Service bulletin LI77.21-P-075806

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 Sensitive parameterization of the automatic reversing function of the panoramic roof in combination with the seal counterpressure. Remedy 1. Open the sliding sunroof panel of the panoramic roof completely (sliding position) and wait 10min (so that the seals can expand/be fully established, if they have been flattened). 2. Standardize panoramic roof with diagnostic system and carry out teach-in run for automatic reversing function. Reference to escalation closing during reversing processes (also described in Operator’s Manual), if vehicle in customer possession (see Video_1): If the panoramic roof blocks up when closing and then opens again slightly (reversing process): Immediately after automatic reversing, wipe forwards on the control panel of the overhead control panel and hold until the panoramic roof is closed. The panoramic roof is closed with greater closing force. If the panoramic roof blocks up again and then opens again slightly (reversing process): repeat previous step. The panoramic roof is closed again with greater closing force.
