I had my battery changed a few months ago at the Cadillac dealership and was never told anything about drive cycles to reset codes. Now it will not pass inspection and everybody tells me to drive eight more miles. I've driven it almost 300. I don't use the car that much because of the Flu Manchu. I asked so Cadillac of grapevine if they could do it and reset it for me and they said no. They just gave me a list of things to do. Every time I call they just tell me to drive the car. If it's so easy to do why can't they do it for me? I think it is absolutely ridiculous with computers so advanced in this day and age that all of this has to be done to get the damn car to pass inspection. I had never even heard or seen this problem before in my car or any of my relatives or friends. Cadillac needs to improve this feature or have their dealerships fix it when they screw it up. Now I'm going to be driving with an expired registration which I will probably get a ticket for. Do you guys want to pay the tickets? I didn't think so. Jay Bullock
