2015 Jeep Grand Cherokee drivers side heated seat burned a nickel size hole through the seat, burned a hole through my girlfriends sweatshirt and burned her skin. Thank god she was able to maintain her composure and pull over to a parking lot and get out. What if she had jerked the wheel (as it startled her) and caused a crash? What if she was on the highway?? What if the vehicle started on fire?? The vehicle is currently at the dealership and being inspected. There were no warning lamps or other symptoms.
