Engine sensor failure on the 2003 Infiniti I35
Only 6 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 engine sensor failure gets reported
There are 6 reports of engine sensor failure on the 2003 Infiniti I35, 6 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 95,000 miles. It is the 5th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 90,000 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 $180–$900 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, every year of the Infiniti I35
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.
October 3rd 2013 I was coming back from lunch driving back to work. While I was on the road driving my vehicle stopped in the middle of the road with cars still behind me. I was almost rear ended that day as I did not expect my vehicle to turn off while driving. I got the vehicle towed on october 3rd 2013 to r&s here in charlotte north carolina. The mechanic called me saturday october 5th 2013 and told that my crankshaft position sensor was what went out while I was driving. The mechanic also informed me that my car make model and year has recalls on crankshaft, camshaft and timing variable. I also checked myself and this information was true. Online recalls for year were engine and cooling and airbags. I got my car from carmax 2009 and never was informed of the recalls so that I could get the issue resolved. My car had one owner before I purchased the car from carmax. I called the infiniti toll-free consumer line and they did nothing but say its vehicle specific and that they seen nothing for my VIN number. My VIN should have been in a recall as I still have the same issues for recalls that never got fixed on my 2003 infiniti i35…
Recall - NHTSA campaign id number: 03v455000. Engine stopped while driving in normal conditions which could have caused a catastrophic accident. Loss complete control of the vehicle and the "slip" light, "tcs off" and "check engine light" all came on with complete engine failure while driving with no ability to regain control. I took the car to a mechanic and was told there is a code "p0340" - camshaft position sensor failure. Infiniti corporate had issued a recall # r3021 for this major issue. When I called infiniti corporate to take part of this serious recall and service my vehicle, they did not want to help claiming that they did not mark my VIN # for the recall. This is a major issue with most infiniti i35's and many nissans as well. Infiniti seems to not care and has put my life in complete jeopardy. *tr

How far this goes
This page is kept out of search results because 6 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 6 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 engine sensor failure happen on the 2003 Infiniti I35?
Across 6 owner reports that included an odometer reading, half were filed by 90,000 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 engine sensor failure on the 2003 Infiniti I35?
6 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.
