One thing that years and years of looking at CR has attuned me to is that car electronics break all the time and are the reason why many brands have poor reliability scores even though the engines run, the lights turn on, and the doors open and close (most of the time).

German and American cars seem to have a very frustrating time with reliable electronics compared to Asian brands for some reason, and the problems persist year after year.

For especially electronic heavy brands, typically higher-end ones the problem can become particularly pronounced, the bottom ranked vehicles on this list are mostly high-end, expensive, and packed full of gear (except for a few). Electric vehicles and PHEVs have the biggest problems being almost entirely electronics.
