Doors Randomly Unlocking While Driving
This morning while on way to work, I must have been cruising at about 40 MPH, when all of a sudden, doors unlocked. Shortly thereafter I came to a red light, but once I took off, doors didn't automatically lock as they should when car is 9 MPH. Once I arrived to work, I manually locked doors using door buttons and they locked fine. I have not driven car again since this morning. Any ideas what could be the snafu!

May or may not be related but sometimes, if you hit a hard bump, the doors will automatically unlock because the vehicle may have detected an accident, more of a safety feature in case you needed to exit the vehicle in case that was an emergency.

I had that happen to me not too long ago, hit a really bad bump on the highway at speeds. Felt like the car might have bottomed out, the doors unlocked. First time it happened to me. It stayed unlocked and I just hit the lock button a couple minutes later.
