The contact owns a 2009 Nissan Murano. The contact stated that upon the depression of the brake pedal, additional brake pedal travel time would be required to stop the vehicle as the brake pedal would depress to the floorboard. The contact described the brake as feeling "spongy" upon depression and that no warning light was illuminated on the instrument panel. The contact initially contacted an independent mechanic who bled the brake lines; however, the failure persisted. The contact then called the dealer who linked the failure to NHTSA Campaign Number: 18V916000 (Service Brakes, Hydraulic) however, the contact was given an estimate for a diagnostic. The manufacturer was also notified of the failure and referred him back to the dealer for assistance. The dealer agreed to repair the vehicle under recall; however, the failure remained. The contact then took the vehicle to another independent mechanic who repaired the brake master cylinder and the brake booster; however, despite these repairs, the failure persisted. The manufacturer was called back and offered no assistance. The vehicle had yet to be repaired. The failure mileage was approximately 200,000.

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.

Official recalls
4Dec 19, 2018
Nissan of North America, Inc (Nissan) is recalling certain 2009 Murano vehicles. The valves within the ABS Hydraulic Control Units (HCU) may react with brake fluids containing specific corrosion preventative additives. This reaction may cause the valves to not close properly.
Consequence & remedy
Consequence: If the valves do not properly close, additional brake pedal travel may be required to stop the vehicle, increasing the risk of a crash.
Remedy: Nissan has notified owners, and dealers will flush the brake system with DOT 4 fluid. The HCU will then be tested to detect a possible stuck valve condition. If necessary, the HCU will be replaced, free of charge. The recall began February 7, 2019. Owners may contact Nissan customer service at 1-800-867-7669.

Opened Apr 18, 2018 · Closed Jan 17, 2023
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip
On April 18, 2018, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA) 18-001 to investigate reports of braking concerns in model year (MY) 2009 Nissan Murano vehicles. A failure of the hydraulic control unit (HCU) portion of the antilock brake system (ABS), which involves improper operation of an internal hydraulic control valve(s), can cause extended brake pedal travel and may result in a reduction in overall braking effectiveness. Tier-one supplier Continental manufactured the HCU for Nissan.The corrosion-preventive, zinc coating used on the armatures of the normally closed (NC) valves within ABS HCU may react with brake fluids lacking sufficient corrosion-preventative additives. This reaction can cause the formation of a gelatinous material, which may cause the NC valves to close slowly. Over time, the gel can solidify to an extent such that the spring used to return the valve to the closed position may not be able to overcome the gel buildup, allowing the NC valve to remain open. If any of the four NC valves remains open, fluid will be diverted to one or two accumulator(s). This misdirected fluid has the net effect of causing brake pedal travel to increase, however enough stroke remains in the pedal to generate braking force. Although the hydraulic braking system remains intact and full braking force is maintained once the pedal travels the additional distance, when this condition occurs, the initial increase in brake pedal travel could result in increased stopping distance. An existing Nissan Service Campaign was launched for MY 2009 vehicles built prior to 11/1/2007. After consultation with ODI as part of EA18-001, Nissan decided to expand this population to the full range of MY2009 Murano vehicles. Later Murano vehicles exhibit significantly lower rates of malfunction.During this investigation 156 complaints were identified that related to the braking concern. Within the complainants 2 allege crashes with 4 injuries. The Nissan reports from investigation Information Request letter responses, were similar in content and identified 870 reports with 16 crashes and no injuries.On December 19, 2018, Nissan notified ODI it would conduct a safety recall (18V916) to remedy the ABS modules on certain MY 2009 Nissan Murano vehicles. The remedy procedure involves dealers flushing the brake system with DOT 4 fluid. The HCU will then be tested to detect a possible stuck valve condition. If necessary, the HCU will be replaced. The 2010-14 Murano SUVs outside the recall population and equipped with zinc-coated armatures will be inspected under a service campaign P0A08 using the same procedure as recall 18V916.Continental HCUs with a redesigned armature coating were phased into new vehicle production after December 2014 and do not appear to be experiencing corrosion. The recall action initiated by the manufacturer appears to address the safety risks of concern to ODI. Accordingly, the investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or MY vehicles outside of the recall scope. The agency reserves the right to take further action if warranted by the circumstances.For a complete summary of this investigation and related consumer complaints, please see attached closing resume document.

The Office of Defects Investigation (ODI) is closing this Preliminary Evaluation and upgrading to an Engineering Analysis (EA) 18-001.During the PE, ODI requested and reviewed information provided by Nissan including consumer complaints and other field and technical data related to failures of the hydraulic control unit (HCU), an electro-mechanical brake system component that provides antilock braking and other functionality in the subject model year (MY) 2009 Murano.The subject failure of the HCU, which involves improper operation of an internal hydraulic control valve, can cause extended brake pedal travel and may result in a reduction in overall braking effectiveness.Tier-one supplier Continental manufactured the HCU for Nissan.ODI currently recognizes 484 subject vehicle complaints that appear related to the alleged defect.Fourteen crash allegations, with three non-life threatening injuries are under evaluation also.ODI has been monitoring consumer complaints received, and in some cases has obtained suspect HCUs from complainants' vehicles.Recovered HCUs sent to NHTSA's Vehicle Research and Test Center (VRTC) in East Liberty, Ohio are under evaluation, and VRTC has conducted limited vehicle testing also.In a July 28, 2017 submission, Nissan acknowledged that a failure of the HCU can result in increased brake pedal travel during braking.Nissan's analysis of returned parts revealed that a zinc coating used on the normally closed valve assemblies inside the HCU may react with certain brake fluid constituents.The reaction results in the formation of a gelatinous material that can harden with time and prevent the valve from closing after opening in an ABS event.When this occurs, Nissan maintains that the hydraulic brake system remains intact and that full braking is available once the pedal travels an additional distance, about 36 mm according to Nissan.Although still under investigation, Nissan states it has not determined the condition represents an unreasonable risk to motor vehicle safety, citing low rate and vehicle age as additional factors.In March 2018, Nissan began conducting a customer satisfaction campaign on certain MY 2009 Murano to service (flush and replace the brake fluid), and then test and replace the HCU as needed.The campaign is being conducted free of charge to customers.During the EA, ODI will request VRTC continue to evaluate the cause and consequence of HCU failures, including the affects of multi-valve failures.ODI will further study the potential scope of the alleged defect as it understands similar HCUs and brake fluid is used in other MY Muranos, and potentially in other Nissan models as well.ODI notes that improved valve coatings were introduced on Nissan HCUs at some subsequent stage.
