Loses power when accelerating

On December 13, 2023, the Office of Defects Investigation (ODI) opened PE23-023 to investigate allegations of engine failures leading to loss of motive power in model year (MY) 2021-2023 Nissan Rogue; MY 2019-2021 Nissan Altima; and MY 2019-2021 Infiniti QX50 vehicles. At that time, ODI had received 6 Vehicle Owner Questionnaires (VOQ) and multiple early warning reports, with consumers reporting engine knocking noises accompanied by a loss of engine power while driving. The investigation identified bearing failures in certain vehicles equipped with the subject 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines. ODI also identified early warning reports describing thermal incidents that occurred immediately after the vehicle suffered a catastrophic engine failure. The failures were the result of a manufacturing defect in specific engine bearings (main, A-, C-, and L-link) or other engine components that may cause engine damage and potentially lead to engine failure. Engine failure can result in a loss of motive power event that can increase the risk of a crash. Engine failure might also result in a fire if internal components detach and impact the engine block creating a hole that allows engine oil to reach hot surfaces. In its April 2024, May 2024, and June 2025 responses to ODI’s information requests, Nissan provided 998 customer reports (including complaints, field reports, and legal claims) and 1,107 warranty claims related to the allege

NISSAN NOTIFIED THE AGENCY ON JUNE 18, 2007 THAT IT WILL RECALL (RECALL # 07V267) ALL MY 2007 ALTIMA VEHICLES WITH 2.5 LITER ENGINE BUILT AT THE SMYRNA, TENNESSEE PLANT FROM SEPTEMBER 25, 2006 TO MAY 11, 2007 AND AT THE CANTON, MISSISSIPPI PLANT FROM OCTOBER 30, 2006 TO MAY 11, 2007.NISSAN DETERMINED THAT IF A SUFFICIENTLY HOT OBJECT (FOR EXAMPLE, A CIGARETTE ASH OR OTHER IGNITION SOURCE) ENTERS THE AIR FILTER HOUSING THROUGH THE ENGINE FRESH AIR INTAKE SYSTEM AND CONTACTS THE AIR FILTER, THE FLAMMABILITY CHARACTERISTICS OF THE AIR FILTER MATERIAL ARE SUCH THAT THE FILTER MAY IGNITE.IF THE AIR FILTER IGNITES, A FIRE MAY OCCUR.VEHICLES BUILT AFTER THESE DATES ARE EQUIPPED WITH A DIFFERENT AIR FILTER.NISSAN WILL REMOVE THE ORIGINAL AIR FILTER AND INSTALL A NEW UNIT WITH IMPROVED ANTI-FLAMMABILITY CHARACTERISTICS.ODI IS AWARE OF 26 REPORTS OF FIRE (OF WHICH THREE WERE REPORTED DIRECTLY TO BOTH ODI AND NISSAN) AND NO INJURIES.THIS INVESTIGATION IS CLOSED.

