“Owner (Hyundai Tucson 2008 gls) Hyundai customer service and representative is the worse. My vehicle has been cutting off without any warning. I've taken my car to the dealer numerous time indicating the car cut-offs without warning. In addition, I took my car to the dealer in 2009 complaining about the cut-off and not picking up speed.

Needless to say; they have done nothing. …”
