OK this was a weird one. I have had my kids in the back on several drives so far with no issue. However today was my first day back to work and had to show off the new car to the guys at work when we went to lunch. One guy was in the back and the rear seat belt alert would not stop going off. He even switched seats. We had to buckle all 3 belts in the back to get it to stop finally. Anyone had trouble like this?
