Service bulletin Q648NAS1

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

Situation: An issue has been identified on a limited number of vehicles within the listed Affected Vehicle Range which may have been manufactured away from process and as a result, when the fabric roof is in the open position, there may be contact between the folds leading to a wear pattern or fraying being witnessed on the roof at the rear quarter and drip rail seam. The level of wear is dependent on the time that the roof has been in the open position. As this is a cosmetic concern that may cause customer dissatisfaction, the recommended rework must be undertaken at the earliest opportunity.
