Question about 2006 Hyundai Sonata
The dash lights for the "ESC Off" and the ABS just came on. Just driving, no indication of any problem. I have about 30k miles on the car. Anyone know what is going on?
I had the same problem at 35,000 miles. I would be driving and suddenly the ESC Off Light would illuminate. It would disappear if the car was turned off, only to reappear after a few miles of driving. It turned out to be a faulty "brake light switch."

My 2006 Sonata does this frequently. I just had the brakes repaired (pads, calipers, rotors machined) four days ago, and the light came on last night and then again this morning. I was told by the dealer's service department that it would have to be checked, and that the ABS brakes don't have much to do with the regular brakes.
Also, the ESC button only turns on the ESC light, not the ABS light.

Had the same problem with the intermittent ABS/ESC light. Took it to the dealer at 35,000 miles and they replaced the steering wheel position sensor under warranty. 30,000 miles later and the problem has not reoccured.

I had a similar problem. At first they couldn't figure it out - they tried replacing this and that.
Finally, Hyundia released a fix for this problem which involved trial and error replacing of parts until the problem goes away. Replacing the accelerator did the trick and my car has been great ever since.
I did not have to pay for any of these repairs. It is covered by Hyundai's warranty, and I didn't even buy my used car at the dealership.

Is there any chance you accidently hit the button? There's a button on the far left of the console that turns Electronic Stability Control (ESC) off, and that may be what happened.
If there's no chance of that, then try the old battery disconnect and see if it happens again. Then the dealer may be your only option unless someone else has an idea.
