    Hello, I have 2010 Toyota prius that I'm stuck and not sure what the problem is. I get the triangle of death and check engine light. Took to Toyota for diagnostic and notes state "generator not charging and motor not operating at times, with no motor codes to support suggest PMC ecu, if not resolved need inverter". I've replaced the PMC, hybrid water pump, and inverter. Did not fix the issue, car will go about a mile then dashboard lights up, and car loses power, like hybrid system shuts down. The only thing I can think is that the hybrid engine needs replaced. The battery seems to be charging and I had reconditioned a few years back. Checked fuses and they all look fine. I was rear-ended, but it hardly caused, damage, but noticed issues some 50 miles later. Any ideas?

    You need to find out what the trouble codes are. Did the Toyota dealership list the trouble codes on the paperwork for the work they did?
