Sonata NF (2006-10) :: Key Stuck In The Ignition

This is the original key that I've used since the car was new. This morning I stopped the car, shifted into PARK, and turned the key to shutoff the engine and accessories. The key turned completely as it should, but the steering wheel did not lock and the key will not come out. I messed with it a bit but with no luck. An usher walking by got in and tried it a few times, but no luck. The car will start and run fine, I just can't get the key out of the ignition.

This also means the key fob won't lock the doors, so I have to leave the key in the ignition and the doors are unlocked. GREAT!! I have an appointment with the dealership on Thursday of this week, until then I'm driving my other car and leaving the Sonata in the garage.

Sonata I45 (LF 2015+) :: ECO Transmission - Neutral At Stop Lights Save Gas Compared To Drive?

Eco Transmission. Neutral at stop lights save gas compared to Drive?

I almost feel like when I'm stopped in Drive it's actually in neutral. I'm curious if being in Neutral at really long red lights would save gas?

Sonata I45 (YF - 2011+) :: Traction Control Light Stuck On / Brake And ABS Lights Intermittently Flashing

I am the owner of a 2011 Hyundai Sonata GLS. It has approx 35,700mi to date.

Ive been apart of the forum for quite some time now. Ive been having an issue for a couple of months now with my Traction Control light being stuck on and intermittent flashes of the Brake light (as if parking brake were engaged) and ABS Lights simultaneously.

I'VE ALREADY HAD THE BRAKE SWITCH FAILURE RECALL PERFORMED. When i was having problems shifting and with my cruise control.

This all started this past winter during a bad snow and ice storm we had here in St. Louis, MO. I was on my way to work and the roads were slick with ice and snow. I was traveling no more than 15-20mph on a freeway and as i was approaching a light it suddenly changed to red and i had to slam on my brakes and make a swift right turn in order to avoid hitting anyone in the intersection. Ever since that moment, I've been stuck with these lights on in my dash.

Let me start this by saying I've done a couple of mods to my car. Hids, aftermarket remote start (professionally), aftermarket stereo, amps, new speakers all around, led lights inside, cup holder mod and led tail lights. That's all of my electrical mods.

Ive taken my car to the dealer several times for this problem. They tried hooking my car up to their code machine and they said the car wasn't communicating with machine and it was the first time they've seen something like this before.

They tried pinning the problem on my alarm and stereo. (as they usually do) They said it was a corroded ground. The dealer cleaned that up and said that fixed the problem. In actuality, it didnt. The issue still was there.

Ive had both the alarm and stereo removed to see if this were the cause my issues. NO...the problem still exists.

Here's a pic ....

Sonata NF (2006-10) :: Engine Overheating When Drive On Hot Day

When I drive on a hot day the engine overheads; it almost red-lines. This occurs mostly when I drive up long steep hills (I live in the mountains) with the AC on, but even without the AC on very long steep hills (5+ miles) the engine will overheat badly. I can go over a hill and head downhill or flat and things return to normal quickly. I can also drive with the AC on doing 0-80 mph on a flat road and everything is fine all the time.

- Fan is working
- Thermostat has been replaced
- Radiator flushed
- Engine coolant temp sensor replaced
- Heat is working

Sonata NF (2006-10) :: Jumping Into Drive From Reverse

I bought a 2009 Sonata V6 this past August. Immediately I had shifting problems. I asked my mechanic and he found the TSB. I took it to Hyundai and they took care of the TSB. The shifting problems stopped, but it is STILL literally JUMPING out of reverse when I'm going into drive. Dealer said they could not reproduce the problem.

I am a Toyota driver, and chose the Sonata based on price. So far, I am not impressed and plan to return to Toyota when this one is paid off. But, in the meantime, I want this car fixed, but the dealer acts like there is nothing wrong. I have warranty for another 25,000 miles....

Sonata NF (2006-10) :: Drivers Side Window Stuck

I bought my Sonata new in 2008, it has 55K miles on it.

This morning I put the drivers side window down, no problems, and when I went to close it, there was a grinding noise and the window wouldn't move.

I'm wondering if this would be covered under the 5/60K mile warranty?

Sonata NF (2006-10) :: 2009 - Window Stuck Open

Today I was going to wash my car and rolled my driver's window down on the way there. When I got to the car wash I attempted to roll my driver's side window back up. It nudged ever so slightly up about a quarter inch and then nothing. It had totally stopped. I fiddled with the switch and it would go back down completely but when attempting to roll the window back up it would sometimes not move at all, move ever so slightly or move just about a quarter of an inch and stop. Is it possible to just get the window up manually in order to at least block the elements? I'm at a bit of a loss as to what I should do. I'm tempted to run to the drug store and grab some packing tape to seal the window off.

