Honda has performed a software update on my 2006 Civic hybrid. The results are tantamount to having replaced my car with another that has markedly inferior response, performance, and gas mileage: * about 10 mpg decrease since the 8/4/2010 ima software update * rare iva assist on starting from 0, resulting in a noticeable lag between depressing the gas pedal and movement from a stopped position - this is a safety issue. * responsiveness of acceleration at highway speeds inconsistent and unpredictable - since this affects driver reaction and responsiveness this is a safety issue note: The software update renders the electric motor practically moot. Since in my case the battery drops its charge radically over a 24 hour period if not used, the update appears to be doing little more than preventing an already compromised battery from failing.

While driving at highway speeds, my cars instrument panel went blank, all gauges went out. This is an electronic panel. In addition, the cars engine lost all power. I had to coast to the side of the road. There was no indication that the car was running. It is a hybrid and it felt like it was in the auto stop mode when you are at a light, the engine was not running (at least you could not tell it was running). I turned the cars ignition off and then restarted the car. It started up again and the gauges were working and I was able to continue driving. I brought the car to the dealer and explained the symptoms. They checked the computer for error codes and found none. They were not able to find anything wrong. This is a safety hazard since the car is not drivable when this occurs. I expressed my concerned to the service manager and he stated that there were to many computers and wires for then to check them all and we would have to wait until it happened again. This occurred one other time while the car was in the drive way during the winter idling. When we got in the car after a few minutes, we noticed that all gauges were out. Again, turning the ignition off and restarting the car cleared the problem.
