OK my 2011 GT500 is having a very strange problem. The AdvanceTrac can come on under certain circumstances. When it comes on the car becomes basically undrivable. I would like to see if anyone else is having this problem.

It may be limited to 2011 cars with the electric power assist. But what happens is that as you drive down the road the ABS actuates the front wheels in an attempt to steer the car.

Here's how I got it to do it:

  • start the car
  • hit the traction control button twice to put the car in sport mode
  • drive a short distance
  • stop completely
  • turn the wheel at least one full turn and leave it there
  • put the car in 3rd
  • stall it out
  • let the car sit for a couple of seconds
  • without turning the car off, restart it
  • make a turn to the right and then straighten the wheel
  • after about 100-200 feet of driving straight the car should begin actuating the front brakes
To get the car to stop doing this you'll have to shut it off again.

Holly crap!! I cant help you but my suggestion is don't do that!

How in the world did you figure out that sequence?

Someone at Ford would probably be interested in knowing that sequence, as I'm sure it could possibly be tripping something in the software.

Well, I usually drive in Sport mode. I accidentally stalled the car out just before making a right turn. Fired the car back up, had to wait for traffic, then completed my right turn. After a few feet the car started activating the brakes and making all kinds of terrible noises. Had to pull over and shut the car off. It was almost undrivable and I think if you did it for any length of time you'd either overheat the brakes or wear them out in fairly short order.

Plus you can't really drive the car when it's doing that anyway. It pulls hard to one side each time it happens. It almost feels as if you're hitting a deep puddle and the car is being pulled to one side. I never went up to highway speeds to see how far up it would go. Didn't want to take a chance on crashing.

But it's not a totally implausible scenario. The test procedures sound more cumbersome than they really are, but I can't imagine I'm the only one who drives around in Sport mode.

Sport Mode is all I use unless I'm drag racing. it's worked flawlessly for me Chris... I had reservations about the '11 model and the "new stuff" like the steering and the coated block. Kinda glad I canceled the order and went with a '10 now...

Wow. That's totally plausible. If you were stopped about to turn right onto a freeway (I encounter this scenario every morning, sit at a stop sign about to turn right onto a 4 lane highway, speed limit 60) and turning and accelerating quickly to get up to speed, and it did it... that would be scary. Hopefully a resolution comes soon!

Were you able to test this?

Also just so you know if your car was built between April and August your EPAS system may have the active nibble cancellation turned off. Be sure to have your car checked for the latest TSB to fix this problem.

Hi Christopher,
I just got my shelby yesterday. I will test this out this week.

I will also check the build date of the car as well. Can you explain what the EPAS system issue is about?

Thanks!
Eric

The active nibble cancellation on the 2011 Shelby GT500 is turned off on cars produced between April and August. This can cause a vibration in the steering wheel at speeds of 50 MPH and up. The active nibble cancellation senses road forces acting on the tires and then applies opposite force to counteract it. This provides a smooth steering feel when driving down the road.

With active nibble cancellation turned off you may feel a vibration that closely approximates a wheel out of balance. This will get progressively worse as speed goes up.

The TSB to fix this issue is:
TSB# 10-16-4

It is simply a software re-flash and immediately took care of the problem I had been having with vibration.

chris i just got a 2011 but with the weather i havent been able to drive it except for the drive home from dealer...but here's my info my best friend has a 2010 ford f150 his truck is doing this but without the stalling, he has had it back 6 times infact he picked it up tonight from the dealer, they think its in the computer he had the manager of dealer in it driving down the highway and the brakes just lockup on thier own,, ford is baffled, the mechanics have no idea to fix it, its the only one they have seen so far..he is lemon lawing the truck.. it could be a glitch in the sensor or computer from ford...its very weird and i hope they figure it out cause i basically dumped my life into buying this car i def do not wanna go thru that...
