No-start or intermittent start failure on the 2002 Mercury Cougar
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 no-start or intermittent start failure gets reported
There are 4 reports of no-start or intermittent start failure on the 2002 Mercury Cougar, 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 88,000 miles. It is the 7th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 92,000 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 $200–$1,800 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 4 model years of this car. It shows up earliest on the 2000, at a median of 75,000 miles, and latest on the 2001 at 130,000 miles.
By volume the 2000 carries the most reports, with 22; the 2002 has 4. 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.
Purchased this used vehicle -- 3 days later, car would not start -- motor turned over, if was not getting gas. Brought gas to the car, it had only 1/4 of a tank, put more gas in, it eventually started. Took it for a diagnostic test -- fuel pump not functioning correctly. Recall 04n02 was issued for this model/yr car, not this vehicle VIN number, therefore ford will not stand behind this car problem and pay to have it fixed. *tr
Nhtsa campaign number:04v421000 manufacturer ford motor company was driving on a main city st. My auto stopped with no power in the left lane of busy 4 lane st. Would not start in neutral or park, man pushed it into the ctr. Lane out of traffic area. Policeman came after I called 911, after a few minutes he suggested taking key out stepping on brake then inserting key back in ignition, did that and it started right up, and he followed me to my st. And I got safely home. Prior to this shut down incident it had stalled going down a hill however put it in neutral and it started up again. This incident could have caused a serious accident, prior to this incident it had been cutting out for a couple of months which I thought was cheap gas, so changed to tectron. I have called ford on 3/15 twice and they said they can not do anything about it, I then researched this online and found this site and want to post exactly what happened to me as shown by the NHTSA on recall etc. It does show it is for the orig owner, I am the 2nd. Owner however this has occurred within the 15yr. Limitation you have posted for complaints explained to ford that…

How far this goes
This page is kept out of search results because 4 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 4 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 no-start or intermittent start failure happen on the 2002 Mercury Cougar?
Across 4 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 no-start or intermittent start failure on the 2002 Mercury Cougar?
4 reports have been filed with NHTSA, about 0.2 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.
