NHTSA Complaint #10567250 — 2009 NISSAN MURANO

AFTER STARTING FROM A COLD START (PARKED OVERNIGHT) I NOTICED THE BRAKE PEDAL WAS SOFT AND WENT ALMOST TO THE FLOOR. THERE WAS NO PRIOR SIGN OF BRAKE FAILURE AND THE CAR STILL COULD STOP, JUST NOT AS QUICKLY OR FIRMLY AS NORMAL. CAR WAS TAKEN TO A REPAIR SHOP WHO DIAGNOSED A LEAKING MASTER CYLINDER BUT THERE WAS NO BRAKE FAILURE WARNING LIGHT. AFTER THE SHOP REPLACED THE MASTER CYLINDER AND BLEED THE SYSTEM THEY FOUND ANOTHER LEAK IN THE ABS CONTROLLER/ECU MODULE. AN INTERNAL LEAK, AND NO REPAIR IS POSSIBLE. THE SHOP SAYS THEY HAVE SPOKEN TO NISSAN AND LOOKED ONLINE BUT FIND NO INFORMATION ABOUT OTHER SIMILAR BRAKING SYSTEM FAILURES, NO TSB'S, NO RECALLS. I FIND IT VERY DISTURBING THAT TWO CRITICAL BRAKE PARTS COULD BOTH BE LEAKING AND FAILING, AND THE CAR SHOWED NO BRAKE WARNING LIGHTS, NO ABS WARNING LIGHTS, NO INDICATION OF ANY PROBLEM WHILE THE BRAKES HAD OBVIOUSLY ALREADY FAILED. THIS IS A FAIRLY LOW MILEAGE SINGLE-OWNER VEHICLE WHICH HAS NOT BEEN IN ANY ACCIDENTS AND HAS BEEN MAINTAINED PROPERLY. THE FAILED PARTS (BRAKE MASTER AND ABS CONTROLLER/ECU ARE BEING HELD AVAILABLE FOR INSPECTION.
