I was watching for it and it happened to me at least once.
Nothing too serious on my part. Harley, Try turning the auto stability
control off.

For those of you familiar with CPU's it probably has to do with type
of processor being used in the car not being real time. In other
words the exact
time it takes the processor to complete an instruction is indeterminate.

The Motorola 68000 had a 32 gig linear address space while the
Intel processors
had a "paging" address space. We used to call it by its real name
in the old days. Nasty "bank switching" :) If the program crossed a page
boundary strange things could happen time wise.

The RX8 processor is very powerful with a lot of stuff in there including
two separate network protocols. OBD II and CAN.

Paul...I have the cheap model <G>.  I don't have the stability
control...just the electric assist steering.  From what I've researched on
that type, it appears that Mazda uses an NSK or Toyo manufactured front
end...complete from the steering column down to the wheels...with it's own
ECU.  Which makes the possibility of some kind of interaction even more
weird.

I was going to pull the fuse for the system and see what that does, but the
only one I could find that remotely resembled a steering unit fuse was one
marked ABS/DSC.  That definitely stopped the ABS system from working (and
turned the brake light on), but since I don't have stability control, it
probably didn't do anything to that....at least it didn't feel like it.
After pulling the fuse, I was still able to get it do the uncommanded
turning.

We'll see what others have to say, and what Mazda says, or does.
