What owners wrote

Driver heated seat shorted out and caused burn to leg. System has not been repaired, will wait to hear from Kia Customer Affairs prior to decision to repair. I was injured by this and have concerns about the safety of the vehicle, will this happen again if a new grid is installed. Kia dealership confirmed that the grid showed high resistivity but also claimed since nothing is melted I couldn't have been burned. The vehicle has only been inspected by the dealership currently.
