AS I AM A AUTO TECHNICIAN FOR CHRYSLER AND NOT HAVE SEEN SUCH RUST ON BRAKE LINES UNLESS VEHICLE HAS 200,000 MILES OR SO.THIS VEHICLE ONLY HAS 36,000 MILES .I FEEL THAT THE MATERIAL THE LINES ARE MADE OUT OF ARE INFERIOR RAW MATERIALS. I HAVE REPLACED THE LINES THAT WERE LEAKING AND PLAN TO REPLACE THE REST AT SOME TIME MAKING THEM MY SELF WITH SOMETHING THAT MAY HOLD UP BETTER TO MY SEAT BELT LOCATION.WITH THAT SAID IF GENERAL MOTORS DECIDES TO WAKE UP AND RECALLS THE BRAKE LINES I WOULD APPRECIATE SOME RESTITUTION,I NOTICED LIKE ME MANY PEOPLE HAVE EXPERIENCED THE SAME ISSUES AND HAD THERE VEHICLES REPAIRED AND WERE REIMBURSED FOR THEIR TROUBLES. *TR
