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

SUNROOF REOPENS WHEN CLOSING FROM TILT POSITION This Service Information bulletin supersedes SI B51 22 16 dated August 2016.. Sunroof reopens when initiating automatic close from tilt position \(momentary push\) even though track is free of obstruction. Sunroof can be closed by initiating closing without anti\-trap protection \(push and hold after anti\-trap reversal\). Anti\-trap threshold value too sensitive in FZD \(Roof Functions Center\) software. Malfunction in the slide\-tilt motor may be caused by the vehicle standing in high ambient temperatures for an extended period of time.
