So does anyone have a tally of the number of forum members (and/or other Mustang owners) that have experienced this phenomenom?

This is the second time I've heard of this but I'm not the most frequent forum member.

So far I'm the first one with this exact scary malfunction. Others have had some issues.

Hope that clears things up a bit.
Convert, here is my new hypothesis after playing this in my head over and over. I had just pulled over and got gas at a little Indian reservation gas station less than 3 miles prior to the first incedent of ESC freaking out. I switched lanes and accelerated to get around the rock truck, even though I never fill past the first click, could it have been so full that gas sloshed out, messing up the Left Rear sensor, the second time maybe just the residual gas with added 50mph wind in the wheel well? Both times the Right Front was the first brake I noticed slamming hard, the opposite corner.

Neither me or the dealer can duplicate the problem, and maybe putting this reason in my head just keeps me from being scared like a little kid everytime I accelerate on to the freeway. So maybe it's just a defense mechanism, but it's working. So, Possible or Defense Mechanism?

I don't think the gas can slosh enough to upset a wheel speed sensor.

Weird.

2011 Ford Mustang GT 5.0 - Short Take Road Test - Car Reviews - Car and Driver
Car & Driver quote:
What’s not better is the capless fuel port Ford adopted last year. The idea of getting rid of a fussy, hard-to-turn cap is great—except that we always seem to spill fuel on the car and on our shoes. And after some hard cornering on a full tank, we noticed signs of weeping down the Mustang’s quarter-panel where dust had collected in the dampness. Last year, Ford told us there was a problem with early filler necks and that it had been fixed. What does it have to tell us now?

C&D also had a picture of gas splashing out of the filler neck, while taking a hard corner. I can't find that now, but I saw it 2 years ago.

Wild guess question: are you driving past any high-energy RF or other kinds of high-energy sources, being AF, that might be messing with your electronics?

Only mention this because I read a story about someone a few years ago who was having weird (in their case) TPMS outages no-one could explain, and it was finally isolated to their passing by a high-energy radar installation near Chantilly, VA.

Unlikely in this case but just bringing it up on a chance.

I don't have the answer, but I'll poke wholes in theories. How could gasoline affect a wheel speed sensor differently than water?

Not 90 seconds before reading this KING 5 news brought up a story near Fort Huachuca were everyones key fobs in the town don't work now.
But I was between the coast and the Olympic Mts. on the Hoh Indian reservation. Yes pronounced HO. I doubt high power EM interference was in the Hoh rainforest.

And I don't know how Gas would interfere more than water. Just perplexed still.

I have not had a customer car behave quite like the OP's but have had plenty of similar issues. Usually what happens with something like a wheelspeed sensor fault is the ABS tries pulsing the brakes no matter how light you touch the pedal. This causes a severe reduction in the amount of pressure the driver can put into the brakes and indeed makes for a very dangerous driving experience.
Grimace?,
Can I pull a fuse so all electronic assist are off all the time?

Not advised as you would lose ABS at the same time. Not to mention a constant fault message in the instrument cluster.

Even if it were possible to 'tune out' the ESC the hardware will still be on the car and have the possibility to malfunction. But honestly, ESC is no more likely to cause a dangerous driving condition than any other component or system in the car. It's not like people go around replacing their fuel tanks with fuel cells in fear they will explode.

Grimace or Convert are these my driver's side rear wheel speed sensors, or tpms? Or maybe something else?

I might be misremembering but I thought there was a guy here in LA that had the same issue about a year ago. The first time it happened the dealer couldn't replicate the issue. So he tried to video tape it so the dealer would believe him. I think after the third time it happened the dealer just changed all the sensors.

I hope for all our sakes this doesn't become a common thing.

I think this is the guy I was remembering. It could be the same issue; only you would know the best from the experience.
