I just came across an article that said that there is a recall for several Lexus models, including the 2019 ES300h. The recall involves replacing a faulty brake pump booster. I'd guess that the recall will apply to some here who have the ES300h.

It strikes me as curious that, if a potential safety problem is discovered, Lexus would be waiting until September before sending out recall notifications

 

Thanks for sharing this article. I agree that it seems strange to wait, but the article suggests we will be notified “by September”. It may simply be that Lexus needs to get replacement booster pumps out to their dealer network - along with a documented procedure?
