I have an 11 and it is a great system but dont try to fool the system. You have said some things that do and dont make sense. The Jeep can drive straight and the wheel can be turned a half turn in one direction or the other. Pictures this, the system is designed so when you are entering a turn at speed if the wheel is so far past the extreme of where it should be the vehicle is trying to save your life by shutting down the speed etc.
You need a good mechanic that understands alignments and how alignments play such a major role with this safety feature. He should he able to fix it in 15 mins while you wait if he knows what he is doing.
You did not say if the wheel was straight you only said the vehicle drove straight. Big difference and big problem in this product. In the future no super secret stuff, that is what is probably making you say belles and whistles. It is a quite simple vehicle and actually does a great job with the stop gaps it has. Tricking a computer, not good if you want something to run right.
Only time I had a similar thing happen my mechanic did a quick half assed alignment because a huge snow storm was coming. And dont let the old solid axle so there is only toe from the old school days fool you either, toe and castor are a huge part of the performance, death wobble, and a couple other wierd things that happen. If you have a long arm make sure you check the rear also.
