The power door locks lock and unlock themselves constantly while I'm driving. This happened originally at 12,000, stopped and now has started up again at 23,000. Dealer service says they can't figure out the problem (?). I hear a clicking noise from the steering column also when it happens, though now it's a constant instead of intermittent problem. Very bad thing when you have to drive small children around.

Door locks would repeatedly try to keep locking themselves. Replaced driver's side door lock actuator. Went with OEM part, Honda Part Number 72155-SV4-A21, $160.
The actuator mechanism has two rubber stops that eventually wear out or fall out of place and causes the malfunction. It is somewhat of a pain to access and replace. Trying to fix the unit by reusing the old rubber stops would definitively not make sense to me, since the unit would probably fail again in no time.
Removing the door panel
Disconnect the battery. There are mechanical and electrical connections to the door panel. Pry off the triangle shaped power door mirror plastic cover. With the glass window closed, remove two screws; one that secures the inner door handle and the other by the armrest. Pull the inner handle forward and out of the way and disconnect the inner handle rod and power door lock connector. Be careful as you do this because there will be several electrical connectors that will have to be unplugged before you can fully remove the panel. Working from the bottom, release the clips that hold the door panel. Once all clips are released, remove the door panel by pulling it upward. There is no need to remove the glass window. I have read how removing the glass window makes the actuator replacement process easier but I don’t see how that might be so. The actuator is located right under the door lactch mechanism. Slowly remove the left side of the plastic cover just enough to allow access to work area. The less adhesive you damage or remove the better, since you might be able to adhere the plastic back in place without having to apply new adhesive.
Removing the Actuator
Three screws hold the actuator in place. There is also a plastic cover that is held by one screw. Remove the bolt that secures the center channel in place (page 20-8). This will allow you to move the center channel out of the way in order to access the screws. Remove the plastic cover screw and slide the cover up. Remove the three screws that secure the actuator in place. The actuator will come right off. It is probably a good idea to apply di-electric grease compound to the electrical connector since this connector is exposed to some humidity.

My remote opens all the doors except the driver's side rear door. About a day after this occurred, this faulty door lock now makes a clicking noise whenever, I first stop, then pull off.

When I lock the doors, they lock and unlock themselves several times
The power door locks on my 2010 Honda Accord work intermittently. They lock at times but most of the time, they need to be manually locked. As a result, my alarm will not go on due to the faulty actuator. I have to go back inside my car, lock the doors manually, then step back and lock the door with the remote control. I took the car back to the dealer but the mnf. warranty ran out at 30K miles. I bought an extended warranty and just made it in time before that warranty ran out (60K miles). My deductible is $100 which I have to pay out-of-pocket. This should be a recall and Honda should pay for this repar!!!

Power door locks fails during winter & starts working normally in summer. Worked fine for the first 9 years. Has been happening for the last 3 years.

doors lock and unlock by themselves and will lock us in the car sometimes. When i go to get in my car in the a.m. the doors are usually unlocked even thougfh i know i locked them the night before.
My doors all lock and unlock intermittently as I drive down the road. There is no specific driving behavior that correlates with the locking. It's totally random, and comes and goes. I have a CODE ALARM aftermarket alarm system, but this problem only started happening recently after years of driving without issue.

Power Door Locks on three of the four doors have caused problems.
