Service Indicator Comes On Early?

I am definitely glad they are monitoring everything. As for being kept in the dark about it, I prefer to know what is going on. What is frustrating is the sense of impotence that solid state electronic devices give. If this thing had old magnetic relays, with contactors, the failure rate would be higher, but you could look at it, see the stuck contactor, or see the soot around the offending one, and sand it with a match book striker, and get home. An SSR, like everything solid state, is a magic rock. If you pulled the cover off the HPDM, you might see soot, if the SSR had cooked completely, but everything is potted in epoxy, and nothing you could jerry rig anyway.
The solid state electronics are actually an order of magnitude easier to see and tell what is going on vs. an older mechanical system though. While you're not going to "pop the cap" and inspect a silicon junction, the failures at the junction level are so rare as to be virtually immaterial. The interaction between components and monitoring and management ability is where all the magic happens, and that is where solid state electronics have their gigantic troubleshooting advantage. The artificial barriers that make modern cars "difficult" to troubleshoot are almost all a product of OEM rent seeking and obfuscation by unnecessary proprietary methods. Sad state of affairs for the average owner currently.
