The botton behind the door handle on the drivers door doesn't seem to be working. While the car is locked, walking up to the door and pressing the botton to unlock the car, works half the time. The whole door handle was replaced under warranty. That fixed it for about a day. Now it's still acting up. Do you guys think it could be the key fob going bad? Again it's like -2 here in Denver. Any input please.

 

You need the door sensor replaced common issue i just had my car at the dealer for this. I had mine replaced twice same issues worked for a day then when out again.

 

I agree with rust bucket, I had the same problem and since I had the sensor replaced it's been good.
