Sonata I45 (YF - 2011+) :: AC / Heating Mode Not Working
Dec 19, 2016
This morning I turned on the heat in my 2014 Sonata 2.0T and there was a clicking sound coming from behind the dash. Heat is now only blowing out for the window defrost mode and when I will not blow out of the other vents.

I am taking my 2012 Sonata Limited in this afternoon because while I was demonstrating the Valet feature of the trunk over the weekend, after I closed the trunk the manual key will not open it. I can insert the key into the lock, but when I try moving it right or left it does not budge.
I did not want to force it and chance breaking off the key in the lock, so I decided to take it in. Hopefully it will be covered by warranty.
I tried both manual keys and neither worked. I also tried the keys in the driver's door and glove-box and they both work fine.
I wonder how they will get into the trunk since the seat release is also in the trunk.

Experienced an accidental shift from automatic to sports mode when attempting to "park" your Sonata? It happened to me last weekend. My car shot forward like a torpedo, doing considerable damage, not just to my car but to others as well. I have often thought it takes no effort to switch to the sports mode, but have never used it. Now I wish it were not available.

Possible to change the setting for the auto mode for the headlight to come on when it gets dark? I've always thought that they don't come on soon enough, particularly in heavy rain or towards sunset when I see many other cars with headlights on.
Couldn't find a section in the manual, but wondered if there was any undocumented tweak I could perform to get the lights to come on sooner so I can leave in in auto mode and not worry about it.

I parked my 2011 Sonata yesterday and turned it off.
This morning, I tried turning the car on, but there is no ignition. I can put in the key, turn it to accessory mode (the dash lights up), but once I turn the key further to ignition nothing happens (no noise). I don't think I have a dead battery.
My brother had this problem once before. It has something to do with the fact that the gear is not in 'P'. He managed to start it after he called roadside assistance, but I don't know what he did. The gear is currently at 'P'. I was supposed to go and get my range switch replaced today to fix this but I can't get it out of the driveway.
What I need to do to get it to start?

I cannot figure out what to do when cold weather comes and I want heat in the car. I've never owned or driven a hybrid. Looks like there are two alternatives:
Set the internal temperature setting to whatever warmth I want, disable the "Automatic" setting, and assume that outside air will be drawn in and warmed by the engine and circulated inside.
Use "Automatic" and let the A/C setting automatically run to warm the air to the temperature I set.

I just got the Hyundai Sonata SE 2013 and it's great so far. I have a question about the recycled air button. It seems to be controlled by the internal computer for different scenarios.
My issue is that when I have the air turned on and let's so that I turn it off (set to 0) the recycled air mode disables and I start smelling the outside air coming in. So I have to manually push the button to enable recycle air to close the outside vents.
Also, when I turn off the car and later start it back up again recycled air is disabled again! How can I get the mode to stay on recycled air (or the mode it was previously on) when I start the car!?

I have been driving my 2014 Sonata GLS in Sport mode with no problem. However, two days ago the engine got extremely noisy. I checked the Comfort and Normal modes - definitely no scary noise. Is this common?

I've done it before but now when I try to enter into the diagnostic mode I'm not getting anything but the typical message center. I'm holding the down arrow button, inserting the key, and then starting the truck. No diagnostic mode. Am I doing something wrong? 2011 F250.

Driving home today and all of a sudden, hot air... I stopped and turned the car off then back on, hoping to reset something. Still nothing.
It almost sounds as if I can't even hear the compressor kick on when I turn on the AC button.
Looks like I'm heading to the dealership tomorrow to see if this is still under warranty. Really upset being that this car is only two years old.

Shortly after buying a used 2013 Sonata the radio started working intermittently then quit working at all.It's the base model radio with no navigation and no reset button. I have tried disconnecting the battery, re-seating fuses and even pulling the harnesses off of the radio and it is still not working. Before replacing the radio I want to see if i can use a battery to power it up on the bench to see if the radio is bad or if the problem is somewhere else in the car.

My car is at 63000 miles and the windshield washer just stopped working and wondering if this is covered by warranty? when i press the lever little bit of liquid squirts out and nothing and when i press the lever again all i hear is the motor spinning. Also if this is not covered by warranty how much do you think the dealer will charge to have this fixed?

I'm on my third/fourth (lost count) steering column now on my 2011 sonata. This time around when my guy changed the steering column at my body shop the AC stopped working. What may have happened?

I have a 13 Sonata GLS completely stock and today I noticed that the whole right side parking lights and tag lights are not working. I changed out the bulbs and no luck. I also tried looking for a fuse that controls them and no luck. I also disconnected the battery to try and reset and nothing.

I have an ongoing intermittent problem with my exterior lighting. Occasionally, the front right amber light and the entire right rear light assembly, along with the license plate light do not work. Sometimes, if I turn the car off and on or repeatedly turn the lights off and on, all the lights will come back on. I have had the car back to the dealer several times, and they even changed the light switch on the steering column, but the problem still comes back very intermittently. I have blue LED's light bulbs for the license plate and wonder if this could be the problem. There are no codes being thrown according to the dealer. I searched this forum but didn't see any results.

My girlfriend's sonata was heating up. I stopped to check the coolant and saw it was all gone. I refilled it just 3-4 weeks ago.
I've checked the most probable stuff;
-There is no white smoke coming from the exhaust
-The oil looks and smells fine
-The colour of the coolant hasn't changed
-I couldn't find any leaks (looked with a flashlight for a few minutes with the engine running, there were no obvious leaks)
I really can't find what's wrong with it.

I have a 2011 Limited Edition Sonata that I had for 4 years now. My audio system completely died. Does not turn on, thus no sound. Buttons don't work either.
On top of that, the display screen (that shows what track/radio station is playing, and clock) is dead as well. I checked the audio fuse, and it looks fine (U shape).
Before both went completely dead, it seldom came on but would die on me again. Now gone for good.

So, I am sitting at the dealership waiting for my car to get worked on. The door lock on my driver side isn't working.

About a year ago I was driving along and ran into some traffic. A few minutes later I noticed the AC stopped working, (it was about 85F out), and then I noticed that the engine temp was getting much warmer. Had never seen this before. The car had about 70k miles on it.
Turned on the heater and was able to get the engine temp down. Immediately took it to my local mechanic, who checked that the compressor was running, but was unwilling to tackle this diagnosis and recommended I take it to the dealer.
Took it to the dealer the next day and they diagnosed a bad compressor which they replaced for $1200. However the very next day after I picked it up the very same thing happened. Engine overheating and the AC turns off.
Pretty disappointed in this - I expected the dealer to be able to fix this, especially for $1200. So I left it with them for a week, and still they were not able to diagnose or duplicate the problem. Asked me to come in when it is happening, but since they are about 30 minutes away and it only happens once in a while I gave up on that.
However, ever since then it will occasionally have the same issue. I can usually resolve it by parking for a while, or by turning on the heater for a while. The AC does work most of the time, but of course this problem usually occurs only on very hot days.

So it's happened a couple of times already when the temperature has dropped below 20 degrees my subwoofer stops working until the temperatures come back up.
Is there some sort of protection I should know about because I skimmed through the owner's manual and didn't see anything about it. Seems to work perfect what's the temperature back up later.

I no longer have any sound from any device or output. Stock NAV unit and I can't figure out why I wouldn't have any sound. This NAV unit sucks. It is so outdated that it doesn't even know the right time!
