Attention Prius Owners, I believe I have discovered a previously unknown Mechanism of Low MPG.

well it seems the system relearned my driving habits after around 2.5k miles...so happy my car is back to normal but afraid of next time.

 

I the great scheme of things, you are talking about a drop in the ocean.

 

I had my HV battery replaced a few weeks ago, and my mileage has seen a significant decrease. Reading this long thread to figure out what I can do about it.
