2003 Nissan Sentra — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 240 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Engine95 (39.6%)Official recall records for this system: 13, covering model years 1995–2006.
• Electrical system37 (15.4%)Official recall records for this system: 12, covering model years 2000–2017.
• Fuel system18 (7.5%)Official recall records for this system: 4, covering model years 2005–2013.
• Air bags (restraint system)16 (6.7%)Official recall records for this system: 36, covering model years 2002–2024.
• Exhaust & emissions control10 (4.2%)Official recall records for this system: 1, covering model years 2002.
• Brakes9 (3.8%)Official recall records for this system: 7, covering model years 1995–2019.

Other / uncategorized: 9 classifications (3.8%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.

These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.

What the records are about, by source

Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.

• Owner complaints (10,998 records, model years 1995–2026) are most frequently classified under: powertrain (transmission & drivetrain), engine and electrical system.
• Safety recalls (199 records, model years 1995–2026) are most frequently classified under: air bags (restraint system), lights and electrical system.
• Transport Canada recalls (165 records, model years 1995–2025) are most frequently classified under: air bags (restraint system), engine and visibility (glass, wipers, mirrors).
• Manufacturer communications (3,655 records, model years 1995–2026) are most frequently classified under: electrical system, equipment & accessories and engine.
• Investigations (30 records, model years 1995–2014) are most frequently classified under: air bags (restraint system), brakes and suspension.

"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records

Mileage reported when the issue occurred

• 138reports included a mileage
• 72,513average of those mileages

This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.

Diagnostic codes found in evidence for this vehicle

These codes appear by explicit identifier in official records matched to this exact model and year.

• U1000 in 2 records
• P0100 in 1 record
• P0102 in 1 record
• P0442 in 1 record

A code appearing in a record means the code was named in that document. It is not a diagnosis of this vehicle, not a fault this vehicle has, and not an indication of urgency. Diagnosis requires reading live data from the vehicle.
