ABS/ESC Off light?

Asked by Rob Dec 11, 2014 at 02:40 PM about the 2010 Hyundai Sonata GLS FWD

Question type: Maintenance & Repair

The ABS/ESC off light are one together on my 2010 sonata, since yesterday morning.
Thought it was the usual brake switch recall. Took it to the dealer made the switch.
Lights still on. That was yesterday. They'll occasionally go off for about 1 second
randomly and then come back on. Hit a road plate pretty hard this morning and heard a
bad scraping noise. Took it in for an oil change I needed anyway, and lo and behold
bad bearing. So $500 later I have a new bearing and hub. Thought the bearing would
fix the abs problem, as it was most likely messing with the wheel speed sensor. Also
the mechanic told me the new hub has a ring for the ABS which was totally ground off
on the old one. But repair done, lights still both on. Their generic scanner wouldn't clear
the code, so took it back to the dealership and cleared the code there. Came right
back on immediately. Any ideas? Car drives and handles fine. Regular brakes are
good and brand new pads and rotors in August. What else could cause the ABS +
ESC off lights to be steady on, and not fixed by either the brake switch recall or fixing
a bad bearing?

I have the same problem abs/esc light both on and will not turn off. So I took it in for the brake switch recall repair. After the repair the same lights still stay on, I was told I needed a new left front abs sensor switch. They did not have one in stock. Will cost parts and labor around $160.00 so I will have to wait for now.

I'm having the same problem too. I have even taken the car to Hyundai in response to a recall on the abs. Still the ESC OFF light just comes on and the break holds abruptly. Could anyone give a heads-up.

This has to be some sort of glitch in the computer my 2009 Santa Fe with only 30,000 miles is doing the same thing with the ESC and the ABS light just came on today for the first time, usually the TPMS light comes on and off sporadically this is something that Hyundai has never fixed because I had a 2007 Sonata and the TPMS light come on and off sporadically going to pull the battery cable off for about a minute or two and see if the computer resets

Tbh I dont think even hyundai knows why it does it, could be because they are cheaper quality then other types, or maybe it was Hyundai's way of getting their riders to continuously replace parts...

Bulbs. Check all brake lights and tail lights.

Checked tail light bulbs, one is out, curious to see if ABS and ESC lights go off once bulb is replaced.
