I have had my Aveo for almost 4 years, and have had no problems besides the locking mechanism on the gas tank door breaking off in the first year.
And now out of the blue, my key gets stuck in the ACC position and won't turn off. I found that if I disconnect the battery, my key will turn to the off position and I can remove them, but this is inconvenient. I found this out because I work the graveyard shift and didn't want my battery to die, so I disconnected the battery and then showed my co-worker what I was talking about, and as soon as I showed him, the keys came out.
And now starting today, it takes a couple of tries to get it out of park. This better be the end of my problems.
It's probably the beginning of your problems. I mean, even Aveos get older.
You might need a new ignition lock/switch assembly.
