NHTSA Complaint #11554727 — 2012 TOYOTA SIENNA

The third row passenger side split was stored and then put back up. Upon lifting the seats, pieces fell out (spring, washer, and screw) and the locking mechanism would not lock the seats into place. I am not sure how long these parts were loose, but it is a major safety hazard as the vehicle seat was not secured to the car as intended. We plan to to follow up with Toyota, but upon investigating, it seems that this is an issue for several 2011 Siennas. My Sienna was manufactured 4/2012. This is the smaller of the split seats, but out of an abundance of caution, we don't plan to use the 3rd row at all until a remedy is produced. Unfortunately, I saw only consumer complaints in regards to the 2011 3rd row seating issue and didn't see any solutions.
