this was impossible.
I'm starting to feel like I'm on my own with this one since the dealer seems to not be able to find the issue. I am really having a hard time believing that the dealer can't make it act up but if they're plugging a scan tool in, and driving it, maybe that's why?
As I was entering a highway onramp today, the transmission stuck and didn't shift between what I'm guessing was 3rd and 4th gear. It was revving at about 5000 RPM and stayed there.
After what felt like about 10 seconds, it got its act together and shifted and the revving stopped.
So the problem is that I have a jerky downshift 3-2 and 2-1 that can be felt by everyone in the car (car pushes forward on downshift) until the car warms up. When the car is warm I can feel it slightly at times and feel a clunk when shifting down 3-2 and 2-1. On up-shifts at times the shifts are shaky from 1-2 and 2-3. I have brought this forward to my dealership as well as another one. They all performed software updates and reset the adaptive learning. However every time I got my vehicle back after this procedure I found the A/C was on full blast. So the initial drive by the tech after the reset was learning while the A/C was on. Would this be causing the weird shifting I experience while the A/C is off. I seem to notice a better shifting when the A/C is on but this may just be me trying to reason why my transmission is behaving this way. I drove other 2015 Sonata's and they have much better shifting than my car and no hard jerks on downshifts.
Both dealers have felt the downshifts and have come back and simply said "We've done all the updates and reset and learning. This may just be a normal characteristic of the car." I told them that a brand new vehicle in this day and age shouldn't be shifting poorly when compared to an older vehicle with 300,000 km (my old Honda Civic which are prone to transmission failures). They responded casually saying you can go and get a second opinion from another dealership if you like. I am furious with their responses and just left it at that. I need to know how to get this resolved and if this is indeed something I should expect from my Sonata.
I pulled into my garage yesterday and when I tried to move the transmission into Park it would not move. I tried turning the engine off and nothing would allow the transmission selector to move. I thought I would have to push something into the transmission lock slot but the only thing I had that was close to being able to fit into the small slot was the key in the FOB but it would not fit. By pure chance I happen to push on the transmission selector to the right and it moved over and then I was able to push it forward into Park. I must have pushed the selector into the sport mode when I entered the garage.
View 5 RepliesI around 1200 miles. The car would get going when i give it gas but it feels as if their was shifting lag or slipage. Only in first gear. Doesn't happen all the tho..usually happens on rolling stops... is this normal?
View 6 RepliesAny potential issues to the transmission if always shifting the gearbox to "N" when waiting at a stop light? I noticed the car idles a lot more smoother when at N so would I'm hoping to to do this regularly if it won't hurt the transmission.
View 5 RepliesThe cruise control on my 2013 works as I expected.
However the cruise control on my 2016 Sonata does not.
When driving at highway speeds (65 to 70 mph) in cruise control and the shifter set on "D" (drive) the transmission will down shift to 4th speed whenever I go down hill.
This might be intentional as a way to keep the car from exceeding the set speed, but I have never heard of this and it would seem to place more wear an tear on the transmissions.
Do the down shifting is engineered in or if it is a service problem that I need to have addressed...
The problem is that it appears the torque converter is locking up so early even right after getting into second gear at speeds between 20km/h and 40km/h. This causes shuddering/rattling coming from under the hood. If I am not mistaken a torque converter should lock up at speeds 80km/h+. I've never seen this behavior on any car before. I'm not sure what kind of damage is being done either by all this shuddering and rattling going on with the transmission. I feel that this should be something that needs to be addressed via some software update. Is there any software update in regards to this issue?
