Sonata I45 (YF - 2011+) :: 2014 - Random Squishy Pedal?
Jun 25, 2014
I've finally logged about 3000 miles into my 2014 Sonata. In the last few weeks of driving, I've noticed during stop and go traffic, that initial stepping on brake pedal decompresses kinda weird. It's almost like its too squishy on the initial few mm's of stepping on it. It seems to go away after pumping the brakes after i turn off the car. But it comes back randomly, sometimes on short drives, mostly noticeable in traffic where you brake more than usual.
I brought it to a hyundai dealership to get looked at initially but the service manager played with it and didn't notice anything out of ordinary so he did not request it to be serviced. But since it came back and starting to annoy me more and more.. i need to drop it off and have it looked at. I haven't even gotten my first oil change either.

Over the past 4 months I've had the brake warning light, the one that comes on when you press the parking brake on, come on randomly. In each occasion turning the car off and then starting it back up clears it for the rest of the day. I had it happen 5 months ago, a couple months ago, two weeks ago on new years and then this Saturday and Sunday. Took it to the dealer today and it shows no codes but they managed to get it to come on once. They think its an electrical issue which makes no sense to me.

So I started hearing these random squeaking noises coming from the front suspension its what it sounds like. This only happens thou when i drive up into a drive way that is slanted. Or any kind of slow making slanted turns (~5-10mph)
I'm not 100% positive but it sounds like the suspension because it only makes noise when the car moves a little when ever i go up a drive way.

So, I have had this weird incident happen a couple times. The first time it happened was probably a month or so after getting the car (2013 Sonata 2.0T Limited). I was parked on our driveway, and it's on an incline. I started it up, but the brake pedal was super hard to push down. Once the car started, everything felt fine, and other than a casual "Huh, that was weird." I didn't really think anything of it. Have been without incident for months.
Then today, it happened twice. Parked in the same spot, started the car fine this time, but I went to turn it around in the driveway and almost took out our shrubs because I went to brake and the pedal was stuck. Pushed down really hard and got the car to stop. Put it in park, and tested the pedal a couple times... everything was fine. Was nervous, but took the car anyways. Happened again in the afternoon. Got out of the store and thought I was going to be stranded in the parking lot because this time the pedal was stuck and at first I couldn't start the car. Luckily, it eased up when I pushed down hard and it started, then all was fine again.
I have done a little looking and saw vacuum booster and master cylinder mentioned for possibilities, though no one's experience that I have seen sounds just like mine, nor did I find any that are Sonata YF specific. I already got my switch recall taken care of, so this is something different. Only 7,000 miles on the car. Gonna bring it in to the dealer this week, but just wanted to crowd source opinions in case they can't replicate the problem. I hate feeling like I can't trust my vehicle... especially when it's almost brand new.

I recently purchased a 2011 Sonata GLS with a manual transmission--it has a mere 15k miles on it. I'd have to say that after driving it around for a bit I really don't like the gas pedal or the clutch pedal as compared to my old Honda, and my friend's new VW. The gas pedal is super sensitive--I feel like 90% of the throttle is in the first 10% of movement. I'm traveling at 60 mph and it feels like the pedal is only depressed 1/8 inch.
It's kind of the opposite for the clutch pedal. It grabs fine, that is, I can feel the engagement point perfectly, but there is so much travel. I feel like I lift my knee to my chest and have to push the clutch through feet of travel. More literally though, I can't just do most of the work by rotating my foot on the heel--I have to lift my entire leg. I prefer cars with much less travel and think the Elantra was pretty good in fact.
I don't have an eco mode since it's a manual so that rules out desensitizing the gas pedal by those means... Is there any way to reduce the sensitivity of the gas pedal, and to maybe reduce the total overall travel of the clutch pedal? It has to be reliable and safe..

I recently drove to work last week and the downtown roads suck, ever since noticing this it seems like my brand new sonata is very bumpy. Its like now I am noticing all the bumps. Tires seem to make a lot of noise too.
Also when accelerating it seems like i can feel it in my foot on the gas pedal. I would say like vibration but not a vibration if that makes sense.
Any sonata owners notice when they have their foot on the gas pedal its not so smooth. Can you feel the engine working through the pedal?
This is a brand new car with less than 2,000 km on it.

I tried to turn on my car, and the brake pedal was hard and the car wouldn't start. I did a search on the forums regarding the brake light switch. I tried the 30 second hold the start button, car would not start. Radio/lights works fine so I don't think it's a battery problem. My g/f said she can see all of my brake lights turn on when I try to depress them. I'm kind of a lost. It was working fine earlier this morning.

I have noticed that anytime i leave the car parked for more than 5 hrs or so, when i get in and put my foot to the brake pedal to start, the pedal feels very hard... as tho someone sat in the car and pressed it several times.... So great force is needed to mash the pedal to start the car... After it starts the pedal gets nice and soft as normal... Is this normal?? Or should i get it checked

I am experiencing a hard brake pedal about every other day if the car sits overnight. I know I am not depleting the vacuum supply before I exit the vehicle by pressing the brake pedal. Some mornings the pedal is very hard and barely moves and other mornings it's normal. My brake booster vacuum check valve hose assembly was replaced to try and fix the problem but it still does it. I also know my electric vacuum pump works correctly. Is it normal? Do I have a small leak in the brake booster vacuum diaphragm? I have no other brake feel issues.

Have a 13 Sonata Limited 2.0t and for some reason it won't start.
Also brake pedal is extremely stiff. Tried to push start button several times while pressing brake, and dash lights just blink several times.

I have a 2013 sonata gls and I bought it new, it only has 4,000 km on it. I don't know if this has always happened and I am just noticing now or just all of a sudden occurred but when I was stopped at a red light today and I had my defrost on, (heat fan on) it felt like my gas pedal there was a slight pulsation that I could feel. I also noticed earlier in the summer when the ac is on it seems like the car pulsates as well or the engine just sounds rougher. It seems to go away when the ac or heater fan is on 0. Is this an issue or serious problem? Why this is occurring?

Had this issue with my Kia Optima 2013 pertaining to the brake pedal, now with my 14 Sonata Limited. When in stop and go traffic, parking lot driving, or pulling into the garage that requires a lighter touch on the brake pedal, the pedal has a creaking feel to it, like when closing a creaky door. I can make this happen of course when I push the brake pedal slowly with my hand. This also happens when letting up on the pedal slowly/lightly. Kind of annoying, but the brakes work just fine and dandy

A month ago my ESC light started coming on and the dealership replaced the brake pedal switch per the recall.
Here in the last week or so, I've noticed the brake pedal is very sensitive now and will sometimes stick causing the brake lights to say on after the car is turned off.
Pushing on the pedal just a little bit (pushing down maybe less than 1/8") will cause the brake lights to turn on and also kick the cruse control off.

Ive got a 2011 Sonata GLS with 111k miles. I purchased the car new. For the past several months the brakes make a crunch or creaking sound when the pedal is being pressed OR released. The funny thing is it only happens when driving forward. When I apply the brakes while reversing, the brakes are silent. I did a pad slap at 68k and have taken everything apart, cleaned and re-lubed to no avail. The sound can be heard at the front wheels when someone else works the pedal while the car is parked. Pads have about 50% thickness. Pads? Calipers, master cylinder?

2014 Sonata had issues with the driver and passenger seats only getting warm? We just bought the car and the seats never get hot. The seats are warmer when I get in the car at the end of the day than they are when the heated seats are turned on.
