I know nothing about cars, but for the last month our RDX 2017 3.5 L with 60k miles makes these weird sounds like it's trying to start and the lights flash on and off. We will be sitting there in the living room and hear the car making these noises intermittently. It reminds me of a post you made a long time ago where you were saying that the battery was sending out electricity to the computer, but you couldn't figure out what it was. Anyway, I took a video of when this occurs and edit it so I can show you three episodes of it. Sometimes this seizure seems to last longer (five seconds) however, it usually only lasts a brief moment. I took three different episodes and clipped https://sendvid.com/h2ie4e32 them together. These episodes occurred over about three minutes. And then stopped after about 10.

Any ideas would be great