ON JUNE 28, 2006 NISSAN SUBMITTED TO THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) A PART 573 REPORT ADVISING THAT CERTAIN MODEL YEAR 2003 NISSAN SENTRA AND NISSAN ALTIMA SEDANS EQUIPPED WITH 2.5L ENGINES WOULD BE RECALLED TO REPROGRAM THE ELECTRONIC CONTROL MODULE (ECM). THE RECALL IS IDENTIFIED BY NHTSA RECALL NO. 06V242. THE SUBJECT POPULATIONS OF THE RECALL ARE 14,587 NISSAN SENTRA VEHICLES AND 186,279 NISSAN ALTIMA VEHICLES.NISSAN DETERMINED THAT THE OPERATION OF THE CRANK ANGLE SENSOR IN ALTIMA AND SENTRA SEDANS EQUIPPED WITH A 2.5L ENGINE WAS SIGNIFICANTLY AFFECTED BY TEMPERATURE VARIATIONS DUE TO THE UNIQUE LOCATION OF THE SENSOR. UNDER CERTAIN DRIVING CONDITIONS THE TEMPERATURE VARIATIONS MAY CAUSE A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR.IF THE INTERRUPTION IS BRIEF ENOUGH, SUCH THAT THE ELECTRONIC CONTROL MODULE (ECM) LOGIC DOES NOT HAVE TIME TO DIAGNOSE THE CONDITION, THE ENGINE MAY STOP RUNNING WHILE THE VEHICLE IS DRIVEN AT A LOW SPEED. AS A REMEDY, NISSAN WILL REPROGRAM THE ECM TO PREVENT THE STALLING INCIDENTS DUE TO SIGNAL INTERRUPTIONS FROM THE CRANK ANGLE SENSOR.ADDITIONALLY, AS PART OF THE RECALL QUERY, NISSAN WAS REQUESTED TO PROVIDE COMPLAINT INFORMATION FOR MY 2004 ALTIMA FOR COMPARATIVE PURPOSES.NISSAN HAS INDICATED TO ODI THAT THE SCOPE OF THE RECALL IS LIMITED TO THE MY 2003 AS COMPARATIVELY, THE MY 2004 COMPLAINT RATE IS SUBSTANTIALLY LOWER. ODI WILL CONTINUE TO MONITOR THE COMPLAINT RATE OF THE MY 2004 ALTIMA. ACCORDIN

THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED THIS INVESTIGATION ON OCTOBER 18, 2002 BASED ON THREE REPORTS INDICATING THAT THE ENGINE COMPARTMENT IN MODEL YEAR (MY) 2002 NISSAN ALTIMA VEHICLES EQUIPPED WITH THE 2.5 LITER ENGINE CAUGHT ON FIRE WITHOUT ANY WARNING TO THE DRIVER WHILE THE VEHICLE WAS DRIVEN AT HIGHWAY SPEEDS.ONE NON-BURN RELATED INJURY WAS REPORTED AS A RESULT OF THE COMPLAINANT EXITING THE VEHICLE IN HASTE AFTER IT HAD CAUGHT ON FIRE.NISSAN DISCOVERED THAT ONE OF THE HANGER PINS WHICH HOLDS EXHAUST PIPE IN PLACE MAY CATCH DEBRIS FROM THE ROAD.IF THE DEBRIS WERE TO COME IN CONTACT WITH THE MAIN CATALYST, A FIRE COULD RESULT.THIS CONDITION IS ALSO PRESENT IN MY 2003 NISSAN ALTIMA VEHICLES BUILT THRU FEBRUARY 18, 2003.NISSAN ALSO STATED IN ITS DEFECT INFORMATION REPORT THAT ON MY 2002 ALTIMAS AND SENTRAS (EQUIPPED WITH THE 2.5-LITER ENGINE) THAT CERTAIN OPERATING CONDITIONS MAY CAUSE THE PRE-CATALYST TO OVERHEAT, WHICH WOULD CAUSE CATALYST SUBSTRATE PARTICLES TO FLOW INTO THE ENGINE.THESE PARTICLES CAN SCORE THE CYLINDER WALLS WHICH RESULTS IN INCREASE OIL CONSUMPTION.IF THE ENGINE OIL LEVEL IS LOW, ENGINE NOISE AND DAMAGE CAN OCCUR WHICH COULD RESULT IN A FIRE.THE RECALL INCLUDES 268,000 MY 2002-2003 ALTIMAS AND 2002 SENTRAS EQUIPPED WITH THE 2.5-LITER ENGINE.TO CORRECT THE CONDITION NISSAN WILL REMOVE THE PROTRUDING PORTION OF THE EXHAUST PIN ON THE ALTIMAS.NISSAN IS DEVELOPING A CORRECTIVE ACTION TO ADDRESS THE PRE-CATALYST.IN ADDITION TO THE CORRECTIVE ACT
