Left work yesterday, drove 5-6 miles to grocery store, ran in for fruit and veggies, emerged to find car won't start. No slow turnover, just an odd noise when the key was turned. Opened the hood, stared futilely at the things I don't know how to deal with, wiggled a few wires, then tried again. Car starts. I drive home.
Called the dealer and begged for a service appointment for today, despite their busy schedule. Drove to exercise and back with no problems afterwards, but worried about being stranded.
Drove to dealer this morning to drop off the car, and had to park it a couple of car lengths outside their service entrance because of the crowd of other cars. When I finally was clear to pull it up into the building, it wouldn't start! How about that--take the car to the shop for a problem, and the car actually exhibits the symptoms!! It'll never happen to me again.
To make a long story short, I've now got a new battery. (Probably due--the old one had lasted 7 years.) And have had the overdue routine service done, and let them balance the tires (which they thought was needed) for a bonus. And I'm not worrying about the car starting every time I turn it off.
