I have had multiple issues with this vehicle. I have replaced the engine to the tune of $7k. I have replaced spark plugs like theyre going out of style. My latest issue, on a trip home i got service hybrid system on the display, the car shut down, i let it reset, restarted it and it was fine....now it wont start, i have all my lights. can listen to radio, use dvd, heated seats, sun roof...all of it except when i go to start it, nada. I replaced 12v battery without change. The only code it throws is P0AC4.....any ideas? Just want to trade it at this point. Its worth a whopping 4k new engine and all and im done sinking big money into this to be able to drive it for 6 mos and sink more big money into it.

    That is a PCM code that sets when a failure is detected by the Hybrid Powertrain Control Module. You need to go to the hybrid controller and access the codes set there to continue.

    More precise you need a technician who has studied more and invested in tooling beyond than the average technician in order to be ready to competently address hybrid vehicle, hgh voltage system issues.
