I know the B58 is basically bulletproof and one of the most reliable engines BMW has ever made for the most part, but how reliable are the early ones? I’m heavily considering a 2017.

I had a 2018 and I know there’s now three iterations of this engine, but I wasn’t sure how the early ones stacked up to the newer ones. Usually any early/first product has issues early on that get ironed out over time. TIA!
