Other fuel system problem on the 2009 Harley-Davidson Flhx
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 other fuel system problem gets reported
There are 4 reports of other fuel system problem on the 2009 Harley-Davidson Flhx, 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 90,000 miles. It is the 3rd most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 19,896 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 $300–$2,200 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 Harley-Davidson Flhx
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.
Accelerating from a stop up to speed when lost throttle response, engine would not go above 1500-2000 RPM. Was able to limp to the side of the road. I shut bike down and waited a minute and restarted it. It started up and ran as normal. Talked to my local dealer and made them aware of the problem. They seemed very familiar with this issue and said to bring it in and they would give me a cost to fix. This seems to me to be a severe safety issue that should be on a manufactures recall. What if I were trying to get on the interstate and lost the ability to merge . *tr
While stopped at red light, as the light turned green, I proceeded to apply throttle with no response. Let out clutch and rolled no faster then 20 MPH while cars were backing up behind me. After rolling at 20 MPH for approximately hundred yards, I was able to pull over in a safe location with out being run over. *tr
I was just riding down the I-405 freeway near seattle, wa at about 70 MPH in the left with no shoulder available to pull over onto. The throttle suddenly failed and I had no power. I slowed dramatically and was nearly run over by a truck. I put on my flashers and moved 3 lanes right to get to the shoulder on the right. Traffic was heavy and I was fortunate not to be hit when I had no throttle control. I called a friend and he came about an hour later and towed me home. I feel that I was lucky not to have been hurt or killed in this incident.

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 other fuel system problem happen on the 2009 Harley-Davidson Flhx?
Across 4 owner reports that included an odometer reading, half were filed by 20,000 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 other fuel system problem on the 2009 Harley-Davidson Flhx?
4 reports have been filed with NHTSA, about 0.9 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.
