What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.
Owners filed 1,771 complaints with NHTSA about the 2000–2006 Nissan Sentra, and 1,149 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
Failures are spread across the mileage range, with the middle half between 32,880 and 106,000 miles. The median is 69,023 miles.
The most-reported areas are the engine and its cooling system (29.8% of complaints, typically around 66,000 miles), the electrical system (12.8% of complaints, typically around 75,000 miles), the airbag system (9.1% of complaints, typically around 98,000 miles).
3 recall campaigns cover this generation.

Which systems, and when
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 69,023 miles; the figures below show which parts of the car run ahead of that and which run behind.
The engine and its cooling system accounts for 29.8% of complaints (528 reports, 380 of them with a mileage figure), with a median of 65,502 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 39,000 and 93,900 miles.
A single system taking 29.8% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.
The electrical system accounts for 12.8% of complaints (226 reports, 167 of them with a mileage figure), with a median of 75,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 35,000 and 110,100 miles.
The airbag system accounts for 9.1% of complaints (161 reports, 67 of them with a mileage figure), with a median of 98,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 44,000 and 147,000 miles.
The engine accounts for 8.5% of complaints (150 reports, 129 of them with a mileage figure), and it fails late — a median of 110,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 75,150 and 140,000 miles.
The transmission and driveline accounts for 4.3% of complaints (77 reports, 47 of them with a mileage figure), with a median of 59,994 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 11,900 and 106,000 miles.
The fuel system accounts for 4.3% of complaints (76 reports, 60 of them with a mileage figure), with a median of 67,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 36,236 and 100,000 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2002 model year drew the most — 372 complaints — while 2006 drew the fewest at 155. The median year sits at 236.
Recalls and what they cover
NHTSA records 3 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
The campaigns cluster around the airbag system (3). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.
Reported severity
Of the 1,771 complaints filed against this generation, 173 reported a crash; 21 reported a fire; 128 reported an injury; 1 reported a fatality. Crash-involved reports represent 9.8% of the total.
These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.
What this means if you are buying one
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 32,880 and 106,000 miles, with a median of 69,023. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the engine and its cooling system and the electrical system are where this generation's reports concentrate, so those are the areas worth a specific look. The engine and its cooling system in particular shows a median failure mileage of 65,502, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.
Documented problems
Engine (2.5l Qr25de) 2002–2006
Pre-catalyst substrate disintegrates and ceramic debris is drawn back into the cylinders, scoring bores and producing runaway oil consumption and engine failure — the same mechanism as the contemporaneous Altima 2.5.
Engine (1.8l Qg18de) 2000–2006
Catalytic converter and oxygen sensor failures plus excessive oil consumption at higher mileage.
Engine Management 2000–2006
Crankshaft position sensor failures causing stall-while-driving.

What owners reported
The car shut of while driving at 65 MPH. The car restarted after 10 minutes drove about 2 miles and it shut of again. This time i called a mechanic and had the car towed to his shop. The mechanic indicated that it was a crankshaft and camshaft sensor issue. I have changed all other sensors on car. I was told that…
