Service bulletin LI82.62-P-076756

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

Perceptible volume jumps at 15 and 10 mph. When reducing the speed of the vehicle, the volume is reduced in clearly perceptible jumps. This is particularly perceptible at a moderate basic volume (i.e. lower than typical levels of household noise). Software in sound control unit SND7 (N40/3) Currently no remedy available. Replacing the hardware will not remedy the problem! Remedy will be available with next software version for sound control unit (Q4/2023)
