We have had our new XC90 for one week. So far we love it. However, last night I tried sliding the second row passenger seat to the rear. It would only move half way back. It feels like is being blocked or caught on something. I looked and could not see any obstructions. I vaguely recall someone else on this thread having a similar issue with some type of clip on the seat causing a problem. I could not find the post. I would hate to have go to the dealer to resolve. Especially, if it is do to user error. Any help would be appreciated.
