The seat belt retractors in the rear are defective. They do not allow for movement, and get tighter and tighter until you have to unbuckle (defeating the purpose of a seat belt) and readjust. See the other identical complaints on this site for details. My problem is just as they describe. In dealing with the Nissan dealer, they first said they could not duplicate the problem. I took the service writer to the vehicle, and demonstrated the problem for him. He then replied "oh that problem (I had made the problem perfectly clear when I took it in), well, they all do that. We had another customer complain, and we checked an 06 model, and they work the same way". all that means is that 04 and 06 are defective, and probably the 05 as well. I have had the truck in to service this issue three times, always with the same result: Denial that the problem exists, and then acknowledgement that "they all do that" (and implying that they can't fix it since "they all do that"). yesterday a service writer admitted Nissan was aware, working on a fix, but didn't have one yet. 800-nissan1 denies that any defect investigation (or solution) is under way on this problem. Someone is not being honest. The following seems clear from my experience and the other complaints on this site: 1) the defect exists, 2) Nissan has failed to acknowledge it's existence, and 3) Nissan has not addressed the issue (they are still producing vehicles with the same defect. I invite the NHTSA investigator to contact me, view my vehicle to confirm the existance of this serious problem. For that matter, view any Nissan Titan crew cab (in Nissan's own words: "they all do that", even the 06's). Two questions remain: 1) why, according to 800-nissan1 (Nissan warranty center), is there no investigation under way of this important safety defect, and 2) more importantly, why the NHTSA site does not list this important safety defect under the list of investigations presently underway?

Seat belts locking up. Seat belts on front passenger and rear outside passengers have a retract system that does not allow passenger to lean forward. Belts are locking up requiring passengers to disconnect belts from belt latch and letting belt retract all the way back to stored position. Then they can be pulled out and reattached and they work for awhile. They will do this at anytime. There is no set time that it happens. It happens with different passengers but mostly with women. The drivers seat belt does not have any lockups. The seat belts have been replaced 4 (four) times to date and are going to be replaced again as soon as they are received by dealer. They have been covered by warranty. We have lost count of how many time this has happened. Probably 500+. the safety issue is that belts are disconnected while driving and then reconnected leaving the passengers unprotected during this procedure. Belts just get tighter and tighter until they have to be released and reset.

: the contact stated the shoulder straps on the rear seat belts lock up while in use. This is a constant problem and the passengers cannot move as a result. The dealership replaced the seatbelts, but the problem persists. Other vehicles on the dealership lot were inspected and they all have the same problem. The manufacturer states this is how the vehicle was manufactured. Updated 03/28/06.

The contact stated the rear seat belts are not working correctly. When the seat belts are in lock mode and then released, the seat belts lock and will not pull out for use. Dealership installed new seat belts, but the problem still existed. He contacted the manufacturer, and they had no information on the problem. The problem existed when the vehicle was purchased.

While driving 15 mph consumer's vehicle crashed into a tree. Upon impact, rear middle seat belt unlatched on its own. Vehicle was taken to the dealer for inspection, and mechanic determined that the seat belt needed to be replaced.

1) a child safety seat was installed in the center rear seating position, and secured with the vehicle seat belt. The belt was fully extended to engage the retractor lock. Upon removal of the child safety seat, the seat belt was allowed to retract. 2) the failure occurred when an attempt was made to extend the seat belt for it's next use. The seat belt was locked in the child seat safety mode and could not be extended, and therefore the rear center seating position could not be used. 3) Nissan dealer replaced the seat belt retractor, and the new part is exhibiting the same problem. The dealer explained that this appears to be occurring in all Titan's and the seat belt can be released by forcing (20-30 pounds of force) additional belt into the retractor to release it. The problem has not been corrected and the replaced part is not available.
