I remember reading that staggered tire setups can cause the EPAS to freak out. Is that not the case here?

Lots of folks run staggered tires with no ill effects. I have staggered tires and 9" front rims, and 10" rear rims and my EPAS is fine. Could be luck-of-the-draw on EPAS failure or out-of-spec over time.

Grim, that was the exact description I told the shop foreman, then he took it out for a test drive himself...when he returned he said "I completely understand the term vagueness... almost a "dead spot" going in a straight line.
Light input corrections to the steering, were, well, dead...
I had no shake at all, but there was a definitive weirdness within the steering, like I was not connected to the actual rack. Alex is a hell of a mechanic, guess it's why he is the shop foreman.
Before he became SF he was the resident steering tech guy at the dealer.
Glad my issue is resolved... car is back to how it used to be, before this s*it reared it's ugly head.

I wonder if you can steer the car if EPAS totally fails. The steering shaft is still physically connected right? With hydro steering at least you can steer the car if it goes out, not sure about electric. Is it attached or is it like a playstation wheel?

It would be good to hear whether this issue gets resolved and how it was done, if I cannot resolve mine first.

I know, I know...this is the GT forum. Still have a similar issue.

Hey guys,

Bring them back in and let me escalate this for you again.

I took it to my dealer, and they replaced the EPAS rack...steering is now back to how it felt when it was brand new.
This was my particular case, and it was resolved.
Thanks for the update, 5.0 Candy REDCS!
