We have a 2007 Hyundai Santa Fe GLS 2.7 with Automatic Transmission. Our problem is when I am driving the car and my wife is in the front passenger seat. Regardless of whether my wife buckles up before or after turning on the ignition, she frequently gets a seat belt OFF warning light. She is properly positioned upright in the seat with both feet on the floor. She weighs 115 pounds and is 5'4". This really freaks us out because safety was a major buying consideration. It will often, not always though, go off when I will pull over, turn off the engine, and restart. We took it to the dealer and they said there are no Technical Service Bulletins on this problem. Anybody else with this problem? I really thank you all in advance for any feedback!
