Service bulletin LI77.21-P-074971
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
Complaint Sliding sunroof panel of panoramic sliding sunroof reversed (temporarily, once, multiple times) during closing process without entrapment event. Cause Cause: It is not possible to save the relearning process for force progression after each actuation. A, e.g. mechanical sluggishness caused by aging cannot be compensated for here. Further analyses: Information from the control unit log of the panoramic roof control unit (TSSR223) is still required in a TIPS case. Remedy Remedy: Normalize panoramic roof with diagnostic system and carry out teach-in run for automatic reversing function. IF the above remedy does not solve the issue (namely): • The teach-in run for the automatic reversing function of the panoramic roof via XENTRY has still NOT been carried out
