Door Handle Sticking
It feels like the door is locked and you just have to pull a little harder to get it open.. Not really a huge deal, but it can be a pain in the a** when you're tired.
Cause - Lack of lubricant in the handle to ease it while opening,
Easy Fix - Pull the interior door panel off and lube it.
You'll get that low pitch rumble a bit like any other car.
Cause - No idea, unusualy fast wear.
Fix - Get a new one and put it on.
