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.

Sonata I45 (YF - 2011+) :: Brake Pedal Getting Stuck
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.
Sonata I45 (YF - 2011+) :: Creaking When Letting Up On Brake Pedal Slowly / Lightly
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
View 3 RepliesSonata I45 (YF - 2011+) :: ESC Light Started Coming On - Brake Pedal Is Very Sensitive
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.

I noticed last night that the brake pedal was hard when I tried to start the car...then it softened up after I started the car.
does this mean my booster is starting to go bad ?
it usually feels normal and soft to the tap when I press the pedal and hit the start button.
Azera HG (2011-16) :: Stiff Brake Pedal At Start Up - 3300 Miles

View 10 RepliesSonata NF (2006-10) :: All 3 Brake Lights Activate Then Start To Blink When Step On Pedal
I just noticed it this morning. When I step on my brake pedal, all 3 brake lights activate, then they start to sporadically blink, I don't think it's a fuse problem, since the 3rd brake light also blinks, and I believe it runs independent of the regular brake lights.
What to check.. No codes are being listed, checked that with my Scangauge II already. (2006 GLS)
Sonata I45 (YF - 2011+) :: Hard Shift Roughly - Make Clunk Noise And Surge At Start Up
So, I took my 2011 Sonata SE in for service because I was having some transmission problems (18,000 miles). After starting the car and putting it into drive or reverse, the car would make a large clunk noise and surge forward or reverse. This happened only twice. I was also periodically getting some very hard shifts. They told me that they were getting an error showing a bad temperature sensor for the transmission fluid so they had to replace it. A lot of this started after the update. We will see if that fixes the problem.

87k miles with no problems ever. I was driving on the highway last night and next thing you know I lost the engine/power and all the dash lights came on so I pulled over and after the dash lights stopped kind of flickering I could not start the car back up. I tried all the tricks I read about...holding the start button in for 30 seconds, rocking the car to loosen brakes, etc and still car wont start. I have a new battery and car was just serviced last week. Oil is good. Radio and all electronics work fine. Brake light comes on when depressed but its stiff. I tried a code reader on it and its generating zero codes.
View 3 RepliesFord - Focus :: 2001 - Brake Pedal Feels Hard / Transmission Hard To Shift From 1st To 2nd Gear
Could my brake issue be related to my transmission problem? Neither are constant. Brake problem= sometimes the brake pedal feels hard, like there's no power brakes (I drove a car once. ..looong time ago. .. that had no power brakes or steering) but it will kick in after a short distance. Transmission prob= seemingly unrelated, is a problem shifting from 1st to 2nd gear. This has happened maybe a 1/2 dozen times, the first time and mostly when in heavy commute traffic and when going between 1st and 2nd gear because of the slow commute speed, but also at other times when not in lengthy slow commutes. When it doesn't shift, the odometer doesn't work (shows only dashes) and an engine light comes on (the sprocket/gear looking one). Usually the transmission will eventually shift and the light goes off.
I read that the brake problem might be a vacuum hose problem? Something about a booster? Is this dangerous? or is it like having a car w/ no power brakes? Going to have my transmission looked at this week. Read on another site about dropping valve seats on this year car. If there's a major transmission problem, I'm wondering if it's worth fixing? I changed, timing belt, water pump, front and rears brakes, tires. 143,000 miles.
Ford F-150 (2004-2008) :: Sporadic Front Brake Drag / Hard Pedal Post Front Brake Line Change
Had a lift done (Rough Country, after reading through these forums) on my 04 F150 Newer Body Style 4x4. Now, sometimes the pedal gets harder to push on until it won't go down at all and the brakes (only the front) start dragging. It goes away after awhile (my rotors are shot and I'm going to have to replace them after I figure out what is going on) but always comes back. The brake lines have been bled and I'm having a shop bleed them again tomorrow (that's what they said the issue was) just in case.

Passat (B7) :: Brake Pedal Extremely Hard To Depress
Having an issue with my brake pedal. When the car sits for long periods of time, usually overnight, the brake pedal is extremely hard to depress. I have to really press down hard in order to start the ignition. Took it into my dealership, and they actually said there was a TSB issued for something to do with the brakes. Well, evidently, they fixed it, but the issue came back almost immediately, only this time it's worse. The brake pedal firms up after 3-4 hours of sitting.
Brakes feel fine once the ignition is turned on. I was told there's no issue with driving it, but I'm not so sure I trust what I was told.
Prius (2004-09) :: Brake Pedal Really Hard And Car Slowed Way Down
I have a 2008 Prius. Had to do an 'emergency' stop. Put my foot on the brake pedal REAL hard and the car slowed way down, but not down enough. Munched the front end. Now remembering back, I didn't feel any 'chattering' from the ABS brakes. It seems like I got regen braking but never switched to the hydraulic brakes. Is that possible? Did I experience a braking failure? Or do Prius just take a lot longer to stop? I did a test stop in the rental car I have now (not a Prius or hybrid), and it gives me the ABS chatter as I would expect, with a short stopping distance.
