The same thing happened to me, on separate time periods, for two different reasons. The good thing is that its easy to check and easy to rule out as one of the problems.
The first problem was due to the contact terminal on the driver's door switch coming loose. I couldn't visually tell it was loose, but I found looseness when I tightened the screw. Problem gone.
A year later the same symptoms returned but the door switch was fine. Turned out the door lock latch has worked its way loose and the door did not close all the way, causing the door switch to activate.
It could be one of these two problems on either the driver's door, or the left passenger door, but your dash indicator light should have told you which one.
Because it happens with the centrifugal force created on a right turn, I'm sure its has to do with the door switch, in one manner or another. If your car is parked and locked, and the switch activates from being loose, the alarm will think it was an intruder opening the door from smashing the window or a slim jim. Also, if the switch is activated while you are driving with the door locked, the computer will think you parked the car, left the key in the ignition, and had just locked yourself out of the car, initiating an automatic unlock signal from from the computer. To understand what I mean, open your driver's window, leave the key in the ignition but in the off position (actually any position will do), lock the door and then close it. You will see that the lock will immediately pop back up.
When you came out from the house to find that the doors had unlocked itself and the alarm was sounding, I have some ideas but I first need to know how you usually secure your MDX; manually lock the doors, use the remote key fob, or both (I know what some of your are thinking, but you never know).
The door switch is the black plastic plate with a rubber boot, and the door lock latch is the silver u-shaped bracket, make sure both are tight.
