I posted earlier that my car did this and I got it fixed. I can't even remember when that was - like a week and a half ago I think - and my key has done the same thing a couple times since the "fix." It's only done it maybe 2-3 times, but then again I haven't been driving much lately either (college - no need!). So I really have no idea how repeatable it's gonna be. Should I take it back in? Or is it possible that I'M just doing something wrong? (Doubtful - never did it at all in the first 18 months I owned the car - just now!)
