OMG, I’m not crazy after all! When I heard Jennifer’s car problem, I knew exactly what she was talking about. My car does a very similar thing, and the dealer thought I was nuts.
Different car, slightly different scenario; same problem:
I have a 2002 Volvo S60 (90k miles). I never had a problem until 2006 when I got married and moved to my husband’s house. There was no room in the garage so I had to park my car in the driveway, which slants downward. If my gas tank gets below ½ full, the car won’t start in the morning. Imagine my surprise the first time that happened! If I add gas, it will start. My husband suggested rolling the car to a flatter location (inside the almost full garage), and that works too.
