Sorento 2011 XM - Keyless start /intemittent issue

[Kia_2011]

My wife is enjoying our newly purchased Sorento...after about 3wks of driving we have had 2 instances where the vehicle would not start. Foot on brake, car in park....second occurence took ~10min. before car started...any ideas?

Have you replaced the battery in the FOB? Also when/if it does it again.. did you put the FOB in the cradle that is in the armrest between the driver/passenger seat? Is it just 1 or both of the FOB?

If the battery is dead or almost dead and car dosent start, the cradle is there to give it enuff juice to start the car. Only other thing I can think of is that somehow someway the FOB is loosing its pairing with the vehicle.

Hmmm...both FOB's....noticed today that brake pedal was hard...without foot on brake pressed keyless start once....twice(keyswitch) and then back off. When I next put my foot on the brake it was soft and I was able to press start...any thoughts??

I have had my Kia at the dealership for over four weeks now. They say they need to replace the Fuse box as there is an issue with the electrical relay. Problem is they cant seem to get the part. Ive heard for 3 weeks now that the part will arrive tomorrow. but tomorrow never comes. Anyone else out there having issues with not start on a push start

Not that this will solve the problem, but you don't need to step on the brake to start the vehicle. In the manual, it says that you press and hold the start button for at least ten seconds, and it will start. I've tried it and it works.

KIA 2011, How did you get the hard brake pedal and not start issue corrected. I have 2011 EX V6 with same issue. Brake will not move enough to let brake switch to operate, so push to start will activate, Thanks for your reply.

I know this is a little older thread, but I wanted to see if any of the above owners with issues ever got them resolved. We also have a 1 year old 2011 Sorento and are having this issue way too often.

Any help or advice would be appreciated.

pipallazzo, I am still having a hard brake pedal. Dealer adjusted brake linkage which provided more movement of the pedal. This provided enough clearance to activate the brake light switch. The engine will start. I am still after the dealer to fix the brake pedal issue, this only happens after the car sets over night. From what I can determine there is a leak in the brake booster system that will cause the pedal be held at it's upper position. Please let me know if you are having the same issue. Thanks !!!

Gentlemen, I got the same issue way back then and until now still occuring when sometimes I loosely push my brake pedal once and push the button start. The engine is cranking but It will not start. If you will not push the button to stop, It will continue to crank that seems not completing the starting cycle. If that's happens, I simply placed the FOB into it's slot and it starts. After that, it's starts as usual.

Reasons why happen, 1)poor FOB transmission(pairing) 2) Weak FOB battery 3)There might be high interferencing signal around you. 4)Brake pedal switch doesn't engaging properly..what else?

Note: Since then, I develop a habit of pushing the brake pedal 3 times before I push the Start Button. Seems work perfectly... Good Luck!

One temporary solution when the car wont start :

transponder being in the car : dont press the brake pedal ,press once
the start button to enter proper mode ,
then push and hold the start button for 10 seconds ,
at 11 seconds the motor will start.

I know 2 sources for the wontstart situation :

1) the brake switch refuses
to send the ok to the computer .

2) the fuse that controls the brake lights is burnt-loose- or something
is wrong along this circuit.
this fuse is found in the motor compartiment.

I have a post about this problem , when your problem get
fixed make this test : remove this fuse and see the exact problem re-appear...
it makes a perfect thief deterrent if you park for a long period...
