Hello, I had the 14S04 recall updated on 7-10-12. During the drive home, noticed that the electrical in the car was not correct and the radio would not set etc. Turned around and took car back to dealer and they did something and said the car was fixed. Next day, all power gone. Could not start car. Had to call roadside assistance who jump stated car and I drove to dealer who kept car on lot for 10 days while I was on vacation at my insistence. Since the update, my MPG has plummeted from 40 MPG to 34-35 MPG and the total Lifetime MPG over all has dropped from 38.0 to 37.7 mpg. The drop in mileage was immediate with the 14S04 update. The drive home on a 30 MPH drive was 17 MPG instead of the expected 50+ MPG for a low speed drive. Seems that low speed drives are well below 30 MPG which was not the case before the 14S04 update. I am wondering if anyone else is experiencing the reduction in MPG due to the 14S04 software update and if so, what was the resolution. I did respond negatively on the dealer survey for the service but the dealer did not respond.
