Frequently Asked Questions

Is ESC the same as traction control?

No. Traction control prevents wheel spin during acceleration, while ESC helps maintain directional control during turns and emergency maneuvers. ESC includes traction control as one of its functions.

Is ESC required on new vehicles?

Yes. Since 2012, all new passenger vehicles sold in the United States are required to have electronic stability control as standard equipment.

Can I still drive without ESC?

Yes, but with reduced safety in emergency situations. ESC significantly reduces the risk of rollovers and loss of control. Drive more cautiously until the system is repaired.
