THE ISSUE WITH MY NISSAN MURANO IS THE LOCK ACTUATOR BEGINNING TO GO OUT. IT STARTED IN MAY WHEN THE KEY FOB BEGAN NOT WORKING. WE STARTED HAVING TO UNLOCK THE VEHICLE WITH THE KEY AND THEN UNLOCK THE OTHER DOORS WITH THE BUTTON ON THE DOOR. THIS WAS FINE UNTIL THE LOCK ON THE DOOR BEGAN TO FAIL. IT WORKS OCCASIONALLY BUT NOT ALL THE TIME. THIS IS MY WIFE'S CAR AND WE HAVE ONE CHILD AND ANOTHER ON THE WAY, AND SHE WILL BE USING THIS VEHICLE TO TRANSPORT TWO KIDS WHILE I'M AT WORK. IT'S A SAFETY ISSUE BECAUSE DURING INCLEMENT WEATHER MY WIFE CAN'T PUT OUR BABY ON THE GROUND TO UNLOCK ALL THE DOORS AFTER THE ACTUATOR COMPLETELY FAILS. NOT ONLY FOR THAT REASON IS IT A SAFETY HAZARD BUT JUST BECAUSE A FIRE HASN'T OCCURRED YET BECAUSE OF THIS ELECTRICAL ISSUE DOESN'T MEAN THAT ONE WILL NOT HAPPEN. AS A FATHER THIS IS SOMETHING I HAVE TO BE CONCERNED WITH. *TR

WE WERE DRIVING AND THE CAR LOST SPEED. WE HAD THE CAR TOWED TO THE NISSAN DEALER AND THEY DIAGNOSED THAT THE BATTERY HAD FAILED. THIS WAS THE SECOND NEW BATTERY. THEN, THE CAR RAN UNTIL THE BATTERY WENT DEAD AND AGAIN THE CAR STOPPED ON THE ROAD IN TRAFFIC WITHOUT WARNING. AGAIN THE CAR WAS TOWED TO THE NISSAN DEALER AND THIS TIME THE PROBLEM WAS DIAGNOSED AS A BAD ALTERNATOR. QUESTIONS BOUGHT UP THAT THE 2008 NISSAN MURANOS HAD A CAMPAIGN TO REPLACE FAULTY ALTERNATORS BUT NOT THE 2009. PROBLEM IS THAT WITHOUT WARNING LIGHT ON THE DASH THAT THERE IS A PROBLEM WITH THE CHARGING SYSTEM, THE CAR BATTERY GOES DEAD AND THE CAR STOPS WHILE DRIVING. THE RISK OF CATASTROPHIC ACCIDENT IS EXTREME. *TR

BOTH FOBS (CAR KEYS) WENT BAD ON MY 2009 NISSAN MURANO, UNABLE TO LOCK AND OPEN DOORS USING THE FOB. I HAD TO REMOVE THE KEY FROM THE FOB TO UNLOCK THE DOORS. AT NIGHT THIS WAS A SAFETY ISSUE AS I HAD TO STRUGGLE TO TAKE THE KEY OUT OF THE CASE IN THE DARK. REPLACED BATTERIES IN THE FOB AND DID NOT RESOLVE THE ISSUE. ON JANUARY 22, 2014 I MAILED A LETTER TO NISSAN OF AMERICA ASKING FOR REIMBURSEMENT OF THE NEW FOB I HAD TO PURCHASE. NISSAN WAS UNABLE TO OFFER FINANCIAL ASSISTANCE WITH THE REPLACEMENT OF THE FOB AS THE VEHICLE BEING OUTSIDE OF THE NEW VEHICLE LIMITED WARRANTY. AS I EXPRESSED MY CONCERN TO NISSAN THAT A CAR KEY SHOULD NEVER HAVE TO BE REPLACED. THESE FOBS ARE MANUFACTURING DEFECTS I UNDERSTAND REPLACING A BATTERY BUT NOT THE ENTIRE FOB.

OUR VEHICLE IS A 2009 NISSAN MURANO SL WITH RELATIVELY LOW MILEAGE. AROUND NOVEMBER OF 2010 THE DOOR LOCK ACTUATORS BEGAN TO RANDOMLY FAIL TO WORK ON THIS VEHICLE. OVER A PERIOD OF SEVERAL MONTHS THE MALFUNCTIONING DOOR LOCK ACTUATORS SPREAD TO ALL FOUR OF THE DOORS ON THIS CAR. I HAVE CONTACTED TWO DIFFERENT DEALERSHIPS AFTER HAVING LEARNED THAT THIS IS A VERY COMMON FAILURE ON MULTIPLE YEAR MODELS OF NISSANS. BOTH DEALERS EXPLAINED THERE WAS NO RECALL AND THAT THE REPAIRS WOULD LIKELY RUN $1200 TO $1800 TO FIX ALL FOUR DOORS. LIVING IN THE HOUSTON AREA AND HAVING A GRANDCHILD, THIS IS AN EXTREMELY DANGEROUS SITUATION. NISSAN SHOULD BE REQUIRED TO RECALL THE VEHICLES SUFFERING FROM THIS DEFECT. OTHER VEHICLES THAT I HAVE OWNED FOR MANY YEARS NEVER SUFFERED A FAILURE OF SUCH A CRITICAL COMPONENT. THE PRICE DEALERS ARE CHARGING FOR THIS REPAIR IS OUTRAGEOUS IN LIGHT OF THE FACT THAT IT IS SO CRITICAL TO SAFETY. THE INABILITY TO QUICKLY AND SAFELY LOCK A VEHICLE INVITES OCCUPANTS TO BE EJECTED IN THE EVENT OF A CRASH AND MAKES OCCUPANTS OF THE VEHICLE MUCH MORE VULNERABLE TO CAR JACKING OR OTHER FORCED ENTRY CRIMES. PLEASE LOOK INTO THE FREQUENCY AND SEVERITY OF THIS ISSUE AND FORCE NISSAN TO ACKNOWLEDGE THIS VERY SIGNIFICANT DEFECT IN THEIR VEHICLES. *TR

18V916000 · Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module

Dec 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.

EA18001 · 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.

Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Air:antilock; Service Brakes, Air:antilock:control Unit/module

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.
