Nissan Murano has dangerous design defects compounded by unresolved electronics problems. Design flaws: 1) ineffective defroster system, 2) long-armed wipers clog easily, 3) all doors must be unlocked to get gas (inviting carjackers). The defroster-wiper problem was made worse by electronics. While I was clearing windows the car locked in 13 degree weather. The car: 1) locks doors at random intervals, 2) puts the windows down without warning (the service manager says, "don't not leave valuables in this car!"), 3) the remote entry system often does not beep requiring that I check all doors (especially given the other problems with locks), 4) now the car sometimes tells me that the driver's door is open (when it is not). The car is virtually new (less than 6,000 miles). Nissan knows they have this problem. There is an internal service memo it. But when consumers complain they are "stone-walled" with, "we could not duplicate the problem." Last Friday my caracted up at the dealership. The service manager acknowledged in writing on Nissan letterhead. This problem exists and it is in a number of models -- maxima, Altima, titan trucks, and Muranos. Nissan shouldrecall all of the affected vehicles, provide rental cars while repairs are made, and to issue credit vouchers for all of the past aggravation they caused by their failing to provide good-faith solutions to the problems they know exist.

The windshield wipers cannot be raised to wipe off accumulating snow and ice without opening the hood. This is not simply an inconvenience, but, on highways during a snow storm, a significant safety hazard.
