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

Sliding sunroof panel of panoramic sliding sunroof reversed (temporarily, once, or multiple times) during closing process, without entrapment event. 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 24 hours (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.
