    Just got my mail from Toyota regarding the software update and wondered if you guys have any issues with it like change in mileage. Service advisor told me that when the temperature gets too hot, it will slow down the vehicle until you get to a safe exit while on the highway. Is this true?

    There are a few threads in the other parts of the Gen III forum and the consensus appears to be no big change.

    I have a 2011 Prius Two. I got my recall done in the winter. Since the weather has gotten warmer I am getting 55 MPG in city driving. At this time in previous years I was getting about 50. My driving habits are the same and there have been no other changes to my car. Increased MPG as a result of the recall? Looks like it to me. I have noticed no other changes as a result of the recall.
