Yes, that's what I'm thinking. I've searched here and on the net, so far I haven't found any clues what those conditions are. I'm betting a series of cold starts and ??? Because besides my drive halfway across the country, she's been using it as a daily driver for three weeks. And resetting the computer would not be the right thing to do. Thanks! I'm on track I think.

Actually my daughter is the new owner of a 2013 hybrid. She inherited the car. It runs and drives great (I shuttled it almost 2k miles from Texas to California) and she took it in for smog test and it failed. The technician told her to the computer could not be read, and she needed to have the computer reset and drive it more. From past experience with another car this sounds backwards as resetting the computer would start the 'clock' over again. And its certainly been driven enough (see "shuttled from TX to CA", above). There have been no 12v battery problems with this car and my Dad took it in for regular maintenance. On the of chance of finding relevant information I've searched for resetting the computer and come up empty.
