Anyone have any issue with drivers door armrest? I have an 08 and I had my elbow leaned on it and it felt like it cracked or something . Just wondering if it's easy to get at that and fix it or is it a big ordeal and expensive

This is not a big deal... Your car is old... Accept it.... I've had plenty of Nissans through out my years and yes they tend too get a bit creaky and clunky through out time... Unless you really want to replace your door panel for a newer one than go for it and waste the money.....
