My wife seems to be affected by the same problem all other fx owners on here are affected by. she can not get into her car without the use of her key. it is terrible to pay that much for a car and have to stand in the rain fumbling with your keys. both driver side doors are affected. i am unaware if temperature is the cause like some others feel. we live in texas where it is always over 85, so i cant do that study. i hope that infinity is going to do something about this. *tr
