What causes the esc light - 2008 Hyundai Sonata

It's possible that the front suspension replacement could have contributed to the ESC malfunction. The ESC system relies on input from various sensors to determine the behavior of the vehicle, including sensors related to the suspension and steering. If these sensors are not functioning correctly or providing incorrect information, it can trigger the ESC and check engine lights to come on.
In this case, I would recommend having a professional mechanic perform a thorough diagnostic to determine the root cause of the issue. They may need to check the wiring and connections related to the front suspension and any sensors involved in the ESC system.
If the problem persists even after a thorough diagnostic, it may be worth reaching out to Hyundai customer service to see if there is any other potential solution for your particular vehicle. It's possible that there is a known issue with the 2006 Sonata that is not covered by the recall but can still be addressed by the manufacturer.

A bad wheel sensor will trigger the ESC to light up. This could be caused by a wheel bearing that is going bad causing the sensor to be damaged.

If the ESC light is on, a trouble code is stored in the computer. Get the code read and then you'll have a starting place

You need to have the car scanned for fault codes to begin the diagnosis. Guessing what the actual cause might be in your case and just replacing parts is not a sound approach. Take it to KIA service or an independent familiar with KIA models.

It may just be an ESC sensor on the car that needs replacing due to failure or it could be something more significant. You might now get an ABS warning light as well if you don't have it already.

Your car is still perfectly driveable without the ESC in operation. It is just that you won't have the stability control assistance if you over cook it when driving the car too hard for the road surface conditions. If your drive sensibly for the road conditions experienced, and have decent tires fitted, you should not activate the ESC in any event (when it is working normally).

The ESC light will go out when the ABS system is repaired. The skid may have damaged a speed sensor or some other component causing both lights to stay on.

Try disconnecting and reconnecting battery to reset. If this doesn't work, go to dealer..

You'll need to have someone scan the engine and body computers to get the trouble codes. The ESC and ABS could be on because of a problem connected to the engine computer, or they could have their own issues in addition to the engine. All three systems work together.

Try checking the brake pedal limit switch located at the top of the pedal.I have a 2006 Kia sportage and the switch came loose causing the esc light to com on and the brake lights to saty on. this may not be your problem but, I hope it helps.

The brake light recall you got in the mail should fix the ESC light.

HYUNDAI IS RECALLING 532,633 MY 2006-2007 ACCENT, ENTOURAGE, SONATA, MY 2007 AZERA, ELANTRA AND SANTA FE, MY 2005-2007 TUCSON AND MY 2007-2008 VERACRUZ VEHICLES. THE STOP LAMP SWITCH IN THE AFFECTED VEHICLES MAY MALFUNCTION. A MALFUNCTIONING STOP LAMP SWITCH MAY CAUSE THE BRAKE LIGHTS TO NOT ILLUMINATE WHEN THE BRAKE PEDAL IS DEPRESSED OR MAY CAUSE THE BRAKE LIGHTS TO REMAIN ILLUMINATED WHEN THE BRAKE PEDAL IS RELEASED. A STOP LAMP SWITCH MALFUNCTION MAY ALSO AFFECT THE OPERATION OF THE BRAKE-TRANSMISSION SHIFT INTERLOCK FEATURE SO THE TRANSMISSION SHIFTER WOULD NOT BE ABLE TO BE SHIFTED OUT OF THE PARK POSITION. IT MAY ALSO CAUSE THE ELECTRONIC STABILITY CONTROL (ESC) MALFUNCTION LIGHT TO ILLUMINATE, AND IT MAY NOT DEACTIVATE THE CRUISE CONTROL WHEN THE BRAKE PEDAL IS DEPRESSED.

The stop lamp switch is used to judge if the acceleration system is abnormal. The stop lamp switch contains two switches monitored by the PCM. This is all covered at the dealer.

The stop lamp switch contains two switches monitored by the PCM. This will cause the issue you are having. It will illuminate the engine light also and cause the transmission to go into limp mode which is what's happening. Have replaced many for this same exact issue. This is what needs to be done next. The engine and ESC light come on together.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Rodos have an issue with the brake light switch which might cause the ESC light to turn on. Have the ABS system scanned, and if your car is still under warranty, then get the brake lights switch replaced.
