The wiring harness, in the back door has broken, because of a Nissan engineering problem, both the harness and wires have broken, which according to NHTSA the front passenger side airbag will not deploy, resulting in my having an unsafe truck according to NHTSA, I contacted Nissan and was told that the campaign had ended, so they refuse to repair my truck according to the guidelines set by NHTSA. At what point does Nissan decide that they can decide which trucks to repair, I have to wonder how many other unsafe Nissan trucks are on the highways.

The issue I am having is with my 2004 Nissan Titan. When it gets cold out, all of the door handle freeze and won't open. If you are lucky after a few hours and you do get it open, you can't get them shut. Several times I had to tie the seat belt around the interior door handle in addition to holding the door close so I could get home. I took my car to ricart Nissan and they said it will $1000 to fix all 4 doors. So, I contacted Nissan directly and they refused to fix it. This is a serious safety issue and someone is going to get injured and/or killed.

Drivers side door mechanism freezes. Door can be opened from the inside but will not latch and close properly. This cause the driver to hold the door closed or to lock themselves in the car, to try and defeat the latch mechanism. Nissan dealer has been contacted, but they claim no manufacturer responsibility, although they do have a $500 fix, for this non-safety related issue.

Numerous problems have arisen with my leased 2004 Nissan Titan king cab. Including serious vibration problems that occurred upon braking to the point the vehicle was parked until the dealer finally agreed to at least 'turn' the rotors. Eventually brakes were replaced by dealer 6 months after the initial problem. Currently facing problems including a noise at startup that everyone can hear except the dealer mechanics, an overflow problem with gas tank even though just a few liters have been put in an empty tank. Additionally major problems with driver side door refusing to open from both the inside and outside. Dealer has realigned door numerous times but problem continues. Dealer states the door problem is due to a poor design with a heavy door on inadequate hinges. Occasionally have had to drive while holding door closed. Extremely dangerous considering weight of door. This truck is barely one year old and problems just keep piling up with little dealer support offered.
