While driving in the city a warning came up on the dash stating "Supplemental restraint system problem. See your dealer." and the red seat belt/air bag symbol turned on and remained on for the remainder of the drive home (about 45 min at variable speed). As soon as I got home I turned the car off and back on and the warnings disappeared. I drove the vehicle for another 30 minutes and the warnings did not re-appear. However, I noticed that the seat belts used to tighten / lock while the vehicle was in D (drive) but they no longer do. I also tried performing a hard stop in a safe area to see if the belt would lock while my body was jolted forward but it did not. The vehicle had 6 passengers when the warning first came on and all of us experienced loose belts. This makes me concerned about the functionality of the restraint system, especially in the event of a crash.
