I have a 2010 Chevy Aveo and the key will not turn to the off position. It starts and drives but when you try to turn it off it will not turn past the accessory position to the off position. When the car has been sitting overnight the battery goes dead and it needs to be jump started.

    Is this an automatic? If so, the problem probably lies with the mechanism in the shifter which does not allow you to turn the key off all the way without it being in park. – Pᴀᴜʟsᴛᴇʀ2 Aug 3 '15 at 15:55
  • In addition to what Paulster2 said, it could be that you aren't removing the key right. I hate to ask, but the car is in Park and do you push the key in when twisting it? Sorry if it sounds silly, I just want to make sure we are covering all the bases. – Poisson Fish Aug 3 '15 at 16:47

    This is apparently a not uncommon issue in Aveos. .Some people report that pushing the shifter , in some cases to the left while removing the key works. – mikes Aug 3 '15 at 20:06
