Service bulletin Bulletin 72K4

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

Cracks may, in isolated cases, occur in the cross member of the front seat backrests. This may result in the wiring harness becoming damaged on the sharp edge of the crack on the left seat. Diagnosis would detect the damaged wiring harness. A crack in the cross member for the front seat backrests does not constitute a structural problem.
