Not sure if this is normal or not. If I leave the LC in the garage for three or four weeks with the doors locked (or unlocked - I've tried both), the battery (only six months old) keeps discharging completely. Does the security system draw THAT much power, or should I start looking for some other source of the battery drain? I recharged the battery the first time it happened and drove to AutoZone to double check the battery and was told it was still perfect.
