Did you ride with the tech to duplicate the problem for them, or is it rare enough that this isn't possible? Or did you address that before about 3 threads back when you said the dealer had refused the ride-along? All of this seems quite familiar.My 2012 Santa Fe GLS 2.4L jerks and bucks while coasting. When you let go of the gas pedal the car would jerk. Is that normal for the car. The dealer could not duplicate the problem. Please help?
