2012 Nissan NV Passenger. Lots of trouble with the door! Door switches had problem making contact since day one (as evidenced by door locks not working, alarm going off, etc), and occasionally while sliding the door open it would make a really loud popping sound. (I later found that his was an improperly tightened bolt on the upper roller, and every time the bolt slipped a bit it would make the noise.) When I brought it to the dealer the first time, they succeeded in stripping out the Torx heads on the bolts, getting my carpet greasy, and replacing the scary popping noises (from the upper dovetail) with clunky rattling noises from a loose door. I bought the factory service manual, and found that every spec is out of adjustment (measurements of the gaps between the door and the body). However, the factory service manual does not offer a correction or adjustment for these items, only a procedure for adjusting the dovetail, switch, and lock assembly. In a nutshell, that procedure is to loosely-loosen everything, then open and close the door a few times, then retighten everything (making sure that it didn't move after closing the door). This made the noises go away, but the electrical contacts never fit. To make the door fit better, you need some tension on the upper dovetail, which causes annoying noises. The second trip, dealer left it in this state: the electrical works now (they also replaced the switch assembly), but I still hear popping from the upper dovetail, particularly when first starting to move. I don't dare to adjust it myself yet, because I can ignore the noises from the upper dovetail (since I understand their nature), but want my doors to lock, and don't want to work on it myself if I'm going to push Nissan to fix it. I'm currently on vacation with the family and have 10k miles on it. So far the noises have been noticed independently by my wife and her mother (yesterday and today). My comment? "I don't hear it, but I'm glad to hear you do, it's a van, live with it" I might take it back, that's actually why I was searching this forum. Oh yeah, the A/C went out completely at 5k miles. That brought me back to the dealer! Also had a bit of trouble with the CD/USB playing back randomly, but that got fixed. Also had a problem with the map lights, which required replacement of the entire roof liner! Love the van though! p.s. don't bring this van to downtown San Francisco, you'll leave paint behind, and valets will cringe!
