Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 2001 NISSAN Sentra. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
CERTAIN ANZO COMBINATION HEADLAMP ASSEMBLIES SOLD AS REPLACEMENT LAMPS FOR USE ON CERTAIN PASSENGER VEHICLES. SOME COMBINATION LAMPS ARE NOT EQUIPPED WITH AMBER SIDE REFLECTORS WHICH FAIL TO CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT."
Consequence
WITHOUT THE AMBER REFLECTORS, THE VEHICLE WILL BE POORLY ILLUMINATED, POSSIBLY RESULTING IN A VEHICLE CRASH.
Remedy
ANZO WILL NOTIFY OWNERS AND REPLACE THE HEADLAMPS FREE OF CHARGE. THE RECALL BEGAN MAY 9, 2006. OWNERS MAY CONTACT ANZO USA AT 909-468-3688.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE COOLING HOLES IN THE STEEL WHEEL MAY HAVE BURRS ON THEIR EDGES AS A RESULT OF IMPROPER MANUFACTURING. THESE BURRS CAN CAUSE CRACKS AS THE VEHICLE IS BEING DRIVEN. CRACKS CAN PROPAGATE BETWEEN ADJACENT COOLING HOLES. IF ENOUGH CRACKS DEVELOP BETWEEN THE COOLING HOLES, THE WHEEL COULD FAIL AND SEPARATE FROM THE MOUNTING HUB WITHOUT PRIOR WARNING.
Consequence
SEPARATION OF THE WHEEL FROM THE VEHICLE WHILE BEING OPERATED COULD RESULT IN A VEHICLE CRASH.
Remedy
DEALERS WILL INSPECT FOR CRACKS AND REPLACE THE WHEEL IF CRACKS ARE DISCOVERED. OWNER NOTIFICATION WILL BE CONDUCTED IN TWO PHASES. THE FIRST MAILING BEGAN OCTOBER 1, 2001, ASKING OWNERS TO BRING THEIR VEHICLES IN TO A DEALER FOR INSPECTION OF THE WHEELS. ANY WHEELS WITH CRACKS WILL BE REPLACED. A SECOND OWNER NOTIFICATION WILL BEGIN IN EARLY DECEMBER, AT WHICH TIME NISSAN WILL HAVE AN ADEQUATE NUMBER OF REPLACEMENT WHEELS, REQUESTING OWNERS TO RETURN TO THEIR DEALERS TO HAVE THE WHEELS REPLACED. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT NISSAN AT 1-800-647-7261.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH THE QG18DE ENGINE OR QR25DE ENGINES, THE FOAM MATERIAL USED FOR THE INTERIOR LINING OF THE ELECTRONIC CONTROL MODULE (ECM) BOX EMITS SULFUR AS IT CURES.
Consequence
IF ONE OF THE RESISTORS INSIDE THE ECM HAS A CRACK ON THE SURFACE COATING, THE GAS MAY CAUSE CORROSION OF THE RESISTOR. THIS COULD CAUSE THE MALFUNCTION INDICATOR LIGHT TO COME ON, POOR DRIVABILITY (IDLE INSTABILITY, POOR ACCELERATOR), OR THE ENGINE TO STOP RUNNING DURING VEHICLE OPERATION, WHICH COULD RESULT IN A CRASH.
Remedy
DEALERS WILL REMOVE THE INSIDE LINING MATERIAL FROM THE ECM BOX. OWNER NOTIFICATION BEGAN ON DECEMBER 22, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-647-7261.
ON CERTAIN PASSENGER VEHICLES, THE CIRCUIT BOARD FOR THE CRANK POSITION SENSOR OR CAM POSITION SENSOR MAY HAVE AN IMPROPER SOLDER JOINT DUE TO SOLDER DEFORMATION CAUSED BY HEAT STRESS ACCELERATED BY THE EXISTENCE OF FLUX RESIDUE DURING THE SOLDERING PROCESS.
Consequence
THIS COULD CAUSE THE "SERVICE ENGINE SOON" WARNING LIGHT TO COME ON, CREATE A NO START CONDITION, CAUSE REDUCED ENGINE POWER, OR CAUSE THE ENGINE TO STOP RUNNING WITHOUT WARNING DURING VEHICLE OPERATION, WHICH COULD RESULT IN A CRASH.
Remedy
