We've had lots of problems with our sliding passenger door on our 2013 Nissan NV Passenger SV. At first we would lock our van, but the sliding door would still open and it would set off the alarm. (This is awesome when you have a newborn sleeping in an infant carrier.) Then, usually when it was cold outside, the passenger door would not unlock, requiring us to open the front passenger door and reach around to the inside lock to open the door. Now lately, we can't get the sliding door to open at all. We have a family of nine, so we have resorted to taking out one of the rear two-passenger seats (making the van an 10-passenger) so that we can use the rear doors for unloading and loading instead of having the seven children climb all over the front two seats with snow on the shoes. I, honestly, am sick and tired of climbing in the back to buckle our three youngest childen into their carseats, I just want the passenger door to work as it should. I've mentioned this problem three times now, and it spent two days at the dealership and wouldn't act up, so I was told they couldn't fix the problem. I'm desperate at this point. The door, even when it does lock/unlock, it squeaks horribly.
