Thanks, JeromeP. Good advice, I will ask for a copy. I asked the dealer, when they said they couldn't find that anything had been wrong, if the codes didn't show that there was a problem. They said they got "temporary codes" that showed the error lights had come on but when they followed the codes in the diagnostic process they didn't find any problems. I don't know what "temporary" codes means, but I think they said they have now cleared the computer record. But they should have a printout, and I will ask as you suggest.

I agree it is distressing with so much high-powered diagnostics that they can't figure it out. I kind of resent the attitude that just because a problem goes away that it doesn't exist. As with a toothache that goes away when you get to the dentist--it will come back and it will usually be worse when it does.

Also they talked down to me, maybe because I am a woman and they think I'm dumb about cars, asking me if I knew about my auto-stop feature and could have confused an auto-stop with a breakdown. Honestly! 1) the econ button was NOT on, so auto-stop wasn't engaged; 2) the AC was on, so it wouldn't work anyway, and 3) I already told them it cut out while going down the road, not while at an intersection.

The same thing with my battery gauge, they wouldn't believe it usually runs at the top few bars. (Is mine unusual that way?) They asked if I was SURE. Then they asked if maybe I had been taking a new route and that would account for the difference. After driving around the same island for 2 1/2 years and 25000 miles, I think I know my car and have driven it on most every route on the island!

So that was annoying. Also they didn't want to give me a loaner because there is no problem that they can find, and they said the towing wasn't actually covered, for the same reason, but they would cover it out of the goodness of their heart. However, don't let me give the wrong impression with my venting, the service manager is genuinely concerned and the techs have been over the car repeatedly, but I can't help feeling they don't know how to work on this car and that fancy diagnostics don't make up for lack of experience with the model.