DEALERS WILL REPLACE THE CRANK POSITION SENSORS. CAMSHAFT POSITION SENSOR(S), AND IN SOME CASES, THE VARIABLE TIMING CONTROL SENSOR(S). VEHICLES INVOLVED IN A PREVIOUS RECALL CAMPAIGN, 01V357, ARE ALSO INCLUDED IN THIS NEW CAMPAIGN. THE REPLACEMENT SENSORS USED IN THAT CAMPAIGN ARE ALSO AFFECTED. OWNER NOTIFICATION BEGAN ON DECEMBER 22, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-647-7261 OR INFINITI AT 1-800-662-6200.
VEHICLE DESCRIPTION: CERTAIN PASSENGER VEHICLES FAIL TO COMPLY WITH REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT." THESE VEHICLES WERE MISSING TAMPERPROOF CAPS THAT PREVENT HORIZONTAL HEADLAMP ADJUSTMENT.
Consequence
THESE CAPS ARE INSTALLED TO PREVENT MISADJUSTMENT OF THE HEADLAMPS.
Remedy
DEALERS WILL INSTALL A TAMPERPROOF CAP OVER THE HORIZONTAL ADJUSTMENT SCREW FOR BOTH HEADLAMPS. OWNER NOTIFICATION BEGAN JANUARY 14, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT NISSAN AT 1-800-647-7261.
ON CERTAIN ELECTRIC VEHICLES, THE FRONT SUSPENSION TRANSVERSE LINK'S BALL JOINT BRACKET MAY BREAK FROM STRESS CONCENTRATION AT A NOTCH CREATED BY SURFACE ROUGHNESS AND THE SHAPE OF THE MATERIAL CUT-LINE.
Consequence
Remedy
DEALERS WILL REPLACE THE BRACKET ON THESE VEHICLES. OWNER NOTIFICATION BEGAN DECEMBER 15, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-647-7261.
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH A 1.8 LITER ENGINE. THE ENGINE COULD STOP RUNNING WHILE BEING DRIVEN DUE TO A DEFECTIVE CRANK POSITION SENSOR. THIS COULD ALSO RESULT IN THE "SERVICE ENGINE SOON" WARNING LIGHT COMING ON OR REDUCED ENGINE POWER.
Consequence
IF THE ENGINE STOPS RUNNING WHILE THE VEHICLE IS IN MOTION, IT COULD RESULT IN A CRASH.
Remedy
DEALERS WILL REPLACE THE CRANK POSITION SENSORS. OWNER NOTIFICATION BEGAN DECEMBER 10, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT NISSAN AT 1-800-647-7261.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. ONE OR MORE OF THE THREE BOLTS USED TO ATTACH EACH FRONT SUSPENSION LOWER CONTROL ARM TO THE BODY ON THE LEFT AND RIGHT SIDES MAY NOT HAVE BEEN PROPERLY MANUFACTURED.
Consequence
THE BOLTS COULD FRACTURE, INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL REPLACE THE LOWER CONTROL ARM ATTACHMENT BOLTS. OWNER NOTIFICATION BEGAN JUNE 30, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT NISSAN AT 1-800-647-7261.

Complaints across nearby Nissan Sentra model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.

The checked bulk snapshot returned zero investigation action numbers for 2001 NISSAN Sentra. That is source coverage, not proof that no issue exists or will be investigated later.

The canonical URL is this file’s permanent public identifier. Source IDs and timestamps show exactly what was matched and when; they do not turn the evidence into a verdict.
Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.

Diagnose first. Confirm fitment.
These are transparent searches, not diagnoses or endorsed parts. Recall remedies come before purchases; exact part fitment requires VIN, trim, powertrain, production date and OE number.
