NHTSA Complaint #10450846 — 2002 GMC YUKON DENALI

BRAKES FAILED DUE TO CORROSION OF THE BRAKE LINE. BRAKING WAS NOT EXISTENT AS THE PEDAL TRAVELS TO THE FLOOR. THANK GOD FOR NOT BEING IN A BUSY STREET AND BEING ABLE TO COAST TO A STOP. THIS IS A HEAVY VEHICLE AND WITHOUT BRAKING ABILITY IT COULD EASILY KILL PEOPLE. AFTER ADDING SOME BRAKE FLUID (MOST OF WHICH LEAKED THROUGH THE BROKEN LINE) THERE'S NOT EVEN A WARNING LIGHT ON TO ALERT OF A BRAKING PROBLEM DESPITE THE FACT THAT THE PEDAL GOES TO THE FLOOR. THE OTHER IMPORTANT POINT TO NOTE IS THAT THE FAILURE IN THE LINE APPEARS TO HAVE HAPPENED IN A PART OF THE LINE THAT APPEARS TO BE INSIDE THE CAR FRAME WHICH MAKES IT THE MOST PROTECTED LINE FROM THE OUTSIDE ELEMENTS. IF THAT'S THE FIRST LINE TO FAIL, IT WOULD SUGGEST SUB STANDARD MATERIALS BEING USED IN MANUFACTURING THESE LINES. *TR
