The driver's door will lock intermittently on its own. No other doors so this. It causes a lot of inconvenience and has been a safety issue on several occasions. Several times the car was not locked when I thought it was because I tested the self-locked driver's door. My niece has the exact same vehicle with the same problem. Both her dealer and mine have each denied there is any problem or service bulletin with this issue. I also note that another party has reported the same problem.

Immediately after purchasing 2 separate 2004 Muranos around the middle of July 2004, we had the driver-side doors on both vehicles intermittently lock about 20% of the time. The engine can be running or not, the key can be in the ignition with the engine off, or the key can be out of the ignition entirely. Three separate family members have had this happen several times each on both cars. Fortunately, there have been no dire consequences yet. I have walked home from the mail box to get the second key. My wife and her father have been at a gas station and could enter the car through one of the back doors. Potential safety issues: Being completely locked out of the vehicle on a road in the desert with no water and unable to get into the car; my wife being out alone at night and unable to get into the car for her cell phone to call for help; a child or animal being locked in the car in the high heat in the Arizona desert (an opportunity for a real tragedy). We have contacted the dealership several times and taken the cars into the service department. Our service manager said he believed it was a design flaw. Apparently there had been a similar problem with the 2003 Muranos, but Nissan says this has been fixed on the 2004 models. It hasn't been fixed on ours. Nissan's customer service claims there have been no other complaints and that we (the consumer) were the problem. It is hard to believe that three separate persons on two different cars on multiple occasions have the same issue if there is not a problem with the vehicle. And this is with all of us being mindful of the problem and being careful how we close the door. As a last resort, I have written a letter to Mr. Carlos ghosn, CEO of Nissan, N.a. apprising him of our difficulty and of our inability to get any help whatsoever from Nissan. In short, nothing has been done. No repair has been made. Nissan has essentially informed us that they don't have a problem, we do. Can you help?
