#21 of 32 2006 Hyundai Tucson ECS light problem by robare

I recently bought a 2006 Tucson and after experiencing the "ECS" light problem I read with great interest the comments posted here.
I have a shop manual for the 2006 Tucson and it clearly shows that the brake switch is a dual switch. One set of contacts for the brake lights and one set of contacts for the "ECS" circuitry. The "ECS" contacts are closed until the brake pedal is pushed. Then, the brake light contacts close and the ECS contacts open.
The reverse happens when you let your foot off the pedal.
I suspect that the ECS contacts sometimes aren't closing when the brake pedal is let up.
The switch is easily removed and it's an easy dissassemble to inspect and clean the contacts. I found the heavy duty brake light contacts somewhat pitted.
I cleaned and adjusted the contacts and put the switch back in the car.
Let's see what happens. I'll post future results.

It's been 3 days since I cleaned and adjusted the brake switch on my 2006 Tucson (19,255 miles)
So far, the "ESC OFF" light has NOT come on.
Previously, the ESC OFF light would come on and stay on even if it was a short or long trip.
The only way to shut the light off was to stop and turn off the ignition.
DUH IT's Electronic Stability Control = ESC

OK Now it's been two weeks since I serviced the switch and the E S C light is behaving normally. Now at 20,180 miles.
Definitely.....The brake switch.

I just had my Tucson into the dealer on Friday 10/3 with the ESC light issue as well. They replaced the brake light switch and said that it is a common complaint.
