Front Seat Head Restraint problems of the 2010 Subaru Forester

Front driver seat -- while driving heard a metal pop sound from the seat. After investigation the right side of the driver seat has separated from the seat tracks. Seat has not been abused as drivers weight using this vehicle is < 225lbs. Have seen several posts on Subaru sites indicating left side of seat failure. This is right side of seat. The seat no sits lower on the right side causing awkward seating position, leaning toward center of vehicle for the driver. Should vehicle be involved in crash I suspect the driver will not be properly positioned for proper restraint with seat belt and not center with the airbag potential deployment. All resulting in unnecessary driver injury. The vehicle has less than 90,000 miles.

While sitting on the driver's seat, the front left portion of the seat collapsed downward, and now has no support from the frame of the seat. Dealer has confirmed that the welds on the seat bracket have failed. This seems likely to be the result of a factory defect, as this seat has not been abused or had an abnormal amount of weight supported on it. My concern now is in the safety of the restraint system.

Drivers side seat cushion collapsed on left side and became loose due to a weld failure on the seat frame. I believe that the loose seat cushion compromises the integrity of the restraint system and warrants a safety recall.

Noticed driver's seat (power) was not providing normal support on left side. Assumed it was just age related deterioration at first, but when I investigated I found two welds on the seat frame assembly (pn 64100sc001) had failed. I was concerned that this might have an impact on the performance of the restraint systems and contacted dealer and Subaru to seek assistance in a repair. None was offered. I ordered a replacement factory part from my dealer and notice that the replacement part had been modified by adding a screw to the welds holding the bracket on. Checking on the internet, it appears that this is not an uncommon problem. I was able to replace the seat frame, but this requires removal and disassembly of the seat which is a fairly advanced diy job.
