Summer of 2011, front driver's side door lock started getting "lazy" - would only intermittently lock or unlock (all the way) with the use of the key fob and/or the interior power door lock button and was much worse the hotter it got outside. I dealt with it for that summer and over the winter the problem went away.

Come May 2012 (warmer weather) the problem is back and even worse. Now add on to the previous problem, the front passenger side and the rear hatch. The rear hatch was the biggest problem because there is NO OTHER way to manually unlock the hatch!

After searching the web, I found many accounts with the same description. I took it into the dealer for repair and told them I needed the hatch and the driver's side fixed because someone online speculated that the circuitry going through the driver's door controlled all the others (somehow). The dealer replaced the actuator in the drivers side door first and the hatch still didn't work, so they replaced the actuator in the hatch. The hatch still didn't work. Someone THEN decided to pull out a schematic and they discovered that they needed to replace the actuator on the front passenger side to fix the hatch. If this problem is so common, why don't they know how to fix it right away???!!! The bill came to $975 (they put back in my old actuator in the hatch and charged me for the front two actuators).

TWO months later, wouldn't you believe now my back left door lock is starting to go!!! This is even more of an issue because it is my 5 year old daughter's door. I can be driving along and not realize her door is unlocked - allowing someone to enter at a red light. Additionally, what if for some reason I need to get her out of the car in a hurry and I've unlocked the doors, but her's doesn't unlock? I feel this is definitely a safety issue, however, just coming off of the $975 bill, I cannot go right back in there for another $400 bill!!!

Took my car to dealership paid $95 to have diagnostic test ran to tell me why my passenger door would not lock or unlock with the key or the switch, had to manually lock it. Was advised that the motor was gone out and the part alone was $400. Dealer suggested I continue to manually lock and unlock. Now the driver side has the same problem, to add to the frustration the hatch in back seems to work off the motor on the passenger side. Therefore to load groceries, or anything I have to unlock the driver side, reach over unlock passenger side then come out of car and lift hatch. Contacted Nissan and they advised me to contact dealer who said it is not under warranty so it would cost me to have it repaired. I am upset and disappointed as Nissan can repair this. My Altima is a 1997 and never a locking problem. Read somewhere another customer said the same thing was happening to her Murano. Car has never been in an accident or anything so why can't Nissan cover this?
