Service bulletin LI82.70-P-079903
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.

Remedy A corrective measure involving modified wiring harnesses and revised microphone connections is in development. The updated solution is scheduled for release in December 2025. Once the measure is implemented, this bulletin will be updated and versioned accordingly.
