Check the Negative battery terminal that is connected to the ground (vehicle frame). If the frame has paint on it you need a wire brush to clean the paint on the frame and the bolt.

I have experienced it a few times on my 2012 Sonata. I found out that there is a sensor that detects the break pedal being pressed. Sometime it malfunctions and although the break pedal is pressed, it does not detect it as pressed. The solution is to get out of the car and slightly push it forward or backward. Then the sensor works again and I can start the car after pressing the break again. I hope this helps others.

Check your battery connector too! Mine was just very loose! (What a relief)

I replace the car battery and everything worked fine

My 06 sonata did that,and we changed the starter on mine and ever since haven't had that issue.just a suggestion that I thought I would put out there.

I believe it is the shift linkage / neutral safety switch getting out of adjustment. This screws up the neutral safety switch. Remove the battery and mount. Loosen the nut connecting the shift cable to the shift lever. Everything will center itself. Jumper the battery cables to see if it will start. It not, adjust the switch by loosening the screws and move it some. Try until it starts

I'm at same problem .?? Do you have any solution??

That’s why I don’t like push button start my car is a 2013 with a standard key ignition has 160k on it and never had a problem other than standard. Maintenance

i will stick to the old style key

Hi Justin, did you ever get the problem fixed ?

My 2014 santa fe does this. Had it checked many times but could never find the problem. I just slap it in neutral and it starts!

Mine did the exact same thing but it would start sometimes. I replaced the starter, problem gone.

Going through this exact thing. It feels like the battery is dead but I charged it and still nothing. When inside the vehicle it says no key found so I can’t push start. Put the key into the Fob inside the center console and still nothing. The car won’t even let me get it into Neutral to push. Going to try and jump start today as last ditch effort but might have to take it in. Dreading it becoming it’s going to be an arm and a leg for something probably extremely easy and cheap. Any advice would be great!!!

My 2012 will start if you jump it, but after it runs for about 10 minutes if you turn on the lights, heat radio anything all those lights come on one by one then the car acts like it wont cut off at all.....any ideas ive got a new battery, dont wanna change the alternator if its good. Someones said its an electrical issue.....but what?

Once the light goes red push it again and hold it for 15 seconds

Mines just now recently started doing this as well I’ve noticed mine will not light up what’s so ever any way I decided to get out of the car thinking the battery was dead went to the trunk to get jumper cables forgetting it was locked well by trying to Open the trunk it engages the car and like I got power again so I hurry back and crank it works every time so far for anyone having trouble I’ll keep y’all updated as I take it to the dealership

Those cars had a recall on that

Justin- Whatever happened with your car? I am having the same problem too now. It happened on the highway and will not start at all. Same lights are on.

what was the problem

How i fix it please tell me

When you don't press the brake pedal, you're just engaging the "accessory" function, no different than 1 click forward with a key based ignition. Just fyi

that looks like a brake switch malfunction

What happened to your car

This is exactly what is happening to my 2019 Tuscon. Only 4 almost 5 months old with 4185 miles on it. Had to reset the battery for it to start and took it to Hyundai. They returned itv2 days later saying they found no issues. For 3 days and on day 4 it won't start again. Totally unacceptable. I am beyond frustrated.

I have 2010 maxima push start , the little yellow car that pops up with the key in it is actually is the inner lock thats keeping you from starting it..the inner lock system is located just where your knees are at..so if you take your bottom panel off and look directly up you will see a metal box with a phone jack look alike cord plugged into it..what happens over time these cheap make things get James up..to by pass it tap on it as hard as you want to , to get it started..dealer ship has those parts for $500..I got away with doing this for a whole year be4 I actually had to break it open and turn the gears inside manually

It should be a slot inside your armrest to stick the key in order to bypass it

WOW!!! Talk about annoying, frustrating as well as a few more choice words...that would piss me off!!! I have the same exact car and I love it!!! Shes a black beauty!!! And thankfully I havent had any issues with her. She is also a push start. She starts right up whenever I get in to go somewhere. I have seen/heard quite a few problems with these cars and it boggles my mind because mine has been a flawless car and continues to shine 😎👍

