Fuel pump failure on the 2001 Chevrolet Cavalier
Only 7 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 fuel pump failure gets reported
There are 12 reports of fuel pump failure on the 2001 Chevrolet Cavalier, 7 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 85,000 miles. It is the 9th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 43,000 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 $600–$2,600 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 9 model years of this car. It shows up earliest on the 2000, at a median of 40,000 miles, and latest on the 1999 at 160,000 miles.
By volume the 2003 carries the most reports, with 346; the 2001 has 12. 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.
Since purchasing the 2001 chevrolet cavalier, let me tell you, it has truly been like a rock thrown in the water. Less than 3000 miles on the car and I had to bring the car in to the dealership and was told that the alternator was defective. The car almost died on me on the road while making a left turn across two lanes of traffic. I was late for work, and I was stuck in the wal-mart parking lot for four hours. I finally got over that. Of course, I didn't take out the extended warranty, which if I had known that when I purchased this vehicle that I was getting a lemon, I definitely would have been a true sour puss and bought a ford. Recently I have had problems with the fuel, not only does it not get good gas mileage that it should, I was recently told that the fuel pump inside the gas tank failed. $643.77 later, I have my lemon back, after not having a car for work for a full week. The dealerships around my area were sold out of the fuel pumps, when talking to several parts salesman, I was told that they had a run on fuel pumps due to their failures, they sell several per week. Huh, imagine that? I have 43,000 miles and my…

Driving on 4 lane interstat in center lane when fuel pump failed. The car just stopped running as cars doing in excess of 65 MPH flew by me. Luckily I was able to roll into right lane, then sholder to call aaa for a tow. I could have been killed if the cars behind were not observant. *ak

How far this goes
This page is kept out of search results because 12 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 12 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 fuel pump failure happen on the 2001 Chevrolet Cavalier?
Across 7 owner reports that included an odometer reading, half were filed by 45,000 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 fuel pump failure on the 2001 Chevrolet Cavalier?
12 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.
