After receiving the computer update my fuel mileage has dropped 10 miles. The other problem in the rate of tire wear and pull. I took the car in for an alignment to a Toyota dealership because it was pulling they told me they did the alignment. After I got my car back it was still pulling I questioned them and they said that was normal. The last thing is I got new tires put on the car and had to replace them 10 months later because there was about 15 percent tread life left. The tires were rotated properly.

Was driving a 2011 Prius with just under 25,000 miles on October 18, 2012 on a 2 lane highway. A rear tire sidewall blew out. There was a rollover end for end down a very steep and long ditch. There were severe back injuries.

On October 18,2012 I was driving my 2011 Prius 2 on a 2 lane highway at 55 mph when the drivers side rear yokohama tire blew out on the sidewall. I swerved in to the left lane twice before leaving the road, snapping off a utility pole, going down a revine and rolling over end for end and side to side. I ended up in the middle of the back seat on my stomach facing the rear of the car. The drivers seat was broken back and my seatbelt was still on. I was in in the hospital for a month following back surgery. I had 3 cracked vertibre and one cracked rib as well as many bruises. Needless to say the car was totaled and I am still recovering 3.5 months later.
