While I have never heard of this type of problem it is fairly clear that the ESC has malfunctioned in some manner. The function of the ESC it to maintain an intended path when the car is headed into..for whatever reason...an "out of control" scenario. It seems to me that the car and its path is being altered when there is no reason to do so. Since ESC uses a whole bunch of sensors and the ABS to detect and control this "out of control" path any one or more of those could be the culprit. The dealer has replaced at least one of those sensors the YAW sensor but clearly another sensor has momentarily burped causing the ABS to engage in an attempt to fix something that isn't broke (your car isn't sliding out of control). It is a safety issue and for there to be no record of a fault code in the memory is unusual. BUT when your dealer says they cannot duplicate it they probably are telling you the truth since it is an intermittent problem. It would probably be better for your/and others safety to have them keep the car until either they CAN duplicate the problem and or until it generates a fault code so they have somewhere to start. Probably a loaner can be supplied until a fix is done.

Funny you should say that. The guy at the dealership made the comment as to what I wanted him to do because he saw no reason to keep my car.
 
I have decided not to drive on any highways to avoid high speeds and in so doing have had to add 20 minutes onto my commute to work.
 
I called the service manager today and he said that his district rep wants me to bring the car in so that they can take all the tires off and "manually" (what did people do before they had computers?) inspect every part and all the sensors. I pray they find out what is wrong so that I can truly "drive" my "new" car. They can't get me in until Friday...
 
Thank you very much for your response and depending on the outcome after the inspection on Friday, I may have to insist on a loaner.

Wouldn't turning ESC prevent it from misfiring?

Nope...ESC stands for Electronic Stability Control and it has nothing to do with an engine mis-fire. Although it MAY cut back on engine power as part of its magic.

I never said anything about engine misfire. I was simply suggesting that if you turn off ESC it won't malfunction.

YOU say....misfire and I think ENGINE. Just like one of those association tests.

I need to know why it is "malfunctioning". Maybe turning it off would prevent it from happening again, but why is it happening in the first place? And since this is supposed to be a valuable feature to the car - I should get full use of all the functions my car is capable of. This morning the ESC Off light came on while driving to work. However, this time there was no pulling of the steering wheel or pulsating of the gas pedal associated with the occurrence.

Yes, I agree..you do need to know the why of it. There is no question it is a very valuable safety feature and when needed VERY VERY valuable even if you don't know what just happened or how it saved your bacon.

It's not a very valuable safety feature if it's working incorrectly. I was suggesting turning it off only as a temporary measure, until Hyundai or the dealership techs can find the problem and fix it. It's not June21's job to trouble shoot the problem, especially if doing so might cause an accident.
