ESC system seems to govern the car and NOT allow speed over 70 MPH.

What is your question?

I just bought this Hyundai Genesis Coupe 2.0T. But I have noticed that when the ESC (Electronic Stability Control) is on (normal), as soon as I reach 70 MPH, the engine just acts like it is governed. If I slow down to 60 and accelerate right back up to 70 and nothing past that. Like an old carburetor loading up. But if I manually turn off the ESC, it is fine. and will get up to 90 in no time. From what I am reading in the owners manual, "the ESC is designed to stabilize the vehicle during cornering maneuvers". Is the typical? should the ESC govern my speed while driving on an interstate and NO cornering at all? I would love to hear from someone that has had there 2.0T longer than me. Thanks! Jeff
