Mid/rear Seats Assembly problems of the 2007 Nissan Murano

While driving my wife heard pop and driver's seat broke dipping to the left at rear of seat. I've investigated this matter and seat will cost over $1,000 to replace and is a common problem. Can't understand why if this is a common problem this is not subject to a recall. From the number of complaints it looks to me as though the metal used to make the seat bracket is not sturdy, or defective metal is being used.

While driving the driver seat rear seat lifter bracket, part 87473-ca00a broke. The part has been redesigned and is now part 87473ca01a. While the part was broke the seat had a lot of movement and tilted toward the driver door. It cost $579. 48 to repair.

Broken drivers seat (power leather seat). Left rear seat support/frame appears to be broken. Driver's seat has no no support from left rear part of frame - tilted back toward the left rear corner and rocks on the left side. Also appears to be unrestrained (can rock forward)on left rear corner.

Driver's left rear seat attachment point gave way during a shift in body weight. This created a floating type condition as the left rear of the seat shifted up and down in correlation with the vehicles movements/cg shift. Took vehicle to dealer to point out unsafe condition and was told that it was not covered under warranty despite the vehicle being only 3 years old with less than 100,000 miles on it.

The contact owns a 2007 Nissan Murano. While driving approximately 25 mph, the driver's seat failed and extended to the rear seat. The contact immediately drove to the dealer and was informed that the seat could be repaired. The dealer welded the seat to the track as a temporary remedy. On July 6, 2009, the seat failed again. The dealer recently stated that they would no longer weld the seat because the track needed to be replaced. The contact paid $400 for the welding and $1,400 for the track replacement. She stated that she would not repair the seat since the failure recurred. The manufacturer stated that they would make an agreement with her to split the repair cost. They later stated that they would get in touch with her and that no recalls were available; however, the dealer and service manager confirmed that the failures occurred. If a crash had occurred, the injuries could have been fatal. The contact refused to pay for the repair and stated that if the seat leaned toward the air bag switch, the air bag would deploy. The state attorney general is mailing her a packet to report the failure. The contact informed the dealer that she will go the media about the issue. The manufacturer stated that this would be irrelevant since no crash occurred. The contact found several NHTSA complaints and an open investigation regarding this issue. The failure mileage was approximately 39,000 and current mileage was 42,000.
