Megan, thank you for your post. On Saturday, Sep 29, I had purchased a used 2006 Kia Sedona after an inspection and a test drive but I neglected to test the 3-point third row middle seat safety belt. I mean, who tests the safety belts for a new or used car in the second or third row unless your are in the driver's seat or in the front passenger seat? Anyway, here is what I did to fix my stuck 3-point safety belt: a shot of WD-40 oil on the black screw to loosen the tight screw (with some paper towel underneath to protect the safety belt), a Phillips screwdriver to remove the screw, a flathead screwdriver to push up the metal latch. I found it much easier to push up the latch than to push down the plastic tab. I had to pull hard on the seat belt with my left hand and push with the screwdriver at the same time so two people could unstuck the seatbelt much easier than one person. After I pulled the latch free, I took a pair of kitchen shears and I trimmed the plastic tab so the latch could not be stuck again. I testedthe latch and and the latch could not get stuck because I had trimmed the plastic tab. I saved time and money by not going to a Kia dealership. Now, I am able to drive families with six people because I had unstuck the 3-point seat belt. I emailed the dealership to tell them that the previous owner (woman) of the minivan neglected to tell them of the stuck seatbelt.
