    Good to hear! Nah the car has been egr free for a long time now and it runs like normal on all trips. After getting that death rattle for a while go ahead and change your spark plugs. Knock/misifire for extended periods of time really eats the tips off of the spark plugs which can make you misfire easier or more. Every knock is a point towards a head gasket replacement so glad you got it figured out before it added up to one.

    No, you missunderstood...
    If the 12v battery is getting old, or is bad, the inverter will work harder and longer
    to charge the 12v battery. If they hybrid battery was bad, the engine will run more trying
    to charge the hybrid battery.

    I think it better gets 50+ with new traction battery. I have 2010 V at 267k with major maintenance including new plugs & coils, 12V battery, OCC installed, new pcv, cleaned intake&maf, new brake pads and rear rotors, flushed trans-axle fluid, both coolants. Right now getting 49.8 mpg with original battery
