I got my software update Friday morning (8/18/06) , and when I got home, ironically, my recall letter was waiting for me in my mailbox. Since Friday, I have driven about 200 miles, and have noticed maybe 2 MPG improvement in mileage. Not a whole lot. What I have noticed, is that my car now coasts more -- before the update, practically every time I let off the gas, the battery would charge. Now, it is often simply coasting when I let off the gas instead of charging the battery. I have not noticed any decrease in battery power. Other than that, I have not noticed any change in the functioning of the car. Has anyone else noticed any changes?
