WHEN APPROACHING A RED LIGHT ON A LOCAL ROAD, MY VEHICLE SLOWED DOWN BUT DID NOT COME TO A COMPLETE STOP. THE BRAKE PEDAL PROVIDED NO RESISTANCE AND THEREFORE WAS APPLIED TO THE FLOOR OF THE VEHICLE. AS A RESULT, MY CAR PASSED THROUGH THE INTERSECTION AT APPROXIMATELY 10MPH. UPON IMMEDIATE INSPECTION BY A TECHNICIAN, THE BRAKE FLUID WAS FLUSHED AND REPLACED WITH DOT 4 FLUID. THREE MONTHS LATER, THE SAME ISSUE OCCURRED WHILE ON THE HIGHWAY. THE BRAKE PEDAL LACKED RESISTANCE, WAS APPLIED TO THE FLOOR OF THE CAR, AND THE CAR DID NOT COME TO A COMPLETE STOP UNTIL IT WAS TURNED OFF WHILE ON THE HIGHWAY AT A SPEED OF 10MPH. UNDER A NISSAN BRAKE FLUID SERVICE CAMPAIGN, THE BRAKE FLUID WAS ONCE AGAIN FLUSHED, REPLACED WITH DOT 4 FLUID, AND ABS WAS INSPECTED. DEALER WAS UNABLE TO IDENTIFY THE ISSUE SINCE THE INSPECTION PASSED AND STATES THE ABS WAS MOST LIKELY ACTIVATED IN BOTH INCIDENTS WITHOUT CAUSE. NO FURTHER EFFORT IS BEING PROVIDED. UPON FILING A CASE WITH NISSAN CONSUMER AFFAIRS, NISSAN IS UNABLE TO REPLACE THE ACTUATOR PER THE SERVICE CAMPAIGN SINCE TESTS PASSED AND DEALER IS UNABLE TO REPLICATE SCENARIO. NISSAN AND THE DEALER ARE BOTH UNABLE TO IDENTIFY THE ISSUE AND UNWILLING TO PROVIDE ASSURANCE THAT THE BRAKES ARE SAFE TO OPERATE. THEY CONCLUDED TESTING PROCEDURES WERE FOLLOWED AND HAVE NO ADDITIONAL STEPS TO BE TAKEN. THIS IS UNACCEPTABLE IN TERMS OF NOT IDENTIFYING WHY THE ABS WAS ACTIVATED WITHOUT CAUSE AND SUBSEQUENTLY PUTTING CONSUMER LIVES AT RISK. AFTER 2 DANGEROUS INCIDENTS AND POOR CUSTOMER SERVICE, I LACK CONFIDENCE IN THE NISSAN BRAND, WILL NOT PURCHASE AGAIN AND WOULD ADVISE OTHERS OF THE SAME.

MY 2099 NISSAN MURANO HAS 67,000 MILES, 2 DAYS AGO WHILE TRAVELING HOME FROM A LOCAL STORE IN THE RAIN TRYING TO STOP AT A STOP SIGN THE BRAKE PEDAL WENT COMPLETELY TO THE FLOOR AND BRAKES DID NOT WORK. THE CAR WENT INTO THE INTERSECTION, THANKFULLY NO OTHER CARS WERE COMING. BRAKE PEDAL CONTINUES TO GO TO THE FLOOR, CAR DOESNOT STOPS UNTIL STANDING ON THE PEDAL PUSHING IT COMPLETELY TO THE FLOOR. TOOK IT TO MY MECHANIC, HE DRAINED THE BRAKE LINES TO GET RID OF ANY AIR AND PUT IN NEW BRAKE FLUID. DID NOT HELP. HE THEN TOLD ME TO LOOK AT THE COMPLAINTS AND OPEN INVESTIGATION ABOUT THE MANY 2009 MURANO HAVING THIS SAME PROBLEM AND ALL THE MONEY OWNERS HAVE SPENT TO TRY TO FIX THE PROBLEM WITH NO GOOD RESULTS. I ALSO CALLED THE NISSAN DEALER AND THEY SAID THEY NEVER HEARD OF ANY PROBLEMS WITH THE 2009 MURANO. I AM THANKFUL MY MECHANIC DID HIS HOMEWORK. BUT NOW I AM STUCK WITH A $275.00 A MONTH PAYMENT FOR A CAR THAT IS NOT SAFE TO DRIVE AND NOBODY, EVEN THE NISSAN DEALERS ADMIT THAT THERE IS A TRUE PROBLEM OR DEFECT AND NOBODY KNOWS HOW TO FIX IT. WITHOUT YOU ADMITTING THERE IS A DEFECT AND REQUIRING A RECALL IS FORCING PEOPLE TO CONTINUE TO DRIVE THESE CARS WITH FAULTY BRAKES. I JUST HOPE IT DOES NOT TAKE A DEATH OR TWO FOR THIS DEFECT TO BE RECALLED BECAUSE WITH ALL THE DOCUMENTED ISSUES BEING BASICALLY THE SAME AND YOUR INVESTIGATION BEING OPEN FOR OVER A YEAR I AM SURE MANY PEOPLE WILL BE OPENING LAW SUITS IF DEATH OR INJURY OCCUR. THIS IS A SERIOUS SITUATION AND THESE CAR OWNERS DESERVE MORE THEN WHAT THEY ARE RECEIVING FROM YOU AND NISSAN. TIME TO STEP UP AND FIX THIS BEFORE ANYBODY ELSE GETS HURT OR ANY DEATHS OCCUR. YOUR NOTE SAYS TO RETAIN ANY DOCUMENTATION FOR 5 YEARS, WELL IN 5 YEARS THESE CARS WILL BE14 YEARS OLD AND SEEING THAT THIS PROBLEM SEEMS TO START AROUND 65,000 MILES, THIS NEEDS FIX NOW!

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.

2EA18001 · Extended Braking Distances
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.
