I got a message regarding my service interval for 6000 miles and I had taken my car in for an oil change at 3500 miles. The service department said they probably forgot to reset it, so they had 3 technicians and the service manager try to reset it. After an hour they couldn't reset it and told me I needed to bring it back for them to look at it. I now have time to take it back in, but other people said I should be able to do it, but haven't been successful. Can someone help me?
