Random door ajar light
Occasionally when turning a corner, my door ajar light will quickly come on, chime and then go off while driving my 2012 Crew Cab. I have open and closed all doors ensuring they are closed tight, yet it still occurs. I only recently was able to quickly see the door ajar light coming on and could not tell if it referenced a specific door. Any thoughts on what to check? As mentioned it only happens while turning a corner.

Does the door rattle on bumps? Sounds like there is enough play in the door that the door switch is thinking the door is open, due to movement, on turns. If it happens when you turn left, then check the gaps on the left door. When driving straight and you put pressure on the door, do you hear a change in the air noise?

Does it happen when turning left or right?
If left, it's probably a right side door that has the problem. If right, it's probably a left side door that has the problem.
Now, have someone sit in the truck with the transmission in Drive and the windows rolled down on your suspect doors. pull on each suspect door and see if it sets off the door-ajar warning.
