Sonata I45 (LF 2015+) :: Transmission Won't Go Into Any Gear When Stopped At Intersection
I 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?
Sonata I45 (LF 2015+) :: Transmission Stuck And Not Shifting Between 3rd And 4th Gear
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.
Sonata I45 (LF 2015+) :: Transmission Rough / Shifting Lag Or Slippage Only In First Gear

View 6 RepliesSonata I45 (LF 2015+) :: Intermittent Vibration For A Few Seconds
After a couple thousand miles I have this intermittent vibration in what feels like the rear end being I can't feel anything in the wheel. It vibrates for a few seconds, goes away. Then vibrates for a few seconds and goes away. But even that timing isn't consistent. It could be good for a minute, then go back to every 3 seconds.
I'm way too busy to bring the car in so 2k later during the first oil change, I get the typical "dealer can't replicate". I was expecting it after I told them I do 75-80mph and they replied with "Well we can't drive that fast".
They make another appointment to have it in so they can start it cold (keep in mind I already told them it doesn't matter if it's cold as they tried to spew some BS about how the tires might have developed a flat spot overnight...) and I get a 2.0 Sport to use for the day and it does the same thing!
For anyone asking if it's the roads, it's not. My commute is 45 miles, 40 miles on the freeway at 75-80mph and half of that is on brand new concrete. I know, the new concrete could be bad but my 2011 GLS didn't do it! My wife's 2003 Saturn Ion 1 doesn't do it. My 2005 Impala didn't do it! So here I sit with a brand new Sonata that I love except for this vibration and I can't find anything online.
Sonata I45 (LF 2015+) :: HIDs Flickering For About 5 To 15 Seconds Then Stop
Both of my bulbs flicker, intermittently. They will flicker, most times not at the same time as one another, for about 5 to 15 seconds then stop. I have not yet been able to detect a pattern. The battery is fully powered and the resistors are not throwing a code so I assume they are working (I installed them to eliminate an error code and stabilize the voltage). The capacitors (or "error eliminators") I have installed do not seem to do anything.
This problem just started recently too, they never used to flicker at all. The only problem I had is I used to get a bulb out warning but like I said I got rid of that by adding resistors. The bulbs are only 5 months old.
Sonata I45 (LF 2015+) :: 2016 - Trunk Automatically Open After X Seconds If Key Fob Is Present
I went from 2014 Sonata Limited to 2016 Sonata limited. Have had the 2016 for a day now. On balance I like the changes with one exception. On the 2014 if I had Keyfob in pocket there was button underneath trunk lip I could press to open trunk. On 2016 that button is gone. Trunk is to automatically open after x seconds if Keyfob is present.
The problem is the trunk will automatically open as I walk past trunk to enter driver door. Then sometimes if I want to open trunk it never opens when I am standing next to it. I think they thought this was a cool upgrade but it is worse. I may have to turn that feature off.

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 RepliesSonata I45 (LF 2015+) :: Automatic Transmission - Jerky Downshift From 3 To 2 And 2 To 1
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.
Sonata I45 (LF 2015+) :: Transmission Would Not Move Into Park When Turning Engine Off
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.

Sonata I45 (LF 2015+) :: Cruise Control - Transmission Will Downshift To 4th Speed Whenever Go Downhill
The 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...
Camry 2012+ :: 2015 SE 4cyl - Transmission Drops To First Gear / Jerk

View 3 RepliesSonata I45 (LF 2015+) :: Torque Converter Locking Up So Early - Shuddering And Rattling Transmission
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?

Sonata NF (2006-10) :: Transmission To Hang In Between 1st And 2nd Gear
Just got my 06 3.3 GLS. Sometimes it seems to hang in between 1st and 2nd gear. No amount of throttle will make the car go or rev up until you let off and it changes gear. Then its fine. 79k miles, no cel. When i say it wont rev it will be at full throttle and engine and vehicle speed doesn't change. I just had the heater core replaced but not sure how this would relate to that issue? Someone said he thought maybe the trans needs to relearn its shift points after having the battery disconnected but not sure I buy that.

View 1 RepliesSonata I45 (YF - 2011+) :: Transmission Stopped Shifting Into 6th Gear At 70 Mph
This morning while driving on the freeway, the the transmission stopped shifting into 6th gear. This was at 70 mph. The only way it would shift up to 6th is by using the manual mode, however after manually shifting to 6th I moved the stick back over and it immediately downshifted to 5th at 70+ mph. Concerned, I pulled off and turned the engine off. After i restarted the engine, I continued to my destination and the trans shifted up to 6th on its own. The car has never done this.
