Had the tires rotated and oil change; all was good! Except thastAll was good...except that evening I was driving and saw my headlights were not working. Headed home thinking a fuse was blown! After some tinkering I checked the head light switch and and found it off :( It had been on 'auto' since the day I bought the car! I would have thought the 'mechanics' would have known to leave the switch on auto! No harm done...just 30 mins of troubleshooting! :)
