2002–2006

Gen 3 (L31, 2002-2006)

The L31 generation covers 2002 through 2006 (Cars.com, CarBuzz). It predates the CVT, which CarBuzz says arrived with the next generation. The 2002 model year draws the most press attention (24/7 Wall St).

NHTSA complaints per catalog listing run from 13.73 for 2006 (824 complaints across 60 listings) to 149.57 for 2002 (1,047 across 7), against a generation median of 39.43. The highest year, 2002, is 3.8 times that median. No year reaches the 2.0x our rule needs together with an above-median ad share and 30 or more listings, so nothing is flagged. Our catalog holds fewer than 30 cars each for 2002, 2003 and 2004, so those yearly rates are small-denominator figures and our rule cannot flag them; read the raw NHTSA counts.

What happens at what mileage

MilesItemCostNotes
about 102,500 (average of 2002 complaints) Catalytic converter failure (check engine light, P0420 or P0430) $2,360 average reported on 2002 cars (CarComplaints). RepairPal's all-years Altima converter average is $1,577 to $1,682, and MechAI gives $600 to $2,400 for a Nissan bank 2 converter. The mileage and the $2,360 come from a CarComplaints page for the 2002 model year, so they describe one year, not the whole generation. Go-Parts warns that a new converter will not clear P0420 if the real cause is an oxygen sensor or exhaust leak, so get the cause diagnosed before paying for a converter. We read these figures from search-result snippets, not full pages.
any Crankshaft or camshaft position sensor failure (2.5L) Free at a Nissan dealer when open NHTSA recalls 03V455000 (2002-2003), 06V242000 (2003-2004) and 07V527000 (2002, 2005-2006) cover crank and cam position sensors on the 2.5L. Confirm each by VIN; a stalling or no-start history is the symptom to ask about.
not stated by the sources 2.5L excessive oil consumption (2006) Free at a Nissan dealer when open NHTSA recall 06V223000 covers certain 2006 cars with the 2.5L for excessive oil consumption. Ask for the oil change history and check the level on the test drive.
any Rear subframe cracking (2006) Free at a Nissan dealer when open NHTSA recall 06V046000. Look under the rear of the car for corrosion and cracks at the subframe mounts; confirm the recall by VIN.

Years flagged

No year in this generation was flagged. A year is flagged by our rule only when all three hold: (1) its NHTSA complaints per catalog listing is at least 2.0x the median for its generation, (2) the share of ads that mention a problem is above the generation median, and (3) we track at least 30 listings for that year. The cutoff was fixed before we looked. Ad mentions are not failures, and a flag is a reason to inspect harder, not a verdict on any one car. We also re-ran the ad test with the 'rust' flaw left out, because the ad reader counts phrases like 'no rust' as mentions, and publish a flag only if it passes both ways.

2002 to 2006 Altimas in our catalog clear between $2,000 and $2,900 depending on year (128 cleared sales in total). The lowest yearly median is 2004 at $2,000 (7 sales) and the highest is 2002 at $2,900 (7 sales). Years with fewer than 50 cleared sales: 2002, 2003, 2004, 2005. Read those loosely.

Questions people actually ask

What Nissan Altima years should you avoid?

We don't tell you to skip a year; we flag by a fixed rule, and it flags 2009 and 2019. 2009 has 13.68 NHTSA complaints per catalog listing (1,601 complaints across 117 listings) against a 2007-2012 median of 5.25. Third-party lists most often name 2002 (24/7 Wall St) and the CVT years. 2002 has 1,047 complaints across 7 listings in our NHTSA pull, but only 7 catalog listings, so the rule cannot flag it. 2013 has 2,314 complaints across 325 listings, the most of any year.

How much does an Altima CVT replacement cost?

CoverageX puts it at about $4,800 to $5,500 at a Nissan dealer. DMV JDM Depot gives a wider $1,500 to $8,000, and I-90 Nissan says $5,000 to $8,000+ for a remanufactured unit. One 2015 owner reported a $5,900 AAMCO quote at 202k miles. These are search-result snippets, not full-page reads.

Did Nissan extend the Altima CVT warranty?

Yes. Nissan's May 2020 bulletin extends the CVT warranty on 2013-2016 Altimas from 60 months/60,000 miles to 84 months/84,000 miles, and its May 2023 bulletin does the same for 2017-2018 Altimas. Both say owners who opted out of the class action may not be covered, so check the VIN with a Nissan dealer. Coverage is measured from the original in-service date, so many of these cars are now past it.

Is the 2002-2006 Altima catalytic converter a known problem?

CarComplaints counts 131 catalytic converter failure complaints for the 2002 model year, with an average repair of $2,360 at 102,500 miles. RepairPal's average for an Altima converter is $1,577 to $1,682. Go-Parts warns a new converter will not clear a P0420 code if the cause is an oxygen sensor or exhaust leak. These are snippet reads.

Which Altima generation is the most reliable?

We don't rank reliability. The 2019-present generation has the lowest complaints per listing in our data (median 0.29 against 2.00 for 2013-2018), but newer cars have had less time to collect complaints, so that partly reflects age.

Does the Altima Hybrid have its own problems?

NHTSA lists the 2007-2011 Altima Hybrid under its own name. We merged its complaints into the Altima counts and did not analyze it separately.
