We finally had the harness update done. We're probably one of the last to do it. My wife called and said the check engine light illuminated, but the car seemed to be running fine. I met her at the dealer, and sure enough, I hopped in and it was fine. No light, no problems. Since the service dept had just closed, they couldn't scan it, but I was pretty sure what was causing the problem. She took it home, and later that night I took it out. It seemed to behave as normal (this was Thurs). Since we made an appt for next Tuesday, I wanted to make sure it was OK to drive over the weekend. Finally, when returning home that night, the light came back on and hybrid activity stopped. A restart didn't help.

On Friday morning, the light was off again. I followed my wife to work, and there were no problems. I called my retailer, and asked if I should drop it off now or keep it for the weekend. They said to drop it off whenever--they may get to look at it earlier. I brought it in around 1 PM, and they set me up with a rental (Toyota Corolla). By 4:30 the same day, they were done. We picked it up that evening, all better and nicely washed. So far, it operates just the same, or maybe just slightly smoother at lower RPMs. My wife said it doesn't "creep" as much in D now, but that was all she noticed. Charging/assisting seems the same.

In short, I'm happy with my retailer. Hopefully our mileage will continue to be good, but I have no doubts that it will.
