My outside door handle button started sticking and would not release. I had to tap on the door handle to get it to release.
It was an easy fix.
Go buy a spray can of white lithium grease that comes with a spray tube. (I like CRC)
Open the door and leave it open.
Unsnap the side of the inside door panel on the side towards the door handle. Also unclip one on the top and on the bottom. Be careful doing this so you dont' rip the cardboard of the door panel from the clips. This should allow the door panel to be pulled back a little bit.
Roll up the window.
Pull back the door panel a little and place a flashlight inside the door pointing up so you will be able to view the door handle assembly.
Shake the can of the white lithium grease and install the spray tube.
Do a test spray in your trash can.
Now lay on the ground looking up into your door while pulling the door panel back a little.
You will see the door lock/latching system.
Aim the spray nozzle to spray that lever that is located above the push button. Put the white lithium grease on heavy.
Push the button to see if it's fixed. I am sure it is.
Push the button in multiple times to work some grease into the pivots. Spray it again.
Now remove the flashlight and re-attach the door panel. Make sure the door panel clips are partially started into the holes of the door before you pound on them.
Done!
