Exclamation ESC off light is on

Hi all,

My car is 2008 Sonata GLS 2.4L. Recently the ESC off light turns on always when I drive a while after started the car. It still drives fine. But I have concerns of safety issues.

I heard it's a common issue for Sonata even 2011 model. I also heard Hyundai recalls for a system upgrade because of ESC off light problem. If it's true, will the dealership do it for my 2008 pre-owned Sonata for free?

It drives fine, but anyway it could be an potential safety issue. So should I drive the car to the dealership to have it fixed? I heard may owners spent a lot of time and money but never have it fixed.

Expect for your answers. Thank you guys!

Scan it, see what code is recovered.. go from there.

You'll want to look in the PCM, TCM ,ABS/ESC modules for codes

Is there a time frame when the issue started? Warranty wise that is. Original owner of an 09 Sonata, that has the issue when I go a certain distance above or below sea level.

typically this issue is caused by a faulty brake switch. if its bad it can set an esc light and even cause the brake lights to not illuminate while stepping on brake pedal. very common on all hyundais

Update ~ Got mine fixed today under-warranty. If there was a recall I would think it wouldn't matter who the currant owner of the vehicle is.
