Sonata I45 (YF - 2011+) :: Traction Control Light Stuck On / Brake And ABS Lights Intermittently Flashing

I am the owner of a 2011 Hyundai Sonata GLS. It has approx 35,700mi to date.

Ive been apart of the forum for quite some time now. Ive been having an issue for a couple of months now with my Traction Control light being stuck on and intermittent flashes of the Brake light (as if parking brake were engaged) and ABS Lights simultaneously.

I'VE ALREADY HAD THE BRAKE SWITCH FAILURE RECALL PERFORMED. When i was having problems shifting and with my cruise control.

This all started this past winter during a bad snow and ice storm we had here in St. Louis, MO. I was on my way to work and the roads were slick with ice and snow. I was traveling no more than 15-20mph on a freeway and as i was approaching a light it suddenly changed to red and i had to slam on my brakes and make a swift right turn in order to avoid hitting anyone in the intersection. Ever since that moment, I've been stuck with these lights on in my dash.

Let me start this by saying I've done a couple of mods to my car. Hids, aftermarket remote start (professionally), aftermarket stereo, amps, new speakers all around, led lights inside, cup holder mod and led tail lights. That's all of my electrical mods.

Ive taken my car to the dealer several times for this problem. They tried hooking my car up to their code machine and they said the car wasn't communicating with machine and it was the first time they've seen something like this before.

They tried pinning the problem on my alarm and stereo. (as they usually do) They said it was a corroded ground. The dealer cleaned that up and said that fixed the problem. In actuality, it didnt. The issue still was there.

Ive had both the alarm and stereo removed to see if this were the cause my issues. NO...the problem still exists.
