I'm not sure but do they do that when they die- I thought they had a very long life these LEDS ?
i do know that on my Civic the third brake light would not work here and there- and it turned out that Honda's vendor had used inferior solder that would crack and the boards would separate from the wiring and the connection was bad- a quick hit with more solder and hot tip fixed it good.
(I bet the HR-Vs that have ;bad dashboards; have a similar problem -but that is just my guess.)
