It is because the door actuator is bad in those doors.
Replacements can be found at the dealership for around $60 or on Ebay for as little as $10. Number 5/24 in the diagram below. Actuator part # Left Side 72155-S5P-A11
& the Right side 72115-S6A-J01
Expect to set aside at least 1-2 hours on the first replacement, lesser time on the ones afterwards. Be careful not to push parts in directions that they shouldn't be pushed in. Don't break any plastic parts/metal rods or connections - take your time.
1. Remove the plastic tab under the inner door latch.
2. Open the 2 small black colored screws.
3. Carefully swing the door latch attachment out by moving it down and out. Remove the rod and the electrical connection - there's a slot to press and pull-out.
4. Use a flat screw driver to carefully pry the window opening plastic area (its one piece and includes the cup holder). Remove the electrical connection - there's a slot to press and pull-out. Open the screw beneath the arm rest.
5. Use a flat tool (I used a metal putty 5-in-1 tool) to slide between the door metal and plastic areas - pull the plastic buttons/connections off, you'll hear them pop. Slide the door out.
6. Gently open the white plastic sheet about a quarter of the way from the top right down so you can reach in the actuator area (near the door latch - at the end of door with 3 screws). Remove the window guardrail, if its in the way - use a 3/8 bolt.
7. Use correct amount of force, without stripping them, open the 3 screws at the door latch.(Best to use a Handheld Impact Driver
8. Take a good look at the connections inside. Disconnect the electrical connections (two of them) on the lock actuator.
9. Gently but forcefully (without breaking any plastic or other parts), push the metal connectors back and carefully remove the door lock actuator assembly from the door.
10. Replace with new actuator and assemble in reverse.
