uuggghhh I woke up, got ready, started my car and it went click click click click and the service light came on. Call into work to say I'll be late Im not going 25 miles away with my service light on... take it to the garage and LUCKILY I was just really OVERDO for an oil change and my tire pressure in all 4 tires was very low! $65 later (new headlight and air filter too) and I was good to go.
