| Seats problems |
After I stopped I felt the seat go back. I found the bracket that attached the seat frame to the sliding track had cracked. The metal appears to be too brittle and thin for the application. I am a reliability engineer with significant structural failure background and it appears the thin metal (~1/16") shattered from imbrittlement or some similar process.
Sunvisor was repaired by dealer a number of times, but continues to come out of ceiling. Turn indicator - the handle will not return to the off position. Left side of driver seat - all support on the lower portion on the left side of the drivers seat has failed. You must sit on the frame of the seat. The driver weighs only 145 lbs.
Metal part that connects seat to the frame track broke, causing seat to fall of track. Please give any further details.
