Passenger seat belt won't extend half of the time. We have tried with engine on or off, put it in park and in gear, door open or closed and every other trick. We have pulled the belt straight up and down and every other angle. We have adjusted the height for tall or short riders. We took to the auto dealership, and they said it would not work for them at first then it started to work. We have had riders in the passenger front seat ride with no seat belt on because they couldn't extend it and gave up. It should work every time there because it is a safety issue that should be fixed.
