Service bulletin LI91.10-P-076798

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Noise at front seats between seat-back lining and function carrier. Noise is caused by friction of the two component parts. Remove the seat-back lining (back panel) of the front seat concerned using a special tool. Via adhesive bonding, affix 2 pieces of felt at the lower seat backrest structure (see pic. 1). Via adhesive bonding, affix 2 pieces of felt in the upper area of the seat backrest at the function carrier (see pic. 2). Pic. 3 shows the function carrier from behind: Begin applying the adhesive bonding of the felt at the edge (see red arrow). Ensure that the adhesive bonding is applied in the center. Then fold the felt forward. Pic. 4 shows the function carrier from the front: Continue to apply the adhesive bonding to the forward fold. Ensure that the adhesive bonding is applied in the center.
