Exhaust leak or fumes in the cabin on the 2005 Nissan Altima
Only 4 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When exhaust leak or fumes in the cabin gets reported
There are 8 reports of exhaust leak or fumes in the cabin on the 2005 Nissan Altima, 4 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 100,000 miles. It is the 31st most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 115,443 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $250–$2,000 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 8 model years of this car. It shows up earliest on the 2014, at a median of 200 miles, and latest on the 2009 at 140,000 miles.
By volume the 2002 carries the most reports, with 20; the 2005 has 8. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Front passenger side floor board is rusting out badly with a big hole in the floor.I am worried that either someone's feet will fall through floor or there could be a case of carbon monoxide poison. I contacted nissan headquarters and mastria nissan dealer on 5-30-14 and was told," there is no recall on this, so they will not fix this issue".the dealer did say," they have heard about this issue on many altimas and have fixed it in the past for a cost of $755.00 per floor panel".I told them," if you know about this issue,why should I pay to fix it." *tr
I am the original owner of this vehicle. I found out on line , that there is an inferior design flaw which is extremely dangerous,that involves water accumulation and severe rusting clear thru both the inner and lower floor boards, on most 2002 to 2006 nissan's. I checked my vehicle and found on the front passenger side,I have a 6 to 8 inch hole clear thru both the inner and lower floor boards. This condition is extremely hazardous in that in addition to someone possibly falling thru the hole , engine exhaust carbon monoxide fumes as well as water can enter the vehicle. There is also the possibility of an electrical short in the wiring that can cause a fire and result in death. In reading about this defect on line it stats that repairing this problem can cost thousands of dollars and nissan knew of this rust problem , poor water drainage condition and will not issue a recall since this condition happened after the warranty period. The inter net articles stated that hundreds of complaints have already been filed and advised persons affected by this problem to contact the national highway traffic safety administration . I thank you…
I started leasing my altima in 2008 and purchased the car about 4 years later. I took it to have my muffler checked, because I heard noise, and it was found that the floorboard on the front , passenger side, is completely rusted out. The only thing between my passengers and the street is the carpet. Nissan said there is no recall. The car is only 11 years old!

How far this goes
This page is kept out of search results because 8 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 8 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does exhaust leak or fumes in the cabin happen on the 2005 Nissan Altima?
Across 4 owner reports that included an odometer reading, half were filed by 115,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is exhaust leak or fumes in the cabin on the 2005 Nissan Altima?
8 reports have been filed with NHTSA, about 0.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
