hello, I have a 93 Subaru Legacy L Sedan. Occasionally, perhaps three times a week or so, the ignition will not fully lock, therefore not permitting the key to release. This is particularly frustrating when I'm trying to get to work on time! Usually what I have done is restart the car, drive it a short distance, and then try to turn it off completely again. Sometimes I have to do this a few times. It's so annoying. Does someone know why this would happen?
