Turning off ESC does not affect it. Has anyone else experienced this. My garage guys say with no error codes cannot fix it.

ESC = electronic stability control. When functioning normally, the ESC light will illuminate and cut power when the vehicle detects tire slip. When the car has regained stability, the ESC light will go out and normal throttle response will be given back to the driver. This is most noticeable in wet/snow when turning under throttle where ESC prevents the car from spinning out of control. I've also seen this in my car when driving over railroad tracks while accelerating.

So if you are getting ESC activity when you shouldn't be, then I would look for faults with the wheel speed sensors and associated wiring. If your garage guys can't figure it out, then take it to an automotive electrician.
