Push button start problems - please help

[latanea]

I bought the wife a 2010 G coupe 3.8 Grand Touring edition... purchase date was 7/18/2009.

(first one sold in Cincy)

She has put 4000 miles on it since new - and never had any issues with it until this week.

she was leaving work and with car in park (6 speed auto with paddles) and pushed starter (with foot on brake) and nothing...

dash lights up - but no starter spin...

she fiddles with it and it finally starts...

last night - same thing - and by now she is pissed off....

this morning - same thing - and seeing as it was in the garage - I walked out and tried it - NOTHING....

I took her to work and came home and played with it - I got it to start after I quickly kicked the brake pedal a few times.

I took it to our dealer (Columbia Hyundai - Cincy) and sat for 3 hours only to have them tell me that there is nothing wrong with the car. (they could not replicate the problem)

I explained that I thought it might be a sticky switch or something on the brake pedal assembly - and he said that it was not throwing codes - and nothing looked out of place.


I am curious if any one else has had problems with this system...

thanks

One thing I might add - the service writier said that the socket that the key fob goes into might be some sort of charger - I did not think that was the case....

any ideas on that what the pruose of that thing is?

(little socket next to 12volt plug right above shifter and below ac controls...)

I assumed it was just there to hold key - never thought it was a charger of any kind>???????

I'm having the same exact problem. It's totally random. Have you got it corrected yet?

Yes, the socket thing is there to charge the battery in the key. Mine has a green flashing light when the key is in there charging.

 

[latanea]

I looked in the manual - the key fob holder socket is just there to hold the unit while in mption (optionL)
when the battery in it IS dead in the fob the socket will allow the car to start - it does not charge - but rather works as an emergency "ID" for the car...

anyway

- no the dealer sent me on my way -

seeing that it is an intermnitent problem - and they could not get it to mess up while it was at the dealer - they can not fix what they can not observe..


(shit)

so the wife will have to try what I did - and stab the brake HARD prior to pushing button...

 

[csyria]

latanea is right, the Key fob holder is there just in case the battery of the key fob is dead or malfunctioning you are able to start the engine if you stick in the slot, it dose not charge key fob.

Having the same problem and getting worse by the week. Same thing hold the start button in and stab at the brake. sometimes it works other times it takes 5 or more minutes before I can get her to start. If it keeps getting worse will bring into the dealer.

I own a 4.6 sedan and my break pedal is rock solid when the car has sat overnight or for at least a couple hours. What you describe above has only happened to me once because I didn't push down hard enough on the pedal.

Does the couple pedal get rock solid when left for a while?

 

[latanea]

yeah when the motor is off - and the brake chambers sit - they get stiff...

that is normal...

dunno - had second dealership tell us today that they do not think anything is wrong....

???

(grumble)

 

[Squirrels]

Only after pumping once or twice does it get hard.

Any new information or updates please.... : )

Although I haven't had this problem (and I may have just jinxed myself) you may want to try hooking up an OBDII reader the next time it happens (during the problem) to see what code it's logging. There are some with the Genesis sedan forum that are having similar issues and it's throwing the code U0101pd (Lost Comm w/TCM).

My dealership was able to duplicate the problem. YEAH!!! The brake switch is the issue. It had an open internal circuit. The part number 93810-3K000 was replaced under warranty. I haven't had a problem since.

 

[latanea]

since my dealership has not duplicated the issue - they will not fix the switch (which is the problem it seems (as I predicted)...

(shit) what a hassle

Same problem. Intermittent no start a month or so ago, gradually worse. Took it to dealer and said others in this forum having same problem and believe it is brake switch. Dealer agreed. Had another Coupe in few days back with identical symptoms. Changed brake switch and no more problem. Had to order switch for me. Next day mine would not start all day. Second day still no start. Called dealer. Wrecker arrived and driver couldn't start Coupe, either. Had Coupe loaded on wrecker when driver reached in to punch button one more time. It started. Unloaded Coupe and I drove it back to dealer, careful to not turn it off. New switch had arrived. Old switch replaced. No more problem.

 

[Squirrels]

Finally decided to bring into dealer. Cumpter gave code for the switch on the brake and they changed it out in less then an hour. Have not had the problem since.

I purchased a 2012 Track 3.8 automoatic in Blue , in August 21, 2011 and was so excited to trade in my 2011 accord exl-v6 and finally get a fast and good looking car, but I have to say I am very disappointed after my whole family purchased 6 hyundais the same day I bought was supposed to be a fun car, but I have now had my Track 3.8 for a little over two months now and I am frustrated on my car leaving me stranded on the street almost every day because of the PUSH BUTTON NO START PROBLEM!!!!!!!!!!!, THE CAR IS UNRELIABLE!!!!!!, I have had the car in the dealer 3 times for them to replace the brake light switch three diffrent times, and the car still does not start, causing the car to go in to bypass mode all the time, very frustrated, My service manager at the dealer contacted the engineers and advised them of all the past repairs made on the car, and all they have to say is there is no other vendor to manufacture a better stop lamp switch, so I am screwed, waiting on Hyundai, I am the only 2012 track so far reporting this problem, so
I guess this is a isolated case, I love my car, i just want to be able to start my car every time especially in emergencies or when I loan my car to my Mom, I can rely on the car to start especially when she is alone, Hyundai needs to do the right thing and repurchase my car back and put me in to another Track with no problems since this is a isolated case, that I can rely on.

This may seem basic, but, could the battery in the FOB itself be going dead? Sorry, I misread your original purchase date. Still, It could be the FOB battery

This may seem basic, but, could the battery in the FOB itself be going dead? The battery is nearly three years old based on your purchase date.

Easy to test. Shove the fob into the dash socket each time before starting for a while. If the problem goes away then there may be a problem with the fob (battery/transmitter/etc...) or the RF antenna system in the car may have an issue.

I made this account to thank you guys and share my story:
My fiance had the same problem. She bought her Coupe 2.0T with 5k miles from the dealership. She put an additional ~1k miles on it when it wouldn't start one day. She had the key on her lap, put her foot on the brake, and it would turn on, but not start (similar to when you don't have your foot on the brake).

She has the bumper-to-bumper warranty so we called to get it towed to the dealership. She tried it one last time and it cranked right up. We attributed it to the manual saying something to the effect of "do not leave anything metal on the key fob" because she had her metal-lined purse in her lap too.

It happened again when she was at work. She got a jump and took it to the dealership. On the way we surmised that it could have been something to do with the sensor on the brakes. They replaced the battery and said they checked the alternator, wiring, and switches.

Two days later, the same thing happened. She got a jump, took it in, and they kept it overnight. The next day they called to tell her nothing was wrong with it.

Finally, it happened again at her work and I was at home so I googled her problem and came here. She printed it out and took it to the dealership. They told her that Hyundai has a "fix it the first time" policy where they're not supposed to just guess and replace a bunch of random parts. She told them to shove that policy because this was the third time she brought it in and this was a viable fix. They asked their manager and he said it was okay. They apparently replaced it with some new version of the brake switch (which may support that this is a known issue, known enough to modify the part).

Two days later, no problems yet. Thanks for the advice!
