I'm guessing that the "novelty" of it switching between V4/V8 has worn off with me. I use to watch it when I had my '15 Silverado , but I haven't paid any attention to it in my '18 , just been letting it do its thing. As others have said, it's going to fail, eventually.
Told my wife the other night, that this is as close to "hybrid" that these trucks are going to get, since they don't make them in hybrid anymore. Told her that I'm at least going to test drive the crap out of the '23 EV Silverado, when it comes out.
