While braking at low speeds and coming to a full stop, truck lurches forward and brake pedal goes down 1/8 of an inch. Driver must use more brake to stop truck ( this is with no load in truck at all, only passenger ). Also while stopped and turning the wheel left or right to park, steering wheel looses power steering until brake is released and truck starts rolling. Had truck looked at twice before at dealer for same problem ( once at 32,000 and again at 35,000 ) and was told, as long as no hard codes or failures are found, they were unable to address the issue.
