Fit power locks

I have a 2008 Fit, about 4 months ago I walked by my car in the driveway and I heard the power locks locking and unlocking non-stop. I took it right to the dealer where I purchased the car, all the way to the dealership the power locks were locking and unlocking. The mechanics could not find the problem and said if it happens again bring it back.
Today it happens again, but I was to far from the dealer to take back. After I shut off and started up the car a few time it stopped. My car is just power lock by key no remote.
Does anyone now what the problem might be??

The 2001 Prelude had a similar problem. Ask your mechanic to look up the following Technical Service Bulletin (TSB):

Date: 01/01/2002
Component Name: 162300 STRUCTURE:BODY:DOOR
NHTSA #: 010102
SUMMARY: INFORMATION ON POWER DOOR LOCKS THAT MAY LOCK BY THEMSELVES OR MAY CYCLE TWICE TO UNLOCK AND THEN LOCK THEMSELVES.

Honda tends to stick with the same engineering approaches across models and over time. The fix may be similar to the one used on the Prelude.

Hope that helps.

This problem also occurred on the Chevy Cobalt / Pontiac Pursuit / Pontiac G5.
There may be a sticking door switch.

Power Door Locks Cycling Or Inoperative From The Switches

Models: 2005-2008 Chevrolet Cobalt

2005-2006 Pontiac Pursuit

2007-2008 Pontiac G5 It has been reported that an issue exists that will cause the door locks to cycle when driving and/or
become inoperative from the door lock switches. When the condition is present the door locks are inoperative from the
switches, however they work normally with the key fobs. (If equipped with Remote keyless Entry)It is recommended that
you connect the Tech-2 to the vehicle and look at the door lock switch status (RFA data-list) it should be reading "Idle".
If it reads lock or unlock then check for a possible sticking door lock switch and replace as necessary. also found corrosion
at the power window switch on these vehicles.

You should check the door switches and door locks for sticking switches. You should also check for water leaks in the door,
wet wiring, shorts, or bare wiring. If the window does not seal well where it retracts into the door panel, water can get into
the door and cause problems. Even if it is not raining when you have the problem, water in the door can condense when the
temperature drops (or overnight) and cause the door locks to short out after the car cools down.
