## NHTSA's summary

Complaint Play/noise at height adjuster or in seat guide rail on front seats Cause Tolerances and variations in the manufacturing process Remedy 1. Inspect Seat Height Adjuster Barcode Label \(See Pic.1\) • Locate the barcode label on the cross tube of the seat height adjuster. • In isolated cases, the barcode label may be located on the front side of the cross tube.
