Just a reminder:
Should you decide to have the acceleration and weird shifting remedied by having the chip's program updated, have the driver of the vehicle drive the car for at least 20-30 minutes off the dealership's service lot. The reprogrammed chip will learn from the driver's driving habits up to a week. If your wife uses the car more often than you, she should do the driving.
I think this is where Toyota made its mistake by opting to use a "learning" chip in their vehicles. Toyota thinks that the car should learn from the driver and allowing the car take over the responsibilities on when to shift, when to accelerate, etc ... as opposed to the driver learning about the car. I personally would rather learn about the car's quirks and modify my driving habits accordingly.
I've been told that several models have had their transmissions replaced because of damage related to the erroneously programmed chips. Well' ... this problem would not have occurred if the chip was programmed to a set of values ... period. Let the driver learn how to manage the car themselves. Taking away the human factor -- decision making -- is not making me comfortable with the technology. What happens if the family has only one vehicle and multiple drivers -- mom, dad, son, daughter, etc. What then? The car would get confused trying to learn from all the drivers. Isn't this idiotic?
