WHILE DRIVING MY CAR THIS MORNING MY BRAKES WENT ALMOST TO THE FLOOR BEFORE I COULD STOP THE CAR IN THE MIDDLE OF AN INTERSECTION. (SOFT BRAKE PEDAL). I WAS LUCKY I WAS NOT HIT BY A CAR. THIS HAS HAPPENED BEFORE. I RECENTLY FOUND OUT THAT THERE ARE MORE THAN 110,000 PEOPLE COMPLAINING ABOUT THIS ISSUE AND HAVING TO PAY A LOT OF MONEY TO TRY AND FIND THE PROBLEM TO NO AVAIL. NISSAN HAS TO KNOW ABOUT IT BUT WILL NOT ADDRESS THIS ISSUE. DOES IT TAKE PEOPLE SERIOUSLY GETTING HURT OR DYING TO GET THE ATTENTION OF THIS ISSUE? THIS ISSUE IS CONSIDERED A MATTER OF LIFE AND DEATH. WHO DO WE GO TO? DEALERS SAY THEY DON'T KNOW WHAT TO DO TO FIX IT AND NISSAN DENIES THIS IS HAPPENING.

I LOSE ABS BREAKING WHEN I RUN OVER A POTHOLE OR SLIDE ON ICE/SNOW. IT OCCURRED TWICE THIS WEEK. ONCE I WAS DRIVING AND I WENT THROUGH A STOP SIGN B/C I COULDN'T COME TO A STOP WITH THE BRAKES PRESSED TO THE FLOOR. A SECOND OCCURRENCE TOOK PLACE FOR MY WIFE WHEN SHE HIT A POTHOLE AND IT TOOK A SIGNIFICANT STOPPING DISTANCE TO COME TO A COMPLETE STOP. ONLY BY SHUTTING OFF THE ENGINE AND RESTARTING THE ENGINE DOES THE ABS SYSTEM AND THEREFORE THE BREAKS WORK AGAIN. THIS HAS OCCURRED OVER THE PAST 12 MONTHS AND WE HAVE HAD A FULL INSPECTION ON MY BRAKE LINING, ABS SYSTEM, FLUID PRESSURE, ETC AND EVERYTHING PASSES. WHAT SHOULD BE DONE TO CORRECT THIS ISSUE?

ALSO,THIS IS A VERY COMMON PROBLEM WITH ALL NISSANS - QUESTS DO HAVE A RECALL ON IT, BUT NO OTHER NISSAN, EVEN THOUGH THEY ALL USE THE SAME FAULTY GAS GUAGE. IT CAUSES PANIC TO THE DRIVER TO SEE THE "EMPTY" LIGHT ON, & THEY CALL FOR HELP, SWERVE OFF THE ROAD, WHEN THEY ARE REALLY NOT EMPTY AT ALL. ALL NISSANS SHOULD HAVE A RECALL ON THESE FAULTY GAS GAUGES SO THAT NISSAN DISCONTINUES USING THEM.

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.
