fuel smell Cannot make a service appt until June 2026 - at the earliest

Seatbelt disengage on its own. I noticed my seatbelt disengaged the other day while I was in a drive thru. I was not driving at the moment I was waiting in the line. I know the seatbelt had been latched prior to it unlatching. I mentioned it to my husband and he said the same thing recently happened to him. Upon research I noticed this may be common with Hyundai.