Sonata NF (2006-10) :: Steering Locks Up By Itself And Wheel Stuck

My wife drives our 2007 Sonata Limited every day. Over the past year, she has complained to me a few times that the steering locks up on her when she is exiting the freeway. The wheel is just stuck after a few seconds she can turn it and make the exit. I have driven it many many times and have never experienced it. It had new rotors & tires put on and after that, it seemed to stop. That was 6 months ago.

well tonight she said it happened again when she got off the freeway but this time it was at the stop light when she went to turn. Said it was stuck and again after trying to force it to turn it finally turned. I am concerned about her driving it since it is dangerous but since it only odes it out of the blue it's very hard to diagnose. I am thinking it may be that steering sensor that controls the fluid pressure but I don't just want to start changing things since I will not know if that is the problem due to a number of times the problem has occurred.

Sonata NF (2006-10) :: Door Won't Open / Stuck On Lock Position

The lock on the rear driver side door doesn't work, it stuck on lock position and it won't open with the remote. You can't even turn the lock by hand from inside. It's like it's jammed or something. The rear passenger door lock was broken a while ago, it was making a nasty noise but still working so I had it changed but this one just stopped working.

How am I gonna fix that. I was thinking in order to fix the lock, they have to remove the door panel first, and to remove the door panel the door should be open to get to the screws. Is it gonna be stock for ever ?

Sonata NF (2006-10) :: 2009 Stuck In Park / Gears Won't Change

Huge problem. Everything was fine the first couple of times I drove today.

Tonight, when I was getting in the car, it turned on. I tried to change it from Park, but it just stuck and wouldn't move and let me change at all, even down to reverse. It's just stuck in park.

What is wrong with it? What's stuck, and what can I do to get it unstuck? Or else, I'd have to get it towed because it won't budge from park

Sonata NF (2006-10) :: Clicking Noise Coming From The Accessory Drive

I have clicking noise coming from the accessory drive on my 3.3L 06 sonata. It started off as a squeaky noise upon start up. I have since replaced the belt and the tensioner and now it is a clicking/ticking noise. It seems to be a lot worse when the car is just started and it slowly goes away upon warming up. In addition, when the car is cold the voltage light will turn on around sharp turns and steering will get hard (almost like something is putting drag on the belt). What it could be?

Sonata NF (2006-10) :: 2008 - ESC Off Light Turns On Always When Drive A While After Started The Car

My car is 2008 Sonata GLS 2.4L. Recently the ESC off light turns on always when I drive a while after started the car. It still drives fine. But I have concerns of safety issues.

I heard it's a common issue for Sonata even 2011 model. I also heard Hyundai recalls for a system upgrade because of ESC off light problem. If it's true, will the dealership do it for my 2008 pre-owned Sonata for free?

It drives fine, but anyway it could be an potential safety issue. So should I drive the car to the dealership to have it fixed? I heard may owners spent a lot of time and money but never have it fixed.

Sonata NF (2006-10) :: 2008 Limited (4cyl) Stuck In Sport Mode

So, when the 2008 Sonata Limited (4cyl) was started yesterday, the + sign by the shifter lit up (first time ever since we had never used Sport mode). The car was indeed in Sport mode and wouldn't come out of it regardless of how you moved the shifter or to which gate, etc.

Took the car to a local well-regarded auto shop today and they said when they started it up it was not in Sport mode and worked correctly. I picked it up and sure enough, the plus sign was off and the car was in normal auto mode. On the way home, the + sign lit up again and yes, it went into Sport mode again and won't come out.

Btw, this Sonata has 68K miles and has already had two full brake jobs. It has nothing to do with this issue.

Sonata NF (2006-10) :: 2009 - Starter Grinds When Shifting From Drive / Park?

2009 Sonata, 4 Cylinder, Auto. 80K mileage, runs well.

I have noticed intermittently that when shifting either out of park to drive, or drive to park that the starter begins grinding as if it is being engaged. The last few times I have jiggled the key and this stopped it.

Googled and found some folks saying it might be the ignition switch selector but am really unsure right now.

Sonata NF (2006-10) :: 2007 - Rear Driver Side Door Stuck Closed

We have a 2007 Hyundai Sonata Limited Edition. The problem started when the rear diver side door window stopped working. we took apart the door and saw that the cable was all twisted. We found the part at a junkyard and replaced it. Window worked. We closed the door and didn't think twice. A few hours later we tried to open the door and it's stuck. Both inside and outside handles move but nothing happens. The door won't open at all, what to do. We obviously can't get the door off without it opening. What may be causing this??
