Had to pull my passenger seat and during re-install one of the bolts parted. The 10mm bolt was supposedly hardened (e.g. had ticks on top of head and had a nice coating of black Martinite).
I was using a torque wrench set to 40 ft/lbs and as I tightened the bolt it seemed to "stretch" for several turns. I expected that it would seat at any moment, instead, Snap.
For the sake of liability I decided to replace the broken bolt with OEM and dropped by the Dealer to order one.
I was informed that that bolt had been superseded by a new part number and that I would be receiving a "better" bolt.
Why the change?
Has anyone else experienced weak seat anchor bolts or am I just the lucky one?
But more importantly - Has anyone had a seat anchor bolt, or bolts fail in an accident?
I still have 7 other anchor bolts that are now suspect because they have been superseded by a "better" bolt.
Is there a recall for this? Should there be?
PS - I determined the torque value of 40 ft/lbs from this site Metric Steel Bolt Torques - Engineer's Handbook
