I have the same issue with mine, Limited, 4x4 offroad, Air. Scared the crap out of me when I slammed on the brakes going 70 mph and almost ended up hitting a car on my right. Took it to a dealer, they acknowledged it pulls to the right while braking hard at highway speeds, but couldn't find anything wrong with it. Their recommendation was to drive it for several thousand miles to brake in my Nitto Grapplers, which are causing the problem in their opinion. Another dealer's fairytale?
