Did all of your interior lights come on as well? If so, you tripped it into rollover mode. I did it once on a hard corner with a bad bump in it. The yaw sensor will sense if it thinks a rollover is imminent and unlock the doors and turn on the lights. If it just unlocked the doors, then it was just a funky gremlin.

I've seen at least one other person here complain about the same thing (and he was immediately accused of being crazy/stupid/wrong), and I've had it happen to me once.

The one thing that I found that we had in common was that we were corning rather enthusiastically, and hit a bump while cornering.

Coincidentally, the other person was also exiting from a freeway (late for the ramp, so he yanked the wheel - and hit a small bump). My experience occurred hustling around a 90 degree turn, when the inside rear wheel dropped off of the pavement. It wasn't a big, jarring, jolt . . . but it was enough to cause the doors to unlock enexpectedly.

I don' t know if this is due to the rollover/accident feature, or if there is simply a place in the circuit that can short when hitting a bump while cornering.

Either way, it hasn't happened since, so I don't think that it's a major deal (with my car). If it happens to you repeatedly, then I'd have the dealer check it out.

it was probably a glitch, i've had a few in my car. if it happens again, go to the dealer and have them clear all the fault codes. When i was having problems with my sunroof and windows, i had my father clear all the fault codes and everything went back to normal.
