Condition
On some Model S base trim front seats, the forward inboard Huck BOM fastener and pivot bushing (nearest to the center
console) used on the front lift links may develop an interactive clearance condition, which might result in a rocking motion
in the seat. This does not affect performance, but might result in customer dissatisfaction.

Correction
Upon customer complaint of front seats that rock when occupied, remove and discard the original Huck BOM fastener,
and install a new pivot bolt and bushing.
