Service bulletin L-SB-0020-20

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

TSB: Some 2019 model year ES 350 and ES 300h vehicles equipped with the base audio system may exhibit a front-rear sound imbalance where the rear sound bias is less than expected even when fading the sound to the rear. The amplifier logic has been updated to address this condition.