My 2014 Hyundai sonata made me really regret getting a push start car. I have this issue a lot. Often when it does this my brake pedal locks up, nothing on the dash comes on, and the key is undetected, even after changing the battery or inserting it. I literally have to wait around for it to decide to work. When taking it to the dealership they don't know what the issue is and want to charge out the ass to find out which I can't afford to do especially if it's going to keep happening. 😔

How did u fix it

Has to ne on accessory then hold down start button...but still that didn't work for me. I tried staring in neutral and nothing I tried everything finally just walked away from the car and left it with keys in it I'm done with it

Same problem with my optima...

this is the problem I am having at this very moment!!! Did you find out what it was?

I have a 2011 sonata. They replaced my engine including the starter a couple years ago when it blew up. The starter went out 7 months later so they replaced it under warranty. Not even a year later my car won’t start again. Intermittently. Sometimes when it’s jumped, sometimes not. It starts when it wants to. Replaced battery no luck. I have it towed to the dealership for them to tell me it’s the starter again but I’m out of warranty and they want $700 to buy an autozone starter and replace it. I SAID NO THANKS. My mechanic replaced the starter with no luck. Ordered another starter…no luck. He put my old one back on and it’s starting. He said that if I press it 4 times fast it should start. He thinks it’s the ignition switch. I have noticed about 4 times in the past 6 months my dash, headlights and radio flicker. There’s a very slight flicker in the lights when the car is on but when the car is off there lights are fine, no slight flicker. Can someone help me?! I’m so scared this is going to be costly.

Mine is like that idk what to do

Mines did the same but if press the button twice and hold the second time for 30sec it turns on

My 2012 Sonata is doing the same thing.

Today I got the same thing , and the issue is electric, take off the + cable from the battery and put it back on

Same problem it started just fine until Monday now it won't start new battery.. makes a noise after that nothing, lucky today start but when got off work try again nothing

The dealership eventually claimed it was a starter issue (I don't believe them at all). I think they reset some electrical system and it fixed it. I had a complete engine rebuild done in August 2015 (which became a large recall a month later). When I got the car back, I noticed that when I locked the car, it no longer made 1 'beep' for locking the car but was still making 2 'beeps' when unlocking the car. Before getting the engine redone, it did make a 1 beep sound when locking the car. When getting the car back the first couple times with the non-start problem, it still did not 'beep' when I pressed the lock on the key fob. The problem persisted, especially in the cold. When I got it back the last time, my car did in fact make that 1 beep sound when pressing the lock. I did not consider the fact it wasn't happening as an issue, but I definitely noticed that it was fixed after the last time. It struck me as odd. They never mentioned anything about. This probably doesn't answer any questions, but I guess I don't really have any answers. Maybe it really was the starter. Good luck.

Having same problem right now

Starter

Did anyone successfully figure out what causes this problem?

Starter. That or its locked.

😍😍😍😍😍😍😍😍😍😍🎎🎎🎎

Starter easy

5 year 60000 mile warranty with roadside assistance so just call and have it towed to nearest dealer for a free fix. If it keeps happening then Lemon law.

All you have to do is stick your remote into the slot inside of the armrest. Lift the armrest and there's a slot to stick your remote in it's like a second ignition. Then your car should start!

I have the same car and I was told that the engine was locked up and the car just died on me

Means u need a new starter

easy fix!!!! i know

Easy fix keyfob battery dying....

Push button requires the brake to be pressed in order to start the car.

Why would anyone film this ...

Garbage Hyundai, get a Honda or Toyota, the car will take good care of you not the other way.

The Answer Is That Your Car is Dead. Go to the trunk and Jump it. I did the same last night. After that let it run. For a while

What ended up being the problem
